Abstract When a building is demolished, its cohesive and planned structure fractures into countless fragments. These heterogeneous and disorganised fragments blur the boundaries between what was once private - the domestic space - and what is now public - the formerly occupied land. In 2019, I stumbled upon a family photograph amidst the rubble left by the demolition of the last towers of the Bairro do Aleixo in Porto. Constructed in the 1970s, this was a public housing estate designed to accommodate families from Ribeira-Barredo who had been displaced due to urban redevelopment. Throughout the years, the five towers have hosted a sizable and fluctuating population that has adapted and made use of this previously unconventional housing model. From 2011 to 2019, Aleixo underwent three demolition operations, politically supported by arguments citing its structural and social deterioration as justification. The first two were striking implosions broadcasted on television, whereas the final demolition, which I witnessed, unfolded as a slow deconstruction spanning several months. In the photograph, the woman dressed in white poses on a balcony of Tower 1 within the old Bairro do Aleixo. In the background stands the phallic skeleton of Tower 4, which would be imploded decades later. Upon its unearthing, the photograph, weathered by time and circumstance, hinted at a conceptual connection with the debris surrounding it. In this article, my focus centres on this found photograph, aiming to unveil the processes and tensions encapsulated within this fragment. I draw on the ontological connections between photography and death, as well as between photography and ruin, to analyse the spectral image of this obliterated site. I delve into what the encounter with this image might reveal about the memory of the neighbourhood, its public image, and the extensive and violent process of displacing its residents. I reach the concept of a "rubble-image" as pivotal in interpreting this nearly vanished imprint that stubbornly affirms the persistence of a dissenting and complex place, supposedly erased from public space and suppressed from urban memory by dominant sensibilities.

Resumo Quando uma edificação é demolida, a sua estrutura, unitária e planeada, é desintegrada em incontáveis fragmentos. Heterogéneos e desordenados, estes fragmentos borram os limites entre o que era privado - o espaço doméstico - e o que é público - o terreno antes ocupado. Em 2019, encontrei uma fotografia familiar entre os escombros da demolição das últimas torres do Bairro do Aleixo, no Porto. Este foi um conjunto de habitação pública construído na década de 1970 para realojar famílias da Ribeira-Barredo, deslocadas por uma reabilitação urbana. Ao longo do tempo, as cinco torres abrigaram uma população numerosa e mutável que se apropriou desse modelo de habitação até então incomum. Entre 2011 e 2019, o Aleixo foi alvo de três operações de demolição, politicamente justificadas por sua degradação estrutural e social. As duas primeiras foram implosões espetaculares e televisionadas, enquanto a última, que presenciei, foi uma lenta desconstrução que durou meses. Na fotografia, uma mulher vestida de branco posa numa varanda da Torre 1 do antigo Bairro do Aleixo. Ao fundo, paira o esqueleto fálico da Torre 4, implodida décadas depois. Quando encontrada, a fotografia, arruinada pelo tempo e pelas circunstâncias, sugeria uma afinidade conceptual com os escombros que a cercavam. Neste artigo, detenho-me sobre essa fotografia encontrada, objetivando desvelar os processos e as tensões armazenadas nesse fragmento. Recorro às relações ontológicas entre fotografia e morte, também entre fotografia e ruína, para analisar a imagem espectral desse sítio obliterado. Desenvolvo o que o encontro com ela pode indicar sobre a memória do bairro, a sua imagem pública, assim como o longo e violento processo de remoção dos seus moradores. Chego à noção de “imagem-escombro” como chave de leitura para esse vestígio quase desaparecido que afirma teimosamente a persistência de um lugar dissidente e complexo, pretensamente apagado do espaço público e suprimido da memória urbana pelas sensibilidades dominantes.

Abstract The purpose of this study was to determine if migration modifies the management and composition of agrobiodiversity in the homegardens, spaces where the richness of species ensures the provision of goods. In Dzoyaxché, Yucatán, we conducted semi-structured interviews and generated agrobiodiversity inventories in were applied to homegardens without migrants (SSM) and with migrants (SCM). The SSM recorded higher floristic and backyard fauna diversity; in SCM, there was a redistribution of management responsibilities. Thus, rural-urban migration, in Dzoyaxché, is a factor that determines agrobiodiversity.

Resumen El objetivo del estudio fue determinar si la migración modifica el manejo y la composición de la agrobiodiversidad en los solares, espacios donde la riqueza de especies asegura la provisión de bienes. En Dzoyaxché, Yucatán, se aplicó una entrevista semiestructurada y se realizó el inventario de la agrobiodiversidad a solares sin migrantes (SSM) y con migrantes (SCM). Los SSM registraron mayor diversidad florística y de fauna de traspatio; mientras que en SCM se registró una redistribución de las responsabilidades de manejo. En conclusión, la migración rural-urbana en Dzoyaxché es un factor que determina la agrobiodiversidad.

Abstract Green areas have important social, biological and aesthetical values. They might provide house and food for fauna, protect biodiversity and can provide several ecosystem services of provision, regulation, support and culture. This research aimed to analyze composition of native and exotic species in urban parks in São Paulo (Brazil), in response to variables considered drivers of diversity adapted to urban environment and to socioeconomic aspects. We expected that socio-economic factors and age and size of parks would be important determinants of species richness All county parks (municipal management) larger than 1 ha were selected, which summed 68 parks throughout São Paulo. Socioeconomic variables for this study were population, growth rate of population, average per capita income, IDH and population density. We also accessed native and exotic species richness of plants and trees from the flora list of each park. In order to determine the effects of park size and age and neighbourhood socio-economic status on richness of plants and trees we used multiple regression analyses. We found a great species richness in urban parks in São Paulo and that richness associated to park age and size, and to some socio-economic factors, especially when combined to age and size of parks. Bigger sites could offer more resources and area for the growth and establishment of native plants, and older parks in São Paulo likely had more management and interventions improving its biodiversity. Lastly, in vulnerable regions and in smaller and newer parks, we recommend improvement in plant species diversity by managers. social values fauna provision regulation culture Brazil, Brazil , (Brazil) aspects socio economic municipal selected 6 income density analyses Lastly managers (Brazil

Abstract Echinodorus is the second largest genus of the aquatic plant family Alismataceae, comprising 28 species, of which 24 occur in Brazil. This study represents the first record of Echinodorus scaber Rataj for the State of Maranhão, based on material collected in the Municipality of Brejo, eastern Maranhão. Echinodorus scaber shares morphological similarities with E. macrophyllus (Kunth) Micheli, but it can be distinguished by (I) a highly branched inflorescence, (II) scabrous peduncles and petioles covered by stellate trichomes, and (II) small flowers with reflexed petals. This new record of E. scaber contributes to a better understanding of this genus’ diversity and distribution in Maranhão and underscores the necessity to broaden collection efforts for a better comprehension of the state’s flooded zones. Comprehensive collection efforts, with a special focus on aquatic plants and in locations far from the state’s main urban center, São Luís, may result in a significant knowledge increase of the flora, especially of the genus Echinodorus, which needs a broad taxonomic study. These recommendations may result in new records, range extensions, and species descriptions, contributing to the conservation of the aquatic environments of Maranhão.

Resumo Echinodorus é o segundo maior gênero da família de plantas aquáticas Alismataceae, compreendendo 28 espécies, 24 delas ocorrendo no Brasil. Este estudo representa o primeiro registro de Echinodorus scaber Rataj para o Estado do Maranhão, com base em material coletado no município de Brejo, leste do Maranhão. Echinodorus scaber compartilha semelhanças morfológicas com E. macrophyllus (Kunth) Micheli, mas pode ser distinguida por: (I) uma inflorescência altamente ramificada; (II) pedúnculos e pecíolos escabrosos recobertos por tricomas estrelados; e (II) flores pequenas com pétalas reflexas. Este novo registro de E. scaber contribui para uma melhor compreensão da diversidade e distribuição deste gênero no Maranhão e ressalta a necessidade de ampliar os esforços de coleta para uma maior compreensão das zonas inundadas do estado. Esforços de coleta abrangentes, com foco especial em plantas aquáticas e em locais distantes do principal centro urbano do estado, São Luís, poderá resultar em um aumento significativo do conhecimento da flora, especialmente do gênero Echinodorus, que necessita de amplo estudo taxonômico. Essas recomendações poderão resultar em novos registros, extensões de distribuição e novas descrições de espécies, contribuindo para a conservação dos ambientes aquáticos do Maranhão.

Abstract Restinga formations are defined as the vegetation covering sandy coastal sediments deposited during the Quaternary period, regardless their physiognomy. They are usually characterized as areas of confluence between plant species associated with diverse phytogeographical domains. However, detailed floristic and biogeographic studies are still required to better define their distribution patterns, the origins of their plant species, and their biogeographical affinities. In this study, we investigate the floristic similarities among restingas in Northern and Northeastern Brazil and diverse ecosystems from different Brazilian phytogeographical domains (Caatinga, Cerrado, Atlantic Forest and Amazonia). We employed multivariate analyses to investigate differences in species composition and identify floristically similar groups. While sharing species with other ecosystems, restingas exhibit unique floristic composition, representing a coastal flora. Furthermore, the restingas of Northern and Northeastern Brazil are biogeographically subdivided according to previously recognized sectors of the coast of the country. These findings underscore the complex nature of restinga ecosystems, influenced by environmental factors such as geographic distance, geology and climate. These insights contribute to a nuanced understanding of the complex relationships between restingas and their surrounding ecosystems, facilitating informed conservation efforts in the face of escalating urban and industrial expansion along the Brazilian coast. period physiognomy However patterns affinities study Caatinga, Caatinga (Caatinga Cerrado Amazonia.

ABSTRACT Parietaria judaica and Soleirolia soleirolii (Parietariae, Urticaceae) are perennial herbs native to the Northern Hemisphere, inhabiting urban and peri-urban environments in various countries. In this work, the record for P. judaica is updated with the inclu- sion new localities and habitats in the province of Buenos Aires, naturalization areas of S. soleirolii in Argentina are also mentioned, as well as the invasion status for each species is established. Herbarium specimens of both species collected between 1989 and 2022 in different cities of Buenos Aires were studied. The habitats were docu- mented through observations in naturalized populations. S. soleirolii was found only in urban environments, whereas the distribution area of P. judaica expanded to new habitats in both urban and peri-urban sectors of Buenos Aires. The latter species has a long period of flowering and fruiting. This work also mentions its probable agents and pathways of dispersal. Illustrative images of the species and their habitats are provided, together with maps showing the geographic position of the populations, and a key feature is introduced, allowing to differentiate the genera of the Parietarie- ae tribe in Argentina. The invasion status of these species in Argentina is different.S. soleirolii is not currently a species with high invasive potential; on the contrary,P. judaica has a high propagule pressure, and probably advances along the railroad tracks; therefore its invasive potential is high. In addition, its pollen is allergenic.

RESUMEN Parietaria judaica y Soleirolia soleirolii (Parietariae, Urticaceae) son hierbas perennes originarias del hemisferio norte que habitan ambientes urbanos y periurbanos en diversos países. En este trabajo, se actualiza el registro para P. judaica con nuevas localidades y hábitats en la provincia de Buenos Aires, se hace referencia a los focos de naturalización de S. soleirolii en Argentina, y se establece el estado de invasión para cada especie. Se estudiaron ejemplares de herbario de ambas especies coleccio- nados entre 1989 y 2022 en varias ciudades de la provincia de Buenos Aires y se documentaron los hábitats que ocupan mediante observaciones en las poblaciones naturalizadas. S. soleirolii se halló solamente en ambientes urbanos. Asimismo, se amplió el área de distribución de P. judaica con registros en numerosas ciudades de la provincia de Buenos Aires, en diversos hábitats de sectores urbanos y periurba- nos. Presenta un amplio período de floración y fructificación. Se mencionaron sus probables agentes y vías de dispersión. Se aportaron imágenes ilustrativas de las especies y sus hábitats, mapas de la posición geográfica de las poblaciones halladas en Buenos Aires y, adicionalmente, una clave para diferenciar los géneros de la tribu Parietarieae en Argentina. El estado de invasión de las dos especies en Argentina es diferente. S. soleirolii no es actualmente una especie con alto potencial invasor. Por el contrario, P. judaica presenta una alta presión de propágulos, avanza probablemente por las vías del ferrocarril, por lo tanto, su potencial invasor es alto. Además, su polen es alergógeno.

Resumen La expansión urbana por lo general implica la ocupación informal de espacios naturales vulnerables, lo que conlleva al deterioro de estos ecosistemas. Este mismo fenómeno se presenta en el humedal de Purrumpama, ubicado en Huamachuco, una ciudad de la sierra liberteña del Perú. Por ello, el presente artículo planteó como objetivo realizar un análisis temporal de la flora presente en el humedal, contrastando los resultados obtenidos con un análisis temporal en Google Earth e identificando la relación con la expansión urbana. Para tal fin, se hizo uso imágenes satelitales Landsat 8 y Google Earth, delimitando el área de estudio según lo establecido por planes de la Municipalidad Provincial Sánchez Carrión. De esta manera, se determinó que existe una disminución constante de cobertura vegetal en las zonas Sur y Sur-este del humedal, calculando una pérdida de 74 792 m2 del humedal desde 2012 hasta 2021. Así mismo, se arguyó que las acciones ambivalentes de la municipalidad han legitimado la ocupación de viviendas y las acciones de control han sido ineficaces.

Resumo A expansão urbana geralmente implica na ocupação informal de espaços naturais vulneráveis, o que leva à deterioração desses ecossistemas. Esse mesmo fenômeno ocorre no pantanal de Purrumpama, localizado em Huamachuco, cidade da Sierra Libertad do Peru. Por esse motivo, o objetivo deste artigo foi realizar uma análise temporal da flora presente no pantanal, contrastando os resultados obtidos com uma análise temporal no Google Earth e identificando a relação com a expansão urbana. Para isso, foram utilizadas imagens de satélite Landsat 8 e Google Earth, delimitando a área de estudo conforme estabelecido pelos planos do Município Provincial de Sánchez Carrión. Dessa forma, apurou-se que há uma diminuição constante da cobertura vegetal nas áreas Sul e Sudeste do pantanal, calculando uma perda de 74.792 m2 do pantanal de 2012 a 2021. Da mesma forma, argumentou-se que as ações ambivalentes do município têm legitimado a ocupação de domicílios e as ações de controle têm sido ineficazes.

Abstract Urban expansion generally implies the informal occupation of vulnerable natural spaces, which leads to the deterioration of these ecosystems. This same phenomenon occurs in the Purrumpama wetland, located in Huamachuco, a city in the Sierra Libertad of Peru. For this reason, the objective of this article was to carry out a temporal analysis of the flora present in the wetland, contrasting the results obtained with a temporal analysis in Google Earth and identifying the relationship with urban expansion. For this purpose, Landsat 8 and Google Earth satellite images were used, delimiting the study area as established by the plans of the Sánchez Carrión Provincial Municipality. In this way, it will continue that there is a constant decrease in vegetation cover in the South and South-East areas of the wetland, calculating a loss of 74,792 m2 of the wetland from 2012 to 2021. Likewise, it was argued that the ambivalent actions of the municipality has legitimized the occupation of houses and control actions have been ineffective.

RESUMEN El arbolado urbano ofrece importantes servicios ambientales en las ciudades, razón por la cual su establecimiento y estudio se ha incrementado en los últimos años. En este trabajo se evaluó el cambio de la composición y diversidad del arbolado urbano en la ciudad de Linares, Nuevo León, México en un período de 26 años (1995-2021). Para esto se midió la altura y cobertura de copa, así como los índices de diversidad de Shannon y de similitud de Morisita-Horn. Se registraron 62 especies (22 nativas y 40 introducidas) pertenecientes a 56 géneros y 29 familias de árboles en todo el periodo evaluado. Las familias mejor representadas fueron Fabaceae con nueve especies, Fagaceae, Oleaceae y Rutaceae con cuatro y Apocynaceae y Moraceae con tres. Se observó un incremento en la densidad de árboles introducidos de 1995 a 1999, mientras que, en las últimas dos décadas, la densidad de especies nativas aumentó significativamente, como el caso de Quercus fusiformis y Fraxinus udhei. La mayor similitud de especies se registró en el periodo 1995-1999 (69,2 %) con especies compartidas como las exóticas Ficus benjamina y Ligustrum japonicum. La flora arbórea actual en las áreas públicas de Linares, es probablemente el resultado de un mayor conocimiento de la ecología de las especies tanto nativas como introducidas por parte de la sociedad, así como de las instituciones académicas y gubernamentales de Linares, Nuevo León.

ABSTRACT Urban trees offer important environmental services in cities, which is why their establishment and study has increased in recent years. In this work, the change in the composition and diversity of urban trees was evaluated in the small city of Linares, Nuevo León in a period of 26 years (1995 2021). For this, crown coverage was measured, and the Shannon diversity and Morisita-Horn similarity indices were obtained. As results, 62 species (22 native and 40 introduced) belonging to 56 genera and 29 tree families were recorded throughout the evaluated period. The best represented families were Fabaceae with 9 species, Fagaceae, Oleaceae and Rutaceae with 4 and Apocynaceae and Moraceae with 3. An increase in the density of introduced trees was observed from 1995 to 1999, while by 2021 those of native origin increased significantly as was the case with Quercus fusiformis and Fraxinus udhei. The highest species similarity was recorded in the 1995-1999 period (69,2 %) with shared species such as the exotic Ficus benjamina and Ligustrum japonicum. The current arboreal flora in the public areas of Linares is probably the result of a greater knowledge of the ecology of both native and introduced species by society, as well as the academic and governmental institutions of Linares, Nuevo León.

Abstract Lotic environments are subjected to the impacts of human activities in an intense way in urban regions and one of the ways to assist in the environmental diagnosis is through the knowledge of the composition of bioindicator organisms, including microalgae. The objective of this work was to qualitatively characterize the Chlorophyceae Class Wille, providing descriptions and meristic data of the specimens as well as the environmental conditions in which the taxa were recorded. Water and phytoplankton samplings were carried out quarterly in 2020, in nine supply rivers, distributed in three river basins in the western region of Paraná (Paraná III basin, Piquiri basin and Baixo Iguaçu basin). The studied rivers were classified as oligotrophic or mesotrophic and the taxa were mostly rare. Thirty-six taxa belonging to the Chlorophyceae class were recorded, distributed in five families: Hydrodictyaceae Dumortier, Neochloridaceae Ettl & Komárek, Radiococcaceae Fott ex P.C.Silva, Scenedesmaceae Oltmanns, Selenastraceae Blackman & Tansley. These taxa have mainly cenobial representatives, with about 70% of the individuals in this thallus configuration, followed by 22% colonies and 8% unicellular thallus. Among the identified species, five occurred only in mesotrophic sites, warning for environments with tendencies to elevate their trophic, since they are genera previously associated with these conditions. Ten new citations were recorded for the State of Paraná, namely: Pseudopediastrum boryanum var. longicorne (Reinsch) P.M.Tsarenko, Radiococcus skujae I.Kostikov, T.Darienko, A.Lukesová & L.Hoffmann, Desmodesmus perforatus (Lemmermann) E.Hegewald, Desmodesmus subspicatus (Chodat) E.Hegewald & A.W.F.Schmidt, Scenedesmus indicus Philipose ex Hegewald, Engelberg & Paschma, Ankistrodesmus bernardii Komárek, Monoraphidium capricornutum (Printz) Nygaard, Monoraphidium caribeum Hindák, Raphidocelis danubiana var. elegans (Playfair) Taşkin & Alp, Selenastrum rinoi Komárek & Comas. Taxonomic studies, such as this one, are an important tool for understanding the flora, and in addition to contributing to the registration of species in aquatic ecosystems, they serve as a basis for ecological studies and other approaches used to preserve biodiversity in these places. organisms microalgae Wille 2020 basin. . basin) rare Thirtysix Thirty six families Dumortier PCSilva P C Silva P.C.Silva Oltmanns Tansley representatives 70 configuration 22 8 sites trophic namely var Reinsch (Reinsch PMTsarenko M Tsarenko P.M.Tsarenko IKostikov I Kostikov I.Kostikov TDarienko T Darienko T.Darienko ALukesová A Lukesová LHoffmann L Hoffmann L.Hoffmann Lemmermann (Lemmermann EHegewald E Hegewald Chodat (Chodat AWFSchmidt W F Schmidt A.W.F.Schmidt Paschma Printz (Printz Nygaard Hindák Playfair (Playfair Alp Comas flora ecosystems places 202 7 2 20

Resumo Ambientes lóticos são ecossistemas muito vulneráveis aos impactos das atividades humanas, especialmente em regiões urbanas, e uma das formas para auxiliar no diagnóstico ambiental é utilizando o conhecimento da composição dos organismos bioindicadores, dentre eles as microalgas. O objetivo foi caracterizar qualitativamente as microalgas enquadradas na Classe Chlorophyceae Wille, fornecendo descrições e dados merísticos dos espécimes bem como as condições ambientais em que os táxons foram registrados. Foram realizadas amostragens de água e de fitoplâncton trimestralmente no ano de 2020, em nove rios de abastecimento, distribuídos em três bacias hidrográficas da região oeste do Paraná (bacia do Paraná III, bacia do Piquiri e bacia do Baixo Iguaçu). Os rios estudados foram enquadrados como oligotróficos ou mesotróficos e os táxons apresentaram em sua maioria ocorrência rara. Foram registrados 36 táxons pertencentes a classe Chlorophyceae distribuídos em cinco famílias: Hydrodictyaceae Dumortier, Neochloridaceae Ettl & Komárek, Radiococcaceae Fott ex P.C.Silva, Scenedesmaceae Oltmanns, Selenastraceae Blackman & Tansley. Esses táxons possuem representantes principalmente cenobiais, apresentando cerca de 70% dos indivíduos nessa configuração de talo, seguido por 22% de colônias e 8% de talos unicelulares. Entre as espécies identificadas, cinco ocorreram somente em locais mesotróficos, advertindo para ambientes com tendências a elevar sua trofia, visto que são gêneros já associados anteriormente a essas condições. Foram registradas 10 novas citações para o Estado do Paraná, sendo estas: Pseudopediastrum boryanum var. longicorne (Reinsch) P.M.Tsarenko, Radiococcus skujae I.Kostikov, T.Darienko, A.Lukesová & L.Hoffmann, Desmodesmus perforatus (Lemmermann) E.Hegewald, Desmodesmus subspicatus (Chodat) E.Hegewald & A.W.F.Schmidt, Scenedesmus indicus Philipose ex Hegewald, Engelberg & Paschma, Ankistrodesmus bernardii Komárek, Monoraphidium capricornutum (Printz) Nygaard, Monoraphidium caribeum Hindák, Raphidocelis danubiana var. elegans (Playfair) Taşkin & Alp, Selenastrum rinoi Komárek & Comas.

Abstract Biotic homogenization is a global phenomenon, mainly in urban areas where exotic species are dominant, contributing to the loss of native biodiversity. Gardening native flora to promote local biodiversity is becoming a conservation practice in urban settings. Therefore, in this study, we analyzed the representation of the Chilean native flora in the Chilean and international ornamental flower seed market to know which native plant seeds are sold. We found that native seed are absent in the local market and that the totality of seed supply in the market corresponds to species of exotic origin, mainly from the Palearctic region (43%). However, surprisingly, many Chilean flower seeds are traded in the international market (approximately 6% of the total Chilean flora). This lack of availability of native seeds for local consumers constitutes a bottleneck for ecological restoration initiatives. It is consistent with the greater abundance of exotic species in urban green areas and supports the hypothesis of biocultural homogenization. phenomenon dominant settings Therefore study sold origin 43%. 43 43% .

Abstract Green areas in urban landscapes are under strong anthropogenic pressure, and, at the same time are fundamental to maintaining biodiversity, as they provide resources for many animal and plant species. Knowing these species is fundamental for its maintenance and conservation, and inventories are extremely important for monitoring fauna and conserving it. Therefore, the goal of this research is to inventory the butterflies species in the park of the Instituto Butantan (Ibu), located in an urban area in the city of São Paulo, southeast Brazil. The surveys of butterflies were conducted through visual censuses from August 2017 to July 2019 and recorded a total of 324 butterfly species. The most speciose family was Hesperiidae, followed by Nymphalidae, Lycaenidae, Pieridae, Riodinidae, and Papilionidae. Among the sampled species, there is Euselasia zara which is a new record for the state of São Paulo. Neither the species accumulation nor the richness estimator curves tended to reach an asymptote, suggesting that additional butterflies’ species will be recorded with more sampling effort on the site. Even with a flora composed mainly of exotic and ornamental plants, the park of Instituto Butantan exhibits a very rich butterfly community. This community exhibits a pattern of seasonally variation, with the peak of species richness related to the rainy season. When compared with Cidade Universitária Armando de Salles Oliveira (USP), another nearby urban green area, which is larger, more heterogeneous and sampled over a longer period, it is possible to notice that the Ibu butterfly community is a subsample of this larger one. These results highlight the potential that urban parks have for the maintenance and conservation of butterfly species. pressure biodiversity Therefore Ibu, , (Ibu) Paulo Brazil 201 32 Hesperiidae Nymphalidae Lycaenidae Pieridae Riodinidae Papilionidae asymptote site plants variation season USP, USP (USP) period one (Ibu 20 3 (USP 2

Abstract The structure of urban secondary forests and their potential for meliponiculture in the eastern Amazon was studied in the municipality of Belterra, Pará. The sampling was carried out in 25 plots of 40 m2 in two areas (0.1 ha) of secondary forests (SF), in which three classes of DBH values were considered (C1:1 cm ≤ DBH ≤ 5 cm; C2: 5 cm < DBH ≤ 10 cm and C3: DBH ≥ 10 cm). a total of 230 individuals were registered in SF I, comprising 66 species and 27 botanical families and 185 individuals in SF II, comprising 43 species distributed in 24 botanical families. The highest richness and abundance were verified for C1, followed by C2 in both areas. In SF I, the basal area values (G=1.509) were higher than in SF II, while the total volume (V=20.21) was higher than SF I, the mean height for C3 was higher in SF II, and C1 and C2 were higher in SF I. The Shannon-Wiener diversity index was higher in SF I (H = 3.722) than in SF II (H=3.197). It was observed that 75% species have bee pollination systems (mellitophilous flora) and are thus considered sources of honey resources.

Abstract Medicinal plants have had worldwide cultural importance because of their use and preservation in rural communities and urban areas. The aim of this research was to determine the cultural significance that Kakchikel and Mochó ethnic groups, inhabitants of the Sierra Mariscal estate of Chiapas, give to their medicinal plants. A qualitative and quantitative approach was used with direct interviews and a questionnaire. The data provided by the respondents was used to build up a Microsoft Excel® database for descriptive statistics to estimate the number of plants used per illness, grouped according to the International Statistical Classification of Diseases and Related Health Problems of the WHO. Similarity of illnesses amongst ethnic groups was determined adopting the Jaccard index, and the Significant Use Level (TRAMIL) or cultural value per plant species was evaluated as well. Both ethnic groups are registered for some official or private medical services, but they prefer using medicinal plants, regardless of their literacy level. The Mochó ethnic group reported 93 illnesses and the Kakchikel 74, classified into 13 diseases groups according to the WHO, having a 28.5% of similarity index. Ten out of 167 illnesses were reported as the most common ailments, such as: coughing, headache, diarrhea, fever, flu, stomachache, diabetes, kidneys ailments, gastritis and wounds. From 209 as total of medicinal plants, the Mochó reported using 123 and the Kakchikel 86, from which 16 and 14 species had cultural significance respectively. Most used medicinal plants are Fennel (Foeniculum vulgare Mill.), common rue (Ruta graveolens L.) and verbain (Verbena litoralis Kunth.).

Resumen Las plantas medicinales han tenido importancia global y local en cuanto a su uso y conservación en las comunidades rurales y zonas urbanas. El objetivo de esta investigación fue determinar el Valor Cultural que las etnias Mochó y Kakchikel dan a la flora medicinal de su territorio en la Sierra Mariscal, Chiapas. En esta investigación se utilizó un enfoque mixto (cualitativo y cuantitativo), con el apoyo de entrevistas dirigidas y aplicación de un cuestionario. La información proporcionada por los entrevistados se integró en una base de datos de Microsoft Excel® para determinar el número de plantas usadas por las etnias para atender sus padecimientos, de acuerdo con la Clasificación Internacional de Enfermedades y Problemas Relacionados con la Salud (CIE-10) de la Organización Mundial de la Salud. Se determinó el índice de similitud de enfermedades entre etnias adaptando el índice de Jaccard, y se obtuvo el Valor Cultural TRAMIL de las plantas medicinales para atender sus padecimientos. Aunque los integrantes de ambas etnias se encuentran afiliados en algún servicio médico oficial o acuden al médico particular, los entrevistados indicaron preferir el uso de plantas medicinales independientemente de su escolaridad. La etnia Mochó reportó 93 padecimientos y la Kakchikel 74, distribuidos en 13 grupos de enfermedades, teniendo un índice de similitud de 28.5%. Del total de los padecimientos, diez fueron comunes en ambas etnias: tos, dolor de cabeza, diarrea, fiebre, gripe, dolor de estómago, diabetes, riñones, gastritis y heridas. De las 209 plantas reportadas, 123 corresponden a la etnia Mochó y 86 a la etnia Kakchikel, de las cuales 16 y 14 respectivamente tuvieron un Valor Cultural; y las plantas medicinales más usadas son Hinojo (Foeniculum vulgare Mill.), Ruda (Ruta graveolens L.) y Verbena (Verbena litoralis Kunth.).

ABSTRACT Introduction: Liquid-based cytology is a method that can contribute to the early identification of microscopic changes in the uterine cervix that can progress to malignancy, by reducing the number of unsatisfactory samples compared to conventional cytology. Objective: To analyze the microscopic characteristics identified by liquid-based cytology of the uterine cervix in women treated at the Student Welfare Unit of the Technical University of Manabí, Ecuador. Methods: A descriptive, cross-sectional, retrospective and quantitative study was carried out where the sociodemographic, microbiological and histological characteristics collected in the medical records of 132 women who participated in the Pap smear campaign carried out during June 2019 were analyzed. Results: The age range that prevailed was 19 to 33 years who lived in urban areas, 64% of women began their sexual life before or at 18 years of age. The microbiological findings showed the presence of coccoid flora in 50% and 100% of the samples showed adequate quality. The cytological study presented, according to the Bethesda system, 75% of negative samples, with 13% low-grade IEL and 11% ASCUS. The background of the mild inflammatory smears was present in 52%, the history of previous positive cytology in 34% was more than three. All of the samples were useful. No relationship was found between the presence of intraepithelial lesion and the age of the patients (p=0.3076). Conclusions: CBL can ensure a higher quality of histological diagnosis by guaranteeing a greater number of useful samples.

RESUMEN Introducción: La citología líquida es un método que puede contribuir a identificar de manera precoz los cambios microscópicos del cérvix uterino que pudieran progresar a la malignidad, al disminuir el número de muestras insatisfactorias en relación a la citología convencional. Objetivo: Analizar las características microscópicas identificadas mediante la citología de base líquida del cérvix uterino en mujeres atendidas en la Unidad de Bienestar Estudiantil de la Universidad Técnica de Manabí, Ecuador. Métodos : Se realizó un estudio de serie de casos donde se analizaron las características sociodemográficas, microbiológicas e histológicas procedentes de las fichas médicas de 132 mujeres que participaron en la campaña de Papanicolaou realizado durante junio de 2019. Resultados: El rango de edad predominante fue el de 19 a 33 años, residían en área urbana, 64 % de las mujeres inició la vida sexual antes o durante sus 18 años. Los hallazgos microbiológicos mostraron presencia de flora cocoide en 50 % y 100 % de las muestras manifestaron la calidad adecuada. El estudio citológico presentó, según el sistema Bethesda, 75 % de muestras negativas, con 13 % de LIE de bajo grado y 11 % de ASCUS. El fondo del frotis inflamatorio leve se presentó en 52 %, mientras los antecedentes de más de tres citologías anteriores positivas resultaron en 34 % de las féminas. No se encontró relación entre la presencia de lesión intraepitelial y la edad de las pacientes (p=0,3076). Conclusiones: El total de las muestras fueron útiles lo cual puede indicar que la citología de base líquida ofrece una mayor calidad del diagnóstico histológico.

Abstract: Background and Aims: Bahia is one of the Brazilian states with the greatest diversity of orchids. Species restricted to microhabitats or forming small populations, being subject to local suppression, have been reported for restingas of the state. The north coast of Bahia has recently been exposed to intense anthropic pressures, including disordered occupation of land and predatory tourism. In order to encourage the adoption of regional conservation strategies, we carried out a survey of the orchid flora in the Parque Natural Municipal da Restinga de Praia do Forte (PNMR Praia do Forte), a fragment of restinga on the north coast of the state. Methods: Field work was conducted monthly from September 2016 to December 2017, and in July 2020 and August 2022, by employing the walking survey method. We consulted collections of the herbaria ALCB, HRB, HUEFS, and RB in person, as well as digital images of type specimens deposited in European herbaria and the Environmental Information Reference Center database. Phenological and distribution data of the species in the phytophysiognomies of PNMR Praia do Forte were mostly obtained in the field. Key results: Orchidaceae is represented by 14 genera and 16 species in the PNMR Praia do Forte, most of which are native to the Neotropics (14 spp., including eight endemic to Brazil), mainly terrestrial (six spp.), occurring exclusively in restinga forest formations (eight spp.). Epistephium williamsii, Gomesa barbata, Oeceoclades maculata, Pachygenium parvum, Polystachya concreta and Prescottia leptostachya (restricted to Bahia state) form small populations (<50 individuals). Conclusions: The orchid flora of the PNMR Praia do Forte, especially the aforementioned species, requires the attention from managers, in order to implement possible management and conservation actions and prevent them from being suppressed locally. We suggest greater surveillance actions in the park and environmental education actions among local residents and tourists.

Resumen: Antecedentes y Objetivos: Bahía es uno de los estados brasileños con mayor diversidad de orquídeas. Para restingas del estado se han reportado especies restringidas a microhábitats o que forman pequeñas poblaciones, estando sujetas a supresión local. La costa norte de Bahía ha estado expuesta recientemente a intensas presiones antrópicas, incluida la ocupación desordenada de la tierra y el turismo depredador. Con el fin de fomentar la adopción de estrategias de conservación regionales, llevamos a cabo un estudio de la flora de orquídeas en el Parque Natural Municipal da Restinga de Praia do Forte (PNMR Praia do Forte), un fragmento de restinga en la costa norte del estado. Métodos: El trabajo de campo se realizó mensualmente desde septiembre 2016 a diciembre 2017, así como en julio 2020 y agosto 2022, empleando el método de caminata libre. Consultamos personalmente las colecciones de los herbarios ALCB, HRB, HUEFS y RB, así como la base de datos del Centro de Referencia de Información Ambiental e imágenes digitales de especímenes tipo depositados en herbarios europeos. Los datos fenológicos y de distribución de las especies en las fitofisonomías del PNMR Praia do Forte se obtuvieron principalmente en el campo. Resultados clave: Orchidaceae está representada por 14 géneros y 16 especies en el PNMR Praia do Forte, en su mayoría nativas del Neotropico (14 spp., incluidas ocho endémicas de Brasil), principalmente terrestres (seis spp.), ocurriendo exclusivamente en formaciones forestales de restinga (ocho spp.). Epistephium williamsii, Gomesa barbata, Oeceoclades maculata, Pachygenium parvum, Polystachya concreta y Prescottia leptostachya (restringida al estado de Bahía) forman poblaciones pequeñas (<50 individuos). Conclusiones: La flora orquidológica del PNMR Praia do Forte, especialmente las especies antes mencionadas, requiere la atención de los gestores, para implementar posibles acciones de manejo y conservación y evitar su supresión local. Sugerimos mayores acciones de vigilancia en el parque y educación ambiental entre residentes locales y turistas.
