Resumen Antecedentes: El bosque tropical caducifolio constituye zonas con altos niveles de biodiversidad; sin embargo, este ecosistema presente en el municipio de Nocupétaro, Michoacán carece de inventarios florísticos. Preguntas: ¿Qué especies están presentes en el área de estudio? ¿Cuáles especies son endémicas de México y cuántas están en riesgo? ¿Con qué zona tiene mayor afinidad florística? Especies en estudio: Plantas vasculares. Sitio y fechas de estudio: Área de un bosque tropical caducifolio ubicada en el municipio de Nocupétaro, Michoacán, México; septiembre 2016 a noviembre 2017. Métodos: Se realizaron recolectas botánicas en campo. Los especímenes se identificaron con bibliografía especializada. La vegetación se definió con base en la fisonomía y las especies dominantes. Los resultados se comparan con cuatro zonas de bosque tropical caducifolio. Resultados: Se registran 56 familias, 135 géneros, 173 especies y ocho taxa infraespecíficos. Las familias mejor representadas son Fabaceae (34 spp.), Asteraceae (12 spp.), Euphorbiaceae (11 spp.), Apocynaceae (9 spp.), Malvaceae (8 spp.) y Convolvulaceae (7 spp.). Los géneros con más especies son Euphorbia (6), Senna (6), Ipomoea (5) y Bursera (4). Cuarenta y cinco especies son endémicas de México; dos están enlistadas en la NOM-059-SEMARNAT-2010 y tres en la Lista Roja de la IUCN con una categoría de riesgo. El área tiene mayor similitud florística con el cerro La Parotita. Conclusiones: La información generada es la base para otras investigaciones (ecológicas, faunísticas) y resalta la importancia de seguir estudiando y conservando este ecosistema en la región.

Abstract Background: Tropical deciduous forest possesses high levels of biodiversity; however, there is not a complete floristic survey of this ecosystem in the municipality of Nocupétaro, Michoacán. Questions: Which species are present in the study area? Which species are endemic to Mexico and how many are at risk? With which area does it have the greatest floristic affinity? Studied species: Vascular plants. Study site and dates: An area of tropical deciduous forest occurring in the municipality of Nocupétaro, Michoacán, Mexico; September 2016 to November 2017. Methods: Specimens were collected in the field and determined using pertinent specialized literature. The vegetation was defined using physiognomy and dominant species. Results: Fifty-six families, 135 genera, 173 species, and eight infraespecific taxa were registered. The families with more species were Fabaceae (34 spp.), Asteraceae (12 spp.), Euphorbiaceae (11 spp.), Apocynaceae (9 spp.), Malvaceae (8 spp.), and Convolvulaceae (7 spp.). The most speciose genera were Euphorbia (6), Senna (6), Ipomoea (5), and Bursera (4). Forty-five species are endemic to Mexico; two are listed in the NOM-059-SEMARNAT-2010 and three species are included IUCN Red List with a risk category. The area has a greater floristic affinity with the Parotita hill. Conclusions: The information generated is the basis for other research (ecological, fauna) and stand out the importance of continuing to study and conserve this ecosystem in the region.

SUMMARY: The study evaluates the ecosystem services associated with the woodland and shrubland located in the Guajira region of Colombia, characterized as Tropical Dry Forest in the serrania Macuira where communities of the Wayuu native tribe are settled. The open shrubland (OS) and dense shrubland (DS) plant covers were evaluated; three sampling points were selected per cover, in which circular plots with an area of 1,000 m2 were drawn, in each plot, an inventory of the tree component was carried out and the main uses by the community were identified. 20 species and 12 botanical families were found. The species with the greatest dominance in the AA was Prosopis juliflora with an importance value index (IVI) of 157.30 % and in the AD Handroanthus billbergii (IVI 116.81 %); the biodiversity indices did not show statistical differences between the vegetation covers. The carbon storage showed significant statistical differences, the DS accumulated 30.75 t C ha-1 and the OS 12.44 t C ha-1. En relation to CO2 emissions, two scenarios were proposed for the period 2021- 2030: the first, deforestation remains at an annual rate of 0.94 % and emissions from deforestation of 3.72 t CO2-eq ha-1are generated in the OS and 9.20 t CO2-eq ha-1 for the DS. In the second scenario, tree covers are conserved and no emissions are generated from deforestation. 17 useful species were found in the community, of which 16 are used as forage and 13 have medicinal and ethnoveterinary value.

RESUMEN: El estudio evalúa los servicios ecosistémicos asociados a los bosques y matorrales ubicados en la región de La Guajira de Colombia, caracterizados como Bosque Seco Tropical en la Serranía Macuira, donde se asientan comunidades de la tribu nativa Wayúu. Se evaluaron las coberturas vegetales Arbustal Abierto (AA) y Arbustal Denso (AD), se seleccionaron tres puntos de muestreo por cobertura, en los que se trazaron parcelas circulares con un área 1.000 m2, en cada parcela se realizó el inventario del componente arbóreo e identificaron los principales usos por la comunidad. Se hallaron 20 especies y 12 familias botánicas. La especie con mayor dominancia en la AA fue Prosopis juliflora con un Índice de Valor de Importancia (IVI) de 157,30 % y en la AD Handroanthus billbergii (IVI 116,81 %); los índices de biodiversidad no arrojaron diferencias estadísticas entre las coberturas vegetales. El almacenamiento de carbono mostró diferencias estadísticas significativas, la AD acumuló 30,75 t C ha-1 y la AA 12,44 t C ha-1. En relación con las emisiones de CO2 , se plantearon dos escenarios para el período 2021-2030: en el primero, la deforestación se mantiene a una tasa anual de 0,94 % y se generan emisiones por deforestación de 3,72 t CO2-eq ha-1 en el AA y 9,20 t CO2-eq ha-1 para el AD. En el segundo escenario se conservan las coberturas arbóreas y no se generan emisiones por deforestación. Se encontraron 17 especies útiles en la comunidad, de las cuales 16 son empleadas como forraje y 13 presentan valor medicinal y etnoveterinario.

Summary Introduction and aims: The plant species grown in Educational Establishments are diverse, reflecting the customs of the local population. Their presence could contribute to the revaluation of local flora, acting as pedagogical triggers and fulfilling an ornamental function simultaneously. The objectives of this study are to inventory the plant species in recreational spaces of the kindergartens of the Bahía Blanca District and to collect information related to the presence of these species, as well as the general knowledge that managers/teachers have about them. M&M: A floristic census was carried out in recreational spaces of 85 public and private kindergartens. Directors/teachers were surveyed/interviewed to record complementary information about the species and their role in the institution. Results: Two hundred seventy-two species belonging to 86 botanical families were identified. 88% were found to be exotic, and 12% were native, with 1.45% being endemic to Argentina. 100% of all kindergartens that present plants have exotic species, 43% 43% native species and 10% endemic species. The teachers recognize a need for knowledge of the botanical environment and mention an interest in training on the subject. Conclusions: The diversity of plant species in the recreational spaces of kindergartens is high, most of them being exotic. It is important to plan plant species in these institutions so that they can be used as teaching resources.

Resumen Introducción y objetivos: Las especies vegetales cultivadas en Establecimientos Educativos son diversas reflejando el costumbrismo de la población local. Su presencia podría contribuir a la revalorización de la flora local, actuando como disparadores pedagógicos y, a la vez, cumplir una función ornamental. Los objetivos de este estudio son inventariar las especies vegetales en espacios recreativos de los jardines de infantes del Partido de Bahía Blanca y relevar información relacionada con la presencia de dichas especies, así como el conocimiento general que tienen los directivos/docentes sobre las mismas. M&M: Se realizó un censo florístico en 85 establecimientos públicos y privados y se encuestó/entrevistó a la persona responsable a fin de registrar información complementaria en relación a las especies y el rol que cumplen en la institución. Resultados: Se identificaron 272 especies pertenecientes a 86 familias botánicas. Se encontró un 88% de exóticas y 12% de nativas, siendo el 1,45% endémicas de Argentina. El 100% de los jardines de infantes con plantas tienen especies exóticas, el 43% especies nativas y el 10% endémicas. Los docentes reconocen falta de conocimiento del entorno botánico, mencionan interés en capacitarse en el tema. Conclusiones: La diversidad de especies de plantas en los espacios recreativos de los jardines de infantes es alta, siendo en su mayoría exóticas. Es importante una planificación de las especies de plantas en estas instituciones para que puedan ser utilizadas como recursos didácticos.

RESUMEN Los principios bioéticos: beneficencia, no maleficencia, autonomía y justicia, se han analizado detalladamente en las ciencias médicas, sin embargo, se ha descubierto la posibilidad de contextualización en otras ciencias. El estudio propende al abordaje de acciones de protección de los recursos forestales en la finca experimental Andil. Justamente, se parte de la problemática existente entre las acciones antrópicas y las afectaciones a los ecosistemas naturales, donde se provoca anualmente pérdidas cuantiosas de especies y otras en vía en extinción. La bioética como ciencia de la supervivencia se entrelaza con la naturaleza, sin embargo, no hay estudios en Ecuador que revelen esta relación. Se plantea como supuesto hipotético que la aprehensión de los principios bioéticos garantiza la protección de los ecosistemas. El objetivo es analizar la relación entre la bioética y la protección de los recursos forestales de la finca experimental Andil. En la metodología se consideraron, métodos del nivel teórico y empírico, con fundamentos del estadístico - matemático. El principal resultado revela que, en la zona de estudio, sur de Manabí, hay un descenso numérico de especies florísticas y faunísticas, con énfasis en los recursos forestales, que ha provocado mortalidad de otras especies y migración.

ABSTRACT The bioethical principles: beneficence, non-maleficence, autonomy and justice, have been analyzed in detail in the medical sciences, however, the possibility of contextualization in other sciences has been discovered. The study aims to address actions to protect forest resources in the Andil experimental farm. Precisely, it starts from the existing problem between anthropogenic actions and the effects on natural ecosystems, where large losses of species are caused annually and others are on the verge of extinction. Bioethics as a science of survival is intertwined with nature, however, there are no studies in Ecuador that reveal this relationship. It is proposed as a hypothetical assumption that the apprehension of bioethical principles guarantees the protection of ecosystems. The objective is to analyze the relationship between bioethics and the protection of forest resources of the Andil experimental farm. In the methodology, methods at the theoretical and empirical level were considered, with statisticalmathematical foundations. The main result reveals that, in the study area, south of Manabí, there is a numerical decrease in floristic and faunal species, with emphasis on forest resources, which has caused mortality of other species and migration.

Abstract Studies of marine and estuarine red algae (Rhodophyta) are in the early stages in the littoral of the Sian Ka’an Biosphere Reserve, Mexico. The inventory of these organisms was made based on samples obtained from ten sampling during 2009 to 2015 in 22 localities, eight of them in marine and fourteen in estuarine environments. We found 182 species and subspecific taxa of Rhodophyta. The Rhodomelaceae family was the best represented with 65 taxa, followed by Ceramiaceae 13 and Delesseriaceae 12. Of the 182 taxa, 25 are new records Sian Ka’an Biosphere Reserve with Harveylithon rupestre, Spongites fruticulosus, Acrochaetium barbadense, Dasya harveyi, Chondria pumila, Spermothamnion repens, Metapeyssonnelia milleporoides and M. tangerina being new records for the Mexican Caribbean. Of the 182 species, 119 of them are epiphytes, most of them, 54, grew exclusively on other macroalgae, 29 on mangrove roots and 8 on Thalassia leaves. The floristic list is accompanied by data on seasonality, reproduction, habitat, and environment. Species diversity was compared between the winter rains, dry and rainy seasons during the period study. The Rhodophyta of the Sian Ka’an Biosphere Reserve is tropical, and the greatest diversity was found in the marine environment with 83 taxa and during the winter rains with 132.

Abstract Assessing diversity allows us to know the general state of ecological systems, the impact of climate change, forest management and other anthropic activities, and has been used for practical purposes of conservation, monitoring and management of forests. The objective of the study was to analyze the structure, diversity and similarity of the tree stratum of Pseudotsuga menziesii forests in Mexico, a species listed in NOM-059-SEMARNAT-2010, whose areas are considered of High Conservation Value. The present study included 11 of the 14 states where this species is distributed in Mexico. Information from 28 Pseudotsuga communities was analyzed and processed, obtained from the National Forest and Soil Inventory, research works and own information; horizontal structure was determined with the Importance Value Index (IVI), diversity with the Shannon-Wiener (H') and Pielou (J) index, significant differences in diversity were determined with the Hutcheson's t-test, and floristic similarity was obtained with the Morisita-Horn index. At the national level, 9 families, 14 genera and 45 species were recorded, the IVI of Pseudotsuga fluctuates between 20.77 and 53.33; H' values generally indicate low diversity (<2.00) and high J-equity (>0.70). The Morisita index presents three groupings corresponding to the physiographic provinces Sierra Madre Occidental, Sierra Madre Oriental and Faja Volcánica Transmexicana, and reflects a high similarity within each province and medium to low similarity between regions. This work will contribute to the development of management strategies for monitoring and conservation in these forests.

El objetivo del estudio fue analizar la estructura, diversidad y similitud del estrato arbóreo de los bosques de Pseudotsuga menziesii en México, especie enlistada en la NOM-059-SEMARNAT-2010, cuyas áreas son consideradas de Alto Valor de Conservación. El presente estudio comprendió 11 de los 14 estados donde se distribuye esta especie en México. Se analizó y procesó información de 28 comunidades de Pseudotsuga, obtenidas del Inventario Nacional Forestal y de Suelos, trabajos de investigación e información propia; la estructura horizontal se determinó con el Índice de Valor de Importancia (IVI), la diversidad con el índice de Shannon-Wiener (H’) y Pielou (J), se determinaron las diferencias significativas en diversidad de H’ con la prueba de t de Hutcheson, y la similitud florística se obtuvo con el índice de Morisita-Horn. A nivel nacional se registraron 9 familias, 14 géneros y 45 especies, el IVI de Pseudotsuga fluctúa entre 20.77 a 53.33; los valores de H’ en general indican baja diversidad (<2.00) y alta equidad J (>0.70). El índice de Morisita presenta tres agrupaciones correspondientes a las provincias fisiográficas Sierra Madre Occidental, Sierra Madre Oriental y Faja Volcánica Transmexicana, y refleja una alta semejanza dentro de cada provincia y media a baja entre regiones. El presente trabajo coadyuvará al desarrollo de estrategias de manejo en estos bosques para su monitoreo y conservación.

Abstract Melastomataceae is one of the richest families in Brazil, with 1,436 species, 158 occurring in the state of Paraná. Many of the species are pioneers and zoochoric, essential for regeneration and floristic composition of the Atlantic Forest, which is the phytogeographic domain covering the Iguaçu National Park (ParNa Iguaçu). We present the floristic inventory of Melastomataceae of ParNa Iguaçu. Three areas in the park were sampled from May 2019 to March 2020, where two are covered with Seasonal Semideciduous Forest (SSF), and the other in a transition between SSF and Mixed Ombrophilous Forest (MOF). Seventeen species of Melastomataceae in four genera were recorded: Miconia (14 spp.), Acisanthera, Chaetogastra, and Pleroma (with only one species each). Seven species occur in the two vegetation types in ParNa Iguaçu, while six occur only in MOF and four only in SSF. Of the 17 species, six are endemic to Brazil, four of which occur only in the south and southeast regions of the country. This study registers nine new records for the ParNa Iguaçu. Furthermore, the Miconia leaeichleri was collected for the first time in the western region of Paraná, which suggests the necessity for more collection efforts in the western region of the state.

Resumo Melastomataceae é uma das famílias com maior riqueza de espécies no Brasil, formada por 1.436 espécies, com 158 ocorrendo no estado do Paraná. Muitas espécies são pioneiras e zoocóricas, sendo essenciais na regeneração e composição florística na Mata Atlântica, que é a cobertura do domínio fitogeográfico do Parque Nacional do Iguaçu (ParNa Iguaçu). Nõs apresentamos o inventário florístico de Melastomataceae do Parque Nacional do Iguaçu. Foram amostradas três áreas do Parque no período de 2019 a fevereiro de 2020, onde duas são cobertas por Floresta Estacional Semidecidual (FES) e a outra em transição entre FES e Floresta Ombrófila Mista (FOM). Dezessete espécies de Melastomataceae distribuídas em quatro gêneros foram registrados: Miconia (com 14 spp.), Acisanthera, Chaetogastra e Pleroma (com apenas uma espécie cada). Sete espécies ocorrem nos dois tipos de vegetação do ParNa Iguaçu, enquanto seis ocorrem apenas em FOM e quatro apenas em FES. Das 17 espécies encontradas, seis são endêmicas do Brasil e quatro ocorrem somente nas regiões sul e sudeste do país. Este estudo registra nove novos registros para o ParNa Iguaçu. Além disso, Miconia leaeichleri foi coletada pela primeira vez na região oeste dos estado do Paraná, o que sugere a necessidade de um maior esforço de coleta na região oeste do estado. 1436 1 436 1.43 15 Paraná zoocóricas Atlântica .

ABSTRACT Ludwigia L. is the largest genus of Onagraceae, despite its representativeness in Brazil, it has been understudied, leading to misidentified specimens in herbaria. This study provides an inventory of Ludwigia species occurring in the State of Piauí. Specimens of Onagraceae were analyzed in the CSTR, HUEFS, RB, and TEPB herbaria, as well as digitized specimens available on speciesLink and Reflora. Identification was based on specialized literature. Ten species were recognized: Ludwigia affinis (DC.) H.Hara, L. elegans (Cambess.) H.Hara, L. erecta (L.) H.Hara, L. helminthorrhiza (Mart.) H.Hara, L. hyssopifolia (G. Don) Exell, L. leptocarpa (Nutt.) H.Hara, L. nervosa (Poir.) H. Hara, L. octovalvis (Jacq.) P.H.Raven, L. sedoides (Bonpl.) H.Hara, and L. tomentosa (Cambess.) H.

Resumo A Serra do Ibitipoca ocorre no sudeste do estado de Minas Gerais, sudeste do Brasil, e inclui um mosaico de diferentes tipos de vegetação, como parte do domínio da Mata Atlântica. Tal heterogeneidade é resultado da ocorrência de diversos ecótonos na região, considerados áreas de amortecimento essenciais para manutenção da biodiversidade e estrutura de ecossistemas adjacentes. Dada a importância destes ambientes para conservação da biodiversidade, inventários florísticos são importantes para catalogar a riqueza de plantas em áreas naturais, onde espécies e paisagens têm sido destruídas, especialmente nas últimas décadas. Para contribuir com o aumento do conhecimento sobre a Flora vascular na Serra do Ibitipoca, um inventário florístico foi conduzido em áreas privadas adjacentes ao Parque Estadual do Ibitipoca. As descobertas mais relevantes do presente estudo incluem: caracterização dos diferentes tipos de vegetação, 17 novos registros para a Flora de Minas Gerais, coleta de 288 espécies nunca registradas para o parque (80% de dissimilaridade – especialmente devido à ocorrência e tamanho de diferentes fitofisionomias entre as áreas) e presença de 31 espécies ameaçadas.

Abstract The Ibitipoca Mountains occur in southeastern Minas Gerais state, Southeast Brazil, and includes a mosaic of different vegetation types, as part of the Atlantic Forest domain. Such heterogeneity results in the occurrence of several ecotones in the region, considered essential buffer zones for maintaining biodiversity and structure among adjacent ecosystems. Given the importance of these environments for biodiversity conservation, floristic surveys are important to catalogue plant richness in natural areas, where species and landscapes have been destroyed, especially over the last decades. To contribute to increase the knowledge on the vascular Flora in the Ibitipoca Mountains, a floristic inventory was undertaken in private properties located in the boundaries of “Parque Estadual do Ibitipoca” (Ibitipoca State Park). Relevant findings of the present study include: characterization of the different vegetation types, 17 new records for the Flora of Minas Gerais, collection of 288 species never recorded in the state park (80% dissimilarity – especially due to the occurrence and size of different phytophysiognomies between these areas) and presence of 31 threatened species.

ABSTRACT The Brazilian Pampa constitutes a grassland-forest vegetation mosaic, home to a high richness of species, including vascular plants dispersed by spores. Our aim was to conduct an inventory of ferns and lycophytes in a fragment of Pampa, located at Fazenda Estância da Quinta in the municipality of Rio Pardo, Estado do Rio Grande do Sul. The species were collected and deposited in the Herbarium of the University of Caxias do Sul (HUCS). Ecological, geographic and conservation attributes of the species were recorded in the field and through bibliographic searches. The inventory resulted in the recognition of 46 species of ferns and one lycophyte (Isoetes weberi Herter), belonging to 13 families. The terrestrial habit (51%) was predominant, as well as the preferential occurrence within forest fragments (66%). Two species are on the Red List of Threatened Species.

RESUMEN Los bosques montanos se encuentran en un rango altitudinal entre 800 y 3500 m snm, conservan una importante diversidad de especies arbóreas y altos niveles de endemismos. Muchos de estos bosques están siendo convertidos a otros usos de tierra y en algunos casos ocurren procesos sucesionales que permiten el establecimiento de bosques secundarios. Con el fin de evaluar la contribución florística de estos bosques montanos secundarios a la flora arbórea de la región de la Selva Central del Perú, se analizó la composición florística y la diversidad arbórea en dos bosques secundarios ubicados en la provincia de Chanchamayo. Para ello, se instalaron dos parcelas per- manentes de monitoreo de vegetación, siendo estas la Parcela Puyu Sacha Bosque Secundario (P-PS) de 1 ha ubicada en un bosque montano a 2060 m snm, donde se registraron 638 individuos, 52 especies, 37 géneros y 28 familias botánicas, y la Parce- la Génova Bosque Secundario 2 (P-GS2) de 0,6 ha ubicada en un bosque premontano a 1040 m snm, donde se registraron 242 individuos, 34 especies, 32 géneros y 21 familias botánicas. En P-PS (estrato montano entre 1500 y 3500 m snm) las familias más abundantes fueron Urticaceae, Actinidiaceae, Melastomataceae, Cordiaceae y Rubiaceae; y las especies más abundantes fueron Cordia cylindristachya (Ruiz & Pav.) Roem. & Schult., Miconia aff. crassistigma Cogn., Saurauia biserrata (Ruiz & Pav.) Spreng., Cecropia angustifolia Trécul, Cecropia sp.2 y Saurauia glabra (Ruiz & Pav.) Soejarto. En P-GS2 (estrato premontano entre 800 y 1500 m snm) las familias más abundantes fueron Euphorbiaceae, Fabaceae, Cannabaceae, Piperaceae y Urticaceae; y las especies más abundantes fueron Sapium glandulosum (L.) Morong, Trema mi- crantha (L.) Blume, Cecropia polystachya Trécul, Erythrina ulei Harms y Piper aduncum L. Ambas parcelas presentaron bajos niveles de diversidad debido a que se ubican sobre bosques secundarios que en el pasado tuvieron intervenciones antrópicas.

ABSTRACT Montane forests are found in an altitudinal range between 800 and 3500 m asl and conserve an important diversity of tree species and high levels of endemism. Many of these forests are being converted to other land uses and, in some cases, successional processes are occurring that allow the establishment of secondary forests. In order to evaluate the floristic contribution of these secondary montane forests to the arboreal flora of the Selva Central region of Peru, we analyzed the floristic composition and tree diversity in two secondary forests located in the province of Chanchamayo. For this purpose, two permanent vegetation monitoring plots were installed, the Puyu Sacha Secondary Forest Plot (P-PS) of 1 ha located in a montane forest at 2060 m asl, where 638 individuals, 52 species, 37 genera and 28 botanical families were recorded, and the Genova Secondary Forest 2 Plot (P-GS2) of 0.6 ha located in a premontane forest at 1040 m asl, where 242 individuals, 34 species, 32 genera and 21 botanical families were recorded. In P-PS (montane stratum between 1500 and 3500 m asl) the most abundant families were Urticaceae, Actinidiaceae, Melastomataceae, Cordiace- ae and Rubiaceae; and the most abundant species were Cordia cylindristachya (Ruiz & Pav.) Roem. & Schult., Miconia aff. crassistigma Cogn., Saurauia biserrata (Ruiz & Pav.) Spreng., Cecropia angustifolia Trécul, Cecropia sp.2 and Saurauia glabra (Ruiz & Pav.) Soejarto. In P-GS2 (premontane stratum between 800 and 1500 m asl) the most abundant families were Euphorbiaceae, Fabaceae, Cannabaceae, Piperaceae and Urticaceae; and the most abundant species were Sapium glandulosum (L.) Morong, Trema micrantha (L.) Blume, Cecropia polystachya Trécul, Erythrina ulei Harms and Piper aduncum L. Both plots showed low levels of diversity because they are located in secondary forests that in the past had anthropic interventions.

Resumen: En | Texto: En | PDF: En

Abstract Brazilian veredas are hygrophilous communities with high species diversity, featuring many floristic studies but a still incipient number of faunistic studies. In the present study, we conducted an inventory of insect galls in four different veredas located in the Northern region of Minas Gerais, Brazil. Overall, we found 75 gall morphotypes, distributed across 50 host species representing 37 plant genera and 22 families. Fabaceae was the plant family with the greatest number of insect gall morphotypes (n = 21), followed by Malpighiaceae (n = 10). The plant genera that supported the highest diversity of insect galls were Copaifera (n = 8) and Byrsomima (n = 5). The plant species Copaifera oblongifolia (n = 6) and Anacardium humile (n = 4) exhibited the highest richness of insect galls. The leaves were the most attacked organs (89% of all galls). Most morphotypes are glabrous (83%), green (69%) and lenticular (60%). The taxa of gall-inducing insects were identified for 46 morphotypes (80%), and were recorded inducers from the orders Diptera, Lepidoptera, and Hymenoptera. Cecidomyiidae (Diptera) was the most representative galling group, with 42 morphotypes, making up 93.3% of the recorded inducers. Among the sampled veredas areas, the Vereda do Peruaçu presented the highest richness of insect gall morphotypes and host plant species. The faunistic similarity was higher in the Pedras and Tiririca veredas, followed by Almescla and Peruaçu veredas. This is the first systematic inventory of insect galls and their host plant in Brazilian veredas. The diversity of insect galls in the studied veredas is relatively high when compared to other Brazilian Cerrado vegetation types. study Gerais Brazil Overall 7 5 3 2 families n 21, 21 , 21) 10. 10 . 10) 8 5. 5) 6 4 89% 89 (89 galls) 83%, 83 83% (83%) 69% 69 (69% 60%. 60 60% (60%) gallinducing inducing 80%, 80 80% (80%) Diptera Lepidoptera Hymenoptera (Diptera group 933 93 93.3 areas types 1 (8 (83% (69 (60% (80% 9 93.

Abstract Asteraceae is highly diverse in the Atlantic Forest, especially in montane environments. The early-diverging tribes within Asteraceae are of particular interest because of their great representation in Brazil and unique features within the family. Thus, a floristic inventory and systematic treatment of these basal grade in Caparaó National Park, an important remnant of Atlantic Forest that has been highlighted for its diversity and endemism, were undertaken. The study was conducted by examining specimens from representative collections of Caparaó and a field expedition. A total of 15 species were found, representing six genera and four tribes, with Mutisieae and Nassauvieae being the most representatives. Six of the species have restricted distributions, either to Brazil (3 spp.), the Atlantic Forest (2) or Caparaó mountain (Mutisia lutzii). Three new records were documented for the park, namely Chaptalia integerrima, Moquiniastrum polymorphum and Mutisia coccinea. Floristic inventories and systematic treatments can make great contributions to science by bringing a better understanding our biodiversity and providing relevant information about flora for the conservation of priority areas. environments earlydiverging early diverging family Thus Park endemism undertaken expedition 1 found representatives distributions 3 ( spp., spp spp. , spp.) 2 (2 lutzii. lutzii . lutzii) park integerrima coccinea areas

ABSTRACT We discuss the importance of fern and lycophyte species in the Atlantic Forest ecosystem as well as the need for floristic inventories to understand their distribution and conservation status. We focus on the Serra do Papagaio region in southeastern Brazil, which is known for its high plant diversity but lacks comprehensive inventories of ferns and lycophytes. In this study, we conducted a floristic inventory of Serra do Papagaio and identified 172 fern and 29 lycophyte species. Our findings reveal 21 threatened species and two new records for Minas Gerais State. Additionally, we compared the floristic composition of Serra do Papagaio with that of other areas within the Atlantic Forest using non-metric multidimensional scaling (NMDS) and generalized dissimilarity modeling (GDM) analyses. The results highlight distinct clusters of areas based on elevation and geographic location. We emphasize the need for further sampling and conservation efforts in Serra do Papagaio as well as provide valuable insights into the drivers of fern and lycophyte diversity in the Atlantic Forest. status Brazil lycophytes study 17 2 State Additionally nonmetric non metric NMDS (NMDS GDM (GDM analyses location 1

Abstract We aimed to characterize the adult and regenerating tree components and their relationships with soil characteristics of a native vegetation remnant in Cuiabá, Mato Grosso, Brazil. The area of the fragment is stratified into “dry area” (lithic neosoil) and “damp area” (gleisoil). We conducted a forest inventory with a random distribution of 25 parcels. We analyzed the physical and chemical components of the soil. We evaluated the vegetation's horizontal structure, diversity, and sample sufficiency using the Bootstrap richness estimator. We classified the species according to dispersal syndrome and ecological group. Overall, we found 93 species in the adult layer and 70 species in the regenerating layer. The similarity dendrograms based on the two evaluated indices demonstrated the existence of the two initially stratified environments in both strata. The IndVal (%) indicated that the set of indicator species differed between the strata. Thereby, the fragment is in an intermediate stage of successional progression. PCA showed that plots in the wet area had higher pH values and Ca, Zn, and Fe levels, while plots in the dry area did not clearly distinguish, varying in terms of K, B, and organic matter content. In CCA, a set of species that occurred exclusively in the damp area showed a strong relationship with the analyzed variables. The area is a diverse ecosystem that efficiently provides ecosystem services to society and should be the subject of long-term conservation and research.

Resumo Nós objetivamos caracterizar os componentes de arbóreos adultos e em regeneração, bem como suas relações com as características do solo de um remanescente de vegetação nativa em Cuiabá, Mato Grosso, Brasil. A área do fragmento foi estratificada em “área seca” (neossolo lítico) e “área úmida” (gleissolo). Realizamos um inventário florestal com uma distribuição aleatória de 25 parcelas. Analisamos os componentes físicos e químicos do solo. Avaliamos a estrutura horizontal da vegetação, além da diversidade e suficiência amostral por meio do estimador de riqueza Bootstrap. Classificamos as espécies de acordo com a síndrome de dispersão e o grupo ecológico. No geral, encontramos 93 espécies no extrato adulto e 70 espécies no extrato regenerante. Os dendrogramas de similaridade com base nos dois índices avaliados demonstraram a existência dos dois ambientes inicialmente estratificados em ambos os extratos. O Índice de Valor de Indicação (IndVal %) indicou que o conjunto de espécies indicadoras diferiu entre os extratos. Assim, o fragmento encontra-se em um estágio intermediário de progressão sucessional. A Análise de Componentes Principais (PCA) mostrou que as parcelas na área úmida apresentavam valores de pH mais elevados e níveis elevados de cálcio (Ca), zinco (Zn) e ferro (Fe), enquanto as parcelas na área seca não se distinguiram claramente, variando em termos de potássio (K), boro (B) e teor de matéria orgânica. Na Análise de Correspondência Canônica (CCA), um conjunto de espécies que ocorreu exclusivamente na área úmida mostrou uma forte relação com as variáveis analisadas. A área é um ecossistema diversificado que fornece eficientemente serviços ecossistêmicos à sociedade e deve ser objeto de conservação e pesquisa de longo prazo. regeneração Cuiabá Grosso Brasil neossolo lítico gleissolo. gleissolo .
