Resumen (Objetivo). Se evaluó el manglar de Chacarita en el Pacífico Central de Costa Rica, a través de la composición florística y las poblaciones de moluscos asociados de interés comercial, con el fin de proponer actividades de aprovechamiento sustentables en el manglar. (Metodología). Mensualmente y durante un año, se realizaron visitas al área de estudio, con el propósito de establecer una base florística de árboles de mangle y medir el almacenamiento de carbono en el lugar, además, de recolectar moluscos bivalvos para analizar el estado de las poblaciones, con base en las abundancias de organismos hallados y otras características como las longitudes y la masa de estos. En los mangles, se obtuvo el diámetro de la altura de pecho (DAP en cm), la altura (m), el índice de valor de importancia (IVI) y las reservas de carbono (Mg C·ha-1). En cuanto a los moluscos, se examinaron cuatro especies de interés comercial, evaluando la longitud (cm), la masa (g) y el índice gonadosomático. Finalmente, se realizaron valoraciones económicas de los datos obtenidos en el manglar, del turismo e información histórica de pesca para el acopio de Chacarita. (Resultados). Se hallaron cinco especies de mangles, Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avicennia germinans y Pelliciera rhizophorae; P. rhizophorae fue la de mayor índice de valor de importancia. Se obtuvo un almacenamiento de carbono equivalente a 78.49 Mg C·ha-1. Se contabilizaron 357 organismos, de los cuales el 18 % correspondió a Anadara similis, 37.5 % a Anadara tuberculosa, 41.46 % a Leukoma spp. y 3.08 % a Mytella guyanensis. Tomando en cuenta el valor económico de las reservas de carbono y los moluscos bivalvos presentes en los muestreos, se obtuvieron valoraciones económicas de 9812.63 USD·ha-1 y 28 USD·ha-1, respectivamente. (Conclusiones). Las bajas densidades poblacionales de moluscos, especialmente del género Anadara, hacen necesario establecer medidas de gestión que permitan recuperar las poblaciones de estos. La presente investigación propone actividades de aprovechamiento sustentables, como turismo comunitario con fines educativos y culturales.

Resumo (Objetivo). O mangue de Chacarita, no Pacífico Central da Costa Rica, foi avaliado por meio da composição florística e das populações de moluscos associados de interesse comercial, com o objetivo de propor atividades de uso sustentável no mangue. (Metodologia). Foram feitas visitas mensais à área de estudo durante um ano para estabelecer uma base florística de árvores do mangue e medir o armazenamento de carbono no local, bem como para coletar moluscos bivalves para analisar o status das populações, com base na abundância de organismos encontrados e em outras características, como comprimento e massa de tais organismos. Nos manguezais, foram obtidos o diâmetro à altura do peito (DAP em cm), a altura (m), o índice de valor de importância (IVI) e as reservas de carbono (Mg C-ha-1). No que diz respeito aos moluscos, foram examinadas quatro espécies de interesse comercial., avaliando o comprimento (cm), a massa (g) e o índice gonadossomático. Por fim, foram feitas avaliações econômicas de dados de mangue, turismo e informações históricas de pesca para a coleção Chacarita. (Resultados). Foram encontradas cinco espécies de mangue, Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avicennia germinans e Pelliciera rhizophorae; a P. rhizophorae apresentou o índice de valor de importância mais alto. Foi obtido um armazenamento de carbono equivalente a 78.49 Mg C-ha-1. Foram calculados um total de 357 organismos, dos quais 18% correspondeu a Anadara similis, 37.5% Anadara tuberculosa, 41.46% Leukoma spp. e 3.08% Mytella guyanensis. Levando em conta o valor econômico das reservas de carbono e dos moluscos bivalves presentes nas amostras, foram obtidas avaliações econômicas de US$ 9812.63 ha-1 e US$ 28 ha-1, respectivamente. (Conclusões). As baixas densidades populacionais de moluscos, especialmente do gênero Anadara tornam necessário o estabelecimento de medidas de manejo para permitir a recuperação dessas populações. Esta pesquisa propõe atividades de uso sustentável, como o turismo comunitário para fins educacionais e culturais.

Abstract (Objective). The floristic composition and populations of associated molluscs of commercial interest of the Chacarita mangrove forest on the Central Pacific of Costa Rica were evaluated to guide proposals for sustainable exploitation activities in the mangrove forest. (Methodology). Monthly visits to the study area were conducted for one year to establish a floristic baseline of mangrove trees and measure carbon storage. Additionally, bivalve molluscs were collected to analyze the state of their populations based on the abundances of organisms found, as well as other characteristics such as length and mass. Data regarding the mangrove trees included their diameter at breast height (DBH, cm), height (m), importance value index (IVI), and carbon reserves (Mg C·ha-1). Four mollusc species of commercial interest were analyzed, using data on their length (cm), weight (g), and gonodosomatic index. Economic evaluations were also conducted using data obtained from the mangrove forest, as well as tourism and historical fishing data for the collection of Chacarita. (Results). Five species of mangroves were identified: Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avice germinans, and Pelliciera rhizophorae, while P. rhizophorae had the highest importance value index. The study revealed a carbon storage equivalent to 78.49 Mg C·ha-1. A total of 357 organisms were counted, with Anadara similis accounting for 18% of the total count, followed by Anadara tuberculosa (37.5%), Leukoma spp. (41.46%), and Mytella guyanensis (3.08%). When considering the economic value of carbon stocks and the bivalve molluscs obtained from the samples, economic valuations of 9,812.63 USD·ha-1 and 28 USD·ha-1 were determined, respectively. (Conclusions). The low population densities of molluscs, particularly those belonging to the Anadara genus, necessitate the establishment of management measures to facilitate the recovery of these mollusk populations. This research proposes sustainable use activities such as community tourism for educational and cultural purposes.

Resumen: En Es | Texto: En Es | PDF: En | PDF: Es

Abstract Introduction: A recent revision of the generic classification of the Trochilidae based on DNA sequences revealed many inconsistencies with the current generic classification, largely based on plumage characters subject to homoplasy, especially in the Trochilini, the largest tribe. A thorough generic reorganization brought the classification into accord with the phylogeny, but due to lack of genetic data, two species remained unclassified. One of these was the Mangrove Hummingbird, “Amazilia” boucardi, endemic to Costa Rica and included in the IUCN red list of threatened species. Objective: To obtain molecular evidence to clarify the generic relationships of “A.” boucardi. Methods: We isolated DNA from tissues of this species and amplified 4 nuclear and 4 mitochondrial fragments and compared these with homologous fragments from 56 species in the Trochilini, constructing phylogenetic trees with maximum likelihood and Bayesian methods. Results: Our phylogenetic analyses confirmed the placement of boucardi in the Trochilini and definitely excluded it from Amazilia but placed it with high confidence in the genus Chrysuronia Bonaparte, 1850, within which its closest relative is C. coeruleogularis, which also inhabits mangroves. Conclusions: Our genetic data based on nuclear and mitochondrial regions clearly indicate the relationship of A. boucardi and L. coeruleogularis. Moreover, it is also supported by their habitat distribution in the mangroves of the Pacific coast of Costa Rica and Western Panama. Therefore, we suggested to exclude A. boucardi as “incertae sedis”.

Resumen Introducción: Una revisión reciente de la clasificación de la familia Trochilidae con base en secuencias de ADN demostró muchas incongruencias con la clasificación genérica previa, que había sido hecho con base en caracteres del plumaje muy sujetos a homoplasia, especialmente en la tribu más grande, Trochillini. Una reorganización de los géneros logró llevar su clasificación genérica a la concordancia con la filogenia, pero debido a la ausencia de datos genéticos, dos especies permanecieron sin clasificar. Una de estas fue el colibrí de manglar Amazilia boucardi, una especie endémica de Costa Rica, considerada como amenazada en la lista roja de la UICN. Objetivo: Obtener evidencia molecular para esclarecer las relaciones genéricas de A. boucardi. Métodos: Se aisló ADN de tejidos de esta especie y se amplificaron 4 fragmentos de ADN del núcleo y 5 de la mitocondria, y se compararon con fragmentos homólogos de 56 especies en la tribu Trochillini, generando árboles filogenéticos con métodos de máxima verosimilitud y bayesiano. Resultados: Los análisis filogénticos obtenidos confirmaron la ubicación de boucardi en Trochilini y definitivamente la excluyó del género Amazilia, pero la ubicó con un alto grado de confianza en el género Chrysuronia Bonaparte, 1850, dentro los cuales su pariente más cercano es C. coeruleogularis, que también habita manglares. Conclusiones: Nuestros datos genéticos basados en regiones nucleares y mitocondriales indican claramente la relación entre A. boucardi and L. coeruleogularis. Es más, lo anterior se sustenta por su distribución en los manglares de la costa Pacífica de Costa Rica y oeste de Panamá. Por lo tanto, sugerimos excluir a A. boucardi como “incertae sedis”.

Resumen. Los datos de campo obtenidos de los inventarios forestales, principalmente área basal y densidad de fustes, son relevantes para el análisis de la biomasa aérea y la fragmentación forestal. Debido al suelo inundado, el trabajo de campo en los bosques de manglar requiere mucho tiempo y es complicado. Dado que los manglares son sensibles a los efectos del cambio climático, la selección de un método de campo ideal es de suma importancia. Con este fin, analizamos 4 clases de manglares: Rhizophora mangle (RM), Laguncularia racemosa (LR), Avicennia germinans (AG) y AG arbustivo. Georreferenciamos y contamos todos los fustes de mangle dentro de 4 parcelas cuadradas de 0.04 ha (20 × 20 m). Analizamos 3 áreas circulares y el método del punto cuadrante central (PCQM) basado en las parcelas cuadradas originales. Dependiendo de la clase de mangle, el PCQM sobreestimó el área basal hasta en un 34% y la densidad de fustes en un 21%. Los 3 muestreos en parcelas circulares subestimaron el área basal entre -1% y -29% y la densidad de fustes entre -3% y -25%. Basándonos en los resultados, sugerimos utilizar una parcela circular de 0.04 ha (r = 11.28 m) en bosques menos densos (RM y AG) y una parcela circular de 0.015 ha (r = 6.9 m) en densidades superiores a 3,500 fustes/ha (LR y AG arbustivo). Las ventajas de utilizar las parcelas circulares sobre el método PCQM son que los inventarios de mangle pueden cuantificarse rápidamente y no requieren un número mínimo de puntos de muestreo.

Abstract. The data obtained from field-based forest inventories, mainly basal area and stem density, are relevant for the analysis of aboveground biomass and forest fragmentation. Due to its persistently flooded ground, fieldwork in mangrove forests is time-consuming and complicated. Since mangroves are sensitive to the effects of climate change, selecting a reliable field method is of utmost importance. To this end, we analyzed 4 mangrove classes: Rhizophora mangle (RM), Laguncularia racemosa (LR), Avicennia germinans (AG), and AG shrub. We georeferenced and counted all mangrove stems within four 0.04 ha (20 × 20 m square). We analyzed data from 3 circular area plots and the plotless point-centered quarter method (PCQM) based on the original square plots. Depending on the mangrove class, PCQM overestimated basal area by up to 34% and stem density by 21%. The 3 circular plot surveys underestimated basal area from -1% to -29% and stem density from -3 to -25%. Based on the results, we suggest using a circular plot of 0.04 ha (r = 11.28 m) in less dense forests (RM and AG) and a circular plot of 0.015 ha (r = 6.9 m) with forest densities greater than 3,500 stems/ha (LR and AG shrub). The advantages of using the circular plot approach over PCQM are that mangrove inventories can be quantified quickly and do not require a minimum number of sampling points.

Abstract This contribution identifies the socio-environmental dynamics that development policies have generated on community mangroves in three key moments of Mexican history: the 1917 Constitution, the industrialization of the 1950s, and the 1985 neoliberal reforms. Through eight case studies and 180 semi-structured interviews, a conceptual input shapes three scenarios (community, touristified and conserved mangroves) and fifteen categories that synthesize these dynamics. Mangroves are going through a continuous crisis that is arguably provoked by development policies that neglect local institutions and impoverish local inhabitants. This article offers alternatives that the federal government could take into consideration to manage these areas more effectively at the environmental and territorial levels.

Resumen Este aporte identifica las dinámicas socioambientales que las políticas de desarrollo han generado sobre los manglares comunitarios en tres momentos clave de la historia mexicana: la Constitución de 1917, la industrialización de la década de 1950 y las reformas neoliberales de 1985. Mediante ocho estudios de caso y 180 entrevistas semiestructuradas, se elaboró un insumo conceptual de tres escenarios (manglares comunitarios, turistificados y conservados) y quince categorías que sintetizan estas dinámicas. Los manglares atraviesan una crisis histórica que provocarían las políticas de desarrollo que no atienden si no que debilitarían a las instituciones locales y empobrecerían a los habitantes de las localidades. Los autores ofrecen recomendaciones para que la gestión del gobierno federal sea más efectiva a nivel ambiental y territorial.

ABSTRACT Astructural, morphological and environmental description of tea mangrove individuals (genus Pelliciera) is presented. The specimens studied were found in eight sectors of Caño Salado which is a preservation zone in the Cispatá Bay Management Plan, using monitoring plots of 500 m2 (20 m x 25 m). The reported samples presented characters consistent with the recently redescribed species Pelliciera benthamii, found in forest relicts with a disperse spatial distribution. Reports of this species in the Cispatá bay are of great importance for the knowledge of the Colombian mangroves and to generate conservation and restoration initiatives that will have a positive impact on the populations of Pelliciera mangrove trees currently in state of threat.

RESUMEN Se presenta una descripción estructural, morfológica y ambiental de individuos de mangle de té (genero Pelliciera). Los especímenes estudiados fueron encontrados en ocho sectores de Caño Salado, que es una zona de preservación en el plan de manejo de la bahía de Cispatá, en parcelas de monitoreo de 500 m2 (20 m x 25 m). Las muestras registradas presentaron caracteres consistentes con la especie recientemente descrita Pelliciera benthamii encontrada en relictos de bosque con una distribución espacial dispersa. Los registros de esta especie en Cispatá son de gran importancia para el conocimiento de los manglares colombianos y para generar iniciativas de conservación y restauración que impacten positivamente las poblaciones de Pelliciera, actualmente en estado de amenaza.

ABSTRACT Overfishing, industrial fishing and climate change generate impacts that affect the marine fishery resource, the main source of income and food for coastal populations of artisanal fishers. The creation of conditions that increase the adaptive capacity of fishers will decrease their vulnerability to impacts. This research proposes to determine an Exclusive Zone for Artisanal Fishing-ZEPA as a strategy for sustainable management of fishery resources and climate adaptation for artisanal fishers in the study area. Marxan was used to identify three scenarios for the location of the ZEPA and participatory mapping was carried out with fishers to obtain the fourth scenario. High similarity was found between scenarios 2 and 4, which shows that the scientific (Marxan) and participatory (population) approaches coincide in the location of the ZEPA. The final ZEPA was located in the coastal marine zone of the municipalities of Tumaco and Francisco Pizarro, with a total area of 2,008 km2. Included important conservation targets for artisanal fisheries such as artisanal fishing grounds, ecosystems (mangroves, beaches and estuaries), areas of occurrence of species (seerfish, snappers, sea bass, piangua, marmoset shrimp) among others. More than 80 % of the fishers agreed that the strategy would help reduce their vulnerability to threats such as climatic phenomena, overfishing, pollution, among others. The contribution to climate change adaptation of the study area’s population is highlighted.

RESUMEN La sobrepesca, la pesca industrial y el cambio climático generan impactos que afectan al recurso pesquero marino, la principal fuente de ingreso y alimento de las poblaciones costeras de pescadores artesanales. La creación de condiciones que incrementen la capacidad de adaptación de los pescadores disminuirá su vulnerabilidad a los impactos. Esta investigación propone determinar una Zona Exclusiva de Pesca Artesanal-ZEPA como estrategia de manejo sostenible de los recursos pesqueros y de adaptación climática para los pescadores artesanales del área de estudio. Se utilizó el programa Marxan para identificar tres escenarios para la ubicación de la ZEPA y se realizó una cartografía participativa con pescadores para obtener el cuarto escenario. Se encontró similitud alta entre el escenario 2 y 4, lo que muestra que el enfoque científico (Marxan) y participativo (población) coinciden en la ubicación de ZEPA. La ZEPA definitiva se ubicó en la zona marino costera de los municipios de Tumaco y Francisco Pizarro, con un área total de 2 008 km2. Incluyó objetos de conservación importantes para la pesca artesanal como caladeros de pesca artesanal, ecosistemas (manglares, playas y estuarios), áreas de ocurrencia de especies (sierra, pargos, corvina, piangua, camarón tití), entre otros. Se identificó que más de 80 % de los pescadores estuvo de acuerdo en que la estrategia le aportaría a reducir su vulnerabilidad frente a amenazas como fenómenos climáticos, sobrepesca, contaminación, entre otros. Se resalta la contribución a la adaptación al cambio climático de la población del área de estudio.

Resumen: En | Texto: En | PDF: En

Abstract The exploited mangrove crab Ucides cordatus, an important ecosystem engineer in South American mangroves, has a biphasic lifecycle with pelagic larvae developing offshore. Megalopae return to the mangrove forest to settle, i.e., metamorphose into benthic juveniles but its environmental drivers remain poorly understood. We postulate that conspecific crabs facilitate recruitment. In the field, we investigated whether the number of recruits is higher near conspecific burrows than in areas without conspecific bioturbation. Recruit sampling was conducted monthly from April 2008 to May 2009 along an environmental gradient. First, U. cordatus recruits of that year emerged from March to July. Intraspecific facilitation was indicated by significantly higher recruit numbers in bioturbated than in non-bioturbated substrates. Recruits were most abundant in zones with intermediate conditions of inundation, leaf litter standing stock, sediment consistency, luminosity, temperature, salinity, and pH. Avoidance of more inundated zones likely reduces predation by fishes and of less inundated zones helps individuals escape more stressful, drier environmental conditions. The observed habitat-specific recruitment pattern must be considered when designing field assessments of the population structure of U. cordatus (which should include sampling recruits) and enhancing stocks by releasing laboratory-cultivated larvae and first juveniles into the wild. mangroves offshore settle ie i e i.e. understood bioturbation 200 gradient First U July nonbioturbated non substrates inundation stock consistency luminosity temperature salinity pH stressful habitatspecific habitat specific which laboratorycultivated laboratory cultivated wild i.e 20 2

Resumen: En | Texto: En | PDF: En

Abstract Mangroves buffer metals transfer to coastal areas though strong accumulation in sediments making necessary to investigate metals’ bioavailability to plants at the rhizosphere. This work evaluates the effect of mangrove root activity, through iron plaque formation, on the mobility of iron and copper its influence on metals’ uptake, and translocation through simultaneous histochemical analysis. The Fe2+ and Fe3+ contents in porewaters ranged from 0.02 to 0.11 µM and 1.0 to 18.3 µg.l-1, respectively, whereas Cu concentrations were below the method’s detection limit (<0.1 µM). In sediments, metal concentrations ranged from 12,800 to 39,500 µg.g-1 for total Fe and from 10 to 24 µg.g-1 for Cu. In iron plaques, Cu concentrations ranged from 1.0 to 160 µg.g-1, and from 19.4 to 316 µg.g-1 in roots. Fe concentrations were between 605 to 36,000 µg.g-1 in the iron plaques and from 2,100 to 62,400 µg.g-1 in roots. Histochemical characterization showed Fe3+ predominance at the tip of roots and Fe2+ in more internal tissues.

Resumen: En | Texto: En | PDF: En

ABSTRACT Namalycastis abiuma has been recorded as a worldwide distributed species, found in most tropical and subtropical mangroves and estuarine environments. However, this status has been questioned in several publications, which indicate that several distinct species are being identified under the name N. abiuma. In this study, we perform a morphological analysis, along with a series of species delimitation tests and a phylogenetic analysis-using the molecular marker 16S-to evaluate whether analyzed populations previously identified as Namalycastis abiuma belong to the same species. We used sequences from the GenBank database in the analysis, as well as six newly sequenced specimens collected from the coast of Brazil, two of them from the N. abiuma type-locality. For species delimitation, we applied the Generalized Mixed Yule Coalescent (GMYC), the Assemble Species by Automatic Partitioning (ASAP), and the Multi-rate Poisson Tree Processes (mPTP) tests. Results from GMYC and ASAP suggest that Namalycastis abiuma may be endemic to the type-locality and that all other populations studied represent a second distinct species. However, mPTP indicates that all Namalycastis species included should be grouped into one single species. The mPTP results seem to be biased due to data limitation as it showed poor statistical support. Our morphological data, especially on the shape and dentition of the sub-neuroacicular falciger blades, support the GMYC and ASAP results, suggesting restricted endemism for Namalycastis abiuma. Based on these results, we conclude that N. abiuma is restricted to its type-locality and we provide a description of a new species, Namalycastis lanai sp. nov. occurring in Brazilian waters from 22°S to 27°S, including, at its southern range, an overlap with N. abiuma at Florianópolis. Finally, we provide a key to all Namalycastis species found in Brazil. environments However publications N study analysis analysisusing using 16Sto Sto 16S S Brazil typelocality. typelocality type locality. locality GMYC, , (GMYC) ASAP, (ASAP) Multirate Multi rate (mPTP subneuroacicular sub neuroacicular blades sp nov 22S 22 27S 27 27°S including range Florianópolis Finally (GMYC (ASAP 2

Resumen: En | Texto: En | PDF: En

Mangroves are highly productive ecosystems that support a diverse range of plant, animal, and microorganism species, especially fungi. This ecosystem is characterized as a transition zone between sea and land which is interesting because this environment can be considered an extreme environment due to the peculiar characteristics that it can exhibit, which is interesting for the establishment of diverse fungal species with great biotechnological potential, these habitats are relevant for the bioprospecting of interesting secondary-metabolite-producing fungi. Fungi play an essential role in maintaining this environment and also represent a rich source of structurally diverse antimicrobial compounds. This review summarizes antibacterial, antifungal, and antiviral chemicals produced by soil/sediment-derived mangrove fungi from 1990 to 2022. plant animal exhibit potential secondarymetaboliteproducing secondary metabolite producing compounds antibacterial antifungal soil/sedimentderived soilsedimentderived soil/sediment derived soil sediment 199 2022 sedimentderived soilsediment 19 202 1 20 2

Resumen: En | Texto: En | PDF: En

Abstract Biomarkers of environmental contamination have been frequently used in the assessment of marine ecosystem quality because they provide quantitative measures of biological changes in organisms exposed to pollutants such as hydrocarbons from oil spills. Polychaetes have been tested as sentinel organisms of marine environmental health because they are abundant taxa of benthic assemblages and their sedentary lifestyle ensures chronic exposure to toxins in impacted areas. In this study, we evaluated whether the polychaete Scolelepis goodbodyi can be used as a reliable sentinel species for exposure to polycyclic aromatic hydrocarbons (PAHs) from an experimental diesel spill in a dissipative sand beach in the Southern Atlantic. The design used in this study comprised replicated control and diesel impact sites sampled four times (one, two, four and seven days) before and after the impact. Total PAH levels reached 114.0 ng g -1 in the impact site one day after the diesel spill; however, the pattern of biomarker responses in S. goodbodyi was primarily influenced by spatial variation rather than being attributed to the simulated diesel spill. The apparent absence of a contaminating effect may be linked to the low levels of the toxins retained in the sediment after the spill was simulated to elicit a response or to the presence of an efficient repair system within the organism. Furthermore, the sediments tested in this study, composed of sandy fractions, had a low capacity to concentrate PAHs after the simulated diesel spill, which may have contributed to the low significant changes in their biomarker activities. Based on our results, further studies testing other Polychaeta species and simulating oil spills in sedimentary environments composed of fine sediments such as salt marshes and mangroves may help produce evidence on more effective biomarker responses in these organisms. areas (PAHs Atlantic one, (one two days 1140 114 0 114. 1 - however S organism Furthermore fractions activities results 11

Abstract Coastal wetlands are formed by ecosystems with the potential to resist and even expand because of climate change. However, they depend on the preservation of their environmental quality and the ecosystem services they provide, including sediment accumulation, which is essential for maintaining current areas, and the presence of contiguous land areas free from human occupation, allowing for migration to higher areas in response to sea-level rise. To develop a methodology for the joint assessment of the impacts of climate change and land occupation of coastal ecosystems, this study focuses on the mangroves of Baía da Babitonga, located on the northern coast of Santa Catarina. By using projections of sea-level rise and human occupation expansion around the bay based on land cover and land use data, it was possible to identify immediate effects of sea-level rise and human occupation in the short, medium, and long term, as well as the potential expansion area for mangroves. The results indicate the need for the expansion of conservation areas, considering displacement zones towards the mainland, and the control of various stress factors that can interfere with the ecosystem's health and its ability to maintain current areas. However provide accumulation sealevel sea level Babitonga Catarina data short medium term mainland s

Resumo As zonas úmidas costeiras são formadas por ecossistemas com potencial para resistir e até se expandirem em decorrência das mudanças climáticas. Para tanto, dependem da preservação da sua qualidade ambiental e dos serviços ecossistêmicos que prestam, entre eles a acumulação de sedimentos, fundamental para a manutenção das áreas atuais, e a presença de áreas terrestres contíguas livres da ocupação humana, permitindo o deslocamento para áreas mais elevadas, acompanhando o nível do mar. De forma a desenvolver uma metodologia para a avaliação conjunta dos impactos das mudanças climáticas e da ocupação do solo sobre ecossistemas costeiros, este trabalho está focado nos mangues da Baía da Babitonga, localizada no litoral norte de Santa Catarina. Utilizando-se projeções de elevação do nível do mar e da expansão da ocupação humana no entorno da baía a partir de dados de cobertura e uso do solo, foi possível identificar efeitos instantâneos do aumento do nível do mar e da ocupação humana a curto, médio e longo prazo, além da área potencial de expansão dos manguezais. Os resultados obtidos indicam a necessidade da expansão de áreas de conservação, considerando-se também zonas de deslocamento em direção ao continente, e no controle dos diversos fatores de estresse que podem interferir na saúde do ecossistema e em sua capacidade de manter as áreas atuais. tanto prestam sedimentos atuais elevadas costeiros Babitonga Catarina Utilizandose Utilizando curto prazo manguezais conservação considerandose considerando continente

Abstract Félix Guattari traveled to Brazil several times. In 1985, he left the mainstream Brazilian academic circuit and went to Belém do Pará, in the North of the country. The aim of this article is to discuss the arrival of Félix Guattari to Belém do Pará, in 1985. As a method, we use Oral and Cultural History to describe and analyze the resonances of this arrival. We analyzed oral sources and newspaper records that could present passages of the Guattari event, in Belém. We found that the invitation to Guattari was made by professors related to Psychoanalysis who had political and critical readings. Félix gave two lectures: “Social Movements and Political Parties” and “Desire and Politics”, in an auditorium of a hotel in the city. After this passage, countless inflections were produced and resonances generated in training in Psychoanalysis, in Psychology, in the Arts, in Culture and in political resistance, in “City of Mangroves”. times 1985 Pará country method event readings lectures Social Parties Desire Politics, Politics , Politics” city passage Psychology Arts resistance City Mangroves.

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.
