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.

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. 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 Introduction: The mangrove is one of the most important ecosystems on the planet, due to the ecological role it plays on coastlines, it provides development, protection, and feeding areas for various species. Objective: To determine the diversity and annual fluctuation of the cerambycid community, as well as the vertical distribution of species richness associated with the edge and interior of a mangrove in Tabasco, Mexico. Methods: The sampling was carried out from August 2016 to July 2017. The capture of insects was performed with interception traps baited with ethanol 70 % at 1.5, 6, and 12 m height, on the edge and interior of the mangrove. Results: A total of 382 specimens were collected, belonging to three subfamilies, 25 genera, and 36 species; Laminae was the subfamily most diverse with 24 species, followed by Cerambycinae with 11 species. At the edge of the mangrove 31 species were captured, and 21 in the interior. The 1D index determined that the edge was 2.51 more diverse than the interior, with a similarity of 61 %, sharing 16 species. The fluctuation of the communities on the edge and interior presented remarkable differences during the sampling year. On the edge, the greatest species richness was recorded at 6 m height and in the interior at 1.5 m and 6 m. Conclusions: Studies related to the vertical distribution of this group of insects, together with the increase in collection time and using complementary techniques, could give better results to inventory a larger number of species in the ecosystems.

Conclusión: Los estudios relacionados con la distribución vertical de este grupo de insectos, aunado al incremento del tiempo de recolecta y utilizando técnicas complementarias, podrían dar mejores resultados para inventariar el mayor número de especies en los ecosistemas.

Abstract The Puerto Pizarro mangrove is part of the Tumbes mangrove, the largest in Peru; it is also the mangrove with the greatest anthropic impact in the region; in this area, no studies have been carried out on the status of its population of Rhizophora mangle, the most important mangrove species in the Peruvian mangroves. The objective of this research was to establish the structural characteristics of R. mangle in the Puerto Pizarro mangrove. The study was carried out by subdividing the research area into three zones (A, B and C), in which 41 plots of 1 ha each were selected, in each plot a sub-area of 0.25 ha (50 m x 50 m) was taken). In these sub-areas, mangrove trees of the species Rhizophora mangle, Laguncularia racemosa and Avicennia germinans were evaluated regarding their structural characteristics: diameter at breast height (DBH), height, basal area, density, frequency, dominance and index value of ecological importance (IVI). It was found that R. mangle had a greater DAP, height and basal area than the other species; also, higher density, frequency, dominance and relative IVI (adjusted to 100%) than the other species with values of 51.5%, 100%, 82.6% and 53.3%, respectively. The research findings allow us to conclude that the population of R. mangle in the Puerto Pizarro mangrove is a mature population, with a predominance of stems and latizales. However, its structural characteristics are not homogeneous throughout the Puerto Pizarro area, since zone A, with less anthropic impact and lower salinity, has R. mangle trees with better structural characteristics than those in zones B and C in which there is greater anthropic activity and greater salinity.

Resumen El manglar de Puerto Pizarro forma parte del manglar de Tumbes, el más grande del Perú; es también el manglar con mayor impacto antrópico en la región; en este no se han realizado estudios sobre el estado de su población de Rhizophora mangle, la especie de mangle más importante de los manglares peruanos. Esta investigación buscaba establecer las características estructurales de R. mangle en el manglar de Puerto Pizarro. El estudio se realizó subdividiendo el área de investigación en tres zonas (A, B y C), en las cuales se seleccionaron 41 parcelas de 1 ha cada una, en cada parcela se tomó una sub-área de 0,25 ha (50 m x 50 m). En estas sub-áreas se evaluaron los árboles de mangle de las especies Rhizophora mangle, Laguncularia racemosa y Avicennia germinans respecto a sus características estructurales diámetro a la altura del pecho (DAP), altura, área basal, densidad, frecuencia, dominancia e índice de valor de importancia ecológica (IVI). Se encontró que R. mangle presentó un mayor DAP, altura y área basal que las otras especies; así también, mayor densidad, frecuencia, dominancia e IVI relativos (ajustados al 100%) que las otras especies con valores de 51,5%, 100%, 82,6% y 53,3%, respectivamente. Los hallazgos de la investigación permiten concluir que la población de R. mangle del manglar de Puerto Pizarro es una población madura, con predominancia de fustales y latizales. En Puerto Pizarro, sus características estructurales no son homogéneas, ya que la zona A, con menor impacto antrópico y menor salinidad, presenta árboles de R. mangle con mejores características estructurales que los de las zonas B y C, donde hay mayor actividad antrópica y mayor salinidad.

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 Tropical wetland forests are fragile ecosystems facing critical risks due to global warming and other anthropogenic threats. Hence, gathering accurate and reliable information on them is urgent. Although remote sensing has demonstrated great potential in studying terrestrial ecosystems, remote sensing-based wetland forest research is still in an early stage of development. Mapping wetland forests, particularly mangrove forests, was an initial goal of this approach and is a task that still faces methodological challenges. Initially based on aerial photography only, wetland forest mapping through remote sensing underwent explosive diversification after the launching of artificial satellites in the 1970s. Later, precision in wetland forest mapping increased with the combination of hyperspectral, multispectral, and high and very high-resolution imagery. Accurate delimitation of wetland forest extent is also necessary to assess their temporal dynamics (losses, gains, and horizontal displacement). Despite the prevalence of mapping studies, current remote sensing-based research on wetland forests addresses new questions and novel aims, such as describing and predicting wetland forest attributes through mathematical modeling. Although this approach has made substantial progress in recent decades, modeling and predicting wetland forest attributes remain insufficiently explored fields of research. Combining active and passive sensors is a promising alternative to provide a more accurate picture of these communities’ attributes. In particular, LiDAR and radar-based technologies may help overcome difficulties encountered in older studies. In the future, we will witness conceptual and methodological progress that will enable us to surmount the remaining challenges.

Resumen Los humedales arbóreos tropicales están críticamente amenazados por el calentamiento global y otras amenazas antropogénicas; por ello, urge recopilar información confiable sobre estas comunidades vegetales. Aunque la percepción remota ha demostrado gran potencial en el estudio de ecosistemas terrestres, la investigación de los humedales arbóreos con este enfoque requiere mayor desarrollo. El mapeo de los humedales arbóreos (particularmente manglares), que fue el objetivo inicial de este enfoque, aún enfrenta desafíos metodológicos. Inicialmente basado solo en fotografías aéreas, el mapeo de humedales arbóreos se diversificó explosivamente con el lanzamiento de satélites artificiales y la interpretación de imágenes de percepción remota. La precisión de los mapas de estas comunidades aumentó con el uso combinado de imágenes multiespectrales, hiperespectrales, de alta y muy alta resolución. Para evaluar la dinámica temporal (pérdidas, ganancias, desplazamiento horizontal) de los humedales arbóreos necesitamos delimitar de manera precisa su extensión. Aunque todavía se están cartografiando numerosos humedales arbóreos, la investigación actual de estos ecosistemas por percepción remota aborda nuevas preguntas y objetivos (e.g., predecir los atributos comunitarios por medio de modelos matemáticos). A pesar de sustanciales avances recientes, el modelado y la predicción de los atributos de los humedales arbóreos siguen siendo temas poco explorados. La combinación de sensores activos y pasivos es una alternativa promisoria para evaluar con precisión los atributos de estas comunidades, y las tecnologías de radar y LiDAR pueden ayudar a superar dificultades enfrentadas en el pasado. Los avances conceptuales y metodológicos en el futuro permitirán superar los desafíos que aún persisten.

ABSTRACT: The aim of this research was to determine the alpha and beta diversity of mangrove trees in the Tumbes mangrove forest. The mangrove forest area was divided into three zones: A, B and C, in which 41 sampling points (PM) were taken. Mangrove trees were counted and measured, and the alpha diversity indices were determined: Shannon-Wiener (H'), Simpson (DS) and Pielou (J’), as well as the similarity of the PM. Beta diversity is determined with the indices: Jackard (IJ) and quantitative Sorensen (S). It is considered that the alpha diversity of the mangrove forest was low (H'=1.0260, SD =0.6158 and J’=0.9339), with zone A being the one with the lowest diversity (H'=0.3048, SD=0.8531 and J’=0.2774), due to its less anthropic impact and due to the dominance of Rhizophora mangle over the other species, it was observed that the PM were very similar within each zone, with lower diversity in zone A. The beta diversity evaluated using IJ was 1, indicating that the diversity of species does not change between the zones, while the S index showed that there is a greater change in diversity between zone A and the remaining zones. These results can allow local and regional authorities to make decisions to protect said mangrove forest. On the other hand, it would also be advisable to carry out research to determine the impact that alterations in mangrove species biodiversity may have on the organisms that inhabit this mangrove forest.

RESUMEN: El objetivo de la investigación fue determinar la diversidad alfa y beta de los árboles de mangle en el manglar de Tumbes. El área del manglar se dividió en tres zonas: A, B y C, en ellas se tomaron 41 puntos de muestreo (PM). Se contaron y midieron los árboles de mangle y se determinaron los índices de diversidad alfa: Shannon-Wiener (H’), Simpson (DS) y Pielou (J’), así como la similitud de los PM. La diversidad beta se determinó con los índices: de Jackard (IJ) y cuantitativo de Sorensen (S). Se determinó que la diversidad alfa del manglar fue baja (H’=1,0260, DS=0,6158 y J’=0,9339), siendo la zona A la de menor diversidad (H’=0,3048, DS=0,8531 y J’=0,2774), por su menor impacto antrópico y por el dominio de Rhizophora mangle sobre las otras especies, se observó que los PM fueron muy similares dentro de cada zona, con menor diversidad en la zona A. La diversidad beta evaluada mediante IJ fue de 1, indicando que la diversidad de especies no cambia entre las zonas, en tanto que el índice S mostró que hay un mayor cambio en diversidad entre la zona A y las restantes zonas. Estos resultados pueden permitir a las autoridades locales y regionales tomar decisiones a fin de poder proteger a dicho manglar. Por otro lado, también sería conveniente realizar investigación para determinar el impacto que la alteración de la biodiversidad de las especies de mangles pueda tener en los organismos que habitan en este manglar.

Ecosystem Services Based Mangrove Forest with Management Strategies, which were filtered into 10 journals according to the theme and analyzed by reviewing them. Ecosystem Services Based Mangrove Forest with Management Strategies. The research results show that mangrove ecosystem services with an area of 88,556 ha was Rp 6,961,126,186,194 year-1 (US$ 467,974,555.06 year-1) or Rp 78,607,444 ha-1-1 (US$ 5,284.5 ha-1year-1). Ecosystem Services Based Mangrove Forest with Management Strategies, that there are three main components that must be considered in efforts to manage and utilize mangrove ecosystems and coastal natural resources, namely; 1) social activity(social processes) provide socialization or understanding to the community about the importance of protecting mangrove forests and the benefits that the community will receive 2) the economy(economic processes) take advantage of the existing potential by planting mangrove trees, and 3) the natural resources themselves(natural processes) Mangrove forest management includes establishing protected forest areas for mangrove forest conservation so that they are well maintained and sustainable. From the socio-economic, cultural and human aspects, natural resources are needed to be able to continue their lives, on the other hand, the existence or sustainability of coastal natural resources is very dependent on human activities as the main users of natural resources. examine Strategies Resources Scholar Pubmed study 20182023 2018 2023 2018-202 17000 17 000 17,00 1 them 88556 88 556 88,55 6961126186194 6 961 126 186 194 6,961,126,186,19 year1 year year- US$ US (US 46797455506 467 974 555 06 467,974,555.0 78607444 78 607 444 78,607,44 ha11 ha-1- 52845 5 284 5,284. ha1year1. ha1year1 hayear 1year . ha-1year-1) activitysocial activity processes 2 economyeconomic economy economic trees 3 themselvesnatural themselves sustainable socioeconomic, socioeconomic socio economic, socio-economic aspects lives hand 2018202 201 202 2018-20 1700 00 17,0 8855 8 55 88,5 696112618619 96 12 18 19 6,961,126,186,1 4679745550 46 97 0 467,974,555. 7860744 7 60 44 78,607,4 ha1 ha-1 5284 28 5,284 ha1year ha-1year-1 201820 20 2018-2 170 17, 885 88, 69611261861 9 6,961,126,186, 467974555 4 467,974,555 786074 78,607, ha- 528 5,28 ha-1year- 20182 2018- 6961126186 6,961,126,186 46797455 467,974,55 78607 78,607 52 5,2 ha-1year 696112618 6,961,126,18 4679745 467,974,5 7860 78,60 5, 69611261 6,961,126,1 467974 467,974, 786 78,6 6961126 6,961,126, 46797 467,974 78, 696112 6,961,126 4679 467,97 69611 6,961,12 467,9 6961 6,961,1 467, 696 6,961, 69 6,961 6,96 6,9 6,

Resumo Este estudo analisa os serviços ecossistêmicos fornecidos por florestas de manguezal e propõe estratégias de manejo para a sustentabilidade dos recursos naturais costeiros. A metodologia utilizada foi a revisão sistemática, ou seja, pesquisa bibliográfica que examina periódicos críticos e de qualidade, revisados por pares em bancos de dados como Google Scholar, Pubmed, Science Direct e Researchgate. Uma pesquisa de artigos de 2018-2023 retornou 17.000 resultados com as palavras-chave “Serviços Ecossistêmicos de Florestas de Manguezal com Estratégias de Manejo”. Após filtragem de acordo com o tema, foram analisadas 10 publicações científicas. Os resultados da pesquisa mostraram que os serviços ecossistêmicos de mangue com uma área de 88.556 ha foram de Rp 6.961.126.186.194 ano-1 (US$ 467.974.555,06 ano-1) ou Rp 78.607.444 ha-1-1 (US$ 5.284,5 ha-1ano-1). O estudo também identificou três componentes principais a serem considerados no manejo e utilização dos ecossistemas de manguezais e recursos naturais costeiros: 1) a atividade social (processos sociais) proporciona socialização ou compreensão à comunidade sobre a importância de proteger os manguezais e os benefícios que a comunidade receberá; 2) a economia (processos econômicos) aproveita o potencial existente plantando árvores de mangue; e 3) os próprios recursos naturais (processos naturais). O manejo dos manguezais inclui o estabelecimento de áreas florestais protegidas para a conservação das florestas de manguezais, para que sejam bem mantidas e sustentáveis. Do ponto de vista socioeconômico, cultural e humano, os recursos naturais são necessários para poder continuar as suas vidas.

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

Abstract The present work describes the phytophysiognomies and inventories the remaining floristic diversity of the Brisas Environmental Protection Area, which is located on the coast of Sepetiba Bay in the state of Rio de Janeiro, Brazil, covering approximately 101 hectares. Three phytophysiognomies were identified and described, namely Restinga, the Lowland Dense Ombrophylous Forest and the Mangrove. Different types of vegetation can be recognized for Restinga, such as beaches and dunes, those located on sandy ridges, in this case represented by Low and High Restinga forests, and the vegetation associated with depressions, such as the Swampy Restinga and Swampy forest. The floristic survey identified 311 species, distributed in 231 genera and 86 families. Herbaceous plants represent 29.26% of the flora, followed by vines (27.75%), trees (27.33%), shrubs (14.46%) and epiphytes (4%). Restinga is home to 81% of the flora, followed by the Lowland Dense Ombrophylous Forest (28.30%) and the Mangrove (2.25%). The most representative families were Fabaceae (38 spp.), Euphorbiaceae (15 spp.), Asteraceae (14 spp.) and Sapindaceae (14 spp.). The area has low floristic similarity with other areas of the state of Rio de Janeiro, but it has a greater grouping with restingas from the state of Rio de Janeiro.

ABSTRACT The mangrove ecosystems are characterized by being one of the most productive, despite their poor soils, finding a great faunal richness. Meanwhile, pseudoscorpions are arachnids that inhabit all terrestrial ecosystems, and diverse in the tropics and subtropics. We evaluated the relationship of pseudoscorpions composition in mangrove forest fragments in the southern Gulf of Morrosquillo, using different metrics related to vegetation and land use. A total of 1063 individuals were collected, distributed in four families and eight species. Three indicator species of good conservation status were identified, Pachyolpium isolatum (Beier, 1931) a good indicator (A = 1.0; B = 0.93; p <0.001), and four detecting species of disturbed mangroves. The proximity to urban and tourist areas influences the composition of the community of the pseudoscorpion. The indicator capacity and the sensitivity demonstrated by the species make them a valuable argument and are considered as a tool that can indicate promptly the negative effects of certain management practices in the different mangrove forest fragments in the southern Gulf of Morrosquillo. productive soils richness Meanwhile subtropics Morrosquillo use 106 collected identified Beier, Beier (Beier 1931 1.0 10 1 0 0.93 093 93 <0.001, 0001 <0.001 , 001 <0.001) mangroves pseudoscorpion 193 1. 0.9 09 9 000 <0.00 00 19 0. <0.0 <0. <0 <

RESUMEN Los ecosistemas de manglar se caracterizan por ser uno de los más productivos, a pesar de sus suelos pobres, encontrando una gran riqueza faunística. Por su parte, los pseudoescorpiones son arácnidos que habitan en todos los ecosistemas terrestres, y diversos en los trópicos y subtrópicos. Se evaluó la relación de la composición de la comunidad de pseudoescorpiones en fragmentos de bosque de manglar en el sur del Golfo de Morrosquillo, utilizando diferentes métricas relacionadas con la vegetación y el uso del suelo. Se colectaron 1063 individuos distribuidos en cuatro familias y ocho especies. Se identificaron tres especies indicadoras de buen estado de conservación, Pachyolpium isolatum (Beier, 1931) un bueno indicador (A = 1.0; B = 0.93; p <0.001) y cuatro especies detectoras de manglares perturbados. La proximidad a zonas urbanas y turísticas influye en la composición de la comunidad del pseudoescorpiones. La capacidad indicadora y la sensibilidad demostrada por las especies las convierten en un argumento valioso y son consideradas como una herramienta que puede indicar puntualmente los efectos negativos de ciertas prácticas de manejo en los diferentes fragmentos de bosque de manglar en el sur del Golfo de Morrosquillo. productivos pobres faunística parte terrestres subtrópicos Morrosquillo suelo 106 conservación Beier, Beier (Beier 1931 A 1.0 10 1 0 0.93 093 93 <0.001 0001 001 perturbados 193 1. 0.9 09 9 <0.00 000 00 19 0. <0.0 <0. <0 <

ABSTRACT We present new data and reviewed the information available on the breeding biology of the Dark-billed Cuckoo (Coccyzus melacoryphus), a widespread South American species. We collected opportunistic observations from three nests in a mangrove forest on Isabela Island, Galapagos Archipelago, Ecuador. The nests were built in forks of White Mangrove (Laguncularia racemosa) branches 5 to 9 m above the ground. They were low/cup-shaped, with intertwined branches on the outside and leaves, stipules, and strips of stem bark in the inner cup. The clutch size was three eggs, which were light green and sub-elliptical in shape. The nestling period lasted between 7 and 8 days. We observed biparental care during incubation and brooding. In addition, we documented the parasitism of the Avian Vampire Fly (Philornis downsi) on Dark-billed Cuckoo chicks.

RESUMEN Presentamos nueva información y revisamos la existente sobre la biología reproductiva del Cuclillo Canela (Coccyzus melacoryphus), una especie ampliamente extendida en Sudamérica. Recogimos información de manera oportunista de tres nidos, en manglares de la Isla Isabela, en el Archipiélago de Galápagos, Ecuador. Los nidos estaban colocados sobre horquetas de ramas de Mangle Blanco (Laguncularia racemosa), entre 5 y 9 m de altura sobre el suelo. Los nidos tenían forma de copa baja, con ramas entrelazadas en la parte externa, y hojas, estípulas y corteza de tallos en el sitio de alojamiento de los huevos y polluelos. El tamaño de puesta fue de tres huevos, los cuales fueron de color verde pálido y de forma subelíptica. Observamos cuidado biparental durante los periodos de incubación y empollamiento. El periodo de empollamiento y cría duró entre 7 y 8 días. Además, documentamos parasitismo de la Mosca Vampiro Aviar (Philornis downsi) en los polluelos del Cuclillo Canela.

ABSTRACT The biological importance of rhizosphere sediment-associated fungi in mangroves is poorly understood, especially when they are affected by high salinity and anaerobiosis in disturbed areas. This study evaluated the fungal diversity in the rhizosphere sediments of three mangrove species associated with three conservation conditions of mangrove forests in preserved, semi-preserved, and deteriorated areas. In addition, fungal bioactivity was correlated to the fungal diversity found in mangrove species from each area. We isolated 50 fungal strains belonging to three phyla, seven classes, and 10 orders. The fungal diversity was higher in the preserved area (H’ = 2.22) than in the semi-preserved (H’ = 1.73) and deteriorated areas (H’ = 1.68); the redundancy analysis showed a tendency of fungal accumulation towards the rhizosphere of Rhizophora mangle and Avicennia germinans in the preserved and semi-preserved areas. In addition, the redundancy analysis showed that 10 bioactive fungi genera tended to accumulate on the rhizosphere of R. mangle and A. germinans in the preserved and semi-preserved areas. The preserved area is related to the semi-preserved area, with a 28% Jaccard similarity coefficient. The diversity and bioactivity of the isolated fungi encourage the need to conserve and restore mangrove ecosystems considering their current and potential services, such as bioprospecting new pharmacological compounds.

ABSTRACT: In the present research, satellite images have been used, which with the appropriate processing have allowed to evaluate the existing vegetation cover in the territorial space of the protected natural area The Mangroves of Tumbes National Sanctuary - Peru and that was verified with a face-to-face tour. It was possible to determine the presence of 7 types of areas inside, 2 without water cover bodies and salty zones - sandbanks; and 5 with vegetation cover such as semi-dense dry forest, dense dry forest, low strip mangrove, middle strip mangrove and high strip mangrove. Mangrove covers occupy most of the interior of the natural area. Likewise, in the mangrove ecosystem the species with the highest value of index of importance (IVI) is the species Rhizophora mangle and in the dry forest ecosystem it is the species Caesalpinia paipai.

Abstract This study evaluated the effectiveness of Federal Protected Areas on the coast of the state of Paraíba in northeastern Brazil with regard to the preservation of mangrove forests. The study area encompassed remaining mangrove forests distributed in four federal protected areas (PAs) located in Paraíba: Area of Relevant Ecological Interest (AREI) of Mangroves of the Mamanguape River, Environmental Protection Area (EPA) of the Mamanguape River, the Restinga de Cabedelo National Forest (NATFOR), and the Acaú-Goiana Extractive Reserve (EXTRES). The methods consisted of a spatiotemporal analysis considering the year of creation of each PA, with mapping and quantification as well as the assessment of impacts and effectiveness. NATFOR and EXTRES had the most conserved mangrove areas on the temporal scale, whereas AREI and EPA had the largest reductions in areas of mangrove forest. Urban expansion, sugarcane monoculture, and shrimp farming represented the main negative impacts spatially identified in these PAs. Based on the results of this study, the mangrove forests analyzed have continually suffered anthropogenic pressures since their creation as protected areas. The greatest effectiveness in the preservation of mangrove forests was found in Acaú-Goiana EXTRES and the least effectiveness was found in the AREI of Mangroves of the Mamanguape River.
