Dados dos parâmetros ambientais (temperatura do ar, temperatura da água e salinidade) foram também obtidos. cada período foram coletados mensalmente 10 indivíduos. Foram realizadas oito coletas na região entre marés, em baixa-mar de sizígia, durante dois períodos: julho a outubro de 2010 e janeiro a abril de 2011, em três níveis (Superior, Médio e Inferior), com três réplicas. subrugosa em um costão rochoso da Ilha do Mel, Paraná, Brasil (25° 33’ 47,6” S 48° 19’ 05,8” W). View projectĮste trabalho tem como objetivo analisar o período reprodutivo do gastrópode L. We extracted a cast of such a system in 'Interrelationships among ecological factors of brachyuran crabs, trees and soil in mangrove community assemblage in Northeast Brazil', Community Ecology, 20(3): 277-290, 2019. The existence of systems of anastomosed burrows inhabited by several Brachyuran species among the roots of Rhizophora, allows the increase of diversity of this significant functional group of Crustaceans in red mangrove forests. mangle (through root architecture) and key Grapsoid crab Goniopsis cruentata (through differential propagule consumption) are significant in shaping the mangrove community assemblage (for example, their architecture, carbon stock, etc.). We found that the ecosystem engineering capacity of R. The goal is to better understand how the niche of trees and Brachyuran crabs interacts in shaping mangrove architecture and other community's emergent properties. On the other hand, and to gain more insights on the assemblage of mangrove community, we study the interactions among trees, crabs and soil in mangroves. In a coming article, we will comment and discuss the results and the several insights on the ecological factors and processes that influence the mangrove community reestablishing at salt-flats/saltworks. After the construction of several channels that brings water from the river to inside the saltwork, planted and natural propagules of Rhizophora mangle, Laguncularia racemosa and Avicennia developed more in 4 years that in decades after saltwork deactivation. Other restoration site/project is in course in the Pacoti River, State of Ceará, also in northeast Brazil, in an abandoned salt production area, self-recoverd partially only with Avicennia germinans mangroves. Interesting findings emerge from this project, detailed in the 'Mangrove Carbon stock assessment, Status and Conservation' Project herein. This year, the 3rd quinquennial monitoring will start after the rain season. In the Jaguaribe River (Natal, Rio Grande do Norte State, Northeast Brazil) monitoring and assessment of mangrove development in the restored areas continue. Two integrated projects of research are currently in execution. Finally, this chapter reviews the major anthropogenic threats (urbanization, aquaculture, invasive species, mining, climate change, and petroleum and gas exploration) and makes recommendations for further research and conservation programs. Major knowledge gaps remain the baseline research on benthic communities in mesophotic and deep-sea reef ecosystems in this marine region.

Furthermore, it presents synthetic information regarding the ecology and diversity of the benthic suspension feeders (sponges, scleractinian corals, octocorals, zoanthids, mollusks, ascidians, and bryozoans) in southwestern Atlantic. This chapter presents a review of the environmental characteristics and benthic habitats along the coast of Brazil (coral reefs, intertidal sandstone reefs, benthic communities in rocky shores, continental shelf communities, oceanic islands, etc.). The Brazilian marine animal forests (BRAF) in the “Blue Amazon” can be compared to their rainforest counterpart: an ecosystem with high diversity, but relatively unknown. Interestingly, these benthic communities generate three-dimensional structures along the Brazilian coast, similar to the trees in the Amazon rainforest. This area is possibly one of the most important benthic biodiversity hotspots in the world however, there is a lack of scientific knowledge about its marine biodiversity. The Brazilian authorities refer to this marine area as the “Blue Amazon,” being rich in biodiversity and ecosystem services, and similar in extension to the country’s rainforest. The southwestern Atlantic Ocean is the final Brazilian maritime frontier.
