• Abstract

  Anomurans Aegla spp. are endemics of South American Neotropical fauna and are fragile in environmental disturbance so much that there are species in extinction dangerous. Aegla castro has a geographical distribution of southern region of São Paulo state until northern Parana state, a wide distribution that could represent a complex of cryptic species. The aim of this project is to study i…

• Abstract

  Investigations about mechanisms that allows stable coexistence of similar species are essential to preserve the local fauna. The hermit crabs are known as good models for resource partitioning studies due the inmost relationship with empty gastropod shells. Seeing that Ubatuba bay host a considerable hermit crab richness, the main goal is test what biological and environmental processes m…

• Abstract

  Aeglids are endemic to the Neotropical region of South America, important in nutrient dynamics and energy flow, considered a bioindicador of water quality. Our objectives are describe the interactions of trophic web through nitrogen (N) and carbon (C) levels: 1) Checking whether occurs distinction during the ontogenetic development (adult and juvenile), and 2) whether the environment more…

• Abstract

  Trawling is one of the most important commercial activities that exist in the Ubatuba region, and it has target species like pink shrimp (Farfantepenaeus brasiliensis and F. paulensis) and sea-bob shrimp (X. kroyeri). This type of fishing is random, and besides the target species, it is collected a bycatch fauna which they have lower or null economic value. In this way, with the crescent …

• Abstract

  The FAPESP PhD proposal has the focus on the ecological interactions of marine fauna to understand the trophic chain with the use of stable isotopes tools as Isotopic Mixing Models. In this study, we intend to analyse the marine fauna inhabiting the area of the Iguape-Cananéia-Paranaguá Lagoon-Estuarine Complex, a "Biosphere Reserve of the Atlantic Forest and Natural Patrimony of Humanity…
