Abstract

Biological communities present patterns of abundance, richness, diversity and composition determined by environmental filters or stochastic factors, which may cause replacement or nesting of species along environmental gradients. However, submarine canyon communities around the world are still poorly studied, leading to a lack of knowledge about their biodiversity and their patterns and processes. Given this scenario, this project aims to: (i) analyze the variations of the ecological descriptors of the community; (ii) to evaluate the spatio-temporal variation of the composition of species of the Capitellidae (Polychaeta) family; (iii) to verify whether the rates of variation in species composition is high or low by determining ²-diversity and to investigate which ecological mechanisms (Turnover and/or Nesting) and metacommunity paradigms (Patch-dynamic, Species-sorting, Mass effect and Neutral paradigm) structure these communities; and (iv) ascertain which environmental variables are responsible for structuring this metacommunity. The results are expected to elucidate questions about the organization and environmental filters that structure deep sea benthic communities in sumarine canyons, providing information that will assist in the management and delimitation of conservation areas.
