SUMMARY:
Describe diversity patterns it’s an important mechanism to access community ecology, and functional diversity approach has been a useful tool to understand how dimensions of biodiversity and ecology interact through the ecosystems. In coastal ecosystem of South-Western Atlantic, the high diversity of fish and diversification of environmental and geological condition, could be an interesting area to access the dimensions of biodiversity through all four completely different provinces. Thus, this study aims to investigate biogeographic patterns in the species and functional composition of the South-Western Atlantic. We collected 10113 species of four provinces from fishbase. Then, we classified them in guilds regarding their feeding habits, habitat use, energy allocation to growth and reproduction, and used their traits to obtain a functional space of the communities. Our results showed that temperate province in the south is less diverse compared to warmer provinces in the north. Taxonomic similarity was low between faraway provinces, on the other hand functional similarity and redundancy were high. The proportion of big, generalist and with maternal care species seems to be higher in the south. In contrast, the north holds small and specialist group of species. The differences in diversity and life strategies between provinces is a result of different environmental conditions through them such as river discharges, habitat complexity and productivity. Also, the niche compression in tropical habitats, help us to understand diversity of species and food items in the north provinces.
