Ecological niche modeling of Stenella dolphins (Cetartiodactyla: Delphinidae) in the southwestern Atlantic Ocean

摘要: Abstract Since the Moreno's et al. (2005) work, no study was done to update distribution patterns of Stenella dolphins in southwestern Atlantic Ocean. Ecological niche modeling used redefine this area Maximum entropy method (Maxent) employed generate models using a set environmental variables as explanatory location records obtained by sighting and accidental captures. All ecological performed returned AUC values > 0.9. Areas with high suitability for pantropical spotted dolphin ( attenuata ), Clymene clymene ) spinner longirostris are found warm (> 25 °C) deep waters (≥ 1000 m). High frontalis seems occur between 20.5°S 30°S southeastern Brazilian coastal waters. The projected maps species distributions showed closely related changes at fine spatial scale added valuable information about offshore limits those oceanic species. results suggest that different have distinct requirements
