Dear colleagues, I am pleased to share our newly published article in Frontiers in Marine Science (published today, 9 January 2026):
Lopez-Marulanda, J., Maceido de Queiroz, R. E., & De Lima Silva, F. J. (2026). Social and Environmental Drivers of Foraging Behavior in Guiana Dolphins (Sotalia guianensis) in Northeastern Brazil. Frontiers in Marine Science. https://doi.org/10.3389/fmars.2025.1695002 Abstract Understanding how environmental and anthropogenic factors shape foraging behavior is essential for the conservation of coastal cetaceans. We investigated social and environmental drivers of foraging behavior in Guiana dolphins (Sotalia guianensis) at Praia do Madeiro, northeastern Brazil, using land-based observations conducted between March and June 2008. We applied generalized linear models to examine the effects of temporal variables (month and hour), tidal stage, spatial zone, boat condition, and prey escape behavior on (i) foraging event frequency and (ii) the probability of collective foraging. Foraging frequency was significantly influenced by boat presence and engine status, as well as by seasonal and diurnal patterns. Collective foraging probability varied according to spatial zone and prey escape behavior, with higher coordination observed when prey exhibited escape responses. Our results highlight the combined influence of anthropogenic disturbance and ecological ! context on foraging dynamics in S. guianensis, emphasizing the importance of managing human activities in critical coastal habitats.
