Living Near the Surface: Dive Behavior of Sei Whales (Balaenoptera borealis) in the Southwestern Atlantic Ocean

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding the diving behavior of baleen whales in tropical breeding areas is essential for evaluating both ecological functions and anthropogenic threats. In this study, we combined satellite transmitters and generalized additive mixed models (GAMMs) to investigate the dive behavior of sei whales (Balaenoptera borealis) in Santos Basin (SB)

Molecular Responses to Climate Change: How Warming and Acidification Reshape the Proteome and Phosphoproteome of the Endangered Mira Chub

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Global environmental change affects organisms, including their physiology. In freshwater ecosystems, where migration is limited, populations often rely on phenotypic plasticity to respond. While transcriptomics has been widely used to study stress responses at the molecular level, less is known about the proteome, which reflects post ...

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...
