Cetacean diversity on the Parnaiba Delta, Maranhão state, northeastern Brazil

open access: yesBrazilian Journal of Biology
The increase in the research of cetacean surveys on the Brazilian coast has brought new data on the distribution of species never reported before. The present work reviews the current knowledge on cetaceans species and extends this knowledge with an ...

Hiding in Plain Sight: Evidence of Echeneidae Cloacal and Gill Diving Behavior in Manta Ray Hosts

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Here we document seven observations of Echeneidae cloacal diving behavior in manta rays and one observation of gill attachment behavior. These observations span all three currently described species of manta rays (Mobula yarae, Mobula birostris, and Mobula alfredi), demonstrate the ability of large Echeneidae to perform cloacal diving behavior in both ...

Long‐Term Demographic Trends of Near Threatened Coastal Dolphins Living in an Urban Estuary

open access: yesEcology and Evolution
Understanding population demography of threatened species and how they vary in relation to natural and anthropogenic stressors is essential for effective conservation. We used a long‐term photographic capture‐recapture dataset (1993–2020) of Indo‐Pacific

Unravelling Taxonomic Complexity in Elusive Cetaceans: Mitogenome Insights into Evolutionary History and Cryptic Diversity of Bryde's Whales

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The Bryde's whale is one of the least understood baleen whale species globally, limiting accuracy of regional and global conservation assessment. This study shows the occurrence of unique genetic lineages and evolutionary histories among Bryde's whale populations.

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

The Deep‐Sea Preyscapes of Mammalian Top Predators

open access: yesEnvironmental DNA, Volume 8, Issue 3, May‐June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.
