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 ...

Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

The Anatomical Record, Volume 309, Issue 2, Page 397-416, February 2026.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Age‐Specific Survival Estimation of a Eurasian Crane Population Highlights a Long‐Term Decline in Juvenile Survival

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The Eurasian crane (Grus grus), a symbol of conservation success in Europe, has made an impressive recovery. However, our results show that over the study period, juvenile survival declined by almost 30% overall, while sub‐adults experienced a smaller decrease, and adults showed no change.

Integrating Multiple‐Covariate Distance Sampling and Habitat Modeling to Inform Conservation of the Asian Houbara in Central Iran

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We combined multiple‐covariate distance sampling (MCDS) with habitat modeling to estimate the abundance and habitat associations of the vulnerable Asian houbara (Chlamydotis macqueenii) in central Iran. Line‐transect surveys in spring 2022 yielded an estimated density of 0.53 individuals/km2 (~5293 birds), with nearly identical results from ...
