Fecal glucocorticoid metabolites can be used as a stress indicator in bottlenose dolphins (Tursiops truncatus)

Open Veterinary Journal
Background: Glucocorticoids increase in response to the hypothalamic–pituitary–adrenal axis stimulation, and their metabolites can be measured in dolphins' feces.

Is Blood Thicker Than Water? The Influence of Kin Within a Bull Shark Social Network

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how kinship (“kinfluence”) shapes social structure in an aggregation of adult bull sharks in Fiji by integrating genomic relatedness, pedigree reconstruction, and detailed behavioral data. It reveals that while genetic relatedness has a small but significant influence on social behavior, especially among males, kin‐category ...

Mitochondrial Variation of Bottlenose Dolphins (Tursiops truncatus) from the Canary Islands Suggests a Key Population for Conservation with High Connectivity within the North-East Atlantic Ocean

Animals
In recent decades, worldwide cetacean species have been protected, but they are still threatened. The bottlenose dolphin (Tursiops truncatus) is a vulnerable keystone species and a useful bioindicator of the health and balance of marine ecosystems in ...

A Comparison between Passive airDNA Collection and Extraction Methods on the Recovered Terrestrial Vertebrate Assemblage

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Filtering airDNA, as with other biomonitoring tools, requires rigorous methodological testing before widespread implementation. Here, we assess the comparative performance of three collection matrices: medical gauze, paraffin gauze and PCR plate seals, alongside four readily available extraction kits: Qiagen DNeasy Blood & Tissue, Qiagen PowerSoil Pro,

Life History and Reproductive Parameters in an Increasingly Abundant Killer Whale Population

Ecology and Evolution, Volume 16, Issue 8, August 2026.
In the coastal waters of the eastern North Pacific, multiple discrete populations of killer whales exhibit distinct patterns in demography and abundance that are partially captured by population vital rates. We used 50 years of photographic identification data to estimate parameters relevant to maturation, fecundity, and mortality for a unique ...

Social information about others' affective states in a human‐altered world

Journal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Mercury and Selenium Accumulation in the Tissues of Stranded Bottlenose Dolphins (Tursiops truncatus) in Northeast Florida, 2013–2021

Animals
Bottlenose dolphins (Tursiops truncatus) are long-lived marine mammals, upper-level predators, and they inhabit near-shore environments, which increases their exposure to pollution.
