Estimates of Blue Whale Growth and Reproductive Parameters From Historical Whaling Data

Marine Mammal Science, Volume 43, Issue 1, January 2027.
ABSTRACT During 20th‐century whaling, blue whales (Balaenoptera musculus) were hunted to near extinction. Biological data, such as earplugs and ovarian corpora, were collected during whaling and provide information about key demographic parameters that can inform population status.

Quantifying the Association Between Inbreeding and Mortality in Endangered St. Lawrence Estuary Beluga Whales

Marine Mammal Science, Volume 43, Issue 1, January 2027.
ABSTRACT Understanding factors that limit the growth of endangered populations is crucial for conservation. Depleted populations are vulnerable to losses of genetic variation and inbreeding depression. Genetic factors have been cited as one of the potential contributors to the lack of recovery of the isolated St.

Stable Isotope Analysis (δ13C, δ15N and δ18O) of Killer Whale Dentine: Evaluating Treatment Methods and Establishing Best Practices

Rapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.
ABSTRACT Rationale Stable isotope measurements in odontocete teeth can be used to reconstruct lifetime ecology, but some pre‐treatments may introduce bias. Isolating dentine collagen with HCl decalcification, removing the organic matrix or drying dentine prior to the analysis of structural carbonates can introduce unintended variability, limiting ...

The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

The Anatomical Record, Volume 309, Issue 12, Page 3571-3587, December 2026.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, Volume 101, Issue 6, Page 2597-2612, December 2026.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...
