Small dietary changes yield growth benefits in lesser black‐backed gull chicks

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Global environmental changes alter the availability and predictability of marine resources, forcing marine predators to adapt their diets and foraging strategies. Lesser black‐backed gulls Larus fuscus exhibit individual differences in foraging consistency within and across years, which could influence reproductive success.

Depleted Dissolved Oxygen Concentrations Impair the Embryonic and Early Larval Development of Eastern Hellbenders (Cryptobranchus alleganiensis)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 2, Page 112-126, March 2026.
ABSTRACT Depletion of dissolved oxygen (DO; hypoxia) and its influence on sensitive fauna and vulnerable life stages is an emerging concern in lotic freshwater ecosystems. A species particularly vulnerable to hypoxia is the Eastern Hellbender—a large‐bodied, fully aquatic salamander which relies on cutaneous respiration and has evolved to thrive in ...

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela)

open access: yesJournal of Morphology, Volume 287, Issue 3, March 2026.
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...
