Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We examined clinal gradients in reproductive modes and associated offspring body condition across a hybrid zone between two bimodal viviparous subspecies of Salamandra salamandra. We found a clear cline in reproductive modes, with pure modes at the extremes and mixed modes in central populations.

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 ...
