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

This study shows that Eastern Hellbender embryos exposed to hypoxia have lower viability, reduced hatching success, and smaller hatchlings #Herpetology #ConservationBiology

Oxygen Consumption of the River Nerite Theodoxus fluviatilis in Different Salinities The river nerite Theodoxus fluviatilis (Linneaus, 1758) is an euryhaline osmoconformer found in freshwater (FW) and brackish water (BW) habitats across Europe and western Asia. In northern Germany, T....

The river nerite Theodoxus fluviatilis shows distinct freshwater (FW) and brackish water (BW) ecotypes. BW snails keep respiration stable across salinities, while FW snails’ oxygen consumption drops as salinity rises #StressPhysiology

Lizards and the colors we can’t see! 🦎✨ Juvenile Podarcis muralis undergo ontogenetic color changes that are invisible to humans but perceptible to conspecifics, likely functioning as social signals. #Herpetology

PP1γ2 is key to sperm maturation and motility in tree shrews. This study shows PKA activates SRC, which then inhibits PP1γ2-mediated Ser/Thr phosphatase activity, boosting caudal sperm motility #CellSignaling

Like mother, like hatchling? 🐢 This sea turtle study shows hatchling innate immunity (hemolytic capacity) is linked to maternal traits, higher with maternal hemolysis and body mass, lower with maternal body length, and unchanged by immune challenge #SeaTurtles
