Ontogeny of the Heat‐Induced Hatching Response in the Red‐Eyed Treefrog, Agalychnis callidryas In ectothermic vertebrates, temperature impacts the rate and success of embryonic development, and in some species, embryos show adaptive behavioral responses to thermal conditions. The arboreal embr...

Escaping from heat starts early 🐸🌡️ Red-eyed treefrog (Agalychnis callidryas) embryos hatch in response to heat earlier than previously reported, and at a stable thermal limit #ThermalBiology #ClimateChange

Wild‐Derived House Mice (Mus musculus) Are Able to Cope With a Constant Light Environment Exposure to altered nighttime lighting conditions has become common in today's modern world. Light at night disrupts circadian processes that govern feeding patterns, sleep/wake cycles, and metabolic...

Keeping up with light pollution! 🌗 🐭 After 6 weeks of constant light or darkness, wild-derived house mice (Mus musculus) showed no major changes in mitochondrial function, oxidative damage, or body condition. #Chronobiology

Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heterocl...

Exposure of mummichog (Fundulus heteroclitus) to 17α-Ethinylestradiol during early development influences sex determination and feminizes fish. #EndocrineDisruption

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

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
