Higher Energy Demands and Lower Body Condition in a Hot Spring: Comparing Relict Leopard Frogs at Two Thermally Contrasting Sites

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Following range‐wide decline, all remnant populations of the relict leopard frog (Rana onca) in the eastern Mojave Desert of the southwestern USA occupied geothermally influenced hot springs. In recent years, however, several large populations have been established at cold‐water sites.

Influence of Habitat Use on Prey Capture Behavior and Kinematics in the Pyrenean Brook Newt (Calotriton asper)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Caves are extreme environments that impose stringent selective pressures on organisms. Consequently, many cave dwellers show extreme adaptations such as the loss of eyes, depigmentation, and a low resting metabolic rate. Yet, how the initial stages of adaptation to these extreme environments take place remains poorly understood.

Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...

Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...

Investigating the Impact of El Niño–Southern Oscillation on Rangeland Productivity in the Limpopo Province, South Africa

International Journal of Climatology, EarlyView.
This study investigated ENSO effects on rainfall variability and rangeland productivity across Limpopo Province, South Africa, using DMP and ONI data for 1999–2024. Productivity was higher in eastern and southern regions and lower in northern and western regions.
