Metal Accumulation, Liver Histopathology, and Human Health Risk Assessment Across Different Trophic Guilds in a Mining‐Affected Neotropical River

Journal of Applied Toxicology, EarlyView.
ABSTRACT Metal pollution in aquatic environments represents a recurring global concern; however, traditional paradigms often assume linear bioaccumulation patterns that may fail under catastrophic contamination scenarios. This study evaluated metal concentrations in water, sediment, and tissues of 10 fish species from different trophic guilds in the ...

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.

Embryonic Development in Two High‐Elevation Oviparous Lizard Species: Contrasting Strategies for Coping With Cold Climates

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Understanding how species respond to local climates is crucial for predicting their responses to climate change. The cold climate of high elevations constitutes a physiological challenge for reptiles, especially during the embryonic stages of oviparous species, because embryos have limited ability to thermoregulate behaviorally. To examine how

Body Size and Habitat Association as Determinants for Water Balance, Temperature Relations, and Behavioral Performance in Leptodactylid Frogs

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The association between species' habitat preferences (e.g., aquatic, terrestrial, arboreal) and traits related to body temperature regulation and water balance has been relatively well studied in anurans. However, whether such associations hold for species occupying the same general habitat while differing in other relevant functional ...
