The Journal of Physiology, EarlyView.Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Spatial variation in trophic ecology of small mammals in wetlands: support for hydrological drivers
Ecosphere, 2016 Food webs composed of similar consumers can vary based on nutrient input, habitat structure, and other factors. For wetland‐associated species, fluctuating water levels can potentially affect habitat quality, which in turn can affect trophic diversity ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude
The Journal of Physiology, EarlyView.Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Scientific Reports, 2023 To better understand functional morphological adaptations to high elevation (> 3000 m above sea level) life in both North American and African mountain-associated rodents, we used microCT scanning to acquire 3D images and a 3D morphometric approach to ...

The Journal of Physiology, EarlyView.Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained

Collection of blood from wild‐caught mice (Peromyscus) via submandibular venipuncture
Wildlife Society Bulletin, 2017 ABSTRAC Submandibular venipuncture is a common technique used to harvest whole blood from laboratory‐strain mice, but its effectiveness on wild‐caught Peromyscus spp. has not been formally tested.

How Prospecting for Informed Dispersal Shapes Biodiversity Patterns in a Metacommunity
Ecology and Evolution, Volume 16, Issue 7, July 2026.This study uses an individual‐based model of a small mammal metacommunity to explore how prospecting effort influences competitive exclusion and the resulting dispersal‐diversity relationship. The results show that high prospecting effort can create a hump‐shaped relationship between dispersal and diversity by intensifying competition, a pattern that ...
