Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

open access: yesThe 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 ...

Micofagia por roedores en un bosque templado del centro de México

open access: yesRevista Mexicana de Biodiversidad, 2012
La micofagia por roedores en hongos hipogeos ha sido documentada en diversos ecosistemas a nivel mundial, sin embargo el consumo de hongos epigeos por este grupo ha sido pobremente estudiado.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

open access: yesThe 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 ...

The Bold, Silent Type: Predictors of Ultrasonic Vocalizations in the Genus Peromyscus

open access: yesFrontiers in Ecology and Evolution, 2018
An ongoing question related to the evolution of monogamy is how behavioral traits that characterize individuals in monogamous species evolve, and whether monogamy influences the evolution of these traits. One of the most important models for the study of

Counter-gradient variation and the expensive tissue hypothesis explain parallel brain size reductions at high elevation in cricetid and murid rodents

open access: yesScientific 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 influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

open access: yesThe 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

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Collection of blood from wild‐caught mice (Peromyscus) via submandibular venipuncture

open access: yesWildlife 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.
