High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Persistent effects of pair bonding in lung cancer cell growth in monogamous Peromyscus californicus

eLife, 2021
Epidemiological evidence suggests that social interactions and especially bonding between couples influence tumorigenesis, yet whether this is due to lifestyle changes, homogamy (likelihood of individuals to marry people of similar health), or directly ...

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

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 ...

Ejaculate Investment in a Promiscuous Rodent, \u3cem\u3ePeromyscus maniculatus\u3c/em\u3e: Effects of Population Density and Social Role [PDF]

, 2006
Questions: How does average male investment in ejaculates vary with changing population density (and thus with the risk of sperm competition) in a promiscuous species? Do individual male investment strategies vary with population density?

Reviewing the effects of food provisioning on wildlife immunity [PDF]

, 2018
While urban expansion increasingly encroaches on natural habitats, many wildlife species capitalize on anthropogenic food resources, which have the potential to both positively and negatively influence their responses to infection.

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 ...

Genetic Diversity and Distribution of Peromyscus-Borne Hantaviruses in North America

Emerging Infectious Diseases, 1999
The 1993 outbreak of hantavirus pulmonary syndrome (HPS) in the southwestern United States was associated with Sin Nombre virus, a rodent-borne hantavirus; The virus' primary reservoir is the deer mouse (Peromyscus maniculatus).

Question the Mark: A Review and Assessment of Bat Marking Practices

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

Mensural Discrimination of the Skulls of Arkansas Peromyscus [PDF]

, 1983
Twelve parameters were measured on skulls of four species of Peromyscus from Arkansas. Univariate statistical tests, multivariate analyses of variance, and principal axis factor analyses were performed on the data set and/or subsets in a search for ...
