Wildlife Biology, EarlyView.To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Estrogen Receptor Alpha Distribution and Expression in the Social Neural Network of Monogamous and Polygynous Peromyscus. [PDF]
PLoS ONE, 2016 In microtine and dwarf hamsters low levels of estrogen receptor alpha (ERα) in the bed nucleus of the stria terminalis (BST) and medial amygdala (MeA) play a critical role in the expression of social monogamy in males, which is characterized by high ...

Sin Nombre Virus Pathogenesis in Peromyscus maniculatus [PDF]
Journal of Virology, 1999 ABSTRACT Sin Nombre virus (SNV), a member of the Hantavirus genus, causes acute viral pneumonia in humans and is thought to persistently infect mice. The deer mouse, Peromyscus maniculatus , has been identified as the primary reservoir host for SNV. To understand SNV infection of

Wildlife Letters, EarlyView.American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

The molecular basis of high-altitude adaptation in deer mice. [PDF]
PLoS Genetics, 2007 Elucidating genetic mechanisms of adaptation is a goal of central importance in evolutionary biology, yet few empirical studies have succeeded in documenting causal links between molecular variation and organismal fitness in natural populations.

Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus) [PDF]
, 2015 Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals
Integrative Zoology, EarlyView.This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

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 (

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?

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 ...
