Sin nombre virus and rodent species diversity: a test of the dilution and amplification hypotheses. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Species diversity is proposed to greatly impact the prevalence of pathogens. Two predominant hypotheses, the "Dilution Effect" and the "Amplification Effect", predict divergent outcomes with respect to the impact of species diversity.

Lice, Mites, and Ticks of Southeastern Wisconsin Mammals [PDF]

open access: yes, 2017
Seventeen species of southeastern Wisconsin mammals were found to 6e infected with arthropod ectoparasites other than fleas. One host species was infested with one species of biting lice (Mallophaga), five with five species of sucking lice (Anoplura ...

PrPCWD lymphoid cell targets in early and advanced chronic wasting disease of mule deer [PDF]

open access: yes, 2002
Up to 15% of free-ranging mule deer in northeastern Colorado and southeastern Wyoming, USA, are afflicted with a prion disease, or transmissible spongiform encephalopathy (TSE), known as chronic wasting disease (CWD).

Development and Characterization of a Sin Nombre Virus Transmission Model in Peromyscus maniculatus

open access: yesViruses, 2019
In North America, Sin Nombre virus (SNV) is the main cause of hantavirus cardiopulmonary syndrome (HCPS), a severe respiratory disease with a fatality rate of 35⁻40%. SNV is a zoonotic pathogen carried by deer mice (Peromyscus maniculatus), and few

Behavioral restriction, lorazepam, and escitalopram uniquely influence the expression of naturalistic stereotypy in deer mice: perspectives on anxiety- and compulsive-like behavior

open access: yesFrontiers in Behavioral Neuroscience, 2022
Introduction: Stereotypical expression in laboratory-housed rodents can be explained by different motivational, coping, and motor dysfunction theories.

Lyme Disease Agent Reservoirs Peromyscus leucopus and P. maniculatus Have Natively Inactivated Genes for the High-Affinity Immunoglobulin Gamma Fc Receptor I (CD64)

open access: yesPathogens, 2023
The abundant and widely distributed deermice Peromyscus leucopus and P. maniculatus are important reservoirs for several different zoonotic agents in North America.

High-elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta. [PDF]

open access: yesJ Physiol
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 (

Variations in Ixodes ricinus Density and Borrelia Infections Associated with Cattle Introduced into a Woodland in The Netherlands [PDF]

open access: yes, 2008
The effect of introduced large herbivores on the abundance of Ixodes ricinus ticks and their Borrelia infections was studied in a natural woodland in The Netherlands. Oak and pine plots, either ungrazed or grazed by cattle, were selected.

Interspecific variation in cooperative burrowing behavior by Peromyscus mice

open access: yesEvolution Letters, 2022
Animals often adjust their behavior according to social context, but the capacity for such behavioral flexibility can vary among species. Here, we test for interspecific variation in behavioral flexibility by comparing burrowing behavior across three ...
