Postnatal Development in Peromyscus Maniculatus-Polionotus Hybrids. I, Developmental Landmarks and Litter Mortality [PDF]

open access: yes, 1966
Author Institution: Department of Zoology and Entomology, The Ohio State University, Columbus, OhioNewborn laboratory hybrids of Peromyscus maniculatus and P. polionotus were observed daily from birth to weaning and compared with offspring of each of the

Long‐term monitoring of island night lizards on San Nicolas Island

open access: yesThe Journal of Wildlife Management, Volume 89, Issue 8, November 2025.
We describe the results of long‐term population monitoring of the island night lizard Xantusia riversiana on San Nicolas Island, California, following the species' removal from the U.S. Endangered Species list in 2014. The species' distribution remains largely the same since studies in the 1990s, though small increases in distribution were noted at the

Remote Sensing and Geographic Information Systems: Charting Sin Nombre Virus Infections in Deer Mice

open access: yesEmerging Infectious Diseases, 2000
We tested environmental data from remote sensing and geographic information system maps as indicators of Sin Nombre virus (SNV) infections in deer mouse (Peromyscus maniculatus) populations in the Walker River Basin, Nevada and California.

Use of Track Plates to Quantify Predation Risk at Small Spatial Scales [PDF]

open access: yes, 2005
Spatial heterogeneity in risk is a critical component of predator-prey interactions. However, at small spatial scales, it is difficult to quantify predation risk without altering it.

Heading west: ecology of swift foxes in a novel landscape beyond their range

open access: yesWildlife Biology, Volume 2025, Issue 6, November 2025.
The swift fox Vulpes velox is generally associated with the short‐grass prairie ecosystem of the North American Great Plains; a system that has declined by approximately 50% over the last century. Yet, swift fox populations seem to demonstrate regional variation in trends, with some populations declining while others appear stable to increasing.

Fecal corticosterone metabolite levels in two closely related rodent species in a sub‐Mediterranean environment

open access: yesWildlife Biology, Volume 2025, Issue 6, November 2025.
Glucocorticoids regulate many physiological functions and play an important role in coping with challenging stimuli. The non‐invasive assessment of glucocorticoids is increasingly used as a tool to evaluate individual and population health status in wild animals.

Spatio-temporal patterns in the Hantavirus infection [PDF]

open access: yes, 2002
We present a model of the infection of Hantavirus in deer mouse, Peromyscus maniculatus, based on biological observations of the system in the North American Southwest.

Ecologic Traits Analysis for Identifying Rodent Hosts for Arenavirus and Hepacivirus in the Americas

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Over half of emerging human pathogens originate from wildlife, with rodents serving as key zoonotic hosts. This study used ecological trait‐based models to identify rodent traits associated with arenavirus and hepacivirus infections and detect potential host species across the Americas, our models achieve high predictive accuracy (AUC = 0.92–0.96).

Genome Architecture and Speciation in Plants and Animals

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Sibling rivalry: Males with more brothers develop larger testes

open access: yesEcology and Evolution, 2018
When females mate with multiple partners in a reproductive cycle, the relative number of competing sperm from rival males is often the most critical factor in determining paternity.
