Corticosterone Under Experimental Manipulation of Nutrition and Parasite Burden in a Wild Rodent System

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 749-758, August 2026.
ABSTRACT Environmental pressures shape survival and life‐history dynamics partly by triggering the release of glucocorticoids, whose short‐term benefits but long‐term costs make it essential to understand what drives their levels. Here, we used an experimental manipulation of two environmental stressors—food availability and parasite burden—to directly

Is the Cognitive Ability of Fawn‐Footed Mosaic‐Tailed Rat Melomys cervinipes Offspring Related to Mothers’ Care or Cognitive Abilities?

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 785-794, August 2026.
ABSTRACT The cognitive abilities of many non‐human animals have been investigated in recent years; however, outside of laboratory rodent strains, it is largely unknown how direct and indirect genetic factors influence the development of cognition. In a previous study, we found no impact of maternal genetic or non‐genetic effects on problem solving in ...

Distribution and frequency of Vkorc1 polymorphisms in house mice and Norway rats in the northeastern United States

open access: yesPest Management Science, Volume 82, Issue 8, Page 7700-7710, August 2026.
This study assesses the distribution and frequency of Vkorc1 polymorphisms in house mice and Norway rats in northeastern USA. House mice showed higher frequency of Vkorc1 mutations than Norway rats. The A32V and Y139F mutations are first reported in mice, and the L128V is newly reported in Norway rats.

Two Secondary Introductions From a Shared Bridgehead Population Show Evidence of Divergent and Parallel Selection

open access: yesMolecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT Biological invasions offer large‐scale experiments for examining rapid evolution and testing the predictability of adaptive change. Assessing the repeatability of such adaptive responses, however, requires replicated introductions that share similar demographic and environmental contexts. Single introduction events are common during biological

Camera traps reveal cryptic species‐specific seed removal preferences in a seasonal small‐mammal foraging study

open access: yesEcosphere
Seasonal changes in plant–animal interactions, such as seed dispersal and predation, remain poorly understood in temperate ecosystems. We examined seed removal of three woody species (Acer saccharum, Tsuga canadensis, and Lonicera spp.) by small mammals (

Influence of vegetation type and prescribed fire on Peromyscus abundance in a longleaf pine ecosystem

open access: yesWildlife Society Bulletin, 2017
Prescribed fire temporarily can alter food and cover resources for ground‐dwelling wildlife, potentially leading to changes in animal abundance. Small mammals are an important ecosystem component in many terrestrial communities and depend on ground‐level

Rapid Field Immunoassay for Detecting Antibody to Sin Nombre Virus in Deer Mice

open access: yesEmerging Infectious Diseases, 2007
We developed a 1-hour field enzyme immunoassay (EIA) for detecting antibody to Sin Nombre virus in deer mice (Peromyscus maniculatus). The assay specificity and sensitivity were comparable to those of a standard EIA.
