Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus) [PDF]

open access: yes, 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.

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

open access: yes, 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.

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Patterns of Genetic and Morphological Variation in Deer Mice (Peromyscus Maniculatus) in the Warner Mountains [PDF]

open access: yes, 2011
A previously recognized north-south mitochondrial DNA (mtDNA) break in populations of deer mice, Peromyscus maniculatus, was investigated in Western North America. A 383-bp fragment of the mtDNA control region was analyzed from 107 tissue samples in the

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Genome Sequences of Three Lactobacillus Species Strains of the Stomach of the White-Footed Deermouse (Peromyscus leucopus). [PDF]

open access: yes, 2019
Three colony types of Lactobacillus were isolated from the stomach of LL colony stock Peromyscus leucopus deermice, a reservoir for several human zoonoses.

Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative 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.
