Sibling rivalry: Males with more brothers develop larger testes

Ecology 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.

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Maporal Hantavirus Causes Mild Pathology in Deer Mice (Peromyscus maniculatus)

Viruses, 2016
Rodent-borne hantaviruses can cause two human diseases with many pathological similarities: hantavirus cardiopulmonary syndrome (HCPS) in the western hemisphere and hemorrhagic fever with renal syndrome in the eastern hemisphere.

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

Wildlife Biology, EarlyView.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.

Peromyscus mice as a model for studying natural variation

eLife, 2015
The deer mouse (genus Peromyscus) is the most abundant mammal in North America, and it occupies almost every type of terrestrial habitat. It is not surprising therefore that the natural history of Peromyscus is among the best studied of any small mammal.

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

First record of the forensically important genus Protopiophila Duda (Diptera: Piophilidae) from South Korea and an integrative framework for forensic identification

Journal of Forensic Sciences, EarlyView.
Abstract The family Piophilidae is of significant forensic importance due to its association with late‐stage decomposition; however, the Korean piophilid fauna remains poorly studied, lacking comprehensive morphological and molecular data. This study reports the first record of the genus Protopiophila Duda from South Korea.

Diet‐based assortative mating through sexual imprinting

Ecology and Evolution, 2019
Speciation is facilitated by “magic traits,” where divergent natural selection on such traits also results in assortative mating. In animal populations, diet has the potential to act as a magic trait if populations diverge in consumed food that ...

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

Emerging 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.
