Seasonally variable effects of conspecific odors upon capture of deer mice (Peromyscus maniculatus gambelii).

Embryonic Development of the Deer Mouse, Peromyscus maniculatus

Deer mice, or Peromyscus maniculatus, are an emerging model system for use in biomedicine. P. maniculatus are similar in appearance to laboratory mice, Mus musculus, but are more closely related to hamsters than to Mus. The laboratory strains of Peromyscus have captured a high degree of the genetic variability observed in wild populations, and are more similar to the genetic variability observe...

Native Deer mice (Peromyscus maniculatus) use of invasive grass seed (Ehrharta calycina) in Coastal California

Phenotypic differences in the GnRH neuronal system of deer mice Peromyscus maniculatus under a natural short photoperiod.

The neural mechanisms by which short photoperiod induces gonadal regression among seasonally breeding mammals are not well understood. One hypothesis suggests that the proximate cause of seasonal gonadal regression is a photoperiod-induced modification in GnRH secretion. This hypothesis is indirectly supported by our recent findings using immunocytochemistry which identified specific photoperio...

An island-wide predator manipulation reveals immediate and long-lasting matching of risk by prey.

Anti-predator behaviour affects prey population dynamics, mediates cascading effects in food webs and influences the likelihood of rapid extinctions. Predator manipulations in natural settings provide a rare opportunity to understand how prey anti-predator behaviour is affected by large-scale changes in predators. Here, we couple a long-term, island-wide manipulation of an important rodent pred...

Deer Mouse (Peromyscus maniculatus) Home-Range Size and Fidelity in Sage-Steppe Habitat

—Within a species, home-range size can vary due to factors such as sex, mass, age, and breeding condition of individuals as well as habitat type, food availability, population density, and season. The objectives of this study were to estimate home ranges of deer mice (Peromyscus maniculatus) in sage-steppe habitat and to test the hypothesis that several factors (sex, mass, reproductive status, ...
