Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

open access: yesWildlife Biology, Volume 2026, Issue 3, May 2026.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

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

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 989-1004, April 2026.
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 ...

Rapid Enzyme-Linked Immunosorbent Assay for the Detection of Hantavirus-Specific Antibodies in Divergent Small Mammals

open access: yesViruses, 2014
We assessed the utility of an enzyme-linked immunosorbent assay (ELISA) for the detection of hantavirus-specific antibodies from sera of Oligoryzomys longicaudatus, the principal reservoir of Andes virus (ANDV), using an antigen previously developed for ...

Abundance–Occupancy Relationships are Informed by Species Temporal Occupancy

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Understanding how species spatial and temporal distributions are related to abundance is fundamental to ecology. Indeed, the relationship between species spatial occupancy and abundance has been investigated across taxa and environments. Less studied, is how species temporal occupancy may inform the spatial abundance–occupancy relationship.

Collection of blood from wild‐caught mice (Peromyscus) via submandibular venipuncture

open access: yesWildlife Society Bulletin, 2017
ABSTRAC Submandibular venipuncture is a common technique used to harvest whole blood from laboratory‐strain mice, but its effectiveness on wild‐caught Peromyscus spp. has not been formally tested.

Ejaculate Investment in a Promiscuous Rodent, \u3cem\u3ePeromyscus maniculatus\u3c/em\u3e: Effects of Population Density and Social Role [PDF]

open access: yes, 2006
Questions: How does average male investment in ejaculates vary with changing population density (and thus with the risk of sperm competition) in a promiscuous species? Do individual male investment strategies vary with population density?

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.

Vertebrate community composition and activity at giant otter latrines in the northern Pantanal

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Mustelids and other terrestrial carnivores use communal latrines where feces and urine serve as olfactory cues for territory demarcation and intraspecific communication. These strong scent cues may also influence the broader vertebrate community, either acting as an attractant for species in search of food or as a warning of predator presence.

Diffusion and Home Range Parameters from Rodent Population Measurements in Panama

open access: yes, 2005
Simple random walk considerations are used to interpret rodent population data collected in Hantavirus-related investigations in Panama regarding the short-tailed cane mouse, \emph{Zygodontomys brevicauda}.

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.
