Modelling marsupial mastication: The biomechanical bite model of the Linnaeus's mouse opossum Marmosa murina (Marsupialia, Didelphidae)

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1187-1203, December 2025.
The marsupial masticatory apparatus has rarely been studied until recently, mainly in Australasian species. We therefore reconstructed the maximum bite forces of the South American Linnaeus's mouse opossum Marmosa murina using in vivo bites, specimen dissections, and 3D static equilibrium of the jaw muscles.

High Elevation Occurrences of Jaguars (Panthera onca, Linnaeus 1758) (Mammalia, Felidae) in Northwestern Mexico, With a Record of Collaborative Interactions

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Jaguars in the northern end of their distribution have recently become the center of conservation efforts; however, the State of Chihuahua has been underrepresented in monitoring projects. We present five new records of jaguars in high altitudes as well as the first evidence of two jaguars exhibiting cooperative behavior in Mexico.

Effectiveness of temporal matching in ecological niche models: Insights for a low‐dispersing species

open access: yesEcosphere, Volume 16, Issue 8, August 2025.
Abstract Ecological niche models, crucial for estimating the potential distribution of species under global change, can face reduced accuracy when the timing of occurrence data does not align with the environmental data. One solution is to ensure a close temporal match between the environment and the observation date.

Network dynamics revealed from eDNA highlight seasonal variation in urban mammal communities

open access: yesJournal of Animal Ecology, Volume 94, Issue 8, Page 1587-1602, August 2025.
Our novel study applied eDNA to track seasonal shifts in urban mammal communities, revealing changes in diversity and species interaction networks across 21 urban parks in Detroit. We highlight the influence of park size and human activity on biodiversity, demonstrating the utility of eDNA for urban conservation and wildlife management.

Patterns of arboreal and terrestrial space use by non-volant small mammals in an Araucaria forest of southern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2014
Despite the advances in the techniques for researching arboreal small mammals, detailed ecological data, such as habitat use patterns, are practically nonexistent for many species.

Geographic variation in Caluromys derbianus and Caluromys lanatus (Didelphimorphia: Didelphidae)

open access: yesZoologia (Curitiba), 2015
We analyzed the geographic variations in the shape and size of the cranium and mandible of two woolly opossums, Caluromys derbianus and Caluromys lanatus. Using geometric morphometrics we analyzed 202 specimens of C.

A comparison of abundance estimators for small mammal populations

open access: yesZoologia (Curitiba), 2013
A major difficulty in the application of probabilistic models to estimations of mammal abundance is obtaining a data set that meets all of the assumptions of the model.
