Springhares, flying and flightless scaly‐tailed squirrels (Anomaluromorpha, Rodentia) are the squirrely mouse: comparative anatomy of the masticatory musculature and its implications on the evolution of hystricomorphy in rodents

Journal of Anatomy, Volume 244, Issue 6, Page 900-928, June 2024.
The digital dissection of the masticatory musculature of (a) Anomalurus, (b) Idiurus, (c) Zenkerella, and (d) Pedetes reveals a great degree of diversity in morphology. These taxa present a hystricomorphous condition of the skull that largely differs from those of other rodents with an enlarged foramen and reaffirms the significance of the descriptive ...

Abundance estimates of Gunnison's prairie dogs compared to the number of active burrows

Wildlife Society Bulletin, Volume 48, Issue 1, March 2024.
We investigated the relationship between estimates of abundance and active burrow counts for Gunnison's prairie dogs (Cynomys gunnisoni) in the Aubrey Valley, AZ. We found no relationship between any index or esimate of abundance and active burrow counts. Active burrows poorly indexed abundance or density of prairie dogs. Abstract Reliable estimates of

Long‐term occupancy monitoring reveals value of moderate disturbance for an open‐habitat specialist, the Stephens' kangaroo rat (Dipodomys stephensi)

Conservation Science and Practice, Volume 6, Issue 3, March 2024.
From 2005–2018, we monitored populations of Stephen's Kangaroo Rat (SKR) on land actively managed for military training. SKR occupancy and colonization were both positively linked to military disturbance, which facilitated favorable habitat conditions.

Adaptation in brain structure and respiratory and olfactory structures across environmental gradients in African and North American muroid rodents

Integrative Zoology, Volume 19, Issue 1, Page 165-181, January 2024.
Based on 174 cranial 3D images, when considering allometric and phylogenetic constraints, muroid rodents showed potentially adaptive responses to aridity in the bulla, cochlea, paraflocculi, and olfactory lobes of the brain and to high elevation in endocranial volume and the respiratory turbinate bone of the nasal capsule. Abstract Morphometric studies

Ecoepidemiology of Chagas Disease in a Biological Corridor in Southeastern Mexico: A Promising Approach to Understand the Risk of Chagas Disease

Journal of Parasitology Research, Volume 2024, Issue 1, 2024.
Ecoepidemiology is an emerging field that attempts to explain how biotic, environmental, and even social factors influence the dynamics of infectious diseases. Particularly in vector‐borne diseases, the study under this approach offers us an overview of the pathogens, vectors, and hosts that coexist in a given region and their ecological determinants ...
