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 ...

Genetic relationships of Caribbean lowland spiny pocket mice (Heteromys desmarestianus: Rodentia; Heteromyidae): evidence of a distinct mitochondrial lineage [PDF]

, 2020
Genetic studies provide important insights into the evolutionary history and taxonomy of species, allowing us to identify lineages dif-ficult to distinguish morphologically. The relationships among species in the genus Heteromys have been in flux as new

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

Las precipitaciones conducen la actividad reproductiva en machos de Microcavia australis en el desierto del Monte. [PDF]

, 2016
Desert areas represent heterogeneous environments where animals must reproduce under extreme conditions, and where a combination of environmental factors may contribute to trigger or inhibit reproduc­tion. Microcavia australis is a caviomorph rodent that

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

Mammalian Facial Muscles: Their Evolution, Function, Diversity, & Study Through Comparative Methods [PDF]

, 2022
Within the great diversity of living vertebrates, mammals alone are distinguished by the presence of facial muscles. These delicate sheets of muscle are distributed in superficial layers of the face and neck and are responsible for critical everyday ...

Diversity and distribution of small terrestrial rodents along a disturbance gradient in montane Costa Rica

Revista de Biología Tropical, 1998
A total of 389 rodent captures in five unequally disturbed habitats in a Costa Rican montane cloud forest corresponded to 185 individuals (seven species, two families).
