Comparative phylogeography of the plateau zokor (Eospalax baileyi) and its host-associated flea (Neopsylla paranoma) in the Qinghai-Tibet Plateau [PDF]

open access: yes, 2014
Background: Specific host-parasite systems often embody a particular co-distribution phenomenon, in which the parasite’s phylogeographic pattern is dependent on its host.

Field and laboratory studies provide insights into the meaning of day-time activity in a subterranean rodent (Ctenomys aff. knighti), the tuco-tuco. [PDF]

open access: yesPLoS ONE, 2012
South American subterranean rodents (Ctenomys aff. knighti), commonly known as tuco-tucos, display nocturnal, wheel-running behavior under light-dark (LD) conditions, and free-running periods >24 h in constant darkness (DD).

Fungal Diversity and Potential Health Benefits of Mycophagy in Chacma Baboons (Papio ursinus)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 4, April 2026.
Free‐ranging chacma baboons (Papio ursinus) in Nature's Valley, South Africa, of multiple age/sex classes eat diverse fungi (10 identified to species level, 3 to genus level). We assess potential nutritional, medicinal and ecosystem implications of consumption of these fungi based on human and other mammalian mycophagy literature.

Distribution and biology of the ectoparasitic beaver beetle Platypsyllus castoris Ritsema in North America (Coleoptera: Leiodidae: Platypsyllinae) [PDF]

open access: yes, 2006
The distribution and biology of the beaver beetle, Platypsyllus castoris Ritsema, are summarized for North America. In light of the fact that the beetle uses two beaver species as hosts which have seemingly been separated for some five million years on ...

The Naked Mole-Rat: An Unusual Organism with an Unexpected Latent Potential for Increased Intelligence? [PDF]

open access: yes, 2019
Naked mole-rats are eusocial, hairless mammals that are uniquely adapted to their harsh, low-oxygen subsurface habitat. Although their encephalization quotient, a controversial marker of intelligence, is low, they exhibit many features considered tell ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 749-777, April 2026.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Impacts of invasive rats on Hawaiian cave resources

open access: yesInternational Journal of Speleology, 2020
Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus ...
