Biomechanical adaptations for burrowing in the incisor enamel microstructure of Geomyidae and Heteromyidae (Rodentia: Geomyoidea)

open access: yesEcology and Evolution, Volume 11, Issue 14, Page 9447-9459, July 2021., 2021
Incisors of fossil and extant Geomyidae (pocket gophers) and Heteromyidae (pocket mice, spiny pocket mice, kangaroo mice, kangaroo rats) show enamel with built‐in failure prevention related to chisel‐tooth digging. This distinctive microstructure character strengthens the joint phylogenetic origin of these North American rodents because it is absent in

Monitoring of SARS‐CoV‐2 infection in mustelids

open access: yesEFSA Journal, Volume 19, Issue 3, March 2021., 2021
Abstract American mink and ferret are highly susceptible to severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), but no information is available for other mustelid species. SARS‐CoV‐2 spreads very efficiently within mink farms once introduced, by direct and indirect contact, high within‐farm animal density increases the chance for transmission.

Evolution of protamine genes and changes in sperm head phenotype in rodents [PDF]

open access: yes, 2016
Little is known about the genetic basis of evolutionary changes in sperm phenotype. Postcopulatory sexual selection is associated with differences in protamine gene sequences and promoters and is a powerful force acting on sperm form and function ...

Risk assessment of nitrate and nitrite in feed

open access: yesEFSA Journal, Volume 18, Issue 11, November 2020., 2020
Abstract The European Commission asked EFSA for a scientific opinion on the risks to animal health related to nitrite and nitrate in feed. For nitrate ion, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) identified a BMDL10 of 64 mg nitrate/kg body weight (bw) per day for adult cattle, based on methaemoglobin (MetHb) levels in animal's ...

Cricetinae G. Fischer 1817

open access: yes, 1993
Subfamily Cricetinae G. Fischer, 1817. Mém. Soc. Imp. Nat. Moscow, 5:372. COMMENTS: Reviewed by Corbet (1978c, 1984), who (1978c:88) noted that "generic divisions within the group are rather unstable and a fresh, comprehensive classification is required," a conclusion we echo after studying specimens and literature. One of these divisions is Cricetulus,
