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

Ecology and Evolution, 2021
The enamel microstructure of fossil and extant Geomyoidea (Geomyidae, Heteromyidae) lower incisors incorporates three‐ or two‐layered schmelzmusters with uniserial, transverse Hunter‐Schreger bands having parallel and perpendicular or exclusively ...

The earliest dipodomyine heteromyid in North America and the phylogenetic relationships of geomorph rodents [PDF]

PeerJ, 2023
Dipodomyine heteromyids (kangaroo rats and mice) are a diverse group of arid-adapted ricochetal rodents of North America. Here, a new genus and species of a large dipodomyine is reported from early Miocene-aged deposits of the John Day Formation in ...

Evolutionary Response Patterns of the Rodent <i>TLR</i> Genes to Climatic Factors. [PDF]

Ecol Evol
This study systematically investigates the associations between climatic factors and the evolutionary dynamics of Toll‐like receptor (TLR) genes across 42 rodent species. Our findings demonstrate that temperature‐related climatic variables (Annual Mean Temperature, Mean Diurnal Range, and Max Temperature of Warmest Month) may modulate the evolutionary ...

Distribution and prevalence of Sin Nombre hantavirus in rodent species in eastern New Mexico. [PDF]

PLoS ONE
Orthohantaviruses are diverse zoonotic RNA viruses. Small mammals, such as mice and rats are common chronic, asymptomatic hosts that transmit the virus through their feces and urine.

Fecal metabarcoding of the endangered Pacific pocket mouse (Perognathus longimembris pacificus) reveals a diverse and forb rich diet that reflects local habitat availability [PDF]

Ecology and Evolution, 2023
Information on diet breadth and preference can assist in understanding links between food resources and population growth and inform habitat restoration for rare herbivores.

Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest. [PDF]

Ecol Evol
Collared peccary wallows are used by a diverse assemblage of vertebrates in a Central American tropical wet forest. Wallows had significantly higher vertebrate activity and diversity compared to surrounding forest. Wallow visitors included 13 amphibian, 2 reptile, 11 bird, and 16 mammal species, engaged in behaviors including reproduction, drinking ...

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear. [PDF]

Anat Rec (Hoboken)
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Unraveling abundance from occurrence: Modeling an endangered rodent population with low capture probability. [PDF]

Ecol Appl
Abstract Predicting population abundance while accounting for uncertainty is an essential task for managers of endangered species but is often hindered by the challenge and expense of comprehensive data collection. Many traditional methods for estimating abundance of rare or elusive species are costly and logistically difficult, with occupancy‐based ...

Global Prevalence and Subtype Distribution of Blastocystis sp. in Rodent Populations: A Systematic Review and Meta-Analysis. [PDF]

Vet Med Sci
Overall, 16% of rodents worldwide were infected with Blastocystis sp. (95% CI: 12.6%–20.2%). Rodents host various Blastocystis sp. subtypes (STs), including ST1‐ST8, ST10, ST13, ST15 and ST17. The most commonly reported STs in rodents globally were ST4, ST5, ST1 and ST3.

Springing into action: Comparing escape responses between bipedal and quadrupedal rodents. [PDF]

Ecol Evol
The findings of this study suggest that enlarged hindlimbs improve escape performance by allowing rodents to more efficiently utilize vertical jumping as an antipredator escape response. Abstract Predation is a fundamental selective pressure on animal morphology, as morphology is directly linked with physical performance and evasion. Bipedal heteromyid
