Chromosomal Relationships among Spiny Pocket Mice, Liomys (Heteromyidae), from Mexico [PDF]

open access: yesJournal of Mammalogy, 1999
This study focused on differentially stained karyotypes of the heteromyids Liomys pictus pictus, L. p. plantinarensis, L. spectabilis , and L. irroratus , and described their banding patterns of euchromatin and constitutive heterochromatin to decide if results fit expectations of chromosomal rearrangements leading to karyotypic evolution of the L ...

Microparasite species richness in rodents is higher at lower latitudes and is associated with reduced litter size [PDF]

open access: yes, 2011
Parasite species loads are expected to be higher in the tropics and higher parasite species richness to have cumulative effects on host physiology or demography. Despite being regularly assumed or predicted, empirical evidence on specieslatitude patterns

Caching rodents disproportionately disperse seed beneath invasive grass

open access: yesEcosphere, 2016
Seed dispersal by caching rodents is a context‐dependent mutualism in many systems. Plants benefit when seed remaining in shallow caches germinates before being eaten, often gaining protection from beetles and a favorable microsite in the process ...

An intriguing Y chromosome in Heteromys anomalus (Rodentia, Heteromyidae)

open access: yesHereditas, 2008
Les chromosomes mitotiques de la souris de poche Heteromys anomalus (Rodentia, Heteromyidae) du Venezuela ont été analysés au moyen de coloration conventionnelle et de diverses techniques de baguage. Le caryotype de cette espèce se distingue par un chromosome Y aux propriétés de baguage exceptionnelles.

Functional anatomy of the middle and inner ears of the red fox, in comparison to domestic dogs and cats

open access: yes, 2020
Anatomical middle and inner ear parameters are often used to predict hearing sensitivities of mammalian species. Given that ear morphology is substantially affected both by phylogeny and body size, it is interesting to consider whether the relatively ...

Incisor enamel microstructure places New and Old World Eomyidae outside Geomorpha (Rodentia, Mammalia) [PDF]

open access: yes, 2022
Altres ajuts: CERCA Programme/Generalitat de CatalunyaThe lower incisor enamel microstructure of the fossil rodent family Eomyidae was believed to be three-layered and highly derived but rather uniform throughout the clade.

Group effects of a non‐native plant invasion on rodent abundance

open access: yesEcosphere, 2019
Cheatgrass (Bromus tectorum) is the most prolific invading plant in western North America. Investigations determining the impact of this invasion on population state variables and community dynamics of rodents have largely occurred at the community or ...

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

open access: yesJ Parasitol Res
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 ...

Localized extinction of an arboreal desert lizard caused by habitat fragmentation [PDF]

open access: yes, 2013
We adopted a species' perspective for predicting extinction risk in a small, endemic, and strictly scansorial lizard (Urosaurus nigricaudus), in an old (∿60.
