Variação intraespecífica da cor da pelagem de uma espécie de pequeno roedor sul-americano [PDF]

open access: yes, 2016
Intra-specific color variation is often underestimated by researchers, and among mammalian species, intra-specific differences in coloration are poorly documented for most species.

Dietary adaptations along the northern limit of distribution: what does the smooth snake Coronella austriaca eat in Norway? Metabarcoding of stomach content and visual analysis of faeces

open access: yesWildlife Biology, EarlyView.
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...

Mus spretus (Rodentia: Muridae) [PDF]

open access: yesMammalian Species, 2009
Mus spretus Lataste, 1883, is a small, wild (noncommensal) murine with a rounded muzzle and small eyes and ears. This species, commonly called the western Mediterranean mouse, is distributed throughout Portugal across all but the northern fringe of Spain into the southern region of France.

Evidence for parallel development of ever-growing molars in Early Pleistocene rodents from southern Spain and their paleoenvironmental implications

open access: yesActa Palaeontologica Polonica, 2023
In this paper, we present a detailed survey on the rodent fauna from the site of Barranco de los Conejos (Guadix-Baza Basin, southern Spain). Its rodent fauna is composed of three arvicolines (Orcemys giberti, Manchenomys oswaldoreigi, and Tibericola ...

Fast Compatibility Testing for Phylogenies with Nested Taxa [PDF]

open access: yesarXiv, 2016
Semi-labeled trees are phylogenies whose internal nodes may be labeled by higher-order taxa. Thus, a leaf labeled Mus musculus could nest within a subtree whose root node is labeled Rodentia, which itself could nest within a subtree whose root is labeled Mammalia.

Small mammals feeding on hypogeous fungi [PDF]

open access: yes, 2014
The spores stay viable after passing through the animal gut, and in some cases their ability to germinate and form mycorrhiza is enhanced after leaving the intestine.

Radiological Landmarks as an Aid in the Interpretation of Rodent Skull Extra‐Oral Projections

open access: yesZoo Biology, EarlyView.
ABSTRACT Knowledge of the radiographic anatomy of rodent skulls is essential for accurately interpreting extra‐oral radiographs, a non‐invasive diagnostic tool commonly used in veterinary practice. Due to the complexity of the skull and the potential for distortion in two‐dimensional views, a systematic evaluation of anatomical structures is necessary.

Navigating Methodological Trade‐Offs in eDNA Metabarcoding Biodiversity Monitoring: Insights From a Mediterranean Watershed

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metabarcoding technologies promise significant advances in biodiversity monitoring, yet their application requires extensive optimisation and standardisation. Recent research demonstrated that increased sampling and analytical efforts are needed to improve biodiversity estimates, though fully optimising study designs ...

Clinical, pathological and immunohistochemical characterization of spontaneous neoplasms in pet rodents in Northeastern Brazil [PDF]

open access: yesPesquisa Veterinária Brasileira
: In the last decade, there has been a significant increase in the demand for small rodents such as hamsters, guinea pigs, rats, and mice to be kept as pets. Consequently, the veterinary care provided to these animals has also increased.

Fit of Fossils and Mammalian Molecular Trees: Dating Inconsistencies Revisited [PDF]

open access: yesarXiv, 2008
Divergence time estimation requires the reconciliation of two major sources of data. These are fossil and/or biogeographic evidence that give estimates of the absolute age of nodes (ancestors) and molecular estimates that give us estimates of the relative ages of nodes in a molecular evolutionary tree. Both forms of data are often best characterized as
