Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals
Integrative Zoology, EarlyView.We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review
Integrative Zoology, EarlyView.There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

Animal Conservation, EarlyView.This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical

Population structure and vertical stratification of Micoureus paraguayanus (Didelphimorphia, Didelphidae) in lowland atlantic coastal forest fragments, southern Brazil [PDF]
Biotemas, 2006 In order to analyze Micoureus paraguayanus population structure in function of the seasonality and habitats in disturbed forest fragments, a study was carried out on three forest fragments with differences in size, isolation and degrees of deforestation ...

Animal Conservation, EarlyView.Rapid assessment of the delayed impacts of fires on endangered species is essential for accurately guiding conservation efforts. After the fire, surviving Hermann's tortoises (Testudo hermanni) showed only minor behavior alterations, and burnt habitats continued to provide them with essential resources.

Revista Chilena de Historia Natural, 2005 Most of the variation (98.8 %) in basal rate of metabolism (BMR) in 70 species of marsupials is correlated with body mass, although lowland species have higher basal rates than highland species and burrowers have lower basal rates than non-burrowers ...

Cladistics, EarlyView.Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
