Social Organisation Predicts Lifespan in Mammals

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Using Bayesian phylogenetic analyses of 1436 mammal species, we show that pair‐living and group‐living species have longer maximum lifespans than solitary species after accounting for body mass and phylogeny. Differences between pair‐ and group‐living species were small, and activity period showed weak associations.

Tree shrews as a new animal model for systemic sclerosis research

Frontiers in Immunology
ObjectiveSystemic sclerosis (SSc) is a chronic systemic disease characterized by immune dysregulation and fibrosis for which there is no effective treatment. Animal models are crucial for advancing SSc research. Tree shrews are genetically, anatomically,

Distinct Frequency Specialization for Detecting Dark Transients in Humans and Tree Shrews

Cell Reports, 2018
Summary: Despite well-known privileged perception of dark over light stimuli, it is unknown to what extent this dark dominance is maintained when visual transients occur in rapid succession, for example, during perception of moving stimuli.

Vertebrate Natural History Notes from Arkansas, 2017 [PDF]

, 2017
Because meaningful observations of natural history are not always part of larger studies, important pieces of information often are unreported. Small details, however, can fills gaps in understanding and also lead to interesting questions about ...

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Low cholesteryl ester transfer protein and phospholipid transfer protein activities are the factors making tree shrew and beijing duck resistant to atherosclerosis

Lipids in Health and Disease, 2010
Background Tree shrew and beijing duck are regarded as animal models resistant to atherosclerosis (AS). This study was carried out to discover the potential mechanism. Methods Blood samples were collected from healthy men and male animals.

On the Relation Between Receptive Field Structure and Stimulus Selectivity in the Tree Shrew Primary Visual Cortex [PDF]

, 2017
There are notable differences in functional properties of primary visual cortex (V1) neurons among mammalian species, particularly those concerning the occurrence of simple and complex cells and the generation of orientation selectivity. Here, we present

Chinese Pangolin Changes Local Vertebrate Assemblages and Contributes to Their Interspecific Interactions by Burrowing and Revisitation

Integrative Zoology, Volume 21, Issue 3, Page 499-510, May 2026.
In this study, we systematically analyzed the utilization patterns of Chinese pangolin burrows by sympatric species in Guangdong Province, China, including differences in species composition using burrow mounds and burrow tunnels. We found that repeated visits to burrows by Chinese pangolin promoted the use of burrows by sympatric species, suggesting ...

Organic farms as refuges for small mammal biodiversity in agro ecosystems [PDF]

, 2011
Habitat fragmentation, the process by which relatively continuous habitats is broken into smaller pieces, occurs in natural systems but is to a high degree also human-induced through landscape use.

Bergmann's and Allen's Rules in European Shrews (Genus Sorex): Insights From 3D Morphological Models

Journal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Although Bergmann's and Allen's rules are widely recognized, their study in micromammals such as shrews remains scarce. Ecogeographical rules are crucial for anticipating organismal responses to environmental change, as they describe morphological variation across climatic gradients and may offer predictive value under climate change ...
