YOLO-Pika: a lightweight improved model of YOLOv8n incorporating Fusion_Block and multi-scale fusion FPN and its application in the precise detection of plateau pikas

Frontiers in Plant Science
The plateau pika (Ochotona curzoniae) is a keystone species on the Qinghai–Tibet Plateau, and its population density—typically inferred from burrow counts—requires rapid, low-cost monitoring.

Conserving Rodent Pests in Transition Toward Endangered Status

Integrative Zoology, EarlyView.
Rodent control invariably takes place in the context of ecosystems heavily modified by agriculture. Together, they are potent drivers of rodent decline and endangerment. Nineteen percent of 2349 rodent species evaluated in the IUCN Red List of threatened species are of some conservation concern.

Effect of Plateau Pika Disturbance on Plant Aboveground Biomass of Alpine Meadows at Two Different Scales

Plants, 2022
Disturbance by small burrowing herbivores often has an impact on plant aboveground biomass of grassland because it makes grasslands into a mosaic of discrete vegetated surfaces and bare soil patches.

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

Medical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Effects of Plateau Pika Disturbance on the Spatial Heterogeneity of Vegetation in Alpine Meadows

Frontiers in Plant Science, 2021
Herbivory is one of the important factors that influence spatial heterogeneity of vegetation in grasslands. In this study, we focused on plateau pika (Ochotona curzoniae) to investigate the effects of the presence of small semi-fossorial herbivores and ...

DataSheet1_Differential Expression of Metabolism-Related Genes in Plateau Pika (Ochotona curzoniae) at Different Altitudes on the Qinghai–Tibet Plateau.docx

, 2022
According to life history theory, animals living in extreme environments have evolved specific behavioral and physiological strategies for survival. However, the genetic mechanisms underpinning these strategies are unclear.

A Comparison of the Gut Microbiome of Two Sympatric Macropods Along an Urbanisation Gradient in Tasmania

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Our study is the first to explore how macropod gut flora vary across levels of urbanisation, exploring the faecal microbiomes of the red‐bellied pademelon (Thylogale billardierii) and the red‐necked wallaby (Notamacropus rufogriseus rufogriseus). There is some evidence of urbanisation's impacts on the macropod microbiome, although there appear to be ...

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 ...

Translocation and deterrence as tools for conservation and management of Columbian ground squirrels (Urocitellus columbianus) in a national park

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Our study evaluates two non‐lethal methods for managing Columbian ground squirrels in Jasper National Park, Alberta, Canada. We demonstrate that translocated squirrels exhibited lower survival than controls and that a deterrence methodology that includes blocking burrows may be an appropriate alternative, especially when combined with other tools ...
