Extrapolation strategy matters when transferring ecological niche models: new visualization tools for informed decisions

Ecography, Volume 2026, Issue 9, September 2026.
Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

Shiga Toxin-Producing Escherichia coli in Plateau Pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau, China [PDF]

Frontiers in Microbiology, 2016
Shiga toxin-producing Escherichia coli (STEC) are an emerging group of zoonotic pathogens. Ruminants are the natural reservoir of STEC. In this study we determined the prevalence and characteristics of the STEC in plateau pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau, China.

Method comparisons for calculating optimal potassium critical values

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Accurate potassium (K) recommendations are crucial to optimize corn (Zea mays L.) production and minimize economic losses from over‐fertilization. However, there are many methods available to determine the critical soil test value (CSTV) at which K fertilizer should no longer be applied.

Seasonal Variations in the Foraging Strategies of Plateau Pikas (Ochotona curzoniae)

Animals
This study investigates the foraging habits and dietary niche characteristics of plateau pikas (Ochotona curzoniae) by analyzing differences between the cold and warm seasons using stable isotope analysis of carbon and nitrogen in liver, muscle, and fur organs. The results indicated that in the cold season, the plant species incorporated into different

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling

Functional Ecology, Volume 40, Issue 9, Page 2959-2971, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.

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.

Pika burrow and zokor mound density and their relationship with grazing management and sheep production in alpine meadow

Ecosphere, 2020
Plateau pikas (Ochotona curzoniae) and plateau zokors (Myospalax baileyi) occur naturally in the alpine meadow of the Qinghai–Tibet Plateau (QTP). Their feeding and burrowing activities affect plant composition and soil properties (e.g., soil carbon ...

Livestock Depredations and Prevention Strategies to Foster Human‐Carnivore Coexistence in Western Mongolia's High Mountain Systems

Ecology and Evolution, Volume 16, Issue 8, August 2026.
The implementation of visual deterrents (i.e., Foxlights) proved to be effective in reducing the number of night‐time livestock depredations by both snow leopards and wolves. ABSTRACT The decline of large carnivores and the overabundance of livestock practices contribute significantly to ecosystem degradation.

Bare Patches Created by Plateau Pikas Contribute to Warming Permafrost on the Tibet Plateau

Geophysical Research Letters
Abstract Plateau pikas, small mammals native to the Qinghai‐Tibet Plateau (QTP), create bare patches through burrowing. No previous assessment exists on their impact on permafrost. This study fills this gap by simulating hypothetical scenarios in the Three Rivers Headwaters Region of the QTP using the Noah‐MP model for the plant ...

Burrowing-mammal-induced enhanced soil multifunctionality is associated with higher microbial network complexity in alpine meadows

Geoderma
The Plateau pika, a native burrowing mammal in alpine ecosystems, induces significant alterations in both the diversity and functions of the above-ground plant community; however, their effects on the below-ground soil microbial community and its ...
