Re-evaluating climate as the best predictor of pika (Ochotona princeps) surface activity [PDF]

open access: yes, 2016
Alpine and subalpine ecosystems are expected to experience a disproportionate amount of warming in the coming decades. Rising temperatures in these ecosystems threatens biodiversity and water resources globally. The American pika (Ochotona princeps) is a

Faecal Pellets as a Non‐Invasive Source for DNA‐Based Monitoring of Lagomorphs

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
We review the use of faecal DNA to investigate wild lagomorph populations. In so doing, we examined ASPECTS like sampling design, storage medium, DNA extraction protocol, molecular markers, and the final yield of the analysis. We provide a valuable starting point for researchers who intend to conduct non‐invasive genetic investigations.

Assessment of Ruminal Bacterial and Archaeal Community Structure in Yak (Bos grunniens) [PDF]

open access: yes, 2017
The aim of this study was to determine the microbial community composition in the rumen of yaks under different feeding regimes. Microbial communities were assessed by sequencing bacterial and archaeal 16S ribosomal RNA gene fragments obtained from yaks (

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

open access: yesEcosphere, 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 ...

Hibernation Shifts in Gut Microbiota Composition and Metabolic Function in the Chinese Horseshoe Bat (Rhinolophus sinicus)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The composition and dynamics of gut microbial community structure in Rhinolophus sinicus, employing 16S rRNA amplicon sequencing, are conducted to investigate the effects of physiological status (winter hibernation versus summer activity) on gut microbiota composition.

Architecture Characteristics of Burrow System of Plateau Pika, Ochotona curzoniae

open access: yesPakistan Journal of Zoology, 2018
Burrows serve many functions for animals by providing a place for rearing young, sleeping, hibernation, food storage, protection from predators and extreme environment, and the function of burrows varies with the degree of burrow complexity. We studied the burrow architecture (length, internal dimensions, fractal dimension of tunnel systems, number of ...

Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities [PDF]

open access: yes, 2011
Part of Focus on Dynamics of Arctic and Sub-Arctic Vegetation Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1)

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are
