Habitat characteristics along spring migration routes of elk, mule deer, and pronghorn in the southern San Juan Mountains

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
We evaluated habitat characteristics of spring migration routes and stopover sites for adult female elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) in the San Juan Mountains (2021–2022) and found species‐specific differences in vegetation structure, terrain, and proximity to land cover types relative to ...

La recherche alpine aujourd’hui [PDF]

open access: yes, 2008
Alpine research benefits from several international coordination networks, only one of which – ISCAR (the International Scientific Committee on Research in the Alps) – works solely in the Alpine arc.

Food Resource Partitioning in Alpine Weasel,Steppe Polecat and Upland Buzzard:Evidence from Stable Isotope Ratios

open access: yes, 2005
Based on mass balance theory and IsoSource program,stable carbon and nitrogen isotopic ratios revealed that small mammals (plateau pika,root vole and plateau zokor) contributed 26.8% and 27.0% and 29.2% to alpine weasel,steppe polecat and upland ...

Temporal stability responses to nitrogen addition in Tibetan alpine grasslands: A community composition perspective

open access: yesJournal of Integrative Agriculture
Plant community composition typically undergoes progressive changes along environmental gradients. However, most experimental studies have focused on individual communities, so it remains unclear how exogenous nutrient inputs affect the stability of ...

Contrasting the Performance of Eight Satellite-Based GPP Models in Water-Limited and Temperature-Limited Grassland Ecosystems

open access: yesRemote Sensing, 2019
Models constitute the primary approaches for predicting terrestrial ecosystem gross primary production (GPP) at regional and global scales. Many satellite-based GPP models have been developed due to the simple algorithms and the low requirements of model

Overgrazing‐Induced Root Carbohydrate Depletion During Winter Dormancy Drives the Decline of Stipa purpurea Populations in the Tibetan Alpine Steppe

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 11516-11532, September 2026.
ABSTRACT Plant carbon allocation and physiology are influenced by overgrazing during the growth period. However, the response of plant physiological processes to overgrazing during winter dormancy remains unclear. We analyzed root physiological processes of Stipa purpurea in winter dormancy across three plots: over grazing (FG), exclusions of 2 years ...

Toward Peace With Nature: Protected Areas Effectively Mitigate Wild Ungulate‐Livestock Competition Despite Spatial Mismatch on the Qinghai‐Tibet Plateau

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Competition for forage between wild ungulates and grazing livestock poses a critical challenge for sustaining grassland ecosystems and pastoral livelihoods. Protected areas (PAs) may mitigate competition, but quantitative multi‐species assessments that simultaneously integrate habitat overlap, forage availability, and conservation ...

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

open access: yesFunctional 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.

Impact of climatic change on alpine ecosystems: inference and prediction [PDF]

open access: yes, 2010
Alpine ecosystems will be greatly impacted by climatic change, but other factors, such as land use and invasive species, are likely to play an important role too. Climate can influence ecosystems at several levels.
