Stability of alpine meadow ecosystem on the Qinghai-Tibetan Plateau
Chinese Science Bulletin, 2006 The meadow ecosystem on the Qinghai-Tibetan Plateau is considered to be sensitive to climate change. An understanding of the alpine meadow ecosystem is therefore important for predicting the response of ecosystems to climate change. In this study, we use the coefficients of variation (Cv) and stability (E) obtained from the Haibei Alpine Meadow ...

Integrative Zoology, EarlyView.In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Integrative Zoology, EarlyView.Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate

Integrative Zoology, EarlyView.The graphical abstract illustrates the comprehensive workflow of our study, from the deployment of infrared cameras at sites with high activity of four large carnivores, through data collection and assessment of activity patterns, to the prediction of time periods with potential human–large carnivore conflicts and the proposal of corresponding ...

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities
Integrative Zoology, EarlyView.Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change
Integrative Zoology, EarlyView.Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Integrative Zoology, EarlyView.This study provides novel insights into the biogeographic patterns of the Sichuan golden snub‐nosed monkey, particularly in terms of habitat suitability and spatial‐use strategies. We found that habitat suitability has expanded over the past decade, with substantial shifts in the environmental factors influencing habitat suitability, from terrain and ...

Conservation Science and Practice, EarlyView.We assessed shepherds' attitudes toward wolves and their perceptions of herd protection measures. Negative views were common among hobby shepherds and those affected by surplus killings, while professional and part‐time shepherds, especially those with minor attack experiences, held more neutral or positive attitudes.

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees
Ecological Entomology, EarlyView.We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...
