Tolerance of Warmer Temperatures Does Not Confer Resilience to Heatwaves in an Alpine Herb

open access: yesFrontiers in Ecology and Evolution, 2021
Climate change is generating both sustained trends in average temperatures and higher frequency and intensity of extreme events. This poses a serious threat to biodiversity, especially in vulnerable environments, like alpine systems.

Polar and alpine microbiology [PDF]

open access: yesFEMS Microbiology Ecology, 2012
Scientists, politicians and the general public alike now share the conviction that understanding (micro)biology of polar and alpine systems is of paramount importance to many urgent questions related to global climate, shrinking of polar areas and disappearing of glaciers and other habitats, with the concomitant threat of species extinctions, such as ...

Ecology of the diatom Aulacoseira pusilla in oligotrophic mountain lakes, with implications for paleoclimate reconstructions

open access: yesArctic, Antarctic, and Alpine Research, 2022
Diatoms in lake sediments are used in paleoclimate reconstructions, particularly in treeless areas such as arctic and alpine regions. Some diatom species in the Aulacoseira group are often thought to bloom as lakes turnover (i.e., mix), suggesting links ...

Effects of reindeer density on vascular plant diversity on North Scandinavian mountains

open access: yesRangifer, 2005
We studied the effects of reindeer grazing on species richness and diversity of vascular plants on dolomite influenced low alpine sites in the species rich northern part of the Scandes using 8 sites with different reindeer densities.

Pocket gopher (Thomomys talpoides) soil disturbance peaks at mid-elevation and is associated with air temperature, forb cover, and plant diversity

open access: yesArctic, Antarctic, and Alpine Research, 2018
Burrowing mammals can be ecosystem engineers by increasing soil aeration and erosion and altering the structure of plant communities. Studies that characterize the constraints on the distributions of fossorial mammal disturbances to soil can help predict

Assessment of Artificial and Natural Transport Mechanisms of Ice Nucleating Particles in an Alpine Ski Resort in Obergurgl, Austria

open access: yesFrontiers in Microbiology, 2019
Artificial snow production is a crucial part of modern skiing resorts in Austria and globally, and will develop even more so with changing precipitation patterns and a warming climate trend. Producing artificial snow requires major investments in energy,

Ecological Risk Assessment and Impact Factor Analysis of Alpine Wetland Ecosystem Based on LUCC and Boosted Regression Tree on the Zoige Plateau, China

open access: yesRemote Sensing, 2020
The Zoige Plateau is typical of alpine wetland ecosystems worldwide, which play a key role in regulating global climate and ecological balance. Due to the influence of global climate change and intense human activities, the stability and sustainability ...
