Shrub growth in the Alps diverges from air temperature since the 1990s

open access: yesEnvironmental Research Letters, 2021
In the European Alps, air temperature has increased almost twice as much as the global average over the last century and, as a corollary, snow cover duration has decreased substantially.

Plant Responses to Changing Water Supply and Availability in High Elevation Ecosystems: A Quantitative Systematic Review and Meta-Analysis

open access: yesLand, 2021
Climate change is expected to lead to changes to the amount, frequency, intensity, and timing of precipitation and subsequent water supply and its availability to plants in mountain regions worldwide.

Microclimatic effects on alpine plant communities and flower-visitor interactions

open access: yesScientific Reports, 2020
High-alpine ecosystems are commonly assumed to be particularly endangered by climate warming. Recent research, however, suggests that the heterogeneous topography of alpine landscapes provide microclimatic niches for alpine plants (i.e. soil temperatures

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

open access: yesFEBS Open Bio, EarlyView.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

A new species of Bidessus from Anjozorobe-Angavo and a review of Malagasy Bidessus (Coleoptera, Dytiscidae)

open access: yesEuropean Journal of Taxonomy, 2020
We review the species of Bidessus of Madagascar and describe Bidessus anjozorobe sp. nov. from material collected in Anjozorobe forest. Anjozorobe is part of the Anjozorobe-Angavo Protected Area, which is an important corridor of transition forest ...

Functional traits of alpine plant communities show long‐term resistance to changing herbivore densities

open access: yesEcosphere, 2021
Herbivores shape vegetation by suppressing certain plant species while benefitting others. By thus modifying plant species functional composition, herbivores affect carbon cycling, albedo, vegetation structure and species' interactions.

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

open access: yesAdvanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Genetic analysis of the frozen microbiome at 7900 m a.s.l., on the South Col of Sagarmatha (Mount Everest)

open access: yesArctic, Antarctic, and Alpine Research, 2023
Microbial communities in alpine environments >7,500 m.a.s.l. have not been well studied using modern cultivation-independent sequencing approaches due to the challenges and danger associated with reaching such high elevations.

Integration of natural data within a numerical model of ablative subduction: A possible interpretation for the Alpine dynamics of the Austroalpine crust [PDF]

open access: yesJournal of Metamorphic Geology, 2012, 2012
A numerical modelling approach is used to validate the physical and ge- ological reliability of the ablative subduction mechanism during Alpine con- vergence in order to interpret the tectonic and metamorphic evolution of an inner portion of the Alpine belt: the Austroalpine Domain.

Responses and feedback of the Tibetan Plateau’s alpine ecosystem to climate change

open access: yesChinese Science Bulletin, 2019
The Tibetan Plateau, also known as the “third pole of the Earth”, houses a diverse array of alpine-ecosystem types and serves as a critical ecological security shield for China and even for many other regions of Asia. In recent decades, the rapid climate
