Rotifers perform key functions in aquatic food webs and respond to environmental changes, thus providing sensitive indicators of water quality. However, rotifers are small, highly diverse, and difficult to identify for those lacking expertise. Monogononta are the largest taxonomic class of rotifers with over 1500 species described globally, and around ...

Spatiotemporal Dynamics of Streamflow Drought in the Larger Alpine Region
Abstract Streamflow droughts are spatial phenomena that are generally not restricted to individual rivers or catchments. However, many studies spatially limit their drought analysis, for example focusing on a specific country or catchment only, which makes it difficult to study spatiotemporal drought evolution in detail.

Adaptive Significance of Nickel Hyperaccumulation by Plants
Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...

Patterns and Determinants of Mortality in Grey Wolves (Canis lupus)
This systematic review reveals the global patterns and drivers of grey wolf mortality, highlighting the high mortality risk associated with human coexistence for this cursorial carnivore, and reshaping previous knowledge to guide management and conservation strategies.

Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Phenological Shifts in Wood Formation Tracked by Frost Rings Across Two Centuries. [PDF]
Rapid warming is reshaping plant phenology across ecosystems. We present an indirect retrospective approach to infer cambial phenology by analysing the timing and occurrence of frost rings in three Alpine conifers. We found that the cold spells responsible for frost ring formation typically involve temperature dropping below freezing for an average of ...

ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

Origins of Precipitation in the World's Water Towers
Abstract High‐mountain systems act as the planet's vital water towers, sustaining freshwater supplies for billions of people. Climate change is exacerbating hydrological imbalances in these regions, yet the moisture sources maintaining their precipitation—the primary water input—remain poorly quantified.

Hydrogravimetry Enables Quantification of Alpine Groundwater Dynamics
Abstract Groundwater plays a critical role in the functioning of alpine hydrological systems, and its importance is expected to increase under climate change. However, quantification of groundwater processes in these systems remains highly uncertain. Terrestrial time‐lapse gravimetry (TLG) is a geophysical and geodetic technique whose measured variable

Revisiting the Conservation Status of Cobitis taenia in Switzerland Using Environmental DNA
ABSTRACT Freshwater loaches of the genus Cobitis are small benthic fish inhabiting fine sediments in slow‐flowing rivers and vegetated lakes. Due to their small size, low economic value and inconspicuous behaviour, they are rarely studied, and their taxonomy and distribution remain poorly understood.
