Rapid Changes in Retrogressive Thaw Slump Dynamics in the Russian High Arctic Based on Very High‐Resolution Remote Sensing

Geophysical Research Letters
We used very high‐resolution satellite images to map the development of retrogressive thaw slumps (RTS) at six sites in the Russian High Arctic for the period 2011 to 2020.

A Generic Approach to Creating a National Soil Security Strategy

Sustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.

RETRACE Project: How to Enhance Resilience to Climate Risks in Pacific and Arctic Indigenous Communities?

Sustainable Development, EarlyView.
ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

Using Visual Systems Mapping to Improve Transparency and Comparability of Life Cycle Assessment Baseline Scenarios

Systems Engineering, EarlyView.
ABSTRACT Visual systems mapping is a systems engineering approach used to represent complex processes and interactions. This study evaluates its application for documenting assumptions in life cycle assessment (LCA) baseline scenarios. In LCA, the baseline or reference case represents the business as usual system against which changes in impacts (e.g.,

Evaluating of ground surface freeze–thaw and the interrelationship with vegetation cover on the Qinghai-Xizang Plateau

Geoderma
The annual frequency of ground surface freeze–thaw (AFGSFT) on the Qinghai-Xizang Plateau (QXP) is one of the most prominent features of the high plateau ground surface processes.

Banking Biodiversity: Ex Vivo Solutions for a Planet in Crisis

Zoo Biology, EarlyView.
Genetic diversity is being lost faster than it can be cataloged. Biobanking preserves cells, gametes, and DNA as recoverable material for future conservation use, and delivers most when collections are established proactively rather than deployed once populations are already critically depleted.

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study

Journal of Animal Ecology, EarlyView.
Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Carbon flow to generalist predators shifts between plant‐ and fungal‐derived resources in highly seasonal ecosystems

Journal of Animal Ecology, EarlyView.
Using amino acid isotope fingerprinting, Sagi et al. show how Arctic wolf spiders shift between plant‐ and microbe‐based energy sources with changes in body size and plant productivity. This reveals how environmental conditions and consumer traits jointly shape carbon flow and link green and brown food webs in rapidly changing ecosystems.
