Evolution shapes ecosystem resilience through spatial self-organization.

Drylands are globally widespread and ecologically important but vulnerable to climate change. Many exhibit spatially self-organized vegetation patterns that enhance resilience by enabling vegetation to reorganize their patterns under drying, thereby optimizing water use and maintaining productivity. Plants can also undergo evolution in response to environmental change. Although both spatial self-organization and rapid evolution are fundamental mechanisms of resilience, their interaction remains

Global grassland productivity and carbon storage benefit from functional diversity under climate change.

Functional diversity plays an important role for ecosystem services of managed grasslands such as their gross primary productivity (GPP) and soil organic carbon (SOC) stocks. Yet vegetation models assessing functional diversity have been limited to small spatial scales. We used the Lund-Potsdam-Jena managed land (LPJmL) competitor stress-tolerant ruderal (CSR) model to assess the role of functional diversity for managed grassland GPP and SOC under climate change at the global scale. LPJmL-CSR si

Fragmentation outweighs forest cover in shaping land surface temperature across half of global forests.

Forests are widely recognized for their significant role in climate change mitigation. Global landscape-scale assessments have focused mainly on how forest cover (FC) affects temperature. Yet, changes in forest area are generally accompanied by altered fragmentation, and both the independent effect of fragmentation on forest thermal environments and its contribution relative to FC remain insufficiently understood. We disentangled the respective relationships of fragmentation and FC with land sur

Global greenhouse gas cobenefits of US irrigated agriculture.

Land use and land conversion for agriculture contribute nearly a quarter of global greenhouse gas (GHG) emissions, making the sector a key priority for emissions reductions. Crop yields are one factor that modulate agricultural land demand, with, all else equal, global land use change increasing with yield declines and decreasing with yield gains. Therefore, agricultural practices drive both direct, on-farm emissions, and indirect land use change emissions through yield effects. Here, we couple

Manure to insect farming for feed mitigates nitrogen and greenhouse gas emissions.

Livestock manure is nutrient-rich and represents a promising feedstock for insect farming, with insect protein offering a high-quality alternative to conventional crop-based livestock feed. This pathway has substantial potential to mitigate nitrogen (N) and greenhouse gas (GHG) emissions from livestock systems. Here, we integrate global livestock models with trade, land-use, and cost-benefit analysis to quantify the environmental and economic implications of manure-to-insect conversion while ens

Climate mitigation contributes more to population persistence than evolutionary adaptation in a long-lived seabird.

Evolutionary rescue-the process by which adaptive evolution prevents population extinction following environmental deterioration -is frequently proposed as a buffer against biodiversity loss under climate change, yet its capacity to alter future population trajectories is rarely assessed quantitatively. Most forecasts of evolutionary rescue rely on simplified demographic models, focus on a single adaptive trait, and explore hypothetical environmental scenarios rather than standardized climate pa

Earthquake-triggered cascading hazards under Arctic amplification.

Arctic warming is reshaping permafrost and glacierized terrains, potentially changing their natural hazards in response to seismic shaking. On 10 March 2025, a Mw 6.5 oceanic transform fault earthquake near Jan Mayen Island in the Arctic Ocean triggered a large rock avalanche that buried part of the Kjerulf Glacier, generating infrasound signals and glacier calving. Using seismic, Global Navigation Satellite System data, infrasound records, satellite imagery, and long-term climatological records

Evolution of flowering phenology over 44 years of climate change.

Evolution is expected to be crucial for the persistence of some populations exposed to changing climate, but demonstrations of rapid evolution in wild populations associated with ongoing climate change are scarce. Inferences about possible adaptive responses rest heavily on "space-for-time" approaches that are fraught with assumptions that are difficult to verify. In contrast, resurrection experiments offer a direct method to observe evolutionary changes over time but rarely span the periods of

Rising plant extinction rates on European mountain summits.

Climate change increases plant species richness in alpine ecosystems. However, to what extent this diversity enrichment masks extinction dynamics of resident species remains elusive. In this study, we used floristic resurvey data from 896 permanent vegetation plots across 62 European mountain summits to show that local extinctions have increased over the past 21 years. Extinction rates rose with the magnitude of warming, and species were more likely to go extinct toward their low-elevation range

Marine heatwaves and undernutrition in low- and middle-income countries.

Marine heatwaves are accelerating under climate change and increasingly threaten the lives and livelihoods of coastal populations, particularly in low- and middle-income countries where many households directly depend on local marine fisheries for protein, micronutrients, and income. To quantify this threat, we link individual-level data on child and maternal health from 9,813 coastal sites in 36 low- or middle-income countries to heatwave exposures in the nearby ocean, and use this linked datas

Pelagic food web realignment supports resilient larvae of Southern Bluefin Tuna in a warming ocean

Many of the oceans’ top predatory fishes at low to mid latitudes face an uncertain future as their vulnerable larvae deal with higher environmental temperature and reduced productivity associated with climate change. However, ocean ecosystem models that predict a general decline of zooplankton prey with warming and stratification hardly ever account for complexities in pelagic food webs that might make them resilient in providing food resources for larvae. We illustrate such complexities in comp
