Climate change alters forest development pathways, with consequences for ecosystem services and biodiversity. As the rate of warming increases, ecosystem change is expected to accelerate. However, ecosystem dynamics can have many causes unr...

Legacies of past climate conditions and historical management govern forest productivity and tree growth. Understanding how these processes interact and the timescales over which they influence tree growth is critical to assess forest vulne...

Streams and rivers form dense networks that drain the terrestrial landscape and are relevant for biodiversity dynamics, ecosystem functioning, and transport and transformation of carbon. Yet, resolving in both space and time gross primary p...
Animal-Mediated Ecosystem Process Rates in Forests and Grasslands are Affected by Climatic Conditions and Land-Use Intensity [0.03%]
气候条件和土地利用强度影响森林和草原中的以动物介导的生态系统过程速率

Decomposition, vegetation regeneration, and biological control are essential ecosystem functions, and animals are involved in the underlying processes, such as dung removal, seed removal, herbivory, and predation. Despite evidence for decli...
Governance in the Face of Extreme Events: Lessons from Evolutionary Processes for Structuring Interventions, and the Need to Go Beyond [0.03%]
极端事件下的治理：进化过程对干预措施结构的启示及超越必要性

Simon A Levin et al.
The increasing frequency of extreme events, exogenous and endogenous, poses challenges for our societies. The current pandemic is a case in point; but "once-in-a-century" weather events are also becoming more common, leading to erosion, wil...
Evaluating Drought Impact on Postfire Recovery of Chaparral Across Southern California [0.03%]
评估干旱对南加州沙布拉雷植被火灾后恢复的影响

Emanuel A Storey et al.
Chaparral shrubs in southern California may be vulnerable to frequent fire and severe drought. Drought may diminish postfire recovery or worsen impact of short-interval fires. Field-based studies have not shown the extent and magnitude of d...
Long-Term Responses of Mediterranean Mountain Forests to Climate Change, Fire and Human Activities in the Northern Apennines (Italy) [0.03%]
意大利北部亚平宁山脉地中海山区森林对气候变化、火灾和人类活动的长期响应

César Morales-Molino et al.
Fagus sylvatica (beech) dominates the montane forests of the Apennines and builds old-growth high-conservation value stands. However, recent severe drought-induced diebacks raise concern on the future persistence of these forests and of Sou...
Recent Growth and Expansion of Birch Shrubs Across a Low Arctic Landscape in Continental Canada: Are These Responses More a Consequence of the Severely Declining Caribou Herd than of Climate Warming? [0.03%]
加拿大内陆低纬度北极景观中白桦灌木的近期增长和扩张：这些变化是严重减少的驯鹿种群带来的，而非气候变暖所致？

The recent widespread expansion of deciduous shrubs across much of the Arctic has been largely attributed to climate warming. This study investigated decadal growth rates of dwarf birch (Betula glandulosa) across a low Arctic landscape in t...
Cell Size Decrease and Altered Size Structure of Phytoplankton Constrain Ecosystem Functioning in the Middle Danube River Over Multiple Decades [0.03%]
中等大小的多瑙河生态系统功能在多个十年里由于浮游植物细胞尺寸减小和尺寸结构变化而受到限制
