Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

He jishu近年来，全球对核电站可持续性和灵活性的需求日益增加，微型反应堆具备体积小、灵活性高、安全性高、适应性强、维护需求低等不可替代的优势，能够为大型电网无法覆盖的地区供电，因而成为核能方向的研究热点。SiC基车载式气冷微堆（SiC-based Vehicular Micro Reactor，SVMR）专为偏远地区提供电力服务，其堆芯设计紧凑，具有燃料装载能力强及高燃耗深度的优势。然而，由于反射层具有较强的中子慢化能力，大量中子经慢化后返回活性区边缘，致使该区域中子通量升高，功率密度显著增大 ...

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.

Journal of Analytical Psychology, EarlyView.Abstract This paper explores what is happening, for a trainee, when an ethical boundary violation occurs by the analyst with a fellow peer in training. I am approaching this through the Jungian concept of the alchemical vas as I attempt to make meaning of a catastrophic collapse of the analytic work.

Housing policies and market returns in China: Evidence from a novel policy index
Real Estate Economics, EarlyView.Abstract This article examines the relationship between housing policy interventions and market returns in China with a novel policy index. Using natural language processing techniques, we construct a sentence‐level policy index based on government policy documents from 2008 to 2024.

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
