生态承载力与生态系统生产总值耦合的生态系统服务评估—以福建省长汀县为例
Shuitu Baochi Xuebao, 2021 生态系统质量是区域探索生态优先、绿色发展为导向的高质量发展的重要基础。开展区域生态系统服务评估可获取国土空间生态本底特征，为生态系统保护格局构建提供现状底图，明确生态系统修复重点、国土空间优化提供导向。以长汀县为例，基于地区生态典型性、区域生物量差异及公众支付意愿与能力构建特色评价指标，采用生态承载力与生态系统生产总值耦合研究方法，对长汀县生态系统服务进行县域、镇域、村域及系统斑块等多尺度评估。结果表明：长汀县生态系统服务等级空间分布符合区划规律，大致呈中间低、四周高的特征；尺度细化使结果分布异质性更强，

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

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 ...
