Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

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.

Kongjian kexue xuebao, 2023 为研究长期禁食过程中大鼠尿酸代谢的变化及其潜在的调控机制，以Sprague-Dawley（SD）大鼠为动物模型，通过病理组织切片、生化检测、荧光定量PCR（qRT-PCR）以及蛋白免疫印迹（Western blotting）等方法分析不同禁食时间（1，2，3，5，7天）大鼠尿酸水平及其代谢相关基因和蛋白的表达变化。结果表明，长期禁食未对大鼠肾脏组织产生明显的损伤，引起了血尿酸水平上升、尿尿酸水平波动性变化和血液尿酸酶活性升高；随着禁食时间的延长，主要尿酸转运蛋白的mRNA和蛋白表达水平逐渐上调 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.
