Highlights•Source activity (photosynthesis) depends on sink activity (tissue growth).•
Environmental stress constrains sink activity before it affects source activity.•Under drought …

This paper examines the impact of food and energy production on the global N cycle by
contrasting N flows in the late-19th century with those of the late-20th century. We have a …

摘要20 世纪以来, 生物科学的发展异军突起, 成为发展最快的学科, 不仅学科分类逐渐细化,
而且研究领域也逐渐深入, 然而, 这种分化和深入也可能会掩盖生物的一些最普遍特征 …

Terrestrial ecosystem carbon (C) sequestration plays an important role in ameliorating
global climate change. While tropical forests exert a disproportionately large influence on …

Ecosystems worldwide are receiving increasing amounts of reactive nitrogen (N) via
anthropogenic activities with the added N having potentially important impacts on …

This paper contrasts the natural and anthropogenic controls on the conversion of unreactive
N 2 to more reactive forms of nitrogen (Nr). A variety of data sets are used to construct global …

Fundamentals of Soil Ecology, 3rd Edition, offers a holistic approach to soil biology and
ecosystem function, providing students and ecosystem researchers with a greater …

Inspired by previous studies that have indicated consistent or even well-constrained
(relatively low variability) relations among carbon (C), nitrogen (N) and phosphorus (P) in …

Our meta‐analysis of 126 nitrogen addition experiments evaluated nitrogen (N) limitation of
net primary production (NPP) in terrestrial ecosystems. We tested the hypothesis that N …

This book describes the underlying water conditions and geologies that support viable
riparia, illustrates the ecological characteristics of riparia, and discusses how riparia are …
