Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

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 ...

The coordination of dehydration tolerance and avoidance in oaks is mediated by leaf habit across a precipitation gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests worldwide are increasingly impacted by drought due to climate change, prompting plants to adapt through dehydration tolerance (DT) and avoidance (DA), two distinct physiological strategies.

Land-use Effect and Seasonal Hydrologic Controls on Nitrogen Export in Typical Sub-watersheds within Jiulong River Watershed [PDF]

, 2016
在过去的几十年里，世界范围的大部分地区都经历了由于进入近海的河流氮通量的大量增加而导致的富营养化和其它生态损害。氮、磷作为限制性营养盐，控制着河流－近海系统富营养化，威胁着我们所依赖的生态系统服务与功能。河流营养盐状况是植被、土壤、地形、气候、土地利用状况等自然和人为因素综合作用的结果，这些因素在不同时空尺度内交互作用，使得河流营养盐输出的影响机制研究更具挑战性。本研究开展亚热带流域氮输出对土地利用及水文状况季节性变动的响应，可为流域综合管理和区域用水安全提供科技支撑。 本研究通过现场监测、GIS技术 ...

Mycorrhiza‐induced alterations in the spatial structure of stands in a subtropical forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Spatial aggregation patterns represent snapshots of ecological processes that occurred over an extensive period. Such processes can shape both the conspecific and the heterospecific spatial structure of plants across woody habitats.

黄灌沙区农田耕层土壤性状空间异质性分析

Shuitu Baochi Xuebao, 2005
用地统计学的方法,研究了黄灌沙区农田耕作层(030 cm)土壤的有机质、全氮、碱解氮、速效磷、速效钾、pH和电导率的空间变异规律。结果表明,农田耕作层土壤养分的空间异质性主要由随机性因子如土壤耕作措施,包括施肥、灌溉和作物轮作等造成,这与该区农田耕作层土壤是引黄灌溉改良的结果有关。土壤养分含量的变异函数均可很好地拟合成线性模型,块金值和基台值之比(C0/C0 C)均为1,说明随机性因子是导致该区土壤性状空间变异的主要因素,在整个尺度上具有恒定的变异,造成了土壤性状的相对均一。pH的变异函数为指数模型 ...

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species

Conservation Biology, EarlyView.
Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

Conservation Biology, EarlyView.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
