We used bioproxies from paleosoils buried within two aeolian dunes to test hypotheses concerning the origin of dry sandy boreal forests in Canada. These forests are dominated today by Pinus banksiana Lamb. One hypothesis is that too frequen...
Seasonal disconnect between streamflow and retention shapes riverine nitrogen export in the Willamette River Basin, Oregon [0.03%]
俄勒冈威拉米特河流域径流与滞留的季节脱钩塑造了河流氮输出
Jana E Compton,Kara E Goodwin,Daniel J Sobota et al.
Jana E Compton et al.
Watershed nutrient balance studies traditionally focus on annual fluxes. In areas with strongly seasonal, Mediterranean-type climate regimes, riverine nutrient export may be greater during wet seasons when hydrologic forcing overwhelms or b...
Consumer Aggregations Drive Nutrient Dynamics and Ecosystem Metabolism in Nutrient-Limited Systems [0.03%]
消费者聚集驱动营养限制系统内的营养动力学和生态系统代谢率

Carla L Atkinson et al.
Differences in animal distributions and metabolic demands can influence energy and nutrient flow in an ecosystem. Through taxa-specific nutrient consumption, storage, and remineralization, animals may influence energy and nutrient pathways ...
Tracking the dynamic ecological history of a tropical urban estuary as it responds to human pressures [0.03%]
追踪热带城市河口生态系统对人类压力的动态生态响应历史
A Oczkowski,E Santos,A Gray et al.
A Oczkowski et al.
Coastal cities in tropical areas are often low-lying and vulnerable to the effects of flooding and storms. San Juan, Puerto Rico is a good example of this. It is built around a lagoon-channel complex called the San Juan Bay Estuary (SJBE). ...
Slowed Biogeochemical Cycling in Sub-arctic Birch Forest Linked to Reduced Mycorrhizal Growth and Community Change after a Defoliation Event [0.03%]
叶虫害事件后 sub-arctic 白桦林内生菌根生长及群落变化减少导致生物地球化学循环减缓

Thomas C Parker et al.
Sub-arctic birch forests (Betula pubescens Ehrh. ssp. czerepanovii) periodically suffer large-scale defoliation events caused by the caterpillars of the geometrid moths Epirrita autumnata and Operophtera brumata. Despite their obvious influ...

This article categorizes four kinds of adverse effects to human health caused by ecosystem change: direct, mediated, modulated, and systems failure. The effects are categorized on their scale, complexity, and lag-time. Some but not all of t...
Quantitative Analysis of Pedogenic Thresholds and Domains in Volcanic Soils [0.03%]
火山土壤发生学阈值和领域的定量分析

Pedogenic thresholds describe where soil properties or processes change in an abrupt/nonlinear fashion in response to small changes in environmental forcing. Contrastingly, soil process domains refer to the space between thresholds where so...
Influence of Land-Use Intensification on Vegetation C-Stocks in an Alpine Valley from 1865 to 2003 [0.03%]
土地集约利用对高山山谷植被碳库的影响（1865－2003年）
Maria Niedertscheider,Erich Tasser,Monika Patek et al.
Maria Niedertscheider et al.
The role of ecosystems as carbon (C) sinks or sources is intrinsically related to land-use intensity, which determines the land required for biomass production. Here, we systematically investigate the role of different land-use types includ...
Slow Recovery from Local Disturbances as an Indicator for Loss of Ecosystem Resilience [0.03%]
局部干扰后恢复缓慢作为生态系统弹性的丧失指标

Ingrid A van de Leemput et al.
A range of indicators have been proposed for identifying the elevated risk of critical transitions in ecosystems. Most indicators are based on the idea that critical slowing down can be inferred from changes in statistical properties of nat...
Long-Term Simulated Atmospheric Nitrogen Deposition Alters Leaf and Fine Root Decomposition [0.03%]
长期模拟大气氮沉降改变叶和细根分解率

Atmospheric nitrogen deposition increases forest carbon sequestration across broad parts of the Northern Hemisphere. Slower organic matter decomposition and greater soil carbon accumulation could contribute to this increase in carbon seques...
