Effects of an Experimental Water-level Drawdown on Methane Emissions from a Eutrophic Reservoir [0.03%]
水库水位降低对甲烷排放的影响——以富营养化水库为例
Jake J Beaulieu,David A Balz,M Keith Birchfield et al.
Jake J Beaulieu et al.
Reservoirs are a globally significant source of methane (CH4) to the atmosphere. However, emission rate estimates may be biased low due to inadequate monitoring during brief periods of elevated emission rates (that is, hot moments). Here we...
Aboveground Carbon Storage and Its Links to Stand Structure, Tree Diversity and Floristic Composition in South-Eastern Tanzania [0.03%]
坦桑尼亚东南部森林的地上碳储量及其与林分结构、树种多样性及植被组成的关系

Iain M McNicol et al.
African savannas and dry forests represent a large, but poorly quantified store of biomass carbon and biodiversity. Improving this information is hindered by a lack of recent forest inventories, which are necessary for calibrating earth obs...
Vertical Redistribution of Soil Organic Carbon Pools After Twenty Years of Nitrogen Addition in Two Temperate Coniferous Forests [0.03%]
温带针叶林土壤有机碳库垂直再分配对施氮的响应
Stefan J Forstner,Viktoria Wechselberger,Stefanie Müller et al.
Stefan J Forstner et al.
Nitrogen (N) inputs from atmospheric deposition can increase soil organic carbon (SOC) storage in temperate and boreal forests, thereby mitigating the adverse effects of anthropogenic CO2 emissions on global climate. However, direct evidenc...
Greenhouse Gas Emissions from Freshwater Reservoirs: What Does the Atmosphere See? [0.03%]
水库的温室气体排放：大气看到了什么？
Yves T Prairie,Jukka Alm,Jake Beaulieu et al.
Yves T Prairie et al.
Freshwater reservoirs are a known source of greenhouse gas (GHG) to the atmosphere, but their quantitative significance is still only loosely con- strained. Although part of this uncertainty can be attributed to the difficulties in measurin...
Watershed Land Use and Seasonal Variation Constrain the Influence of Riparian Canopy Cover on Stream Ecosystem Metabolism [0.03%]
流域土地利用和季节变化制约河岸林冠覆盖对溪流生态系统代谢的影响

Ecosystem metabolism is an important determinant of trophic structure, nutrient cycling, and other critical ecosystem processes in streams. Whereas watershed- and local-scale controls on stream metabolism have been independently investigate...
Land Use Alters the Drought Responses of Productivity and CO2 Fluxes in Mountain Grassland [0.03%]
土地利用改变高山草甸生产力和二氧化碳通量对干旱的响应
Johannes Ingrisch,Stefan Karlowsky,Alba Anadon-Rosell et al.
Johannes Ingrisch et al.
Climate extremes and land-use changes can have major impacts on the carbon cycle of ecosystems. Their combined effects have rarely been tested. We studied whether and how the abandonment of traditionally managed mountain grassland changes t...
Mineral-Associated Soil Carbon is Resistant to Drought but Sensitive to Legumes and Microbial Biomass in an Australian Grassland [0.03%]
澳大利亚草地土壤固相碳组分对气候变化驱动因子的脆弱性不同
Alberto Canarini,Pierre Mariotte,Lachlan Ingram et al.
Alberto Canarini et al.
Drought is predicted to increase in many areas of the world with consequences for soil carbon (C) dynamics. Plant litter, root exudates and microbial biomass can be used as C substrates to form organo-mineral complexes. Drought effects on p...
To Model or not to Model, That is no Longer the Question for Ecologists [0.03%]
建模还是不建模，这已不再是生态学家需要回答的问题了
Rupert Seidl
Rupert Seidl
Here, I argue that we should abandon the division between "field ecologists" and "modelers," and embrace modeling and empirical research as two powerful and often complementary approaches in the toolbox of 21st century ecologists, to be dep...
On the importance of shrub encroachment by sprouters, climate, species richness and anthropic factors for ecosystem multifunctionality in semi-arid Mediterranean ecosystems [0.03%]
半干旱地中海生态系统中灌木入侵、气候、物种丰富度和人为因素对生态系统多功能性的重要性研究
José L Quero,Fernando T Maestre,Victoria Ochoa et al.
José L Quero et al.
One of the most important changes taking place in drylands worldwide is the increase of the cover and dominance of shrubs in areas formerly devoid of them (shrub encroachment). A large body of research has evaluated the causes and consequen...
Effects of Erosion from Mounds of Different Termite Genera on Distinct Functional Grassland Types in an African Savannah [0.03%]
不同白蚁属的土丘侵蚀对非洲稀树草原不同类型功能草场的影响
Cleo M Gosling,Joris P G M Cromsigt,Nokukhanya Mpanza et al.
Cleo M Gosling et al.
A key aspect of savannah vegetation heterogeneity is mosaics formed by two functional grassland types, bunch grasslands, and grazing lawns. We investigated the role of termites, important ecosystem engineers, in creating high-nutrient patch...
