1. Despite commonly used to unveil the complex structure of interactions within ecological communities and their value to assess their resilience against external disturbances, network analyses have seldom been applied in plant communities....
Cereal progenitors differ in stand harvest characteristics from related wild grasses [0.03%]
谷物祖先与相关的野生草在群体收获特征上有所不同

Catherine Preece et al.
The domestication of crops in the Fertile Crescent began approximately 10,000 years ago indicating a change from a hunter-gatherer lifestyle to a sedentary, agriculture-based existence. The exploitation of wild plants changed during this tr...
Land use in mountain grasslands alters drought response and recovery of carbon allocation and plant-microbial interactions [0.03%]
土地利用改变高山草land干旱应对和碳分配及植物-微生物相互作用的恢复
Stefan Karlowsky,Angela Augusti,Johannes Ingrisch et al.
Stefan Karlowsky et al.
Mountain grasslands have recently been exposed to substantial changes in land use and climate and in the near future will likely face an increased frequency of extreme droughts. To date, how the drought responses of carbon (C) allocation, a...
Scale dependence of the diversity-stability relationship in a temperate grassland [0.03%]
温带草地多样性-稳定性的尺度依赖性关系
Yunhai Zhang,Nianpeng He,Michel Loreau et al.
Yunhai Zhang et al.
A positive relationship between biodiversity and ecosystem stability has been reported in many ecosystems; however, it has yet to be determined whether and how spatial scale affects this relationship. Here, for the first time, we assessed t...
Expansion of deciduous tall shrubs but not evergreen dwarf shrubs inhibited by reindeer in Scandes mountain range [0.03%]
驯鹿通过抑制落叶灌木而非常绿灌木扩张来减缓北方水分限制环境下的植被变化速率
Tage Vowles,Bengt Gunnarsson,Ulf Molau et al.
Tage Vowles et al.
One of the most palpable effects of warming in Arctic ecosystems is shrub expansion above the tree line. However, previous studies have found that reindeer can influence plant community responses to warming and inhibit shrubification of the...

1. The environmental filtering hypothesis predicts that the abiotic environment selects species with similar trait values within communities. Testing this hypothesis along multiple - and interacting - gradients of climate and soil variables...
Drought history affects grassland plant and microbial carbon turnover during and after a subsequent drought event [0.03%]
干旱历史影响后续干旱事件期间和之后草地植物和微生物的碳周转
Lucia Fuchslueger,Michael Bahn,Roland Hasibeder et al.
Lucia Fuchslueger et al.
Drought periods are projected to become more severe and more frequent in many European regions. While effects of single strong droughts on plant and microbial carbon (C) dynamics have been studied in some detail, impacts of recurrent drough...
Consistent, small effects of treefall disturbances on the composition and diversity of four Amazonian forests [0.03%]
亚马逊四个森林中树木倾倒干扰对群落组成和多样性的小规模但一致的影响
Timothy R Baker,Dilys M Vela Díaz,Victor Chama Moscoso et al.
Timothy R Baker et al.
Understanding the resilience of moist tropical forests to treefall disturbance events is important for understanding the mechanisms that underlie species coexistence and for predicting the future composition of these ecosystems. Here, we te...
Transients drive the demographic dynamics of plant populations in variable environments [0.03%]
生境波动中植物种群的瞬变驱动了其数量动态变化规律
Jenni L McDonald,Iain Stott,Stuart Townley et al.
Jenni L McDonald et al.
The dynamics of structured plant populations in variable environments can be decomposed into the 'asymptotic' growth contributed by vital rates, and 'transient' growth caused by deviation from stable stage structure.We apply this framework ...
Rehabilitating the cyanobacteria - niche partitioning, resource use efficiency and phytoplankton community structure during diazotrophic cyanobacterial blooms [0.03%]
固氮蓝藻水华期间的生态位分化、资源利用效率及浮游植物群落结构研究

Blooms of nitrogen-fixing cyanobacteria are recurrent phenomena in marine and freshwater habitats, and their supplying role in aquatic biogeochemical cycles is generally considered vital. The objective of this study was to analyse whether a...
