凋落物分解是土壤养分转移的关键过程,对生态系统碳循环有重要影响。近几十年来由于全球变化加剧,凋落物分解速率(k)可能会发生显著变化,从而对陆地生态系统的功能产生深远的影响。虽然当前关于全球变化对凋落物分解影响的研究已经不少,但在全球尺度上凋落物分解对单一和联合变化因子的响应及其控制因素仍不清晰,相关研究亟待开展。
What limits the ability of plants to draw water from dry soil? That's the question California State University, Fullerton plant biologist H. Jochen Schenk and his collaborators addressed in a study su...
Through utilizing water flow monitoring, rock scratching, soil wood piles and radionuclide 137Cs tracing in the Longhe karst ecological experimental site (hereinafter referred to“Longhe site”), Pinggu...
To understand the mechanisms affecting water balance partitioning during fallow on drylands could improve the fallow management practices in arable land ecosystems. A three-year field experiment was c...
Understanding stable isotope fractionation in trophic networks is important for the interpretation of stable isotope composition of ecosystem components. This work explores the influence of grazing pr...
We present research aimed at determining the role of soil structure in the organization of microbial communities in soil. We have focused on the microbial communities involved in functional roles with...
Sustainability is one of the biggest goals of humankind in the new millennium. An increasing global demand on agricultural products stimulates agricultural expansion in Brazil, especially in the South...
Soil and herbivore gut environments present different challenges to plant degrading bacteria in terms of nutrient availability, fluctuations in moisture, pH and temperature, and temporal constraints, ...
Invasive species have become an increasing threat to many habitats worldwide. This research addressed the questions of whether several invasive woody plants can germinate, survive and grow in light le...
When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a min...
This work was carried out at Sakha Agriculture Research Station, Kafr El-Sheikh, Egypt during the 2010 and 2011 cotton growing seasons to evaluate the effectiveness of imidacloprid and thiamethoxam,...
The morphology and infraciliature of 4 haptorid ciliates obtained from alkaline soil habitats in Van, Turkey, were investigated: Pseudoholophrya terricola Berger, Foissner & Adam, 1984, Paraenchelys w...
Common bean (Phaseolus vulgaris L.) cultivars (cvs) (Göynük 98, Karacaşehir 90, Şehirali 90, ES 855, and Yunus 90) were subjected to drought stress in order to assess the levels of dro...
