Understanding climatic effects on cropland water use efficiency at different elevations is imperative for managing agricultural and production in response to ongoing climate change climate-sensitive areas with complex topography, such as southwestern China. We investigated China each 100-m elevation bin during 2001–2017. The maximum was 1.71 gC kg−1 H2O the 1900–1999 m under growing season temp...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

Interannual variability (IAV) in net ecosystem exchange of carbon (NEE) is a critical factor in projections of future ecosystem changes. However, our understanding of IAV is limited because of the difficulty in isolating its numerous causes. We proposed that IAV in NEE is primarily caused by climatic variability, through its direct effects on photosynthesis and respiration and through its indir...

Given the complementary nature of static and dynamic analysis, there has been much work on identifying means of combining the two. In particular, the use of static analysis as a means of alleviating the overheads induced by dynamic analysis, typically by trying to prove parts of the properties, which would then not need to be verified at runtime. In this paper, we propose a novel framework whic...

Despite broad interest in using payment for ecosystem services to promote changes in the use of natural capital, there are few expost assessments of impacts of payment for ecosystem services programs on ecosystem service provision, program cost, and changes in livelihoods resulting from program participation. In this paper, we evaluate the Paddy Land-to-Dry Land (PLDL) program in Beijing, China...

Secondary salinisation of rivers and streams is a global and growing threat that might be amplified by climate change. It can have many different causes, like irrigation, mining activity or the use of salts as de-icing agents for roads. Freshwater organisms only tolerate certain ranges of water salinity. Therefore secondary salinisation has an impact at the individual, population, community and...

Invasions by alien plants can change the large-scale functioning of native ecosystems and alter the population dynamics and community structure of native species. Such ecosystem-level changes affect the ways local systems interact with surrounding ecosystems, with downstream ecosystems and groundwater, and with the atmosphere. Large-scale changes in ecosystems caused by biological invasions rep...
