Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.
All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.
That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

Many ongoing processes in today's landscapes impact our environment considerably. Thus, it is enormously important to gather information on qualitative characteristics of our landscapes in order to effectively counteract the negative developments. Structural functionality as proxy for the assessment of habitat quality and species patterns has already proven potential to successfully describe ecological values.
Cross-cultural perceptions of ecosystem services: A social inquiry on both sides of the Israeli–Jordanian border of the Southern Arava Valley Desert
This research explores local resident perspectives on ecosystem services (ES) in the hyper-arid Arava Valley/Wadi Araba, which spans across both Israel and Jordan. Identifying and characterizing ES, an increasingly popular precursor for crafting sustainable natural resource management and land use policy, is an inherently multi-disciplinary endeavor. Our goal is to apply social research tools, in particular in-depth interviews with local residents, to understand their perspectives concerning ES.
Agricultural management affects the response of soil bacterial community structure and respiration to water-stress
Soil microorganisms are responsible for organic matter decomposition processes that regulate soil carbon storage and mineralisation to CO₂. Climate change is predicted to increase the frequency of drought events, with uncertain consequences for soil microbial communities. In this study we tested the hypothesis that agricultural management used to enhance soil carbon stocks would increase the stability of microbial community structure and activity in response to water-stress.
Impacts of heavy grazing on plant species richness: A comparison across rangeland biomes of South Africa
The net effect of heavy grazing and land degradation on plant diversity and richness is insufficiently understood for incorporation in national biodiversity assessments. A study was undertaken to determine the effects of heavy grazing primarily on richness of vascular plant species across the arid and semi-arid rangeland biomes of South Africa. Major grazing contrasts were systematically identified for sampling in rangelands of Succulent Karoo, Nama-Karoo, Thicket, Grassland, Kalahari dune savanna and Mopane savanna.
Redistributions of ¹³⁷Cs and soil components on cultivated hill slopes with hedgerows as conservation measures
¹³⁷Cs tracing technique combined with soil composition characterization was used to investigate the mechanism and effectiveness of conservation measures for cultivated hill slopes of strongly weathered acidic Acrisol. The results of analysis of 66 soil samples taken across six plots showed much lower losses of ¹³⁷Cs, soil organic carbon (SOC), and nutrients in the four treatments of alley cropping with hedgerows compared to the two control treatments of bare land and without conservation measures.
