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.

Although spatial scale is important for understanding ecological processes and guiding conservation planning, studies combining a range of scales are rare. Habitat suitability modelling has been used traditionally to study broad-scale patterns of species distribution but can also be applied to address conservation needs at finer scales. We studied the ability of presence-only species distribution modelling to predict patterns of habitat selection at broad and fine spatial scales for one of the rarest mammals in the UK, the grey long-eared bat (Plecotus austriacus).
agent based model to simulate structural and land use changes in agricultural systems of the argentine pampas
The Argentine Pampas, one of the main agricultural areas in the world, recently has undergone significant changes in land use and structural characteristics of agricultural production systems. Concerns about the environmental and societal impacts of the changes motivated development of an agent-based model (ABM) to gain insight on processes underlying recent observed patterns. The model is described following a standard protocol (ODD).
Differential influence of land use/cover change on topsoil carbon and microbial activity in low-latitude temperate forests
Land use/cover change (LUCC) is one of the main factors that control the terrestrial carbon (C) cycle. We examined the effect of LUCC on topsoil C, microbial biomass C (MBC) and microbes mediated processes related to C circulation and their relationship with other soil properties in low-latitude mountain temperate forests. We selected three sites in the northwest of Cofre de Perote volcano (Mexico) in an altitudinal gradient (piedmont, lower mountain slope and mid slope).
Five years of carbon dioxide fluxes measurements in a highly vegetated suburban area
Suburban areas continue to grow rapidly and are potentially an important land-use category for anthropogenic carbon-dioxide (CO₂) emissions. Here eddy covariance techniques are used to obtain ecosystem-scale measurements of CO₂ fluxes (FC) from a suburban area of Baltimore, Maryland, USA (2002–2006). These are among the first multi-year measurements of FC in a suburban area. The study area is characterized by low population density (1500inhabitants km⁻²) and abundant vegetation (67.4% vegetation land-cover).
Review of Quantitative Tools for Assessing the Diffuse Pollution Response to Farmer Adaptations and Mitigation Methods Under Climate Change
In an era of global climate change, the agricultural sector faces the challenge of increasing the production of safe and nutritious food supplies to meet a growing world population while safeguarding the environment. Farmers will adapt their agricultural practices to a changing climate to safeguard against loss of production and to take advantage of any positive climatic conditions.
