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.

Displaying 1436 - 1440 of 1605Current distribution of older and deciduous forests as legacies from historical use patterns in a Swedish boreal landscape (1725-2007)
We combine historical maps and satellite derived data to reconstruct the development of a Swedish boreal landscape over the past 300 years. The aim is to understand legacies from past use patterns in present-day forest composition and consequences for conservation objectives from a landscape perspective. We analyze landscape development in cross-tabulation matrixes, building change trajectories. These trajectories are tested in linear models to explain the distribution of present-day landscape composition of coniferous, mixed, and deciduous forests >110 years.
Integration of albedo effects caused by land use change into the climate balance: Should we still account in greenhouse gas units
Due to impacts of albedo on climate change, benefits of afforestation/reforestation regimes are under debate. In this paper we investigate how to incorporate albedo changes in a carbon accounting tool to show the net effect of land use change on the climate. Using a study area in southern Europe, albedo and carbon sequestration modelling results are linked to determine the combined radiative forcing balance.
Effect of land use and management on soil bacterial biodiversity as measured by PCR-DGGE
Agricultural land use and sugarcane residue management effects on soil bacterial communities at two long-term sites in KwaZulu/Natal, South Africa, were investigated by PCR-DGGE. Land uses at site 1 were maize [M]; pre-harvest burnt sugarcane [SC]; permanent kikuyu pasture [KIK]; pine forest [PF]; wattle forest [W] and undisturbed native grassland [NAT], whereas land managements at site 2 were pre-harvest burning of sugarcane [Bto] or green cane harvesting with retention of a trash mulch [T] (with [F] or without [Fo] fertilizer additions).
GIS-based multi-criteria evaluation to land suitability modelling for giant prawn (Macrobrachium rosenbergii) farming in Companigonj Upazila of Noakhali, Bangladesh
Site selection is a key factor in any aquaculture operation, affecting both success and sustainability as well as solving conflicts between different activities and making rational use of the land. The study was conducted to identify appropriate site for the farming of giant prawn, Macrobrachium rosenbergii, in Companigonj of Noakhali, Bangladesh using GIS-based multi-criteria evaluation taking 20 base layers of water quality, soil characteristics and infrastructure facilities.
Relationship between soil δ¹⁵N, C/N and N losses across land uses in New Zealand
Several of the major processes that result in N loss from soil (nitrification, ammonia volatilization, and denitrification) discriminate against ¹⁵N and fractionate the stable N isotopes, thus δ¹⁵N of ecosystem components has been suggested as an indicator of ecosystem N leakiness. This concept has been applied more successfully to native systems (primarily forest) than to managed systems where N inputs are greater and N cycling processes have potentially been modified.
