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.

Piñon (Pinus spp.) and juniper (Juniperus spp.) expansion and infilling in sagebrush (Artemisia L.) steppe communities can lead to high-severity fire and annual weed dominance. To determine vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding, we measured cover for shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah.
Urbanites, smallholders, and the quest for empathy: Prospects for collaborative planning in the periurban Shullcas Valley, Peru
Given the regional geographic specificities of Central Andean valleys, the social and environmental impact of dispersed urbanization on smallholder farmers is particularly high in the new urban peripheries of Peruvian mountain cities.
Assessment of measured and perceived microclimates within a tropical urban forest
Urban greenery is a favoured approach applied towards reducing urban warmth and climate discomfort, but ascertaining its measured and perceived effectiveness in tropical climates is relatively understudied. To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data.
Labor out-migration and agricultural change in rural China: A systematic review and meta-analysis
The relationships between migration and agriculture represent a key aspect of rural restructuring in China and many other developing countries. Previous research largely generated mixed and incomplete findings on the effects of rural out-migration on agricultural change. Meta-analysis is considered as an important research strategy for comparing and integrating results from individual studies. Using a qualitative comparative analysis (QCA) approach, we conducted a systematic review and meta-analysis of recent case studies of labor out-migration and agricultural change in rural China.
Can ecological land classification increase the utility of vegetation monitoring data?
Vegetation dynamics in rangelands and other ecosystems are known to be mediated by topoedaphic properties. Vegetation monitoring programs, however, often do not consider the impact of soils and other sources of landscape heterogeneity on the temporal patterns observed. Ecological sites (ES) comprise a land classification system based on soil, topographic, and climate variations that can be readily applied by land managers to classify topoedaphic properties at monitoring locations.
