© The Ecological Society of America www.frontiersinecology.org F many scientists, the only dust they think about is the thin film of material that accumulates on their computer monitor on a regular basis. However, dust has enormous relevance to a wide range of ecological processes and environmental management challenges. Dust is fine particulate material that is removed from the land surface by...

Despite the looming land scarcity suited for agricultural expansion, farmland abandonment is widespread globally. The recultivation of some abandoned farmlands could unlock untapped potential. Yet, little known about determinants recultivation. To better understand behavioral intentions farmers regarding lands, we concentrated on Buryat Republic in Russia, where and with different ethnicities c...

Agricultural land abandonment and its impacts on landscape features have been a striking characteristic of many European rural areas over the last decades. Although previous research identified drivers environmental abandonment, few described post-agricultural trajectories. However, examining driving forces leading to different trajectories is key understand how alternative uses these lands can...

In most habitats in temperate zones, Carabidae show clear intra-annual changes abundance and species composition. the spring, we studied beetle fauna 5 different biotopes differing degree of overgrowth birch forest over a period three years. According to years research, 10,528 specimens (64 from 6 subfamilies) were collected. Twelve beetles found all biotopes. The highest numbers obtained 12-15...

this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

Growing biomass feedstocks from marginal lands is becoming an increasingly attractive choice for producing biofuel as an alternative energy to fossil fuels. Here, we used a biogeochemical model at ecosystem scale to estimate crop productivity and greenhouse gas (GHG) emissions from bioenergy crops grown on marginal lands in the United States. Two broadly tested cellulosic crops, switchgrass, an...

The Deckers Creek watershed in northern West Virginia (USA), containing a land area of 166 km2 (63 mi2), has a long history of industrial development and attendant environmental abuses from both land and water pollution practices. The water in Deckers Creek was sampled in 1974 at 29 locations along the main stem and resampled in 1999-2000 to determine water quality changes over this 25-year per...

Understanding effects of land-use changes driven by the implementation of the "Grain for Green" project and the corresponding changes in soil organic carbon (SOC) storage is important in evaluating the environmental benefits of this ecological restoration project. The goals of this study were to quantify the current soil organic carbon density (SOCD) in different land-use types [cultivated land...
