Current global change substantially threatens pollinators, which directly impacts the pollination services underpinning stability, structure and functioning of ecosystems. Amongst these threats, many synergistic drivers, such as habitat destruction fragmentation, increasing use agrochemicals, decreasing resource diversity, well climate change, are known to affect wild managed bees. Therefore, r...
This study was carried out to compare the biodiversity parameters of epigean insect species in 3 different regions with geographical conditions. Tefenni Plain, Beyköy (Abdülmelik) Plain and Çaylı Mountain Village, which are located at altitudes, were chosen as area. Pitfall traps placed agro-ecosystems anise fennel each region caught pitfall checked weekly. A total 2086 individuals belonging 11...
Domestication took plants from natural environments to agro-ecosystems, where resources are generally plentiful and plant life is better buffered against environmental risks such as drought or pathogens. We hypothesized that predictions derived from the comparison of low vs high resource ecosystems (faster-growing plants promoting faster nutrient cycling in the latter) extrapolate to the proces...
Abstract The article outlines the location, scales, and intensity of current ecosystems transformation due to operation agro-industrial complex industries in Bryansk Oblast Russian Federation. By means official statistic data space images gathered from open sources, key factors determining environmental condition agricultural landscapes are identified. For each landscape’s units, a detailed des...
Preface This document reports on a decision support system that has been developed by a research project carried out by Montana State University (MSU), Wageningen University (WU), and the International Potato Center (CIP), in cooperation with several national research institutes and universities in Peru and Ecuador. Three donors supported the project. The International Service to National Agric...
The future health of ecosystems is arguably as dependent on urban sprawl as it is on human-caused climatic warming. Urban sprawl strongly impacts the urban ecosystems it creates and the natural and agro-ecosystems that it displaces and fragments. Here, we project urban sprawl changes for the next 50 years for the fast-growing Southeast U.S. Previous studies have focused on modeling population d...
Pest insects pose a significant threat to food production worldwide resulting in annual losses worth hundreds of billions of dollars. Pest control attempts to prevent pest outbreaks that could otherwise destroy a sward. It is good practice in integrated pest management to recommend control actions (usually pesticides application) only when the pest density exceeds a certain threshold. Accurate ...
At the moment we realize that the world will face major changes in land use in the coming decades. Agricultural production will need to meet the needs of the world population which is expected to double to 12 billion, and to meet the increasing demand as a result of continued economic growth and consumer demands. Agriculture needs to meet this rising demand on less land, with less resources suc...
