Nesting Ecology of Grassland Birds in an Agricultural Landscape
Agriculture is an appropriate landscape context for grassland reserves. I found agricultural edges do not influence nest predation, reserves in agricultural settings support successful nesting throughout breeding seasons, and cropland is an important foraging habitat for birds provisioning …

Interactions between a changing agricultural landscape and regional trade
… past few decades, international trade including agricultural commodities has grown substantially both in physical volume and in value. International trade of agricultural products masks the true distribution of agricultural land services by importing and exporting agricultural goods through …

Successive Land Surveys as Indicators of Vegetation Change in an Agricultural Landscape
… of 304 land surveys were collected for a small agricultural watershed from early settlement in 1787 through to the present day. Witness corners recorded tree species, shrubs, stumps, snags and non vegetative markers. Types of witness corners were tallied and tested for shifts in frequency across …

Landscape-scale mechanisms of biological pest control in a South Korean agricultural landscape
… of how to manage this service in real-world landscapes is limited by our lack of knowledge of the factors determining landscape-scale pest control, enemy diversity and the relationship between the two. In order to clarify how biological control is provided at large spatial scales, and how it …

The Influence of Switchgrass Establishment on Soil Organic Matter Pools in an Agricultural Landscape
Agricultural activities have significant impacts on global biogeochemical cycles, particularly carbon and nitrogen. Conventional row-crop agriculture accelerates the decomposition of soil organic matter, contributing to atmospheric carbon and declining soil fertility. Planting perennial warm season …

Factors Affecting Songbird Richness, Abundance, and Nest Survival in Riparian Forests in a Midwestern Agricultural Landscape
… important breeding habitat for songbirds in an agriculturally dominated landscape. Research has suggested that songbirds are influenced by habitat at multiple scales (i.e., habitat fragmentation, edge effects, exotic species), therefore it is necessary to know which variables are most important …
