Changes in Breeding Bird Populations with Habitat Restoration in Northern Iowa
—Native tallgrass prairie and wetland habitat in the Prairie Pothole Region of the United States have declined over the past two centuries. Bird communities using these habitats have also experienced widespread declines that are often attributed to severe habitat loss and fragmentation. We estimated the change, or turnover, in bird populations in the Eagle Lake Wetland Complex, Iowa, with ongoi...
متن کاملPatch-and landscape-scale effects on area sensitivity of grassland birds in Iowa
The Iowa landscape has been drastically transformed due to agricultural practices, causing population declines in many grassland bird species. Of greatest concern are bird species that are considered to be area sensitive. The Iowa State Preserve System is composed of tracts of prairies, wetlands, and woodlands that can provide habitat for many grassland bird species. This study provides an inve...
متن کاملComparison of Whittaker and Modified-Whittaker plots to estimate species richness in semi-arid grassland and shrubland
Biological diversity and species richness have been declined throughout the world as a result of human activities. Measuring species richness is important in rangeland conservation to evaluate the status and trends of native plant species, detecting non-native species invasion and monitoring rare species. However, heterogeneity in plant distribution makes inventories difficult. In this study tw...
متن کاملResponses of Soil Seed Bank and Vegetation to the Increasing Intensity of Human Disturbance in a Semi-Arid Region of Northern China
To provide more insights into the responses of the soil seed bank and vegetation to human disturbance intensity, we selected four land use types, including: native grassland (no human disturbance), abandoned artificial grassland (light human disturbance), artificial grassland (moderate human disturbance), and farmland (severe human disturbance) in a semi-arid climate of northern China. The spec...
متن کاملLocal hydrologic effects of introducing non-native vegetation in a tropical catchment
This study investigates the hydrologic implications of land use conversion from native vegetation to rubber (Hevea brasiliensis) in Southeast Asia. The experimental catchment, Nam Ken (69 km2), is located in Xishuangbanna Prefecture (22°N, 101 °E), in the south of Yunnan province, in southwestern China. During 2005 and 2006, we collected hourly records of 2 m deep soil moisture profiles in rubb...
