Purpose of wetland creation and restoration and expected results (protection vs. nourishment) Riparian ecosystems generally compose a minor proportion of surrounding areas, but typically are more structurally diverse and more productive in plant and animal biomass than adjacent upland areas. Riparian areas supply food, cover, and water (especially important in the arid regions) for a large dive...
The global trade in wildlife provides disease transmission mechanisms that not only cause human disease outbreaks but also threaten livestock, international trade, rural livelihoods, native wildlife populations, and the health of ecosystems. Outbreaks resulting from wildlife trade have caused hundreds of billions of dollars of economic damage globally. Rather than attempting to eradicate pathog...
The British Columbia Ministry of Forests is developing a practical classification system for British Columbia’s wetland and riparian ecosystems. The project has identified a diversity of wetland and riparian ecosystem types, in terms of environmental profiles, regional distribution, and habitat values. Urbanization, agricultural development, hydrological modification, livestock grazing, intensi...
Information about the distribution of grass nitrogen (N) concentration is crucial in understanding rangeland vitality and facilitates effective management of wildlife and livestock. A challenge in estimating grass N concentration using remote sensing in savannah ecosystems is that these areas are characterised by heterogeneity in edaphic, topographic and climatic factors. The objective is to te...
We estimate the annual financial losses resulting from wildlife damage to major crops and livestock in Nebraska. For each wildlife species, the damage problem is presented along with a description of how the estimate was made. Field crop estimates include losses from Plains pocket gophers (Geomys bursarius), commensal rodents (Rattus norvegicus and Mus musculus), field rodents in grain fields (...
Veterinary research and clinical contributions reach into every aspect of biomedical health and science: livestock production and food safety; zoonotic diseases, epidemiology, and public health; comparative basic and translational research; companion animal medicine and surgery; animal welfare and the human-animal bond; and wildlife and ecosystem health. Diversity is not only a key strength of ...
