The Functional Role Of Biodiversity In Ecosystems: Incorporating Trophic Complexity, J. Emmett Duffy, Bradley J. Cardinale, Kristin E. France, Peter B. Mcintyre, Elisa Thebault, Michel Loreau

VIMS Articles

Understanding how biodiversity affects functioning of ecosystems requires integrating diversity within trophic levels (horizontal diversity) and across trophic levels (vertical diversity, including food chain length and omnivory). We review theoretical and experimental progress toward this goal. Generally, experiments show that biomass and resource use increase similarly with horizontal diversity of either producers or consumers. Among prey, higher diversity often increases resistance to predation, due to increased probability of including inedible species and reduced efficiency of specialist predators confronted with diverse prey. Among predators, changing diversity can cascade to affect plant biomass, but the strength and sign of this effect depend …

Programs of the Department of Agriculture and Food Western Australia apply benefit-cost analysis to assist in the allocation of funds to those areas likely to make the largest contribution to the rural economy and thus to achieve the Department outcome of increased market competitiveness and profitability. To learn lessons from the completed projects the Programs also use ex post analyses. Information collected in the course of the ex post analyses can usefully improve the assessment of proposed projects.

Cottonwood And Antelope Range Livestock Research Stations Unit Report, Kenneth C. Olson

South Dakota Beef Report, 2007

Two research stations, the Cottonwood and Antelope Range Livestock Research Stations, are located in western South Dakota that allow research projects focused on needs of range livestock producers in that region. The stations are comprised primarily of native rangeland that is grazed by cattle at both stations, and also by sheep at Antelope. The philosophy of the research efforts has been focused on conducting applied research to solve problems and address rangeland and livestock management opportunities relevant to the livestock producers and land mangers of the region.

Case Study: Dried Distillers Grains As Creep Feed For Yearling Beef Cattle Grazing Sandhill Range, R. N. Funston, D. C. Adams, M. C. Stockton

West Central Research and Extension Center, North Platte

Seventy-nine crossbred steers and heifers born in June or August were stratified by weight, calving group, and sex and assigned to treatment or control. Yearlings in the treatment group (TRT; n = 40) grazed native summer Sandhill range and had access to ad libitum dried distillers grains (DDG) pellet in a creep feeder for 54 d of a 63-d grazing period. Control (CON; n = 39) yearlings grazed in an adjacent pasture without DDG. Immediately after the grazing period, yearlings were placed in a feedlot and fed to a similar finish end point. Individual forage and DDG intake …

Impact Of More Intensive Grazing On Nitrogen And Phosphorus In Shallow Aquifers Of The Southern Perth Basin, D L. Bennett, Patrick Donnelly, Peter J. Tille

Resource management technical reports

This study reports on the nutrient content, pH and salinity of groundwater samples collected from the watertable and within the Superficial and the upper Leederville Aquifers from the Southern Perth Basin, south of Pinjarra, Western Australia. Sampling was undertaken to determine the impact of intensification of broadscale grazing on groundwater nutrients in the area.

Grazing Impacts Of Diverse Zooplankton Taxa On Thin Layers, Alexander Bochdansky

OES Faculty Publications

The US Navy needs to know how distributions and abundances of light-scattering and sound-scattering organisms in the ocean vary in space and time, particularly in the vertical dimension. Recent field observations have shown that many biological properties may vary substantially over small e.g. centimeter scales, commonly referred to as thin layers e.g. Cowles et al. 1998, 1999, Hanson Donaghay 1998, Holliday et al. 1999, Dekshenieks et al. 2001, Alldredge et al. 2002, Rines et al. 2002. Our previous ONR-funded research has allowed us to begin to understand how zooplankton interact with thin layers and how they can take advantage of …
