Management Of The Houtman Abrohlos System. A Draft Review 2007 - 2017, Department Of Fisheries (Western Australia) On Advice From The Abrolhos Islands Management Advisory Committee
Management Of The Houtman Abrohlos System. A Draft Review 2007 - 2017, Department Of Fisheries (Western Australia) On Advice From The Abrolhos Islands Management Advisory Committee
Fisheries management papers
This review contains a brief description of the Abrolhos System and its special values. It also states the goal and principal objectives for management during the next ten years (2006-2016), along with updated strategies to achieve these objectives. The document succinctly outlines the direction for multiple use management of the Houtman Abrolhos Islands as determined by the Abrolhos Islands Management Advisory Committee (AIMAC). The Committee’s role is to advise the Minister for Fisheries on management of the Abrolhos Islands and the Abrolhos Islands Fish Habitat Protection Area.

The northern bobwhite quail (Colinus virginianus) is an important game bird that is intensively managed for hunting recreation in the southeastern United States. Despite interest regionwide, populations have been declining for much of the last 40 years (Brennan 1999). Population declines in the Southeast have occurred as a result of widespread habitat loss associated with land-use changes (Brennan 1999). These land-use changes include both conversion from agricultural to forest landscapes and changes in forest management practices, which result in dense forest canopies that shade required ground vegetation (Brennan 1999, Rollins and Carroll 2001). In addition, low-quality habitats may …
Vegetative And Invertebrate Community Characteristics Of Conservation Reserve Program Fields Relative To Gamebirds In Western Kansas, Elizabeth D. Doxon, John P. Carroll

We examined vegetation and invertebrate characteristics, including insect biomass, insect-prey, six Families and seven Orders in four varieties of Conservation Reserve Program (CP10, improved CP10, CP2 and CP25) and wheat fields in western Kansas during Jun. and Jul., 2004 and 2005 relative to gamebird chick ecology. CP10 fields had less bare ground and forbs compared to the other Conservation Practices and CP25 fields had lost much of their original forb component by the end of the study. Although there was little forb component, CP10 fields had high invertebrate biomass. However, CP10 fields demonstrated sizeable declines in the estimated effect size …
Nutrient Cycling In Forage Production Systems, David A. Wedin, Michael P. Russelle
Nutrient Cycling In Forage Production Systems, David A. Wedin, Michael P. Russelle

In most forage production systems, the nutrients needed for plant growth are provided by microbially mediated breakdown and release of plant-available mineral nutrients from dead plant tissues, livestock excreta, soil organic matter, and geochemically bound mineral forms. Even in fertilized forage systems, determining appropriate fertilizer application rates requires a "systems" approach on the part of the manager (e.g., Di and Cameron, 2000; Rotz et al., 2002). Fertilizer additions are simply one input in the system of inputs, outputs, pools, and fluxes that characterize nutrient cycling in a particular ecosystem.
