AbstractFull Text

The success of a weed incursion response ultimately depends on the ability to find and kill individual plants. Understanding detectability will allow development of operational models to guide eradication efforts by allocating resources as efficiently as possible. We present the basics of search...

Abstract

Government funding to protect native plant communities is usually limited. For cost effectiveness, priority sites for conservation must therefore be identified and funds allocated to protect these sites according to the quantity of communities conserved per dollar of cost. In 1999, invasion of...

Abstract

Conazoles are fungicides used as agricultural pesticides and pharmaceutical products. We investigated whether a common core of toxicological and transcriptional responses underlies the observed carcinogenic effects of three conazoles: cyproconazole, epoxiconazole, and propiconazole. In studies...

Abstract

Invasive organisms often exist at low densities at the beginning and end of eradication programs. As a consequence, such organisms are often difficult to find, particularly if they are dispersed long distances to unknown locations. In such circumstances, large amounts of money can be spent...

Abstract

The detectability of invasive organisms influences the costs and benefits of alternative control strategies, and the feasibility of eradicating an infestation. Search theory offers a mathematically rigorous framework for defining and measuring detectability taking account of searcher ability,...

AbstractFull Text

This paper provides an overview of the problem of weeds in Australia and then proceeds to identify the range of economic impacts these weeds have on agricultural land (in terms of financial costs, yield losses and surplus losses), on national parks and natural environments, public lands (public...

Abstract

This paper examines policy alternatives that may reduce the adverse environmental effects associated with intensive agriculture in the EC. The specific emphasis is on the potential effects that setting aside additional cropland and further reducing stocking rates in the EC (over and above the...
