Correctly Cited? Can you spot and correctly modify the incorrect citations in the following paragraphs? Currently over 6 million doses of endectocides (predominantly ivermectin, a persistent, broad-spectrum antiparasitic drug) are administered annually - mainly to young cattle - in the Republic of Ireland (Murphy, 2000; Daly, 2002.). Most of the ivermectin is ultimately eliminated in the faeces where it is an effective insecticide, controlling the larvae of dung-breeding flies (Madsen et al. 1990; Hill, 1995, Fahy, 1999). However, because of its potency and broad spectrum of activity, concerns arise in regard to unintended environmental effects on non-target organisms, notably beneficial groups such as dung beetles and earthworms whose activities are important for the decomposition of dung pats (Holter, 1996, Holter, 1997, Holter 1998, Fahy, 1999; Holter and Sommers, 1998). Since cattle dung represents a major source of organic nitrogen in intensively-grazed pasture, “any effects of ivermectin on dung fauna and dung decomposition could have significant implications for nitrogen cycling”. Effects of ivermectin on the ecology of the dung fauna, dung decomposition and nitrogen cycling have each been studied in several separate studies. As Fahy, 1999 pointed out “there is an urgent need for an integrated systems-level approach” to such studies. The Burren, Co. Clare is an internationally valuable habitat. A number of threats are perceived to be affecting the extent, distribution and quality of ecological habitats in the Burren (Dunford & Feehan, 2001). While there is considerable anecdotal evidence, discussions about i) changes in the habitats of priority conservation value and ii) the relationship between the vegetation of the Burren and agricultural management appear to be based on few objective data (but see O’Donovan 1987; Dunford 2001). The aim of this project is the provision of an integrated and comprehensive database (stored in digital form in a Geographical Information System) to facilitate agri-environmental evaluation and research in the Burren. As such, the proposed project would make considerable progress towards realising the recommendations of Bohnsack and Carrucan, 1999, and would establish a database and a framework for future monitoring.
