This 4-year study can be broken down into 5 main areas:
1. The impact on dung fauna and dung decomposition of conventional wormers (anthelmintics) used to
control gastrointestinal parasites. Products tested include ivermectin, cydectin and Zolvix.
2. The impact on dung fauna and dung decomposition of alternative supplements
marketed for livestock parasite control.
These supplements include nematode-trapping fungi, Verm-X herbal
formulation, diatomaceous earth, chicory, garlic, a homeopathic product and copper boluses.
3. The importance of dung beetle species richness and functional group identity on the ecosystem service of dung decomposition, and the impact of ivermectin on such patterns.
4. The relative sensitivity of north temperate dung beetles to ivermectin. What does this mean for the ecosystem service they provide?
5. The functional efficiency of (a) earthworms, (b) slugs, (c) 2 species of dung beetle and (d) water beetles in dung decomposition.
