Project Outline:The activities of dung beetles and other soil macroinvertebrates support the maintenance of healthy soils by facilitating the breakdown of dung through combined direct consumption and facilitated microbial community action, but livestock veterinary drugs such as avermectins and antibiotics threaten such ecosystem services.Although avermectins (wormers) and antibiotics are both routinely administered to livestock and may be present in dung at the same time the combinational impacts (negative or positive) of these veterinary drugs on dung beetle behaviour, reproduction, soil fauna-microbiome interactions, and associated ecosystem level consequences are likely to be substantive but have not been studied before.This project aims to address these issues to provide a better understanding of the processes involved which may help improve food security and mitigate against antibiotic resistance, biodiversity loss and climate change in agricultural environments.

项目概要：金龟子和其他大型土壤无脊椎动物的活动通过直接消费和促进微生物群落活动促进粪便分解，从而支持维持健康的土壤，但阿维菌素和抗生素等牲畜兽药威胁着这种生态系统服务。虽然阿维菌素（蠕虫）和抗生素都是牲畜的常规用药，并且可能同时存在于粪便中，但其组合影响这些兽药对蜣螂行为、繁殖、土壤动物群-微生物组相互作用的影响（负面或正面），以及相关的生态系统层面的后果可能是实质性的，但以前没有研究过。本项目旨在解决这些问题，以更好地了解所涉及的过程，可能有助于改善粮食安全，减轻农业环境中的抗生素耐药性、生物多样性丧失和气候变化。
