Abstract
Ivermectin, a commonly used parasiticide, is known to affect dung beetle abundance when present in cattle dung. In this experimental study, we explicitly manipulated ivermectin concentrations in dung pats to examine its effects on dung beetle abundance, soil properties, and plant growth throughout the growing seasons of spring and summer in a western South Dakota grassland. Dung pats containing zero, low (2 mg/kg), and high (10 mg/kg) concentrations of ivermectin were strategically placed in the grassland in summer 2019 and spring 2021. Over a period of 63 days, we monitored changes in the nitrogen content of dung, soil, plants, as well as the abundance of dung beetles, and plant biomass. Our findings indicated that beetle abundance was 50% greater in dung pats without ivermectin, especially when the dung was fresh. However, ivermectin concentrations did not significantly alter the nitrogen content in dung and plants across both seasons, nor was there a discernible effect on plant biomass, despite the pronounced impact on dung beetle abundance.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
