Año: 2023;

Sound-generating human activities have considerably increased ambientnoise levels in marine and freshwater ecosystems across the globe.Anthropogenic, human-made noise is an issue of international concernand rising in ambient sound levels may have negative consequences onaquatic animals at the individual and community level. Anthropogenicnoise can negatively affect the behavior of aquatic animals in severalways. While some studies have addressed the effects of noise on fishspecies, there are considerable gaps in our understanding of the effects ofnoise more widely, especially on invertebrates. Our interest lies in theeffect of noise on the “lower levels of food web members,” i.e., smallcrustaceans such as the red cherry shrimp (Neocaridina davidi), as modelfor the link between trophic levels. The red cherry shrimp is a gregariousspecies, abundant in freshwater habitats, and native to Asia. The redcherry shrimp has economic importance in the ornamental trade andecological threat as a potential invasive species; however, its behavioralperformance in response to anthropogenic noise is unknown. This chapterdetails the effect of sound exposure on shrimp under laboratoryconditions. The findings revealed that noise impact assessments oninvertebrates are critically important for understanding howanthropogenic noise alters food webs and reverberates throughcommunities.
