WebAbstract. Daphnia may respond with an array of anti-predator defences (behavioural, morphological and life history) to a chemical cue (kairomone) exuded by its predators: fish and Chaoborus.Given the wide array of potential responses, it is an interesting question whether anti-predator defences are coupled or independent of each other. WebNov 15, 2024 · Daphnia Proteomics Mass spectrometry 1. Introduction With a rising worldwide plastic production, almost 370 million tons in 2024 ( PlasticsEurope, 2024 ), the likelihood of inappropriately disposed plastic litter entering the ecosystems increases. Especially the occurrence of microplastics (<5 mm) have gained global attention. Daphnia species are normally r-selected, meaning that they invest in early reproduction, so have short lifespans. An individual Daphnia lifespan depends on factors such as temperature and the abundance of predators, but can be 13–14 months in some cold, oligotrophic, fish-free lakes.
