  Poster Paper:  All of a flutter: heart-rate effects in response to diclofenac in adult (female) Moina macrocopa Strauss 1820 Introduction: context and choice of organism Heart rate studies have been performed on crustaceans since their internal structure was seen to have an oscillating heart-like structure in the early days of microscopy. In 1894, J.W. Pickering (Pickering, 1894) used Daphniae [sic.] to explore the effects of a range of medications on simple cardiac structures, and specifically to mimic experiments in vertebrate embryos. By the third decade of the 20th century, Daphnia was established as a model of pharmaceutical studies, so much so, that Viehoever (1936) termed Daphnia “the biological reagent”. More detail on the overall history of biological studies into Daphnia may be found in Shaw et al. (2008) however suffice it to say that Daphnia and its relatives including Moina would form an indispensable tool in toxicological, pollution, and pharmaceutical research.
