Data for: Bi-modal response strategy in Daphnia to ambush predation risk|水生生态数据集|捕食风险数据集

Predation, a well-established major selective force, can manifest through either consumptive or non-consumptive effects. The relative impact of such effects is predicted to vary depending on the predator hunting strategy. In aquatic systems, great attention has been paid to coursing predators, such as fish, and their effects on the behaviour of zooplankton. However, less information is available regarding more ambush-style predators. To remedy this paucity, we utilised a 3D-tracking platform to record groups of Daphnia magna under control or predation risk conditions from the ambush, invertebrate predator Erythromma najas. This design allowed us to test if there are anti-predator responses in multiple metrics of swimming behaviours. Furthermore, we recorded actual predation events allowing the distinction between predator exuded info-chemicals and those produced during the predation event. We demonstrate that predation risk was greatest for those that swam at 85% of the available depth ..., The information on collection of data is found in the associated manuscript and the only processing in is the concatenation of individual files into a single dataset, included here., The data file is .cs so may be opend and read by many different applications depending on the users preference., GENERAL INFORMATION
