Predatory interaction strengths are highly context-dependent, and in temporary aquatic ecosystems, may be affected by water volume changes. We examine the influence of water volume on Lovenula raynerae (Copepoda) functional responses towards two temporary pond prey types. Daphnia prey risk was not affected by increasing water volume, whereas for Culex prey risk was reduced. Accordingly, water volume changes through the hydroperiod may have species-specific effects on prey, with implications for population persistence under environmental change.

水量不同地改变了桡足类对两种猎物的捕食能力

捕食性相互作用强度高度依赖于环境，并且在临时水生生态系统中，可能会受到水量变化的影响。我们研究了水量对 Lovenula raynerae（桡足类）对两种临时池塘猎物类型的功能反应的影响。水蚤的猎物风险不受水量增加的影响，而库蚊猎物的风险却降低了。因此，水量时期的水量变化可能对猎物产生特定物种的影响，对环境变化下的种群持久性产生影响。
