摘要

我们探讨了觅食偏好的差异对水生食肉半翅目动物长期物种共存的潜在影响。我们假设,捕食性半翅类动物会根据其形态而具有不同的觅食偏好。我们使用了一个猎物选择实验来检验Belostoma flumineum、Pelocoris biimpressus和Ranatra australis是否在对两足类、豆娘类和笠螺类猎物的相对偏好上存在差异。我们发现,捕食者的觅食偏好具有互补性,B. flumineum偏好蜗牛,P. biimpressus偏好豆娘,R. australis偏好片脚类动物。我们的研究结果表明,水生半翅目昆虫不同的觅食偏好可能会促进它们在水生系统中的共存,但需要注意的是,研究需要探索实验室实验中发现的模式是否反映了自然界中的相互作用。

Prey Preferences for Three Aquatic Hemipterans Provide Insights About Their Coexistence

Prey Preferences for Three Aquatic Hemipterans Provide Insights About Their Coexistence

We explored the potential of differences in foraging preferences to contribute to long-term species coexistence in aquatic predatory hemipterans. We hypothesized that predatory hemipterans would have distinct foraging preferences informed by their morphology. We used a prey choice experiment to test whether Belostoma flumineum, Pelocoris biimpressus, and Ranatra australis differed in their relative preferences of amphipod, damselfly naiad, and physid snail prey. We discovered that the predators showed complementarity in their foraging preferences with B. flumineum preferring snails, P. biimpressus damselfly naiads and R. australis amphipods as prey. Our results suggest that the disparate foraging preferences of aquatic hemipterans may facilitate their coexistence in aquatic systems but caution that studies need to explore whether patterns uncovered in the laboratory experiment reflect interactions in nature.
