Feeding Behavior of Juvenile and Adult Marine Planktonic Copepods: Cyclopoida and Calanoida

环足类和水蚤类的口部形态表明，这两个目的成虫之间和成虫之间的取食行为有很大的差异。由于无节幼体在肌肉结构上的基本差异，它们在早期阶段也应该有所不同，它们在不同的阶段开始进食。然而，关于这两个群体的代表如何获取食物的信息有限，特别是对于海洋类摆动类。对环翅目的两个属(Oithonidae和Oncaeidae)的取食率研究强调它们是杂食性/肉食性的。将测定这两个属的无节幼体、幼体和成年雌性的摄食行为。基本观察将包括描述颗粒收集、捕获和摄取的模式，感知到食物颗粒的距离，以及捕获之间的游泳/移动行为。为了进行比较，将对两种鱿鱼进行相同的观察(Centroages和Thema)。前者产生微弱的摄食电流，成年后更多的是肉食而不是草食。后者产生更强的摄食电流，更像是食草动物而不是食肉动物。

The morphology of the mouth parts of cyclopoid and calanoid copepods suggests great differences in feeding behavior between and among adults of these two orders. Differences should also be expected in their early stages because of basic differences in musculature in their respective nauplii, and they begin to feed at different stages. However, information as to how representatives of both groups obtain their food is limited, especially for marine cyclopoids. Feeding rate studies on two genera of cyclopoids (Oithonidae and Oncaeidae) emphasize that they are omnivorous/carnivorous. Feeding behavior of nauplii, juveniles and adult females of these two genera will be determined. Basic observations will include describing modes of particle gathering, capture and ingestion, distances from which food particles are perceived and swimming/moving behavior between captures. For comparison purposes, the same observations will be made on two species of calanoids (Centropages and Temora). The former creates weak feeding currents and is more carnivorous than herbivorous as adults. The latter creates stronger feeding currents and is more of a herbivore than a carnivore.
