Prey-specific encounter rates and handling efficiencies as causes of prey selectivity in ambush-feeding hydromedusae
We examined the foraging process in the jellyfish Sarsia tubulosa feeding on three types of prey: cirripede nauplii, cypris larvae, and Acartia tonsa copepodites. Clearance rate was used as measure of prey selectivity. To estimate maximal clearance rate (Fmax), we used a predictive encounter model with input parameters quantified from video observations. Both encounter rate and handling efficie...

متن کاملFeeding behaviour of the nauplii of the marine calanoid copepod Paracartia grani Sars: Functional response, prey size spectrum, and effects of the presence of alternative prey
Laboratory feeding experiments were conducted to study the functional response and prey size spectrum of the young naupliar stages of the calanoid copepod Paracartia grani Sars. Experiments were conducted on a range of microalgal prey of varying sizes and motility patterns. Significant feeding was found in all prey of a size range of 4.5-19.8 μm, with Holling type III functional responses obser...
متن کاملFlexibility in locomotor-feeding integration during prey capture in varanid lizards: effects of prey size and velocity.
Feeding movements are adjusted in response to food properties, and this flexibility is essential for omnivorous predators as food properties vary routinely. In most lizards, prey capture is no longer considered to solely rely on the movements of the feeding structures (jaws, hyolingual apparatus) but instead is understood to require the integration of the feeding system with the locomotor syste...
متن کاملContextual Flexibility: Reassessing the Effects of Prey Size and Status on Prey Restraint Behaviour of Macrostomate Snakes
Animals interact with their environment in diverse ways. Behavioural flexibility, the ability to vary the deployment of behavioural patterns in response to different situations, is an important aspect of the phenotype of many organisms (Caro & Bateson 1986; Helfman 1990; Gordon 1991; Kieffer & Colgan 1993; Mercier & Lenoir 1999). The aggregate set of available behaviours, commonly known as a be...
