The interaction between the acmaeid limpet, Collisella instabilis
and the subtidal laminarian, Pterygophora californica involves positive
effects on the limpet population and subtle positive or null effects on
the kelp. Collisella, which is found only on Pterygophora and another
kelp, Laminaria dentigera (Kjellman, 1889), may exploit several features
of the...
Investigations about the feeding ecology of a consumer
can facilitate prediction of its effects on prey populations
and the biological community. The aspects of feeding
ecology that are important to predicting consumer effects
include foraging movements, feeding preference and
selectivity, and the effects of physical factors on foraging
behavior and...
