The Role of Filter Feeders in Flowing Waters
Net-spinning trichopteran larvae are used as examples of filter-feeding stream insects to show that various species feed upon a range of particle sizes. Evolution of individual species has resulted in cropping various particle sizes of drifting stream seston. Mechanisms of how this is achieved are discussed. The evolutionary diversity of filter feeders has important consequences for stream ecos...
متن کاملNearby boundaries create eddies near microscopic filter feeders.
We show through calculations, simulations and experiments that the eddies often observed near sessile filter feeders are frequently due to the presence of nearby boundaries. We model the common filter feeder Vorticella, which is approximately 50 microm across and which feeds by removing bacteria from ocean or pond water that it draws towards itself. We use both an analytical stokeslet model and...
متن کاملModelling And Simulation Of Filter Adaptation By Daphnia
A model of feeding adaptation of a filter feeder in the framework of a pelagic ecosystem is constructed by modifying the simplified ecosystem model AQUAMOD for the presence of several different sized species of algae. Stability analysis of equilibria and some numerical simulation is given. It is shown that Hopf bifurcation may occur depending on filtration rate. Also the assumption that filtrat...
متن کاملMaternal food quantity affects offspring feeding rate in Daphnia magna.
Maternal effects have wide-ranging effects on life-history traits. Here, using the crustacean Daphnia magna, we document a new effect: maternal food quantity affects offspring feeding rate, with low quantities of food triggering mothers to produce slow-feeding offspring. Such a change in the rate of resource acquisition has broad implications for population growth or dynamics and for interactio...
