Feeding Selectivity and Habitat Usage of <i>Esox americanus</i>
… exhibited differing intensities of selectivity among prey types. Field selectivity was assessed from 18 sites by clustering species of potential prey assemblages into a series of functional groups using a suite of traits representing species’ habitat affinities and morphological …

Effects of Particle Surface Properties on Feeding Selectivity in Suspension-Feeding Bivalve Molluscs
… surface properties upon selection by suspension-feeding bivalves were examined. The charge and wettability of several different types of 10-µm spheres were determined. Microspheres with different surface characteristics were fed to oysters (<em>C. viriginica)</em> and mussels (<em>M. …

Laboratory studies on the feeding behaviour of juvenile Cape horse mackerel, Trachurus trachurus capensis
… conducted on juvenile horse mackerel to examine feeding selectivity and rates of zooplankton consumption of two size classes of fish. Fish were fed a variety of natural zooplankton assemblages and sequential subsampling of water in the experimental tanks provided estimates of prey concentration. …

Development of an Algal Diet for Rearing Juvenile Freshwater Mussels (Unionidae)
Feeding selectivity by the rainbow mussel (Villosa iris) was examined for three age groups; 2-3 days old, 50-53 days old, and 3-6 years old. The mussels were fed an algal diet consisting of Scenedesmus quadricauda (22.3 - 44.5 μm), Nannochloropsis oculata (2.8 – 8.1 μm), and Selenastrum …

Juvenile Green Turtle (chelonia Mydas) Foraging Ecology:feeding Selectivity And Forage Nutrient Analysis
… whether juvenile green turtles showed a feeding preference by comparing prey items in the diet to the availability of those items in the habitat, 2) identify species for which there was selection or avoidance, 3) identify nutritional factors determining selection or avoidance of prey …

Foraging Ecology of Parrotfishes in the Greater Caribbean: Impacts of Specialization and Dietary Preferences on Marine Benthic Communities
… parrotfishes), all of which belong to a single feeding guild but represent a range of dietary specialization, respond to changes in the abundance of preferred food items. We conducted behavioral observations of parrotfishes in two regions of the Greater Caribbean, and compared consumption rates, …
