The feeding ecology of deposit-feeding holothurians
… classes of holothuroidea and reflect the mode of feeding.<br/><br/>Holothurian tentacular structure is used to separate the group at the subclass or order level (Pawson, 1966). Dendritic, tree-like tentacles are used by suspension-feeding holothurians to filter particulate matter from the water; …

The feeding ecology and behavior of wigeon (Anas penelope)
… of body size on energy intake. The strategy of feeding for long periods (as much as 17 hours per day) to increase food intake seems to be very important in this species. Feeding site selection was investigated as this is an obvious way to increase nutrient intake. Wigeon show clear preference …

Feeding Ecology of Invasive Catfishes in Chesapeake Bay Subestuaries
… subestuaries of the Chesapeake Bay, where their feeding ecology and potential impact on native species was largely unknown. We collected stomach contents from 16,110 Blue Catfish at 698 sites in three large subestuaries of the Chesapeake Bay (James, York, Rappahannock rivers). Cumulative prey …

Studies of the foods and feeding ecology of wading birds.
… birds is described including the time spent in feeding. The feeding areas are described together with the foods taken from gut and pellet analysis and direct observation. The distributions of invertebrates, and especially those of major importance as wader food, are described as well as the …

Feeding ecology and habitat of the Protea seedeater Serinus leucopterus
… involved a description of the habitat and the feeding niche (sensu Whittaker et. al. 1973) of the protea seedeater, and an assessment of factors contributing to the ecological segregation between the protea seedeater and its congeners in the south-west Cape biotic zone. No similar study of an …

Burrowing and feeding ecology of the ghost shrimp Biffarius arenosus (Decapoda: Callianassidae)
… This thesis investigated the burrowing and feeding ecology of a population of shrimps inhabiting an intertidal sandflat in Western Port, Victoria.

Feeding Ecology of Fishes in a South Dakota Power Plant Cooling Reservoir
<p>The food habits of bluegills (Lepomis macrochirus), black bullheads Ictalurus melas), and muskellunge (Esox masquinongv) in the Big Stone Power Plant cooling reservoir were studied from January through December 1979. The diet of 794 bluegills >50 mm TL was dominated by vegetation, planktonic …

Larval development and feeding ecology of Hermissenda crassicornis (Eschscholtz) and Aeolidia papillosa (Linnaeus)
… larval shell type (Thompson, 1961) and on larval feeding behavior (ie. lecithotrophic vs. planktotrophic larvae). I agree with Thompson's (1967) distinction between direct and lecithotrophic developmental types in the sense that they represent ecologically diverse ontogenies.</p><p>The major …

Using feeding ecology to influence captive Slow Loris (Nycticebus spp.) nutrition and husbandry
… 2014 to June 2015 I collected behavioural and feeding data on 17 radio-collared wild Javan slow lorises near Cipaganti, Indonesia. Food samples were collected and analysed for proximate and fibre analyses. Our diet trials were conducted in a rescue centre where we introduced gum into their …

Feeding ecology of age-o smallmouth bass in the New River, West Virginia
The purpose of this study was to determine the food habits of age-O smallmouth bass (Micropterus dolomieu Lac~p~de) in the New River and to examine spatial, temporal, and size-related differences in foraging success. Understanding factors that regulate foraging success of age-O smallmouth bass may …

The Feeding Ecology of Yucatán Black Howler Monkeys (Alouatta pigra) in Mangrove Forest, Tabasco, Mexico
… on the relationship between the behavioral ecology of the monkeys and the diversity, distribution, and nutritional content of mangrove plants. After observations and plant collection over the wet and dry seasons, I found that the mangrove forest was very low in diversity, dominated by only …

Feeding Ecology and Factors Influencing Growth and Recruitment of Channel Catfish in South Dakota Reservoirs
… address the lack of understanding of the basic ecology of Channel Catfish in South Dakota we studied nine South Dakota reservoirs (small impoundments, tributary-storage reservoirs, mainstem Missouri River reservoirs) to 1) identify and quantify Channel Catfish diets and potential predatory …

Juvenile Feeding Ecology and Life History in a Neotropical Primate, the Squirrel Monkey (Saimiri Sciureus)
… factors directly related to juvenile foraging ecology, such as high starvation risks due to feeding competition with adults in the group or time needed to develop foraging skills. Other explanations argue that earlier maturation is negatively correlated with adult reproductive success, and that …

The feeding ecology of curlew sandpipers "Calidris Ferruginea" in the South-Western Cape, South Africa
Spatial and temporal changes in the distribution of food organisms potentially available to curlew sandpipers Calidris ferruginea at Langebaan Lagoon (33°s, 18°E), South Africa, are described for the period February 1974 - March 1975. Seasonal changes in the diet of curlew sandpipers foraging in …

Age, movements, and feeding ecology of northwest Atlantic white sharks estimated from ecogeochemical profiles in vertebrae
… exposure. In this thesis, I investigate the ecology of the understudied northwest Atlantic (NWA) white shark population by applying several ecogeochemistry techniques to their vertebrae. I generate the first radiocarbon (Δ14C) age estimates for adult white sharks, dramatically extending the …
