Smallmouth bass abundance and diet composition in the upper Spokane River
… increased 125 percent between 2009 and 2015. A diet survey was conducted to determine the amount of predation occurring on Redband Trout by Smallmouth Bass. No predation of Redband Trout by Smallmouth Bass was observed during the study, though only 5 young-of-the-year Redband Trout were seen …

Analyzing the diet composition of Lake Trout (Salvelinus namaycush) in Upper Priest Lake
<p>Lake Trout (Salvelinus namaycush) were intentionally introduced to the Priest Lake system in 1925 with the intentions of creating a recreational fishery. As the Lake Trout population increased within this system, the native Bull Trout (Salvelinus confluentus) population began to decline. …

Effects of feeding level and diet composition on mammary growth in prepubertal lambs and mice
… treatment groups: A) fed a standard, high-energy diet, ad libitum; G) fed as group A, but treated with GH (.1 mg/kg bodyweight/d); R) fed the standard diet in restricted amounts to a target weight gain of 120 g/d; S) fed a ration including 30% of a protected fat supplement, ad libitum. Rations …

Effects of diet composition and length of feeding restriction on the locomotor rhythms of Mus musculus
… consuming either a high glucose or high starch diet. Blood glucose curves for animals under restricted feeding regimes of 1 and 5 hour lengths were determined for the two diets. Most of the locomotor activity records from animals in total darkness and a restricted feeding regime contained rhythm …

Diet composition and perceptions around food in individuals with Type 2 Diabetes Mellitus following a long-term low carbohydrate high fat diet
… and mortality. Low carbohydrate high fat (LCHF) diets may be particularly effective and sustainable for the treatment of T2D and have become a popular ‘self-therapy’. This study investigates the real-world dietary composition and potential effects of a long-term LCHF diet on T2D. Materials and …

The vitamins A and C status of the rat and guinea pig, as influenced by the level of vitamins A and C intake, diet composition, calorie intake and exposure to cold.
… technique and a vitamin A deficient test diet of a different composition. We found that the onset of vitamin A deficiency at room temperature occurred ten days earlier on a yeast-free vitamin A deficient test diet. In addition, the control animals on the new diet had a distinct tendency …

Nutritional Condition of White-Tailed Deer in the Central Black Hills, South Dakota: Influence of Habitat and Elk Competition
… and winter ranges. Habitat variables, deer diet composition and quality, and nutritional condition were compared between the northern Black H ills (NB H) and the CBH. Also, elk diet composition and quality, and dietary overlap between elk and deer was determined. Habitat variables were …

Seasonal Differences in Diet of Two Predatory Fishes in Relation to Reef Type in the Inshore Northern Gulf of Mexico
… study were to establish how abundance (CPUE) and diet composition (%IRI) changes seasonally within Spotted Seatrout, <em>Cynoscion nebulosus</em>, and Sand Seatrout, <em>Cynoscion arenarius</em>, to view which trophic levels are interacting in relation to different reef type (high relief profile …

Naturalization of Salt Marsh Restoration Sites in the Elizabeth River, Virginia, Assessed by Feeding Activity and Trophic Level of Mummichogs (<i>Fundulus Heteroclitus</i>)
… per site to measure gut fullness and identify diet composition. Muscle and liver tissue were removed from additional fish and prepared for stable isotope analysis at UC Davis. The diet composition of the restored salt marsh sites included blue-green algae as a major diet item, which was not the …

Diet analysis of wintering waterfowl in the Southeastern United States in relation to ecoregion, habitat, and guild
Wintering waterfowl diet has been studied across North America to gain a better understanding of their foraging habits and feeding ecology. There is a need for a better understanding of waterfowl foraging based on ecoregion, guild, and habitats of wintering waterfowl, especially within the …

Estimating Trophic Position of Lake Oahe Walleye Using Stable Isotope Analysis
… in reduced walleye growth. Although traditional diet studies are useful for determining changes in prey use, they can be time and labor intensive. Furthermore, they offer only a snapshot of recent feeding patterns when populations are sampled infrequently. I used stable isotope analysis to …

The ecology of larval and juvenile fishes in lowland rivers, with particular emphasis on foraging
… study revealed diel variation in fish species composition, prey availability, diet composition, feeding activity and prey selection of larval and 0+ juvenile fishes. Five surveys were carried out in total, until the fishes reached juvenile stage, in the River Trent. There was circumstantial …

Determining the Trophic Role of Red Snapper (Lutjanus campechanus) in Mississippi State Waters Using Stomach Content and Stable Isotope Analysis
<p>The goal of this study was to determine the diet composition, trophic position and ecological role of red snapper <em>(Lutjanus campechanus</em>) in Mississippi state waters utilizing stable isotopes (δ<sup>13</sup>C and δ<sup>15</sup>N) and stomach content analysis. Stable isotope analysis of …

Street-wise : does prey abundance buffer black sparrowhawks (Accipiter melanoleucus) from the negative health impacts of urbanisation?
… this might be driven by differences in diet and prey availability across the urban spectrum. Thus, we explored this potential mechanism by examining diet composition and assessing prey abundance within different territories and habitat types. The health of nestling Black Sparrowhawks was …

Exploring the breeding diet of the Black Sparrowhawk (Accipiter Melanoleucus) on the Cape Peninsula
This study investigates the diet of breeding Black Sparrowhawks (Accipiter melanoleucus) on the Cape Peninsula of South Africa. Macro-remains of prey were collected from below and around the vicinity of nests throughout the breeding seasons of 2012 and 2013. These prey items were then identified …
