Ecology of Vertebrate Nutrition
نویسنده
چکیده
All vertebrates require certain amounts of energy, protein and ‘essential’ nutrients. Dietary sources of energy include carbohydrates, protein and fat. Dietary protein is necessary for satisfying an animal’s protein requirements. Certain dietary nutrients are classified as ‘essential’ because they are required for synthesis or functioning of crucial chemical compounds, yet they cannot be synthesized by the organism in sufficient amounts to satisfy requirements. Thus, essential nutrients must come from diet. For most birds and mammals, about 38 nutrients are required in the diet including 10 essential aminoacids, 1–3 essential fatty acids, 13 vitamins, and at least 14 essential minerals (Robbins, 1993;Murphy, 1996).

متن کاملNutritional physiology and ecology of wildlife in a changing world
Over the last century, humans have modified landscapes, generated pollution and provided opportunities for exotic species to invade areas where they did not evolve. In addition, humans now interact with animals in a growing number of ways (e.g. ecotourism). As a result, the quality (i.e. nutrient composition) and quantity (i.e. food abundance) of dietary items consumed by wildlife have, in many...
متن کاملPredicting nutrient excretion of aquatic animals with metabolic ecology and ecological stoichiometry: a global synthesis.
The metabolic theory of ecology (MTE) and ecological stoichiometry (ES) are both prominent frameworks for understanding energy and nutrient budgets of organisms. We tested their separate and joint power to predict nitrogen (N) and phosphorus (P) excretion rates of ectothermic aquatic invertebrate and vertebrate animals (10,534 observations worldwide). MTE variables (body size, temperature) perf...
