According to optimal foraging theory.. organisms will have a tendency to select the smallest prey available if they are common, rather than exert more energy in capturing larger prey. predators will always maximize their rate of energy gain when they forage for more than 1 prey type. an organism can gain unlimited resources if it invests more energy into increasing its food intake. a predator will include prey with high handling times in their diet as long as their energy of rate intake increases.
Optimal foraging theory can make predictions about an animal’s food choice. Which of the following is the most accurate statement about optimal diet breadth as resource quality, handling time and distribution changes? As handling time increases, animals should specialize As the distance between resources increases, animals should generalize As the energy content of the resources increases, animals should generalize As the distance between patches increases, animals should stay longer in a patch The following diagrams show four distribution patterns of resources. Each circle represents one unit of a resource, say, a food item. For which of these distributions would the Marginal Value Theorem be useful for making predictions about optimal foraging behavior.

This is a system dynamics model of the Lotka-Volterra Predator-Prey model. The two stocks in the model are prey and predators. The _________ __________ of the prey and predators change in response to the inflows ______and outflows_____. Each iteration the stock changes by the inflows minus the outflows, or ___________________________. The ___________ feedback is the result of the interconnections between the predator and the prey. The prey _________ the predators, and the predators ________the prey. This simple interaction allows the system to _____________. When the predators ________the prey, the small numbers of prey leads to the predators __________. With a __________ in predators the prey_____________, and the cycle continues.
What is the best description of the original Lotka-Volterra predator-prey model? Nis prey, P is predator. a is rate of consumption, f is conversion of prey to predator, and q is the mortality rate of the predator. dP rN - aNP= = faNP - qP dt dt Type 1 functional response with density-dependent prey and density- independent predator Type 1 functional response with density-independent prey and density- independent predator Type 1 functional response with density-dependent prey and density-dependent predator Type 1 functional response with density-independent prey and density- dependent predator
Optimal foraging theory suggest that a predator selects among possible prey based on their relative profitability (energy gained per unit of energy expended). Do you think that predator directly evaluate the profitability of potential prey items before selecting or rejecting them ? If not, how mighta foraging strategy evolve ?
Thinking about the Lotka-Volterra predator-prey model, what effect should an increase in searching efficiency (a) have on the maximum prey population? Increase Decreasė No change < Previnus V Finish
Much of animal behaviour theory is rooted in optimality, using this theory and thinking about territory size, construct a well-labeled graph below: sketch two lines (one for costs, one for benefits), with an asterisk (or symbol of your choosing) indicate the theoretical optimal territory size and in one sentence, explain why that particular territory size is optimal . Territory Size Costs/benefits
You are studying the diet of American bison. You gather the data in the graph below on the effort bison invest (gray bars, left hand Y-axis) in obtaining different types of grass (X-axis) and the energy content in calories of the grasses (white bars, right hand Y-axis). According to these data, which type of grass would optimal foraging theory predict bison choose? Handling time (seconds) Grama Broma 30 Fescue 20 10 Bluestem Fescue Switchgrass Bluestem Grama Switchgrass Broma 9 6 3 0 (Calories) Energy content
During mating season, males of certain species will perform displays of aggression toward other males when approached while they are courting a female. This type of behavior is an example of altruistic behavior agonistic behavior fixed action pattern polygamous behavior predatory behavior The capacity to make changes in behavior on the basis of experience is known as a fixed action. learning. habituation. conditioning. Which of the following statements is not true concerning the optimal foraging theory? forager tries to maximize the energy gained forager tries to minimize the energy expended forager secures essential nutrients forager tries to minimize the risk of getting eaten while gathering food forager contributes to the growth of its population by gathering food
The yellow perch is a fish found in freshwater lakes. It is a generalist predator, consuming a variety of prey species, including crayfish, small fish, insect larvae and snails. You examine the predation rate of yellow perch on snails, and obtain the following data. Identify the type of functional response, and a plausible reason for why it has that type of response. 60- 40- 20- Perch Predation Rate
Based ONLY on the feeding relationship in the picture, which one is the limiting factor for the insect? * Insect Mouse Owl Plant Herbivore/ Consumer Omnivore/ Carnivore/ Producer Consumer Consumer O Producer Omnivore O Carnivore Herbivore
5) According to the optimal foraging theory, which of the following is NOT one of the factors that influence the likelihood of a predator's selecting a prey type? Question 5 options: search time required to find alternative prey types profitability of the prey type handling time energy content probability of their own predation
