Summary Introduction
To explain: The way in which the study of whelk-eating crows supports the optimal foraging model.
Introduction: Optimal foraging model predicts a balancing act between the benefits of nutrition and the costs associated with foraging. The costs of foraging include the risk of being eaten by predators, energy expended in locating food and the distance of the food source from the nest. The most significant cost is the risk of falling prey to predators. This is seen in the case of mule deer (Odocoileus hemionus) which feed predominantly in open areas to avoid falling prey to large predators like mountain lions (Puma concolor).

- If the rate of some process is governed by the abundance of prey individuals, we say that it is prey-dependent. Give some examples of prey-dependent processes.arrow_forwardName two other environmental factors which can affect the success of a predator.arrow_forwardYou 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?

- 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 .

Describe an example of apparent competition that does not involve a predator.arrow_forwardInterpret the following graphs: In the graphs, the number of days are 18.. 1 day is equal to 60 sec. days are taken on x-axis.

Provide examples and interpret data.arrow_forwardinterpret the following graph: In the graph, the number of days are 18.. 1 day is equal to 60 sec. days are taken on x-axis. The mean foraging times are taken on y-axis.arrow_forwardOptimal 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.

- 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 ?arrow_forwardDo the above hypothesis support the graph? Explain Foraging in a mixed-species flock scenario, the assumption is that the establishment of mixed-species flocks will enhance feeding productivity.arrow_forwardInterpret the following graphs: In the graphs, the number of days are 18.. 1 day is equal to 60 sec. For the first graph, days are taken on x-axis. The mean foraging times are taken on y-axis. For the 2nd graph, percentage of prey caught during first half of winter(1-6days) were taken on x-axis and percentage of prey caught during 2nd half of winter(7-12days) were taken on y-axis.arrow_forward
