Summary Introduction
Introduction:
Optimal foraging theory is a model that helps to determine the animal behavior while searching for food. Food provides energy to the animal, but foraging or searching and capturing of food needs both energy and time. Optimal foraging theory suggests that natural selection favors those animals whose foraging behavior is such energetically efficient that their increased energy reserves result in increased reproductive success.

Noisy begging by nestlings to be fed by a parent is said to be an honest signal when it entails high costs. And if the begging calls are indeed costly, which of the following predictions is least likely to occur?
A. Parents will deliver more food in response to stronger begging.
B. A parents will provide more food in response to an offspring that cries the least.
C. Noisy crying is more likely to attract the attention of predators.
D. Begging intensity reflects the hunger level of the nestlings.

For the first graph, days are taken on x-axis.

- 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 contentarrow_forwardOptimal 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_forwardAccording 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.arrow_forward
- Interpret the patterns of following 2 graphs? The time taken on y axis are in seconds and 1 day = 60 secarrow_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. (Shown in image)arrow_forwardThis 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.arrow_forward

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_forwardDo the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.arrow_forward
