Summary Introduction
To review:
The selective pressure, which shapes the preference for food available in two different regions with different calorific values.
Introduction:
An animal prefers a particular food in a region based on conditions like the abundance of food, less predation risk, and less foraging time. The energy requirements of animal should be met with less foraging time and also with ability to meet nutrient requirements. This is known as optimum foraging.

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.
Describe the predation strategy (i.e., actively searching or ambush) of zebrafish under a well-lit environment.
Consider a trophiccascade with 4 levels: 1) predatory fish that consume planktivorous fish, 2) planktivorous fish that consume zooplankton,3) herbivorous zoplankton that consume phytoplankton, and 4) phytoplankton.
True or False: A reduction in predatory fish will increase the level of phytoplankton.

False

- How does a defense mechanism (behavioural, cryptic colouration, protective colouration, mimicry) affect predation and competition? a) Provide an example of a defense mechanism that you have not encountered in the course or in the online assignments. Include an image depicting the defence mechanism, describe the defence mechanism and cite your sources. b) Hypothesize how this defence mechanism may have evolved over time due to pressure from predation and/or competition.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. (Shown in image)arrow_forwardDefine predation. How does the predator-prey relationship differ from the parasite-host relationship? Why is the evolutionary race be-tween predator and prey one that the predator cannot afford to win?arrow_forward
- Give examples of evolved defenses against predation andherbivory.arrow_forwardRed-billed oxpeckers feed almost exclusively on what they can collect from the skin of large African mammals. This includes ticks and other ectoparasites, but also dead skin and blood of the mammal. The attached image shows a red-billed oxpecker sitting on the back of a warthog with a tick in its bill. A recent study found that the depletion of African mammals due to habitat loss and hunting leads to declines in oxpeckers. Researchers were interested in whether the nature of the interaction between African mammals and oxpeckers was context-dependent. They compared the effect of removal of oxpeckers in two areas in which the number of ticks on the mammals differed. Given the data described in the introduction to this section, what effect do African mammals have on oxpeckers a) Positive b) negative c) neutralarrow_forwardRed-billed oxpeckers feed almost exclusively on what they can collect from the skin of large African mammals.

Researchers were interested in whether the nature of the interaction between African mammals and oxpeckers was context-dependent. They compared the effect of removal of oxpeckers in two areas in which the number of ticks on the mammals differed. In area 2, stomach content data of oxpeckers showed they consumed ~400 ticks per day. Cows were infested experimentally with large numbers of tick larvae and then oxpeckers were introduced at different stages in the tick life cycle (larvae; nymph; adult). They counted the number of adult ticks that dropped off the…arrow_forward
- Why does central place foraging cause animals that travel farther to bring back larger amounts of food?arrow_forwardIn spadefoot toads there are two forms of the tadpoles: omnivores and carnivores. Environmental factors such as population density, oxygen concentration, and availability of food determine which form any particular tadpole takes. Consider the situation below. A single pair of toads produces a fertilized group of eggs in a pond. The pond dries a bit creating two separate ponds, one is deep and the other is shallow. All the tadpoles in the deep pond become omnivores and all the tadpoles in the deep pond become carnivores. There is a heavy rain and the ponds become connected again and the two groups of tadpoles mix together. The carnivores eat most of the omnivores and more of the carnivores become adult toads This is an example of Group of answer choices A. natural selection and evolution B. evolution only C. natural selection onlyarrow_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
- What do you think is the adaptive value of this bizarre behavior when the urchins are actively foraging on their feeding ground? Explain in terms of different adaptive behaviors to maximise growth, survival & other traits that contributes to the fitness of the species in a highly variable coastal environment. *arrow_forwardDuring the drought of 1977 on the island of Daphne Major, which of the following answers correctly explains why birds with larger beaks had a competitive advantage over other individuals? These birds were able to hold more water. These birds were able to fight off birds with smaller beaks more successfully. These birds were able to smell and locate nesting sites with more accuracy. Birds with larger beaks were better able to utilize the large seeds.arrow_forwardWhich of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forward
