Question 5 options: search time required to find alternative prey types profitability of the prey type handling time energy content probability of their own predationWhat 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 predatorPrairie dogs are small mammals that live in large colonies in burrows a the ground. Prairie dogs that are near their own relatives whena predator approaches are much more likely to issue a warning bark than those that are near unrelated prairie dogs. The prairie dogs that hear a warning bark are more likely to hide in their burrows than to remain above ground. However, the prairie dog that gives the warning bark is putting itself at increased risk of being identified and killed by the predator.Which of the following presents the most likely evolutionary explanation for the behaviors described? ZP chool The barking prairie dog is alerting unrelated prairie dogs to the predator, so it is not giving any advantage to its own relatives. The failure of the individual to bark when surrounded by unrelated prairie dogs ensures survival of the individual. The warning bark changes the behavior of the related prairie dogs nearby, allowing the prairie dog's family to have increased survival and…
- Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches? Far fewer black beetles would I + Which of the five conditions of Hardy-Weinberg equilibrium would be violated in this situation? V [ Select ] Genes are now mutating. Mating is no longer random. The population size is now much larger. The population would experience natural selection pressures. There is now immigration of individuals into the population.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 .

Last checked at 6:55pm S CRead this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.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
- Whichof the following factors can stabilize predator-prey relationships by providinga prey refuge?a.An area of prey habitat where predators cannot enterb.An area of prey habitat that is isolated and difficult for predators tofindc.The occurrence of prey in numbers too large for predators to attackeffectivelyd.The ability of prey to grow to a size invulnerable to predatione.All of the choices apply.There are three chief ideas of the handicap principle: 1) Animals communicate with éach other throughn sigi must be honest, and 3) honest signals are expensive. Stotting behavior (up and down jumps gazelles exhibit when they spot a predator before the gazelle runs away) often results in the predator leaving before it attacks, presumably because the predator knows it won't easily catch that gazelle. This clearly is an example of the handicap principle based on the three ideas. True FalseA wetland is filled in in order to build some beachfront properties. This wetland was a stopping point for migratory birds along their migration (not an ultimate destination). What is a likely outcome of this scenario? The birds may experience fatigue/weakness/hunger from a lack of a resting point, which could have negative fitness consequences The birds will adjust their ultimate destination closer to make up for the missing "rest stop" The birds will be unaffected and simply go to the next wetland they encounter The birds will simply rest in the same area, just on buildings instead of in a natural habitat
