- Consider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 FT MT Temperature Fewer males and females will result. None of the other answers is correct. No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring. More males than females will result. More females than males will result. To Percent female O O O OGreat white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)ections: Read each question below carefully, determine correct equation to use, and calculate for the variable ng asked for in the question. Show your work. 1. A population of 20 velociraptors has 4 babies in one breeding season. However, 2 of the older velociraptors die off due to old age. What is the growth rate of this population of velociraptors? Type answer here A population of 100 mice has a growth rate of 0.2. In an exponential growth environment, what is th
- Dippers (Cinclus cinclus) are small birds that can be found along fast-flowing streams in Europe and Asia. They feed on insect larvae, especially those of caddis flies (Trichoptera), which they catch by sticking their heads under water and turning over stones. Describe the relationship between the abundance of caddis fly larvae and dippers?Why, is caddis fly larva abundance expressed as ‘relative abundance’? using the data in Table 2Some animals migrate daily, whereas others migrate seasonally. Give an example of each type of migration pattern and explain the benefit of this pattern to the organisms exhibiting it.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
- In the graph, what is the carrying capacity of the deer in this particular environment?A predator's foraging behavior can be altered by prey density is different ways (functional responses). While some predators consume more preys at higher prey density (e.g., spiders), other predators such as pelicans will slowly decrease prey consumption as prey density increases. What type of functional response will describe a backswimmer (aquatic predatory insect) that exhibits low prey consumption under low prey density, rapid prey consumption under moderate prey density that slows down at high prey density? O Type II O Type III O Type ISchmidt-Nielson calculated the swimming cost in a mallard duckand found that it was nearly 20 times as high as the swimmingcost in a salmon of the same body mass. What could explain thegreater swimming efficiency of salmon?
- Based on these graphs, and assuming head raises of European finches helps watch for predators but also has a trade-off with eating, select the statements that these graphs support. Total head raises of entire flock per minute (a) 28 24 20 16 12 8 4 4 5 Flock size 0 1 2 3 6 Individual head raises per minute (b) 12 10 8 N T 0 1 2 3 4 5 6 Flock size Time to husk a seed (seconds) As the flock size increases, individuals have less access to food 1.8 1.6 1.4 1.2 1.0 1 C 01 2 3 4 5 6 Flock size O The larger the size of the flock, the smaller the fitness of each individual As the flock size increases, individuals are able to eat more quickly The graphs support the hypothesis that there is no tradeoff at the individual level between watching for predators and husking seeds When groups are larger, individuals can spend less time watching for predators, but as a group they have spend more. The graphs support the hypothesis that there is a tradeoff at the individual level between watching for…The remains of an unknown primate were found on the forest floor. The length the humerus is 30 cm. The length of the radius is 31 cm. The length of the femur is 26 cm and the length of the tibia is 27 cm. Calculate and type or write the intermembral index: What is the inferred locomotion of this primate?If you adjust each of the four constants, one at a time, by 10%, which seems to have the greatest impact on the simulation output? Examine the Lotka-Volterra equations to explain by this constant makes such a big difference in the predator-prey system. Hint: This constant affects both the birth rate of predators and the death rate of prey.
