What is the Predator Release Hypothesis? Explain how it works.

This discussion provides you with some data about four pools of guppies. These pools have different turbidity (i.e. cloudiness), make-up of predators, depths, locations, numbers of guppies, and contain bright or drab-colored male guppies. Observe the data given about the pools and note any patterns you see that might relate to the color patterns of the male guppies. Selection pressures are an aspect of the environment that causes a change in characteristics over time. Then you will decide which of the selection pressures on the male guppies have resulted in the variations in color patterns you see in the data. 1. Try to give a concise (short) but rich description of each of the four guppy pools   2. What selection pressures caused the variation in the color pattern of male guppies? Support your claims with evidence.  3. Is it better to be bright or drab if you are a male guppy? Support your claims with evidence.

To explain: The way in which predator-prey relationship is affected by natural selection.

The frequency of light-colored furmedium-colored furdark-colored fur increased on the north side because the mice were betterless suited for survival. The frequency of  light-colored furmedium-colored furdark-colored fur  increased on the south side because the mice were betterless suited for survival. The frequency for  light-colored furmedium-colored furdark-colored fur  became extinct in both environments because the mice could be seen  moreless  easily by predators

Your textbook uses this graph as evidence for human hunting driving early exctinctions. Highlight this evidence by interpreting the important information on the graph. Start by accurately describing the way the graph looks, then identifying and describing important numbers and trends. When discussing numbers and trends, use the units and information found on the x and y axis. Finish with a conclusion. What does it tell us about prey switching and impacts of predation on biodiversity? Partridges and other small birds Hares and other small mammals Tortoises and shellfish

The data shown in Table 1 were collected from a study of predation on rabbit warrens and nests found on different soil types across seven regions of Australia between 1996-1998. Using these data, answer the questions that follow.

Which of the following statements most accurately describes the example of species interactions for ants, plants and aphids    Question 2 options:   The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants.   The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants   The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.   The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.

Thinking about the Lotka-Volterra predator-prey model, what effect should an increase in searching efficiency (a) have on the maximum prey population? Increase Decreasė No change < Previnus V Finish

Suppose you model the interaction between the elephants and acacias using a simple Lotka-Voterra predation model, where N is the number of A. depranolobium trees, and P = number of elephants. part a:  According to the model, what happens in the short term to the elephant and acacia populations if the elephant population is lower than its own isocline, and the acacia tree population is lower than its own isocline? (Choose one.) Group of answer choices Both elephant and acacia populations will increase in size. Both elephant and acacia populations will decrease in size. The elephant population will decrease in size, but the acacia population will increase in size. The elephant population will increase in size, but the acacia population will decrease in size.   part B:    Which of the following would make this simple model more realistic? (Select all that apply.) including A. mellifera trees as a prey for elephants including other herbivore populations (such as giraffes)…

I am doing an ecology research paper on Brown Anole Lizard Distribution,  to perform my experiment I will choose 4 spots in a park such as a lake, a shaded tree, a boardwalk, and a sidewalk. then to quantify my results I will go three times a day for five weeks and count how many lizards I see in each area.  I need help thinking of a good research question? it does not have to be long.
