Textbook Question
Chapter 51.1, Problem 2CC
WHAT IF? Ø Suppose you exposed various fish species from the minnows’ environment to the alarm substance from minnows. Thinking about natural selection, suggest why some species might respond like minnows, some might increase their activity, and some might show no change.

1. From the animals in the figure, which species could have a positive indirect effect on the Possum?
2. If you suspect that competition between Wallabies and Bandicoots is leading to coexistence, describe an example of a piece of evidence that would support your idea.
3. If Tasmanian devils become extinct in the wild due to DFTD, name a species other than cats that you expect would change in abundance as a result. Explain how you think that species' abundance would change and why.
MAKE CONNECTIONS Commercial fisheries targetolder, larger cod fish, causing cod that reproduce at ayounger age and smaller size to be favored by naturalselection. Younger, smaller cod have fewer offspring thando older, larger cod. Predict how evolution in responseto fishing would affect the ability of a cod populationto recover from overfishing. What other reciprocal ecoevolutionary effects might occur? (See Concept 23.3.)
WHAT IF? Suppose two bird species live in a forestand are not known to interbreed. One species feeds andmates in the treetops and the other on the ground. Butin captivity, the birds can interbreed and produce viable,fertile offspring. What type of reproductive barrier mostlikely keeps these species separate in nature? Explain.

- Think back to Section 44.6. When researchers moved guppies from populations preyed on by cichlids to a habitat with killifish, the life histories of the transplanted guppies evolved. They came to resemble those of guppy populations preyed on by killifish. Males became gaudier; some scales formed larger, more colorful spots. How might a decrease in predation pressure on sexually mature fish allow this change?arrow_forwardThink back to Section 44.6.

- It's ecology, i need to draw a chart to solve this tho. Thank you! I'll leave a thumb up You are quantifying competition between two species of flour beetles. For species 1, K1 = 160 and α = 1. For species 2, K2 = 360 and b = 4. Suppose the initial population sizes are 180 of species 1 and 80 of species 2. Predict the short-term dynamics of each population and the final outcome of interspecific competition.arrow_forward6. In a coevolutionary arms race ____________.

Why did Brown’s research team create controls by completely fencing study plots and then cutting holes in their sides to allow free passage of rodents into and out of the plot? Why not just compare the density of small rodents in the large granivore removal plots with their densities in the surrounding desert? Why did they look at insectivores and what did the lack of response in insectivores indicate? Why did they repeat their large granivore experiment?arrow_forward
- Grasshopper's environment pressures: What obstacles in regard to finding food, habitat, climate, mating? How does it deal with these pressures?arrow_forwardYou are studying the competitive interactions between largemouth bass and lake trout in a several lakes. Some lakes have both largemouth bass and trout, while other lakes don’t have largemouth bass. You examined the gut content of a large sample of bass and trout. In lakes in which both species are found, 100% of the bass diet is composed of small fish while only 15% of the trout’s diet is composed of small fish. The remaining 85% of the trout diet’s is composed of zooplankton. In the lakes without bass, the diet of the lake trout is composed at 85% of small fish and 15% of zooplankton. What can you conclude from these results? Select one: a. Largemouth Bass will eventually completely exclude Lake Trout from the Lake. b. The absence of Largemouth Bass results in a trophic cascade. c. Largemouth Bass have a greater carrying capacity than Lake Trout. d. Without Largemouth Bass, the trout populations grow exponentially. e. The presence of Largemouth Bass prevents the Lake Trout to…arrow_forwardWHAT IF?
