Textbook Question
Chapter 13, Problem 15TYK
A population of snails is preyed on by birds that break the snails open on rocks, eat the soft bodies, and leave the shells. The snails occur in both striped and unstriped forms. In one area, researchers counted both live snails and broken shells. Their data are summarized below:

The following experiment is used for the following question.
A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering
and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers, but caterpillars that hatch in
summer feed on oak leaves and look like oak twigs.
How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female
moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae
from each female were maintained in one of the four temperature and light conditions listed below.

Write a paragraph explaining how understanding population ecology relates to COVID-19 in Hawaii. You must include at least one specific example of how the data is useful (you do not need to include actual data).
Use this information to answer the following questions:
Below is a population of ornate box turtles (Terrapene ornata) which inhabit a grassland habitat. The number of turtle icons represents the relative number of turtles in each region. Ornate box turtles can have a range of shell patterns and colors, which are controlled by their genes.
New housing developments and a shopping center are constructed in the box turtles' habitat. Now the population is fragmented into three smaller populations.
Turtles in Area 2 and 3 are frequently hit by cars when they try to cross the road. Turtles with drab or dark-colored shells are more likely to be hit by cars because they are harder to see.
Turtles in Area 3 are also located near a popular outdoor recreation area. People frequently find turtles in this area and take them home to keep as pets. Turtles with more colorful patterns are more likely to be spotted and removed from the population.
How would the fragmentation of box turtle habitat…

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
- Image Source: Leigh Torres, Oregon State University Every year, gray whales migrate from feeding grounds in the Gulf of Alaska to breeding grounds off the coast of Mexico. Marine biologists are especially interested in monitoring the population of 'resident' gray whales off the Oregon Coast who skip this journey and instead spend much of the time in cooler waters. Whales have distinct markings on their flukes (i.e. tails) that can be used to identify individuals. Researchers catalog 23 unique flukes during the first week of May. During June, they resample the same area and find 39 total whales, of which 5 were already cataloged. Using the mark-recapture method, how many resident whales make up this resident population? Record your answer to the nearest whole number.arrow_forwardA population of hummingbirds feeds exclusively on nectar from orchids. Two species of orchids exist in the hummingbirds' habitat. One orchid species has long tubes to store nectar while the other has short tubes to store nectar.
