Textbook Question
Chapter 16, Problem 1GFO
What species are endangered in the region where you live or go to school? Choose one of these species and determine what factors, such as loss of habitat or overhunting, have contributed to its population decline. What actions are being taken to protect this species from extinction? What, if anything, is being done to help the population recover?

A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers)
a) Yes, this is a suitable habitat. The birth rate is higher than the death rate.
b) No, this is not a suitable habitat. The birth rate is much lower than the death rate.
c) 589
d) -358
e) 0.155
f) 0.845
What do restocking programs for wild animals involve?
Pick the correct following statement number:
1. Releasing individuals into an existing population to increase the size of the population and the diversity of its gene pool
2. Releasing wild-collected individuals into a new site
3. Releasing captive-bred individuals into a new site
4. Releasing captive-bred or wild-collected individuals into an ecologically suitable site within their historical ranges where the species no longer occurs
You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America.
Which of the following could be a possible factor for the increase in the grizzly population?
Loss of habitat
Reduction of resources
Increased industrialization
Higher birth rate over death rate

- You are a population ecologist studying animals in a national park, and park managers are asking for advice on how to focus their limited conservation funds. How would you rate the following three species, from most vulnerable (and thus most in need of conservation attention) to least vulnerable? Give reasons for your choices. • A bird that is a generalist in its use of habitats and resources • A salamander endemic to the park that lives in highelevation forest • A fish that specializes on a few types of invertebrate prey and has a large population sizearrow_forwardhttps://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step. 6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of thesearrow_forwardWhich of the following best predicts the consequences of introducing brown rats ( invasive species) to an island where they did not previously exist? Choose 1 answer: Choose 1 answer: (Choice A) A The rat population size will likely remain small, and as a result the rats will not be able to outcompete other organisms for resources. (Choice B) B Without its typical food sources, the rat population will not be able to become established, and the island ecosystem will remain stable. (Choice C) The rat population will grow rapidly, disrupting the island's community structure by feeding on native plants and animals. (Choice D) D Without any natural predators, the rat population will become established and help increase the species diversity of the island answer explainarrow_forward
- What species is targeted for conservation? What are their primary social behaviors (Group size, lifestyle, foraging habits and diet, hierarchies, territorial habits)? Where are they located and what are potential human influences on their habitats? What are the specific conservation strategies proposed in the report? How do they make use of new technologies (like GPS tracking, drone survey etc if applicable)? Do you think the strategies are appropriate given the particular social behaviors of that species? Do the strategies appropriately address the needs of this species as well as local community well-being and the political context?arrow_forwardWhat are the implications of the "bottleneck effect" for wildlife managers who try to help endangered species, such as the whooping crane, recover from near extinction?arrow_forwardIn 2010, 150 coyotes (Canis latrans) were counted in Pierce County, WA. And the growth rate is 14 coyortes per year. Following a survey of the community, the social carrying capacity of coyotes was around 500 individuals. How long will it take for the coyote population to reach this human tolerance goal? Biologists have estimated the biological carrying capacity for coyotes in the county to be 1000 individuals. How long will it be before the population reaches carrying capacity using exponential growth? Would it take more or less time for the population to reach carrying capacity if using logistic growth equation and assumptions?arrow_forward
- You are observing two different species of caterpillars feeding on green shrubs in the Sacramento Mountains. One has bright red and yellow stripes, the other is a nondescript greenish color. You hypothesize that the two species have adopted different antipredation strategies. 1) What would these two strategies be called? 2) Which species would you predict is noxious to potential predators and which species is palatable? 3) Which species would you predict would alter its behavior more in the presence of predators?
