An ecologist studied how many kangaroo rats could be supported in two different habitats, a high‐quality habitat and a low‐quality habitat. The ecologist estimated the per capita benefit in each habitat, or patch, as the number of individuals increased. How many individuals must move to the high‐quality patch before an individual moves to the low‑quality patch? Find Number of individuals?

Which of the following methods will provide information to an ecologist about both the size and density of a population? a. mark and recapture b. mark and release c. quadrat d. life table
What are three ways an ecologist might capture an animal? one way an ecologist might sample a plant population in order to estimate numbers of plants?
How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? a.) Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? b.) What is carrying capacity? Do you think carrying capacity applies to people as well as to other organisms? Why or why not?
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) * Yes, this is a suitable habitat. The birth rate is higher than the death rate. No, this is not a suitable habitat. The birth rate is much lower then the death rate. 589 -358 0.155 0.845 Which of the following is true of a population approaching its carrying capacity?

Capturing and relocating is stressful for animals. In the zebra example, what are the stages of reintroduction, and what purpose does each step serve? Why is the buffalo considered a success story for reintroduction? (And -- based on what you know from lecture, what type of population growth pattern does this indicate?) Park managers use the term “adaptive management”; what do you think this means, and what are two benefits of this approach to managing ecosystems?
Mark Recapture can be written as M N = R Define each term. Use this equation to answer the following question. Show your work. A biologist for Mosaic fertilizer company catches 26 Florida scrub jays as part of their monthly environmental monitoring. Each bird is given a band. The next month, they catch 32 birds. 13 of the birds have bands. What is the estimated population size of the birds in that area?
The competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.
The diagram below shows the feeding relationships between the populations of organisms L, M, N, O, P, Q, R and S in an area. M Using only the relationships between the organisms shown in the diagram, which of the populations would have the greatest effect on the amount of available energy if it were removed? population Q O population N O population S O population L P.

An ecologist studying the size and distribution of the Karner blue butterfly is working at this level. An ecologist studying the mutualistic relationship between the Karner blue butterfly and ants is working at this level. An ecologist studying behavior of the caterpillars when they are at different larval stages is working at this level. < Previous a Choose ] [Choose ] Community Organismal Ecosystem Population ThouT [Choose ] [Choose] No new data to save.
