Question 1

Figure 52.14 
-Looking at the data in the figure above from the hare/lynx experiment,what conclusion can you draw?

Accepted Answer

The hare population is influenced by both predation from lynx and the availability of food, as these are common factors affecting prey populations in predator-prey dynamics.

Question 3

Based on the information in the abstract,which of the following statements is the most correct?

Accepted Answer

According to the abstract, the long-term contribution of a fragment to colonization events in the network is one of the measures of fragment value, and it is comparable to density-dependent measures in general matrix population theory. The abstract suggests that the value of a fragment increases if it has a higher long-term contribution to colonization events, which means that the metapopulation would have more fragments. Therefore, choice C is the most correct.

Question 4

One measure for the value of the patch was given by the long-term contribution of a fragment to colonization events in the network.How do the properties of a landscape and the properties of a species affect the value of a patch?

Accepted Answer

The value of a patch depends on both the properties of the landscape and the properties of the species. The landscape properties, such as the size and connectivity of patches, can affect the ability of a species to disperse and colonize. The properties of the species, such as its habitat requirements and dispersal ability, can affect its ability to use a patch as a habitat and its likelihood of colonizing other patches in the network. Therefore, both landscape and species properties are important factors in determining the value of a patch.

Question 5

What is Earth's carrying capacity?

Accepted Answer

Earth's carrying capacity is not a fixed number as it depends on various factors such as resource availability, technology, and lifestyle choices. It is influenced by human decisions and actions, making it a flexible concept rather than a fixed number. Therefore, option D, "Earth's carrying capacity is what we decide it will be" is the best choice.

Question 6

A model that estimates the likelihood that a population will avoid extinction for a given period of time is called a(n)

Accepted Answer

A population viability analysis is a model that estimates the likelihood that a population will avoid extinction for a given period of time. Metapopulation refers to a group of interconnected populations of the same species. An age pyramid is a graphical representation of the age and sex distribution of a population. A life table is a statistical tool used to summarize the survival and reproductive patterns of a population.

Question 7

Figure 52.15 
-Looking at the figure above,what is contributing significantly to stabilizing population size over time?

Accepted Answer

High migration can contribute to stabilizing population size by balancing out birth and death rates, leading to a more stable population over time.

Question 8

Which of the following statements regarding the future of populations in developing countries is FALSE?

Accepted Answer

The statement that fecundity is predicted to increase is false. In fact, many developing countries are experiencing a decline in fertility rates due to increased access to family planning and education, as well as changing social norms.

Question 9

In 1987,there were only 22 condors (birds)in the wild because of habitat destruction ;all were brought to zoos and breeding centres for captive breeding.In 1991,the first condors were re-introduced into the wild.To determine if the population of wild California condors is increasing,which methods would best be suited to gathering condor population size/density information?

Accepted Answer

The answer of In 1987,there were only 22 condors (birds)in...
