Concept explainers

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.

[itemD3] (refer to the photo below) What would happen to the moose population if the wolves were removed from Isle Royale?

Isle Royale National Park on a remote island was established in 1940, and designated a
wilderness area in 1976. The only mode of transportation available is by boat or seaplane.
Moose first arrived at Isle Royale around 1900. The moose population tends to increase in
years with mild winters, early spring green-up, abundant winter forage, low wolf numbers
and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from
Canada in a940. Disease has also influenced the wolf population. Between 1980 and 1982,
the wolf population declined from 50 to 14, due to canine parvovirus.

In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…

(If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?
