You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200
Vsevolod [243]

Answer:

Option A 400 individuals

Explanation:

Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.

N = (MxC) / R

Where N = estimated Number of individuals in the population

M = number of individuals captured and Marked = 200

C = total number Captured the second time (with and without a mark) = 200 and

R= number of individuals Recaptured (those with a mark) = 100

Thus, we have

N = (MxC) / R

= (200 x 200) / 100

= (40,000) / 100

= 400 individuals.

Which method involves breeding animals in a controlled environment? a. inbreeding b. captive breeding c. outbreeding d. crossbre
zhannawk [14.2K]

The answer is captive breeding.

Captive breeding involves breeding animals in a controlled environment.

What is captive breeding?

The technique of keeping plants or animals in confined spaces, such as zoos, botanical gardens, and other conservation facilities, is known as captive breeding, sometimes known as captive propagation. It is occasionally used to support species that are under threat from human activities including climate change, habitat loss, fragmentation, excessive fishing or hunting, pollution, predation, illness, and parasitism.

Relatively little is known about the circumstances necessary for effective breeding in many species. The success of a captive breeding program may depend on knowledge of a species' reproductive biology. Captive breeding programs have the potential to preserve some species from extinction, but they depend on a variety of criteria, including genetic, ecological, behavioral, and ethical considerations.

lesya [120]

Even though New Zealand has a smaller population than Australia, it has a greater population density because it covers a much smaller area. Australia’s population is approximately five times larger than New Zealand’s while the area Australia covers is approximately 30 times larger than the area New Zealand covers.
