Summary Introduction

To investigate:

The two wolf populations in Alaska and northern Great Lakes can be considered different species. The information required to examine this.

Introduction:

When the environment creates an outside barrier to reproduction, such as a mountain range or river, it is known as reproductive isolation. A genealogical species can be defined as a base group of organisms whose members are associated more closely to each other than to outside organisms. These do not contain any outside group.

The current wild population is estimated to be about 50 individuals. However, a new threat to red wolves has arisen: hybridization with coyotes (Canis latrans), which have become more numerous in the areas inhabited by red wolves. Although red wolves and coyotes differ in morphology and DNA, they are capable of interbreeding and producing fertile offspring. Social behavior is the main reproductive barrier between the species and is more easily overcome when same-species mates are rare. For this reason, some people think that the endangered status of the red wolf should be withdrawn and resources should not be spent to protect what is not a “pure” species.
Conservation biologists working with the Florida panther have set out camera traps to estimate the overall population. Through a combination of live trapping and hair snares, the biologists have worked out the exact genetics for two alleles in all remaining individuals. The homozygous recessive state causes a debilitating disease and the panthers die before reproducing. Biologists have found a high incidence of heterozygous individuals. Help the biologists determine the best conservation action in order to protect and boost the genetic health of the remaining population.   The current population of Florida panthers in this example is twenty which is based upon available habitat.  Eighteen of the panthers are heterozygous [Aa].  Scientists have determined that eighteen is the minimum viable population for the Florida panthers. How many of the twenty panthers in this generation will suffer from the disease and die?  What is the number of survivable Florida panthers?
When wolves were returned to Yellowstone National Park in 1995, some of the effects noted were increasing levels of berries available to black bears, stabilization of stream banks, increased nesting habitat for birds, and increasing beaver numbers as a result of rejuvenating aspen trees. These were later determined to be the results of reduced numbers and altered feeding behavior of elk as they were preyed upon by the wolves. Given this information, which of the following best describes wolves in Yellowstone National Park? A. They are a primary consumer B. They are an ecosystem engineer C. They are a foundation species D. They are a keystone species E. They are a flagship species
