Endangered Species Lab
1.
Include two photos or one video (no more than two minutes in
length) illustrating the organism in its natural setting. Do not use any
material showing harm to this organism.
2.
State this organism’s ecosystem role. See pages 95 to 98 in your
textbook. Every organism has an ecological value because they play an
important role in the chemical cycling and energy flow. Since the Grey wolf
contributes to other animals in its area along with the plant life, if it went
extinct the other organism’s it helps would be affected largely.
3.
State at least two ecological services this organism
provides for humans and other species (at least two ecological services for
each, humans and other species = four total), besides providing food. initiating
trophic cascades that result in increased growth of woody riparian plants, in
nesting sites for songbirds, in materials for beaver dams and in cool, deep
ponds needed by juvenile fish. They also help with tourism in the region they
live in. People want to see them so they will stay in the town close by and
spend money, which helps local economy.
4.
Include a chart or graph showing population of this organism
over time and interpret in words the information there.
The chart shows how the
population of the grey wolf was so low in 1979, and in 1986 they believed that
only 15-20 wolves still remained. Thanks to many different organizations the
Grey wolves are making a come back as you can see from the chart. There was
even one spotted near the Grand Canyon last year!
5.
Referring to Figure 9-3 in your textbook, list the
characteristic(s) that endanger(s) your species. Low reproductive rate: Because there are so little Grey Wolves left
they do not have high reproductive rates. Specialized niche, Feed at high
trophic level.
6. Determine if this
organism is affected by density dependent and/or density independent factors.
Explain this. Independent such as natural disasters, means that no matter how
large or small the population is the population will still get affected such
as cold weather, tornado, fire. Dependent are factors that depend on how
large or small the population is these include food, water, and place to live.
7.
Name and give a two or three-sentence description of an individual
or group who is a champions of this species. For the Grey wolf the U.S. Fish and Wildlife Service is the greatest
champion. They have gone above and beyond to make sure that the Grey wolf does
not go extinct.
8.
Include a link to one recent scientific article or story about
this organism that was written or produced in the last year. Suggestions for
sources include ScienceNews, ScienceDaily, and NPR. Provide a two or three-sentence summary of
each. A panel of
scientists gathered to discuss the possibility of delisting the Grey wolf from
the Endangered Species list. They talked about how they needed to do further
research before making the final decision to remove or not to remove the Grey
Wolf’s from the list.
9.
