NEED STUDY HELP PART A Activity 1
WATCH https://www.youtube.com/watch?v=XOxsjdB4-ZQ&t=1s AND ANSWER
QUESTIONS 1. Why is genetic diversity important? Genetic diversity it occurs among
distinct populations of single species 2. Explain the connection between population size and
genetic diversity. 3. What may occur as a result of closely related individuals breeding?4.
What usually precedes extinction? Why do you think this is5. What happens to the unique
genetic diversity of a species if it goes extinct? What implications may this have for
humans?6. How is human well-being threatened by a lack of genetic diversity in our
agriculturally important crops?Activity 2 WATCH VIDEO AND ANSWER QUESTIONS
https://www.youtube.com/watch?v=nQChYlCni-s1. In the Gorilla SSP, is equal breeding
priority given to all individuals? Why or why not?2. Why was the male gorilla’s background
helpful to the SSP breeding program?3. Let’s expand on this video, and EXPLORE WESBITE

ulationsWhat does mean kinship measure?4. What does it mean for an animal to have a low
mean kinship value?5. Would an animal with a low mean kinship value be desirable for a
captive breeding program? Explain.6. Why is the potential for the loss of genetic diversity
high in captive populations of endangered species?7. What is one harmful effect of
inbreedingPART BActivity 1For this activity, you’ll go to the Encyclopedia of Earth websites
on https://editors.eol.org/eoearth/wiki/Species_diversityand
https://editors.eol.org/eoearth/wiki/Species_richness While reviewing the information on
these sites, you’ll answer the following questions 1. How does species richness influence
species diversity?2. How does species evenness influence species diversity?3. What is the
range of estimates for total species richness on Earth?4. In terms of geographic patterns,
where is species richness generally higher?5. How do disturbances affect species
richness?Activity 2For this activity, you’ll be using a simulation to quantify biodiversity at
two different time periods. The calculation for diversity indexes take into account both
species evenness and species richness. These calculations can be quite complex, so we’ve
made it easy with a handy-dandy diversity index calculator.USE THE DIVERSITY INDEX

“produce community”2. Count the number of individuals of each species that you see. Enter
this data into the column labeled “abundance” for each species in the “community 1”
section.o Note: you may not see every species listed in your community. That’s ok. You can

2. either leave abundance blank or put a 0 in the column.o Think of this like a game of i-spy.
The species may be flying in the tree tops, perched on branches, on the ground. 3. Once
you’ve documented all the species in community 1, click “produce community” again. 4.
Repeat step 4, entering this data into the “community 2” section of the excel workbook.Once
you’ve documented the richness, evenness, and diversity for the two communities, answer
the following questions in your lab notebook. 1. What is the diversity index value for
community 1? For community 2?2. Was one community more diverse than the other?3. Was
this difference due to species richness or evenness?4. Community 1 represents a
community approximately 70 years ago. Community 2 represents the same community in
the present day. Write a description (at least 7 sentences) of a scenario to explain the
difference between the two samples. Be creative in designing your scenario, taking into
account factors from the surrounding area. Think about factors that can lead to
increased/decreased/stable biodiversity. Be as detailed as possible in your
description.PART C Activity 1 WATCH VIDEO AND ANSWER QUESTIONS
https://www.youtube.com/watch?v=RFEV-hiP2gQ&t=1s1. Define biome.2. List three
different biomes. 3. What is the initial energy source for nearly all biomes?4. What two
climatic factors influence the distribution of terrestrial biomes around earth?5. If you’re
living in Southern California or South Africa, in what biome are you living?6. Rainforests and
deserts both have high temperatures, why is one so much more diverse than the
other?Activity 2GO TO WEBSITE https://www.cepf.net/our-work/biodiversity-hotspots1.
Click on the California Floristic Province (CFP)2. Answer the questions below about this
hotspotAnswer the following questions in your notebook1. What are some of the types of
ecosystems found in the California Floristic Province?2. Approximately what percentage of
vegetation remains in more of less pristine condition? Why do you think there isn’t more
left?3. Click on “species.” How does the number of native vascular plants compare to the
surrounding geographical regions?4. What percentage of CFP native plants are endemic?5.
What is it about the environment in California that has led to a large number of specialized
flora?6. While there are only 10 bird species endemic to California, why else is the CFP
important for maintaining bird biodiversity?7. What animal appears on the California flag?
Why is this animal no longer found in California?8. What type of endemic amphibians is the
CFP known for?9. Click on “threats.” What are the main threats to the biodiversity of
CFP?10. One of California’s major economic activities is agriculture. How much of the food
consumed in the US on a yearly basis is produced in California?11. What percentage of
redwood forests are left? What happened to them?12. What are the consequences of the
destruction of wetlands?13. Go back to the map. What are three other hot spots found in
other regions?DISCUSSION FORUM MUST BE 8 SENTENCES PromptLet’s say you get the
following email from a close friend:I just don’t get it. The US spent 1.5 billion dollars on
protecting threatened and endangered species in 2016 Links to an external site.. This
money is being spent when we have veterans living on the streets homeless, millions of
people without adequate health care, and so many other large scale societal issues. It seems
like the money could be spent in better ways, in ways that help humans. I don’t see the need
to protect a tiny little kangaroo rat or a frog. Why should we be using our resources to help
save these species?Construct a response to your friend that argues that protecting

3. biodiversity indeed does benefit people. Provide at least 2 articles or videos for your friend
to view that help support your argument. And make it personal, include at least 3 direct
ways in which your friend benefits from the continued existence of a biodiverse planet.
Your friend mentioned a specific dollar amount. Can you counter this argument with
another dollar amount?WATCH VIDEO
