1. Conservation Biology
Because we love all da animals… (and plants… kind of, we just don’t act like it)

2. Why is this a thing? Because someone decided that:
more biodiversity is good for the biosphere,
extinctions caused by humans are bad,
interactions in an ecosystem are good,
and evolution is good.

3. What is biodiversity? Biodiversity Encompasses
Genetic diversity- genetic variations in a population
Ecosystem diversity- interactions in an ecosystem
Landscape diversity- landscape can have plains, mountains, and rivers, but these can be fragmented to reduce environmental interactions

4. Well so what! Direct Value Indirect Value Medicines Agriculture
Consumption
Indirect Value
Biogeographical Cycles
Waste Disposal
Freshwater
Prevention of Soil Erosion
Regulation of Climate
Ecotourism

5. Cray Cray things that happen
Habitat Loss
Rainforests
Coral Reefs
Fragmentation and Deforestation
Mangroves
Overexploitation
Exotic Invasion
Feral pigs from Europe
Kudzu from Japan
Zebra mussels

6. Pollution blah blah blah
Acid Rain will melt your face off
Eutrophication, Wat?
Ozone loss, Oh no!
Organic Chemicals, oops!
Global “dare I say it” Warming

7. How do fix it
Restoration Ecology is sub- conservation biology that seeks scientific ways to return ecosystems to a state prior to their habitat degredation

8. Because that’s what we need, a little math in our science
Hardy-Weinburg
Because that’s what we need, a little math in our science

9. Measuring Evolution (like a boss)
I wonder if things like Mutations, Gene Flow, Non random Mating, Genetic Drift, and Selection are having any effect on the population… what do I use?
If the population is not evolving, then the predicted values are the same as the experimental values. <-null hypothesis

10. Some letter combinations you will need to know
p- frequency of the dominant allele
q- frequency of the recessive allele
Formula for alleles: p+q=1
p2 –frequency of homozygous dominant
q2 -frequency of homozygous recessive
2pq- frequency of heterozygous
Formula for individuals: p2 + 2pq + q2 = 1

11. Fun Questions
There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following:
The frequency of the recessive allele.
The frequency of the dominant allele.
The frequency of heterozygous individuals.

12. more
A rather large population of Biology instructors have 396 red-sided individuals and 557 tan-sided individuals. Assume that red is totally recessive. Please calculate the following:
The allele frequencies of each allele.
The expected genotype frequencies.
The number of heterozygous individuals that you would predict to be in this population.
The expected phenotype frequencies.
Conditions happen to be really good this year for breeding and next year there are 1,245 young "potential" Biology instructors. Assuming that all of the Hardy-Weinberg conditions are met, how many of these would you expect to be red-sided and how many tan-sided?
