Question 1

What is threatening the coral reefs in the Florida Keys?

Answer 1

Heat
Nutrient Pollution
Stoney Coral Tissue Loss Disease (SCTLD)

Question 2

Conservation Biology is sometimes called a crisis science, how does this relate to extinctions?

Answer 2

They attempt to stop/slow extinctions and conserve the species we have

Question 3

What is Anthropocene?

Answer 3

Denoting our current geological age

Question 4

Other than extinction, what signs suggest population of wildlife are in trouble?

Answer 4

Extirpations
Biotic Homogenization
Pop. Decay
Mass mortality events
Genetic variation

Question 5

Extirpations

Answer 5

Local extinctions i.e, wolves in Yellowstone

Question 6

Biotic Homogenization

Answer 6

Species are becoming more alike, i.e, invasive species, ecological communities becoming more alike

Question 7

Population Decay

Answer 7

The decrease of a species population size, i.e, grey wolves

Question 8

Mass Mortality events

Answer 8

Extreme population decay, can be caused by overhunting, deforestation, climate change, etc.

Question 9

Genetic Variation-Heterozygosity

Answer 9

Different alleles, i.e moths of the same species with different colors.

Question 10

What is carrying capacity and how might this concept relate to humans and our population growth?

Answer 10

How many organisms an ecosystem can comfortably maintain, we are probably hitting our K

Question 11

How has human population grown in the past?

Answer 11

Was slight at first, then started to increase exponentially

Question 12

When was human growth rate the highest?

Answer 12

About 1960

Question 13

How big is the human population expected to get?

Answer 13

around 11 bill

Question 14

What is the human population size and growth rate now?

Answer 14

About 8 bill with less than a 1% growth rate.

Question 15

What is expected for the future of the human population?

Answer 15

Hit K and level off/ decrease in population.

Question 16

How does the human growth rate compare before and after its completed?

Answer 16

More level at first, then increases

Question 17

As a demographic transition starts, what changes first?

Answer 17

Death rate

Question 18

How is the human growth rate expected to change in the future? What from?

Answer 18

Expected to level out, from declining birth rates

Question 19

Population growth in the US is slow, why should we worry about resource use?

Answer 19

Because it is still at a steady incline

Question 20

How does conservation biology differ from disciplines such as population genetics, taxonomy, and biogeography? How about forestry?

Answer 20

Conservation: About biodiversity and data

Forestry: Applied science, resource management.

Question 21

What are the major goals of conservation biologists?

Answer 21

-Document diversity on the planet
-Investigate human impact on species, communities and ecosystems
-Develop practical approaches to prevent the extinction of species in the ecosystem

Question 22

Preservationist Conservation viewpoint

Answer 22

-Needs of art should outweigh the needs of society
-John Muir
-Activists

Question 23

Resource Conservation viewpoint

Answer 23

-Natural resources exist for benefit, but should be regulated
-Gifford Pinchot
-Fisheries

Question 24

Evolutionary Conservation viewpoint

Answer 24

-Nature is a system of interrelated processes. All organisms are needed to maintain itself
-Aldo Leopold
-Conservation Biology
