Conservation Biology - Exam 1

Question 1

values associated with the inherent worth of an object or quality

Answer 1

intrinsic values

Question 2

the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and ecosystems

Answer 2

biodiversity

Question 3

based on how biologically unique and area is and how severe the threat posed by development is

Answer 3

hot spot

Question 4

whether a species is exclusive to one area or not

Answer 4

endemism

Question 5

parts of an ecosystem that make less room for species to live, grow, and succeed

Answer 5

edge habitats

Question 6

cutting out only trees that are wanted/needed, invasive species, or easiest to cut

Answer 6

selective cutting

Question 7

many desirable wildlife species have healthier populations if clearings are provided

Answer 7

wildlife clearings

Question 8

remove all but the largest, most desirable trees, the remaining trees provide seed, rain, and shade for new young trees

Answer 8

shelterwood cut

Question 9

removes ALL trees from the forest - can be done in patches, strips, or whole forests

Answer 9

clearcutting

Question 10

taking only the trees that are favorable

Answer 10

highgrading

Question 11

hunting, fishing, harvesting, or collecting at a rate that outstrips the species’ ability to reproduce

Answer 11

overexploitation

Question 12

the number of organisms of a species that the habitat can support

Answer 12

carrying capacity

Question 13

any non-domesticated animal hunted for food or for sport

Answer 13

game

Question 14

game hunted in Central Africa

Answer 14

bushmeat

Question 15

incorporation of genes from one species into another species

Answer 15

introgression

Question 16

resources that are not owned by one person/place are overexploited because of public access - thus the system crashes and effects people/the ecosystem

Answer 16

tragedy of the commons

Question 17

males aggregate in large groups to attract females

Answer 17

lek

Question 18

random process that causes the frequency of a gene variant, or allele, to change a population over time

Answer 18

genetic drift

Question 19

synergistic interactions among mutation, population size, and genetic drift

Answer 19

mutational meltdown

Question 20

accumulation of deleterious recessives

Answer 20

genetic load

Question 21

evolved there and from there

Answer 21

native

Question 22

did not develop there

Answer 22

non-native

Question 23

nonnative species that has been there so long that it has accepted a place in the ecosystem

Answer 23

naturalized

Question 24

plants that have a negative impact/we don’t want them

Answer 24

noxious weeds

Question 25

nonnative species that take resources and space from native species - has detrimental effects - does not have any effective predators so they spread rapidly

Answer 25

invasive species

Question 26

Answer 26

easements

Question 27

symbiotic bacteria in legumes
