Flashcards in Unit 1 Deck (47):
1

Passive management

Habitat restoration to support the need of an endangered species, or promote a predator of an invasive species

2

Active management

captive breeding programs, incubation turtle eggs collected from the beach

3

invasive species

not historically there
(zebra mussels, yellow iris, kudzu and many more )

4

endangered species

species with low count, threatened to extinction
*(grey wolf, poison dart frogs, rhino, cheetah)

5

anthrocentric

human uses are right and superior to the natural world
nature is tool/resources

6

Biocentric

living organisms (megafauna - bigger organisms)
single species approach to conservation and education

7

ecocentric

broad view (living + non-living)
approach to organisms and their environment based on function

8

biotic

general term used to describe living things

9

abiotic

general term used to describe non-living things (aquatic, aerial, and terrestrial systems)

10

indirect evidence

most common strategy for searching life in remote area on this planet

11

most of the classification for organisms on the tree of life are

single cellular

12

asexual population like bacteria have high [blank] yet low [blank] due to cellular division

abundance
diversity

13

Nature's Tool Box is

a supply of diverse genes that may lead to population fitness based on different selective pressures

14

invasive species are [blank] which make them successful in occupying new habitat

generalists

15

macroevolution

events impacting populations over long periods of time

16

microevolution

change in genetic sequences

17

allopatric speciation

event that split/separate specie geographically

18

bottleneck

loss in genetic diversity in population due to pressure events

19

what would be considered alive?

reproduction
consume energy/obtain energy
growth
homeostasis

20

cells are

building blocks of life
key for homeostasis
different patterns/forms
define boundaries

21

species

a population who can interbreed and create fertile offspring

22

diversity

variety of life of earth at all levels
*counting the number of species*

23

abundance

how many of each species
*counting how many organisms in a specie*

24

extinct

species is no longer living/existing

25

natural selection

happen in a population (affecting genes)
survival of the fittest
selection by nature

26

descendant with modification

heritable genes are passed down over time

27

fitness

the ability to reproduce in relative to other members of the population

28

microevolution

affect population
causes:
-mutation
-gene flow
-non random meeting
-genetic drift

29

genetic mutation

change in genetic sequences (provide variation)

30

gene flow

gene migration
(when organisms move from one place to another and reproduce, passing genes on)

31

non random mating

selection of mate according to pheno/genotype
(very selective)

32

genetic drift

gene slowly leaving the population

33

bottleneck

gene pool getting smaller

34

founder effect

a small population in a greater population

35

macroevolution

large changes over long period of time
creating a new specie

36

asexual mating

cloning of oneself to create new individuals

37

sympatric speciation

when a new specie form from another and cannot reproduce due to preferences (ex. food)

38

reproductive isolation

reproductive barriers

39

zygote

fertilized egg

40

prezygotic barrier

barrier before the zygote

41

postzygostic barriers

barriers after zygote

42

ecological barriers

geological barriers

43

temporal isolation

time barriers

44

behavioral isolation

different mating ritual

45

mechanical isolation

lock-key mechanism
when genitals are not compatible

46

genetic isolation

sperm cannot fertilize the egg

47

gamete

sex cell
