Ecology Final

Front 1

Conservation Biology

Back 1

scientific stuy of phenomena tht affect the miantainence, loss, and restoriation of biodiversity

Front 2

ecosystem services

Back 2

processes that sustain human life such as water purification, pollination of craps

Front 3

extinction vortex

Back 3

the pattern of a population dropping below a certain size and becoming vulnerable to processes that act to reduce it even further

Front 4

taxonomic homogenization

Back 4

spreading of introduced species and native generalists reduce local specialist reducing biodiversity

Front 5

habitat degradation

Back 5

changes that reduce the quality of the habitat for many, but not all, species

Front 6

habitat fragmentation

Back 6

the breaking up of once continuous habitat into a complex matrix of habitat patches

Front 7

habitat loss

Back 7

outright conversion of ecosystem to another use

Front 8

invasive species

Back 8

non-native introduced species that sustain growing populations and have large effects on communities =

Front 9

fine-filter

Back 9

the emphasis on protecting species over protecting their environment

Front 10

coarse-filter

Back 10

emphasis on protecting habitats over protecting species

Front 11

evolutionaryily significant units

Back 11

units used as appropriate targets of management within species

Front 12

population viabilityy analysis

Back 12

the potential future status of a population of interest

Front 13

surrogate species

Back 13

species whose conservation will serve to protect many other species with overlapping habitat requirements

Front 14

flagship species

Back 14

species that help you get public support (pannda)

Front 15

Umbrella species

Back 15

species who if we protect their habitat it protects many others (generally large animals with large area needs)

Front 16

focal species

Back 16

species you choose to protect because they are all so different, cast a wide net of protetion

Front 17

landscape ecology

Back 17

emphasizes the causes and consequences of spatial variation across a range of scales

Front 18

landscape

Back 18

an area in which at least one element is spatially heterogenous (varies from one place to another)

Front 19

mosaic

Back 19

term used to describe heterogeneous landscapes

Front 20

landscape compostiionn

Back 20

the kinds of elements or patches in a landscape, as well as how much is present

Front 21

landscape structure

Back 21

physical configuration of the different compositional elements

Front 22

edge effects

Back 22

the diverse changes that occur on the boundaries of habitats

Front 23

core natural areas

Back 23

areas where the conservation of biodiversity and ecologucal integrity takes precedence over other values or uses

Front 24

biological reserves

Back 24

small reserves with conservation of single species in mind

Front 25

buffer zones

Back 25

areas that augment protection of protected areas, are large areas that are partially compatible with mamy species' resource requirements

Front 26

habitat corridors

Back 26

linear patches that connect blocksof habitat (connect populations that are isolated)

Front 27

ecosystem management

Back 27

driven by explicit goalls, executed by policy, and made adptable by monitoring and research based on our best understanding of ecological interactions

Front 28

adaptive management

Back 28

adjusting to policies as needed

Front 29

anthropegenic

Back 29

human associated

Front 30

land use change

Back 30

clearing of forest and burning of fossil fuels that releases C

Front 31

Climate change

Back 31

directional change in climate over several decades

Front 32

greenhouse gases

Back 32

water vapor, CO2, CH4, N20

Front 33

acid neutralizing capacity

Back 33

ability of ecosystems to adapt to acidity
