Question 3

spatially heterogeneous

Answer 3

area whose spatial extent varies depending on the organisms or processes of interest

Question 4

landscape is related to land use

Answer 4

composite of features and elements (fields, forests, deserts, and water bodies)

Question 5

composition

Answer 5

what and how much is present of each habitat or land cover type

Question 6

configuration

Answer 6

the spatial arrangement of those elements across the landscape; the spatial structure or path structure

Question 7

landscape structure

Answer 7

diversity and spatial arrangement of landscape elements (connectivity, human use)

Question 8

landscape function

Answer 8

interaction among those spatial elements (flow energy, nutrients, species, genes among habitat patches)

Question 9

landscape change

Answer 9

how landscape structure and function vary over time (landscapes are dynamic)

Question 10

why landscape ecology

Answer 10

• widespread ecological impact of humans
• complex ecological consequences of human land use
• understand the past and present to understand the future
