transition regions (edges) of two biological communities

Question 11

landscape structure influences

Answer 11

flow of organism

Question 12

metapopulation

Answer 12

population of many species occur in spatially isolated patches with significant exchange in individuals

Question 13

case study: habitat patch size, isolation, and density of butterfly population

Answer 13

butterfly density affected by size and isolation of habitat patches.
isolated patches had lower density
population is partially maintained by immigration

Question 14

habitat corridors

Answer 14

connect habitat fragments can mitigate effects of habitat fragmentation.
promote movement

Question 15

case study: had dad and Baum

Answer 15

corridors influence movement of butterflies associated w/ early successional habitats
more likely to find habitat patches along corridors
