Question 1

what is the trend with birds we see in urban areas?

Answer 1

migrant species are more sensitive to urban areas both near and far from forest patches.

Question 2

what is the trend with birds we see with less intense agriculture?

Answer 2

may soften or reduces edges decreasing edge species richness.

Question 3

what is the trend with birds in intense agriculture?

Answer 3

on a broad scale decreases total species abundance in patches but edge and resident species benefit.

Question 4

between agriculture and peri-urba what is worse for the birds?

Answer 4

peri-urban.

Question 5

the ——- of birds are really what decides how birds will respond to different landscapes.

Answer 5

traits. Species that had decreased abundance in human-dominated matrixes compared to forested matrixes exhibited different traits compared to those species that did not change or increase in abundance.

Answer 6

1. dispersal
2. resource provision
3. abiotic environment.

Question 7

what are 5 modifying dimensions for the matrix to patch relatonships?

Answer 7

1. spatial variation
2. spatial scale
3. temporal variation
4. temporal scale
5. adaptation and plasticity
