Landscape ecology Flashcards
1
Q
landscape ecology
A
study of the spatial arrangement of communities at various scales
2
Q
mosaic
A
the patchwork of landcover types on a large scale, includes patches and matrix
3
Q
ecotone
A
transition zone between two communities, e.g. forest and field
4
Q
island biogeography theory
A
number of species on an island is a balance between immigration and extinction
immigration: influenced by distance from mainland (closer has more species)
extinction: influenced by size of island (larger has more species)
5
Q
disturbances
A
discrete events that disrupt community structure
intensity, scale, frequency
6
Q
intermediate disturbance hypothesis
A
medium disturbance is best for species diversity
low disturbance favors k-selected species
high disturbance favors r-selected species
