Landscape modification
6 important questions on Landscape modification
In which type of landscapes are extinction cascades most likely to occur?
- low native vegetation cover
- low landscape connectivity
- degraded native vegetation and intensive land use in modified areas, especially if keystone species or entire functional groups of species are lost.
What is landscape modification?
What are the 2 main models to view pattern-oriented view?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How do island biogeography work?
- the more species present, the less potential immigrants remaining
- dispersal ability: species not yet present on the island are probably bad dispersers
- the more species present, the larger the chance of a random extincition effect
- competition: the more species present, the more engeative competitive interactions (competitive exclusion)
What is spatial grain?
What are the edge metrics?
- Edge depth
- Nr of nearby edges
- Edge / Core ratio
