Landscape themes - Habitat amount, amount of landcover, patch sizes and mosaics - Complexity, issues and interrelationships
3 important questions on Landscape themes - Habitat amount, amount of landcover, patch sizes and mosaics - Complexity, issues and interrelationships
Why is the species-specific version of the word habitat difficult?
1. Because habitat is multi-scaled
2. There are a lot of different methods to quantify requirements for habitats. And they may have different outcomes.
3. The habitat requirements of a certain species can differ based on lifestage, regions and vegitation types.

Why is the total amount of landcover in a certain area still important in relation to connectivity?
Because connectivity is least likely to be disturbed when the amount of a particular landcover is high.
Describe the complexities regarding thresholds
-It is difficult to identify tipping points or to predict when tipping over / regime shifts will occur.
-For some measures (eg aggregate species) there is no threshold because of opposite responses from individual species.
-For some measures (eg aggregate species) there is no threshold because of opposite responses from individual species.
