Habitat Loss and Fragmentation
Captions available
The idea
Habitat loss removes usable area outright; fragmentation breaks remaining habitat into isolated patches, both reducing carrying capacity, per Bio 3559, and a population's ability to persist.
In practice
A forest cleared into scattered patches supports a smaller effective population than the same area left continuous.
Where people slip
Fragmentation harms a population beyond area loss, since isolated patches also block movement and gene flow continuous habitat allows.
