What is habitat fragmentation?
The process where large habitats are divided into smaller, isolated patches.
Causes of habitat fragmentation
Urban development, agriculture, logging, and road construction.
Impact on species diversity
Reduces species diversity and can lead to extinction.
True or false: Fragmentation increases genetic diversity.
False, because isolated populations often lose genetic variation.
Difference between habitat fragmentation and habitat loss
Fragmentation divides habitats; loss completely eliminates them.
What is an edge effect?
Changes in population or community structures at the boundary of two habitats.
Fill in the blank: Fragmented habitats can lead to _______ isolation.
spatial
True or false: All fragments are equally valuable to wildlife.
False, because larger and connected fragments support more species.
What is a wildlife corridor?
A natural passage that connects fragmented habitats, allowing species movement.
Effects of roads on wildlife
Increased mortality rates and reduced habitat connectivity.
What is the SLOSS debate?
Discussion on whether single large or several small reserves are more effective.
Example of a species affected by fragmentation
The Florida panther, which has limited genetic diversity due to isolation.
True or false: Fragmented habitats are less prone to invasive species.
False, because edges can promote invasion.
What is edge habitat?
The transitional area between two different habitats.
Impact of fragmentation on migratory species
Can disrupt migration routes and breeding grounds.
What is a metapopulation?
A group of spatially separated populations that interact.
True or false: Habitat fragmentation can create new habitats.
False, because it generally reduces habitat quality.
What role do humans play in habitat fragmentation?
Human activities often create barriers and alter landscapes.
Fill in the blank: Habitat fragmentation can lead to _______ stress in species.
ecological
What is landscape connectivity?
The degree to which the landscape facilitates or impedes movement.
