APFIVE Habitat Fragmentation and Genetic Diversity
In a forest fragmented by logging, habitat patches are separated by 500-meter strips of cleared land. A study conducted ten years after fragmentation finds that tree species with wind-dispersed seeds have higher genetic diversity than species with animal-dispersed seeds. Which of the following best explains this observation?
A
Higher reproductive rates in wind-dispersed species
B
Preferential predation on wind-dispersed seeds
C
Increased mutation rates in animal-dispersed species
D
Disruption of animal movement corridors between fragments
