If a forest containing high species richness is fragmented by road construction, which consequence follows?

A)Decreased gene flow within populations
B)Increased core habitat area
C)Reduced edge effect influence
D)Elevated species extinction probabilities

💡 Explanation

Habitat fragmentation increases edge effects, reducing core habitat and isolating populations. Because of this, fragmented populations are more vulnerable to environmental changes and demographic stochasticity, therefore increasing the likelihood of local species extinctions, rather than promoting biodiversity.
