How do geographical barriers affect biodiversity across regions?

Geographical barriers play a crucial role in determining biodiversity by creating physical separations between populations. These barriers can lead to speciation, as isolated groups adapt to their unique environments. Here are key aspects of how geographical barriers affect biodiversity:

Key Facts

• Isolation: Geographic features can isolate species, preventing gene flow.
• Speciation: Over time, isolated species may evolve into new species, increasing biodiversity.
• Adaptation: Different environments lead to diverse adaptations among species.
• Ecosystem Diversity: Areas separated by barriers often develop distinct ecosystems.

Examples or Use Cases

• The Amazon River acts as a barrier, resulting in unique species on either side.
• The Himalayas separate species in India and Tibet, contributing to different evolutionary paths.

FAQs

• What are geographical barriers? Geographical barriers are natural features that impede the movement of species, such as mountains, rivers, and oceans.
• How do barriers influence evolution? They can lead to speciation by isolating populations, allowing them to evolve independently.
