The decline in bird populations in tropics due to climate change , Pg8

Key Highlights:

• Bird populations in the tropics have decreased by approximately 25-38% since 1980.
• The decline is attributed to intensifying heat extremes associated with climate change.
• Some bird species have experienced declines exceeding 50%.

Detailed Insights:

• Tropical regions are particularly vulnerable to climate change impacts due to their high biodiversity and sensitivity to temperature fluctuations.
• Habitat loss, deforestation, and agricultural expansion exacerbate the effects of climate change on bird populations in the tropics.
• Declining bird populations can disrupt ecosystem functions, such as pollination and seed dispersal, impacting overall biodiversity and ecosystem health.

Scientific/Technical Concepts Involved:

• Climate Change: Long-term shifts in temperature and weather patterns, primarily caused by human activities.
• Heat Extremes: Periods of unusually hot weather that can have significant impacts on ecosystems and human health.
• Ecosystem: A community of living organisms interacting with each other and their physical environment.
