Impact of Temperature on Tropical Forest Species

Recent studies have brought into light the vulnerability of tropical forest and agroforestry species to rising temperatures in the Western Ghats. Researchers have monitored various species to understand their thermal limits and response to extreme heat. This research is essential for predicting the future of these ecosystems under climate change.

Thermal Tolerance and Leaf Damage

Scientists observed 13 agroforestry and four native species in Karnataka. They measured leaf temperatures, finding that some exceeded critical thresholds for photosynthesis. The parameter T₅₀ indicates the temperature at which photosynthetic efficiency declines by half. Exceeding this threshold can lead to irreversible cellular damage. Many species experienced brief spikes in temperature, which may not always result in permanent injury.

Effects on Agroforestry Species

Among the agroforestry species studied were cardamom, coffee, and cocoa. Some experienced damaging temperatures for short durations. Despite this, the brief exposure is typically insufficient to cause irreversible harm. However, the potential for future climate scenarios raises concerns about their long-term viability.

Slope Aspect

Researchers also explored the influence of slope aspect on tree cover in the Western Ghats. They found that north-facing slopes had denser tree cover than south-facing slopes. This asymmetry is linked to differential heating and moisture retention. The study confirmed that slope aspect impacts local vegetation distribution.

Implications for Biodiversity Conservation

The findings suggest that slope aspect should guide biodiversity conservation and afforestation efforts. Understanding the relationship between slope orientation and vegetation can help in planning effective restoration projects. It is crucial to consider these factors to enhance the success of conservation initiatives.

Future Research Directions

Further studies are needed to validate these findings in diverse ecological contexts. Ground-truthing the data will provide vital information about species-specific responses to temperature and slope aspect. This will aid in developing strategies for managing and restoring tropical forest ecosystems.
