📖 Introduction
Impact on Fauna and Gymnosperms
The Deccan Volcanism, a period of intense volcanic activity, significantly contributed to a mass extinction event. This catastrophic period led to the demise of various animal species, most notably the dinosaurs.
Beyond the faunal impact, the volcanism also caused a widespread extinction among certain plant groups, specifically gymnosperms. Their populations were severely affected, indicating a broad ecological disturbance.
Support for Angiosperms and Tropical Flora
Interestingly, despite the widespread destruction, the Deccan Volcanism did not lead to a general floral extinction. Instead, it played a crucial role in supporting a hyper-diverse tropical flora.
This volcanic activity created fertile, undisturbed habitats. These new environments proved highly beneficial for the proliferation and diversification of angiosperms, which are flowering plants.
Climatic Factors for Floral Diversity
Several environmental conditions during this period fostered the thriving of tropical flora. A prevailing warm, humid climate during the volcanic activity was a key factor.
Furthermore, the geological movement of the Indian Plate through the equator provided ideal conditions. This equatorial passage ensured consistent warmth and moisture, contributing significantly to floral diversity.
Global and Regional Implications of K-Pg Extinction
The Deccan Volcanism is recognized as a major contributing factor to the Cretaceous-Paleogene (K-Pg) mass extinction, which occurred approximately 66 million years ago. This event had profound global consequences.
Globally, the K-Pg mass extinction culminated in the widespread disappearance of groups like ammonoids (invertebrate cephalopods) and dinosaurs, reshaping the planet's biodiversity.
However, a distinct regional pattern emerged. The tropical rainforests situated on the Indian Plate demonstrated remarkable resilience. They successfully adapted to the climatic stresses and continued to thrive.
This finding highlights the higher resilience of tropical flora to significant climatic disturbances, a crucial insight for understanding ecosystem stability and recovery in UPSC environment questions (GS Paper 3).
