Tropical Ecology

Tropical Ecology is a specialized field that examines the intricate relationships between organisms and their environment within the Earth's tropical zones, the region between the Tropics of Cancer and Capricorn. This discipline focuses on understanding the structure, function, and immense biodiversity of ecosystems such as rainforests, savannas, and coral reefs, which are characterized by high levels of solar radiation, warm temperatures, and distinct precipitation patterns. A critical component of tropical ecology is its strong link to conservation, as it seeks to address the significant threats posed by deforestation, climate change, and other human activities to these globally important and highly sensitive biomes.
