Research on Megafauna Extinction and Biodiversity in Colombian Andes
The research focuses on the extinction of megafauna, particularly large herbivores, in the Colombian Andes. The study utilized fungal spores found in prehistoric dung to establish the timing and ecological consequences of these extinctions. The researchers collected sediment samples from lakes and peat bogs and analyzed them under a microscope to identify the spores. By studying the abundance of co-profilous spores, they were able to determine the presence of large herbivores and track their decline. The study revealed two waves of extinction occurring approximately 23,000 and 11,000 years ago. The loss of megafauna had significant effects on vegetation composition and structure, leading to changes in plant diversity and increased fire activity. The findings emphasize the importance of protecting large animals and understanding the consequences of their extinction for biodiversity conservation efforts.
