Overview
My research focuses on the timing and ecological consequences of the late Quaternary megafaunal extinctions within the high Andean forests of Colombia. I use spores of coprophilous fungi (SCF), including Sporormiella-type, to reconstruct Late Pleistocene and Holocene megafaunal abundance. Megafauna are ecological keystone species, thus, I adopt multiproxy investigations using microfossil pollen and charcoal records to understand the potential consequences of extinction in the ecosystems they inhabited. Together, these integrated datasets can provide valuable information on the timing and ecological consequences of megafaunal extinctions in the underesearched tropics of South America.
Today, global environmental change is driving biodiversity loss and threatening contemporary fauna with extinction. This research is therefore crucial to estimate the potential repercussions of extinctions and inform management and conservation efforts.

Abstract:
The timing and ecological consequences of Pleistocene megafaunal decline in the eastern Andes of Colombia
Examining the ecological consequences of the late Quaternary megafaunal extinctions within biodiversity hotspots is crucial for our understanding of the potential consequences of contemporary extinctions. We present the first multi-species record of spores of coprophilous fungi (SCF) from Monquentiva and the high-Andean forests of Colombia to reconstruct Late Pleistocene and Holocene megafaunal abundance. Fossilised pollen and charcoal are used to examine the consequences of megafaunal declines on the surrounding vegetation and fire activity. Our SCF record indicates the presence of Pleistocene megafauna at least since 30,290 BP, with two waves of megafaunal decline at ca. 22,900 BP and 10,990 BP. At Monquentiva, megafaunal decline in the Early Holocene resulted in transitional non-analogue vegetation, loss of some herbivore-dispersed plant taxa, an encroachment of palatable and woody flora, and a rise in fire activity. Differences with other published South-American records suggest that ecological consequences of megafaunal declines were habitat-specific. Overall, we show that ecosystems in the eastern Colombian Cordillera were highly sensitive to the decline of megafaunal populations. Under the current biodiversity crisis, management and conservation efforts must account for the effects of local herbivore declines on plant dispersal, on fire activity, and the potential loss of ecosystem services.
