On Tuesday, 24 September 2025, at 18:30, Dr. Raquel Garcia will give a public lecture at the Franschhoek Theatre.

For many years, scientists have noted that species are adjusting their ranges due to climate change. To truly grasp these changes, it's important to consider more than just large-scale climate trends and examine the microclimates that animals encounter at ground level. These microclimates are affected by air temperature as well as vegetation, including invasive non-native trees. Garcia's presentation will delve into how global warming and invasive plants modify local conditions and the implications of these changes for cold-blooded animals, especially tortoises.

Garcia is a biogeographer and climate change ecologist who investigates the mechanisms behind species’ reactions to climate change. Following her experience in environmental consulting in Southern Africa, she earned a PhD in climate change biology from Copenhagen University. She has subsequently held research roles at the University of Cape Town and Stellenbosch University, focusing on how reptiles respond to microclimatic changes.

This event is included in the SmallTalX® series, which invites experts from various disciplines to Franschhoek for captivating discussions on science, nature, and culture. Each event aims to stimulate curiosity and conversation, encouraging the audience to pose questions and engage directly with the specialists.

Tickets cost R250 and cover a glass of wine, snacks, and a Q&A session with the speaker. Booking is necessary due to limited seating. Reservations can be made on the Franschhoek Theatre website at www.franschhoektheatre.co.za. For any questions, email smalltalx.info@gmail.com.
