Season 4 | Episode 10: Decoding Nature's Tiny Architects

Imagine a landscape where lichens are not just tiny patches on rocks and branches, but vibrant characters in a complex ecological story. In this episode of Geographical Thinking, we’ll talk with Miranda Frison, a master's student looking to uncover the hidden intricacies of lichen communities. Miranda’s research uses presence-only prediction and a series of environmental factors to model potential habitats where three threatened species of lichen may be found in Eastern Canada.
