Ep. 120: Lichenology - Biodiversity and Evolution of Fungal, Algal Symbiosis (feat. Matthew Nelsen PhD)
Manage episode 326096423 series 2800606
Today on Mushroom Hour we are joined by illustrious lichen expert Matthew Nelsen PhD. Matthew is a Research Scientist at the Field Museum of Natural History in Chicago. Matt's research began in botany, ecology and environmental science and has more recently gravitated towards: (i) the evolution of symbiotic associations; and (ii) the evolution of eukaryotic microbes (fungi and algae), and the roles they have played in shaping terrestrial ecosystems and nutrient-cycling over geologic timescales. Both avenues of his research attempt to link diverse fields and organismal groups. He also has conducted work addressing the timing and evolutionary consequences of ant-plant interactions. Matt thank you so much for joining us on the Mushroom Hour!
TOPICS COVERED:
- Fungus & Algae Species Forming Lichen Partnerships
- Host Specificity in Lichen Partnerships
- Evolutionary History of Lichen
- Vascular Plants on Land Before Lichen?!
- Challenges of Working on “Big Time”
- Process of Lichen Formation, Fungal Phenotypes
- Lichen Blurring Species Boundaries
- Cleptobiosis
- Role in Carbon & Nitrogen Cycles
- Lichen as an Ecosystem
- Lichen & Air Quality in an Environment
