🤓 professional scientist(s) "# interested citizens 🔬a research project e.g. long-running snow goose study on Hudson Bay involved dozens of volunteer citizen scientists… including members of this 1981 banding crew

• interested citizens
• a research project…
• I HAVE ONE!
St Kilda Archipelago
St. Kilda is a UN World Heritage Site:geology, archaeology and seabirds
Evacuated in 1930 due to the isolation and squalid conditions of the small population - life was hard and unsustainable

My fungal endophyte project
Some of this grass has a microscopic fungus living inside it — a symbiont — that makes poisons to defend the grass against the sheep
“St. Brianan sheep grazed grass had higher endophyte infection, when
inspected visually.”
Lots of grasses have endophytic fungi
fungi evolved from pathogenic or disease-causing ancestors
these endophytes live entirely in the host grasses
are systemic Schardl et al. 2004. Symbioses of grasses with seedborne fungal endophytes. Ann. Rev. Plant. Biol.
Epichloë festucae - part of an evolutionary continuum
Left flower
has external, spore-producing stromata (HORIZONTAL transmission)
Right flower
regular flowers transmit fungal hyphae via the seeds, and their seedlings (VERTICAL transmission) Picture from Schardl website: http://www.ca.uky.edu/agcollege/plantpathology/schardl/schardl.htm

Endophytes make alkaloids
Ergot & other alkaloids have lethal and sub-lethal effects on the herbivores of the endophyte’s host grasses
Ref: Schardl et al’s Alkaloid-Making Fungal Symbionts essay for Plant Physiology 5th ed. Online.
Why? It’s the Ecology & Evolution of the Interaction
Are these endophytic fungi mutualists or parasites? It depends on the situation Conceptual model: Nora Saona

• 100% of tillers of Festuca rubra sampled in the field had the endophyte!
• Compared with 0-60% infection elsewhere in Wales and Mull, Scotland
When possible, I try to expand the dataset showing the presence of fungal endophytes in red fescue grass
the green line shows where we previously sampled red fescue grass
