Today was all about looking at whether there are any differences between the endemic and invasive plants that give the invasives some sort of advantage. Field measurements included chlorophyll fluorescence using a PEA (photosynthetic efficiency analysis) meter, leaf thickness and we also took leaf impressions (using a dental product) to look at stomatal density in the lab tomorrow.

Further down the volcano, at Caldeira Velha, a different selection of plants provided further data while the "thermal" pool allowed a surprisingly cold swim!

Every day we are seeing what seem like familiar species but most of them are endemic species or subspecies and look a little different:
|"Atlantis" (Azorean) Herring Gull|
|Sao Miguel Grayling (Hipparchia miguelensis)|
On the way back to the university for food, several of the staff made a detour to the coast for a fruitless search for an endemic water beetle in the pools in the splash zone. Maybe next year...
