This week we are hosting Trevor Keenan from Macquarie University in Australia (link to his home page). He´s been collarborating with our work group for several years already, and published some rather well-known papers together with members of our lab. The most recent one being the Tansley review about the variation patterns of photosynthesis in plant canopies that help to predict climate change (link to blog post) (link to full text). His purpose of visiting is indeed compiling a follow-up paper on this Tansley review together with Ülo. Good luck to them with staying indoors with such weather!
