I’m in Cusco, Peru for our TraitTrain course were we teach students about functional leaf traits, climate change ecology and more. Today we were  shopping material for the course in Cusco, an adventure! And now you’ll think we bought colourful fabric, an Alpaca, some Inka souvenirs… No, we got pvc tubes, metal poles, 5000 envelopes, plastic bags, measuring tape, etc.
