During the last three years, she treated her plots by insecticides, fungicides and manipulated access of large mammals or predators tot he plots. Today, I was invited also to see and assists and become a feeder for billion of mosquitoes. We helped Marketa to collect the biomass, locate all saplings which she was marking throughout the experiment.
