Few weeks ago, Rob attended the conference Unifying Tropical Ecology: Strengthening collaborative science organised as the joint meeting of BES and gtö. Firstly, he presented our results on specialisation of pollination systems in higher elevations of Mount Cameroon. Two days later, he gave an invited talk on seasonal shifts of butterfly and moth communities along the elevational gradient of Mount Cameroon, a thesis chapter of Vincent who is still in Cameroon. Both talks brought interest of other tropical ecologists. Furthermore, Rob also made some arrangements of the 2021 meeting of the Society of Tropical Ecology which he will organise in Prague together with the Czech Society for Ecology. Last but not least, the meeting was fruitful for networking, both with old and new friends and colleagues.
