Dr. Fabio Angeoletto is a Brazilian biologist and journalist. He holds a PhD in Ecology from the Autonomous University of Madrid, Spain. Currently he is a professor and researcher in the Graduate Program in Geography at Universidade Federal de Rondonópolis, Brazil. His research aims to understand how human factors influence the biodiversity of tropical cities, and how urban ecology could be applied in urban planning and environmental management and in the conservation of urban tropical biodiversity. Dr. Piotr Tryjanowski has been director of the Institute of Zoology at the Poznań University of Life Sciences in Poland since 2009. Currently is also guest professor at the Institute of Advanced Study Technical University of Munich, Germany. His research has a wide geographical scope, which includes tropical countries. His scientific interests include behavioral ecology, climate impact, birds in rural landscapes and urban ecology. Dr. Tryjanowski has been dedicated to studying how urbanization affects the phenology of birds, what are the impacts of urban and industrial infrastructure on birds and other animals. He published more than 250 scientific articles, which were cited more than 12,000 times. In November 2019 Professor Piotr Tryjanowski was awarded the title of Doctor Honoris Causa by the Czech University of Life Sciences in Prague. Dr.  Mark  Fellowes  is Full Professor of Zoology and Pro-Vice Chancellor at Royal Holloway, University of London. He was previously at the University of Reading, UK. With a broad background in insect evolutionary ecology, his more recent work has focused on urban ecosystems, with a particular interest in how human decisions affect urban biodiversity. His projects have taken place in the UK, Brazil, India, South Africa, Ghana, Nigeria and the USA, working on species ranging from weevils and aphids to sloth bears and leopards. In addition to his papers, Mark has published four popular science books in the 30-Second series, on Evolution, Biology, Ecology, and Zoology, the latter of which was chosen as one of the wildlife books of the year by BBC Wildlife magazine. Mark’s work has been widely covered in the press and broadcast media.
