Timm Dobert (2018). Timm completed his PhD entitled “The influence of logging on understorey plant communities in tropical lowland rainforest in Borneo” in 2015 with the School of Animal Biology at the University of Western Australia and with CSIRO Land and Water. Timm was supervised by Raphael Didham, Bruce Webber and Katharine Dickinson and his research was conducted as part of the Stability of Altered Forest Ecosystems (SAFE) project in Sabah. Timm examined the level of exotic plant invasions and variation in functional traits and evolutionary relatedness across a logging-intensity gradient from primary to repeatedly logged forests. His results showed that logging facilitates the invasion of exotic plants, albeit at currently low levels, and that a strong logging signal persists in the functional and phylogenetic structure of understorey plant communities. These findings emphasise the complexity of logging-induced impacts, over and above species diversity, with significant implications for conservation management of modified tropical landscapes. After his PhD, Timm worked with us as a Volunteer Fellow, during which time he continued to develop his research interests on the impacts of fragmentation and global change on tropical forest biodiversity.
