Tylianakis Lab Group

Interested in joining our group? - Info here

Jason Tylianakis

Jason is a professor in ecology at the University of Canterbury, New Zealand (UC webpage), and Visiting Professor at Imperial College London at Silwood Park. He is the current Director of the Food Transitions 2050 Joint Postgraduate School and also a principal investigator in the Bioprotection Research Centre. His research examines how communities of interacting species respond to environmental changes. In particular, he is interested in how the architecture of interaction networks (such as food webs or pollination networks) comes to exist, and how it responds to environmental drivers. He is also interested in the conditions under which biodiversity loss has the greatest impact on ecosystem functioning and services, and in searching for win-win scenarios to balance agricultural production and conservation. In some cases, this requires knowledge of how species traits and the local environment jointly shape the structure of interaction networks, and how this structure affects processes at the entire community level. He addresses these questions using a variety of systems (plants, insect herbivores, parasitoid-host systems, plant-mycorrhizal associations) and approaches (field observations, field and lab experiments, meta-analysis). Our group meets jointly with Daniel Stouffer's lab group at UC.

Postdocs

warwick allen

Warwick recently completed his PhD at Louisiana State University where he examined the role of plant genetics and plasticity, biogeography, and species interactions in driving plant invasions at large spatial scales. His postdoctoral research will investigate how the structure of multitrophic species interaction networks can influence the success of invasive plants and arthropods, and how native communities respond to these invasions. He is located within the Bioprotection Centre at Lincoln.
Contact email warwick.allen[at]canterbury.ac.nz. Warwick also had a 'big year' of birding in 2019 - check out his instagram of native New Zealand birds here.
