PhD student in the School of Geography at the University of Nottingham. Researching the prediction of sediment transport dynamics in rivers infested with invasive signal crayfish.

BES Festival of Ecology 2020

Date:

The British Ecological Society’s Festival of Ecology 2020 was the first conference I presented at as a PhD student. Due to the COVID-19 pandemic, the conference was held online. The poster I presented provides an outline of my proposed research, splitting my methods into three key components.

Below are the details of the poster I presented, including the videos to which I linked on the poster.

Charlotte E. Vinera, Matthew F. Johnsona and Nicholas Doddb

Presented at the British Ecological Society Festival of Ecology, 14-18 December 2020
