Will Matthaeus presents a case to the International Biogeography Society in Prague

In the frosty early days of January, Dr Will Matthaeus went to Prague to deliver a talk at the Ecosystem Engineering Symposium organized by Kate Lyons and Amelia Villaseñor at the 11th Biennial Conference of International Biogeography Society (IBS). In a session covering everything from Edicarian bioturbation to anthropogenic impacts and rewilding—500 million years of ecosystem engineering—Will presented plants as a foundational aspect of terrestrial ecosystems and classic examples of ecosystem and landscape reorganization with plant evolutionary changes (e.g., ‘The Devonian Plant Hypothesis’). The earliest plants were little more than ‘green slime.’  These small, prostrate organisms that were limited to wet environments may still have impacted global ecosystems by altering atmospheric oxygen concentrations.  Over the course of the evolutionary transformations that led from green slime to boreal forests and savannahs, plants have likely increased the diversity and maximum effect in their impact on ecosystems. Synthesis of paleo-plant traits, among other paleontological techniques, may provide insight into this function over periods of change, upheaval, and extinction in terrestrial environments that are informative for our future. However, understanding these changes requires expertise in a broad variety of disciplines; IBS meetings are a valuable opportunity for developing the frontiers of paleoecology through new collaborations.
