From diatoms to DNA: lakes as sentinels of global change

IAS Visiting Fellow Dr Adam Heathcote delivers a seminar on their research - 

Although lakes make up a relatively small proportion of the Earth' surface, they are optimally situated in the landscape to serve as sentinels of natural and human-induced global change.  Lakes sit at the base of terrestrial catchments and integrate information which flows into them through stream networks or is deposited from the atmosphere. Using a variety of biological and geochemical proxies, we can use lakes to reconstruct everything from the historic and ongoing impacts of anthropogenic eutrophication to the effects of an increasingly warm planet.  I will share a few examples of classical (i.e., geochemistry, diatoms, algal pigments) and new (sediment DNA) techniques of using lake sediment archives to reconstruct environmental history and predict how these ecosystems may respond in the future.

Arrivals from 11:45 am for a 12:00 noon start. For those joining in-person, lunch will be served after the seminar from 1:00pm.

This event is hybrid format, please use the required booking button at the bottom of the page to choose either in-person or online attendance.

By booking a place at this event, attendees agree to behave in a respectful manner such that everyone feels comfortable contributing as they wish. The IAS reserves the right to eject anyone who does not abide by this policy.

IAS seminars are typically recorded, minus any Q&A sessions at the end, again to encourage contributions. The recordings are then uploaded to our website on a Fellows bio page and/or Programme page, along with our IAS YouTube Channel. If you are not able to attend a seminar live, please do still register as we will email everyone who registered to let them know once the recordings are made available.
