International workshop on fossil chironomids in Basel, Switzerland

Fossil chironomids from the Pleistocene to the Anthropocene

Organizer: Oliver Heiri, University of Basel, Switzerland / Supporting team: Colin Courtney-Mustaphi, Ilona Hofmann, University of Basel, Switzerland

We cordially invite fossil chironomid researchers to Basel, Switzerland, for what may be the 14th international (chironomid) deadhead workshop. The workshop will provide an opportunity to present and discuss recent results, as poster or oral presentation, network with colleagues and examine interesting or unusual fossil chironomid specimens under the microscope. In addition, we intend to discuss two timely topics for fossil chironomid research: online archiving of chironomid count data and archiving fossil chironomid microscope slides in repositories or museum collections. On the third day of the workshop we plan to have an excursion to the sites of some classic as well as some recently published chironomid studies, depending on the weather with either a visit to the Grindelwald region, where many early Swiss chironomid studies were conducted, or if the weather is poor, to some Swiss lowland sites that were studied for fossil chironomids.
