International Biogeography Society Conference – Bayreuth, Germany

7th biennial conference

University of Bayreuth, Germany
Report by Erik de Boer

Two weeks ago I attended the biannual International Biogeography Society (IBS) conference in Bayreuth, together with 600+ other people from more than 50 different countries. This IBS conference, my first IBS meeting, proved to be an exciting event during which I met scientists from many different disciplines and heard talks on cutting-edge biogeographical research.

The IBS conference was held in the Bavarian city of Bayreuth, in the middle of the biodiverse landscape of Upper Franconia. This landscape provided the training ground for Alexander von Humboldt, the founder of the field of biogeography. The 4-day conference included a wide variety of symposia and many, many posters. The conference dinner in the German Steam Train Museum was highly memorable. The conference was closed by a lecture from Daniel Simberloff, once a doctorate student of Edward O. Wilson, who received the Wallace Award for his outstanding contributions to invasion ecology.

Erik_PicI had a talk in the plenary symposium of ‘Ecosystem response to past climate change’, organized by David Nogués-Bravo and Francisco Rodríguez-Sánchez. The symposium covered the dangers of climate change to biodiversity and tried to assess if the range and rate of adaptation, migration, persistence, or extirpation, that are registered in deep-time records, palaeorecords, and the recent past, are adequate responses for predicted climate change in the future. I addressed this issue from the point of view of a small remote island, where migration is obviously a limiting factor. I showed how I reconstructed climate and its effect on island biota during the last 40,000 years using long-term palaeoecological records from Mauritius (de Boer et al, 2013 & 2014). These records show that different climate regimes result in different ecosystem response to climate change in the past. Local extirpation or population collapse of larger vertebrates was a natural phenomenon in the lowlands of Mauritius due to frequent climate extremes (I will discuss this in more detail in my next blog; de Boer, 2015). Despite these population collapses, island biota have always (in the timeframe of my records) survived natural climate change. Therefore, my take home message was not to focus on the effects of (future) climate change alone. Other key components of global change, such as invasive species and habitat destruction, are more imminent threats to the biodiversity of many islands. For more information on my research, including publications, click here.

About the International Biogeography Society

The International Biogeography Society (IBS) was founded in 2001 to provide a platform (conferences, journal, social media) to discuss the increase in biogeographical research; facilitated by an enormous increase in the data available on species distributions and the environment, and the development of novel techniques in phylogeny and environmental modelling. The biogeography field includes researchers from not only ecology and evolutionary biology, but also includes researchers with backgrounds in physical geography, palaeobiology and palaeoecology, global change ecology and conservation. The synergy of all these different scientific approaches allows for a novel assessment of biodiversity patterns in the past and predictions for the future. Paleoecology plays an important role in the recent surge of biogeographical research, as it provides long-term records of ecosystem and species dynamics to confirm or challenge biogeographical theory across different scales in space and time.
