iCCB, integrated Climate Change Biology

iCCB website

iCCB Publications

A wealth of data now exists on biotic changes that occurred over the last one to two decades, but scientific understanding of the processes involved, the magnitude of the changes, and their likely outcomes is still in its infancy, largely due to the lack of long-term baselines against which to compare these data.  The iCCB is working to provide appropriate baselines by integrating data from long-term ecological studies and the even longer-term data provided by paleontology.  A trait-based, community macroecology approach allows integration of data across the temporal and spatial scales at which climate change biologists, ecologists, and paleontologists work.  In its current phase, the iCCB is disseminating this approach through outreach aimed at researchers and university students around the world via web and strategically chosen conference symposia, through sharing of trait-based data to facilitate new research in this area, and through original research by iCCB working groups.

Leader: Jussi T. Eronen

Steering Committee: Jussi T. Eronen, University of Helsinki (Group leader); P. David Polly, Indiana University (Group leader); Mikael Fortelius, University of Helsinki; Christoph Scheidegger, Swiss Federal Institute for Forest, Snow and Landscape Research; Nils Chr. Stenseth, University of Oslo

Countries involved: Finland, Norway, Germany, UK, Switzerland, USA

Field of Research: Climate Change Biology


Synthesis of data and research themes from the fields of ecology, paleontology, and climate science.  Workshops will be used to cross-fertilize research among these disciplines, targeted sessions at larger conferences will be used to dissiminate synthetic ideas out into these varied disciplines, web-based instructional materials will be used to dissiminate best practices aimed at younger researchers around the world, a short-course will be organized (outside the US, Canada and Europe) to train young researchers, and internet databases will be used to facilitate research around the world.

Web-based instructional materials aimed at young researchers and research students to help formulate projects, database to share large data sets to make cross-disciplinary research easier, short-course aimed at researchers outside US, Canada, and Europe.

To better understand the impact of climate change on the Earth’s biota by synthesizing data on past changes in climates and organisms.  iCCB uses a trait-based approach to integrate data across paleontological and ecological scales.  The historical context provides long-term benchmarks for gauging the relative importance of adaptation, geographic restructuring, and extinction in response to current and future climate change.

(1) five to six published research papers targeting major iCCB research questions; (2) annual research workshop to facilitate core iCCB research; (3) web-based iCCB instructional material; (4) trait-based research data provided over internet; (5) targeted conference symposia and workshops to disseminate ideas and best practices.
