Wisconsin Ecology 15th Annual Spring Symposium


Dr. David Jablonski

This year, we are pleased to host Dr. David Jablonski, William R. Kenan, Jr. Professor in the Department of the Geophysical Sciences, University of Chicago.

Dr. Jablonski's research emphasizes the combining of data from living and fossil organisms to study the origins and the fates of lineages and adaptations. Main areas include: (1) the dynamics of the latitudinal diversity gradient in marine bivalves, and the interplay or origination, extinction, and range shifts in shaping global diversity patterns. The fossil record shows that the "tropics-as-cradle-or-museum" paradigm of the past 30 years is a false dichotomy, with the tropics actually being an evolutionary source of expanding lineages that also accumulate in their tropical starting points. (2) The role of geographic range, larval development, and other biological factors in determining speciation rates and patterns in mollusks of the Coastal Plain Cretaceous and the Cenozoic. Hierarchical approaches to large-scale evolutionary processes appear to be powerful tools for understanding macroevolutionary patterns. Once background patterns are understood, they can (3) be compared to patterns of extinction and survival during mass extinctions to gain a better picture of the evolutionary significance of extinction events. Work on the end-Cretaceous extinction indicates neither a simple intensification of background patterns nor an entirely random culling of the biota, and analyses on the early Cenozoic evolutionary rebound shows distinct differences among biogeographic regions (North America vs. Europe vs. North Africa vs. Pakistan), suggesting that evolutionary patterns are shaped by the alternation of extinction regimes, with rare but influential mass extinctions driving unexpected evolutionary shifts. Analysis of both background and mass extinction along latitudinal and bathymetric gradients, and spatial and environmental histories of major evolutionary novelties and higher taxa in post-Paleozoic marine invertebrates, are also active research projects based on the primary literature and museum collections.

Call for Abstracts!

The Wisconsin Ecology Graduate Committee is soliciting abstracts for the 2012 Wisconsin Ecology Spring Symposium. We are seeking grad students and post-docs, with preference given to dissertators near completion, to present their research in either a 15 min oral presentation or as part of a judged poster session (details below). Abstracts (1 page max) are due to the Wisconsin Ecology Graduate Committee by February 29 and all applicants will be notified of a decision by the first week of March. Applicants may submit abstracts for an oral and/or a poster presentation. Space in the oral session is limited! If you are not selected to take part in the oral presentation session you will be asked to take part in the judged poster session.

If you are eligible, please consider this wonderful opportunity to showcase your research to colleagues and peers from across campus. If you are not eligible, please share this invitation with someone who is, and tell them you want to hear them give a talk or see their poster this coming March 28th and 29th!

All submissions should be emailed to wisconsinecology@mailplus.wisc.edu


Judged Poster Session
Wednesday, March 28 6:00-7:00pm
1106 Mechanical Engineering
1513 University Avenue

Those invited to present their original research in poster form are asked to accompany their posters during the reception and poster session immediately following a presentation by Dr. David Jablonski on Wednesday evening. Posters will be judged by a committee comprised of members of the Wisconsin Ecology Graduate Committee and Dr. Jablonski. Recognition and awards of highly judged posters will be made public prior to Dr. Jablonski's talk the following day.

Posters must be no larger than 40" x 30" and will be affixed to poster stands (48" x 36" will fit, but may be a little tight). Posters should follow the standards of professional scientific meetings (one example can be found at this URL: http://www.agu.org/focus_group/GEC/Criteria_for_Judging_OSPA.pdf) and prizes will be awarded for the categories "Best Undergraduate", "Most Novel Research", "Most Creative", and "Most Wisconsin Idea." Winners in each category will receive a prize (approx. $40 total value). Presenters will be asked to leave their posters with the Wisconsin Ecology Graduate Committee for display at the symposium events the following day, and are highly encouraged to accompany their poster prior to and following Dr. Jablonski's talk.M


Oral Presentations
Thursday, March 29 2:00-3:30pm
Genetics Auditorium
425 Henry Mall

Those invited to present their original research in an oral presentation are asked to prepare a 15 minute talk to be given during a special session preceding the keynote address by Dr. Jablonski. Talk content should be no longer than 12 minutes allowing 3 minutes for questions by the audience, following the standards of presentations at professional society meetings. The session will be strictly moderated by a member of the Wisconsin Ecology Graduate Committee.

In assessing participants of the symposium for inclusion into the oral presentation session the Graduate Committee will focus on originality of research, broad appeal to ecologists on campus, and seniority of applicants with preference given to dissertators approaching completion of their degree.
