Orchid symbioses: models for evolutionary ecology

Poster abstract submission deadline – has now passed. Thank you to everyone who submitted a poster. We will be publishing the abstract book on-line ahead of the meeting.


The number of posters are limited and so will be restricted to one poster per presenting author and be subject to a selection procedure based on submitted abstracts. Preference will be given to new unpublished, or recently published, work. Please send your abstracts according to the guidelines below by 8 March 2013. You will receive an email by 22 March 2013 informing you whether or not your abstract has been accepted as a poster and if you have been chosen to give a 20 minute oral presentation of your work (15 minutes presentation; 5 minutes for questions).

Note there will be prizes awarded for the best posters. Poster abstracts will be published in the symposium program and abstract book and will be made available on the symposium website.

Example abstract:

The origin of Helianthus deserticola: survival and selection in a desert habitat

Department of Biology, Indiana University, Jordan Hall 142, 1001 East Third Street, Bloomington, IN 47405, USA


The diploid hybrid species Helianthus deserticola inhabits an extreme environment relative to its parental species H. annuus and H. petiolaris. Adaptation to the arid desert floor may have occurred via the acquisition of novel phenotypes resulting from transgressive segregation in early hybrids. We have explored this possibility through a field experiment designed to test the direction and intensity of phenotypic selection, using crosses between the parental species as proxies for the ancestral genotype of the ancient hybrid species. Helianthus deserticola, H. annuus, H. petiolaris, and early-generation hybrids between H. annuus and H. petiolaris were all grown in native H. deserticola habitat, and a selection analysis revealed that several traits were subject to strong selective pressures. Several of the traits under selection were also extreme or transgressive in H. deserticola, and the range of variation present in BC2 hybrids suggests that many aspects of the H. deserticola phenotype are easily recreated. Thus, transgressive segregation may have contributed to the adaptation of H. deserticola to the desert habitat.
