Because of some missed communication, my notices about seminars have been scarce, and I apologize for that. So far there have been three fabulous seminars this term (2 last week, 1 the previous week). All are welcome, and drinks and snacks will be available. Usually the seminars are on Thursdays at 11:30 a.m. in Patterson Hall 308 (Biology Bldg.) -- going up Univ. Ave. from Main St., count 4 buildings on the right, and that is Patterson Hall. Acadia Biology Seminar THURS. at 11:30 a.m., Patterson Hall Room 308: > From: Aaron Shafer [mailto:080282s@acadiau.ca] > Sent: Friday, September 22, 2006 3:15 PM > To: 'Nancy Roscoe-Huntley' > Subject: re: seminar next week > > Hi Nancy, I¹m not sure when this goes out, but here¹s the write up for next > week¹s seminar. > > > > Dr. Christian Lacroix, University of Prince Edward Island > > "Morpho-EVO-DEVO: the plant morphology context² > > > > Classical plant morphology and dynamic morphology represent two theoretical > frameworks used to describe and understand the 'body plan' of vascular > plants, especially flowering plants. Generally, plants are interpreted in > terms of three mutually exclusive structural categories: stem, leaf, and > root. Stem and leaf together constitute a shoot which usually shows > axillary branching. According to the classical approach, organ identity can > be predicted by its relative position on the plant body. This model applies > to many but not all flowering plants. There are groups with forms that do > not clearly fit into the classical model. In these cases, a dynamic > morphological perspective may serve as a more encompassing model. It > accepts developmental mosaics between stem, leaf, and root. This continuum > model was revived during the pre 'EVO_DEVO' period by Agnes Arber, Rolf > Sattler, and others.
