Pretty and poisonous: the role of plant defenses in flowers

MCZ 101, 26 Oxford Street, Harvard University

The role of chemicals in mediating plant-animal interactions in flowers is relatively unexplored. Flowers act as signals for pollinators, but may also be used by unwelcome guests such as nectar robbers, flower eaters, and seed predators. If leaves and flowers both contain defensive chemicals, it may be difficult for plants to facilitate pollination and also maintain plant defenses. Exposure to defensive chemicals in pollen and nectar has the potential to affect pollinator health. Considering the role of floral defenses will provide a more in-depth understanding of how such traits evolve, and their consequences for population dynamics of both plants and insects.

The talk is free and open to the public. The meeting is readily accessible via public transportation. Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets. Everyone is also welcome to join us for dinner before the talk (beginning at 6:15 PM) meeting at the Caspersen Student Center cafeteria, if you are late we may be at Cambridge Commons this month.

CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (6:15 to 7:15 PM) followed by our formal meeting (7:30 – 9:00 PM). The latter begins with club business and is followed by a 50 minute entomology related presentation. Membership is open to amateur and professional entomologists.

will speak about his new book

Honeybee Democracy

Geological Lecture Hall, 24 Oxford Street, Harvard University – note unusual time and place

A presentation of Harvard Museum of Natural History and CEC

Dr. Seeley with a honeybee colony.

As they face the life-or-death problem of choosing and traveling to a new home every year, honeybees employ a complex decision-making process that includes fact finding, vigorous debate, and consensus building. Thomas Seeley, world-renowned animal behaviorist and Professor of Biology at Cornell, will explore what these incredible insects can teach us about collective wisdom and democracy.

Free and open to the public. If you must drive, parking is available in the Oxford Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets.
