ATBC 2008 - epiphylls

Proposed Course # 2

Biodiversity and ecology of epiphylls

Organizers: Robbert Gradstein, University of Göttingen, Germany (Bryophytes) & Robert Lücking, Field Museum of Natural History, Chicago (Lichens).

This course is to introduce the participants in the biodiversity and ecology of epiphyllous (or "foliicolous") lichens and bryophytes. The program consists of introductory lectures (day 1), a fieldtrip with observation of habitats and collecting of species (day 2), and identification of collections (days 3-4). Leaf surfaces in tropical moist forests are often colonized by photosynthetic organisms, the "epiphylls". The majority of these are lichens and bryophytes, although algae and cyanobacteria may also occur. Epiphylls possess many unique morphological and biological features that are special adaptations to their habitat. In addition, they inhabit specific niches in the forest differing microclimate, especially humidity and light. Because of their subtle ecological preferences, epiphylls are sensitive to environmental changes and are severely impacted by forest disturbance and fragmentation. They are therefore a very suitable group of organisms for studying the impact of habitat degradation on tropical biodiversity.

The course will be held June 14-17, 2008 (University of Suriname, National Herbarium). Costs for the participants only include accommodation and meals during 4 days; transport (by bus) during the fieldtrip will be covered by the organizers. Participants should bring a handlens, a collecting knife, some microscopic utensils (forceps, razor blades), and field gear. Microscopes and literature will be available. A maximum of 14 participants will be accepted. To register, please contact before April 1, 2008 the local organizer Caroline Chin at atbc2008.org -at- uvs.edu.
