Joanne & Aisyah on “Investigations into mangrove tree-climbing crab biology: Gastric mills and Larval periodicity”

Communicating research findings to managers and educators – A talk for staff and volunteers of Sungei Buloh Wetlands Reserve

“Investigations into mangrove tree-climbing crab biology: Gastric mills and Larval periodicity”

By Siti Aisyah Bte Jamal & Joanne Khew
Systematics & Ecology Lab
Department of Biological Sciences, NUS

Saturday 29th May 2010:
11.15am – 12.15pm (with Q & A)
Sungei Buloh Wetlands Reserve Theatrete

About the talk
Crab digestion is aided by the appearance of hard structures in their stomach which are called gastric mills. Bearing an uncanny resemblance to the molar tooth row of mammalian herbivores, Aisyah investigates the diversity of the morphology of gastric mills in tree-climbing crabs and evaluates the conformation of phylogeny compared to diet.

Although most mangrove crabs bear large numbers of eggs which are released as larvae into estuarine waters, little is know about the plankton. Joanne’s investigation sheds light into the morphology of tree-climbing crab larvae, sheds light into their periodicity and abundance and discusses the implications as well as a mysterious disappearance event.

About the speakers
Aisyah and Joanne completed their honours year at NUS in May 2010 and are currently awaiting their final results. In their final year, they embarked on research projects into aspects of the biology of tree-climbing crabs under the supervision of Ng Ngan Kee and N. Sivasothi. After a year of mud, tides and dissection, they are no longer strangers to crabs or the mangrove!
