Specimens make their mark at the ASEAN Wetland Management Training Course

Specimens from the Raffles Museum do not always stay in the museum, some get to travel! Research specimens typically move in and out with some frequency, typical to any research collection. Specimens may be loaned out for special occasions such as the recent loan to National Heritage Board of the large, old specimens from the former Raffles Library and Museum for display at the Asian Civillisations Museum for their “Hunters and Collectors: The Origins of the Southeast Asian Collection” exhibition.

Smaller specimens typically also travel out for public education events with the Raffles Museum Toddycats during special events such as Envirofest and Sungei Buloh Wetlands Reserve Anniversary. For undergraduate teaching, the specimens also make an appearance at the Department of Biological Sciences such as the Labrador rocky shore preparatory practicals for the new second-year ecology module, LSM2251.

Last Sunday, 16 bottles (8 of fish, 8 of crabs) were prepared and packed with lots of padding by Kelvin Lim and Tan Siong Kiat into a styrofoam box for Research Associate N. Sivasothi. He conducted a conducted half-day mangrove fauna workshop at Sungei Buloh Wetlands Reserve (SBWR) for the ASEAN Wetland Management Training Course coordinated by NParks staff at SBWR. Individual sessions were conducted by volunteer instructors from NParks, NTU and NUS.

Sivasothi’s session was conducted as a lecture in two parts on common mangrove fauna interspersed by field observations at the Visitor Centre mangrove boardwalk and ended with a demonstration using the specimens.

The use of specimens was effective in providing a close up view of several features in various fauna which had been discussed or observed earlier. This also gave rise to a tutorial on preservation techniques and a discussion the importance of curating a faunal collection at wetlands sites for staff training and education.

The locality data and date of collection on labels in each bottle was the subject of some discussion too, as it highlighted the importance of regular collections over time and proper preservation techniques that allow well preserved and carefully handled specimens to be used over centuries.
