Raffles Museum of Biodiversity Research news and blogs


Raffles Museum News was the first museum blog and would be populated by some 400 blog articles posted between 2004 – 2007 when the museum was known as the Raffles Museum of Biodiversity Research. The site featured news about many interesting events, visitors, activities and animal encounters. So it is helpful to that this repository is available online.

The blog was hosted at a bespoke blog engine on the Faculty of Science server. The server was retired in 2016 and since the blog engine was no longer upgraded, this WordPress domain was setup. The blog posts were manually migrated in 2022 and this site was made public on 7th January 2023.

Over the years, news form the museum has resided in various locations:

  1. Raffles Museum wall, colour 3R prints (1990’s)
  2. Raffles Museum Latest News (2000 – 2004; a static webapge)
  3. Raffles Museum Newsletters (four issues between 2001 and 2005)
  4. Raffles Museum News II (2004 – 2007) [this site:]
  5. Raffles Museum News III (2007 – 2014) []
  6. News from the LKCNHM (2014 – 2017) []
  7. LKCNHM News (2017 –) [] – for current news form the museum

Raffles Museum News has shifted – update your bookmarks!

05 Jul 2007 – Raffles Museum News is shifting to a WordPress engine. The URL, now points to a new site.

The feed also remains the same:

This is the third version of the Raffles Museum news site, the first was prepared as html webpages (2000 – 2004), the second, this blog used Samizdat, a geeky format based on PHPosxom and Blosxom made simple (2004 – 2007) and now we are using the free blog engine WordPress. WordPress enthusiast and Raffles Museum volunteer Kenneth Pinto (NUS CIT) dropped in to help with the transition; thanks Kenneth!

I have also handed over the management and running of the site to Chua Keng Soon and Martyn Low. Have fun lads!

Mr Yeo Keng Loo, RIP

Mon 25 Jun 2007 – This morning, Greasi was shocked to read the obituary announcement that the family of Mr Yeo had put in The Straits Times. She asked Rahim and Makcik to verify the notice then had Heok Hui come up to the office. There he called ‘Ah Yeo’s’ home and his sister informed him that Mr Yeo had passed away suddenly during his Saturday badminton game (23 Jun 2007). It was a very quick way to go but he was only 52 and all of us grieve for him.

We will be visiting the wake at Block 56 Sims Drive S (9380056), tel: 6742-1230. The cortege will leave on Wed 27 Jun 2007: 12pm for cremation at Mandai Crematorium.

I wrote to our museum volunteers and friends earlier to inform them. I cited the interns blogs as snippets from their interactions with him capture a glimpse of him.

“Dear Toddycats and old friends,

I write to tell you with a heavy heart that Mr Yeo, one of the museum’s curators, passed away last Saturday, 23 Jun 2007, during his regular badminton game with friends.

I am glad that some of you had the opportunity to interact with this gentle man, including my interns who have recently been on field trips and prep work with him, see: “A hawk and two eagles,” “Crabby Search,” and Crocs ahoy!

One very telling remark amongst the posts reveal just how chatty Mr Yeo has been with our young museum volunteers and interns:

“Another interesting mission Siva set me and Danliang on today was to collect bird specimens. He was informed of a donor who decided to donate her uncle’s collection. We went along with Mr Yeo. It was a rickety ride in a mini-lorry to Bukit Batok. We were pretty much clueless about where block 227 was, but three brains and 6 eyes set things right.

While waiting for the donor to arrive, we pried into Mr Yeo’s life. Hee.. He’s been in the museum so long, he’s seen Prof Ng come as a student and rise as the new director! We discovered museum life changed when Prof Ng came. More specimens were collected and preserved. Before that, it was pretty much maintenace. Mr. Yeo’s been thought of as a shy man, but I think it’s delightful talking to him once he gets going. =)”

I myself am glad for the time I have had with him, particularly on specimen retrievals (the highlight must be the Tekong dugong), field trips (the last was crabbing at Ivan Polunin’s house and the Mera Lodge stream), and plotting about gallery and education programmes.”

Mr Yeo has always been kind, helpful and friendly with the people he had come across and several friends responded immediately by email, phone and SMS after I sent alerted them by email this morning, soon after I found out. Here are a few of their thoughts:

Adrian Loo (formerly Plant Systematics Lab, NUS Biological Sciences), who amongst other things, was on the memorable Changi Tree (Hopea sangal) run with Mr Yeo, responded:

“Thanks for the info. That’s really sad. He was a damn nice person always ready with a smile. I don’t think I have ever seen him without him smiling warmly. And it was always easy to strike up a conversation with him and he’d always have good stories to share about BioD and the museum.”

Alvin Wong (former hons/MSc student, Systematics & Ecology Lab, Dept Biological Sciences) says,

“Mr Yeo is always quiet and unassuming but always kind and helpful to students in the museum and on field trips. he’s a repository of info about specimens stashed away in some obscure corner.”

Ria Tan ( & Raffles Museum Honorary Museum Associate) says,

“I first met Mr Yeo when I spent hours photographing the specimens from the first Chek Jawa transect at the museum. It was my first time doing anything like this and he was patient in showing me how to do it right (and to survive the formaldehyde).

I met him many times later again, at field trips, during visits to the museum.

The wildfilms crew will always remember the special trips he made possible for us last year. Then, as always, he quietly offered sound field advice, and patiently looked after everything.

Mr Yeo’s kind and gentle friendship will be sorely missed.”

Mr Yeo crabbing in Ivan Polunin’s stream, 15 Jun 2006.

Chim Chee Kong (former Raffles Museum Snakehunter) said,

“I remembered Mr Yeo as the very nice, kind, patient and helpful gentleman who helped me in locating specimens a couple of years ago.”

Loh Lih Woon (former hons student, Systematics & Ecology Lab, Dept Biological Sciences) said,

“I’m shocked and dismayed. He was a helpful and unassuming man who made the madness of my hons year that more bearable, exactly 10 years ago! Well those whom God love die young(er) they say. Perhaps this cliched saying could serve as solace.

Sigh. The brevity of life. Seize the day we must all. RIP, Mr Yeo K L!”

Airani S (Senior Volunteer Project Manager, Raffles Museum):

“Mr Yeo is a very kind man and always accommodating to last minute requests for help. He was a shy man of very few words but as I got to know him better, he became more chatty and began to share his dreams and plans post-retirement!

I will miss his absence from the museum dearly.”

Peter Ng (Director, Raffles Museum):

“It came as a shock when I was told this morning that he had passed on – I have known him for over 27 years – since he joined as a fresh staff and I was still an undergrad working in the then ZRC. I remembered how he was full of energy and passion for his work with specimens, and especially crabs and related invertebrates. He took care of the crustacean and invertebrate collections for most of his career, and was also the key man in many of the museum’s local field collections and field work.

Those who have worked with him in the museum and the field like him and have commented on his kindness and willingness to help. All the museum’s foreign scientists whom he has worked with have remarked how good a worker he was. That he was still young and the manner of passing so sudden and unexpected makes the loss even more painful. I do not know really what to say — he will be missed … and the museum will feel the loss. Damn.”

As we shared tales of Mr Yeo with his six siblings and the rest of the family, they have been getting to know this other side of him – his museum curator’s work, love of animals, exhibition presentation skills, love of field trips and because he was such a worrier, his unexpected sense of adventure!

Marcus Ng on Wong Siew Te’s Sun bear talk

Marcus Ng came away with a new understanding of the Sun bear’s biology and a grim understanding of the fate of the sun bear in Malaysia and South East Asia, after attending Wong Siew Te’s talk on “The ecology and conservation of the sun bear in Malaysia.”

“About halfway through his presentation, bear researcher Wong Siew Te showed a duotone slide. Pictured was a small sun bear cub, with a rather rotund body and bright, pleading eyes. It was trussed up like a chicken.

Right after the photograph was taken by a Japanese researcher in Borneo, the cub was taken to a kitchen and slaughtered as it screamed.”

“About the size of a large dog but with vastly greater bulk (males reach nearly 60 kg), the Malayan sun bear is the world’s smallest bear species and the least known. The only true tropical rainforest bear (a ghostly subspecies of the black bear lives in Canadian rainforests), the sun bear is a big-headed animal with sleek black fur and a yellowish mark of varying size and shape on the chest that serves to distinguish individuals. Feet bearing long curved claws help create suitable openings in tree holes for the animal to search out insects and honey using its very long tongue, as evident in the casualty on the right, which was shot simply because it was seen and its existence deemed intolerable.”

“According to Wong, the sun bear is now “almost gone” from Vietnam, found only in some national parks in Thailand (which incredibly cover barely a tenth of the country’s vast land area), and exists in fragmented populations in Sumatra. In Peninsular Malaysia, the bears are concentrated in forest complexes such as Taman Negara, the Titiwangsa range and the Southern Forest Complex (of which Endau-Rompin National Park is but a slice). Like many other sympatric megafauna, sun bears need undisturbed forests to thrive. So as the trees are felled and land cleared of its carbon-stripping units, the earth simmers and mourns the growing loss of creatures that have survived ice ages but not the fatal pincer of man’s insatiable hunger for land, lumber and lips-smacking mammalian delicacies.

As ecologist Richard Corlett noted recently, many long-studied forests in Southeast Asia have nothing left but deer and boar, and some not at all. And as the elephants, rhinos, orang-utans, gibbons, tapirs and bears vanish, they take with them the future generations of trees that once relied on these beasts to disperse their seeds and carve new clearings in the jungle where saplings might sprout.”

Wong Siew Te on emaciated Sunbears

There were grim moments at Wong Siew Te’s sunbear seminar last afternoon. In an email to FOYers, I said:

“Speaker Siew Te made an observation about the critical role figs trees play. In 1997/8, the region experienced the most severe El Nino event. This led to the local extinction of fig wasps (due to direct impact and the haze). In the absence of pollinators in 1999, fig trees aborted their fruits [he cited Rhett Harrison’s work], and there was a famine in Sabah and Kalimantan, at least (this is where there were sun bear researchers).

Orang utans managed to resort to other food sources like young shoots and plant sap, but animals like sun bears and bearded pigs starved. All his six radio-collared sun bears were emaciated and two died (see photo). I know this led to starving bearded pigs attempting to raid field centres as well. This is suspected to be a reason for the very low density of large animals in Bornean rainforests.”

You can read more from the links at his seminar page or wait for Marcus who will blog more about this later.

“Fighting for survival.”
“Friend of bears.”

About the speaker – Wong Siew Te was born and raised in Penang, Malaysia. He earned a Diploma in Veterinary and Animal Science from the National Pingtung University of Science and Technology, Taiwan, and both a Bachelor of Science and Master of Science in Wildlife Biology from the University of Montana, USA. He is now a Ph. D candidate in Fish and Wildlife Biology, at the University of Montana, and conducting his doctorate field study on Malayan sun bears (Helarctos malayanus) and bearded pigs (Sus barbatus) in Sabah, Malaysia. Wong studied the ecology of Malayan sun bears in a rainforest of Malaysian Borneo as his M.Sc. thesis project [online pdf of his thesis]. The study contributed to our knowledge of many ecological aspects of the sun bear and promoted various conservation issues related to the Bornean rainforest.

Besides bears and pigs, Wong’s interests also include the other medium and large mammals especially carnivores, the interactions between wildlife and tropical rainforest ecosystem, and mast fruiting in Southeast Asia. Wong was appointed as the first co-chair of the Sun Bear Expert Team for the IUCN/SSC Bear Specialist Group from 2002-2005. He is now a member of IUCN/SSC Bear Specialist Group and Pigs, Peccaries, and Hippos Specialist Group.

Mangrove Dollies! By Patrick Grootaert & Igor Shamsev

Long-legged flies (Order Diptera, Family Dolichopodidae) are the passion of Belgian entomologist Patrick Grootaert.

In Feb 2005, we announced his stay with the Raffles Museum of Biodiversity Research. Patrick, who is Head of the Department of Entomology at the Royal Belgian Institute of Natural Sciences, was on sabbatical leave here from 1st March 2005 to 28th February 2006. Explaining then that his research interest was the taxonomy, systematics and sexual behaviour of Empidoid flies, we had no idea of the limelight he would cast onto this group!

Photos of dollies | Marcus Ng

As a warm-up of what lay ahead, his paper with Igor Shamsev was published shortly after in April 2005. There he had described two new species – C. nigripennis was based on a holotype collected from Sungei Buloh and C. singaporensis, from a holotype caught in Chek Jawa.

Almost a year later, we had exciting news. But we saved a “little” titbit for the newspapers and on 6th February 2006, The Straits Times (Singapore) ran a story that screamed “150 new species of flies found.”

Two weeks later at his farewell seminar, he revealed that he lay awake at night wondering how he would finish describing all those new species and that within his insect traps there were probably more species in other groups waiting to be discovered! I remember feeling thrilled that even more mangrove insects were being described and dismayed that we could lose many to extinction.

Patrick went from reverence to amusement, cracking the crowd up when he revealed the names he had provided for new species – he had named dollies after various members of the research community and some had very interesting etymology!

By now, in the biodiversity community in Singapore at least, the term “dollies” was firmly etched in our minds as dipterans in the family Dolichopodidae. This was no mean feat, for the flies had to supplant the otherwise popular Dim Sum Dollies!

In late May 2007, the latest in a series of papers was published. It is the “Revision of the genus Elaphropeza Macquart (Diptera: Hybotidae) from the Oriental Region, with a special attention to the fauna of Singapore,” by I. V. Shamsev & P. Grootaert. Zootaxa, 1488: 164 pp., 31 May 2007 [pdf]. In this monograph, 59 new species of hybotid flies in the genus Elaphropeza are described – remarkable since only 79 were known of this group before!

‘Of the 51 new species only 43 have been given a name.’ And amongst the names of new species are names of familiar places and people that Patrick had energetically proclaimed, at that seminar in February 2006! They include:

  • Places – E. sime, E. neesoonensis, E. chekjawa, E. bulohensis, E. temasek and E. ubinensis.
  • People – E. yangi, E. yeoi, E. benitotani, E. luanae, E. darrenyeoi, E. murphyi, E. meieri. E. ngi, E. riatanae and E. sivasothii.

Marcus Ng gets lyrical and pens “Names on the fly,” The annotated budak, 14 Jun 2007.

“The Belgian entomologist Patrick Grootaert has been busy surveying habitats in Singapore and Southeast Asia in recent years, seeking tiny flies that mostly thrive only in moist, muddy and mangrove-infested swamps. Little is known about them other than their existence and until Grootaert came along, many lacked names. Often, their presence is indicative of habitats that are pristine and consequently most at risk of degradation from human activities.

Fourteen of these new species are found only in mangroves and the bulk of samples were collected right here in Singapore over a year. Grootaert notes that despite the extensive sampling, a third of local species are known only from singletons and doubletons, suggesting that “a large number of species still remain undiscovered.”

“The obvious message for conservation from Grootaert’s paper is that a vast mountain of unknowns lies within the borders ofÊ this tiny island, which prides itself in biotechnology leadership but seems loathe to protect the unique and irreplaceable genotypic wealth that yet dwell in its diminished ecosystems. “

Urban Escape episode featuring Raffles Museum on TV Mobile this week

Since Wed 13 Jun 2007, friends have been telling me that they have seen an episode of Urban Escape featuring the Raffles Museum on TV Mobile – they caught the show on a television screen on a bus. It was a vague memory and after hunting the blog archives, I realised why. This episode was first broadcast around April 2005. The series explored lesser-known places in various parts of Singapore with hosts Jeassea Thyidor and Timothy Nga. The museum was featured in the episode on the western parts of Singapore.

I haven’t seen the episode myself but I do recall they shot scenes in the Public Gallery and the Wet Collection. All the comments say it was quite a nice episode, so I do hope I catch it one day. According to the schedule episodes of Urban Escape will be shown again at 6pm and tomorrow at 10am, 10.30am, 3pm, 8pm and 9pm. No wonder so many of my friends have seen it this time – much more than the original broadcast.
