Proceedings of the Conference “Biology of the Amphibians in the Sunda Region, South-east Asia”Edited by Indraneil Das, Alexander Haas and Andrew Alek TuenCopy editor: Genevieve V. A. GeeISBN 978-967-5418-21-1 (paperback)ISBN 978-967-5418-20-4 (hardcover)Printed by Lee Miing Press Sdn Bhd, Kuching, Sarawak, Malaysia.Front cover: Amphibian metamorphosis is among the most fascinating processes in the animal kingdom that interests professional herpetologists and laypersons alike. This image captures a metamorphosing specimen of Ansonia hanitschi at Gunung Kinabalu Park, Sabah (East Malaysia). The limbs seem fully developed and functional, while the sucker-like mouth of this rheophilous larva is still intact. This species is known to have the largest larvae within the genus, reaching over	30	mm	in	total	length.	These	results	were	part	of	a	research	project	supported	by	Volkswagen	Stiftung and published in this volume. The image was taken with a Nikon D100 camera, a 50 mm Sigma	macro	lens,	at	aperture	setting	f20,	and	a	Nikon	SB-80	flash.

The	 individual	 illustrated	was	photographed	during	 the	day	at	Hutan Lipur Lata Tembaka, Terengganu, Peninsular Malaysia, using a Nikon D300 with a Nikkor 18–200	mm	lens	at	an	aperture	setting	of	f.16,	and	a	Nikon	SB-900	flash	at	a	fill	flash	setting	of	-0.2.

The island of Borneo has provided excellent opportunities for research on tropical biodiversity and UNIMAS is privileged to be given the opportunity to continue this tradition. About 50 years ago, Dr Robert Inger, then a young herpetologist, pioneered the research on the ecology of frogs in Borneo, and it is a great honour to have him as Keynote Speaker at this conference. His work inspired many researchers to study the biology of amphibians in the Sunda region. Thus, this conference,	with	its	objective	to	bring	together	the	experts	and	researchers	in	this	field	to	share	their	 experiences,	discuss	findings	and	explore	 research	opportunities,	 is	very	appropriate	 and	timely. For us in UNIMAS, and I am sure for the other researchers as well, this conference provides an important avenue for networking and opportunity to learn from one another. I thank the organizers for choosing UNIMAS as the venue for this conference and giving us the opportunity to share our hospitality with you. I hope that this conference will not only bring about greater understanding of the discipline you are discussing but also promote close cooperation, collaboration and networking among researchers.Professor Dr Khairuddin Ab HamidBIOLOGY OF THE AMPHIBIANS IN THE SUNDA REGION,SOUTH-EAST ASIA (2009)Patron: Prof. Dr. Khairuddin Ab Hamid  Vice Chancellor   Universiti Malaysia SarawakPrincipal Conveners: Prof. Dr. Alexander Haas  Biozentrum Grindel und Zoologishches Museum  University of Hamburg, Germany Prof. Dr. Indraneil Das  Institute of Biodiversity and Environmental Conservation,    Universiti Malaysia SarawakChairperson: Prof. Dr. Andrew Alek Tuen  Institute of Biodiversity and Environmental Conservation,    Universiti Malaysia SarawakSecretary: Dr. Ramlah bt ZainuddinTreasurer:  Dr. Leaw Chui PinSecretariat: Technical: Prof. Dr. Andrew Alek Tuen Assoc.

The increase in the number of publications has been accompanied by a significant	increase	in	the	number	of	scientists	working	on	the	fauna.		Most	gratifying	has	been	the	significant	increase	in	the	number	of	regional	scientists	and		students	contributing	to	knowledge	of this rich fauna.   As is common when there is a burst of research on the fauna of a region, there is an accompanying tendency to over-specialization—a small group working on one corner of the region tends to be only dimly aware of the personalities and content of work in another corner. This phenomenon is not a result of competition or lack of broader interest, but rather one of the by-products	of	enthusiasm	for	the	subject	at	hand.		Excitement	over	the	topic	at	hand	tends	to	block	out	subjects	from	a	broader	zone. It was therefore gratifying to learn of the proposed conference on “Biology and Conservation of tropical Asian Amphibians.”  The conference, held at one of the centers of interest  in the topic—Universiti Malaysia Sarawak, had the prospect of bringing together students and senior scientists from regional and international centers with interests in all aspects of research on amphibians of the	entirety	of	tropical	Asia.		And	it	succeeded	in	doing	just	that.		Biologists	from	India	debated	with those from Malaysia. Scientists from Thailand exchanged ideas with those from Indonesia. Students challenged statements of senior scientists.  Enthusiasm ruled the atmosphere. One concludes from this conference that, although we may have barely scratched the surface of what there is learn about the biology and conservation of the amphibian fauna of tropical Asia, the diversity of interests and the quality of the scientists, both students and senior researchers, are such	that	we	may	expect	significant	advances	in	our	knowledge. Robert F. IngerMESSAGE FROM THE ORGANIZING COMMITTEEIt	is	our	pleasure	to	welcome	you	to	the	first	conference	on	The	Biology	of	Amphibians	in	the	Sunda Region, South-east Asia.  The results of parallel researches conducted in the Sunda region show that the diversity of Sunda amphibians has been clearly underestimated, making the region one of the richest in amphibian	 species	 in	 the	world.	Despite	 the	 intensified	 research	 interest	 in	 amphibians	 in	 the	Sunda region, it has become evident that for known groups, even baseline data on life history, reproduction, larval life, and ecological needs of many species, are missing. Lack of these data are of particular concern for conservation and management of these important organisms.  The activities of the research group so far have been mostly separate from each other, thus limiting	synergy	and	scientific	progress	across	groups	and	borders.	The	recent	advances	published,	however, document impressively that the Sunda region holds a wealth of research opportunities for the future, some of which can be addressed if the research group bundle their efforts and resources. The purpose of this conference therefore is to bring the various groups together to discuss	findings,	opportunities	and	obstacles	to	research	and	to	explore	opportunities	for	further	collaboration. 	 We	hope	that	this	will	be	the	first	of	a	series	of	conferences	on	the	biology	of	amphibians	and	that different countries in this region will take turn to organize it. We want to thank Universiti Malaysia Sarawak and University of Hamburg, Germany for supporting this conference. We are grateful also to the Volkswagen Foundation for providing a grant to support many international participants to attend this conference. To all the committee members and participants, thank you for making this conference a success.Andrew Alek Tuen          Indraneil Das   Alexander Haas
