Welcome to the FIB Lab!
Dr. Darren Yeo (PI) and Dr. Daniel Ng (Lab alumnus) are part of the Freshwater Crab Conservation Working Group that attained the Minister's awards (Team) for conserving the critically-endangered and endemic Johora singporensis. Congratulations!
Jia Huan Liew (Post-doctoral fellow) found that anthropogenic flow modifications on waterways have differing impacts on fish assemblages and food web structure. His research is published in Ecology of Freshwater Fish
Rayson Lim (PhD student and Research assistant) demonstrated the utility of Bayesian Belief Networks in predicting the effectiveness of biomanipulation management efforts. His research has been published in Ecological Modelling
Clare Wilkinson (ICL-NUS PhD student) found a significant association between land-use change and freshwater fish species and functional richness loss in Sabah, Malaysia. Her research has been published in Biological Conservation, and featured in European Scientist, ScienceDaily, and Mongabay
Yiwen Zeng (Post-doctoral fellow) found that climate change may not only reduce climate suitability, but also increase the overlap between Southeast Asia freshwater crabs and invasive crayfish. His research is published in Biological Conservation


The Freshwater and Invasion Biology Laboratory (FIB Lab) was set up in 2010, where we have been conducting research on biodiversity and ecology of tropical Asian freshwater ecosystems. Within this central theme, we concentrate on three, often interlinked research areas:

  • Freshwater ecology and biodiversity
  • Aquatic biological invasions
  • Freshwater decapod crustaceans

Our work covers a wide range of freshwater ecosystems and taxa, and can involve collaborative work with local and international organisations, laboratories, researchers, and museum staff.

Current research projects

The lab is currently involved in a variety of freshwater biology-related research projects, including:

  • Macrophyte-algae alternate stable states and management
  • Effects of floating solar panels on riparian biodiversity in Singapore's reservoirs
  • Trophic interactions and biomanipulation of freshwater communities in Singapore's reservoirs
  • Alleopathic effects on phytoplankton blooms
  • Impacts of antropogenic land-use change on freshwater food webs
  • Ecosystem functioning of tropical streams
  • Next-generation freshwater biodiversity assessment using e-DNA
  • Autecology, ecological niche modelling, population genomics, native-alien competitive interactions, trait-based risk assessments, and invasion pathway mechanisms (i.e. introduction, spread, impacts) of alien species such as Pomacea canaliculata, Cherax quadricarinatus, and Clarias gariepinus
