• Freshwater ecology and biodiversity
• Aquatic invasions
• Freshwater decapod crustaceans (systematics, taxonomy, and conservation)
Projects (together with students, staff, and collaborators) include biodiversity surveys and ecological studies of Singapore’s freshwater fauna such as plankton, invertebrates, and fishes; ecological studies of aquatic alien species in Singapore and tropical Asia; and systematics and taxonomy, and conservation of freshwater crabs and other decapod crustaceans.
1. Freshwater ecology and biodiversity – Ongoing ecological work focuses on Singapore’s streams and reservoirs including investigations of toxin production by cyanobacteria and their responses to environmental variables; food web and trophic interactions; and origins and ecology of freshwater molluscs.
2. Aquatic invasions – Investigating invasiveness, ecology, and impacts of aquatic alien species, e.g., competitive interactions between introduced and native freshwater snails, decapod crustaceans, gobies, gouramies, catfishes, and frogs. Introduced species currently being studied include the golden apple snail (Pomacea canaliculata), redclaw crayfish (Cherax quadricarinatus), marbled goby (Oxyeleotris marmorata), Midas (Amphilophus citrinellus) and Mayan (Cichlasoma uropthalmus) cichlids, and African sharptooth catfish (Clarias gariepinus), Guenther’s frog (Hylarana guentheri) and American bullfrog (Lithobates catesbeianus).
3. Freshwater crabs – Work includes systematic and taxonomic studies of Asian freshwater crabs; global IUCN Red List conservation assessments; and ecological and conservation studies of critically endangered species, e.g., the Singapore freshwater crab (Johora singaporensis).
