Title: Taxonomy and conservation – Field Identification of dipterocarps

 

Synopsis: We need to be able to identify primary forest trees such as dipterocarps to better manage and conserve our nature reserves.  But what if the tree is 30 m tall, and all we can see is its bark and fallen decaying leaves? This project is divided into two parts:  one group will aim to develop a system to identify 10 most common dipterocarp species using accessible characters; the other group will kickstart development of a computer visual pattern recognition system.

Principal Investigator: Dr Jeffrey Lee; Dr Tan Guoxian

Pre-requisites: a) Independent and committed to the project; b) strong interest in plant biology and/or computer science; c) will involve field work

Title: Spatial distribution of Hippocampus kuda and H. comes in Singapore

Synopsis: Two species of seahorses have been observed off the islands and coastline of Singapore- the yellow seahorse Hippocampus kuda and the tiger-tailed seahorse H. comes. From anecdotal reports, H. kuda is thought to be an estuarine species while H. comes has only been found on coral reefs in Singapore. This project would assess if the two seahorse species in Singapore demonstrates habitat diversification. Habitat data will be collected through a combination of fieldwork and meta-data extraction from seahorse photographs shot in Singapore that are available online. The student will learn how to identify the common seahorse species found in Southeast Asia, confirm seahorse sightings in Singapore, and report all seahorse sightings to http://www.iSeahorse.org.

No work on live or dead seahorses is involved. 

Principal Investigator: Dr Abigayle Ng (RSI) & Dr Tse-Lynn Loh (Shedd Aquarium)

Pre-requisites: a) Interest in biodiversity; b) able to take initiative and work independently; c) have good social skills.

Title: Population genetics of Hippocampus kuda and H. comes

Synopsis: This project would assess the genetic diversity of seahorses in Vietnam. Because seahorses are hypothesized to have limited dispersal abilities, seahorse populations may be highly structured and genetically distinct within small biogeographic regions. In this study, students will learn how to extract seahorse DNA, determine the best sequences to use in this study, and run population genetics analyses. All seahorse genetic sequences will be uploaded to GenBank (http://www.ncbi.nlm.nih.gov/genbank/). The data from this study can help uncover the resolution at which population genetic studies can be used to determine the sources of seahorses found in trade and possibly aid in the conservation of seahorses in South East Asia.

Principal Investigator: Dr Abigayle Ng (RSI) & Dr Tse-Lynn Loh (Shedd Aquarium)

Pre-requisites: a) Interest in molecular evolution and conservation; b) must be committed and able to work independently.

Code: B006 (2 spaces available)
Title: Development of a solvatochromism based molecular aggregation prediction model

Synopsis:

Molecular aggregation is a common phenomenon with profound implications on the photophysical, photochemical and biomedical properties of materials. For example, the aggregation of the β-amyloid peptide in the brain is related to Alzheimer’s disease; the aggregation of protein LHCIIb forms part of a critical route for plant leaves to nonphotochemically dissipate excess photons required for photosynthesis and regulates light harvesting.

This project aims to establish a quick and low-cost method to quantify the level of molecular aggregation, based on spectroscopic data (UV—vis absorption and fluorescence spectroscopies). Small organic dyes will be used to test and evaluate this model, while our final goal is to implement such a model in drug-screening, i.e., for the treatment of Malaria.

Both experimental measurements (using various spectroscopies) and data analysis will be carried out by the student under the supervision of a researcher at SMART. At the end of the project, a journal publication is expected while the student may serve as a co-author based on his/her contributions.

Principal Investigator: Dr Liu Xiaogang (SMART) and Dr Lee Zhiying (RSI)

Pre-requisites: Strong in Physics and Chemistry, will require knowledge of Matrices (Mathematics). Available for full time attachment during June and Dec holidays.

Remarks: Selection will be on individual’s attributes i.e. pre-formed groups may be broken up. This project will be conducted off-campus at external laboratory at NUS-CREATE.

Title: Biophysics – Use of 3D printed models to study the aerodynamics and wind  dispersal potential of fruits from native and introduced climbing vines of the family Malpighiaceae

Synopsis:  This project seeks to use 3D printing to understand the aerodynamics of the wind dispersed fruits of three climbing species of Malpighiaceae, a family of popular ornamental plants: Aspidopterys concava is a locally endangered native species with isolated populations in the Central Catchment Reserves;  The Maiden’s Jealousy (Tristellateia australasiae) planted extensively in our parks and gardens are introduced clones whilst the remaining native populations survive only in small mangrove areas in the north.  The introduced Helicopter Flower (Hiptage benghalensis) has naturalized in our central catchment forest and is known as one of the most invasive plant species in the world.  Knowledge gained about the wind dispersal potential of the fruits of these three species will contribute towards biodiversity conservation in very different ways.
