  Effects of urbanisation on insect biodiversity

   Biological Sciences

  Assoc Prof Eunice Jingmei Tan  Applications accepted all year round  Funded PhD Project (Students Worldwide)

About the Project

Urbanisation is among the greatest threats to existing biodiversity. Recent studies reveal a worldwide decline of arthropods, threatening the sustainment of essential ecosystem services such as pollination and food webs. Habitat loss and light pollution through artificial light at night are thought to be important consequences of urbanisation that contribute to loss of arthropod biodiversity. However, this insight derives almost exclusively from research on species from temperate Europe and North America, and our understanding of the effects of urbanisation on the diversity and abundance of terrestrial arthropods within an urban context in tropical Southeast Asia is conspicuously lacking. Using a combination of techniques such as field surveys, morphological analyses, DNA barcoding and behavioural experiments, this project will investigate the effects of urbanisation on arthropods and the underlying mechanisms within such an urban environment.

All applicants must possess at least four years of undergraduate study or three years of undergraduate study with a Masters degree. We consider an applicant's Grade Point Average (GPA) an important factor in assessing their suitability.

All PhD applicants must submit GRE (Graduate Record Examinations) scores ( The minimum score for GRE (General Test) should be Verbal and Quantitative Abilities: total score of 320, Analytical Writing: 3.5.

As the medium of instruction at NUS is in English, applicants whose native tongue or medium of undergraduate instruction is not English, should submit TOEFL/IELTS (Academic Test) scores as evidence of their proficiency in the English Language. The minimum TOEFL score is 580 (Paper-based Test), 260 (Computer-based Test) and 85 (Internet-based Test). The minimum IELTS score is 6.

Although you could feel free to discuss potential projects with individual professors in our Department, your application will only be evaluated by the Graduate Committee in the Department. Only when you are recruited by the Department, you will have a chance to rotate in different labs and eventually choose your supervisors.
