A Ph.D. research assistantship is available in larval amphibian ecology at the 
University of Hong Kong. This project will examine how diversity in larval 
amphibian communities regulates ecosystem responses and determine at what 
levels of complexity increasing densities and water temperature destabilize 
these communities. The project consists of experiments that: (1) Evaluate 
ecosystem responses to manipulation of diversity in larval amphibian 
communities; (2) Quantify organism-level contributions and define functional 
roles; (3) Characterize the role that larval amphibian densities play in 
mediating ecosystem responses; and (4) Examine ecosystem-level responses when 
larval amphibian assemblages are exposed to increases in water temperature.

Selected student must be able to start by January 2013. Applicants should be 
hard-working, self-motivated field biologists with a strong interest in larval 
ecology and ecosystem functioning. Field experience with amphibians is required 
and experience setting up and maintaining mesocosm experiments is preferred. 
Applicants must have successfully completed a research master’s degree in 
ecology or related field, have at least a 3.0 undergraduate GPA, and must have 
taken the GRE. International students for whom English is not their first 
language will need to have taken the TOEFL. Strong writing, oral communication, 
and statistical skills are important. Research assistantship provides a stipend 
of approximately $20,000/yr, health insurance, and a tuition waiver.

Prof. David Dudgeon of the University of Hong Kong will assume primary 
supervision; student would be co-supervised by Dr. Nancy Karraker. Prof. 
Dudgeon and Dr. Karraker maintain an active lab that focuses on stream ecology 
and conservation and currently includes five graduate students studying 
reptiles and amphibians. The medium of instruction at the University of Hong 
Kong is English. If a master’s degree has been completed, a PhD is obtained in 
three years with a relatively minor coursework load.

To apply submit the following by email: a letter stating your qualifications 
and research interests, CV, copies of college transcripts and GRE scores, and 
contact information for three references (not letters) by no later than 5 
September 2012 (early application is encouraged!) to Dr. Nancy E. Karraker, 
Department of Natural Resources Science, University of Rhode Island, Kingston, 
RI 02881 (401-874-2916; [email protected]).

Note: I will be attending the 2012 World Congress of Herpetology in Vancouver 
in August. If you will attend the conference and would like to meet to discuss 
the position, please email me as soon as possible at [email protected].
