Field Research Position in Panama

Project Description:
Tropical forest ecosystems have been found to be undergoing widespread changes. Of particular
concern is the increasing dominance of lianas (woody climbing vines). I am investigating whether
increasing CO2 is a viable explanation for increasing liana dominance and, if so, through what
mechanism CO2 favors lianas over trees. The study is being conducted at the Smithsonian Tropical
Research Institute (STRI) in Panama. Liana and tree species are growing in open-top plant growth
chambers and exposed to elevated levels of CO2.

Position Description:
Research assistants will have the opportunity to work closely with a PhD student to carry out a
major research project. You will learn the design and operation of an elevated CO2 growth
chamber array, including instrumentation to measure CO2 levels and the photosynthetic activity of
plants. Other duties may include plant identification and collection, caring for seedlings, and
measurement of plant traits. This is a volunteer position intended for persons looking to gain field
and research experience. Partial reimbursements for travel may be available depending on the

Ability to work long days in the field under tropical conditions (intense heat, rain, sun,
biting/stinging insects), and a basic understanding of biology and/or ecology. Spanish language
proficiency is preferred but not required. Positions start immediately and will run to mid-June.

Please send short cover letter (including earliest start date) and resume (with references) to Dave
Marvin ( or visit for more
information. Applications accepted until May 1st.
