Research Area

Stable isotope ecology laboratory (SIEL) is a group of research scientists, graduates, and undergraduates who are in POSTI (Postech Ocean Science and Technology Institute) and SEE (School of environmental science and engineering) of Postech (Pohang University of Science and Technology). Our academic mission is to elucidate survival and adaptation strategy of marine biota and structure and function of marine ecosystem in changing environment by natural or anthropogenic forcing. We understand energy flux and material cycle through marine biological network by observing trophic ecology and physiology of marine individual, community and ecosystem. We use biogeochemical, biochemical, histological, and statistical tools to cover a wide range of biological organization and diverse types of coastal ecosystem. Here are our primary ecological themes of the laboratory:
(1) trophic relationship linking primary producer to top predator in coastal habitat such as muddy tidal flat, estuaries, or sandy beach;
(2) correlation between seasonal and spatial variability of biogeochemical composition of particulate matter or phytoplankton and their trophic contribution to macrozoobenthic food web by using bulk and stable isotope analysis;
(3) an annual fluctuation of biochemical composition of mollusk and how the fluctuation is affected by physical or chemical environmental factors such as water temperature, salinity, or organic and inorganic nutrient concentration;
(4) an annual cycle of growth and reproduction of marine individual organism, especially mollusk, and estimate its biological energy budget in terms of scope for growth (SFG); and
(5) seasonal or spatial variation in primary production by stratification and creation of mixed layers in the East Sea.
