A method for determining stress in wetland plant communities following an oil spill


, : A method for determining stress in wetland plant communities following an oil spill. Environmental Pollution Series A Ecological & Biological 26(4): 297-304

Gaseous exchange chambers were used to determine the degree of sublethal stress in wetland plant communities. Air samples were collected in syringes and the CO2 concentration determined on a gas chromatograph equipped with a catalytic conversion unit to quantitatively reduce CO2 to CH4, and a flame ionization detector. The system provides an appraisal of stress by measuring the relative decrease in gross photosynthesis. The technique is portable, rapid and can be used in remote areas. It was developed to determine the effect of oil spills on a salt marsh, but can be used to determine the effects of other man-induced.sbd.as well as natural.sbd.stresses.

Whales have 1000-fold more cells than humans and mice have 1000-fold fewer; however, cancer risk across species does not increase with the number of somatic cells and the lifespan of the organism. This observation is known as Peto's paradox....
