Paper Abstract

From several single arthropods methane and water vapor release is measured with a time resolution of 15 seconds by a liquid nitrogen cooled CO-laser intracavity photoacoustic arrangement. Atmospheric methane is an important component in the process of global warming and ozone depletion. Four taxa of arthropods are thought to be responsible for up to 25% of the total mondial CH4 release to the atmosphere. The measurement of water vapor release together with CO2 emission is of importance for understanding the complex breathing pattern of arthropods, in view of evolutional adaptations these animals have undergone to survive terrestrial conditions.
