| Summary: | Abstract: Data on microcalorimetry and C02-evolution of soil samples and lichens from maritime and continental Antarctic habitats were compared. Values from soil samples showed a strong relationship to the organic matter content. Microbial biomass estimates determined from conversion factors were compared with biomass estimates from epifluorescence microscopy. There are basic differ-ences in the microbial biomass data among individual samples. They can be attributed to different physiological states of the microbial communities and their original habitats. Heat production correlated well with C02-evolution. Data were obtained in ranges between 1 and 220 Ã § W g d.wt for soils and 240 and 2400 j U W g d.wt for lichens. These values are discussed with regard to microcal-orimetric data from literature. 1. |
