Název v původním jazyce

Biomass and enzyme activity of two soil transects at King George Island, Maritime Antarctica.

Popis výsledku v původním jazyce

Soil microbial properties were investigated to assess the potential of organic matter dynamics in mineral and ornithogenic soils in a cold climate. Microbial biomass, respiration, N-mineralization and enzyme activities were measured along two catenary transects crossing penguin rookeries and sea bird colonies. Ornithogenic excrements, total organic carbon (TOC) and phosphorus accumulation were major factors controlling microbial properties in Antarctic soils. Multivariate approaches (cluster and discriminant analysis) clearly distinguished the ornithogenic soils from the mineral soils based on their microbial characteristics. Microbial biomass, respiration and N-mineralization were gradually inhibited by increasing P-inputs by penguins. The metabolic quotient (qCO2) was negatively correlated to P-content, whereas all other microbial properties (microbial biomass, respiration, N-mineralization, enzyme activities) followed the patterns of TOC. Urease, xylanase, phosphatase and arylsulfat
