THE MICROBIAL FOOD WEB : COMPARATIVE STUDY UNDER FIRST-YEAR ICE AT LOW AND HIGH LATITUDES IN THE NORTHERN HEMISPHERE (16th Symposium on Polar Biology)
In spring of 1992, the microbial compartment at the base of first-year ice in Saroma Ko lagoon (northern Hokkaido, Japan) and Resolute Passage (Canadian High Arctic) was investigated. Chlorophyll concentration, bacterial concentration and microheterotrophy were compared at both sites. Bacterial acti...

Summary: | In spring of 1992, the microbial compartment at the base of first-year ice in Saroma Ko lagoon (northern Hokkaido, Japan) and Resolute Passage (Canadian High Arctic) was investigated. Chlorophyll concentration, bacterial concentration and microheterotrophy were compared at both sites. Bacterial activity and productivity were insufficient in both sites to satisfy the demand of microheterotrophs. Accordingly, a shift probably occurred in the grazing behavior of heterotrophic nanoprotozoans as the ice-algal bloom took place. |
