Development of protocols for cryopreservation microalgae Chlorococcum dissectum Korshikov and Dunaliella salina Teodoresco requires selection effective cryoprotectants their concentrations. One the stages choosing optimal concentrations is determining degree toxicity cells at equilibration stage. Solutions dimethyl sulfoxide, ethylene glycol, ethanol, glycerol (5–30%) modified PVS1 PVS2 (50 75%...

A longstanding challenge in stream ecology is to understand how landscape configuration organizes spatial patterns of ecosystem function via lateral groundwater connections. We combined laboratory bioassays and field additions a metabolic tracer (resazurin) test groundwater-stream confluences, or “discrete riparian inflow points” (DRIPs), regulate heterotrophic microbial activity along boreal s...
