Viral mortality of the marine alga Emiliania huxleyi (Haptophyceae) and termination of algal blooms
The possible roles of viruses in phytoplankton dynamics were investigated in seawater mesocosms with natural assemblages of phytoplankton growing under various nutrient regimes. Blooms of the marineExpand

VIRUS PRODUCTION IN PHAEOCYSTIS POUCHETII AND ITS RELATION TO HOST CELL GROWTH AND NUTRITION
In this experimental study we investigated how growth conditions and physiological status of the marine haptophyte Phaeocystjs pouchetii affect its interaction with the lytic virus PpVO1. A simpleExpand

Flow cytometric analysis of phytoplankton viability following viral infection
Two flow cytometric assays using physiological probes were used on the phytoplankton species Phaeocystis pouchetii and Micromonas pusilla to examine the assays' utility in detecting viral infections.Expand

Viral lysis of Phaeocystis pouchetii and bacterial secondary production
In this experimental study we investigated the effect of viral infection on primary production and carbon flow in a phytoplankton-DOC-bacteria food chain during viral lysis of the phytoplanktonExpand

Stable coexistence in marine algal host-virus systems
All microalgal host-virus systems isolated to date are lytic: the viruses lyse the infected hosts within hours after infection. Moreover, current models of phytoplankton host-virus interactionsExpand

Effects of ultraviolet radiation on marine virus-phytoplankton interactions.
Abstract Ambient ultraviolet radiation (UVR) is harmful to many biological systems and increased UVR, due to a reduced ozone layer, may have many unforeseen consequences. Viruses are the mostExpand

FLOW CYTOMETRIC ANALYSES OF VIRAL INFECTION IN TWO MARINE PHYTOPLANKTON SPECIES, MICROMONAS PUSILLA (PRASINOPHYCEAE) AND PHAEOCYSTIS POUCHETII (PRYMNESIOPHYCEAE)
Cell characteristics of two axenic marine phytoplankton species, Micromonas pusilla (Butscher) Manton et Parke and Phaeocystis pouchetii (Hariot) Lagerheim, were followed during viral infection usingExpand

Viral activity in relation to Emiliania huxleyi blooms: a mechanism of DMSP release?
The role of viral activity with respect to bloom dynamics and production of dissolved dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS) was investigated in Norwegian coastal waters and inExpand

ISOLATION AND CHARACTERIZATION OF A VIRUS INFECTING PHAEOCYSTIS POUCHETII (PRYMNESIOPHYCEAE) 1
A virus infecting the haptophyte Phaeocystis pouchetii (Hariot) Lagerheim was isolated from Norwegian coastal waters in May 1995 at the end of a bloom of this phytoplankter. The virus was specificExpand

Elevated production of dimethylsulfide resulting from viral infection of cultures of Phaeocystis pouchetii
The effects of viral lysis on dimethyl sulfide (DMS) and particulate and dissolved dimethylsulfoniopropionate (DMSP) concentrations were studied in batch cultures of Phaeocystis pouchetii infectedExpand
