PHOSPHORUS, NITROGEN AND THE GROWTH OF ALGAE IN LAKE KINNERET1
Journal of Phycology - Tập 11 Số 2 - Trang 155-162 - 1975

EVOLUTION OF MICROALGAE IN HIGHLY STRESSING ENVIRONMENTS: AN EXPERIMENTAL MODEL ANALYZING THE RAPID ADAPTATION OF DICTYOSPHAERIUM CHLORELLOIDES (CHLOROPHYCEAE) FROM SENSITIVITY TO RESISTANCE AGAINST 2,4,6‐TRINITROTOLUENE BY RARE PRESELECTIVE MUTATIONS1
Journal of Phycology - Tập 38 Số 6 - Trang 1074-1081 - 2002

The increasing rates of global extinction due to human activities necessitate studies of the ability of organisms to adapt to the new environmental conditions resulting from human disturbances. We investigated the evolutionary adaptation of a microalga to sudden environmental change resulting from exposure to novel toxic chemical residues. A laboratory strain of Dictyosphaerium chlorelloides (Naum... hiện toàn bộ
METAL‐INDUCED REACTIVE OXYGEN SPECIES PRODUCTION IN CHLAMYDOMONAS REINHARDTII (CHLOROPHYCEAE)1
Journal of Phycology - Tập 45 Số 2 - Trang 427-435 - 2009
Ilona Szivák, Renata Behra, Laura Sigg
Toxic effects of metals appear to be partly related to the production of reactive oxygen species (ROS), which can cause oxidative damage to cells. The ability of several redox active metals [Fe(III), Cu(II), Ag(I), Cr(III), Cr(VI)], nonredox active metals [Pb(II), Cd(II), Zn(II)], and the metalloid As(III) and As(V) to produce ROS at environmentally relevant metal concentrations was assessed.

THE ROLE OF REACTIVE OXYGEN SPECIES IN COPPER TOXICITY TO TWO FRESHWATER GREEN ALGAE1
Journal of Phycology - Tập 44 Số 2 - Trang 311-319 - 2008
Stefanie Knauert, Katja Knauer
The role of reactive oxygen species (ROS) in copper (Cu) toxicity to two freshwater green algal species, Pseudokirchneriella subcapitata (Korshikov) Hindák and Chlorella vulgaris Beij., was assessed to gain a better mechanistic understanding of this toxicity. Cu‐induced formation of ROS was investigated in the two algal species and linked to short‐term effects on photosynthetic activity and to lon... hiện toàn bộ
OPTICAL MONITORING AND FORECASTING SYSTEMS FOR HARMFUL ALGAL BLOOMS: POSSIBILITY OR PIPE DREAM?
Journal of Phycology - Tập 35 Số 6 - Trang 1477-1496 - 1999
Oscar Schofield, Joseph J. Grzymski, W. Paul Bissett, Gary J. Kirkpatrick, David F. Millie, Mark A. Moline, Collin S. Roesler
Monitoring programs for harmful algal blooms (HABs) are currently reactive and provide little or no means for advance warning. Given this, the development of algal forecasting systems would be of great use because they could guide traditional monitoring programs and provide a proactive means for responding to HABs. Forecasting systems will require near real‐time observational capabilities and hydr... hiện toàn bộ
Effect of temperature on photosynthesis‐light response and growth of four phytoplankton species isolated from a tidal freshwater river
Journal of Phycology - Tập 36 Số 1 - Trang 7-16 - 2000
James F. Coles, R. Christian Jones
Three cyanobacteria (Microcystis aeruginosaKütz. emend. Elenkin,Merismopedia tenuissimaLemmermann, andOscillatoriasp.) and one diatom (Aulacoseira granulatavar.angustissimaO. Mull. emend. Simonsen) were isolated from the tidal freshwater Potomac River and maintained at 23° C and 40 μmol photons·m−2·s−1on a 16:8 L:D cycle in unialgal culture. Photosynthetic parameters were determined in nutrient‐re... hiện toàn bộ
TEMPERATURE AND SALINITY EFFECTS ON GROWTH OF A NON‐CHAIN‐FORMING STRAIN OF FYMNODINIUM CATENATUM (DINOOHYCEAE) ESTABLISHED FROM A CYST FROM RECENT SEDIMENTS IN THE SOUND (øRESUND), DENMARK1
Journal of Phycology - Tập 29 Số 4 - Trang 418-426 - 1993
Marianne Ellegaard, Niels F. Christensen, Øjvind Meostrup
ABSTRACTThe athecate, marine dinoflagellate Gymnodinium catenatum Graham 1943 was cultured from a resting cyst found in sediment samples from The Sound, Denmark. Gymnodinium catenatum has not previously been registered alive in Danish waters, although fossilized cysts have been found in old sediments. The description (morphology and ultrastructure) of the strain established from the cyst complied ... hiện toàn bộ
GENETIC VARIATION AMONG STRAINS OF THE TOXIC DINOFLAGELLATE GYMNODINIUM CATENATUM (DINOPHYCEAE)
Journal of Phycology - Tập 35 Số 2 - Trang 356-367 - 1999
Christopher J. S. Bolch, Susan I. Blackburn, Gustaaf M. Hallegraeff, René E. Vaillancourt
The toxic dinoflagellate Gymnodinium catenatum Graham has formed recurrent toxic blooms in southeastern Tasmanian waters since its discovery in the area in 1986. Current evidence suggests that this species might have been introduced to Tasmania prior to 1973, possibly in cargo vessel ballast water carried from populations in Japan or Spain, followed by recent dispersal to mainland Australia.

RESTRICTION FRAGMENT LENGTH POLYMORPHISM OF RIBOSOMAL DNA INTERNAL TRANSCRIBED SPACER AND 5.8S REGIONS IN JAPANESE ALEXANDRIUM SPECIES (DINOPHYCEAE)1
Journal of Phycology - Tập 30 Số 5 - Trang 857-863 - 1994
Masao Adachi, Yoshihiko Sako, Yūzaburō Ishida
ABSTRACTThe 5.8S ribosomal RNA (rDNA) gene and flanking internal transcribed spacers (ITS1 and ITS2)from 9 isolates of Alexandrium catenella (Whedon and Kofoid) Taylor, 11 isolates of A. tamarense (Lebour) Taylor, and single isolates of A. affine (Inoue et Fukuyo) Balech, A. insuetum Balech, and A. pseudogonyaulax (Biecheler) Horiguchi ex Yuki et Fukuyo comb. nov. from various locations in Japan w... hiện toàn bộ
