Guerrero, Ricardo Generalitat de Catalunya 14 pages, 9 figures Cryptomonas phaseolus was present throughout the water column during holomixis in Lake Ciso (Spain), despite the presence of sulfide. During stratification, C. phaseolus formed a layer with abundances up to lo5 cells ml- I at the metalimnion, where oxygen and sulfide were present simultaneously at low concentrations. Light at this depth was between 1 and 20% of surface incident radiation. Loss factors were studied during 2 years. Outwash was negligible most of the year, but could reach 30% of total losses during certain short periods in winter. Cryptomonas phaseolus was found to sink with speeds up to 55 cm d-l, which is in accord with velocities calculated with Stokes' law. There was a single sedimentation peak in spring accounting for 40-60% of total losses. Decomposition was the most important loss factor for most of the year. Cryptomonas phaseolus cells were always actively growing, but losses balanced production for most of the study period. Average cell volume increased during mixing and decreased during stratification. Doubling times were minimal (7 d) in March at the onset of stratification and slowly increased through spring and summer, reaching a maximum just before mixing (around 50 d) and decreasing again through winter until the next March minimum This work was supported by a grant from the Comision Asesora Cientifica y Tecnica, Spain. C. P.-A. was a recipient of an “Ajut a la Recerca” from the Generalitat de Catalunya Peer Reviewed 2019-01-03T12:49:17Z 2019-01-03T12:49:17Z 1987-03 2019-01-03T12:49:17Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.4319/lo.1987.32.2.0285 issn: 0024-3590 Limnology and Oceanography 32(2): 285-298 (1987) http://hdl.handle.net/10261/173737 10.4319/lo.1987.32.2.0285 http://dx.doi.org/10.13039/501100002809 Publisher's version https://doi.org/10.4319/lo.1987.32.2.0285 No open Association for the Sciences of Limnology and Oceanography |
