Differentiation of surface properties of chlorococcalean algae by means of aqueous two phase systems

open access: yesActa Societatis Botanicorum Poloniae, 2014
Algal cells belonging to various strains of Chlorococcales (Chlorophyta) have been partitioned in aqueous two-phase systems containing ionogenic polymers, DEAE-dextran or SDS-dextran, at various pH values.

The fossil recordand evolution of freshwater plants: A review [PDF]

open access: yesGeologica Acta, 2003
Palaeobotany applied to freshwater plants is an emerging field of palaeontology. Hydrophytic plants reveal evolutionary trends of their own, clearly distinct from those of the terrestrial and marine flora.

Phytoplankton from Duas Bocas Reservoir, Espírito Santo State, Brazil (except diatoms)

open access: yesHoehnea
Duas Bocas is a small water supply reservoir (0.51 km²) located in a forested area (Duas Bocas Biological Reserve) (20º18'S and 40º28'W). Phytoplankton community was investigated by samplings weekly taken in the dry (July, 1998) and rainy (March 1999 ...

Ecology and evolution of competitive trait variation in natural phytoplankton communities under selection

open access: yesEcology Letters, Volume 25, Issue 11, Page 2397-2409, November 2022., 2022
Natural phytoplankton communities were subjected to three types of resource limitation (nitrogen, phosphorus, light) in outdoor mesocosms and 21 strains were isolated to quantify responses to selection of R* for these resources in the lab. R*s of phytoplankton can be good predictors of responses to resource limitation in natural communities, though ...

Beyond nitrogen: phosphorus – estimating the minimum niche dimensionality for resource competition between phytoplankton

open access: yesEcology Letters, Volume 24, Issue 4, Page 761-771, April 2021., 2021
We tested predicted species biomass from monocultures against observations in two‐species mixtures. Although uptake rates were similar across species, following the classic Redfield ratio, we found that model accuracy was maximised around three to five resources, including resources such as Fe, Mg, Na and S, and that models that included only N and P ...
