3], Secchi, total suspended solids (TSS), and biomass of cryptophytes
(Bcry) were slightly negatively skewed, while specific conductivity (Cond) and number of species (Nsp) were slightly positively skewed.
Erken zooplankton prefer to eat small chrysophytes and cryptophytes
, while small green algae with a thick cellulose shell are consumed in markedly smaller amounts.
The first cluster included small cryptophytes
from the X2-group that occurred mostly in spring and early summer.
Analysis of carotenoid alloxanthin allows for the distinguishing of the relative importance of cryptophytes
The majority of taxa associated with Ageratina luciae-brauniae and/or Solidago albopilosa are phanerophytes (40%) or hemicryptophytes (36%); 2% are chamaephytes, 13% are cryptophytes
, and 9% are therophytes.
25%, chamaephytes (in ferns, herbaceous plants with perennating buds on aerial branches of less than 50 cm height) = 10%, and cryptophytes
(buds are below the soil surface) = 1.
The rest was taken up by cryptophytes
, mainly Cryptomonas spp.
Cyanobacteria, Euglenophytes, Chrysophytes and Cryptophytes
were present at the three sampling sites.
Samples for phytoplankton species composition and enumeration were fixed with Lugol, and the dominating groups were identified as diatoms, cryptophytes
, and flagellates and monads less than 5 [micro]m, in accordance with the sedimentation method of Utermohl (1931).
They also found cyanobacteria, chrysophytes and cryptophytes
were dominant at times while dinoflagellates, chlorophytes and euglenoids appeared occasionally abundant, but were relatively minor components on an annual basis.
The presence of cryptophytes
and hemicryptophytes was the result of heavy grazing pressure that led the plants to reproduce and regenerate mostly through underground parts, irrespective of the climatic conditions acting there upon.
Hemiselmis virescens and Plagioselmis prolonga gave a negative relationship with TP and DIP and a positive relationship with temperature.
