| improved method for determining bacterial filtration rates in zooplankton. | filtration rates were determined for a natural population of zooplankton grazers (bosmina longirostris [müll.], cyclops vicinus vicinus [ulianine], acanthodiaptomus denticornis [wierz.], and daphnia longispina [müll.]) by using h-labeled bacteria as food for these organisms. there was a relationship between filtration rates of the major zooplankton grazers and the prevailing algal and bacterial composition in the lake water. low filtration rates were obtained in the presence of colonial and fila ... | 1988 | 16347724 |
| changes in selection regime cause loss of phenotypic plasticity in planktonic freshwater copepods. | rapid phenotypic adaptation is critical for populations facing environmental changes and can be facilitated by phenotypic plasticity in the selected traits. whereas recurrent environmental fluctuations can favour the maintenance or de novo evolution of plasticity, strong selection is hypothesized to decrease plasticity or even fix the trait (genetic assimilation). despite advances in the theoretical understanding of the impact of plasticity on diversification processes, comparatively little empi ... | 2014 | 24587186 |
