| Description
| - Daphnia galeata je tradičně považována za nemigrující druh, který žije v teplém epilimniu. Hloubkové segregace a vertikální migrace jsou obvykle spojovány s jinými druhy, a to D. hyalina, nebo D. longispina. Naše dvouletá studie na nádrži Římov (Česká Republika) ukazuje, že většina populace D. galeata žije v létě v teplém epilimniu, nicméně někteří jedinci obývají rovněž hluboké vrtvy. Tato hypolimnetická subpoluce obývá trvale studené hypolimnium a nemigruje. Elektroforézou allozymů jsme prokázali, že hypolimnetická subpopulace je geneticky diferenciovaná od populace v epilimniu. Tato genetická diferenciace je pravděpodobně výsledkem kombinace různých hloubkových preferencí rozličných klonálních linií D. galeata a rozdílných selekčních tlaků v obou odlišných vrstvách. (cs)
- Daphnia galeata is traditionally regarded to be a non-migratory species, which lives in warm epilimnetic waters. Depth segregation or vertical migration is usually attributed to other Daphnia species such as D. hyalina or D. longispina. In a two-year study, we found that in a deep, dammed-valley reservoir (Římov Reservoir, Czechia) the majority of the population of D. galeata lives in the warm epilimnetic waters during the summer months, but some specimens of this species could be always found in the deep strata as well. This hypolimnetic subpopulation stays in the cold hypolimnetic water and does not migrate. Using allozyme electrophoresis, we found that the subpopulation from the deep hypolimnion was clearly genetically differentiated from the population in the epilimnion. The genetic differentiation is likely the result of both the different depth preferences of various D. galeata clones and different selective pressures.
