In the quantitative zooplankton samples from the pelagial
of Lake Peipsi, 57 species of cladocerans and 28 species of copepods were found, in which the characteristic species of oligo-mesotrophic and eutrophic waters co-dominated.
Linking denitrifier community structure and prevalent biogeochemical parameters in the pelagial
of the central Baltic Proper (Baltic Sea).
The cladoceran Hyocryptus, the copepod Paracyclops and ostracod were occasional dwellers of the pelagial
. The most abundant group were the Copepods of the genus Thermocyclops sp., followed by the cladoceran Daphnia sp., Two species of Daphnia were observed: Daphnia laevis, which was the most abundant and Daphnia gessneri, with much lower density.
Trophic structure in the pelagial
of 25 shallow New Zealand lakes: changes along nutrient and fish gradients.
The results of physicochemical analyses of pelagial
surface water performed during the vegetation season (month-to-month data, from April to October) evidenced that Lake Jasne was characterized by high transparency and low values of nutrient concentrations, typical for mesotrophic, moderately hard water ecosystems (Table 1).
Aphanizomenon has prevailed mainly in August-September; however, a maximum level of biomass was recorded in the late July of 1991: 250 g[m.sup.-3] in the pelagial
zone of the central part of L.
Diacyclops abyssicola and Mesocyclops leuckarti occur in littoral as well as in pelagial
, Thermocyclops crassus and T.
The basic material was collected monthly from the pelagial
of the Estonian part of L.
Este litoral no esta aislado en ningun momento de la influencia pelagial
. Ambiente lentico.
It indicates the wide range of historical and literary allusions contained in the story's text--throughout the story Dowell used terms from Thomson's Science of Life (1899), including littoral, abyssal, and pelagial
. Literary allusions include the "retreating sound of the tide across the shingle" (186), which refers to the loss of faith in Dover Beach; a quote from Piers Plowman, Life of Do-well (15) (Dowell's "signature"); and a mention of "seventy fountains" (183) taken from Agathocles.
Food and habitat partitioning among juveniles of three fish species in the pelagial
of a mesotrophic lake.
