“…and Cryptomonas marssonii showed quite similar patterns, but the diel vertical distribution patterns of these two species were not synchronized during the study. These two species clearly showed upward migration Wood 1976;Cloern 1977;Jones and Ilmavirta 1978;Heaney and Eppley 1981;Arvola 1984;Salonen et al 1984;Arvola et al 1987;Jones 1988). Generally, a distinct migration was not observed except in the second investigation on April 9, during which C. marssonii exhibited a slight upward migration pattern in the morning.…”

“…Most previous studies on the diel vertical distribution and migration of phytoflagellates have reported that it might be a direct response to changing light intensity, temperature, nutrient condition and a complex interaction of these factors (George and Heaney 1978;Heaney and Talling 1980;Heaney and Epply 1981;Salonen et al 1984). Moreover, the vertical distribution of phytoplankton may be affected by their horizontal patchness or herbivore grazing (Heaney 1976;Lehman and Sandgren 1985;Arvola et al 1987;Jones 1988), and may be ccontrolled by endogenous rhythms (circadian) (Sournia 1974;Weiler and Karl 1979;Heaney and Furnass 1980;Frempong 1984).…”

“…Recently, many studies have been carried out to elucidate the effects of variable environmental factors in controlling the vertical distribution and migration of phytoflagellates. There was increasing evidence that the vertical distribution and diel migration of phytoflagellates was caused by such as light intensity (Tilzer 1973;Georgeand Heaney 1978) and nutrients (Cloern 1977;Sommer 1982;Salonen et al 1984) or both (Heaney and Eppley 1981;Arvola et al 1987). Additionally, it may be caused by zooplankton grazing (Arvola 1984;Arvola et al 1987;Jones 1988) and endogenous rhythms (circadian) (Sournia 1974;Weiler and Karl 1979;Heaney and Furnass 1980;Frempong 1984).…”

However, a generalization of the vertical migration patterns of phytoflagellates has not been available for yet because the vertical distribution patterns appears to be involved complicated interactions between variable external factors with species.…”

Diel vertical distribution of phytoflagellates and interactions between the phytoplankton components and environmental and biological factors were studied in a small artificial pond for three days on the December 18, 1998 and April 9 to 10, 1999. The phytoplankton population was dominated by Mallomonas akrokomos of chrysophytes and Cryptomonas marssonii and Chroomonas sp. of cryptophytes. The vertical distribution of these phytoflagellates taxa exhibited clear diel migration pattern. Moreover their migration patterns are showed differential fluctuation between M. akrokomos, C. marssonii and Chroomonas sp. The later two species upward migrated in the evening as well as night, whereas the former species migrated downward. Their distinctive migration pattern was found during the night but was not observed in the morning. During daytime C. marssonii and Chroomonas sp. showed maximum density above 2 m depth but M. akrokomos below 2 m depth. The diel vertical distribution of the dominant phytoflagellates did not show significant correlation between physical, chemical and biotic factors.

Diel Variations in the Vertical Distribution of Crustacean Zooplankton and Food Selection by Planktivorous Fish in a Shallow Turbid Lake

The variations in the vertical migrations by zooplankton and food composition of fish in the shallow, clay-turbid Mustionselkä basin of Lake Hiidenvesi were studied (water depth 3 m). Daphnids showed signs of reverse migration, their density in the surface layer being highest during the day. The reverse migration was probably due to predation threat by the predatory cladoceran Leptodora kindtii. Chydorus sphaericus, which was consumed especially by the day active bleak (Alburnus alburnus), showed normal vertical migration. Copepods showed no clear vertical movements. Leptodora kindtii, as well as the large herbivore Limnosida frontosa, showed no vertical migrations, but their overall abundance increased considerably during the night, indicating horizontal movement towards the open water at night. Due to the shallowness of the water, vertical migrations may not be a good predator-avoidance strategy for the largest cladocerans, which may be able to perform horizontal migrations.
