Vertical distribution of pelagial zooplankton in a middle-sized dimictic
The measurements of vertical temperature profiles revealed summer stratification and periods of turnover in the spring and fall indicating that the reservoir is a warm dimictic
water body (Fig.
Juusa is a eutrophic dimictic
lake, with strong stratification during spring-summer.
Relationship between plant roots and benthic animals in three sediment types of a dimictic
Gull Lake is 33 m deep, dimictic
, oligo-mesotrophic, characterized by low zooplanktivory (Leibold and Tesier 1991, Tessier and Leibold 1997), and strong resource limitation of the Daphnia populations (Hu and Tessier 1995).
These diagrams show the existence of the three basic annual heat cycles, the basis for classification into dimictic
, monomictic, and amictic lakes.
Lake Paajarvi is a medium-sized, deep, dimictic
, humic and mesotrophic lake (Fig.
Patterns in algal recruitment from sediment to water in a dimictic
, eutrophic lake.
All study lakes are dimictic
, oligotrophic, relatively deep lakes (maximum depth ranges 24-117 m) located on the Canadian shield.
The lakes are dimictic
(total circulation in spring and autumn).
Although coexisting species of zooplankton typically differ in vertical habitat use or diel vertical migration behavior (Makarewicz and Likens 1975), experimental studies of competition in zooplankton have rarely employed enclosures deep enough to mimic the full range of depth habitats available in a natural, dimictic
