The combined information from the flow signal and patchy odor signal influences the mechanisms that guide the plankter to the source.
where T = total number of plankters counted, A = area of grid in [mm.sup.2], N = number of grids employed, and 1,000 = area of counting chamber in [mm.sup.2] (Boyd [18]).
This dichotomy has been attributed to the unique potential of marine plankters for distant dispersal across homogenous oceans with few barriers to gene flow (2).
Influence of food density on respiration rate of two crustacean plankters, Daphnia galeata and Bosmina longirostris.
Also imaged were a variety of invertebrate plankters, ranging from copepods and larvaceans to ctenophores and medusae to invertebrate larval types, such as echinoderm pluteus.
Flow information may be restricted to situations in which animals shed more intense fluid disturbances, as when some plankters transiently achieve velocities of several hundred body lengths per second (Yen and Strickler, 1996), and reach a fluid regime that is transitional between laminar and turbulent flow.
Additionally, a 73- [micro]m mesh net with a mouth area of 0.014 [m.sup.2] was nested inside the Tucker trawl in 1992 to collect microzooplankton simultaneously with all other plankters. The displaced volume of the microzooplankton was included in the total standardized plankton volume for each sampling day.
