are at the whim of these complex flow patterns.
At the outset, copepods
from different locations showed wide variability in heat tolerance.
In their analysis of the Mexican freshwater copepod
fauna, Suarez-Morales and Reid (1998) noted that states and subregions with arid climates may reveal a surprising diversity and provide models for studying dispersal mechanisms and island biogeography.
The Longitudinal distribution of copepods
in Corumba Reservoir, state of Goias, Brazil.
The total body length of adult copepods
was measured from the beginning of the cephalothorax to the end of the caudal rami, without taking into account the caudal setae.
is nudging close, a clutch of shrink-wrapped eggs
34) determined that copepods
were deposited in small depressions in a similar manner to passive particles and could not select areas in environments with moving water.
Unlike the copepod
trends, the rotifer trends closely resembled the total zooplankton treatment trends.
Cladocerans and copepods
were identified to species while rotifers were identified to genus.
The winter plankton include fewer bacteria and cyanobacteria, and the grazers are largely represented by crustaceans (especially the copepod
Diaptomus: Pace and Orcutt, 1981).
abundance peaked between March and April, but abundances rarely exceeded 30 individuals [L.
Of the large species, microcrustaceans called `cladocerans' and `copepods
' (see boxed story) were well represented, particularly the huge four millimetre `calanoid' copepod
, Boeckella major.
