“…Although not widespread, the presence of this type of metabolic regulation has been suggested for C. trivittatus (this study) and for Neomysis (A. W. Knight, personal communication) and reported for the vertically mi-grating cladoceran, Leptodera (Moshiri et al 1969). The presence of metabolic adaptations to decrease the effect of high temperature on respiration rate would tend to make it less costly to move up into warm water.…”

One of the recent theories for the adaptive value of vertical migration states that migrants gain an energetic advantage over nonmigrants because by alternating between areas of high and low temperatures they are able to partition energy into growth more efficiently than nonmigrants. The energetics of the vertical migration of fourth—instar Chaoborus trivittatus larva in Eunice Lake, British Columbia was studied to identify and quantify this hypothesized energetic advantage. Fourth—instar C. trivittatus larvae undergo a regular, synchronous, diel vertical migration which exposes them to a wide range of temperature and prey density. Feeding occurs primarily at night and near the surface. Although all zooplankton in Eunice Lake are potential prey, Diaptomus kenai constitutes the majority of the biomass in the diet of fourth—instar larvae; Carbon assimilation efficiency of both copepods and cladocerans by C. trivittaus is ° 68%. Respiration rate increases linearly with temperature over the range 5—25 degrees C, although there is a suggestion of a plateau in O_2 consumption over the temperature range to which the larvae are exposed during migration. Temperature and ration size interacted to determine larval growth rate; fluctuating temperatures limited growth regardless of prey density while at constant high temperature prey density limited the growth rate. Analysis of several possible migration strategies showed that on an energetics basis alone growth will be maximized by either staying near the surface where there is food, or by vertically migrating with a physiologically determined periodicity based on individual feeding history. Laboratory growth experiments and the results of computer simulations of vertical migration show that the energetic hypothesis for the adaptive value of vertical migration does not hold for C. trivittatus larvae in Eunice Lake. These larvae do not follow either of the migration strategies that is energetically most efficient. No alternative hypothesis to explain their migration pattern is attractive. Possibly it is maintained by immigration from populations exposed to strong selection for this behavior pattern.

Multiple regression analysis of published zooplankton filtering and feeding rates yielded separate regression equations for cladocerans, marine Calanoid copepods, and all zooplankton. Ingestion rate was found to increase significantly with animal size, food concentration, and temperature. Filtering rate also increased with animal size and temperature, but declined as food concentration increased. The analysis suggests a difference in particle size preference between cladocerans and copepods. Experimental conditions such as crowding and duration also significantly affected filtering and feeding rates. The regression models allow examination of differences and similarities among zooplankton taxa, functional response, particle size selection, energy allocation, and threshold food concentration. The statistical models describe suspension feeding more precisely than either average literature values or verbal descriptions of trend. The results also suggest possible mechanisms of feeding limitation and provide a heuristic framework for the design of experimental analyses of zooplankton feeding in marine and freshwater systems.

“…As pointed o u t by WINBERG (1976) metabolic levels can only be compared analytically on the basis of an evaluation of the A parameter values if the magnitudes of the coefficients I% are equal or a t least close. The values of I% are also known t o be extremely variable under similar experimental conditions for numerous reasons including differences in the physiological conditions of individuals from different age groups (THORSEN, 1952), retention time in the laboratory prior to experiment (RAZOULS 1972; MORGAN and WILDER, 1936;MOSHIRI et al, 1969; and others), insignificant, but often hardly perceptible, procedural deviations during tests (WINBERG, 1976), and a too small number of samples and narrow size range of observations (VILENKIN, 1966; IVLEVA, 1973 b). In the last case, the coefficient I% may vary due to the higher activity of large individuals since it is known that activity is essentially not only a function of temperature, but also of body mass (IVLEVA, 1963).…”

The respiratorion rates of Crustacea from temperate and tropical waters of the Atlantic Ocean were measured directly at habitat temperatures of 19, 25 and 29 O C . The results were analysed together with data obtained from similar investigations in previous years (IVLEVA, 1977) on Crustacea from moderately cold and polar latitudes at 10, 6 and 0 O C . Variations of the valuea for A and L in generalized regressions (R=AWE) for Crustacea within the temperature limits of the physiological range were shown to have quite a clear-cut and regular character. The coefficient k varied from 0.60 to 0.79 and revealed a tendency to increase as temperatures decreased.The value of A increased with rising temperature within all intervals from 0 to 30 OC. The quantitative relationship between respiration rate and temperature was evaluated by the Arrhenius equation. Statistical processing of resultant data indicated a rather close association between log A and the habitat temperature of the Crustacea but only slight deviations from the theory of empirically found values. The accelerating effect of temperature (p) was 13 k0.13 kcal/mol. This value was used to calculate Qi0, which was more convenient for practical purposes. I. V.

Vertical temperature distribution was extremely variable (KHLYSTOV and BELYAKOVA, 1975. In the central Atlantic (stations 2163-2168) the temperature had already dropped by 3-6 "C at a depth of only 50 m; closer to the 100 and 200 m horizons, the temperature had dropped by 5-8 and 11-15 O C , respectively (Fig. 2C). A different thermal stratification pattern was noticed in the Gulf of Guinea (Fig. 2B), where abrupt temperature drops (by 13-15 O C ) occured within the top 100 m horizon, the thermocline layer being a t a depth of 30-35 m.i I Figure 2.
