“…1 is similar to that reported for various other aquatic animals [8], [34], [35]. To evaluate the applicability of this relationship to A. tonsa , we used analogous respiration rates ( ARR ) derived from A. tonsa egg production, somatic growth, and ingestion rates measured in four separate studies ([16], [18], [24] and the present study), as well as direct A. tonsa respiration rate measurements from 12 studies ([20], [30] and 10 studies reviewed in [29]).…”

Predicting the Effects of Coastal Hypoxia on Vital Rates of the Planktonic Copepod Acartia tonsa Dana

We describe a model predicting the effects of low environmental oxygen on vital rates (egg production, somatic growth, and mortality) of the coastal planktonic copepod Acartia tonsa. Hypoxic conditions can result in respiration rate being directly limited by oxygen availability. We hypothesized that A. tonsa egg production, somatic growth, and ingestion rates would all respond in a similar manner to low oxygen conditions, as a result of oxygen dependent changes in respiration rate. Rate data for A. tonsa egg production, somatic growth, and ingestion under low environmental oxygen were compiled from the literature and from supplementary experiments. The response of these rates to oxygen was compared by converting all to the analogous units in terms of oxygen utilization, which we termed analogous respiration rate. These analogous respiration rates, along with published measurements of respiration rates, were used to parameterize and evaluate the relationship between A. tonsa respiration rate and environmental oxygen. At 18°C, our results suggest that A. tonsa experiences sub-lethal effects of hypoxia below an oxygen partial pressure of 8.1 kPa (∼3.1 mg L−1 = 2.3 mL L−1). The results of this study can be used to predict the effects of hypoxia on A. tonsa growth and mortality as related to environmental temperature and oxygen partial pressure. Such predictions will be useful as a way to incorporate the effects of coastal hypoxia into population, community, or ecosystem level models that include A. tonsa. This approach can also be used to characterize the effects of hypoxia on other aquatic organisms.

“…The metabolic rates of epipelagic species are often stimulated by hydrostatic pressures greater than those which they normally encounter (George 198 1). However, studies on a variety of vertically migrating and deeper living pelagic species have indicated that temperature is usually the more critical factor and that these animals show little response of metabolic rates to pressures within the species' normal ranges (Teal 197 1;Smith and Teal 1973;Belman and Gordon 1979;Torres and Childress 1983). In some cases, midwater species do seem to vary their activity and metabolic rates as a function of pressure (Teal 197 1;Childress 1977a;Mickel and Childress 1982); however, the effects do not appear to be typical of most species and are usually modest in magnitude.…”

This study addresses the effect of hydrostatic pressure on the metabolic rates of six species of deep‐living (∼500–1,500‐m typical depths) gelatinous zooplankton (three chaetognaths, two hydromedusans, and one polychaete). Metabolic rates were measured at 5°C and the hydrostatic pressure equivalent to that at either 0‐(0.101 MPa) or 1,000‐m depth (10.1 MPa). O2 consumption rate vs. wet weight relationships at the two pressures were compared by ANCOVA for each species separately. Five of the species studied (the chaetognaths and medusans) showed no significant difference in slope or elevation in these relationships, indicating there was no significant effect of hydrostatic pressure on the metabolic rates of these species under the experimental conditions. The metabolic rate relationships of the sixth species, Poeobius meseres, were significantly different in slope, but the lines intersected within the weight range studied so the metabolic rates were not different overall. These data support the validity of measuring the metabolic rates of such species at surface pressures and indicate that metabolic rates of deeper living gelatinous species are relatively insensitive to hydrostatic pressure.

“…Although the compositions of these organisms changed with depth (Childress and Nygaard, 1973), this accounted for little of the decline. Metabolic rates measured in studies of many different species have been confirmed by more detailed laboratory studies on particular species (for example: Belman and Gordon, 1979;Childress, 1971a;Childress, 1977a;Gordon et ai., 1976;Hiller-Adams and Childress, 1983a;Meek and Childress, 1973;Mickel and Childress, 1982a;Quetin and Childress, 1976;Torres and Childress, 1983;Torres and Childress, 1985) and in situ (Smith, 1982;Smith, 1985;Smith and Laver, 1981). The pattern of metabolic rate declining with depth to a greater extent than explained by temperature has also been found for midwater fishes off California (Torres et al, 1979) and midwater crustaceans off Hawaii (Cowles et al, 1991).…”
