The metabolic rates of five largemouth bass (Micropterus salmoides) were measured in flow-through respirometers under constant warm (30 °C), constant cool (15 °C), and diel cycles of warm and cool (20 h at 15 °C, 4 h at 30 °C) conditions. Metabolic rate for each individual did not differ significantly when tested under a diel temperature cycle or under constant conditions at that temperature. The metabolic rates were also similar to those predicted for standard metabolic rate from an earlier study. These data are interpreted in light of energetic modeling and vertical migration studies to predict that bass under predictably fluctuating temperature regimes react metabolically similar to bass acclimated to constant conditions at that temperature, and models constructed on data from laboratory-acclimated fish would not be substantially in error when used for fish under variable thermal conditions.

The Relationship

In a recent study examining the relationship between longevity and metabolism in a large number of recombinant inbred Drosophila melanogaster lines, we found no indication of the inverse relationship between longevity and metabolic rate that one would expect under the classical “rate of living” model. A potential limitation in generalizing from that study is that it was conducted on experimental material derived from a single set of parental strains originally developed over 20 years ago. To determine whether the observations made with those lines are characteristic of the species, we studied metabolic rates and longevities in a second, independently derived set of recombinant inbred lines. We found no correlation in these lines between metabolic rate and longevity, indicating that the ability to both maintain a normal metabolic rate and have extended longevity may apply to D. melanogaster in general. To determine how closely our measurements reflect metabolic rates of flies maintained under conditions of life span assays, we used long-term, flow-through metabolic rate measurements and closed system respirometry to examine the effects of variables such as time of day, feeding state, fly density, mobility of the flies, and nitrogen knockout on D. melanogaster metabolic rate. We found that CO2 production estimated in individual flies accurately reflects metabolic rates of flies under the conditions used for longevity assays.

Preferred Body Temperature

Pythons have standard metabolic rates and preferred body temperatures that are lower than those of most other reptiles. This study investigated metabolic rates and preferred body temperatures of seven taxa of Australian pythons. We found that Australian pythons have particularly low metabolic rates when compared with other boid snakes, and that the metabolic rates of the pythons did not change either seasonally or on a daily cycle. Preferred body temperatures do vary seasonally in some species but not in others. Across all species and seasons, the preferred body temperature range was only 4.9˚C. The thermal sensitivity (Q10) of oxygen consumption by pythons conformed to the established range of between 2 and 3. Allometric equations for the pooled python data at each of the experimental temperatures gave an equation exponent of 0.72–0.76, which is similar to previously reported values. By having low preferred body temperatures and low metabolic rates, pythons appear to be able to conserve energy while still maintaining a vigilant ‘sit and wait’ predatory existence. These physiological attributes would allow pythons to maximise the time they can spend ‘sitting and waiting’ in the pursuit of prey.

Species Specific

Understanding how rising temperatures, ocean acidification, and hypoxia affect the performance of coastal fishes is essential to predicting species-specific responses to climate change. Although a population’s habitat influences physiological performance, little work has explicitly examined the multi-stressor responses of species from habitats differing in natural variability. Here, clearnose skate (Rostaraja eglanteria) and summer flounder (Paralichthys dentatus) from mid-Atlantic estuaries, and thorny skate (Amblyraja radiata) from the Gulf of Maine, were acutely exposed to current and projected temperatures (20, 24, or 28 °C; 22 or 30 °C; and 9, 13, or 15 °C, respectively) and acidification conditions (pH 7.8 or 7.4). We tested metabolic rates and hypoxia tolerance using intermittent-flow respirometry. All three species exhibited increases in standard metabolic rate under an 8 °C temperature increase (Q10 of 1.71, 1.07, and 2.56, respectively), although this was most pronounced in the thorny skate. At the lowest test temperature and under the low pH treatment, all three species exhibited significant increases in standard metabolic rate (44–105%; p < 0.05) and decreases in hypoxia tolerance (60–84% increases in critical oxygen pressure; p < 0.05). This study demonstrates the interactive effects of increasing temperature and changing ocean carbonate chemistry are species-specific, the implications of which should be considered within the context of habitat.

Samples of largemouth bass were collected from Par Pond located on the Energy Research and Development Administration's Savannah River Plant in Aiken, South Carolina, from June 1972 to May 1973 inclusive. The sampling stations reflected water temperatures which were both normal and greater than 10°C above normal for the area. The acanthocephalanNeoechinorhynchus cylindratuswas the dominant species found in the bass sampled. Incidences of infection for this parasite were generally greater than 95% regardless of location. A pronounced seasonal cycling pattern in the intensity of infection was noted in both thermal regions. Significant differences, however, in the mean density ofN. cylindratusper host in fish taken from the heated area as compared with unheated areas were noted.Turnover in the acanthocephalan population was measured by following the percentage of individuals less than 2 mm long. Fall proved to be the most intense parasite recruitment season, followed by maturation of the parasite and subsequent loss from the fish host.The principal factors responsible for the seasonal incidence and intensity patterns are considered to be changes in the fish feeding behaviour and annual temperature regimes.

Abstract. Standard metabolic rate is a major functional trait with large inter-individual variability in many groups of aquatic species. Here we present results of an experimental study to address variation in standard metabolic rates, over different scales of organisation and environments, within a specific group of aquatic macro-invertebrates (i.e. gammarid amphipods) that represent the primary consumers in detritus food webs. The study was carried out using flow-through microrespirometric techniques on male specimens of three gammarid species from freshwater, transitional water and marine ecosystems. We examined individual metabolic rate variations at three scales: (1) at the individual level, during an 8 h period of daylight; (2) at the within-population level, along body-size and body-condition gradients; (3) at the interspecific level, across species occurring in the field in the three different categories of aquatic ecosystems, from freshwater to marine. We show that standard metabolic rates vary significantly at all three scales examined, with the highest variation observed at the within-population level. Variation in individual standard metabolic rates during the daylight hours was generally low (coefficient of variation, CV<10 %) and unrelated to time. The average within-population CV ranged between 30.0 % and 35.0 %, with body size representing a significant source of overall inter-individual variation in the three species and individual body condition exerting only a marginal influence. In all species, the allometric equations were not as steep as would be expected from the 3∕4 power law, with significant variation in mass-specific metabolic rates among populations. The population from the transitional water ecosystem had the highest mass-specific metabolic rates and the lowest within-population variation. In the gammarid species studied here, body-size-independent variations in standard individual metabolic rates were higher than those explained by allometric body size scaling, and the costs of adaptation to short-term periodic variations in water salinity in the studied ecosystems also seemed to represent a major source of variation.

Standard Metabolism

Ten years research on metabolic rates and swimming speeds of sockeye salmon (Oncorhynchus nerka) ranging in weight from 2 to 2000 g, at temperatures from 2 to 24 C, is reviewed and summarized. Analysis of weight–slope relations (b values) at three temperatures, using log–log transformations, provided an overall mean of 0.88 for standard metabolism and 0.99 for active metabolism. A previously determined semilog equation for temperature effect on standard metabolic rate (at approximately 50 g) was supported by supplementary data at 2 C. Predictive graphic models in the form of isopleths of metabolic rates and critical swimming speeds in relation to weight, length, and temperature are depicted. These provide a composite presentation useful in estimating the metabolic rate and maximum sustained speed for any size and temperature.

Per Se

Standard metabolic rate (VO2 STD) was determined for three species of passerine bird from the family Meliphagidae to investigate the possible effect of nectarivory on standard metabolic rate in this family. The three species that we investigated did not show a significant departure from allometric predictions of standard metabolic rate for passerine species. Disparities between standard metabolic rate for meliphagids in the present study and previous data appear to reflect methodological differences, and no general allometric relationship is apparent for meliphagids at present. In meliphagids, nectarivory per se is not an important correlate with standard metabolic rate. Data from additional meliphagid species, collected under standardised conditions, are required to confirm the generality of the findings of the present study, that nectarivorous meliphagids have a standard metabolic rate typical of passerine birds.

Rate Of Oxygen Consumption

Multiple regression analyses of previously published data were performed to describe the effect of variations in body mass (M, in grams) and temperature (t, in degrees Celsius) on the rate of oxygen consumption ([Formula: see text], in millilitres O2 per gram per hour). For homeotherms and poikilotherms, the resultant equations describing standard metabolic rate are [Formula: see text] and [Formula: see text], respectively. The metabolic rate of unicells was described by [Formula: see text], although the temperature term was not statistically significant. When solved at 39 °C, the homeotherm equation is essentially similar to previously published relations. At 20 °C, the poikilotherm relation is slightly higher, and the unicell relation considerably lower, than Hemmingsen's widely cited relations. Enough data were available to provide a statistical description of active reptiles and fish: [Formula: see text]; this relationship may be used to approximate the metabolic rate of actively foraging fish and reptiles. Equations for the standard metabolic rate can serve as components in the calculation of minimal metabolic rates of homeotherms and higher poikilotherms in nature; such values could then be increased by estimates of the additional demands associated with movement, feeding, growth, etc. For unicells and lower vertebrates, standard rates also serve as estimates of free-living rates.

Maximum Metabolic Rate

The metabolic rate of aquatic animals is closely related to oxygen concentration and influenced by internal and external factors. Despite its high value as marine fish species in South Korea, information on rock bream Oplegnathus fasciatus metabolism is scarcely available. This study observed the standard metabolic rate (SMR), routine metabolic rate (RMR), and active metabolic rate (AMR) of rock bream Oplegnathus fasciatus subjected to different temperature settings. Another observation was performed to find out the maximum metabolic rate (MMR) on rock bream subjected to different salinity settings. Fish (TL: 26.86 ± 0.29 cm and BW: 469.40 ± 38.21 g for SMR, RMR, and AMR measurement; TL: 26.7 ± 0.4 cm and BW: 451.0 ± 44.4 g for MMR measurement) were observed using respirometer (dimension = 30 cm × 20 cm × 20 cm; volume: 10.4 L) inside a recirculation systems. SMR, RMR, and AMR were measured at 15°C, 20°C, and 25°C. Meanwhile, MMR was measured at 15, 25, and 35 psu. The results showed that SMR, RMR, and AMR increased linearly by increasing the temperatures (SMR: 58.7 ± 3.2, 102.7 ± 4.3, and 157.1 ± 4.1 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively; RMR: 66.0 ± 8.6, 112.6 ± 10.2, and 175.2 ± 21.3 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively; AMR: 73.4 ± 7.4, 122.0 ± 6.3, and 196.7 ± 15.4 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively), whilst MMR decreased by lowering salinity (48.5 ± 5.2, 61.1 ± 5.5, and 89.3 ± 14.7 mg O2/kg/hour at salinity of 15, 25, and 35 psu, respectively).
