“…In essence, it is the key biological rate on which all other processes depend. Metabolic theory predicts that the metabolic rate of a species scales with body mass by a 3 4 power-law [14] and scales exponentially with temperature [9,13]. This theory also proposes similar allometrically scaled relationships for a range of biological processes, including consumption rate, mortality rate and ontogenetic growth [13].…”

Understanding and predicting the consequences of warming for complex ecosystems and indeed individual species remains a major ecological challenge. Here, we investigated the effect of increased seawater temperatures on the metabolic and consumption rates of five distinct marine species. The experimental species reflected different trophic positions within a typical benthic East Atlantic food web, and included a herbivorous gastropod, a scavenging decapod, a predatory echinoderm, a decapod and a benthic-feeding fish. We examined the metabolism -body mass and consumption -body mass scaling for each species, and assessed changes in their consumption efficiencies. Our results indicate that body mass and temperature effects on metabolism were inconsistent across species and that some species were unable to meet metabolic demand at higher temperatures, thus highlighting the vulnerability of individual species to warming. While body size explains a large proportion of the variation in species' physiological responses to warming, it is clear that idiosyncratic species responses, irrespective of body size, complicate predictions of population and ecosystem level response to future scenarios of climate change.

“…At salinity 25 mechanisms of metabolic thermal compensation seem not to operate properly. It is known that salinity variations can produce significant changes in the energy demands of polar and non-polar ectotherms, including parasites (MÖLLER, 1978;ALLAN et al, 2006;FILIPPOV, 2006). Species adapted to broad variations of environmental factors, such as the temperate shrimp Palaemon peringuery, for instance, did not show any significant differences in oxygen consumption when data measured at the same temperature over a salinity range of 15 to 35 were compared (ALLAN et al, 2006).…”

“…Salinity, however, although generally stable, can be modified temporarily in coastal regions by melting ice (SZAFRANSKI;LIPSKI, 1982). When temperature is studied in conjunction with salinity variations, the importance of temperature changes can be even better understood and reveal important shifts in energy demand (ROCHA et al, 2001;ALLAN et al, 2006;FILIPPOV, 2006). In addition, laboratory investigations can also improve our comprehension of the homeostatic abilities to modulate processes according to the degree of temperature and salinity variations.…”

Metabolic rates of the antarctic amphipod Gondogeneia antarctica at different temperatures and salinities

A B S T R A C TChanges in environmental factors may deeply affect the energy budget of Antarctic organisms as many of them are stenothermal and/or stenohaline ectotherms. In this context, the aim of this study is to contribute to knowledge on variations in the energy demand of the Antarctic amphipod, Gondogeneia antarctica as a function of temperature and salinity. Experiments were held at the Brazilian Antarctic Station "Comandante Ferraz", under controlled conditions. Animals collected at Admiralty Bay were acclimated to temperatures of 0°C; 2.5°C and 5°C and to salinities of 35, 30 and 25. Thirty measurements were made for each of the nine combinations of the three temperatures and three salinities, totalling 270 measurements. Metabolic rates were assessed by oxygen consumption and total nitrogenous ammonia excretion, in sealed respirometers. When acclimated to salinities 30 or 35, metabolic rates at 0°C and 2.5°C were very similar indicating a possible mechanism of metabolic compensation for temperature. At 5.0°C, however, metabolic rates were always higher. Lower salinities enhanced the effects of temperature on metabolism and ammonia excretion rates. The physiological adaptations of individuals of G. antarctica suggest adaptive mechanisms for energy saving, adjusted to an environment with stable conditions of temperature and salinity. Little is known about the joint effects of salinity and temperature and this study is an important contribution to the understanding of the mechanism of polar organisms in their adaptation to both factors. R E S U M OAlterações ambientais podem modificar a alocação de energia dos organismos, principalmente dos ectotermos estenotérmicos e/ou estenohalinos. Nesse contexto, este trabalho contribui com o conhecimento da demanda de energia do anfípode antártico Gondogeneia antarctica em função da temperatura e da salinidade. Experimentos foram realizados na Estação Antártica Brasileira "Comandante Ferraz", em condições laboratoriais controladas. Animais coletados na Baía do Almirantado foram aclimatados a temperaturas de 0°C; 2.5°C e 5°C e salinidades de 35, 30 and 25. Foram realizadas trinta medições para cada uma das nove combinações das três temperaturas com as três salinidades, totalizando 270 medições. As taxas metabólicas foram estimadas por meio do consumo de oxigênio e excreção de amônia, em câmaras respirométricas seladas. Quando aclimatados a salinidades 30 ou 35, as taxas metabólicas a 0°C e 2.5°C foram semelhantes indicando possível mecanismo de compensação térmica, nessa faixa de variação dos fatores. A 5.0°C, no entanto, as taxas metabólicas foram sempre mais elevadas. Baixas salinidades potencializaram os efeitos da temperatura no consumo de oxigênio e na excreção de produtos nitrogenados. Os resultados estão relacionados a mecanismos adaptativos para economia de energia em indivíduos G. antarctica, ajustados a um ambiente que tem condições estáveis de temperatura e de salinidade. Pouco se sabe sobre os efeitos conjugados da salinidade e temperatura nos organismos e...

This study investigated short-term effects of temperature on survival, body weight and the fatty acid profile of farmed marine polychaete Perinereis helleri-an excellent live feed maturation diet for penaeid shrimp broodstock. Two consecutive experiments were conducted to evaluate the effects of low temperature (4, 8, 12, 16 and 20 • C) and high temperature (20, 24, 28, 32 and 36 • C) on a 7-month-old population of P. helleri farmed at Bribie Island Research Centre, Australia. The experimental polychaetes were purged for 24 h at 20 • C before being transferred directly into 500 ml glass chambers, sealed and submersed in different target temperature water baths. The jars were then kept for 3 or 6 h in the low-temperature experiment and 1 or 3 h in the hightemperature experiment, respectively. Results showed that mortality occurred only at 4 • C and 8 • C (p < 0.01). Weight loss occurred across all treatments of the lowtemperature experiment, but only at 36 • C in the high-temperature one. Analysis of lipid classes and fatty acids show that farmed P. helleri is rich in polyunsaturated fatty acids (PUFA, i.e. 37% of total fatty acids), especially arachidonic acid (ARA,.The total value of essential fatty acids was 15.8% of total fatty acids or 16.8 mg/g dry matter. The n-3:n-6 ratio was 1.07 ± 0.04. This study suggests that P. helleri can be transported at ambient temperature of 16-20 • C and can be farmed in a tropical climate.
