“…The information regarding temperature on marine invertebrates has not been well established. With regard to gastropods, few studies have been carried out (Pechenik 1984;Cheung and Lam 1995). Thus there is a need to study the influence of temperature on the toxicity induced by heavy metals to observe the variations brought about by changes in this physical parameter.…”

A study was conducted to determine the median lethal toxicity of four heavy metals on the marine gastropod Babylonia areolata. Median lethal toxicity tests were conducted to observe the sensitivity of this gastropod to metals and how variations in temperature might affect toxicity of test elements. Four heavy metals were used in the study. It was observed that the 96-hr LC 50 (in mg/L) for the different metals was found to be nickel (Ni) 33.53 (35.at room temperature 24 C. With temperature as a variable, median lethal concentration (LC 50 ) values were observed to increase from 22.41 mg/L at 10 C to 27.34 mg/L at 28 C and reduce to 18.43 mg/L at 30 C and a further rise in toxicity was observed at 35 C where LC 50 value was 12.7 mg/L as seen in the case of Zn. It was also observed that at 40 C thermal and chemical toxicity overlapped as 100% mortality was observed in controls. This trend was noted in all metals for Babylonia areolata indicating that temperature played an important role in determining LC 50 values of toxicants.

“…Salinity is a main factor influencing the distribution of aquatic organisms (Remane and Schlieper, 1971), including freshwater snail species, since it affects many of their physiological functions (Gainey and Greenberge, 1977;Jacobsen and Forbes, 1997). By contributing to increased metabolism it leads to physiological malfunction and, at high levels, mortality (Cheung and Lam, 1995). The soft tissues of snails have relatively high body water content, which leaves the tissues when exposed to high salinity due to osmotic pressure.…”

Abstract.Opisthorchis viverrini infection is associated with human cholangiocarcinoma and northeast Thailand has the highest incidence of this disease in the world. Bithynia siamensis goniomphalos is the major freshwater snail intermediate host of O. viverrini in this area and an analysis based on geographical information systems was used to determine the effect of variation in soil surface salt on the density and distribution of this snail. A malacological survey was carried out in 56 water bodies in the Khorat basin, northeast Thailand at locations with various soil surface salt levels. Mollusk samples were collected from 10 ecologically representative water body sites with 10-20 sampling stations in each. The shoreline of clear, shallow water bodies was found to be the preferred B. s. goniomphalos habitat. The snails were exclusively found in water with salinity levels ranging between 0.05 and 22.11 parts per thousand (ppt), which supports the notion that B. s. goniomphalos prefers water with some saline content over pure, freshwater. The highest snail population densities were in rice fields, ponds, road-side ditches and canals within a water salinity range of 2.5-5.0 ppt. However, the presence of B. s. goniomphalos was negatively correlated with water salinity (P ≤0.05), both with regard to density and distribution. The areas with the highest density of B. s. goniomphalos were those with less than 1% soil surface salt (potential index = 0.314), while the lowest densities were found in areas exceeding 50% soil surface salt (potential index = 0.015).

“…The metabolic increase was much more evident at lower salinities (25 and 30) than at 35, as reflected in the Q10 values (Table 2). Animals from temperate and subtropical waters are frequently less sensitive to this range of temperature variation, since a broad range of temperature-independent metabolic rates usually adjusts the organisms to the temperature window of their habitats (STICKLE;BAYNE, 1987;CHEUNG;LAM, 1995;PÖRTNER, 2001;EZGETA-BALI et al, 2011). Although B. gigantea can cope with a temperature increase from 0°C to 2.5°C with no change in energy requirement, the effects of an extra increase to 5°C always result in a higher energy expenditure, as is clearly represented in Figure 1.…”

OXYGEN CONSUMPTION AND AMMONIA EXCRETION OF THE ANTARCTIC AMPHIPOD Bovallia gigantea PFEFFER, 1888, AT DIFFERENT TEMPERATURES AND SALINITIES

A B S T R A C TThe energy budget of Antarctic stenothermic and/or stenohaline ectotherms is modulated by variations of temperature and salinity. The joint effects of these latter on polar organisms have been but little studied. Data on this subject are of great importance for an understanding of the energy demand of Antarctic animals such as amphipods, especially when considering their ecological importance and the possible impacts of global changes. Experiments were carried out at the Brazilian Antarctic Station "Comandante Ferraz" under controlled conditions. Specimens of Bovallia gigantea were collected in Admiralty Bay and acclimated to temperatures of 0°C; 2.5°C and 5°C and to salinities of 35, 30 and 25. Thirty measurements were taken for each of the nine possible combinations of the three temperatures and the three salinities. Metabolic rates were assessed based on oxygen consumption and total ammonia nitrogenous excretion in sealed respirometers. At 0°C and 2.5°C, the metabolic rates of the animals that were acclimated to salinities of 30 or 35 were similar, indicating a possible mechanism of metabolic independence of temperature. However, the metabolic rates were always higher at 5.0°C. The effects of temperature on oxygen consumption and on ammonia excretion rates were intensified by lower salinities. Individuals of B gigantea have a temperature-independent metabolic rate within a narrow temperature window that can be modified in accordance with salinity. R E S U M OO orçamento energético de animais ectotérmicos antárticos estenotérmicos e/ou estenohalinos é fortemente modulado pelas variações da temperatura e da salinidade. O efeito conjunto desses fatores em animais polares é pouco estudado. Dados sobre esse assunto são necessários para avaliar a demanda energética de organismos antárticos, como os anfípodes, principalmente devido a sua importância ecológica e aos possíveis impactos ocasionados por mudanças globais. Os experimentos foram realizados na Estação Antártica Brasileira "Comandante Ferraz", em condições controladas. Indivíduos de Bovallia gigantea coletados na Baía do Almirantado foram aclimatados às temperaturas de 0°C, 2,5°C e 5°C e às salinidades de 35, 30 e 25. Foram realizadas 30 medições para cada uma das nove combinações possíveis entre os fatores. Foram mensurados o consumo de oxigênio e a excreção de produtos nitrogenados, em câmaras respirométricas seladas. A 0°C e 2,5°C, as taxas metabólicas de indivíduos aclimatados às salinidades 30 ou 35 foram muito semelhantes, indicando um possível mecanismo de independência metabólica à temperatura. A 5,0°C, as taxas metabólicas foram sempre mais elevadas. Os efeitos da temperatura sobre as taxas de consumo de oxigênio e de excreção de produtos nitrogenados foram intensificados pela diminuição da salinidade. Indivíduos de B. gigantea apresentam independência térmica das taxas metabólicas em uma pequena janela de variação, que pode ainda ser modificada pela salinidade.
