Abstract
Life on tidal coasts presents physiological major challenges for sessile species. Fluctuations in oxygen and temperature can affect bioenergetics and modulate metabolism and redox balance, but their combined effects are not well understood. We investigated the effects of intermittent hypoxia (12h/12h) in combination with different temperature regimes (normal (15 °C), elevated (30 °C) and fluctuating (15 °C water/30 °C air)) on the Pacific oyster Crassostrea (Magallana) gigas. Fluctuating temperature led to energetic costly metabolic rearrangements and accumulation of proteins in oyster tissues. Elevated temperature led to high (60%) mortality and oxidative damage in survivors. Normal temperature had no major negative effects but caused metabolic shifts. Our study shows high plasticity of oyster metabolism in response to oxygen and temperature fluctuations and indicates that metabolic adjustments to oxygen deficiency are strongly modulated by the ambient temperature. Co-exposure to constant elevated temperature and intermittent hypoxia demonstrates the limits of this adaptive metabolic plasticity.

Effects of different oxygen regimes on ecological performance and bioenergetics of a coastal marine bioturbator, the soft shell clam Mya arenaria. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 860:160459.

Abstract
Benthic species are exposed to oxygen fluctuations that can affect their performance and survival. Physiological effects and ecological consequences of fluctuating oxygen are not well understood in marine bioturbators such as the soft-shell clam Mya arenaria. We explored the effects of different oxygen regimes (21 days of exposure to constant hypoxia (~4.1 kPa PO2), cyclic hypoxia (~2.1-~10.4 kPa PO2) or normoxia (~21 kPa PO2)) on energy metabolism, oxidative stress and ecological behaviors (bioirrigation and bioturbation) of M. arenaria. Constant hypoxia and post-hypoxic recovery in cyclic hypoxia led to oxidative injury of proteins and lipids, respectively. Clams acclimated to constant hypoxia maintained aerobic capacity similar to the normoxic clams. In contrast, clams acclimated to cyclic hypoxia suppressed aerobic metabolism and activated anaerobiosis during hypoxia, and strongly upregulated aerobic metabolism during recovery. Constant hypoxia led to decreased lipid content, whereas in cyclic hypoxia proteins and glycogen accumulated during recovery and were broken down during the hypoxic phase. Digging of clams was impaired by constant and cyclic hypoxia, and bioirrigation was also suppressed under constant hypoxia. Overall, cyclic hypoxia appears less stressful for M. arenaria due to the metabolic flexibility that ensures recovery during reoxygenation and mitigates the negative effects of hypoxia, whereas constant hypoxia leads to depletion of energy reserves and impairs ecological functions of M. arenaria potentially leading to negative ecological consequences in benthic ecosystems.

Abstract
Hypoxia in freshwater ecosystems is spreading as a consequence of global change, including pollution and eutrophication. In the Patagonian Andes, a decline in precipitation causes reduced lake water volumes and stagnant conditions that limit oxygen transport and exacerbate hypoxia below the upper mixed layer. We analyzed the molecular and biochemical response of the North Patagonian bivalve Diplodon chilensis after 10 days of experimental anoxia (<0.2 mg O2/L), hypoxia (2 mg O2/L), and normoxia (9 mg O2/L). Specifically, we investigated the expression of an alternative oxidase (AOX) pathway assumed to shortcut the regular mitochondrial electron transport system (ETS) during metabolic rate depression (MRD) in hypoxia-tolerant invertebrates. Whereas, the AOX system was strongly upregulated during anoxia in gills, ETS activities and energy mobilization decreased [less transcription of glycogen phosphorylase (GlyP) and succinate dehydrogenase (SDH) in gills and mantle]. Accumulation of succinate and induction of malate dehydrogenase (MDH) activity could indicate activation of anaerobic mitochondrial pathways to support anoxic survival in D. chilensis. Oxidative stress [protein carbonylation, glutathione peroxidase (GPx) expression] and apoptotic intensity (caspase 3/7 activity) decreased, whereas an unfolded protein response (HSP90) was induced under anoxia. This is the first clear evidence of the concerted regulation of the AOX and ETS genes in a hypoxia-tolerant freshwater bivalve and yet another example that exposure to hypoxia and anoxia is not necessarily accompanied by oxidative stress in hypoxia-tolerant mollusks.

Abstract
Organic sediments in aquatic ecosystems are well known sinks for nutrients, silicon, and metal(loid)s. Organic matter-consuming organisms like invertebrate shredders, grazers, and bioturbators significantly affect element fixation or remobilization by changing redox conditions or binding properties of organic sediments. Little is known about the effect of filter feeders, like the zebra mussel Dreissena polymorpha, an invasive organism in North American and European freshwater ecosystems. A laboratory batch experiment exposing D. polymorpha (∼1200 organisms per m2) to organic sediment from a site contaminated with arsenic, copper, lead, and uranium revealed a significant uptake and accumulation of arsenic, copper, iron, and especially uranium both into the soft body tissues and the seashell. This is in line with previous observations of metal(loid) accumulation from biomonitoring studies. Regarding its environmental impact, D. polymorpha significantly contributed to mobilization of silicon, iron, phosphorus, arsenic, and copper and to immobilization of uranium (p < 0.001), probably driven by redox conditions, microbial activity within the gut system, or active control of element homeostasis. No net mobilization or immobilization was observed for zinc and lead, because of their low mobility at the prevailing pH of 7.5-8.5. The present results suggest that D. polymorpha can both ameliorate (nutrient mobilization, immobilization of toxicants mobile under oxic conditions) or aggravate negative effects (mobilization of toxicants mobile under reducing conditions) in ecosystems. Relating the results of the present study to observed population densities in natural freshwater ecosystems suggests a significant influence of D. polymorpha on element cycling and needs to be considered in future studies.

Abstract
We used (1)H nuclear magnetic resonance spectroscopy to describe key metabolites of the polar metabolome of the freshwater mussel, Elliptio complanata. Principal components analysis documented variability across tissue types and river of origin in mussels collected from two rivers in North Carolina (USA). Muscle, digestive gland, mantle and gill tissues yielded identifiable but overlapping metabolic profiles. Variation in digestive gland metabolic profiles between the two mussel collection sites was characterized by differences in mono- and disaccharides. Variation in mantle tissue metabolomes appeared to be associated with sex. Nuclear magnetic resonance spectroscopy is a sensitive means to detect metabolites in the tissues of E. complanata and holds promise as a tool for the investigation of freshwater mussel health and physiology.

Abstract
This study examined the metabolic responses of the limpet Patella caerulea (L.) to anoxia and dehydration, attempting to tease apart the effect of these two stressful conditions, which are often not clearly distinguished in experiments. Specimens were exposed to: (a) oxygen-free sea water; (b) oxygen-saturated water (controls); (c) low-humidity air (55% RH); and (d) high-humidity air (100% RH). For each of the treatments, we took samples of five specimens after 6 and 18 h of exposure to the experimental conditions and determined the concentrations in the foot muscle of succinate, acetate, propionate, aspartate and alanine. Exposure to anoxia caused an increase in the levels of succinate (6 and 18 h) and acetate and propionate (18 h) with respect to control specimens. Anoxia also induced a decrease of aspartate and an increase of alanine after both 6 and 18 h. Exposure to both moist and dry air generally had negligible effects on the organic acid levels. Aspartate content increased after 18 h of exposure to moist air. Alanine levels also increased with respect to control values after exposure to air, with dry air having the more pronounced effect. In conclusion, the results of this study suggest that one should be cautious when inferring anaerobic conditions from the simple exposure of intertidal species to air, without strict control of the experimental conditions and actual respiration rates.

Abstract
Tauropine dehydrogenase (tauropine:NAD oxidoreductase) was purified from the shell adductor muscle of the ormer, Haliotis lamellosa. The enzyme was found to utilize stoichiometrically NADH as co-enzyme and pyruvate and taurine as substrates producing tauropine [rhodoic acid; N-(D-1-carboxyethyl)-taurine]. The enzyme was purified to a specific activity of 463 units/mg protein using a combination of ammonium sulphate fractionation, ion-exchange and affinity chromatography. The relative molecular mass was 38,000 +/- 1000 when assessed by gel filtration on Ultrogel AcA 54 and 42,000 +/- 150 by electrophoresis on 5-10% polyacrylamide gels in the presence of 1% sodium dodecyl sulphate; the data suggest a monomeric structure. Tauropine and pyruvate were found to be the preferred substrates. Among the amino acids tested for activity with the enzyme, only alanine is used as an alternative substrate, but with a rate less than 6% of the enzyme activity with taurine. Of the oxo acids tested, 2-oxobutyrate and 2-oxovalerate were also found to be substrates. Apparent Km values for the substrates NADH, pyruvate and taurine are 0.022 +/- 0.003 mM, 0.64 +/- 0.07 mM and 64.7 +/- 5.4 mM, respectively, at pH 7.0 and for the products, NAD+ and tauropine, are 0.29 +/- 0.01 mM and 9.04 +/- 1.27 mM, respectively, at pH 8.3. Apparent Km values for both pyruvate and taurine decrease with increasing co-substrate (taurine or pyruvate) concentration. NAD+ and tauropine were found to be product inhibitors of the forward reaction. NAD+ was a competitive inhibitor of NADH, whereas tauropine gave a mixed type of inhibition with respect to pyruvate and taurine. Succinate was found to inhibit non-competitively with respect to taurine and pyruvate with an apparent Ki value in the physiological range of this anaerobic end product. The inhibition by L-lactate, not an end product in the ormer, was competitive with respect to pyruvate. The physiological role or tauropine dehydrogenase during anaerobiosis is discussed.

Abstract
1. Octopine dehydrogenase and lactate dehydrogenase were purified 190-fold and 10-fold respectively from the adductor muscle of the marine bivalve Cardium edule by gel filtration on Sephadex G-100 and chromatography on DEAE-Sephadex A-50. 2. Lactate dehydrogenase was capable to convert D- and L-lactate, had a molecular weight of about 70 000 and 280 000 daltons, exhibits no distinct pH optimum and was not inhibited by lactate. The enzyme showed apparent Km values of 0.16 mM for pyruvate and 16 mM and 48 mM for D- and L-lactate respectively. 3. In comparison to the purified enzymes from other species, octopine dehydrogenase from Cardium edule showed similar biochemical properties : pH optima of 6.8 and 8.7 respectively, Km values of 0.9 mM (for pyruvate) and 2.0 mM (for arginine), a molecular weight of 37 000 daltons and inhibition by octopine. Electrophoretic studies on standard polyacrylamide gels showed five isoenzymes. 4. The biochemical properties of both dehydrogenases are compared to the conditions in vivo of these animals and the biological role of the octopine dehydrogenase is discussed.

Abstract
1. Concentrations of glycogen and of key metabolites have been measured in Cardium edule during aerobic and anaerobic incubation. 2. After 15 hours of anoxia only a slight carbohydrate consumption was found in the whole animal, whereas a decrease in glycogen level seemed evident in the separated adductor muscle. 3. The main end products of the anaerobic carbohydrate breakdown are succinate and alanine which account for 40% and 30% respectively of all accumulated compounds. 4. The concentrations of L-lactate and octopine also increase after 15 hours anaerobic condition, but both are only of minor importance as end products. 5. Propionate is not detectable in the control groups, but accumulates a little during anaerobiosis. The two possible reasons for this low production have been discussed.
