SUMMARY Daphnia are highly sensitive to sodium metabolism disruption caused by aquatic acidification and ionoregulatory toxicants, due to their finely balanced ion homeostasis. Nine different water chemistries of varying pH (4, 6 and 8) and calcium concentration (0, 0.5 and 1 mmol l–1) were used to delineate the mechanism of sodium influx in Daphnia magna. Lowering water pH severely inhibited sodium influx when calcium concentration was high, but transport kinetic analysis revealed a stimulated… Expand
The Disruption of Daphnia magna Sodium Metabolism by Humic Substances: Mechanism of Action and Effect of Humic Substance Source
TLDR
The mechanism by which humic substances perturb sodium metabolism in a freshwater invertebrate, the water flea Daphnia magna, is investigated, suggesting that impacts on sodium metabolism may be limited to commercially available humic materials. Expand
Sodium uptake in different life stages of crustaceans: the water flea Daphnia magna Strauss
TLDR
Differential sensitivity of neonates and adults to iono- and osmoregulatory toxicants, such as metals, are discussed with respect to differences in whole-body Na+ uptake kinetics, as well as in the mechanisms of Na+ transport involved in the whole- body Na+. Expand
Acute physiological responses of the freshwater snail Elimia flava (Mollusca: Pleuroceridae) to environmental pH and calcium.
TLDR
The results suggest that snails exposed to pH 4 cease interacting with the surrounding medium and use internal stores of CaCO(3) to buffer hemolymph acidification, whereas snails at pH 5 and higher appear to use environmental calcium as a buffer source. Expand
Physiological responses of Daphnia pulex to acid stress
TLDR
Chronic exposure to acidic conditions had a pervasive impact on Daphnia's physiology including acid-base balance, extracellular PCO2, circulation and ventilation, and energy metabolism, and the activation of defense mechanisms which may result from gene-expression mediated adjustments in hemolymph buffer proteins and in epithelial properties.

Ocean acidification: synergistic inhibitory effects of protons and heavy metals on 45Ca uptake by lobster branchiostegite membrane vesicles
TLDR
Analysis of the relative inhibitory effects of increased proton or heavy metal interaction with 45Ca2+ uptake suggests that divalent metals may reduce the calcium transport about twice as much as a drop in pH, but together, they appear to abolish carrier-mediated transport. Expand
The influence of dissolved organic matter (DOM) on sodium regulation and nitrogenous waste excretion in the zebrafish (Danio rerio)
TLDR
Dissolved organic materials, ubiquitous but often overlooked components of natural waters, have profound effects on the ionoregulatory physiology of zebrafish, effects that depend on properties of these heterogeneous substances. Expand
Multiple functions of the crustacean gill: osmotic/ionic regulation, acid-base balance, ammonia excretion, and bioaccumulation of toxic metals
TLDR
This review provides a comprehensive overview of the ecology, physiology, biochemistry, and molecular biology of the mechanisms of osmotic and ionic regulation performed by the gill. Expand

TLDR
Four freshwater taxa groups are compared, to investigate similarities and differences in ion transport processes and what ion transport mechanisms suggest about the toxicity of these or other ions in freshwater. Expand
Interactive effects of copper and calcium in Daphnia pulex
TLDR
The data show that both calcium decline and copper increase in aquatic ecosystems may negatively impact natural Daphnia populations, and that interactions between these two metals may occur in natural environments that result in fitness consequences for zooplankton. Expand
The effect of dissolved organic matter (DOM) on sodium transport and nitrogenous waste excretion of the freshwater cladoceran (Daphnia magna) at circumneutral and low pH.
TLDR
Widespread reductions in ammonia and urea excretion rates may be attributed partially to the higher buffering capacities of natural DOM sources, as well as their ability to interact with biological membranes as estimated by a new measure calculated from their acid-base titration characteristics, the Proton Binding Index (PBI).

Effect of low pH on sodium regulation in two species of Daphnia
TLDR
The net loss of sodium in soft water was due to both an increase in sodium outflux and a decrease in sodium influx, while in hard water the effect was primarily on sodium out flux. Expand

Adult rainbow trout, acclimated to external calcium concentrations ranging from 60–5700 μequiv/1, were exposed to pH 4.0-4.1 for 44 h. Initially, this exposure provoked massive net losses of sodiumExpand
Humic Substances Influence Sodium Metabolism in the Freshwater Crustacean Daphnia magna
TLDR
Environmentally realistic levels of Suwannee River natural organic matter and Aldrich humic acid significantly enhanced sodium transport and significantly promoted the unidirectional loss of sodium from the daphnids to the water, an effect not observed in the presence of AHA. Expand

Mechanism of acute silver toxicity in Daphnia magna.

The results clearly demonstrate that the key mechanism involved in acute Ag+ toxicity in D. magna, the most sensitive freshwater organism tested to date, resembles that described for freshwater fish--that is, inhibition of active sodium uptake by blockade of Na+,K(+)-ATPase. Expand

Positive net Na+ and Cl− balance resulted from partial inhibition of influx components; effluxes were little affected and flux effects were reversed during 5 d of recovery at pH = 7.5. Expand
