- The osmorespiratory compromise in the euryhaline killifish: water regulation during hypoxia
Summary: During acute hypoxia, the euryhaline killifish increases ventilation and decreases heart rate, gill diffusive water flux, paracellular permeability and drinking rate, but incurs a salinity-dependent net water balance penalty.
- Aquatic acidification: a mechanism underpinning maintained oxygen transport and performance in fish experiencing elevated carbon dioxide conditions
Summary: Root effect haemoglobins and plasma-accessible carbonic anhydrase may be responsible for the ability of fishes to maintain oxygen transport during high PCO2 conditions.
- Ammonia-independent sodium uptake mediated by Na+ channels and NHEs in the freshwater ribbon leech Nephelopsis obscura
Summary: Novel mechanisms for Na+ uptake in the skin of the freshwater leech Nephelopsis obscura were identified to employ both Na+/H+ exchangers and Na+ channels, while also being independent of ammonia transport.
- Stress and food deprivation: linking physiological state to migration success in a teleost fish
Summary: Individual energetic state appears to dictate future life-history strategy whereas an artificial stressor impairs growth and reduces survival regardless of life-history strategy.
- Consequences of calcium decline on the embryogenesis and life history of Daphnia magna
Summary: Ambient calcium is declining in thousands of soft-water lake habitats. Daphnia females provision their offspring with calcium and through that incur a potential allocation trade-off.
