...Cosima S. Porteus; Christina C. Roggatz; Zelia Velez; Jörg D. Hardege; Peter C. Hubbard ABSTRACT In the past decade, many studies have investigated the effects of low pH/high CO 2 as a proxy for ocean acidification on olfactory-mediated behaviours of marine organisms. The effects of ocean...

... (RBC CA) activity limits the rate of intracellular acidification, yet its role in O 2 delivery has been downplayed. We developed an in vitro assay to manipulate RBC CA activity while measuring Hb-O 2 offloading following a physiologically relevant CO 2 -induced acidification. RBC CA activity in red...

...Kelly D. Hannan; Jodie L. Rummer ABSTRACT Aquatic acidification, caused by elevating levels of atmospheric carbon dioxide (CO 2 ), is increasing in both freshwater and marine ecosystems worldwide. However, few studies have examined how acidification will affect oxygen (O 2 ) transport...

... still remain unclear. In the present study, we show that future predictions of ocean warming (+4°C) and acidification (ΔpH=0.5 units) may compromise the development of early life stages of a highly commercial teleost fish, Solea senegalensis . Exposure to future conditions caused a decline in hatching...

... the endocytotic pathway that retrieves proteins from the glomerular ultrafiltrate requires V-ATPase-dependent acidification of post-endocytotic vesicles. The regulation of both of these activities depends upon the ability of cells to monitor the pH and/or bicarbonate content of their extracellular environment...

...Joseph A. Covi; Steven C. Hand SUMMARY Under anoxia, Artemia franciscana embryos downregulate metabolic processes and approach an ametabolic state. Entrance into this quiescent state is accompanied by a profound acidification of the intracellular space, and more than two decades of research now...

...HONG LIN; D. J. RANDALL Acidification of expired water was studied in rainbow trout exposed to water of pH9.91, 6.80 (control) and 3.88. For the high-pH and the control exposures, the water flowing over the gills was acidified because of the dominant effect of CO 2 hydration. During the low-pH...

Mortality was observed within 24 h at pH5 and especially at pH4. The main reason for the high sensitivity of lampreys to acid water...
