... Hypercarbia Pangasius Bicarbonate The aquatic partial pressure of carbon dioxide ( P CO 2 ) in tropical river basins can be driven above 6 kPa daily by microbial respiration and organic decay ( Furch and Junk, 1997 ). These rapid elevations in P CO 2  exceed atmospheric levels by over 200...

We have previously shown that boar sperm motility is highly stimulated by bicarbonate, a naturally abundant component of oviductal fluid. Using...
