... dissolved oxygen (DO) control. All tested control systems created the desired DO conditions with high accuracy and repeatability across trials. The resources provided shown here can be adapted and modified to be used in a variety of experimental contexts. Arduino boards (Arduino LLC, Monza, Italy) were...

... aquatic environment. Despite natural fluctuations in dissolved oxygen levels, all aquatic systems, from shallow freshwater environments to the deep ocean, are affected by the increasing frequency of hypoxic events and prevalence of prolonged, more severe hypoxia ( Breitburg et al., 2018 ; Diaz...

...Kerri Lynn Ackerly; Rüdiger Krahe; Christopher P. Sanford; Lauren J. Chapman ABSTRACT Low dissolved oxygen (hypoxia) can severely limit fish performance, especially aerobically expensive behaviours including swimming and acquisition of sensory information. Fishes can reduce oxygen requirements...

...Mark W. L. Morris; Miki Hondzo SUMMARY Laboratory measurements of dissolved oxygen (DO) uptake by Glossosoma nigrior Banks were conducted in a sealed, recirculating flume under variable fluid flow velocities. Measurements were performed in similar water temperatures, DO concentrations and fluid...

...I. G. Priede; J. F. DE L. G. Solbé; J. E. Nott ABSTRACT In natural waters the dissolved oxygen concentration can vary considerably both spatially and temporally in rivers ( Solbé, 1988 ), lakes ( Gnaiger, 1983 ), coral reefs ( Griffith et al . 1987 ) and the thermocline in the open ocean ( Dizon et...
