| Description | ’n Oorsig word gegee van apparatuur en tegnieke wat gebruik word om die suurstofverbruikskoers (MO₂) van terrestriële en akwatiese invertebrate te meet. Die manometriese metode (veral konstante drukrespirometrie) is in die verlede baie gebruik om MO₂ by invertebrate te meet. Tans word hierdie metode nog steeds suksesvol gebruik vir veral invertebrate wat kleiner as 1 mg in lewende massa is. Die meer resente elektrochemiese metodes bied die voordeel dat metings oor baie langer tye kan geskied, omdat die apparatuur makliker geoutomatiseerd gemaak kan word. Dit het veral die metings van MO₂ by akwatiese diere baie bevorder. Hiervoor is die polarografiese suurstofsensor gebruik. Met die onlangse uitvinding van die sirkoniumsuurstofsensor kon ook noukeurige metings van die MO₂ van groter terrestriele invertebrate met die hulp van hier die elektrochemiese apparatuur verkry word. A review is presented of the apparatus and techniques used to determine the oxygen consumption rate (MO₂) of terrestrial and aquatic invertebrates. The classic manometric method (especially constant pressure respirometry) has been extensively used in the past to measure MO₂. At present this method is still being used with success for small invertebrates weighing less than 1 mg in live weight. The more modern electrochemical techniques have the advantage that measurements can be made over longer time intervals because these instruments are better suited to automation. MO₂ measurements were first performed on aquatic animals with polarographic oxygen sensors. After the invention of the zirkonium oxygen sensor it is now possible to make accurate measurements of MO₂ on bigger terrestrial invertebrates. | |
