Substantial oxygen consumption by aerobic nitrite oxidation in oceanic oxygen minimum zones

Nature Communications, 2021
Oxygen is fundamental for marine life, yet it is absent from large areas of the ocean. Here the authors demonstrate that microbial nitrite oxidation effectively consumes oxygen where oxygen concentrations are low, playing a pivotal role in these regions.

Comparison of methods for measuring oxygen consumption rate of Hyriopsis cumingii

浙江大学学报. 农业与生命科学版, 2013
Oxygen consumption rate is an important physiological indicator for evaluating the environmental adaptation of bivalves. Generally, oxygen consumption rate of bivalve is measured with closed respirometry or flow-through respirometry.

Variation in the link between oxygen consumption and ATP production, and its relevance for animal performance

Proceedings of the Royal Society B: Biological Sciences, 2015
It is often assumed that an animal's metabolic rate can be estimated through measuring the whole-organism oxygen consumption rate. However, oxygen consumption alone is unlikely to be a sufficient marker of energy metabolism in many situations.

Influence of Oxygen Consumption on Pregnancy Rates of Hanwoo Calves following Embryo Transfer

Journal of Animal Reproduction and Biotechnology, 2014
Recently, several approaches have been used to measure the oxygen consumption rates of individual embryos, but relationship between oxygen consumption and pregnancy rates of Hanwoo following embryo transfer has not yet been reported.

Respiration Rates of Individual Bovine In Vivo-Produced Embryos Measured with a Novel, Scanning Electrochemical Microscopy

Journal of Animal Reproduction and Biotechnology, 2014
Oxygen consumption is a useful parameter for evaluating mammalian embryo quality, since individual bovine embryos was noninvasively quantified by scanning electrochemical microscopy (SECM).

Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow [PDF]

, 2011
The heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was

Plastron respiration using commercial fabrics [PDF]

, 2014
A variety of insect and arachnid species are able to remain submerged in water indefinitely using plastron respiration. A plastron is a surface-retained film of air produced by surface morphology that acts as an oxygen-carbon dioxide exchange surface ...
