Summary
1. The principles involved in the design of an electrolytic respirometer are set out.
2. A respirometer is described for air-breathing animals which allows the continuous recording over long periods (up to two weeks) of oxygen consumption at rates of the order of 10-100 µl. per hour.
3. Provision is made for maintaining the temperature, pressure, and carbon dioxide and oxygen levels constant and at atmospheric values.
4. A new design of recorder displays the results directly as rate of oxygen consumption.
5. The features of the apparatus are discussed with reference to specific requirements.

Read & Publish participation continues to grow
“It is particularly encouraging for early career researchers, as it allows them to display their research globally without the need to find costs to cover the open access option.”
Professor Fernando Montealegre-Z (University of Lincoln) shares his experience of publishing Open Access as part of our growing Read & Publish initiative. We now have over 150 institutions in 15 countries and four library consortia taking part – find out more and view our full list of participating institutions.
Nocturnal reef residents have deep-sea-like eyes
Fanny de Busserolles and colleagues from The University of Queensland have discovered that the eyes of nocturnal reef fish have multibank retinas, layers of photoreceptors, similar to the eyes of deep-sea fish that live in dim light conditions.
Mechanisms underlying gut microbiota–host interactions in insects
