Larvae of Aedes campestris ingest and absorb into their haemolymph large quantities of the sulphate-rich water in which they live, yet they are able to maintain the sulphate content of the haemolymph well below that of the environment.
- 2.
Tracer experiments showed that sulphate regulation was not achieved by deposition of precipitates in the tissues.

In vitro preparations of Malpighian tubules secrete sulphate ions actively against both a three times concentration gradient and an electrical potential difference of 20 mV. This transport is half saturated at about 10 mM.
- 4.
The rate of sulphate secretion by the Malpighian tubules is sufficient to remove all of the sulphate ingested by larvae living in waters which contain less than 100 mM of this anion. At higher concentrations, sulphate ions are probably also excreted elsewhere, perhaps by the rectum or anal papillae.
New funding schemes for junior faculty staff
In celebration of our 100th anniversary, JEB has launched two new grants to support junior faculty staff working in animal comparative physiology and biomechanics who are within five years of setting up their first lab/research group. Check out our ECR Visiting Fellowships and Research Partnership Kickstart Travel Grants. First deadline for applications is 15 July 2023.
JEB@100: an interview with Monitoring Editor Sanjay Sane
Sanjay Sane tells us about his first experience of publishing with the journal and why he thinks JEB is going to play a key role in our understanding of the current climate crisis and its implications for biodiversity.
The Forest of Biologists
The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Journal of Experimental Biology a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
Celebrating 100 years of discovery
This Special Issue focuses on broad biological questions addressed through the lens of comparative biomechanics. Crosscutting through time, this series of Reviews, Commentaries and Research Articles addresses questions from the vantage points of the history of the field, today’s research, and the future of comparative biomechanics. Read the Editorial by Sheila Patek, Monica Daley and Sanjay Sane.
Centenary Review - Adaptive echolocation behavior
Cynthia F. Moss and colleagues Review the behaviours used by echolocating mammals to track and intercept moving prey, interrogate dynamic sonar scenes, and exploit visual and passive acoustic stimuli.
Lack of oxygen curtails vision in red-eared sliders
When red-eared sliders sink to the bottom of a frozen pond for winter they reduce many biological systems to minimum life support, but now Michael Ariel and colleagues show that the reptiles temporarily lose their sight due to lack of oxygen but retain hearing.
