Cover: A male hoverfly Eristalis tenax, showing enlarged facets of the fronto-dorsal eye. The diameter of facet lenses is larger here than elsewhere, leading to increased light capture and thus contrast sensitivity (facet diameter eyemap, below right). The region of greatest spatial acuity is closer to the visual equator (interommatidial angle eyemap, below left). Straw, Warrant and O'Carroll (pp. 4339−4354) show that motion-detecting neurons with receptive fields corresponding to this bright zone exhibit faster temporal tuning than similar neurons in females. This sexual dimorphism may be a male specialization for chasing and intercepting females while flying. f, frontal; d, dorsal; l, lateral. (Photo: Andrew Straw)

In the field with Robyn Hetem
Continuing our fieldwork series, Robyn Hetem reflects on working with species ranging from aardvark to zebra, and the impact COVID-19 has had on fieldwork.
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
In their Review, Konstantin Schmidt and Philipp Engel summarise recent findings about the mechanisms involved in gut colonisation and the provisioning of beneficial effects in gut microbiota–insect symbiosis.
