The relationship between negative specific growth rate (SGR) during feed deprivation and positive SGR during re-feeding in a cohort of 2000 individual sea bass aged 0+ years. The fish were submitted to two sequential six-week cycles comprising three weeks feed deprivation and three weeks re-feeding. Each datapoint represents the mean SGR for an individual for the two periods of deprivation versus the two periods of re-feeding. Upper panel shows SGR data, lower panel shows SGR data corrected for initial body length (please see text for details). The coloured squares indicate the individuals that were subsequently studied for their physiology, yellow being ‘deprivation phenotypes’ and blue being ‘growth phenotypes’.

Mean (±s.e.m.) rates of oxygen uptake in two groups of sea bass over 45 h after either sham feeding (closed symbols) or force-feeding with a ration of fish fillet equivalent to 3% of their body mass (open symbols). The groups represent phenotypes from the opposing ends of the trade-off between tolerance of feed deprivation and compensatory growth rate carried in Fig. 1. (A) Deprivation phenotypes, (B) growth phenotypes. N=7 in all cases. Rates are corrected to a mean fish mass of 400 g. An asterisk indicates a significant difference between sham and fed at that time point, all values within the arrows are significant (P<0.05 by Holm–Sidak test post-hoc to two-way ANOVA for repeated measures, see text for further details).

Mean (±s.e.m.) rates of oxygen uptake due to specific dynamic action (normalised against standard metabolic rate) in two groups of sea bass for 45 h after force-feeding with a ration of fish fillet equivalent to 3% of their body mass. The groups represent phenotypes from the opposing ends of the trade-off between tolerance of feed deprivation and compensatory growth rate carried in Fig. 1. (A) Deprivation phenotypes, (B) growth phenotypes. N=7 in all cases. Rates are corrected to a mean fish mass of 400 g. An asterisk indicates a significant difference from zero (standard metabolic rate) at that time interval for that phenotype (all values within the arrows are significant), a dagger indicates a significant difference between phenotypes at that time interval (P<0.05 by Holm–Sidak test post-hoc to two-way ANOVA for repeated measures, see text for further details).

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.
