31.06 – Behind the cover

Our latest issue out now, with a cover  from Sonia Bejarano et al’s paper The shape of success in a turbulent world: wave exposure filtering of coral reef herbivory. Coral reef fishes (herbivorous fishes in particular) play a crucial role in maintaining productive and healthy coral-dominated systems. Some species are considered slow swimmers (based on the shape of their fins), so tend to be excluded from turbulent habitats. The way herbivorous fishes and their feeding rates are affected by wave exposure, based on their overall swimming performance, is poorly understood. The authors assessed the swimming performance of 37 fish species using ten morphological traits related to swimming mode, speed, and manoeuvrability and recorded their feeding frequency using video cameras on 12 sites distributed across sheltered, moderate, and turbulent coral reefs.

Also in this issue, our latest commentary from Halsey gives a note of caution about energy expenditure‐proxy correlations, Vanbergen et al look at how network size, structure and mutualism dependence affect the propensity for plant–pollinator extinction cascades and Grutters et al explore how plant traits and plant biogeography control the biotic resistance provided by generalist herbivores.
