Origin and Biogeography of the Colourful Sap‐Sucking Sea Slugs Genus Thuridilla Bergh, 1872 (Mollusca, Gastropoda, Heterobranchia)

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Thuridilla Bergh, 1872, is a lineage of herbivorous sea slugs externally distinguished by bright colours and distinctive patterns of lines and spots. Recent work revealed an exceptionally rapid, cryptic radiation of 13 species in the Indo‐Pacific, raising questions about mechanisms of speciation in this group.

Not all social coral reef fishes form strict size‐based dominance hierarchies: An investigation of intraspecific size ratios in Dascyllus aruanus

open access: yesJournal of Fish Biology, EarlyView.
Abstract We present a random pattern of body size ratios between adjacent ranked group members in the humbug damselfish Dascyllus aruanus. This random distribution of size ratios differs from the other well‐known group‐living coral reef fishes which exhibit non‐random, well‐defined and closely regulated size differences between ranks.

The effect of early life thermal environment on morphology and growth of yellow perch (Perca flavescens)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Early life development in fishes is a period of high phenotypic plasticity. Water temperatures during embryogenesis can lead to alterations in growth and metabolic and morphological phenotypic variations. This study aimed to characterize the effects of temperature on the growth and morphology of yellow perch throughout early development, a ...
