Environmental modulation of metabolic allometry in ornate rainbowfish Rhadinocentrus ornatus

Environmental modulation of metabolic allometry in ornate rainbowfish Rhadinocentrus ornatus.

The nature of the relationship between the metabolic rate (MR) and body mass (M) of animals has been the source of controversy for over seven decades, with much of the focus on the value of the scaling exponent b, where MR is proportional to M(b). While it is well known that MR does not generally scale isometrically (i.e. b is seldom equal to 1), the value of b remains the subject of heated deb...

Evening up the score: sexual selection favours both alternatives in the colour-polymorphic ornate rainbowfish

Pathogenicity and infection cycle of Vibrio owensii in larviculture of the ornate spiny lobster (Panulirus ornatus).

The type strain of Vibrio owensii (DY05) was isolated during an epizootic of aquaculture-reared larvae (phyllosomas) of the ornate spiny lobster (Panulirus ornatus). V. owensii DY05 was formally demonstrated to be the etiological agent of a disease causing rapid and reproducible larval mortality with pathologies similar to those seen during disease epizootics. Vectored challenge via the aquacul...

Complete Genome Sequence of a Bohle iridovirus Isolate from Ornate Burrowing Frogs (Limnodynastes ornatus) in Australia

Bohle iridovirus (BIV) is a species within the genus Ranavirus, family Iridoviridae, first isolated from the ornate burrowing frog Limnodynastes ornatus in Australia. The BIV genome confirms it is closely related to isolates from boreal toad Anaxyrus boreas and leaf-tailed gecko Uroplatus fimbriatus within the United States and Germany, respectively.

Visual habitat geometry predicts relative morph abundance in the colour-polymorphic ornate rainbowfish.

During colour signalling in aquatic environments, the colour of the ambient light, the background against which signals are viewed and signal transmission through the environment can all have profound impacts on the efficacy of a given signal. In colour-polymorphic species, where alternative morphs persist owing to a balance in the natural and sexual selection for each, changes to the visual co...
