This paper describes the results of a multivariate and univariate morphometric analysis of
three groups of Arctic charr Salvelinus alpinus from Loch Rannoch, Perthshire, Scotland …

Status of individual animals is often shown in pigmentation. For instance, stress
responsiveness is associated with melanin-based pigmentation in vertebrates in general …

The main aim of our experiments was to study the influence of colored light on juveniles of
Carassius carassius, Perccottus glenii and Poecilia reticulata. The species of fish used for …

Aquatic organisms are exposed to highly variable light environments, which can affect the
efficacy of colour patterns that are used for communication or camouflage. Specifically …

Intraspecific body colour variation is common in many animal species. Predation could be a
key selective agent giving rise to variation in body colour, and such variation could be due to …

Grouping behaviour is widespread across the animal kingdom, and is known to reduce an
individual's risk of predation, for example through predator confusion. Theory predicts that …

Physiological colour change was investigated in the blackspotted rockskipper
Entomacrodus striatus in Moorea, French Polynesia. Fish colour cycled with significant …

In aquatic environments, visual communication is expected in animals that inhabit clear,
shallow waters. Here, we investigate variation in the colorful traits of bluegills, Lepomis …

The ability of age‐0 year yellow perch Perca flavescans to detect prey using visual and
mechano‐sensory input was examined during laboratory feeding trials at varying light …

The development of photobehavioural responses in brook (Salvelinus fontinalis) and lake
(S. namaycush) charr was studied by monitoring the intrasubstrate movements and …
