Physiological color change is important for background matching, thermoregulation as well
as signaling and is in vertebrates mediated by synchronous intracellular transport of …

Cichlid fishes constitute one of the most species-rich families of vertebrates. In addition to
complex social behaviour and morphological versatility, they are characterised by extensive …

Morphological skin colour change in fish is often referred to in the sole context of
background adaptation. It is becoming increasingly apparent that it is a broad phenomenon …

Fish social behavior can be affected by artificial environments, particularly by factors that act
upon species that show aggressive behavior to set social rank hierarchy. Although …

Effects of high stocking densities (HSDs) were evaluated for Nile tilapia fish (Oreochromis
niloticus) under culture to determine its influence on plasma cortisol and whole blood …

External eye appearance across primate species is diverse in shape and colouration, yet we
still lack an explanation for the drivers of such diversity. Here we quantify substantial …

Pigmentation is an important factor for the survival of organisms in different environments; in
fish, it plays a key role in social communication and shoal formation. Pigmentation mediates …

Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males,
Oreochromis niloticus (standard length, mean±SD, 14.38±1.31 cm), subjected to …

Nests are the key elements of the reproductive repertoire of several fish species.
Understanding the physiological aspects behind their nesting behaviour is imperative to …

Social behavior can influence physiological systems dramatically yet the sensory cues
responsible are not well understood. Behavior of male African cichlid fish, Astatotilapia …
