Carotenoids are among the most prevalent pigments used in animal signals and are also
important for a range of physiological functions. These concomitant roles have made …

We explore the relevance of honest signalling theory to the evolution of aposematism. We
begin with a general consideration of models of signal stability, with a focus on the Zahavian …

Many prey species use colourful 'aposematic'signalling to advertise the fact that they are
toxic. Some recent studies have shown that the brightness of aposematic displays correlates …

Carotenoids are long conjugated isoprenoid molecules derived mainly from plants and
microbial organisms. They are highly diverse, with over 700 identified structures, and are …

Evolution of conspicuous signals may be constrained if animal coloration has nonsignaling
as well as signaling functions. In aposematic wood tiger moth (Parasemia plantaginis) …

Many chemically-defended/aposematic species rely on diet for sequestering the toxins with
which they defend themselves. This dietary acquisition can lead to variable chemical …

Prey species often possess defences (eg toxins) coupled with warning signals (ie
aposematism). There is growing evidence that the expression of aposematic signals often …

The colours of insects function in intraspecific communication such as sexual signalling,
interspecific communication such as protection from predators, and in physiological …

Aposematic herbivores are under selection pressure from their host plants and predators.
Although many aposematic herbivores exploit plant toxins in their own secondary defense …

This study investigates complex effects of parasitoid infection on herbivore diet choice.
Specifically, we examine how immunological resistance, parasitoid infection stage, and …
