Impacts And Implications Of Polytypism On The Evolution Of Aposematic Coloration
Aposematic signaling is a comdefensive strategy whereby prey species use conspicuous signals (i.e., bright coloration) to warn predators of the risks of predation due to a secondary defense. Theoretical, lab, and field experiments have demonstrated that individuals who project novel conspicuous …

The Effect of Aposematic Coloration on the Food Preference of Aphelocoma coerulescens, the Florida Scrub Jay
<p>Aposematic coloration, commonly observed in noxious organisms, serves as a warning to predators to avoid attacking specific prey. This coloration is conspicuous in nature, with one of the most common examples being a red and black pattern. The plant Abrus precatorius exhibits this warning signal …

HIDE AND SEEK: AN EXPLORATION OF ANTIPREDATOR AND PREDATOR AVOIDANCE MECHANISMS IN ORTHOPODOMYIA SIGNIFERA IN RESPONSE TO PREDATION FROM TOXORHYNCHITES RUTILUS
… </em>possess a chemical defense indicated by aposematic coloration. To test the first hypothesis larval <em>Or. signifera</em> were exposed to conspecific and heterospecific predation cues and their behavior was observed. Both cues caused <em>Or. signifera</em> to change their behavior, with …

Behavioural and ecological interactions between Heliconius butterflies, their predators and host plants
… and defending against visual predators through aposematic coloration. As both selection pressures are likely to be strong, different elements of the signal might be adapted for different receivers. Here, I combine sensory ecology with behavioural ecology to explain Heliconius colours signals of …

Developmental timing of pupation and analysis of color pattern response to thermal stress in Bombus impatiens (Hymenoptera: Apidae)
… geographic range sometimes converge on similar aposematic coloration to presumably increase the efficacy of learned predator avoidance. However, the extent to which other selective pressures affect color pattern evolution remains largely untested. Temperature is an important environmental …

Hiding in plain sight: unveiling cryptic diversity and patterns in bumble bees
… bees have long served as classic examples of aposematic coloration and their convergence upon common patterns across their extensive distribution has served as a classic example of Müllerian mimicry. Yet nothing is known about the developmental regulation of these color patterns. As a first …
