Aposematism: balancing salience and camouflage.
Aposematic signals are often characterized by high conspicuousness. Larger and brighter signals reinforce avoidance learning, distinguish defended from palatable prey and are more easily memorized by predators. Conspicuous signalling, however, has costs: encounter rates with naive, specialized or nutritionally stressed predators are likely to increase. It has been suggested that intermediate le...
متن کاملDistance-dependent aposematism and camouflage in the cinnabar moth caterpillar (Tyria jacobaeae, Erebidae)
Defended prey often use distinctive, conspicuous, colours to advertise their unprofitability to potential predators (aposematism). These warning signals are frequently made up of salient, high contrast, stripes which have been hypothesized to increase the speed and accuracy of predator avoidance learning. Limitations in predator visual acuity, however, mean that these patterns cannot be resolve...
متن کاملAposematism
What is aposematism? The word comes from the Greek apo (away) and sema (sign) and describes a strategy whereby animals warn predators about their unprofitability. It consists of two elements: a primary defence, such as distinctive colours, odours or sounds, that operates before the predator attacks; and a secondary defence, be it chemical, morphological or behavioural that make prey unprofitabl...
متن کاملTowards Balancing Conciseness, Readability and Salience: an Integrated Architecture
In this paper we present an architecture for generating texts that vary in the emphasis put on conciseness, readability and the marking of particularly salient items. We abandon the traditional pipeline architecture, and use an integrated approach which makes the search for an optimum text explicit, taking into account both inter-sentential and intra-sentential features. We describe a context s...
متن کاملChemical aposematism Paul
Discussions of aposematism traditionally have focused on the visual displays of prey that denote unpalatability or toxicity to predators. However, the construct of aposematism accommodates a spectrum of unprofitable traits signaled through various sensory modalities, including contact and distance chemoreception. Aposematism, involving learned aversions by signal receivers or selection for thei...
