Interspecific social dominance mimicry in birds
Interspecific social dominance mimicry (ISDM) is a proposed form of social parasitism in which a subordinate species evolves to mimic and deceive a dominant ecological competitor in order to avoid attack by the dominant, model species. The evolutionary plausibility of ISDM has been established previously by the Hairy-Downy game (Prum & Samuelson). Psychophysical models of avian visual acuity su...
متن کاملPhylogenetic evidence for colour pattern convergence in toxic pitohuis: Müllerian mimicry in birds?
Bird species in the genus Pitohui are chemically defended by a potent neurotoxic alkaloid in their skin and feathers. The two most toxic pitohui species, the hooded pitohui (Pitohui dichrous) and the variable pitohui (Pitohui kirhocephalus), are sometimes strikingly patterned and, in certain portions of their geographical ranges, both species share a nearly identical colour pattern, whereas in ...
متن کاملColor mimicry of empty seeds influences the probability of predation by birds
Seeds are under strong pressure from seed predators. Therefore any physical seed trait increasing the chances of the seed’s survival should undergo positive selection. Seed color polymorphism, varying from pale to dark seeds, occurs in Scots pine (Pinus sylvestris), a keystone species of coniferous forests in Eurasia. This phenomenon can be explained by the production of large quantities of emp...
متن کاملMahnob Hmi Ibug Mimicry Database (mhi-mimicry)
The experiments from which this database contains the recordings, were conducted with the aim of the analysis of human interaction, in particular mimicry, and elaborate on the theoretical hypotheses of the relationship between the occurrence of mimicry and human affect. The recorded experiments are designed to explore this relationship. The corpus is recorded with 18 synchronised audio and vide...
متن کاملMimicry in Natural Language
This is not a paper about mime or vocal impersonation; this is a paper about metaphor. In particular, it is about the metaphors linguists use in talking about language. I will try to characterize some of the axioms which underlie the metaphor systems of much of modern linguistics, which I will call ‘Physical Metaphors’ for reasons which will become clear shortly, and will provide some different...
