Warning coloration in the Heteroptera bird predator behaviour, ecology, and phylogeny (IAA6141102)

-aposematic controls) and birds differing in their foraging strategies. Basic problems: 1) Are all the aposematic Heteroptera avoided by birds, or is the situation selective in the field. 2) Are mimetic complexes of aposematic

Factors responsible for variation in behaviour of predators towards aposematic prey (GAP505/11/1459)

Aposematic animals advertise their noxiousness to potential predators to discourage them from attack.However, different predators may behave differently towards in reactions of predators towards the aposematic prey. We shall use two...

Evolution of aposematic patterns in large Müllerian mimetic systems (GA18-14942S)

Multiple local patterns, intraspecific polymorphism and species with their own aposematic pattern should not persist in mutualistic Müllerian mimetic systems due phylogenies to study the evolution of aposematic patterns in a histori...

Recognition of predators and other dangerous organisms by terrestrial vertebrates (IAA601410803)

The ability to avoid dangerous organisms is very important preconditions for fitness in wild animals. Most often, animals are confronted by their predators and by an unpalatable or poisonous prey. The reliable recognition of a potential enemy has to ...

How ladybirds got their spots Genetics and ecology of colouration of Coccinellidae (GA20-10003S)

The identity of the gene that controls four main colour patterns of highly polymorphic ladybird Harmonia axyridis was recently discovered by two teams – Japanese and French. Because we possess a unique set of strains of rare natural colour morphs and...

Mimetic complexes and the evolution of inaccurate mimics (GA19-09323S)

Mimicry, a phenotypic resemblance among different species due to selection by predators, represents one of intriguing topics in evolutionary biology. Species that form mimetic complexes range from unpalatable to palatable (forming Batesian-Muellerian...
