Capture tolerance: A neglected third component of aposematism?
Aposematism (considered here as an association between conspicuous colour patterns and the presence of a harmful secondary defence) has long been...
-
Coevolution of group-living and aposematism in caterpillars: warning colouration may facilitate the evolution from group-living to solitary habits
BackgroundAnimals use diverse antipredator mechanisms, including visual signalling of aversive chemical defence (aposematism). However, the initial...

The molecular basis and evolution of toxin resistance in poison frogs
Many animals bear conspicuous warning signals that advertise toxin-mediated unpalatability to predators; this is known as aposematism. Frogs in...

Testing of two of the visual anti-herbivory strategies of red young leaves: aposematic versus undermining herbivorous insect’s camouflage
A recent important paper (Ide, Arthropod-Plant Interact 16:567–581, 2022) reported the experimental testing of two (out of several) of the visual red...

In paired preference tests, domestic chicks innately choose the colour green over red, and the shape of a frog over a sphere when both stimuli are green
Many animals express unlearned colour preferences that depend on the context in which signals are encountered. These colour biases may have evolved...
-
Experimental evidence in a poison frog model suggests that tadpole transport on the dorsum may affects warning signal effectiveness in poison frogs
Aposematism is an anti-predator strategy where predators learn to associate the warning signal on prey with an unpleasant experience, and...

Colours as aggregation signals in Lepidoptera: Are Heliconius Müllerian mimics?
Butterflies are frequently conspicuous. The function of this conspicuousness is understudied and may vary between species or family. Aposematism has...

Which side are you on? Spider web positioning affects prey capture more than body colour
Colour has been hypothesized to play a crucial role in prey capture for sit-and-wait predators that rely on visual cues to deceive their prey. Prey...

How to move and when to escape: quantifying intraspecific exploratory and anti-predator behavior in an aposematic poison frog
Aposematic animals are chemically defended and tend to have bright and conspicuous color patterns that warn predators of the costs of attack. Most...

Fear of the dark: substrate preference in Amazonian tadpoles
Due to the importance of camouflage to avoid detection by predators, predation pressure can cause coupled evolution of skin colour and preference for...

Chemical defense and tonic immobility in early life stages of the Harlequin cabbage bug, Murgantia histrionica (Heteroptera: Pentatomidae)
Antipredation strategies contribute to the lifetime reproductive success of organisms, particularly in more vulnerable life stages that look to...

The debris-cloaking larva of Catapotia laevissima and the origin of defensive strategies in Anamorphidae and other Coccinelloidea (Coleoptera)
Debris-cloaking, a method of concealment with material collected from the environment, has evolved repeatedly with the purpose of avoiding detection...
-
Conspicuous and cryptic poison frogs are picky and prefer different meals in syntopy
The poison frog family (Anura: Dendrobatidae) consists of species with conspicuous (e.g., warning coloration and toxicity or low palatability) and...

Investigating the Effects of Male Size and Pronotal Glowspots on Female Courtship Behaviour of the Glowspot Cockroach (Lucihormetica verrucosa)
Lucihormetica verrucosa (Blattodea, Blaberidae) are highly sexually dimorphic cockroaches, with the males having two symmetrically organised...

Linking Predator Responses to Alkaloid Variability in Poison Frogs
Many chemically-defended/aposematic species rely on diet for sequestering the toxins with which they defend themselves. This dietary acquisition can...

Ecological role of bioluminescence of Black sea ctenophores
Bioluminescence, which is a manifestation of the vital activity of an organism in the form of electromagnetic radiation in the visible area of the...

The evolution of prey-attraction strategies in spiders: the interplay between foraging and predator avoidance
Lures and other adaptations for prey attraction are particularly interesting from an evolutionary viewpoint because they are characterized by...
-
Acoustic Defence Strategies in Caterpillars
Caterpillars are attacked by a wide range of predators and parasitoids. Consequently they have evolved a plethora of defences to avoid, repel, or...

Integrating ecological niche modeling and rates of evolution to model geographic regions of mimetic color pattern selection
Geographic variation in natural selection derived from biotic sources is an important driver of trait evolution. The evolution of Müllerian mimicry...
