A histological analysis of coloration in the Peruvian mimic poison frog (Ranitomeya imitator) [PDF]
PeerJ, 2023 Aposematism continues to be a phenomenon of central interest in evolutionary biology. The life history of the mimic poison frog, Ranitomeya imitator, relies heavily on aposematism.

Hidden colour signals as key drivers in the evolution of anti-predator coloration and defensive behaviours in snakes [PDF]
Nature CommunicationsThe initial evolution of warning coloration (“aposematism”) within a cryptic population of defended prey presents an evolutionary paradox. A recent phylogenetic analysis of amphibia suggests a new solution: prey that combine cryptic colours with ...

Conspicuous stripes on prey capture attention and reduce attacks by foraging jumping spiders [PDF]
Royal Society Open Science, 2023 Many animals avoid predation using aposematic displays that pair toxic/dangerous defences with conspicuous achromatic warning patterns, such as high-contrast stripes.

Visual-, Olfactory-, and Nectar-Taste-Based Flower Aposematism [PDF]
PlantsFlorivory, i.e., flower herbivory, of various types is common and can strongly reduce plant fitness. Flowers suffer two very different types of herbivory: (1) the classic herbivory of consuming tissues and (2) nectar theft.

Coevolutionary patterns between coloration and diel activity in moths [PDF]
Royal Society Open ScienceAnti-predator coloration is part of a key survival strategy in animals, often coevolving with behavioural traits such as diel activity. While previous studies have explored the link between conspicuous sexual signals and diurnality, the association ...

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal [PDF]
Ecology and EvolutionMany prey species defend themselves against predators by sequestering toxins, which they advertise using conspicuous warning signals—a survival strategy termed ‘aposematism’.

Unveiling the Defenses: A Current and Comprehensive Review of Coleoptera Carabidae Strategies [PDF]
BiologyThe Carabidae family, or ground beetles, is a wide and ecologically significant group within the Coleoptera order, known for its role as natural predators of agricultural pests and as bioindicators of ecosystem health.

Imperfections in transparency and mimicry do not increase predation risk for clearwing butterflies with educated predators [PDF]
Ecology and EvolutionTransparency is an intuitive form of concealment and, in certain butterflies, transparent patches on the wings can contribute to several distinct forms of camouflage.

Context-Dependent Anti-Predator Behavior in Nymphs of the Invasive Spotted Lanternfly (Lycorma delicatula): Effects of Development, Microhabitat, and Social Environment [PDF]
InsectsAntipredator behaviors in animals often vary with developmental stage, microhabitat, and social context, yet few studies examine how these factors interact in species that undergo ontogenetic shifts in chemical defense.

Function of Vivid Coloration of Terrestrial Isopods from the Point of View of an Avian Predator [PDF]
InsectsThe ability of terrestrial isopods (Crustacea: Isopoda: Oniscidea) to protect themselves effectively from predation by birds has never been tested. They are equipped with glands producing chemical substances; moreover, some species show conspicuous ...
