Conspicuousness and toxicity of Coccinellidae: An aposematic review [PDF]

Arthropods, 2020
Coccinellids (commonly known as ladybirds) mostly exhibit bright clouration and play a vital role in biological control of pests of important crops such as aphids and scale insects.

Multimodal Aposematic Defenses Through the Predation Sequence

Frontiers in Ecology and Evolution, 2021
Aposematic organisms warn predators of their unprofitability using a combination of defenses, including visual warning signals, startling sounds, noxious odors, or aversive tastes.

Ultraviolet components offer minimal contrast enhancement to an aposematic signal

Ecology and Evolution, 2020
Aposematic and sexual signals are often characterized by bright, highly contrasting colors. Many species can see colors beyond the human visible spectrum, and ultraviolet (UV) reflection has been found to play an important role in communication and ...

Red coloration and the evolution of aposematism in arboreal sciurids

, 2022
An animal's coloration is associated with a variety of processes and is therefore subjected to multiple selective pressures. Mammals, especially, are typically inconspicuously colored, or cryptic, to avoid detection by predators. Alternatively, an animal

Numbers, neighbors, and hungry predators: What makes chemically defended aposematic prey susceptible to predation?

Ecology and Evolution, 2020
Many chemically defended aposematic species are characterized by relatively low toxin levels, which enables predators to include them in their diets under certain circumstances.

The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis [PDF]

Ecol Evol
This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Aposematism: An Alternative Hypothesis on How We Discover Medicinal Organisms [PDF]

, 2017
The most widely accepted theories as to how primates select medicinal organisms are based on smelling-tasting bitter, and most of the times toxic, plants (Etkin & Ross, 1982; Johns, 1990).

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.
