Example sentencesExamples - Alternatively, they may be used to signal to predators, the classic example being aposematic coloration in species that have noxious defenses, such as skunks.
- Future research into the possible role of aposematic coloration in vascular plants could greatly expand our knowledge of plant/herbivore interactions.
- Many animals and insects that taste awful, sting or can otherwise turn a good day sour have adapted this warning-label strategy, known as aposematic coloration.
- Regression of the shell, development of aposematic colorations, and acquisition of toxic defenses are general evolutionary trends within the group.
- Arthropods smaller than 1 mm, ants, isopods, and arthropods with aposematic colorations were excluded from the counts because these are rarely consumed by insectivorous birds.
- 1.1 (of an animal) having aposematic coloration or markings.
Example sentencesExamples - Birds with prior experience of both prey types were allowed into an arena with both palatable prey and aposematic prey on backgrounds that either closely matched or contrasted with the coloration of the aposematic prey.
- To further investigate the effects of prey contrast on predator behavior, I conducted an experiment with young chicks (Gallus gallus domesticus) as predators on live aposematic and nonaposematic prey.
- Additionally, taxonomically troubling taxa such as Crataegus makes identification and quantification of aposematic species extremely difficult.
Derivatives noun Zoology The present study was originally carried out to compare the larval bioluminescence of L. noctiluca with the color of light-emitting diodes that were used to mimic larval glows in experiments on bioluminescent aposematism. Example sentencesExamples - The coupling of these attributes suggests that there is adaptive value to protection against predation by being less visually apparent, chemically defended, or for larger animals, by aposematism.
- Thus, although aposematism is common (96% of armed plants), it is not present in all physically armed plants even in closely related taxa (S. Lev-Yadun, pers. comm.).
- The field and herbarium study permitted us to document aposematism in the native and naturalized vascular flora of the region.
- Hypothesized forces selecting for coloration in sponges include aposematism (warning coloration), as has been shown in a variety of marine and terrestrial organisms, and photoprotection.
