Crypsis through disruptive coloration in an isopod [PDF]

Proceedings of the Royal Society B: Biological Sciences, 1998
The white–spotted colour morph of the marine isopod Idotea baltica appears cryptic on the brown alga Fucus vesiculosus with its white–coloured epizoites Electra crustulenta and Balanus improvisus . This study shows that the crypsis of this coloration is achieved through disruptive coloration rather than through background matching.

An overview of the relationships between mimicry and crypsis

Biological Journal of the Linnean Society, 1981
There have been many different and conflicting definitions of mimicry. Some of the definitions of mimicry include crypsis and others do not. Each definition includes different groups of phenomena and uses different criteria to distinguish mimetic from non-mimetic phenomena.

Mimicry and crypsis - a behavioural approach to classification

Behavioural Processes, 1986
Mimetic strategies are characterized by interference in information processes, whereby certain signalreceivers are deceived by a mimic. The function of mimetic behaviour as well as of other behavioural patterns which have evolved is to satisfy the needs of the environment.

The interrelationship between crypsis and colour polymorphism

Ecology Letters, 2011
The mechanisms behind the evolution and maintenance of conspicuous visible polymorphisms comprising tens of morphs present a challenge to evolutionary theory. However, for cryptic forms Endler (Evol. Biol., 11, 1978, 319) conjectured that complex backgrounds facilitate polymorphism because in such habitats there are several ways to resemble the resting

Chemical crypsis in predatory ants

Experientia, 1979
The repellent responses of worker termites to ants are determined by the exocrine gland secretions of the latter. Specialized termite predators produce non-repellent aliphatic alcohols as the major components of their mandibular glands, whereas unspecialized con-generics usually produce repellent ketones and aldehydes.

Propaganda, Crypsis, and Slave-making

1995
In complex ecological communities, the ability to survive and reproduce is often tenuous at best. Many organisms do so by simply “bullying” their way through life, but for many others a more furtive approach is necessary. These latter animals resort to either blending into their environment, or to mimicking specific species-characteristic cues of other,

Soral Crypsis: Protective Mimicry of a Coccid on an Indian Fern

Journal of Integrative Plant Biology, 2008
Abstract Herbivory with crypsis is not well documented in ferns. The present record of cryptic coloration of coccid Saissetia filicum Boisduval (Homoptera: Coccidae) to the sori of a fern species Asplenium nidus L. (Aspleniaceae) is unique. Predatory beetles (Jauravia sp., Coleoptera: Coccinellidae) that feed on the coccids, are suggested to be ...

The Genus Crypsis (Gramineae) in the United States

Systematic Botany, 1979
The Old World grass genus, Crypsis, is represented in the United States by three naturalized taxa. Although these are usually treated as specifically distinct in America, European botanists consider two of them to be merely different growth forms of the same species. The few chromosome counts in the literature suggest x = 9 as the basic number.

Evolution of crypsis in feather lice

2012
Crypsis is the color resemblance of an animal to its background such that predators have difficulty in distinguishing it. Although a great deal is known about crypsis in free-ranging insects, crypsis in ectoparasites is still poorly understood. Among ectoparasites, feather lice provide a unique chance to test whether ectoparasites are cryptically ...

Frequency-dependent predation, crypsis and aposematic coloration

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1988
Abstract Frequency-dependent predation may maintain or prevent colour pattern polymorphisms in prey, and can be caused by a variety of biological phenomena, including perceptual processes (search images), optimal foraging and learning.
