Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Epistasis

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Complementation Tests

Complementation Tests

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.Although predation is commonly associated with carnivory, for...

Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...

Summary

This summary is machine-generated.

Coincident disruptive coloration, where patterns align across body parts, effectively conceals animal shapes. This camouflage strategy prevents predators and observers from recognizing the overall form, even with perfect background matching.

Area of Science:

Ecology
Evolutionary Biology
Animal Behavior

Background:

Camouflage relies on matching surroundings in color and texture.
Mismatches in pattern phase or shadow can reveal an animal's form.
Disruptive coloration breaks object recognition by disrupting shape and form.

Purpose of the Study:

To investigate the effectiveness of coincident disruptive coloration in camouflage.
To determine if aligned patterns across body parts enhance concealment.
To test the role of pattern phase in predator-prey interactions.

Main Methods:

Field experiments using artificial moth-like targets with varying color patterns and predation by wild birds.
Computer-based experiments with human observers searching for similar targets.
Manipulation of pattern coincidence across wings and body sections of targets.

Main Results:

Coincident disruptive coloration significantly improved camouflage effectiveness.
Both avian predators and human observers had reduced ability to detect targets with aligned patterns.
Absence of phase disjunction across body parts was crucial for concealment.

Conclusions:

Coincident disruptive coloration is a highly effective camouflage mechanism.
This strategy aids in concealing an animal's body form by disrupting shape recognition.
Pattern alignment across different body sections is key to successful disruptive camouflage.
