Maintenance of a fruit colour polymorphism along an elevational gradient in the Southern Alps of New Zealand
Many plants produce colour-polymorphic fruits. However, the processes responsible for the evolution and maintenance of fruit colour polymorphisms are...

A masculinizing supergene underlies an exaggerated male reproductive morph in a spider
In many species, individuals can develop into strikingly different morphs, which are determined by a simple Mendelian locus. How selection shapes...

Which side are you on? Spider web positioning affects prey capture more than body colour
Colour has been hypothesized to play a crucial role in prey capture for sit-and-wait predators that rely on visual cues to deceive their prey. Prey...

Increased solar radiation and soil moisture determine flower colour frequency in a mountain endemic plant population
Flower colour is a fascinating trait that has been of interest to biologists for its utility in understanding variation in natural populations and...
-
Colour-specific diet specialization is associated with differences in owlet weight in a polymorphic owl: influence of the trophic quality variation
The niche divergence hypothesis proposes that the evolution and maintenance of colour polymorphism is based on a mechanism of disruptive selection....

Factors determining variation in colour morph frequencies in invasive Harmonia axyridis populations
The Harlequin ladybird Harmonia axyridis Pallas, native to eastern Asia, is an invasive, non-native species that has recently achieved an almost...

Specialist predation covaries with colour polymorphism in tawny owls
AbstractUnderstanding intraspecific phenotypic variation in prey specialisation can help to predict how long-term changes in prey availability affect...

Sexual selection on population-level mating opportunities drives morph ratios in a fig wasp with extreme male dimorphism
BackgroundAlternative mating tactics are widespread in animals and associated with extreme morphological polymorphism in some insects. Some fig wasps...

Functional interactions between coat structure and colour in the determination of solar heat load on arid living kangaroos in summer: balancing crypsis and thermoregulation
Interactions of solar radiation with mammal fur are complex. Reflection of radiation in the visible spectrum provides colour that has various roles,...

A new morph of Telmatochromis temporalis (Cichlidae; Cichliformes) from Lake Tanganyika
Telmatochromis temporalis is a cichlid fish endemic to Lake Tanganyika. Two morphs of this species, normal and dwarf, form a good model for the study...

The orchid mantis exhibits high ontogenetic colouration variety and intersexual life history differences
Masquerade, the resemblance of animals to inedible or inanimate objects, exists universally throughout the animal kingdom, especially in arthropods....

Ontogenetic colour change and distributional aspects of Lepidion guentheri (Giglioli 1880) (Gadiformes, Moridae)
The occurrence of a small specimen of Lepidion guentheri (Giglioli, 1880) (Gadiformes: Moridae) with an unusual dark colouration in the Porcupine...

Female-female aggression and male responses to the two colour morphs of female common cuckoos
Female-only colour polymorphism is rare in birds, but occurs in brood parasitic cuckoos (Cuculidae). Obligate brood parasites leave incubation and...

The genomics and evolution of inter-sexual mimicry and female-limited polymorphisms in damselflies
Sex-limited morphs can provide profound insights into the evolution and genomic architecture of complex phenotypes. Inter-sexual mimicry is one...

Information content of ultraviolet-reflecting colour patches and visual perception of body coloration in the Tyrrhenian wall lizard Podarcis tiliguerta
AbstractColour signals are ubiquitous in nature but only recently have researchers recognised the potential of ultraviolet (UV)-reflecting colour...

Evidence of non-random mating in a colour polymorphic raptor, the Booted Eagle
Sexual selection and non-random mating are considered, among others, determinant mechanisms for the maintenance of genetic colour polymorphism in...
-
Partially coupled reaction norms of pupal colour and spot size in a butterfly
Many species cope with heterogeneous environments through adaptive phenotypic plasticity, and plasticity of body colour is a widely used means of...

Diversity in flower morphology of the single-type tuberose (Agave amica (Medik.) Thiede & Govaerts)
Tuberose [ Agave amica (Medik.) Thiede & Govaerts] is a tropical bulb grown commercially for its sweet-scented flowers and highly valued essential...

Ancillary polymorphic floral traits between two morphs adaptive to hawkmoth pollination in distylous plant Tirpitzia sinensis (Linaceae)
BackgroundFloral morphs are characterized differentiations in reciprocal positions of sexual organs and ancillary floral traits in heterostylous...

Extreme Y chromosome polymorphism corresponds to five male reproductive morphs of a freshwater fish
Loss of recombination between sex chromosomes often depletes Y chromosomes of functional content and genetic variation, which might limit their...
