Ontogenetic colour change of a sexual ornament in males of a damselfly: female mimicry, crypsis or both?
Female mimicry by males is a widespread phenomenon in several taxa and may be involved in aggression avoidance or facilitated access to resources. In...

Female preference for super-sized male ornaments and its implications for the evolution of ornament allometry
It has been argued that disproportionately larger ornaments in bigger males—positive allometry—is the outcome of sexual selection operating on the...

An unexpected age-related pattern in feather growth contributes to age-dependent ornament expression in a passerine bird
The length of the ornamental tail rectrices has been shown to be an important condition-dependent sexually selected trait in various bird species....

Sex-specific signalling of individual personality by a mutual plumage ornament in a passerine
AbstractThe significance of colour signals in species with strong sexual dimorphism and/or elaborated visual ornaments is rather well-understood....

Evidence from personal ornaments suggest nine distinct cultural groups between 34,000 and 24,000 years ago in Europe
Mechanisms governing the relationship between genetic and cultural evolution are the subject of debate, data analysis and modelling efforts. Here we...

Carotenoid skin ornaments as flexible indicators of male foraging behavior in a marine predator: Variation among Mexican colonies of brown booby (Sula leucogaster)
Carotenoid-dependent ornaments can reflect animals’ diet and foraging behaviors. However, this association should be spatially flexible and variable...

Reduced ornamentation became elaborated in benign environments in Pacific Swallows
Many empirical studies have focused on highly ornamented species to identify ecological factors that maintain the ornamentation or favour its...

Diet color affects female preference for mate color in the guppy Poecilia reticulata
It has been argued that a preexisting sensory bias for food color influences female mate preference for male ornament color. However, the effect of...

Structure of the Hair of the Don Hare Lepus tanaiticus (Leporidae, Lagomorpha) First Found in Pleistocene Deposits in Yakutia, Russia
AbstractUsing scanning electron microscopy (SEM), the external and internal structure of the hairs of an adult Pleistocene Don hare Lepus tanaiticus ...

Multiple traits predict reproductive success and assortative mating in mutually ornamented Campo flickers (Colaptes campestris campestris)
AbstractCooperative species have provided extensive evidence on the evolution of cooperation and kin selection mechanisms, but they have been poorly...

Leg coloration is associated with habitat type and social environment in swallows and martins
Plumage ornaments, such as colourful feathers and deeply forked tails, are classic examples of sexually selected ornaments, and are shown to be...

Swallows nesting on buildings showed positive population trends except when having deeply forked tails
In our rapidly urbanizing world, species utilizing anthropogenic resources would have positive population trends more than others, although its...

Role of Bioinformatics in Non-coding RNA Analysis
The transcriptome, comprising RNA molecules expressed in cells or tissues, is predominantly composed of non-coding RNAs (ncRNAs), which has most of...

Wild common crossbills produce redder body feathers when their wings are clipped
BackgroundThe animal signaling theory posits that conspicuous colorations exhibited by many animals have evolved as reliable signals of individual...

Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
The process of speciation generates biodiversity. According to the null model of speciation, barriers between populations arise in allopatry, where,...

Brighter is better: bill fluorescence increases social attraction in a colonial seabird and reveals a potential link with foraging
AbstractCrested auklets ( Aethia cristatella ) are colonial seabirds with brilliant orange bills during the breeding season. We characterized the bill...

Nest ornaments and feather composition form an extended phenotype syndrome in a wild bird
AbstractMany species throughout the animal kingdom construct nests for reproduction. A nest is an extended phenotype—a non-bodily attribute—of the...

Interrelationship Between Fractal Ornament and Multilevel Selection Theory
Interdisciplinarity is one of the features of modern science, defined as blurring the boundaries of disciplines and overcoming their limitations or...

Trade-offs between larval survival and adult ornament development depend on predator regime in a territorial dragonfly
Trade-offs between juvenile survival and the development of sexually selected traits can cause ontogenetic conflict between life stages that...
