Sex-limited morphs can provide profound insights into the evolution and genomic architecture of complex phenotypes.

ABSTRACT Trait polymorphisms are a perennially popular topic of study in ecology and evolutionary biology. Plumage occur broadly birds, with particularly high rate among the raptors. The regularity this heritable, melanin-based trait raptors has prompted research into its potential connections to aspects life history such as immune response, foraging ecology, mating systems. Because non-monophyletic grouping multiple orders, they can further be leveraged explore eco-evolutionary drivers recurrent plumage polymorphism phenotypes. Here we characterize throughout review existing literature on factors involved development maintenance. We identify patterns trends past body discuss opportunity strengthen our understanding through holistic approach. Specifically, detail likely benefits applying genomic tools while encouraging both focus unstudied polymorphic species interactions hypotheses that might promote polymorphism.

Female-limited polymorphisms, where females have multiple forms but males only one, been described in a variety of animals, yet are difficult to explain because selection typically is expected decrease rather than maintain diversity. In the white-necked jacobin (Florisuga mellivora), all and approximately 20% express an ornamented plumage type (androchromic), while other non-ornamented (heterochromic). Androchrome benefit from reduced social harassment, it remains unclear why both morphs persist. Female may represent balanced alternative behavioural strategies, hypothesis that androchrome mimicking males. Here, we test critical prediction these hypotheses by measuring morphological, physiological traits relate resource-holding potential (RHP), or competitive ability. traits, find little difference between female types, higher RHP These results, together with previous findings this species, indicate increase access food resources through mimicry more aggressive Importantly, provides clear theoretical pathway for polymorphism maintenance frequency-dependent selection. Social dominance mimicry, long suspected operate can therefore also within leading perhaps similarities sexes generally.

In her influential book "Developmental Plasticity and Evolution," Mary Jane West-Eberhard introduced the concept of cross-sexual transfer, where traits expressed in one sex an ancestral species become other sex. Despite its potential ubiquity, we find that transfer has been under-studied under-cited literature, with only a few experimental papers have invoked concept. Here, aim to reintroduce as powerful framework for explaining variation highlight relevance current studies on evolution sexual heteromorphism (different means or modes trait values between sexes). We discuss several exemplary published past two decades, further building West-Eberhard's extensive review. emphasize scenarios avenues study, within-sex polymorphic sex-role reversed species, evolutionary adaptive implications. Lastly, propose future questions expand our understanding from nonhormonal mechanisms identification broad taxonomic patterns. As biologists increasingly recognize nonbinary often continuous nature heteromorphism, important utility generating novel insights perspectives phenotypes across diverse taxa.

Traits that exhibit differences between the sexes have been of special interest in study phenotypic evolution. Classic hypotheses explain sexually dimorphic traits via intra-sexual competition and mate selection, yet natural selection may also act differentially on to produce dimorphism. Natural can either through physiological ecological constraints one sexes, or by modulating strength sexual/social selection. This predicts an association degree dimorphism variation environments. Here, we characterize hummingbird across gradients using rich databases morphology, colouration song. We show morphological decreases with elevation understorey increases mixed habitats, dichromatism at high altitudes open song is less complex habitats. Our results are consistent flight constraints, lower predation pressure elevations habitat effects transmission. complexity positively associated, while tail negatively associated. suggest key factors shape traits, different communication modalities do not always evolve tandem.
