Ecological and geographical overlap drive plumage evolution and mimicry in woodpeckers

Nature Communications, Journal Year: 2019, Volume and Issue: 10(1)

Published: April 8, 2019

Abstract Organismal appearances are shaped by selection from both biotic and abiotic drivers. For example, Gloger’s rule describes the pervasive pattern that more pigmented populations found in humid areas. However, species may also converge on nearly identical colours patterns sympatry, often to avoid predation mimicking noxious species. Here we leverage a massive global citizen-science database determine how factors act concert shape plumage world’s 230 of woodpeckers. We find habitat climate profoundly influence woodpecker plumage, recover support for generality rule. many exhibit remarkable convergence explained neither these nor shared ancestry. Instead, this is associated with geographic overlap between species, suggesting occasional strong interspecific mimicry.

Feather function and the evolution of birds

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2022, Volume and Issue: 98(2), P. 540 - 566

ABSTRACT The ability of feathers to perform many functions either simultaneously or at different times throughout the year life a bird is integral evolutionary history birds. Many studies focus on single feathers, but any given feather performs over its lifetime. These necessarily interact with each other evolution and development birds, so our knowledge avian incomplete without understanding multifunctionality how may act synergistically antagonistically during natural selection. Here, we review evolution, recent technological discovery‐based advances. By synthesising research into hierarchical scales (pattern, arrangement, macrostructure, microstructure, nanostructure, molecules), aim provide broad context for adaptability have allowed birds diversify an astounding array environments life‐history strategies. We suggest that future involving function should consider multiple aspects feather, including functions, seasonal wear renewal, ecological mechanical interactions. With this more holistic view, processes such as coloration flight can be understood in broader nuanced context.

Amazonian birds in more dynamic habitats have less population genetic structure and higher gene flow

Molecular Ecology, Journal Year: 2023, Volume and Issue: 32(9), P. 2186 - 2205

Understanding the factors that govern variation in genetic structure across species is key to study of speciation and population genetics.

Evolution of communication signals and information during species radiation

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Oct. 2, 2020

Abstract Communicating species identity is a key component of many animal signals. However, whether selection for recognition systematically increases signal diversity during clade radiation remains debated. Here we show that in woodpecker drumming, rhythmic used mating and territorial defense, the amount information encoded remained stable woodpeckers’ radiation. Acoustic analyses evolutionary reconstructions interchange among six main drumming types despite strong phylogenetic contingencies, suggesting tinkering structure within constrained acoustic space. Playback experiments quantification discriminability demonstrate sufficient differentiation to support local communities. Finally, only find character displacement rare cases where sympatric are also closely related. Overall, our results illustrate how historical contingencies ecological interactions can promote conservatism signals without impairing effectiveness transfer relevant inter-specific discrimination.

Multiple and Independent Phases of Transposable Element Amplification in the Genomes of Piciformes (Woodpeckers and Allies)

Genome Biology and Evolution, Journal Year: 2018, Volume and Issue: 10(6), P. 1445 - 1456

Published: May 22, 2018

The small and conserved genomes of birds are likely a result flight-related metabolic constraints. Recombination-driven deletions minimal transposable element (TE) expansions have led to continually shrinking during evolution many lineages volant birds. Despite constraints genome size in birds, we identified multiple waves amplification TEs Piciformes (woodpeckers, honeyguides, toucans, barbets). Relative other bird species' genomic TE abundance (< 10% genome), found ∼17–30% content clades within Piciformes. Several families the retrotransposon superfamily chicken repeat 1 (CR1) expanded at least three different activity. most recent CR1 (∼4–7% genome) preceded bursts diversification woodpecker clade American barbets + toucans clade. Additionally, several thousand polymorphic insertions (hundreds per individual) closely related species. Woodpecker insertion polymorphisms maintained lower frequencies than single nucleotide indicating that purifying selection is acting against additional copies these elements impose fitness cost on their host. These findings provide evidence large scale ongoing activity avian despite continual constraint size.

Avian telencephalon and cerebellum volumes can be accurately estimated from digital brain endocasts

Biology Letters, Journal Year: 2025, Volume and Issue: 21(1)

Published: Jan. 1, 2025

For studies of the evolution vertebrate brain anatomy and potentially associated behaviours, reconstructions digital endocasts from computed tomography scans have revolutionized our capacity to collect neuroanatomical data. However, measurements must be validated as reflecting actual anatomy, which is difficult because collection soft tissue information through histology laborious time-consuming. In birds, reliability endocast volume proxies for two largest regions—the telencephalon cerebellum—remains despite their use proxies, e.g. cognitive performance or flight ability. We here dataset date, including 136 species 25 avian orders, compare surface area with volumes telencephalon, cerebellum whole-brain endocast. Using linear phylogenetically informed regression analyses, we demonstrate that surfaces are strongly correlated counterparts both absolute relative size. This provides empirical support using endocast-derived cerebellar telencephalic areas in existing future living extinct potential expand dinosaur—bird transition future.
