Parasite diversification is influenced by many of the same factors that affect speciation free-living organisms, such as biogeographic barriers. However, ecology and evolution host lineage also has a major impact on parasite speciation. Here we explore interplay between biogeography host-association pattern in group ectoparasitic lice (Insecta: Phthiraptera: Penenirmus) feeds feathers woodpeckers, barbets, honeyguides (Piciformes) some songbirds (Passeriformes). We use whole genome sequencing 41 ingroup 12 outgroup samples to develop phylogenomic dataset DNA sequences from reference set 2395 single copy ortholog genes, for total nearly four million aligned base positions.

The genome organization of woodpeckers has several distinctive features e.g., an uncommon accumulation repetitive sequences, enlarged Z chromosomes, and atypical diploid numbers. Despite the large diversity species, there is a paucity detailed cytogenomic studies for this group we thus aimed to rectify this.

A flicker of hope: Genomic data distinguish Northern Flicker taxa despite low levels of divergence

Ornithology, Journal Year: 2018, Volume and Issue: 135(3), P. 748 - 766

Published: June 6, 2018

Next-generation sequencing technologies are increasingly being employed to explore patterns of genomic variation in avian taxa previously characterized using morphology and/or traditional genetic markers. The hybridization dynamics the Northern Flicker complex have received considerable attention, primarily due conspicuous plumage differences among these birds and geographically extensive hybrid zone between Red-shafted (Colaptes auratus cafer) Yellow-shafted auratus) flickers Great Plains region North America. However, no molecular techniques been able differentiate 2 morphologically well-defined from one another, or conclusively closely related Gilded chrysoides).

Evolutionary and Biomechanical Basis of Drumming Behavior in Woodpeckers

Understanding how and why behavioral traits diversify during the course of evolution is a longstanding goal organismal biologists. Historically, this topic examined from an ecological perspective, where thought to occur in response selection pressures that arise through different social environmental factors. Yet physiology biomechanics also play role process by defining types are more or less likely arise. Our paper explores interplay between ecological, physiological, mechanical factors shape elaborate display woodpeckers called drum. Individuals produce behavior rapidly hammering their bill on trees habitat, it serves as aggressive signal territorial encounters. We describe components display—namely, speed (bill strikes/beats sec –1 ), length (total number beats), rhythm—differentially evolve sexual male-male competition, whereas other appear evolutionarily static, possibly due morphological physiological constraints. synthesize research related principles avian muscle ecology guide inferences about biomechanical basis woodpecker drumming. aim introduce ideal study system relates born

Convergent genomic signatures of local adaptation across a continental-scale environmental gradient

Convergent local adaptation offers a glimpse into the role of constraint and stochasticity in adaptive evolution, particular extent to which similar genetic mechanisms drive common selective forces. Here, we investigated genomics two nonsister woodpeckers that are codistributed across an entire continent exhibit remarkably convergent patterns geographic variation. We sequenced genomes 140 individuals Downy ( Dryobates pubescens ) Hairy villosus used suite genomic approaches identify loci under selection. showed evidence genes have been targeted by selection response shared environmental pressures, such as temperature precipitation. Among candidates, found multiple putatively linked key phenotypic adaptations climate, including differences body size (e.g., IGFPB plumage MREG ). These results consistent with constraints limiting pathways broad climatic gradients, even after backgrounds diverge.

Rapid Laurasian diversification of a pantropical bird family during the Oligocene–Miocene transition

Published: Jan. 16, 2019

Disjunct, pantropical distributions are a common pattern among avian lineages, but disentangling multiple scenarios that can produce them requires accurate estimates of historical relationships and timescales. Here, we clarify the biogeographical history family trogons (Trogonidae) by re‐examining their phylogenetic divergence times with genome‐scale data. We estimated trogon phylogeny analysing thousands ultraconserved element (UCE) loci from all extant genera concatenation coalescent approaches. then time frame for diversification using MCMCTree fossil calibrations, after which performed ancestral area estimation BioGeo BEARS . recovered first well‐resolved hypothesis genera.

Selection for Rhythm as a Trigger for Recursive Evolution in the Elaborate Display System of Woodpeckers

The American Naturalist, Journal Year: 2019, Volume and Issue: 195(5), P. 772 - 787

Published: Dec. 18, 2019

Evolution is never truly predictable, in part because the process of selection recursive: it operates on its own output to generate historical contingencies, so emergent traits can reshape how others evolve future. Studies rarely attempt directly trace recursion underlies present-day phenotypic pattern a macroevolutionary basis. To address this gap, we examined different regimes—each operating timescale—guide evolution woodpecker drum display. Approximately 200 species with distinctive speed and length, which are important for territorial competition. We discovered remarkable variation rhythm, some drumming at constant rates changing along range mathematical functions. Rhythm undergoes divergent character displacement among sympatric sister species, that wanes as other reproductive boundaries emerge over time. Tracing recursive effects process, found modifying rhythm may then potentiate or constrain speed/length elaboration. Additionally, increased sexual size dimorphism predicts emergence rhythms associated constrained evolutionary speed/length, implying also itself. Altogether, our findings illustrate introduces contingencies allow diverse phenotypes arise from similar regimes.

Performance of a points-based scoring system for assessing species limits in birds

Ornithology, Journal Year: 2021, Volume and Issue: 138(2)

Published: April 6, 2021

Abstract Species are fundamental to biology, conservation, and environmental legislation; yet, there is often disagreement on how where species limits should be drawn. Even sophisticated molecular methods have limitations, particularly in the context of geographically isolated lineages or inadequate sampling loci. With extinction rates rising, needed assess rapidly but robustly. Tobias et al. devised a points-based system compare phenotypic divergence between taxa against level sympatric species, establishing threshold guide taxonomic assessments at global scale. The method has received mixed reception. To evaluate its performance, we identified 397 novel splits from 328 parent made by application criteria (in 2014‒2016) searched for subsequent publications investigating same with and/or data. Only 71 (18%) 60 since been investigated independent studies, suggesting that publication underpinned 2014–2016 accelerated decisions least 33 years.
