Phylogenomics and biogeography of the world's thrushes (Aves,Turdus): new evidence for a more parsimonious evolutionary history

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2020, Volume and Issue: 287(1919), P. 20192400 - 20192400

Published: Jan. 22, 2020

To elucidate the relationships and spatial range evolution across world of bird genus Turdus (Aves), we produced a large genomic dataset comprising ca 2 million nucleotides for 100 samples representing 53 species, including over 2000 loci. We estimated time-calibrated maximum-likelihood multispecies coalescent phylogenies carried out biogeographic analyses. Our results indicate that there have been considerably fewer trans-oceanic dispersals within than previously suggested, such Palaearctic clade did not originate in America African was involved colonization Americas. Instead, our findings suggest dispersal from Western via Antilles to Neotropics might occurred single event, giving rise rich Neotropical diversity observed today, with no reverse or Africa. multilocus dataset, combined dense species-level sampling analysed under probabilistic methods, brings important insights into historical biogeography systematics, even scenario fast spatially complex diversification.

An ecological niche has been defined as an n-dimensional hypervolume formed by conditions and resources that species need to survive, grow, reproduce. In practice, such dimensions are measurable describe how share resources, which thought be a crucial mechanism for coexistence major driver of broad biodiversity patterns. Here, we investigate resource partitioning trophic interactions three sympatric, phylogenetically related morphologically similar thrushes (Turdus spp.). Based on one year data collected in southern Brazil, investigated using approaches: diet assessed fecal analysis, estimated stable isotopes blood mixing models, bipartite network analysis derived from direct model outputs. Approaches revealed the sympatric generalists feed diets, demonstrating high overlap. Fruits C3 plants were most important food items their networks, with wide links connecting thrush species. Turdus amaurochalinus T. albicollis had greatest isotopic overlap, 90% 20% respectively. There was key between these two species, shared preference fig tree fruits-Ficus cestrifolia (T.

Both visualized networks show food-consumers link strengths. This could useful other studies coupled particularly niches.

The explosive radiation, intense host-shifts and long-term failure to speciate in the evolutionary history of the feather mite genusAnalges(Acariformes: Analgidae) from European passerines

Zoological Journal of the Linnean Society, Journal Year: 2021, Volume and Issue: 195(2), P. 673 - 694

Published: July 10, 2021

Abstract Mites of the genus Analges (Acariformes: Analgidae) inhabit down feathers passeriform birds. The evolutionary history and co-phylogentic relationships between these mites their hosts are unknown. Our phylogenetic analysis supported monophyly genus, but it did not support previous taxonomic hypotheses subdividing into subgenera Analgopsis or arranging some species A. chelopus passerinus groups. Molecular data reveal seven new inhabiting Eurasian passerines existence several multi-host species. According to molecular dating, origin (c. 41 Mya) coincided with Eocene diversification Passerida Sylvioidea Muscicapoidea–Passeroidea. initial took place on Muscicapoidea clade, while remaining passerine superfamilies appear have been colonized because host-switching. Co-speciation appears be relatively common among hosts, most striking pattern in co-phylogenetic scenario involves numerous complete host-switches, spreads failures speciate. mechanism long-term gene-flow different populations is enigmatic difficult resolve. Probably, cases could transferred birds via used as nest material.

Published: May 3, 2022

Few studies on bird migration address altitudinal in South America, a regional-scale movement currently known for only nine species within the threatened Atlantic Forest biome. The Yellow-legged Thrush Turdus flavipes (YLTH) is one of such migrants thus far studied narrow gradient and which fruits are pointed as likely triggers its seasonal movements. Here, we expand this knowledge by testing hypotheses that arthropod fleshy fruit availabilities, climatic variables may all play roles abundance along broader (10-1,100 m asl) Forest. We estimated YLTH density food resource availability sites at three different altitudes. Besides supporting previous findings migratory behaviour, our reveal novel complex variation across altitudes, consistent with partial from higher Aside availability, rainfall also partially influenced new perspective species. providing picture YLTHs, conclude stressing need further understudied system birds including assessment general validity current mechanisms underlying interesting behaviour evolution.

Biologia Futura: rapid diversification and behavioural adaptation of birds in response to Oligocene–Miocene climatic conditions

Biologia Futura, Journal Year: 2020, Volume and Issue: 71(1-2), P. 109 - 121

Published: June 1, 2020

Abstract Our knowledge about the origin of landbirds (Telluraves) is increasing rapidly but new questions are arising because contradictory findings from previous studies. All major lineages in highly diverse clade Neoaves have a Gondwanan origin, although studies often disagree different sub-lineages. Nevertheless, understanding biogeographical histories these groups (e.g. Accipitriformes, Passeriformes) important when studying evolution variation life history and behavioural traits. Therefore, we would like to find answers such as which biogeographic changes affected radiation birds? When did most influential climatic events affect diversification What adaptations occurred response those large-scale changes? The orogenetic Asia South America formed specific corridors that enabled birds. habitat differentiation they caused during Oligocene–Miocene era made divergence birds possible through their adaptation newly available niches. Consequently, traits emerged adaptive outcomes foraging, nestling migratory behaviours.

Pressure for rapid and accurate mate recognition promotes avian‐perceived plumage sexual dichromatism in true thrushes (genus: Turdus)

Journal of Evolutionary Biology, Journal Year: 2022, Volume and Issue: 35(11), P. 1558 - 1567

Published: Oct. 5, 2022

Abstract Ecological conditions limiting the time to find a compatible mate or increasing difficulty in doing so likely promote evolution of traits used for species and recognition. In addition interspecific character displacement signalling identity, intraspecific that signal an individual's sex breeding status reduce challenge identifying conspecific should be more common migratory rather than sedentary species, with shorter seasons under high sympatry many closely related heterospecifics. Here, we tested this recognition hypothesis promoting plumage sexual dichromatism true thrushes ( Turdus spp.), large diverse genus passerine birds. We receptor‐noise limited models avian vision quantify avian‐perceived chromatic achromatic visual contrasts between male female patches influence season length, spatial distribution other on dichromatism. As predicted, found (1) thrush behaviour have greater non‐migratory (2) longer less dichromatism, (3) numbers is associated These results suggest social systems, including recognition, play prominent role thrushes.

Abstract The Fieldfare is a bird species widely distributed in the Palearctic region. In Hungary, considered as rare breeder and common, sometimes abundant migrant autumn spring, also winter visitor. It prone to invasion, since northern breeding populations leave sites large numbers only when available food inadequate or inaccessible birds. Most follow southern-southwestern migration pattern, course of their movement they migrating through Carpathian Basin. this study, we examined wintering an area southeast Hungary between 2004 2019. Data were collected beginning October middle April during that period saw Fieldfares total 416 times. addition description migration, effect weather on was investigated. According our results, appears disappears late March first half April. individuals migrate are likely belonging Central European population, while from November Scandinavian birds can be seen. maximum number observed different years showed significant differences, did patterns movements within seasons. relationship local has been demonstrated over several seasons, which typical with escape migration.
