Evolutionary history of New World crakes (Aves: Rallidae) with emphasis on the tribe Laterallini

Zoologica Scripta, Journal Year: 2023, Volume and Issue: 52(4), P. 394 - 412

Published: April 7, 2023

Abstract New World crakes are intriguing, poorly known birds with cursorial cryptic habits; they belong to two unrelated tribes: Laterallini and Pardirallini. Recent genetic studies contributed the phylogenetic knowledge of these tribes, but a complete reconstruction is still missing. Here, we present most taxonomically dated gene‐based phylogeny crakes, an emphasis on Laterallini, including for first time sequences Coturnicops notatus , Laterallus levraudi L. jamaicensis tuerosi xenopterus . We used multilocus (mtDNA + nucDNA) analyses interpreted our results in light natural history group. Our novel show that: (1) sister leucopyrrhus ; (2) j. spilonota (3) C. clade that groups remaining black ( tuerosi, rogersi spilopterus ); (4) melanophaius conform recently diverged clade. Thus, indicate polyphyly this group, particularly and, time, some discrepancies previous stem from misidentified samples or Anurolimnas fasciatus. Finally, provide new preliminary insights into species limits taxa, specifically set stage integrative taxonomic assessments at generic level by incorporating (gene‐based) data.

Plio‐Pleistocene Environmental Changes Drove the Settlement of Aotearoa New Zealand by Australian Open‐Habitat Bird Lineages

Molecular Ecology, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT In a changing environment, vacant niches can be filled either by adaptation of local taxa or range‐expanding invading species. The relative tempo these patterns is key interest in the modern age climate change. Aotearoa New Zealand has been hotspot biogeographic research for decades due to its long‐term isolation and dramatic geological history. An island with high levels faunal endemicity, it system well suited studying effects situ evolution versus dispersal determining assemblages, while turbulent history provide valuable insights into evolutionary impacts environmental changes. Such investigations are urgent importance given predicted change human rapidly affecting environments globally. Here, we analyse divergence dates nearly all endemic bird species from their overseas relatives assess role changes driving speciation colonisation, special regard cooling during Pliocene Pleistocene. We uncover wave colonisation events Australian open‐habitat adapted since that peaked at beginning Furthermore, highlight an even distribution forest‐adapted through time, consistent millions years extensive forest cover. Finally, note parallels modern‐day establishment new populations Australia suggest this largely influenced anthropogenic land‐use patterns. This contributes growing body work recognising long‐lasting Pleistocene on Zealand's avifauna, reinforces biological invasions as response conditions.

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.

Phylogeny based on ultra-conserved elements clarifies the evolution of rails and allies (Ralloidea) and is the basis for a revised classification

Ornithology, Journal Year: 2021, Volume and Issue: 138(4)

Published: July 16, 2021

Abstract The rails (Family Rallidae) are the most diverse and widespread group in Gruiformes. Their extensive fossil history, global geographic distribution, tendency to rapidly evolve flightless species on islands make them an attractive subject of evolutionary studies, but rarity modern museum specimens so many rail has, until recently, limited scope molecular phylogenetics studies. As a result, classification remains one unsettled among major bird radiations. We extracted DNA from 82 species, including 27 study skins collected as long ago 1875, generated nucleotide sequences thousands homologous ultra-conserved elements (UCEs). Our phylogenetic analyses, using both concatenation multispecies coalescent approaches, resulted well-supported highly congruent phylogenies that resolve lineages reveal several currently recognized genera be polyphyletic. A fossil-calibrated time tree is well-resolved supports hypothesis split into 2 (subfamilies Himantornithinae Rallinae) ~34 mya, clade age estimates have wide confidence intervals. results, combined with results other recently published phylogenomics studies Gruiformes, form basis for proposed Rallidae recognizes 40 9 tribes.

Ancient DNA from the extinct Haitian cave-rail (Nesotrochis steganinos) suggests a biogeographic connection between the Caribbean and Old World

Biology Letters, Journal Year: 2021, Volume and Issue: 17(3)

Published: March 1, 2021

Worldwide decline in biodiversity during the Holocene has impeded a comprehensive understanding of pre-human and biogeography. This is especially true on islands, because many recently extinct island taxa were morphologically unique, complicating assessment their evolutionary relationships using morphology alone. The Caribbean remains an avian hotspot but was more diverse before human arrival Holocene. Among lineages enigmatic genus Nesotrochis, comprising three flightless species. Based morphology, Nesotrochis been considered aberrant rail (Rallidae) or related to flufftails (Sarothruridae). We recovered nearly complete mitochondrial genome steganinos from fossils, discovering that it not rallid instead sister Sarothruridae, volant birds now restricted Africa New Guinea, extinct, Aptornithidae Zealand. result suggests widespread highly dispersive most recent common ancestor group.

What passes through the extinction filter? Historical and contemporary patterns of vulnerability of the most extinction-prone bird family (Aves: Rallidae)

Cambridge Prisms Extinction, Journal Year: 2024, Volume and Issue: 2

Published: Jan. 1, 2024

Abstract Patterns of extinction risk can vary across taxa, with species some groups being particularly vulnerable to extinction. Rails (Aves: Rallidae) represent one the most extreme yet well-documented cases mass within a modern vertebrate group. Between 54 and 92% rail became extinct following waves human contact during both Holocene Anthropocene eras, third extant are currently threatened or near-threatened. Here, we (1) examine filters through consecutive contacts rails, investigating role intrinsic life-history traits (2) investigate drivers contemporary vulnerability. During recent wave extinction, found that body size was an important correlate extinctions, smaller larger bodied more likely become extinct. Island endemism small clutch were strongest predictors Overall, island endemic rails tend follow same trajectory as species, suffering mostly from invasive predators overhunting, but different targeted contemporarily compared past extinctions. Moreover, anthropogenic threats have created potential for new intricate pathways – ‘field bullets’ making future vulnerability potentially less predictable.
