Oligo-Miocene radiation within South-west Pacific arc terranes underpinned repeated upstream continental dispersals in pigeons (Columbiformes)

Biological Journal of the Linnean Society, Journal Year: 2023, Volume and Issue: 138(4), P. 437 - 452

Published: March 11, 2023

Abstract Upstream colonizations from islands to continents have played an important role in two major global bird radiations: the oscine passerines and pigeons. Here, we investigate insular diversification upstream dispersal dynamics of pigeons (Columbiformes) within Indo-Australian Archipelago using a supermatrix fossil-calibrated phylogeny model-based biogeographical analyses. These analyses show that Melanesia, now centred on New Guinea considered separately Australia, been centre pigeon since Eocene–Oligocene transition (~34 Mya). Geological reconstructions are concordant suggesting arc terranes continental ribbon fragments underpin contemporary Melanesian region might formed extensive archipelagos for much Oligocene Miocene. also inferred functioned as net source lineages Asia especially Australia.

Birds and barriers: present and past seas are dominant correlates of avian turnover in the Indo-Australian Archipelago

The Indo-Australian Archipelago (IAA) is a geologically dynamic area of high biotic endemism that spans the continental shelves Sunda and Sahul intervening oceanic islands. We provide comprehensive quantitative assessment how bird communities are structured across IAA using beta diversity indices. focus on three key questions.

Beetle evolution illuminates the geological history of the World's most diverse tropical archipelago

The geologically‐complex Indo–Australian–Melanesian archipelago (IAMA) hosts extraordinarily high levels of species richness and endemism has long served as a natural laboratory for studying biogeography evolution. Nonetheless, its geological history the provenance evolution biodiversity remain poorly understood. Here, we provide scenario IAMA informed by time‐calibrated molecular phylogeny 1006 Trigonopterus weevils – an exceptionally diverse radiation regionally‐endemic flightless beetles. Moreover, performed statistical biogeographic analysis examined timing patterns in accumulation lineages residing priori‐defined geographic units comprising IAMA. We estimate that originated Australia during early Paleogene.

Phylogenomic and mitogenomic data can accelerate inventorying of tropical beetles during the current biodiversity crisis

eLife, Journal Year: 2021, Volume and Issue: 10

Published: Dec. 20, 2021

Conservation efforts must be evidence-based, so rapid and economically feasible methods should used to quantify diversity distribution patterns. We have attempted overcome current impediments the gathering of biodiversity data by using integrative phylogenomic three mtDNA fragment analyses. As a model, we sequenced Metriorrhynchini beetle fauna, sampled from ~700 localities in continents. The species-rich dataset included ~6500 terminals, ~ 1850 putative species delimited at 5% uncorrected pairwise threshold, possibly ~1000 them unknown science. Neither type could alone answer our questions on phylogeny. backbone enabled delimitation robustly defined natural genus-group units that will inform future research. Using constrained analysis, identified spatial structure diversity, very high species-level endemism, hotspot New Guinea. suggest focused field research subsequent laboratory bioinformatic workflow steps would substantially accelerate inventorying any hyperdiverse tropical group with several thousand species. outcome scaffold for incorporation further environmental sequencing ecological studies. database sequences set benchmark spatiotemporal evaluation biodiversity, support evidence-based conservation planning, provide robust framework systematic, biogeographic, evolutionary
