Upstream colonisations from islands to continents have played an important role in the evolution of at least two major global bird radiations – oscine passerines and pigeons. Here we investigate dynamics insular diversification upstream dispersal pigeons(Columbiformes) within Indo-Australian Archipelago. Based on a supermatrix fossil-calibrated phylogeny model-based biogeographic analyses Melanesia, now centred New Guinea considered separately Australia, been centre pigeon since Eocene-Oligocene transition (~ 34 Ma). Geological reconstructions are concordant suggesting arc terranes continental ribbon fragments that underpin contemporary Melanesian region may formed extensive archipelagos separate main Australian landmass for much Oligocene Miocene. For most last 35 million years these inferred functioned as net source lineages Asia, especially Australia. However, probability evolutionary outcomes colonisation vary greatly across regions.

In contrast, terrestrial largely unable colonise while single early Australia preceded endemic

Explosive Cenozoic radiation and diversity-dependent diversification dynamics shaped the evolution of Australian skipper butterflies

Evolutionary Journal of the Linnean Society, Journal Year: 2022, Volume and Issue: 1(1)

Published: Jan. 1, 2022

Abstract Australia was predominantly tropical for most of the Early Cenozoic, then transitioned to a cooler and drier climate in Oligocene. In response this increasing aridity, some lineages either adapted xeric ecosystems, contracted increasingly fragmented mesic refugia, or went extinct. However, lack macroevolutionary studies at continental scale precludes better understanding Australian biodiversity patterns processes during Cenozoic. Here, we infer robust, dated phylogenomic tree radiation endemic butterflies, Trapezitinae skippers, test impact biotic abiotic drivers on Cenozoic diversification dynamics Australia. These butterflies originated Eocene (c. 42 Mya) biome exploded diversity cool, dry period Late Oligocene Miocene, experienced sharp deceleration speciation. Xeric ecosystems appear have been colonized more recently, supporting hypothesis arid semi-arid biomes as evolutionary sinks. Temperature-dependent phytophagy-dependent models received little support. Instead, find evidence diversity-dependent with declining likely linked limited ecological opportunities following rapid initial burst diversification.

How Do Genomic, Mitochondrial, and Morphological Data Contribute to the Linnean Classification of the Porrostomine Net-Winged Beetles (Coleoptera, Lycidae)?

Insect Systematics and Diversity, Journal Year: 2022, Volume and Issue: 6(5)

Published: Sept. 1, 2022

Abstract The Lycidae genera have seldom been tested with phylogenetic analyses. Therefore, we assembled genomic data to estimate the backbone of porrostomines, one Metriorrhynchina’s major clades. Further, mtDNA and morphology were employed assign 352 analyzed species genera. We present evidence for paraphyly Metriorrhynchus terminal position Porrostoma, revise generic classification, describe eight genera: Maraiakoreus gen. nov., Kuarhynchus Riedelrhynchus Bundikanus Yamarhynchus Bekorhynchus Sundarhynchus Isuarhynchus nov. synonymize Stadenus Waterhouse, 1879, syn.

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

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2021, Volume and Issue: unknown

Published: July 15, 2021

Abstract 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 ∼6,500 terminals, >2,300 putative species, more than half them unknown science. backbone enabled delimitation robustly defined natural units that will inform future research. Using constrained analysis, identified spatial structure α-diversity, very high species-level endemism, hotspot New Guinea, phylogenetic Sundaland. suggest ∼20 person months 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 data. database sequences could set benchmark spatiotemporal evaluation biodiversity, support evidence-based conservation planning, provide robust framework systematic, biogeographic, evolutionary studies.

What’s flashing in Kadamaian? A Note on Fireflies (Coleoptera: Lampyridae) in Kadamaian, Sabah

Journal of Tropical Biology & Conservation (JTBC), Journal Year: 2021, Volume and Issue: 18

Published: Oct. 15, 2021

A firefly survey was conducted in Podos, Melangkap Noriou and Pinolobu Kadamaian, Kota Belud during the Borneo Geographic Expedition Kadamaian 2019. total of 48 fireflies were collected representing at least seven species consisting mainly Luciola spp. a single individual Pyrocoelia sp. larva. Identification reveals that two samples are potentially new records to Borneo; cf. Aquilonia Medeopteryx sp., also niah as record for Sabah. Furthermore, four have unique morphological characters including potential samples. Fireflies caught various locations such near rubber plantations, trails rivers. Findings from this report expands distributional knowledge about Lampyridae Borneo.
