Just out @ Proceedings of the Royal Society B Global biogeography since Pangaea Author(s) Sarah R. N. McIntyre, Charles H. Lineweaver, Colin P. Groves, Aditya Chopra Abstract: The break-up of the supercontinent Pangaea around 180 Ma has left its imprint on the global distribution of species and resulted in vicariance-driven speciation. Here, we test the idea that the molecular clock dates, for the divergences of species whose geographical ranges were divided,

On the News @ The Wire Title:  When Ostriches Called India Their Home Ranjini Raghunath Excerpt: “One hundred million years ago, the splitting of the supercontinent Gondwanaland scattered flightless birds across the landmasses: Rheas in South America, emus in Australia-Antarctica and ostriches and elephant birds in Indo-Madagascar. When India later split from Madagascar and slammed into Asia, ostriches hitched along and lived in the sub-continent for a while, before trekking across

Just out @ Journal of Biogeography In and out of the Neotropics: historical biogeography of Eneopterinae crickets Author(s) Natállia Vicente, Gael J. Kergoat, Jiajia Dong, Karla Yotoko, Frédéric Legendre, Romain Nattier, Tony Robillard Abstract: Aim | Multiple biogeographical scenarios involving vicariance and different colonization routes can explain disjunct species distributions in the Southern Hemisphere. Here, we tested several alternative hypotheses in Eneopterinae crickets, a diverse subfamily presenting a disjunct worldwide distribution.

Just out | First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications @ Journal of Paleontology

Just out @ Journal of Paleontology First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications Author(s) Marcela Cichowolski, Juan J. Rustán Abstract: Devonian bactritids are described for the first time from South America. They come from siliciclastic rocks of the Talacasto Formation in the Precordillera Basin, west-central Argentina. The host strata span the Lochkovian–Emsian and contain other non-ammonoid cephalopods as well, thus refuting the alleged virtual absence

Just out @ Journal of Asian Earth Sciences Upper Triassic reef coral fauna in the Renacuo area, northern Tibet, and its implications for palaeobiogeography Author(s) Jingfang Bo, Xunlian Wang, Jinhan Gao, Jianxin Yao, Genhou Wang, Engang Hou Abstract: Upper Triassic reef corals from the Riganpeicuo Formation in northern Tibet represent important scleractinian coral fauna that help explain the palaeobiogeography of the eastern Tethys region during the Late Triassic period. The corals

On the News @ El Dia Title:  La Patagonia tenía un mar en el medio y estaba mucho más al Sur Excerpt: “Que hace más de 200 millones de años atrás el planeta era distinto, era algo sabido. Pero ahora, un estudio de investigadores argentinos y estadounidenses encontró que nuestra región patagónica estaba más al sur del emplazamiento que actualmente tiene, y que estaba separada del continente por un mar.

Agora, um novo estudo sugere que uma grande parte da floresta foi duas vezes inundada pelo Mar do Caribe há mais de 10 milhões de anos, criando um curto mar interior que impulsionou

Ferguson, Molly M. McDonough, Gema I. Guerra, Margaret Rheude, Jerry W. Dragoo, Loren K. Ammerman, Robert C. Dowler Abstract: We analyzed phylogeographic patterns in the western spotted skunk, Spilogale gracilis Merriam, 1890 (Carnivora: Mephitidae) in relation to historical events

Just out @ BMC Evolutionary Biology Phylogeny, divergence time and historical biogeography of Laetiporus (Basidiomycota, Polyporales) Author(s) Jie Song and Bao-Kai Cui Abstract: Background The aim of this study was to characterize the molecular relationship, origin and historical biogeography of the species in important brown rot fungal genus Laetiporus from East Asia, Europe, Pan-America, Hawaii and South Africa. We used six genetic markers to estimate a genus-level phylogeny including (1)

Wattier Abstract: The Balkans are a major biodiversity and endemism hotspot, worldwide. Among the freshwater biota, amphipods are known for their high cryptic diversity. However, little is known about the temporal and paleogeographic aspects of
