Rapid recovery of Patagonian plant–insect associations after the end-Cretaceous extinction
(Springer Nature, 2016-11)
The Southern Hemisphere may have provided biodiversity refugia after the Cretaceous/Palaeogene (K/Pg) mass extinction. However, few extinction and recovery studies have been conducted in the terrestrial realm using well-dated ...
Mass extinctions, galactic orbits in the solar neighborhood and the Sun: a connection?
(Guarujá, 2014-03-14)
The orbits of the stars in the disk of the Galaxy, and their passages through the Galactic spiral arms, are a rarely mentioned factor of biosphere stability which might be important for long-term planetary climate evolution, ...
The rise of the ruling reptiles and ecosystem recovery from the Permo-Triassic mass extinction
(The Royal Society, 2018-06)
One of the key faunal transitions in Earth history occurred after the Permo-Triassic mass extinction (ca 252.2 Ma), when the previously obscure archosauromorphs (which include crocodylians, dinosaurs and birds) become the ...
The earliest phases of high mass star formation, as seen in NGC 6334 by Herschel HOBYS
(EDP Sciences, 2017)
Aims. To constrain models of high-mass star formation, the Herschel-HOBYS key program aims at discovering massive dense cores (MDCs) able to host the high-mass analogs of low-mass prestellar cores, which have been searched ...
Megafauna decline have reduced pathogen dispersal which may have increased emergent infectious diseases
(2020-08-01)
The Late Quaternary extinctions of megafauna (defined as animal species > 44.5 kg) reduced the dispersal of seeds and nutrients, and likely also microbes and parasites. Here we use body-mass based scaling and range maps ...
THE EARLY STAGES OF STAR FORMATION IN INFRARED DARK CLOUDS: CHARACTERIZING THE CORE DUST PROPERTIES
(The American Astronomical Society, 2010-05-20)
Identified as extinction features against the bright Galactic mid-infrared background, infrared dark clouds (IRDCs)
are thought to harbor the very earliest stages of star and cluster formation. In order to better characterize ...
A colour-excess extinction map of the southern Galactic disc from the VVV and GLIMPSE surveys
(2019)
An improved high-resolution and deep A(Ks) foreground dust extinction map is presented for the Galactic disc area within 295 degrees less than or similar to l less than or similar to 350 degrees, -1.0 degrees less than or ...
Seed Dispersal Anachronisms: Rethinking the Fruits Extinct Megafauna Ate
(Public Library Science, 2008-03-05)
Background: Some neotropical, fleshy-fruited plants have fruits structurally similar to paleotropical fruits dispersed by megafauna (mammals > 10(3) kg), yet these dispersers were extinct in South America 10-15 Kyr BP. ...
