Problems concerning the extinction of organismsProblemas relativos às extinções de organismos
(Universidade de São Paulo, Instituto de Geociências, 1990)
Synthetic extinction maps around intermediate-mass black holes in Galactic globular clusters
(Oxford University Press, 2016-05)
During the last decades, much effort has been devoted to explain the discrepancy between the amount of intracluster medium (ICM) estimated from stellar evolution theories and that emerging from observations in globular ...
A new faunistic component of the Lower Triassic Panchet Formation of India increases the continental non-archosauromorph neodiapsid record in the aftermath of the end-Permian mass extinction
(Paleontological Society, 2021-11)
The fossil record of Early Triassic diapsids is very important to understand how the end-Permian mass extinction affected ecosystems and the patterns and processes involved in the subsequent biotic recovery. Vertebrate ...
Mass extinctions, galactic orbits in the solar neighborhood and the Sun: a connection?
(International Astronomical UnionFlorianópolis, 2013)
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 ...
G0.253+0.016: A centrally condensed, high-mass protocluster.
(The American Astronomical Society., 2014-04-25)
Despite their importance as stellar nurseries and the building blocks of galaxies, very little is known about the formation of the highest mass clusters. The dense clump G0.253+0.016 represents an example of a clump that ...
The long bar as seen by the VVV Survey. II. Star counts
(Edp Sciences S A, 2013-11)
Context. There is still some debate about the presence and the morphological properties of the long bar in the inner Galaxy. Aims: We investigate the morphological properties of the long Galactic bar using the VVV survey ...
Seed Dispersal Anachronisms: Rethinking the Fruits Extinct Megafauna Ate
(Public Library Science, 2014)
Defaunation in the Anthropocene
(Amer Assoc Advancement Science, 2014-07-25)
We live amid a global wave of anthropogenically driven biodiversity loss: species and population extirpations and, critically, declines in local species abundance. Particularly, human impacts on animal biodiversity are an ...
Prediction of offspring in extant and extinct mammals to add light on paleoecology and evolution
(Elsevier Science, 2016-07)
Reproductive strategies can be inferred from adult body mass, although offspring characteristics can give more accurate tools to predict life histories. In fossil mammals, adult body mass estimation incorporates error to ...
