Broeggeria Walcott and other upper Cambrian and Tremadocian linguloid brachiopods from NW Argentina
(John Wiley & Sons Ltd, 2017-03)
The Broeggeria assemblage is a peculiar brachiopod association that has been recorded mainly from Tremadocian black shales of Baltoscandia, the Anglo-Welsh Basin, Nova Scotia, South Urals and Kazakhstan. Here, we report a ...
Compression map: Improved means for studying Carboniferous foliage
(Atlantic Geoscience Society, 2013-08)
A medullosalean-pteridosperm specimen, 22 cm long, from the Sydney Coalfield, Nova Scotia, Canada, illustrates the advantage of studying the fossilization history of compressed foliage freed from the rock matrix by ...
Intertidal mussels as ecosystem engineers: their associated invertebrate biodiversity under contrasting wave exposures
(Springer Berlin Heidelberg, 2014-02)
Mussels often act as ecosystem engineers in rocky intertidal habitats, favoring the occurrence of many small invertebrates by increasing habitat complexity and improving local environmental conditions. This study tests the ...
Chemometric study of structural groups in medullosalean foliage (Carboniferous, fossil Lagerstätte, Canada): Chemotaxonomic implications
(Elsevier Science, 2015-01)
A larger chemometric study (data derived from Fourier transform infrared spectroscopy-FTIR interpreted by principal component analysis) is undertaken involving species (numbers bracketed) from the four medullosalean families ...
Remineralization of organic carbon in eastern Canadian continental margin sediments
(Deep-Sea Research Part II: Topical Studies in Oceanography, 2000)
Undisturbed sediment samples were collected for chemical analyses at six sites during winter and summer cruises to the eastern Canadian continental margin. Micro-electrode oxygen profiles were obtained in freshly collected ...
PISA 2015 Results Volume IV : Students' Financial Literacy
(OECD, 2017)
Financial literacy is now globally recognised as an essential life skill. Globalisation and digital technologies have made financial services and products more widely accessible and at the same time more challenging. Many ...
The last major earthquakes along the Magallanes-Fagnano fault system recorded by disturbed trees (Tierra del Fuego, South America)
(Wiley, 2014-12)
Forests situated above active fault zones may record hillslope evolution, thus holding information about recent seismic events. Lenga trees (Nothofagus pumilio) extend across the Magallanes-Fagnano fault system (MFFS), the ...
The opening of the Magellan Strait and its geodynamic implications
(Wiley Blackwell Publishing, Inc, 2013-01)
The existence of a Neogene-Quaternary rift system responsible for the opening of the eastern Magellan strait has been one of the more peculiar tectonic features of the southernmost Andes since its discovery more than a ...
