Bringing together evolution on serpentine and polyploidy: spatiotemporal history of the diploid-tetraploid complex of Knautia arvensis (Dipsacaceae).

open access: yesPLoS ONE, 2012
Polyploidization is one of the leading forces in the evolution of land plants, providing opportunities for instant speciation and rapid gain of evolutionary novelties.

Serpentine Soils [PDF]

open access: yes, 2014
Serpentine soils are weathered products of a range of ultramafic rocks composed of ferromagnesian silicates. Serpentine more accurately refers to a group of minerals, including antigorite, chrysotile, and lizardite, in hydrothermally altered ultramafic ...

Flowering time evolution is independent of serpentine tolerance in the California flora

open access: yesEcosphere, 2017
Comparative phylogenetic tests have been only recently applied to the many hypotheses about the role ultramafic (serpentine) soils play in the evolution and ecology of regional floras.

Diagenesis of the Sedimentary Fe–Ni Deposits of Euboea: Evidence Based on Phyllosilicate Mineralogy

open access: yesMaterials Proceedings, 2021
A set of samples with different textures from the sedimentary Fe–Ni deposits of Central Euboea, Greece, were studied with XRD and SEM-EDS to investigate the relationships between phyllosilicates present.

2-hydroxyphosphonoacetic Acid to Eliminate the Adverse Effect of Serpentine on Chalcopyrite Flotation

open access: yesKuangchan zonghe liyong
This is an article in the field of mineral processing engineering. For the flotation of sulfide ores whose gangue mineral is serpentine, serpentine can deteriorate the flotation of sulfide ores due to its easy mudification.

Giant serpentine aneurysms [PDF]

open access: yesNeurosurgical Focus, 2009
Segal and McLaurin first described giant serpentine aneurysms, based on their distinct angiographic features, in 1977. These lesions are ≥ 25 mm, partially thrombosed aneurysms with a patent, serpiginous vascular channel that courses through the aneurysm.
