Comparative phytolith analysis of Festuca (Pooideae: Poaceae) species native to Tierra del Fuego, Argentina
(National Research Council Canada-NRC Research Press, 2012-11)
Festuca L. is one of the most representative native grasses of Tierra del Fuego in the southernmost area of South America. In several patches, however, domestic cattle have overgrazed, causing loss or replacement by exotic ...
Phytolith analysis in Quaternary fluvial deposits (El Palmar Formation-Late Pleistocene) of the Uruguay River valley, Entre Ríos province, Argentina
(Pergamon-Elsevier Science Ltd, 2020-06)
The phytolith assemblages of the El Palmar Formation (Late Pleistocene) are presented together with general stratigraphic and sedimentological data. The El Palmar Formation represents a channel system of the Uruguay river ...
Phytolith analysis of Chusquea ramosissima Lindm. (Poaceae: Bambusoideae) and associated soils
(Pergamon-Elsevier Science Ltd, 2009-01)
Chusquea ramosissima Lindm. is dominant in the understory of the Misiones province forests (Argentina); it colonizes open natural areas and gaps created by timber extraction. The aim of this study is to analyze both the ...
Silica biomineralizations in Holocene peatlands and fossil peat layers from Tierra del Fuego, Argentina
(Pergamon-elsevier Science Ltd, 2013-01)
Phytolith analyses are practically absent from peatlands, except for studies developed on tropical mires and peat profiles. In Tierra del Fuego, Argentina, peatlands represent the largest surface coverage in the South ...
