AbstractThe latest publications on Sarcocornia taxonomy and phylogeny recognize six taxa in this genus the Iberian Peninsula: S. perennis, fruticosa, alpini, alpini subsp. carinata, hispanica, pruinosa. The present study represents a comprehensive revision of different Western Mediterranean Europe by means morphological, micromorphological phylogenetic internal transcribed spacer (ITS) analysis. Morphological data were studied from samples 113 populations coastal salt marshes inland pans...
The Tinto River (Huelva, Spain) constitutes a complex and singular system characterized by extreme acidity high concentrations of iron other metals (Cu, Co, Mn, Zn, Pb, As) its soils waters. Traditional mining activity the resulting intensive deforestation have eliminated natural vegetation. Communities endemic Erica andevalensis colonize fluvial terraces areas River, from drier to more humid soils, reaching optimum in proximity rivers streams. Concentrations 22 (S, K, Ca, Fe, Ni, Cu, As,...
Abstract This study presents a comprehensive revision of the genus Sarcocornia (Chenopodiaceae) on Iberian Peninsula based macromorphological, micromorphological and phylogenetic data, considering caryological, ecological biogeographical information. Three species have been identified Peninsula: perennis (Miller) A.J. Scott, fruticosa (L.) Scott alpini (Lag.) Rivas-Martínez. Several authors proposed that S. is specific subspecific rank perennis. Fuente, Rufo Sánchez-Mata recently described...
Abstract The relative concentration and distribution of nickel (Ni) in vegetative tissues (leaves, stems trichomes) reproductive organs (seeds) was studied using energy-dispersive X-ray microanalysis (EDXS) scanning electron microscopy (SEM) two previously Ni-hyperaccumulator subspecies Alyssum serpyllifolium Desf. growing naturally ultramafic soils the Iberian Peninsula: A. ssp. lusitanicum Dudley & P. Silva malacitanum Rivas Goday ex G. López. Both taxa showed that Ni accumulates...
Although biomineralization in plants is an important area of research, there very limited information. In this work, we report the location Na, K, Ca, Mg and Fe biominerals Sarcocornia pruinosa (Chenopodiacaeae), a halophyte species growing estuarine Río Tinto, extreme acidic environment. The soils Tinto basin are characterized by slightly pH high concentrations ions. They exposed to Atlantic Ocean tides that contribute increase pH, Na concentrations. aim work was characterize elemental...
A new species of Arthrocaulon Piirainen & G. Kadereit, A. meridionalis is described. This diploid taxon known from the islands Sicily and Sardinia circum-Mediterranean territories (from North Africa to Anatolian Peninsula in Turkey as far Persian Gulf on Asian continent). The distinctive macro-, micromorphological chorological features this are given.
This study deals with plant communities of the mining area Río Tinto basin, their relationship environment, specifically soils, and successional processes. The vegetation was studied by phytosociological methods. results reveal that current is mainly composed ten present a progressive regressive sequence constitutes series. actions in have led to loss original soils fast regression first colonizer stages. process entails diversity change Raunkier's life-form spectrum. Soil physical chemical...
Abstract Cynodon dactylon (L.) Pers. is a perennial rhizomatous grass (Poaceae), grown for cattle nutrition on the riverbanks of Río Tinto (Southwest Iberian Peninsula, Spain), highly acidic area with high concentrations iron (Fe) and other metals. This study focuses absorption, distribution, accumulation Fe in root, rhizome, leaves C. under controlled conditions. Plants collected from were Hoagland solution containing 500 mg kg –1 ferrous Fe. Samples up to 2 months after exposure analyzed...
The intensive study of the genera Microcnemum and Arthrocnemum based on their morphological anatomical characteristics phylogenetic relationships has led to a notable advance in knowledge both taxa, almost two centuries after publication. Morphology anatomy were analyzed using optical (OM) scanning (SEM) transmission (TEM) electron microscopy techniques. Phylogenetic reconstruction was done by Bayesian inference through ITS molecular marker. For first time, phylogeny is presented focused...
Pollen morphology of seven Alyssum L. taxa growing on serpentine soils in different places the European Mediterranean macrobioclimate territory were studied, described and compared. Cluster analysis was performed to show similarity between species their populations. The shape pollen grains varies among within same anther. are 3-colpate, prolate, with long narrow colpi reaching poles. ornamentation exine from micro-reticulate reticulate species. sterility/fertility also calculated. highest...
