Arbuscular mycorrhizal colonization of vascular plants from the Yungas forests, Argentina
(EDP Sciences, 2007-10)
In Argentina, the Yungas forests are among the ecosystems most affected by human activity, with loss of biodiversity. To assess the mycorrhizal status in these ecosystems, the roots of 41 native plant species belonging to ...
Vascular plant species of the floating vegetation rafts from the Río de la plata (Argentina)Especies de plantas vasculares de las balsas de vegetación flotantes del Río de la Plata (Argentina)
(Jardim Botanico do Rio de Janeiro. Instituto de Pesquisas, 2018-10)
En los ríos sudamericanos, Eichhornia crassipes y otras plantas flotantes se entrelazan y forman balsas flotantes conocidas comúnmente como “camalotales” especialmente abundantes durante los períodos de inundación. Durante ...
Biogeographical relationships and new regionalisation of high-altitude grasslands and woodlands of the central Pampean Ranges (Argentina), based on vascular plants and vertebrates
(Csiro Publishing, 2017-05)
Evolutionary biogeography aims to provide a hierarchical system of biotic regionalisation for areas of the Earth that correspond to natural areas related by their common evolutionary history. In this context, the central ...
Spray with plant growth regulators at full bloom may improve quality for storage of ’Superior Seedless’ table grapes by modifying the vascular system of the bunch
(Elsevier, 2021-06)
The quality traits of table grape most appreciated by the consumers are berry size, bunch architecture, and freshness appearance (especially after post-harvest cold storage). Loss of bunch freshness reduces the value and ...
El origen y diversificación del crecimiento cambial atípico en plantas fósiles: procesos del desarrollo involucradosOrigin and diversification of atypical cambial growth in fossil plants: developmental processes involved
(Sociedad Argentina de Botánica, 2012-06)
En el registro fósil encontramos una serie de morfologías, cuyo origen sólo puede ser inferido a partir de los estudios ontogenéticos actualistas. De este modo, la comprensión de los procesos del desarrollo y el patrón ...
Impacto del fuego sobre la vegetación no vascular del suelo: un caso de estudio en los bosques de Polylepis australis (Rosaceae) del centro de ArgentinaFire impact on non vascular vegetation on soil: a case of study on Polylepis australis (Rosaceae) forests from central Argentina
(Fundación Miguel Lillo, 2019-12-07)
La vegetación no vascular está formada por líquenes, musgos, algas y cianobacterias tanto epífitas, como creciendo sobre el suelo. El objetivo de este trabajo fue estimar los cambios producidos por el fuego en la cobertura ...
Recovery of understory assemblage along 50 years after shelterwood cut harvesting in Nothofagus pumilio Southern Patagonian forests
(Elsevier Science, 2019-07)
Harvesting modifies the understory due to changes in the overstory structure, microclimate and soil properties. The impact is directly related to the harvesting intensity, although studies are usually developed in logged ...
Effects of biological soil crust and water availability on seedlings of three perennial Patagonian species
(Academic Press Ltd - Elsevier Science Ltd, 2016-02)
Biological soil crusts are communities composed of mosses, lichens and cyanobacteria. They cover a large portion of the arid and semiarid regions of the world and play key roles in nutrient cycles and soil erosion diminution. ...
Defining novel plant polyamine oxidase subfamilies through molecular modeling and sequence analysis
(BioMed Central, 2019-01)
Background: The polyamine oxidases (PAOs) catabolize the oxidative deamination of the polyamines (PAs) spermine (Spm) and spermidine (Spd). Most of the phylogenetic studies performed to analyze the plant PAO family took ...
