Pine afforestation affects key primary producers in mountain grassland streams in Córdoba, Argentina
(Royal Society of New Zealand, 2017-10)
We evaluated changes in benthic algal community in grassland mountain streams converted to exotic pine afforestation. Three headwater streams draining grasslands and three draining plantations of Pinus elliottii were ...
Environmental Conditions and Grazing Exerted Effects on Arbuscular Mycorrhizal in Plants at Southern Patagonia Rangelands
(Elsevier, 2022-03)
Arbuscular mycorrhizal (AM) fungi play a major role in maintaining ecosystem functions. AM fungi are found in most ecosystems including rangelands currently under increasing pressures from human activities. Southern Patagonia ...
Components of woody plant diversity in semi-arid Chaco forests with heterogeneous land use and disturbance histories
(Academic Press Ltd - Elsevier Science Ltd, 2012-10)
We assessed components of woody plant diversity within and between 16 sites dispersed across the nearly 200,000 ha of the Semi-arid Chaco vegetation of the Copo Conservation Unit, northern Argentina. Argentina's Semi-arid ...
Relationships between landscape features, soil properties, and vegetation determine ecological sites in a semiarid savanna of central Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2020-02)
Semiarid grasslands are still managed without considering site-specific differences in productivity. A better understanding of spatial heterogeneity would improve land management and might avoid desertification in semiarid ...
Wetlands of the Magellanic Steppe (Tierra del Fuego, Argentina)
(Springer, 2009-09)
Our main objective was to classify vegetation and soils of wetlands in northern Tierra del Fuego (Argentina) along a latitudinal precipitation gradient within the Magellanic Steppe Zone. We presented the first detailed ...
Effect of defoliation frequency on Rytidosperma virescens plants and arbuscular mycorrhizal fungi colonization
(Elsevier, 2022-06-09)
Rangelands provide different ecosystem services to satisfy human needs. Although grazing management in southern Patagonia is mostly characterized by extensive continuous grazing, rotational grazing management may improve ...
Relationship between vegetation assemblages and modern pollen in semiarid environments of Jujuy, northwestern Argentina
(American Association of Stratigraphic Palynologists Foundation, 2019-07)
Steppes and grasslands of semiarid environments in the Central Andes are poorly understood in fossil records due to the lack of modern pollen–vegetation studies. This paper is focused on a systematic analysis of the modern ...
Dung beetles increase greenhouse gas fluxes from dung pats in a north temperate grassland
(American Society of Agronomy, 2019-05)
Soil fauna plays a critical role in various ecosystem processes, but empirical data measuring its impact on greenhouse gas (GHG) emissions from rangelands are limited. We quantified the effects of dung beetles on in situ ...
