Changes in soil organic matter associated with afforestation affect erosion processes: The case of erodible volcanic soils from Patagonia
(Elsevier Science, 2021-12)
Large areas of the Patagonian Andean Region with high potential for planting fast-growing exotic conifers, based on the volcanic nature of its soils, are affected by erosion processes. This study aimed to analyse the effects ...
Liver ethoxyresorufin-O-deethylase and brain acetylcholinesterase in two freshwater fish species of South America; the effects of seasonal variability on study design for biomonitoring
(Academic Press Inc Elsevier Science, 2012-12)
Responses at low levels of biological organization to evaluate environmental changes and water quality have been used for many years. South America is no different, and recently biochemical endpoints in fish have been used ...
A study on the fragmentation of saltating particles along the fetch distance during wind erosion
(Elsevier Science, 2018-12)
PM10 emission largely depends on the characteristics of the saltation process, which involves the movement of aggregate and isolated particles. Studies analyzing the relationship between the fragmentation of saltating ...
Determination of the wind-erodible fraction of soils using different methodologies
(Elsevier Science, 2007-05)
The wind-erodible fraction of the soil (EF) (percentage of aggregates < 0.84 mm in diameter) is a key parameter to estimate the soil susceptibility to wind erosion. The standard method for EF determination is the dry sieving ...
Soil erodibility and quality of volcanic soils as affected by pine plantations in degraded rangelands of NW Patagonia
(Springer, 2016-05)
NW Patagonia in Argentina has high potential for planting fast-growing exotic conifers, supported by its volcanic soils. Nonetheless, many aspects related to the effects of pine plantations on soil are still unknown. We ...
Soil erodibility and quality of volcanic soils as affected by pine plantations in degraded rangelands of NW Patagonia
(2016-08)
NW Patagonia in Argentina has high potential for planting fast-growing exotic conifers, supported by its volcanic soils. Nonetheless, many aspects related to the effects of pine plantations on soil are still unknown. We ...
Soil dry aggregate stability and wind erodible fraction in a semiarid environment of Argentina
(Elsevier Science, 2010-10)
The size and stability of soil aggregates are primary factors that affect the soil susceptibility to wind erosion. Relationships among several soil properties and both the wind erodible fraction (EF) and the dry aggregate ...
Variación estructural en poblaciones de Denmoza rhodacantha (Cactaceae) sobre laderas de montañas en Mendoza, ArgentinaStructural variation in Denmoza rhodacantha (Cactaceae) populations on mountain slopes in Mendoza, Argentina
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2007-12)
Denmoza rhodacantha (Salm-Dyck) Britton & Rose, un cactus endémico de Argentina, tiene un gran número y densidad de población sobre laderas erosionadas de montañas más que en laderas no erosionadas. Para verificarlo se ...
Soil coverage evolution and wind erosion risk on summer crops under contrasting tillage systems
(Elsevier, 2015-03)
The effectiveness of wind erosion control by soil surface conditions and crop and weed canopy has been well studied in wind tunnel experiments. The aim of this study is to assess the combined effects of these variables ...
