Predicting green leaf proportion in ungrazed kleingrass (Panicum coloratum L.) in the semiarid Pampas Region of Argentina
(Instituto de Investigaciones Agropecuarias, 2013)
Green leaf proportion is an important factor affecting nutritive value, ingestive behavior and forage intake. Determination
of green leaf proportion by hand separation of plant samples is time consuming and expensive. The ...
Crop and Tillage Effects on Water Productivity of Dryland Agriculture in Argentina
(MDPI, 2013-03)
Rising demands for food and uncertainties about climate change call for a paradigm shift in water management with a stronger focus on rainfed agriculture. The objective here was to estimate water productivity of different ...
Decoupling of soil nutrient cycles as a function of aridity in global drylands
(Springer Nature, 2013-10-30)
The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked by primary production, respiration and decomposition in terrestrial ecosystems1 . It has been suggested that the C, N and P cycles ...
Hierarchical linear mixed models in multi-stage sampling soil studies
(Springer, 2013-06)
The issue of variances of different soil variables prevailing at different sampling scales is addressed. This topic is relevant for soil science, agronomy and landscape ecology. In multi-stage sampling there are randomness ...
Improving Estimation of Specific Surface Area by Artificial Neural Network Ensembles Using Fractal and Particle Size Distribution Curve Parameters as Predictors
(Springer, 2013)
Specific surface area (SSA) is one of the principal soil properties used in modeling soil processes. In this study, artificial neural network (ANN) ensembles were evaluated to predict SSA. Complete soil particle-size ...
microRNAs and the mammary gland: A new understanding of gene expression
(Genetics and Molecular Biology, 2013)
MicroRNAs (miRNAs) have been identified in cells as well as in exosomes in biological fluids such as milk. In mammary gland, most of the miRNAs studied have functions related to immunity and show alterations in their pattern ...

Las comunidades indígenas de la provincia de La Pampa, sobre todo las urbanas, al referirse a la puesta en práctica de una educación indígena diferencian dos instancias. Si la primera está relacionada con el proceso educativo ...
Parasitoidismo larval de oiketicus platensis (lepidoptera: psychidae) en el caldenal pampeano
(Fundación Miguel Lillo, 2013)
Desde el año 2006 se observa una invasión creciente de Oiketicus platensis (Berg 1883) en los bosques de caldén de la provincia de La Pampa. Los objetivos del presente trabajo es buscar parasitoides larvales, determinar ...
Continuous application of direct sowing: Traffic effect on subsoil compaction and maize (Zea mays L.) yields in Argentinean Pampas
(2013-11)
Our main objective was to evaluate the effect of subsoil compaction on maize (Zea mays L.) yields. This work was performed on clayey soil and on loamy Entic Haplustoll soil. Three types of direct sowing (DS) equipment ...
Assessment of the Effect of Silicon on Antioxidant Enzymes in Cotton Plants by Multivariate Analysis
(2013-11-04)
Silicon has been extensively researched in relation to the response of plants to biotic and abiotic stress, as an element triggering defense mechanisms which activate the antioxidant system. Furthermore, in some species, ...
