Sheep faeces decomposition and nutrient release across an environmental gradient in Southern Patagonia

Ecología Austral, 2017
In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock use, around 85% of the nitrogen

Fertile Osmundaceae from the Early Jurassic of Patagonia, Argentina

International Journal of Plant Sciences, 2012
Two new compression-impression species of the Osmundaceae described from reproductive and vegetative remains are erected for the first time from the Early Jurassic of Argentina. Todites cacereii sp. nov. and Osmundopsis rafaelii sp. nov. demonstrate that two main osmundaceous reproductive morphologies; i.e., differentiated reduced or unreduced fertile ...

Roadside raptor surveys in Valdes Peninsula (Patagonia, Argentina)

El Hornero, 2016
The Valdes Peninsula is a high-value natural area located on the Atlantic coast of the Argentine Patagonia. This research sought to survey raptor species of the peninsula, which has been little investigated. Roadside raptor surveys were carried out along a 451-km roadside transect in November 2012 and in April 2013.

A discrete event model for real time system simulation

Journal of Computer Science and Technology, 2012
In this work we present a discrete event model to design and implement a real time system simulator. This kind of software is useful to verify and evaluate algorithms and models, and to compute performance metrics. The discrete event model fits perfectly

Success of an exotic snail Physella acuta in anthropogenically impacted Patagonian streams

Biología Acuática
The expansion of exotic species is one of the greatest threats to biodiversity and is a significant component of global change that occurs at increasing rates due to the removal of natural barriers and the global transport of species. The snail Physella

Foliar water uptake and phyllosphere microbe colonization increase under higher soil nitrogen availability

Frontiers in Plant Physiology
Leaf water uptake (FWU) represents an alternative pathway to plant water acquisition that can have positive effects on water and carbon balance. Leaf surface traits including the phyllosphere microbes can affect the leaf wetness capacity and FWU.

Eimeriid Oocysts From Archaeological Samples in Patagonia, Argentina

Journal of Parasitology, 2008
Oocysts attributable to E. macusaniensis Guerrero et al. 1971, were found in coprolites and in archaeological sediments dating to the Holocene of Patagonia, Argentina. By means of a non-parametric regression using a generalized additive model, a significant relationship was found between the size of the oocysts and their antiquity.
