The Extent of Infrastructure Causing Fragmentation in the Hydrocarbon Basin in the Arid and Semi-Arid Zones of Patagonia (Argentina)
(Multidisciplinary Digital Publishing Institute, 2019-10-25)
Fragmentation is a disruption in the connectivity of landscapes. The aims of this paper are (i) to quantitatively assess the fragmentation rates in three landscape units located in a hydrocarbon basin, and (ii) to model ...
Is the nitrification a redundant process in arid regions?: activity, abundance and diversity of nitrifiers microorganisms
(Soc Biolgia Chile, 2013-09)
We tested if the microbial functional redundancy concept (theory relating changes in ecosystem functioning by species loss) apply for changes in the ammonium-oxidizing community (nitrifi er bacteria) due to: a) grazing ...
Archetypal temporal dynamics of arid and semi-arid rangelands
(Elsevier Science Inc., 2021-03)
The way in which temporal dynamics structure ecological systems under the influence of a changing environment has long interested ecologists. Tackling the hierarchical structure of complex temporal patterns is a necessary ...
Aquatic macroinvertebrates from littoral vegetated lakes in arid Patagonia: the influence of fish introduction on community structure
(John Wiley & Sons Ltd, 2021-07)
Wetlands in arid regions are characterized by their great heterogeneity, often including endemic species that contribute to regional aquatic biodiversity. In the Patagonian steppe, most lakes are naturally fishless and ...
CALIBRACIÓN Y APLICACIÓN DEL ÍNDICE DE ARIDEZ DE De Martonne PARA EL ANÁLISIS DEL DÉFICIT HÍDRICO COMO ESTIMADOR DE LA ARIDEZ Y DESERTIFICACIÓN EN ZONAS ÁRIDASCalibration and application of the De Martonne aridity index for the analysis of hydric deficit as an estimator of aridity and desertification in arid areas

Drought propagation in semi-arid river basins in Latin America: Lessons from Mexico to the Southern Cone
(Molecular Diversity Preservation International, 2018-11)
Detecting droughts as early as possible is important in avoiding negative impacts on economy, society, and environment. To improve drought monitoring, we studied drought propagation (i.e., the temporal manifestation of a ...
Surface activity, sex ratio and diversity of scorpions in two different habitats in an Arid Chaco reserve, Argentina
(Springer, 2014-06)
Scorpions are one of the most important taxa of predators in terms of density, biomass, and diversity in various areas of the world. In this study, we compared population- and community-level data between a mature and a ...
