Habitat selection by the Pale-breasted Spinetail (Synallaxis albescens) at multiple spatial scales in the central Monte Desert, Argentina
(Csiro Publishing, 2012-05)
Habitat selection by birds is the result of hierarchical decisions that may be based on different cues at different spatial scales. However, studies rarely assess patterns of selection at multiple scales simultaneously in ...
Cost analysis of remotely sensed foraging paths in patchy landscapes with plant anti-herbivore defenses (Patagonia, Argentina)
(Springer, 2007-05)
We developed metrics at a landscape scale to evaluate the costs and rewards experienced by large herbivores while foraging in natural vegetation with patchy anti-herbivore plant structures. We show an application of these ...
Responses of vegetation to different land-use histories involving grazing and fire in the North-east Patagonian Monte, Argentina
(Australian Rangeland Society, 2013-06)
In arid and semiarid lands around the world, vegetation is distributed in patches within a bare soil matrix. Vegetation in the North-east Patagonian Monte, Argentina is a shrubland steppe, and patches are dominated by ...
Spatial patterns and chemical characteristics of root biomass in ecosystems of the Patagonian Monte disturbed by grazing
(Academic Press Ltd - Elsevier Science Ltd, 2007-07)
We hypothesized that the reduction in perennial-grass cover induced by grazing in shrublands would be associated with a reduction in fine-root biomass in the upper soil, an increase in the spatial heterogeneity of root ...
Carbono acumulado en la biomasa vegetal de la reserva de Villavicencio (Mendoza-Argentina)
(Sociedad Argentina de Botánica, 2013-12)
Carbon storage in the plant biomass of the Villavicencio Nature Reserve (MendozaArgentina). Nature reserves play a relevant role in carbon storage in arid lands. The vegetation of the Nature Reserve of Villavicencio stores ...
Distribución potencial de los bosques de Prosopis flexuosa en la Provincia Biogeográfica del Monte (Argentina)Potential distribution of Prosopis fexuosa woodland in the Monte desert (Argentina):
(Asociación Argentina de Ecología, 2014-08)
En las zonas áridas de Argentina, los bosques de Prosopis flexuosa son de suma importancia porque protegen el suelo en áreas con riesgo elevado de desertificación, y porque ofrecen diversos recursos a los pobladores locales ...
Finding woodlands in drylands: Bases for the monitoring of xeric open forests in a cloud computing platform
(Elsevier, 2021-04)
Conservation and sustainable management of woodlands in drylands is a priority at the global level considering the numerous benefits and ecosystem services they offer for local people. Sustainable use of forest resources ...
Análisis florístico y fitogeográfico de ambientes asociados al complejo de ciénagas de Zapatosa (Cesar) en el Caribe colombiano
(2012)
Se estudia la composición florística del complejo cenagoso de Zapatosa (Cesar, Colombia) y se analiza la distribución fitogeográfica de los taxones presentes. Los resultados obtenidos se comparan con la información existente ...
Cattle raising in central, semiarid rangelands of Argentina
(Elsevier, 2006-02)
Most rangelands are managed inappropriately in Argentina. This article provides some simple guidelines that can ensure a better grazing of rangeland vegetation and simultaneously increase beef production. Our main objective ...
Plant communities and phytogeographical units from NW San Juan Province (High Central Andes of Argentina)
(Conservatoire et Jardin Botaniques Ville Genève, 2010-04)
Vegetation of the High Central Andes of Argentina was studied in NW San Juan Province (MAB Reserve of San Guillermo) from a phytosociological point of view. Four new associations are proposed: two shrubland associations, ...
