Gapped vegetation patterns: Crown/root allometry and snaking bifurcation
(Elsevier, 2020)
Nonuniform spatial distributions of vegetation in scarce environments consist of either gaps, bands often called tiger bush or patches that can be either self-organized or spatially localized in space. When the level of ...
Land use impact on chemical and spectroscopical characteristics of soil organic matter in an arid ecosystem
(Springer Heidelberg, 2016-05)
Soil organic matter (SOM) storage and composition in ecosystems may undergo change as a result of long-term livestock and soil cultivation, particularly in arid environments. In this work, we evaluated the alterations ...
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 ...
Patagonian Desert
(Elsevier, 2019)
The Argentinian Patagonia is a vast area (790,000-km2) of southern South America between 36° and 55°S. Almost 90% of the area is arid, semiarid or dry- subhumid (drylands) and covers important and heterogeneous ecological ...

The role of nurse functional types in seedling recruitment dynamics of alternative states in rangelands.
(2017-02-16)
In arid ecosystems, recruitment dynamics are limited by harsh environmental conditions and greatly depend on the net outcome of the balance between facilitation and competition. This outcome can change as a consequence of ...
Grazing pressure interacts with aridity to determine the development and diversity of biological soil crusts in Patagonian rangelands
(John Wiley & Sons Ltd, 2019-10)
Grazing is directly related to land degradation and desertification in global drylands. Grazing impacts on vascular plants, reasonably well-known, depend on its intensity and are modulated by local aridity conditions. ...
Interacting effects of soil degradation and precipitation on plant productivity in NE Patagonia, Argentina
(Taylor, 2016-01)
Our objective was to examine the effects of inter-annual variation of precipitation on productivity of two dominant species (Chuquiraga avellanedae, an evergreen shrub, and Nassella tenuis, a perennial grass) in two ...
Influence of condensed tannins from Brazilian semi-arid legumes on ruminal degradability, microbial colonization and ruminal enzymatic activity in Saanen goats
(Elsevier B.V., 2006-01-01)
The present study aimed at determining the influence of condensed tannins present in the Brazilian legume species Mimosa hostilis, Mimosa caesalpinifolia and Bauhinia cheilantha on ruminal degradability, microbial colonization ...
