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 ...
Variation of morphological and chemical traits in sexes of the dioecious perennial grass Poa ligularis in relation to shrub cover and aridity in Patagonian ecosystems
(Springer Tokyo, 2016-01)
Sexes of dioecious species may have dimorphic responses to environmental variation due to differences in resource requirements and reproductive costs. We analyzed the effect of aridity/relative shrub cover, and vicinity ...
Degradation and recovery processes in semi-arid patchy rangelands of northern Patagonia, Argentina
(Wiley, 2013-08)
Vegetation in many arid and semiarid shrublands is frequently arranged in patches with high plant-cover (shrub patches) interspersed in a low-cover herbaceous matrix (inter-shrub areas). We hypothesized that (a) livestock ...
Regional productivity mediates the effects of grazing disturbance on plant cover and patch-size distribution in arid and semi-arid communities
(Wiley Blackwell Publishing, Inc, 2018-08)
Patch‐size distribution and plant cover are strongly associated to arid ecosystem functioning and may be a warning signal for the onset of desertification under changes in disturbance regimes. However, the interaction ...
Rodent middens, a new method for Quaternary research in arid zones of South America Paleomadrigueras de roedores, un nuevo método para el estudio del Cuaternario en zonas áridas de Sudamérica
(2002)
In arid and semi-arid regions of South America, historical evidence for climate and vegetation change is scarce despite its importance for determining reference conditions and rates of natural variability in areas susceptible ...
Localized vegetation patterns, fairy circles, and localized patches in arid landscapes
(American Physical Society, 2015)
We investigate the formation of localized structures with varying widths in one- and two-dimensional systems.
The mechanism of stabilization is attributed to strongly nonlocal coupling mediated by a Lorentzian type ...
Coevolution of hydrodynamics, vegetation and channel evolution in wetlands of a semi-arid floodplain
(EGU General Assembly 2015, 2020)
