Diversity of phenolic compounds and plant traits in coexisting Patagonian desert shrub species of Argentina
(Springer, 2013-09)
Desert shrubs often accumulate different types of phenolic compounds but what determines the amount and diversity of these compounds is an issue scarcely explored. The aim of this study was to assess differences in the ...
Shrub biomass estimation in the semiarid Chaco forest: a contribution to the quantification of an underrated carbon stockShrub biomass estimation in the semiarid Chaco forest: a contribution to the quantification of an underrated carbon stock
(Edp SciencesEdp Sciences, 2013-03)
Abstract & Context The quantification of biomass of woody plants is at the basis of calculations of forest biomass and carbon stocks. Although there are well-developed allometric models for trees, they do not apply ...

Effects of forest preservation, livestock exclusion and use of shrubs as potential nurses on planting success of an endangered tree
(Wiley Blackwell Publishing, Inc, 2021-05-27)
Domestic livestock are widespread in seasonally dry forests, likely causing forest degradation and limiting tree seedling establishment. Shrubs can play an important role in facilitating tree regeneration, by protecting ...
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 ...
A complex interaction networks controls coexistence and relative abundances in grass-shrub Patagonian steppes
(Wiley, 2014-02)
1. The coexistence of shrubs and grasses has intrigued ecologists for the past century, and the conundrum of shrub-grass coexistence is at the core of debates on the functioning of semi-arid ecosystems. Here, we explored ...
Conspecific leaf litter and root competition inhibits shrub emergence in the Patagonian steppe
(Springer, 2019-09)
A critical stage in the establishment of new individuals is seedling emergence and litter is a main factor affecting this stage. Recent research found that adults of Chuquiraga avellanedae are overdispersed. Among several ...
Plant production along a grazing gradient in a semiarid Patagonian rangeland, Argentina
(Springer, 2016-12)
Patagonian rangelands have been grazed by sheep since early twentieth century. However, there is still a degree of uncertainty regarding how production of grass and shrub species changes along a grazing gradient. The study ...
Leaf litterfall patterns of perennial plant species in the arid Patagonian Monte, Argentina
(Springer, 2010-02)
The objective of this study was to investigate the variation in leaf litterfall patterns of desert plant species in relation to the intra- and interannual variation of precipitation. We collected the leaf litterfall of 12 ...
