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 ...
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 ...
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 ...
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 ...
Temporal fluctuation in shrub species preferences of two native rodents: The effect of infection status on habitat use
(Wiley-Blackwell, 2016)
Small mammals use plant species for gathering food resources and for shelter. Preferences for certain plant species are related to nutritional restrictions and behavioural patterns, which could be altered in the presence ...
The elusive quantifi cation of nitrogen fi xation in xeric shrubs: The case of Adesmia volckmanni, a Patagonian leguminous shrub
(Elsevier, 2014-06)
The comparison of 15N natural abundance (δ15N) between fixing and non-fixing reference species, is the most feasible method for nitrogen fixation studies in xeric shrubs. However, it assumes that both species use the same ...
The elusive quantification of nitrogen fixation in xeric shrubs: The case of Adesmia volckmanni, a Patagonian leguminous shrub
(Academic Press Ltd - Elsevier Science Ltd, 2014-12)
The comparison of 15N natural abundance (δ15N) between fixing and non-fixing reference species, is the most feasible method for nitrogen fixation studies in xeric shrubs. However, it assumes that both species use the same ...
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 ...
