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 ...

Individual plant and population biomass of dominant shrubs in Patagonian grazed fieldsBiomasa individual y poblacional de arbustos dominantes en estepas patagónicas pastoreadas
(Asociación Argentina de Ecología, 2010-12)
Estimating aboveground biomass of vegetation is essential for population, community and ecosystem studies. In systems dominated or co-dominated by woody species, biomass estimation is difficult, and rapid and non-destructive ...
Seed compositional studies of some species of Papilionoideae (Leguminosae) native to Argentina
(John Wiley & Sons Ltd, 2002-12)
Seeds of 17 wild leguminous species belonging to the Papilionoideae subfamily were analysed for their proximate, fatty acid and sterol compositions. Centrosema virginianum, Tipuana tipu, Adesmia volckmanni and some species ...
Resource partitioning and interactions enable coexistence in a grass-shrub steppe
(Academic Press Ltd - Elsevier Science Ltd, 2010-10)
We revisited a growth-form removal experiment after 12 years with the aim to compare the long-term population responses of three shrub species. Specifically, we were interested to know if the resource partitioning and plant ...
