Decomposition and nutrient dynamic of leaf litter and roots from palatable and unpalatable grasses in a semi-arid grassland
Since below-ground production represents the major input of new soil organic matter in the system, the N and P dynamics of roots suggest a low capacity to immobilize nutrients in both palatable and unpalatable grasses. Expand
Litter quality and nutrient cycling affected by grazing‐induced species replacements along a precipitation gradient
Results indicate that grazing may significantly alter nutrient cycling by affecting litter quality through changes in species composition, and these effects seem to be larger when species replacements induced by grazing either involve functional groups, as it was the case in the wettest site, or change root to shoot ratios.

How to know the fungi: combining field inventories and DNA-barcoding to document fungal diversity.
The fungi kingdom is among the most diverse eukaryotic lineages on Earth with estimates of several million extant species (O’Brien et al., 2005; Blackwell, 2011; Taylor et al., 2014). Fungi playExpand
Decomposition of and nutrient dynamics in leaf litter and roots of Poa ligularis and Stipa gyneriodes
Both species showed similar pattern of P and N dynamics in the leaf litter and roots, but net mineralization was higher in Poa ligularis than in S. gynerioides. Expand
Competitive interactions between palatable and unpalatable grasses native to a temperate semi-arid grassland of Argentina
The results support the assumption, on which most interpretations of floristic changes induced by grazing are based, that the competitive ability of palatable grasses is higher than the one of unpalatablegrasses in the absence of grazing. Expand
Variations in chemical composition associated with tissue aging in palatable and unpalatable grasses native to central Argentina
The results suggest that the relatively high nutritive value of the unpalatable species at early plant growth stages following burning may create a window of time, in which it may be more readily grazed by livestock. Expand
Nutrient resorption from senescing leaves in two Stipa species native to central Argentina
Compared with two congener grasses that successfully occupy uplands of relatively low fertility or lowlands of relatively high fertility in natural grasslands of central Argentina, Stipa gynerioides had a higher N and P resorption proficiency than S. brachychaeta, and was associated with relatively low leaf-litter decomposition and nutrient release rates found in a previous study.

Long-term forest management research in South Patagonia - Argentina: lessons from the past, challenges from the present.
Argentina ha basado su economia en la agricultura y el ganado, donde el bosque ha sido visto como un obstaculo para el desarrollo. La cosecha forestal en Patagonia Sur ha sido una actividad basada enExpand
Social demands related to native forest ecosystems are based on an efficient management, with a balance between conservation and timber production. This paper describes the industry adaptation to aExpand
Soil nitrogen availability under grasses of different palatability in a temperate semi-arid rangeland of central Argentina
The results suggest that the replacement of palatable grasses by unpalatablegrasses in the temperate semi-arid rangelands of central Argentina may imply a reduction in the rate of nutrient cycling. Expand
