Technological Organization in Hunting/Scavenging and Butchering Sites of Megamammals in the Pampa Grasslands (Argentina)
(Taylor & Francis, 2015-10)
The objectives of this research were to evaluate different modes of lithic acquisition, use, and disposal at three single-component open-air sites associated with the hunting/scavenging and butchering of megamammal species, ...
Effects of Urochloa humidicola on Plant Diversity in Native Grasslands in a Neotropical Wetland
(Springer, 2015-10-01)
Studies on species invasion in wetlands are fundamental to understanding the consequences of the introduction of exotic plants, which are often utilized in grasslands. The loss of native plant diversity is of increasing ...
Distribution and effects of tree leaf litter on vegetation composition and biomass in a forest-grassland ecotone
(Oxford University Press, 2014-06)
Aims: After abandonment of grasslands, secondary succession leads to the invasion by woody species. This process begins with the accumulation of tree litter in the forest–grassland ecotone. Our objectives were to determine ...
Livestock grazing affects microclimate conditions for decomposition process through changes in vegetation structure in mountain grasslands
(Gauthier-Villars/Editions Elsevier, 2018-08)
It is often assumed that a change in litter quality is the main driver of alterations in the decomposition process when grazers modify vegetation structure. Soil microclimate is also modified, but this driver of decomposition ...
Disentangling grazing and light controls on algal communities in grassland and afforested streams
(Springer Tokyo, 2019-01-30)
Our aim was to analyze the combined effect of grazing and light on composition, structure, functional diversity (FD) and succession of algal communities in two headwater streams (grassland and pine afforested). We hypothesized ...
Overseeding legumes in natural grasslands: Impacts on root biomass and soil organic matter of commercial farms
(Elsevier, 2020-11)
Overseeding legumes in natural grasslands coupled with phosphorous fertilization are management practices oriented to increase forage production and quality, and to restore nutrient losses generated by livestock. Several ...
Linking plant strategies and ecosystem function: an assessment of the contribution of biodiversity to neotropical grassland productivity
(2015-11-03)
To understand the diversity of strategies of resource use at the species and community level of co-existing species in semi-natural grasslands, I used three differentapproaches: a) the comparison of above-ground net primary ...
Linking plant strategies and ecosystem function: an assessment of the contribution of biodiversity to neotropical grassland productivity
(2013-06-03)
To understand the diversity of strategies of resource use at the species and community level of co-existing species in semi-natural grasslands, I used three different approaches: a) the comparison of above-ground net primary ...
Presas del nuco (Asio flammeus) en un área de pastizal pampeano de ArgentinaPrey of the Short-eared Owl (Asio flammeus) in a Pampas grasslands area of Argentina
(Unión de Ornitólogos de Chile, 2014-08)
We describe the prey of the Short-eared Owl in a Pampas grassland area of Argentina on the basis of pellets occasionally collected (N = 10). We found a high proportion of small mammals within samples (80% by number and 97% ...
