Agroecología: algo más que producir sin agrotóxicos
(Ediciones INTA, 2018-12)
Muchas veces se menciona a la agroecología como una forma de producir alimentos sin utilizar agroquímicos, sin embargo, es mucho más que eso. La noción de agroecología implica considerarla como una disciplina científica, ...
Effect of scale on trait predictors of species responses to agriculture
(WileyConservation Biology, 2017)
Self‐regeneration of hairy vetch (Vicia villosa Roth) as affected by seedling density and soil tillage method in a semi‐arid agroecosystem
(2017-09)
Vicia villosa Roth is a forage legume with the capability for biological N fixation and natural reseeding, which could contribute to sustainability in semi‐arid regions. This study aimed to determine (i) the relationship ...
Vicia villosa ssp. villosa Roth field emergence model in a semiarid agroecosystem
(2018-03)
Hairy vetch (Vicia villosa Roth) is a winter annual legume cultivated for pasture and hay with the capability for natural reseeding. Vicia villosa increases N concentrations in the soil, thus contributing to the sustainability ...
Small mammal responses to farming practices in central Argentinian agroecosystems: the use of hierarchical occupancy models
(Ecological Society of Australia, 2018-08)
Organic farming is more environmentally friendly than conventional agriculture, promoting greater
levels of habitat heterogeneity. Field borders could be more suitable for biodiversity in agricultural anthromes.

Pesticides detected in surface and groundwater from agroecosystems in the Pampas region of Argentina: occurrence and ecological risk assessment
(Springer, 2021-10-02)
The objective of this study was to evaluate the occurrence of pesticides in surface and groundwater of agricultural areas of the Pampas region of Argentina and to develop an ecological risk assessment (ERA) of pesticides ...
Enhancing agroecosystem productivity with woody perennials in semi-arid West Africa. A meta-analysis
(Springer Verlag, 2018-12)
Soil degradation in semi-arid West Africa can be reversed through an intensified application of organic matter, especially on coarse soils. Woody perennials have been promoted in the region to secure organic matter sources ...
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
(2018-03)
Brassica rapa L. is an annual Brassicaceae species cultivated for oil and food production, whose wild form is a weed of crops worldwide. In temperate regions of South America and especially in the Argentine Pampas region, ...
Evaluation of the toxicity of the sediments from an agroecosystem to two native species, Hyalella curvispina (CRUSTACEA: AMPHIPODA) and Boana pulchella (AMPHIBIA: ANURA), as potential environmental indicators
(Elsevier Science, 2018-10)
In a study area chosen outside the city of La Plata (Buenos Aires, Argentina), two zones were selected having different types and magnitudes of agrarian activity: one represented mainly by grasslands with a low degree of ...
Extracting DNA of nematodes communities from Argentine Pampas agricultural soils
(2015)
We examined four strategies (Tris/EDTA, sodium dodecyl sulfate, Chelex 100 resin and
cetyltrimethylammonium bromide -CTAB-) for extracting nucleic acid (DNA) from communities of
nematodes. Nematodes were isolated from ...
