LAMP technology: Rapid identification of Brucella and Mycobacterium avium subsp. paratuberculosis
(Sociedade Brasileira de Microbiologia, 2015-06)In this study, we developed new sets of primers to detect Brucella spp. and M. avium subsp. paratuberculosis (MAP) through isothermal amplification. We selected a previously well-characterized target gene, bscp31, specific ... -
Land cover, plant residue and soil microbes as drivers of soil functioning in temperate agricultural lands. A microcosm study
(Elsevier, 2024-01-01)Feedbacks between plants and soil microbes are critical for ecosystem regulation and restoration. Soil microbial diversity is largely dependent on plant diversity, yet these relationships have received little attention at ... -
Land degradation assessment in the Argentinean Puna: Comparing expert knowledge with satellite-derived information
(Elsevier, 2018-11)The Puna region, located in NW Argentina, is a dry highland with many endemic species and significant traditional cultural heritage. The Puna was a pilot region for the Land Degradation Assessment in Drylands project ... -
Land sharing in South Patagonia: Conservation of above-ground beetle diversity in forests and non-forest ecosystems
(Elsevier, 2019-11)Land-sharing strategies, as variable retention silvicultural proposals, are useful to mitigate harmful effects of economic activities on forest biodiversity; benefits have been reported worldwide for several organisms. ... -
Land tenancy, soybean, actors and transformations in the pampas: A district balance
(2015-06)In Argentina, the recent expansion of agriculture has turned into an extreme process almost completely dominated by soybean. The magnitude and speed of soybean expansion are believed to be the main drivers behind social, ... -

Land use intensity and cropping sequence effects on aggregate stability and C storage in a Vertisol and a Mollisol
(2013)The relevant change in land use duemainly to the rapid expansion of soybean cropping towards areas traditionally occupied for livestock purposes or with native grasslands of South America may have negative consequences on ... -
Land-use change affects soil hydro-physical properties in Mollisols of semiarid Central Argentina
(Elsevier, 2021-06-01)The objective of the present study was to describe the relationships between soil physical properties and to identify variables that determine the pore system and hydrological functions which are specifically important in ... -
Land-use change affects the diversity and functionality of soil bacterial communities in semi-arid Chaco region, Argentina
(Elsevier, 2022-04)The semi-arid Chaco ecoregion has been heavily affected by the conversion of pastures to cropland. Our knowledge about the impact of land use change on soil microbial community diversity and functions in this region is ... -
Landholders’ perceptions on legal reserves and agricultural intensification: Diversity and implications for forest conservation in the eastern Brazilian Amazon
(Elsevier, 2021)Forest conservation on privately owned lands is a cornerstone of the Brazilian environmental policy framework. Brazilian legislation requires that all farms in the country maintain and protect forest areas known as Legal ... -
Landscape configuration modulates the presence of leaf-cutting ants in eucalypt plantations
