Multiscale spatial planning to maintain forest connectivity in the Argentine Chaco in the face of deforestation
(Resilience Alliance, 2018)Agricultural expansion threatens biodiversity due to habitat loss and fragmentation. In the Gran Chaco, a global deforestation hotspot, rampant cropland and pasture expansion raise concerns about the sustainability of these ... -
Multivariate mapping of soil with structural equation modelling
(2017-09)In a previous study we introduced structural equation modelling (SEM) for digital soil mapping in the Argentine Pampas. An attractive property of SEM is that it incorporates pedological knowledge explicitly through a ... -
Munroa argentina, a grass of the South American transtion zone, survived the Andean uplift, aridification and glaciations of the quaternary
(2015-06-25)The South American Transition Zone (SATZ) is a biogeographic area in which not only orogeny (Andes uplift) and climate events (aridification) since the mid-Miocene, but also Quaternary glaciation cycles had an important ... -
Nanostructured voltammetric sensor for ultra-trace anabolic drug determination in food safety field
(2013-11)A sensitive electrochemical sensor for clenbuterol (CL) determination in bovine urine samples was designed. This drug was originally developed for the treatment of respiratory pathologies. However, in the livestock industry, ... -
National-scale soybean mapping and area estimation in the United States using medium resolution satellite imagery and field survey
(2017)Reliable and timely information on agricultural production is essential for ensuring world food security. Freely available medium-resolution satellite data (e.g. Landsat, Sentinel) offer the possibility of improved global ... -
Natural forests loss and tree plantations: Large - scale tree cover loss differentation in a threatened dioviversity hotspot.
(IOP Publishing, 2020-12-14)Distinguishing between natural forests from exotic tree plantations is essential to get an accurate picture of the world’s state of forests. Most exotic tree plantations support lower levels of biodiversity and have less ... -
La naturaleza, una brillante ingeniera en desarrollos tecnológicos
(Asociación Argentina para el Progreso de las Ciencias, 2022)La naturaleza nos brinda un sinfín de ideas para el desarrollo de nuevas tecnologías más sustentables y ecológicamente superiores. En el presente trabajo se describen, brevemente y con algunos ejemplos, los materiales ... -
Neurobehavioral evaluation and phytochemical characterization of a series of argentine valerian species
(Elsevier, 2020-12)Folkloric or galenic preparations of valerian roots and rhizomes have been used as sedatives/anxiolytics and sleep inducers since ancient times. “Valerianas” are plants that naturally grow in our region. Although some of ... -
New records of Petunia (Solanaceae) for theArgentinean flora
(Instituto de Botánica Darwinion, 2005)Petunia interior and P. guarapuavensis are reported for the first time for the Argentinean flora, andtheir geographical distributions are updated. -
New data on the endangered Chacoan peccary (Catagonus wagneri) link the core distribution with its recently discovered southern population
(De Gruyter, 2018-09)The endangered Chacoan peccary (Catagonus wagneri Rusconi, 1930) has been recorded in western Paraguay, southeastern Bolivia and northern Argentina, reaching the north of Santiago del Estero province. Recently, however, ... -
New host record of Sclerotium rolfsii causing crown and root rot on Pseudogynoxis benthamii
(Instituto de Biología, Universidad Nacional Autónoma de México, 2018-03-13)Symptoms of a wilt disease were observed on 10 of 40 plants of Pseudogynoxis benthamii grown in Buenos Aires, Argentina, in March 2016. The aim of this study was to identify the causal agent of the disease. Five phenotypically ... -
New insights into antibacterial and antioxidant activities of rosemary essential oils and their main components
(2013-05)Rosemary plants growing in Argentina were studied to evaluate any relationship between the chemical composition of their essential oils and the free radical scavenging capacity. The antibacterial activity against human ... -
New insights into the chemical biodiversity of Minthostachys mollis in Argentina
(Elsevier, 2014-12)Variations in the chemical composition of the essential oils of Minthostachys mollis Griseb. (Lamiaceae) collected in their natural habitat in Argentina were determined using GC-FID-MS analysis. Seventy five samples collected ... -
A new polyploid species of Mecardonia (Gratioleae, Plantaginaceae) from South America
(2017-04)Mecardonia reneeae, a new species from northeastern Argentina, is described and illustrated. This taxon has certain resemblance to M. procumbens var. flagellaris, but can be easily distinguished by the combination of life ... -
