(2017-05)The occurrence of the exotic “granulate ambrosia beetle” Xylosandrus crassiusculus (Motschulsky) in Argentina and Uruguay is reported for the first time, documenting expansion in South America. Morphological characters are ... -
Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-07)Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This species comprises two varieties, which are distinguished by the indumentum. However, this character is ... -
Multi-season regional analysis of multi-species occupancy : implications for bird conservation in agricultural lands in East-Central Argentina
(2015-07-18)Rapid expansion and intensification of agriculture create challenges for the conservation of biodiversity and associated ecosystem services. In Argentina, the total row crop planted area has increased in recent decades ... -
Multiple Level Effects of Imazethapyr on Leptodactylus latinasus (Anura) Adult Frogs
(Springer, 2021-08)Imazethapyr is an herbicide that is used in a variety of crops worldwide, including soybean and corn. The aim of the present study was to evaluate the biomarkers responses of adult Leptodactylus latinasus exposed to the ... -
Multiple-trait analyses improved the accurary of genomic prediction and the power of genome-wide association of productivity and climate change-adaptive traits in lodgepole pine
(BMC, 2022-07-23)Genomic prediction (GP) and genome-wide association (GWA) analyses are currently being employed to accelerate breeding cycles and to identify alleles or genomic regions of complex traits in forest trees species. Here, 1490 ... -

(BMC, 2022-07-23)Genomic prediction (GP) and genome-wide association (GWA) analyses are currently being employed to accelerate breeding cycles and to identify alleles or genomic regions of complex traits in forest trees species. Here, 1490 ... -
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 ... -
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, ... -
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 ... -
