The chromosome region including the earliness per se locus Eps-Am1 affects the duration of early developmental phases and spikelet number in diploid wheat
(Society for Experimental Biology, 2008-10)Earliness per se genes are those that regulate flowering time independently of vernalization and photoperiod, and are important for the fine tuning of flowering time and for the wide adaptation of wheat to different ... -
Frog somatic indices: Importance of considering allometric scaling, relation with body condition and seasonal variation in the frog Leptodactylus latrans
(Elsevier, 2020)Snout-vent length (SVL) and liver, gonad, fat bodies and carcass weight data from 661 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best ... -
Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco
(2020-03-17)Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of ... -
Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus Latrans
(2020-01-08)Body weight and snout-vent length (SVL) data of 3006 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best approach for expressing body condition ... -
Increment coring induced traumatic resin ducts in white spruce but not in lodgepole pine
(2020-01-30)Injury from sampling increment cores may induce defense responses in trees, which may vary between species and reflect differing defense allocation strategies against attack by insects and pathogens. We recorded presence ... -
Review of situation of Hedeoma multiflora Benth (Peperina de las lomas): an aromatic - medicinal Argentine species at risk
(Universidad de Santiago de Chile, 2020-01-30)Aromatic and medicinal plants (AMPs) have great potential for the synthesis of secondary metabolites, which are used by the pharmaceutical and food industry. In addition, they are part of ancestral medicine and the livelihood ... -
Biomarker and hematological fieldwork with amphibians: is it necessary to sample all night?
(Springer, 2020-03)In the context of the global amphibian crisis, biomonitoring constitutes a valuable assessment tool to provide critical up to date information on the status and health of amphibians worldwide. The aim of the current study ... -
Exposure of Nonbreeding Migratory Shorebirds to Cholinesterase Inhibiting Contaminants in the Western Hemisphere
(Oxford Academic Press, 2010-02)Migratory shorebirds frequently forage and roost in agricultural habitats, where they may be exposed to cholinesterase-inhibiting pesticides. Exposure to organophosphorus and carbamate compounds, common anti-cholinesterases, ... -
Primer Informe del Virus de la Papa Y en Calibrachoa Ornamental en Argentina
(2019-04-24)The identification of the calibrachoa-infecting PVY strain is vital for resistant-cultivar selection, and therefore it should be addressed in future studies. To our knowledge, this is the first report of PVY as a pathogen ... -
A new species of Petunia (Solanaceae) from Corrientes, Argentina = Una nueva especie de Petunia (Solanaceae) de Corrientes, Argentina
(2019-08-21)Describimos e ilustramos una nueva especie de Petunia , P. correntina , del suroeste de Corrientes, Argentina, en el sur de América del Sur. La especie tiene corola en forma de embudo con tubo de color verde blanquecino y ... -
Bauhinia affinis (Fabaceae) : una nueva cita para la flora argentina
(Instituto de Botánica Darwinion, 1996)Bauhinia affinis Vogel is reported for the first time in the NE extreme of Argentina. The number of species of the genus recorded for the country is increased to 7. The species is described and illustrated indicating ist ... -
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. -
Biodiversity loss in deforestation frontiers: Linking occupancy modelling and physiological stress indicators to understand local extinctions
(Elsevier, 2019-05-27)Tropical deforestation is a main driver of the global biodiversity crisis. Impact assessments typically focus on species' presence, which means impacts are detected when local extinctions have occurred – and thus when it ... -
Quantitative genetic parameters for growth and wood properties in Eucalyptus “urograndis” hybrid using near-infrared phenotyping and genome-wide SNP-based relationships
(2019-06-24)A thorough understanding of the heritability, genetic correlations and additive and non-additive variance components of tree growth and wood properties is a requisite for effective tree breeding. This knowledge is essential ... -
Diversity and conservation of legumes in the Gran Chaco and biogeograpical inferences
(Plos ONE, 2019-08-14)The Gran Chaco is a wide ecologic-geographic region comprising northern Argentina, western Paraguay, southern Bolivia and the southwestern extreme of Brazil. This region exhibits extreme temperatures, annually regular ... -
Shinyssd v1.0: Species sensitivity distributions for ecotoxicological risk assessment
(2019-05-29)Living organisms have different sensitivities to toxicants. This variability can be represented by constructing a species sensitivity distribution(SSD) curve, where by the toxicity of a substance to a group of species is ... -
Identification of smut resistance in wild arachis species and its introgression into peanut elite lines
(Crop Science Society of America, 2019-05-16)Peanut smut caused by Thecaphora frezii Carranza & Lindquist has been an issue for farmers and the peanut industry (Arachis hypogaea L.) in Argentina since the mid-1990s. This disease causes pod malformation due to hypertrophy ... -
Improving genomic prediction of growth and wood traits in Eucalyptus using phenotypes from non-genotyped trees by single-step GBLUP
(Elsevier, 2019-03-28)Genomic Best Linear Unbiased Prediction (GBLUP) in tree breeding typically only uses information from genotyped trees. However, information from phenotyped but non-genotyped trees can also be highly valuable. The single-step ... -
