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 ... -
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 ... -
From Kyoto to Paris: Measuring renewable energy policy regimes in Argentina, Brazil, Canada, Mexico and the United States
(2019-04)There are numerous strategies to lower greenhouse gas (GHG) emissions or to mitigate global climate change. One of them is to promote polices for developing renewable energy sources. There has been a growth in such policies ... -
From lignocellulosic metagenomes to lignocellulolytic genes : trends, challenges and future prospects
(2016)Lignocellulose is the most abundant biomass on Earth with immense potential to act as a primary resource for the production of a range of compounds currently obtained from fossil fuel sources. However, lignocellulosic ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
(Wiley, 2015-08)1. The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ... -
Frutos nativos conservados en forma de pellets para alimentación de rumiantes menores
(Universidad Nacional de La Matanza; INTA, 2023-10)El uso de frutos nativos como suplemento en rumiantes es una práctica difundida, pero existen inconvenientes en el almacenamiento, por la infestación con insectos (principal y comúnmente llamados brúquidos, a diferentes ... -
Functional analysis of Spodoptera frugiperda nucleopolyhedrovirus late expression factors in Sf9 cells
(2013-02)We used transient expression assays to assess the function of the baculovirus Spodoptera frugiperda M nucleopolyhedrovirus (SfMNPV) homologs of Autographa californica MNPV (AcMNPV) factors involved in late gene expression ... -
Functional and biochemical properties of Mal de Río Cuarto virus (Fijivirus, Reoviridae) P9-1 viroplasm protein show further similarities to animal reovirus counterparts
(Elsevier, 2010-09)Mal de Río Cuarto virus (MRCV) is a plant virus of the genus Fijivirus within the family Reoviridae that infects several monocotyledonous species and is transmitted by planthoppers in a persistent and propagative manner. ... -
Functional characterization and intracellular localization of a Lotus tenuis NHX antiporter
(Springer, 2021-05)Lotus tenuis is a perennial forage legume widely scattered in the flooding Pampa region of Argentina. Even when it is considered a salt-tolerant species, the molecular basis underlying this trait still remains unknown. ... -
Functional syndromes as indicators of ecosystem change in temperate grasslands
(Elsevier, 2018-09-24)The lack of an organizing conceptual framework to address ecosystem changes reduces our capacity to distinguish biophysical from direct human impacts on grassland dynamics. This is particularly important for subhumid ... -
Fungal screening and aflatoxin production by Aspergillus section Flavi isolated from pre-harvest maize ears grown in two Argentine regions
(Elsevier, 2017-02)Aflatoxin contamination in maize kernels grown in central Argentina has increased since 2008. Pre-harvest maize ear samples were collected during two growing seasons to determine prevalent fungal genera as well as aflatoxin ... -
Fungicide efficacy of nanocrystal-based formulations against peanut smut
(Elsevier, 2021-03)Nanocrystal-based formulations were investigated as a novel technology to increase the fungicide efficacies of azoxystrobin (AZY), cyproconazole (CYP), and their combination (AZY + CYP) against peanut smut caused by ... -
Fungicide resistance in Cercospora species causing cercospora leaf blight and purple seed stain of soybean in Argentina
(Wiley, 2020-12)Cercospora species cause cercospora leaf blight (CLB) and purple seed stain (PSS) on soybean. Because there are few resistant soybean varieties available, CLB/PSS management relies heavily upon fungicide applications. ... -
