Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
(2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Effect of the Hope FT-B1 Allele on wheat heading time and yield components
(2014-09)Precise regulation of flowering time is critical for plant reproductive success and, in cereals, to maximize grain yields. Seasonal cues including temperature and day length are integrated to regulate the timing of flowering. ... -
Effects of past and future land conversions on forest connectivity in the Argentine Chaco
(Springer, 2015-05)Context: Land-use change is the main driver of habitat loss and fragmentation worldwide. The rate of dry forest loss in the South American Chaco is among the highest in the world, mainly due to the expansion of soybean ... -
Effects of the neonicotinoid insecticides Thiamethoxam and imidacloprid on metamorphosis of the toad rhinella arenarum at environmentally-relevant concentrations

Efficient genomics-based ‘end-to-end’ selective tree breeding framework
(Springer Nature, 2024-01-03)Since their initiation in the 1950s, worldwide selective tree breeding programs followed the recurrent selection scheme of repeated cycles of selection, breeding (mating), and testing phases and essentially remained unchanged ... -
Essential oil chemotypes of Aloysia citrodora (Verbenaceae) in Northwestern Argentina
(Elsevier, 2017-10)Chemical biodiversity of essential oils of natural populations of Aloysia citrodora Palau (“lemon verbena”, “cedrón”) in Northwestern Argentina was assessed by collecting in the same sites through different years. A total ... -
Estudio farmacobotánico de Ipomoea purpurea (L.) Roth (Convolvulaceae)
(Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2018-01-04)Ipomoea purpurea (L.) Roth (Convolvulaceae) es una especie que se desarrolla en las zonas tropicales de ambos hemisferios. Por el atractivo de sus flores pertenece al grupo conocido como “Common morning glory”, especies ... -
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, ... -
Fading opportunities for mitigating agriculture-environment trade-offs in a south American deforestation hotspot
(Elsevier, 2021-10)Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are ... -
Fire Regime, Climate, and Vegetation in the Sierras de Córdoba, Argentina
(2015)Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012. However, little is known about the spatial and temporal patterns of fires and their ... -
First test for eradication of beavers (Castor canadensis) in Tierra del Fuego, Argentina
(Springer, 2020-08)The North American beaver (Castor canadensis) was introduced in 1946 from Canada to Isla Grande de Tierra del Fuego to develop a fur industry. Their expansion to most of the habitats of Tierra del Fuego and their presence ... -
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 ... -
Future Land-Use Changes and the Potential for Novelty in Ecosystems of the United States
(2015-12)Rapid global changes due to changing land use, climate, and non-native species are altering environmental conditions, resulting in more novel communities with unprecedented species combinations. Understanding how future ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
(2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
Genetic diversity and differentiation among Prosopis alba (Leguminosae) populations from dry valleys of Bolivia with different levels of human disturbance and altitude
