La fotooxidación en la semilla de sauce y sus consecuencias en la imbibición y formación de la plántula
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2012-06)A diferencia de lo que ocurre en una semilla ortodoxa típica, los tejidos embrionarios de las semillas de sauce (Salix nigra L.) presentan cloroplastos que no desdiferencian durante la maduración del secado, por lo que ... -
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
(Wiley, 2018-10-31)The fast expansion of human population around La Paz, Bolivia (3,200–4,100 m.a.s.l.) triggered new suburban settlements in nearby areas in valleys and mountain feet. The white mesquite, Prosopis alba Griseb. (Leguminosae), ... -
Genetic parameters for growth, stem straightness, and branch quality for Pinus elliottii var. elliottii × Pinus caribaea var. hondurensis F1 Hybrid in Argentina
(Oxford University Press, 2018-11)Genetic parameters for growth, stem straightness, and branch quality were estimated in five progeny trials of Pinus elliottii var. elliottii (PEE) × Pinus caribaea var. hondurensis (PCH) F1 hybrid measured at ages three, ... -
Genetic structure in cultivated quinoa (Chenopodium quinoa Willd.), a reflection of landscape structure in Northwest Argentina
(Springer, 2012-08)Quinoa (Chenopodium quinoa Willd.), one of the main crops domesticated in the Andean highlands 1,000 of years ago, played an important role as a protein source. 35 germplasm accessions collected along the Northwest Argentina ... -
Genetic studies of various Prosopis species (Leguminosae, Section Algarobia) co- occurring in oases of the Atacama Desert (northern Chile)
(Wiley, 2021-03-01)In the Atacama Desert from northern Chile (19– 24°S), Prosopis (Leguminosae) individuals are restricted to oases that are unevenly distributed and isolated from each other by large stretches of barren landscape constituting ... -
Genetic variability of Araucaria angustifolia in the Argentinean Parana Forest and implications for management and conservation
(2018-08)The main forces shaping genetic variability of woody species in fragmented forest are the geographical distribution and demographic history of populations. We conducted molecular analyses to evaluate how these factors have ... -
Genomic evaluation for breeding and genetic management in Cordia africana, a multipurpose tropical tree species
(BMC, 2024-01-02)Planting tested forest reproductive material is crucial to ensure the increased resilience of intensively managed productive stands for timber and wood product markets under climate change scenarios. Single-step Genomic ... -
Genomic selection in Canadian spruces
(Springer, 2020-01-01)The genetic gain of spruce (Picea spp.) breeding programs is impeded by long recurrent selection cycles stemming from biological constraints such as late expression of traits, weak juvenile mature correlations, and late ... -
Genomic-based multiple-trait evaluation in Eucalyptus grandis using dominant DArT markers
(2018-06)We investigated the impact of combining the pedigree- and genomic-based relationship matrices in a multiple-trait individual-tree mixed model (a.k.a., multiple-trait combined approach) on the estimates of heritability and ... -
Glossy privet (Ligustrum lucidum) invasion decreases Chaco Serrano forest bird diversity but favors its seed dispersers
(Springer, 2020-11)Glossy privet (Ligustrum lucidum) is an aggressive invasive plant that replaces native forests and forms dense stands without understory in central Argentina. However, the consequences of these changes in terms of vegetation ... -
