Impacts of population structure and analytical models in genome-wide association studies of complex traits in forest trees: a case study in Eucalyptus globulus
(Plos One, 2013-11-25)The promise of association genetics to identify genes or genomic regions controlling complex traits has generated a flurry of interest. Such phenotype-genotype associations could be useful to accelerate tree breeding cycles, ... -
Improving accuracy of breeding values by incorporating genomic information in spatial - competition mixed models
(2017-10)Climate change and the increasing demand for sustainable energy resources require urgent strategies to increase the accuracy of selection in tree breeding (associated with higher gain). We investigated the combined pedigree ... -
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 ... -
Improving lodgepole pine genomic evaluation using spatial correlation structure and SNP selection with single-step GBLUP
(Springer Nature, 2022-02-18)Modeling environmental spatial heterogeneity can improve the efficiency of forest tree genomic evaluation. Furthermore, genotyping costs can be lowered by reducing the number of markers needed. We investigated the impact ... -
Increasing reports in Mimosa (Mimosoideae, Leguminosae) for the Brazilian Flora
(Sociedad Argentina de Botánica, 2015-06)Five species of Mimosa for the Brazilian Flora are reported: M. strigillosa, M. leimonias, M. petraea, M. oligophylla, and M. barnebiana. The three first ones are registered from Mato Grosso do Sul, while the remainder are ... -
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 ... -
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 ... -
Integrating genomic information and productivity and climate-adaptability traits into a regional white spruce breeding program
(Plos ONE, 2022-03)Tree improvement programs often focus on improving productivity-related traits; however, under present climate change scenarios, climate change-related (adaptive) traits should also be incorporated into such programs. ... -
Intraspecific variation in essencial oil composition of A.N. the medicinal plant Lippia integrifolia (verbenaceae), evidence for five chemotypes
(2016-02)The aerial parts of Lippia integrifolia (incayuyo) are widely used in northwestern and central Argentina for their medicinal and aromatic properties. The essential oil composition of thirty-one wild populations of L. ... -
Karyotype studies in Mimosa (Mimosoideae, Leguminosae) from Southern South America and ecological and taxonomic relationships
(Taylor & Francis, 2011)In this work we studied the chromosome number and karyotype formula of seven species of Mimosa L. (Mimosoideae, Leguminosae). The chromosome number 2n = 2x = 26 for M. detinens Benth., M. hex- andra M. Micheli, M. ostenii ... -
Land use changes and bird diversity in subtropical forests: urban development as the underlying factor
(Springer, 2022-12-15)The Serrano Chaco forest is the least extended Gran Chaco forest type with a long his tory of human disturbances, such as ranching, urbanization, fires, an exotic tree species expansion, which have altered natural vegetation ... -
Leaf venation pattern to recognize austral South American medicinal species of “cow's hoof” (Bauhinia L., Fabaceae)
(Elsevier, 2017-04)The leaves extracts of some species of Bauhinia L. s.l. are consumed to treat diabetes, inflammation, pains and several disorders in traditional medicine in austral South America. Despite its wide use and commercialization, ... -
Leaflet trichome micromorphology in the Dolentes-Brevipedes taxonomic complex (Mimosa L., Mimosoideae)
(Tubitak Scientific & Technical Research Council, Turquía, 2016)We studied leaflets of 18 taxa of the genus Mimosa, specifically the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape, and density of trichomes. Within the nonglandular trichomes we described ... -
Lectotipificaciones en Mimosa (Leguminosae) del sur de Sudamérica
(Sociedad Argentina de Botánica, 2018)Se procedió a realizar la lectotipificación de tres especímenes del género Mimosa L. que crecen en Argentina: M. obstrigosa Burkart, M. tandilensis Speg. y M. callosa var. longiracemosa Burkart. Se describe el procedimiento ... -
