Differential DNA methylation and gene expression during development of reproductive and vegetative organs in Ilex species
(Springer, 2021-03)Differential epigenetic (DNA cytosine methylation) and gene expression patterns were investigated in reproductive and vegetative organs from Ilex paraguariensis and I. dumosa, at distinct developmental stages. We aimed at ... -
Accounting for competition in multi-environment tree genetic evaluations: a case study with hybrid pines
(Springer, 2021-01)A novel multi-environment competition individual-tree mixed model resulted in better fit, and greater individual narrow- and broad-sense heritabilities than the model without competition, notably for traits showing ... -
Daily, seasonal, and interannual variability of airborne pollen of Araucaria angustifolia growing in the subtropical area of Argentina
(Springer, 2020-02)Araucaria angustifolia is an anemophilous conifer native to Southern America threatened with extinction, with a noticeable decrease in its distribution area and seed production. To better understand the reproductive dynamics, ... -
Native tree regeneration in native tree plantations: understanding the contribution of Araucaria angustifolia to biodiversity conservation in the threatened Atlantic Forest in Argentina
(Wiley, 2020)Deforestation is a global process that has strongly affected the Atlantic Forest in South America, which has been recognised as a threatened biodiversity hotspot. An important proportion of deforested areas were converted ... -
Morphological and physiological plasticity in seedlings of Araucaria angustifolia and Cabralea canjerana is related to plant establishment performance in the rainforest
(Elsevier, 2020)High phenotypic plasticity is an important characteristic that should have a tree species that is going to be used to restore degraded rainforests, as those are stressful and changing environments. Quantifying phenotypic ... -
Morphometry of tracheids of Pinus taeda L. from a pruning test in NE Argentina
(Centro de Pesquisas Florestais da Faculdade de Florestas da Universidade Federal do Paraná, 2019-09)The northeast region of Argentina is characterized by fast-growing forest plantations, Pinus taeda among them.
