Multiple-trait analyses improved the accurary of genomic prediction and the power of genome-wide association of productivity and climate change-adaptive traits in lodgepole pine
(BMC, 2022-07-23)Genomic prediction (GP) and genome-wide association (GWA) analyses are currently being employed to accelerate breeding cycles and to identify alleles or genomic regions of complex traits in forest trees species. Here, 1490 ... -
Natural grassland conversion to agriculture or pine plantations: Effects on soil methane uptake
(Wiley, 2024-01-30)Upland soils are the only known biological sink for methane (CH4) by methanotrophic bacteria consumption. This process is mainly limited by the diffusion processes related to the soil's physical characteristics, which can ... -
Performance of Pinus elliottii, Pinus caribaea, their F1, F2 and backcross hybrids and Pinus taeda to 10 years in the Mesopotamia region, Argentina
(Springer, 2013-03)Performances of Pinus taxa were studied to 10 years of age in two trials in each of Misiones and Entre Ríos provinces across the Mesopotamia region of Argentina. Taxa comprised 22 populations from sources in Argentina, ... -
Phenotypic variation of basic wood density in Pinus ponderosa plus trees = Variación fenotípica de la densidad básica de la madera de árboles plus de Pinus ponderosa
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)Phenotypic selection generally reduces the variability of both the selected trait and other associated characteristics. Some species show a negative strong relationship between growth traits and wood ... -
Pine plantations and invasion alter fuel structure and potential fire behavior in a patagonian forest-steppe ecotone
(2018-03-03)Planted and invading non-native plant species can alter fire regimes through changes in fuel loads and in the structure and continuity of fuels, potentially modifying the flammability of native plant communities. Such ... -
Potential impact of the leaf‐cutting ant Acromyrmex lobicornis on conifer plantations in northern Patagonia, Argentina
(Wiley, 2011-05)The economic losses associated with crop damage by invasive pests can be minimized by recognizing their potential impact before they spread into new areas or crops. We experimentally evaluated the preferences of the ... -
Producción de biomasa de Brachiaria (Brachiaria brizantha) cv. Marandú en dos sistemas silvopastoriles de pino (Pinus elliottii) en Corrientes, Argentina
(Universidad de Concepción, Chile, 2017-08)Los sistemas silvopastoriles comienzan a cobrar importancia en la región del noreste argentino (NEA), en particular en los bosques implantados a fines de la década de 1990 e inicios del año 2000. El objetivo del presente ... -
Production ecology and reverse growth dominance in an old-growth ponderosa pine forest
(Elsevier, 2020-01)The growth of a stand is the sum of the growth of individual trees. Growth of individual trees can be explained by the amount of resources captured and how efficiently those resources are used (production ecology). The ... -
Rendimiento en el aserrado para grados de calidad de las clases superiores en apariencia y remanufactura en taxones de pinos en el NE de Argentina
(Facultad de Ciencias Forestales, Universidad Nacional de Misiones (UNaM) y EEA Montecarlo, INTA, 2023-09-21)The quality of the sawn wood destined for moldings and remanufacturing, especially of the higher-value upper classes, play a fundamental role when its main destination is the foreign market. The objective of this work was ... -
Rendimiento en el aserrado por grados de calidad de Apariencia en taxones de pinos en el NE de Argentina
(Facultad de Ciencias Forestales, Universidad Nacional de Misiones (UNaM) y EEA Montecarlo, INTA, 2023-09-21)The quality of sawn wood plays a fundamental role when its main destination is for export. The objective of this work was to evaluate the yield of sawn timber classified according to the Appearance standard. Forty-two trees ... -
Rendimiento en el aserrado por grados de calidad para remanufactura en taxones de pinos en el NE de Argentina
(Facultad de Ciencias Forestales, Universidad Nacional de Misiones (UNaM) y EEA Montecarlo, INTA, 2023-09-21)The remanufacturing industry is a very attractive option to improve the competitiveness of sawmills. The objective of this work was to evaluate the sawn timber of 42 basal logs from trees of 7 different taxas, in Factory ... -
Rendimiento total en el aserrado de trozas basales de taxones de pinos del NE de Argentina
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03-27)Son numerosos los estudios realizados en coníferas a los fines de determinar los rendimientos totales o brutos de los rollizos, pudiendo señalarse, entre las especies de rápido crecimiento del género Pinus spp., los ... -
Resistencia en flexión del Pino Ponderosa de la Patagonia Norte, Argentina
(2019-11)En la zona andina de las Provincias de Neuquén, Chubut y Río Negro existen más de 100.000 ha implantadas de coníferas, la gran mayoría con pino ponderosa (Pinus ponderosa Dougl x Laws). No existe a la fecha una norma de ... -
Silvopastoral systems in Patagonia, Argentina
(CAB International, 2017)In the late 1800s, agricultural activities in the ‘Pampas’ region near Buenos Aires expanded rapidly, and as a result, livestock production (mainly sheep) was pushed into marginal areas such as Patagonia (Table 11.1). ... -
Soil erodibility and quality of volcanic soils as affected by pine plantations in degraded rangelands of NW Patagonia
(2016-08)NW Patagonia in Argentina has high potential for planting fast-growing exotic conifers, supported by its volcanic soils. Nonetheless, many aspects related to the effects of pine plantations on soil are still unknown. We ... -
