Modeling extreme values for height distributions in Pinus pinaster, Pinus radiata and Eucalyptus globulus stands in northwestern Spain
(Italian Society of Silviculture and Forest Ecology (SISEF), 2015)Methods of estimating extreme height values can be used in forest modeling to improve fits to the marginal distribution of heights in the following bivariate diameter-height models: the SBB Johnson’s distribution, the ... -
EucaTool®, a cloud computing application for estimating the growth and production of Eucalyptus globulus Labill
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2015)Aim of study: To present the software utilities and explain how to use EucaTool®, a free cloud computing application developed to estimate the growth and production of seedling and clonal blue gum (Eucalyptus globulus ... -
Influence of blue stain on density and dimensional stability of Pinus radiata timber from northern Galicia (Spain)
(De Gruyter, 2015-01-31)The presence of blue-stain fungi considerably decreases the value of Pinus radiata timber, which is commercially important in Galicia (NW Spain). For this study, seven young pine trees growing in four different plantations ... -
Selección del tratamiento óptimo de aguas residuales para poblaciones del medio rural de Galicia
(Infoedita Comunicación profesional S.L., 2015-10)La depuración de aguas residuales en pequeños núcleos debe orientarse hacia alternativas diferentes a las que se suelen aplicar en poblaciones de mayor tamaño. En este sentido, la tecnología actual ofrece un amplio abanico ... -
La ordenación de las poblaciones de fauna cinegética para la práctica de la caza. El caso del TECOR Oleiros-Rioaveso (Villalba, Lugo)
(Biblioteca del Seminario Diocesano de Lugo, 2015-11)En este artículo se argumenta sobre la necesidad de los proyectos de ordenación de los recursos cinegéticos y se pone como ejemplo el caso del TECOR Oleiros-Rioaveso (Villalba, Lugo), en el que se hace una descripción ... -
Crecimiento y distribución de biomasa aérea en clones de castaño híbrido a edad temprana
(Sociedad Española de Ciencias Forestales, 2016)Se presentan los resultados de la medición en 228 ejemplares de castaños híbridos de 20 clones distintos en vivero, de edades comprendidas entre 4 y 7 años. Se realizaron muestreos destructivos para caracterizar las ... -
