A Pinus pinaster Ait. progeny trial involving 46 open pollinated families was established at two locations in Portugal (Leiria and Escaroupim). Height, diameter, Pilodyn and stem characteristics (straightness, branch size and number of whorls) were assessed at age 5 and 12 and were used to estimate variance components, heritability, phenotypic and genetic correlations between traits. Estimates ...

Information on the dispersal ability of invertebrate species associated with woodland habitats is severely lacking. Therefore, a study was conducted examining the movement patterns of wood cricket (Nemobius sylvestris) (Orthoptera: Gryllidae) on the Isle of Wight, UK. Juvenile (i.e. nymphs) and adult wood crickets were released and observed over time within different ground surface substrates. ...

Wood structure and function of juvenile wood from 18 conifer species from four conifer families (Araucariaceae, Cupressaceae, Pinaceae and Podocarpaceae) were examined for a trade-off between wood reinforcement and hydraulic efficiency. Wood density and tracheid 'thickness-to-span' ratio were used as anatomical proxies for mechanical properties. The thickness:span represented the ratio of trach...

—Some species exhibit sex-specific color differences (sexual dichromatism) that are considered important for reproduction. The developmental timing of sexual dichromatism is largely unknown, particularly in amphibians, and is important for informing our basic understanding of sex-specific divergence in the physiology, anatomy, and ecology of species more broadly. Using a controlled laboratory e...

This paper investigates the juvenility limit and structure–property relationship in secondary quality beech ( Fagus sylvatica L.) oak Quercus petraea (Matt.) Liebl.). The juvenile wood occupies a very small area near pith. stabilization of different parameters varies over time. Adding microfibril angle (MFA) grain to MOE prediction model significantly improves model, despite little variation bo...

In order to evaluate the physical and mechanical properties of plantation Japanese larch wood, various indicators were measured with reference Chinese national standards. The characteristics growth ring on end face wood samples captured, mean latewood percentage being 21.4% width 3.24 mm. Relationships between characteristics, percentages, investigated. results revealed that it is most appropri...
