Ray Traits of Juvenile Wood and Mature Wood: Pinus massonia and Cunninghamia lanceolata [PDF]
Forests, 2021 Ray traits affect secondary xylem development and wood properties. Pinus massonia and Cunninghamia lanceolata, commercially important timber species, were chosen to study the differences in wood ray traits of juvenile versus mature wood. Seven ray traits, i.e., percentage of rays, ray spacing, ray number, uniseriate ray height, fusiform ray height, ray

Infection intensity and severity of Ranavirus transmission in juvenile wood frogs. [PDF]
OecologiaAbstract Ranaviruses are responsible for mass die offs of wood frog (Lithobates sylvaticus) tadpoles. What happens in between epidemics is less clear, but juvenile (metamorphosed) stages are hypothesized to move Ranaviruses among wetlands and introduce or reintroduce these viruses into wetlands, initiating new outbreaks. A key question is under

Anatomical properties of Eucalyptus grandis wood and transition age between the juvenile and mature woods [PDF]
European Journal of Wood and Wood Products, 2015 The present study is aimed at evaluating the anatomical characteristics of Eucalyptus grandis wood and the transition age between the juvenile and mature woods. Four trees of 23-year-old E. grandis were used. The juvenile, transition and mature wood zones were found by fiber length measurement from the pith to the bark. Samples were taken from juvenile
