Real-Time Measurement of the Viscoelasticity of Green Juvenile Wood of Japanese Cedar at High Temperature [PDF]

, 2010
Changes in the viscoelasticity of green juvenile and mature wood during high-temperature drying were measured in real time. For each measurement, a 180-mm-long specimen of Japanese cedar (Cryptomeria japonica), its supporting system, a magnetic driver ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Strength properties of juvenile and mature wood in black locust (Robinia pseudoacacia L.)

, 2007
This study was undertaken to investigate the strength properties of juvenile and mature wood in black locust (Robinia pseudoacacia L.). Wood specimens were prepared from various stem heights, up to 9 m, of five naturally-grown black locust trees, 21-37 ...

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

ESTIMATIVA DA IDADE DE SEGREGAÇÃO DO LENHO JUVENIL E ADULTO DE Carya illinoinensis (Wangenh) K. Koch POR MEIO DE PARÂMETROS ANATÔMICOS DA MADEIRA

Ciência Florestal, 2010
Knowledge of the demarcation of juvenile and mature wood is essential both for wood technology and forest management. Thinning, in most cases, must take into account this parameter, as the juvenile wood has inferior characteristics compared to mature ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

DEMARCATION OF JUVENILE AND MATURE WOOD OF Corymbia citriodora

, 2015
This paper had the objective of determining the transition regions between the juvenile and mature wood of Corymbia citriodora (Eucalyptus citriodora) of 29 years of age from the Experimental Station of Forest Science (EECFA-LCF/ESALQ-USP), located in Anhembi, in the State of São Paulo. The regions of juvenile and mature wood were characterized through

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

River Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.
