For instance a high MfA has been found detrimental for solid wood properties. Although it is assumed that there is a c...

Abstract Key message Larger differences of maximum load among families were found in mature wood compared to juvenile wood, suggesting the possibility improving with higher resistance rupture and maintaining characteristics material Larix kaempferi (Lamb.) Carr. by selecting specific mating parents. Context Because from L. trees is used for construction lumber, properties bending should be focu...

Juvenile songbirds on spring migration travel from tropical wintering sites to temperate breeding destinations thousands of kilometres away with no prior experience to guide them. We provide a first glimpse at the migration timing, routes, and stopover behaviour of juvenile wood thrushes (Hylocichla mustelina) on their inaugural spring migration by using miniaturized archival geolocators to tra...

Pyriproxyfen, a juvenile hormone analog insect growth regulator (IGR), is a recommended insecticide for the control of container-inhabiting mosquitoes. The effects of eight container substrates (three plastics, wood, tire rubber, clay pot, concrete, and glass) were studied on reduction of bio-efficacy of pyriproxyfen for Aedes albopictus (Skuse) in the laboratory. Insect growth regulator-bioass...
