The Insect Factory in Wood Decay

Studies in Wood Decay

Circumstantial evidence is presented which indicates that Polyporus volvatus is parasitic. Cultures of Polyporus volvatus and Fomes igniarius may be obtained from the young sporophores by the tissue method. In Polyporus volvatus the presence of the following enzymes was demonstrated: esterase, maltase, lactase, sucrase, raffinase, diastase, inulase, cellulase, hemicellulase, glucosidase, rennet...

Insect-mediated nitrogen dynamics in decomposing wood

Abstract. 1. Wood decomposition is characterised by complex and poorly understood nitrogen (N) dynamics with unclear implications for forest nutrient cycling and productivity. Wood-dwelling microbes have developed unique strategies for coping with the N limitations imposed by their substrate, including the translocation of N into wood by cord-forming fungi and the fixation of atmospheric nitrog...

Personal exposure to wood dust among workers in NekaChoob factory in 2013

Background and Purpose: Inhalation of hardwood dust may produce a range of adverse health effects in the upper and lower respiratory system, including asthma, along with Sino-nasal cancer and nasopharyngeal cancer. This study was carried out to evaluate personal exposure to wood dust among workers in chipboard and furniture production saloons in Neka Choob factory, Iran. Materials a...

Evaluation Cif Wood Decay in Experimental Work

The Earliest Evidence of Holometabolan Insect Pupation in Conifer Wood

BACKGROUND The pre-Jurassic record of terrestrial wood borings is poorly resolved, despite body fossil evidence of insect diversification among xylophilic clades starting in the late Paleozoic. Detailed analysis of borings in petrified wood provides direct evidence of wood utilization by invertebrate animals, which typically comprises feeding behaviors. METHODOLOGY/PRINCIPAL FINDINGS We descr...
