On wood surfaces and in planar section, zones lines appear as narrow sharply delineated dark within visibly altered (“spalted”) by the decay process. In intact wood, zone define an irregular volume of decaying wood. They are primarily aggregations melanised hyphae that enclose being decayed a single genetic individual fungus. industry for specialty products, highly valued, especially decorative...
Novel species of fungi described in this study include those from various countries as follows: Australia: Banksiophoma australiensis (incl. Banksiophoma gen. nov.) on Banksia coccinea, Davidiellomycesaustraliensis (incl. Davidiellomyces gen. nov.) on Cyperaceae, Didymocyrtis banksiae on Banksia sessilis var. cygnorum, Disculoides calophyllae on Corymbia calophylla, Harknessia banksiae on Banks...
An evaluation of a pulsed-eurrent resistance meter ("Shigometer®", Model No. 7950) for facilitating detection of decay was performed on wood blocks of giant sequoia heartwood and of white fir sapwood. As decay progressed over a 12-week incubation period, a trend of lower meter readings was obtained, confirming reported field measurements of other workers. Variability in meter readings in situat...
Fallen tree trunks (‘nurse logs’) are important recruitment sites for trees in temperate forest, however nurse log use is seldom reported in tropical forests. We predicted that logs should be important for the regeneration of small-seeded tropical pioneer species because surface leaf litter and competition with established vegetation reduces the establishment success of these species from soil ...
Copper tolerant fungi are known for more than 60 years but the complete mechanisms of copper tolerance by these fungi are still not fully understood. Copper tolerance has previously been linked to oxalic acid excretion by copper tolerant brown rot fungi. The oxalic acid then reacts with copper in the wood to form an insoluble and therefore less toxic copper oxalate. It has been suggested that c...
Arborists commonly investigate the extent of stem decay to assess likelihood failure when conducting tree risk assessments. Studies have shown that: (i) arborists can sometimes judge internal based on external signs; (ii) sophisticated tools reliably illustrate decay; and (iii) assessing components be highly subjective. We recruited 18 experienced assessors who held International Society Arbori...
Filtering-estimating the state of a partially ob servable Markov process from a sequence of observations-is one of the most widely stud ied problems in control theory, AI, and com putational statistics. Exact computation of the posterior distribution is generally intractable for large discrete systems and for nonlinear con tinuous systems, so a good deal of effort has gone into developing r...
