In our modern-day human culture, decomposition and decay have often come to be viewed quite negatively, with the former mainly associated with things that are rotten, have a bad smell and are generally symptomatic of death, while the latter is similarly viewed as very undesirable, whether it be in terms of urban decay, or, on a much more personal level, tooth decay. Forests naturally include some trees that have succumb to diseases, pests, storm events, or old age – some disease, decay, and tree death is normal in a healthy forest. Damaged, dead, deformed, and dying trees are hotspots of biodiversity and biological legacies.

The trick to controlling wood spalting, it seemed, was a thorough understanding of the biological process. Wood decay fungi in the phylum Basidiomycota, which includes all mushrooms, come in two primary groups: the brown rots, which predominate on conifers, and . Additionally, in another recent study involving a beech forest, the hypothesis of, which predicts community changes during forest rotations, was refuted from a functional view point. However several studies considering the effects of silvicultural practices on soil fauna found important impacts on soil forest fertility/productivity and in the.

Different biological decay functions are considered based on process-based modeling and inventory data across various climate zones. For all scenarios, the changes in cumulative radiative forcing (CRF) are calculated over a year period, to evaluate the short- and long-term contributions of forest residue to climate change by: Forest residues of two age classes (less than 1 year old and between 1 and 2 years old) were chipped and piled ( to m piles) on the cutting site.
Chip piles were inoculated with decay fungi Cited by: Different biological decay functions are considered based on process-based modeling and inventory data across various climate zones.

Forest bioenergy has become a significant portion of the energy used by the pulp and paper sector (58% in ) largely because it makes economic sense to convert into energy what might otherwise be a waste product to be sent. Abstract. Botrytis cinerea is the causal agent of gray mold, and is considered the most important pathogen responsible for postharvest decay of fresh fruit and vegetables, having a wide range of hosts.
Infections by B. cinerea that cause postharvest decay usually occur at the field stage, and they can remain latent until storage when B. cinerea can develop from rotted fruit next to healthy. Logging residue decomposition rates were determined in four conifer forest ecosystems in the State of Washington, U.S.A.
(coastal western hemlock, Puget lowland Douglas-fir, high-elevation Pacific silver fir, and eastern Cascade ponderosa pine), by examining wood density changes in a series of south-facing harvest areas with residues of different ages.
Decaying wood is related to nutrient cycling through its role as either a sink or source of nutrients. However, at micro scales, what is the effect of decaying logs on the physical, chemical, and biotic characteristics of the soil underneath.
We took samples from a 0 to 5 cm depth under and a 50 cm distance away from decaying logs (Dacryodes excelsa and Swietenia macrophylla) at 2 stages of.
Abstract. Many organisms, both macro- and micro- flora and fauna, live in the forest floor and mineral layers of the forest soil. Macrofloras include plant roots, which function in water storage, drainage, aeration, and nutrient cycling in soil by their proliferation, death, and decay.
Introduction. Logging residues, also known as forest slash, are branches and tops left on the forest site after logging. In Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris L.) residues correspond to about 55 and 20% of the stem volume, respectively (Hakkila, ).In the past, the logging residues were uneconomical to gather and were left in the forest.
This volume is the proceedings of a symposium on straw decay and a workshop on assessment techniques held at Hatfield Polytechnic April, It is divided into sections on the relevance of straw decay to agriculture: effects of straw residues (5 papers); decay of untreated straw by natural processes (4 papers); decay of treated straw (13 papers); industrial applications of straw decay.

Pyrolysis output weight ratio of syngas to biochar is Teak (Tectona grandis L.f.) is one of the most important tropical hardwood tree species, which is widely planted in Indonesia.
Wood properties are strongly influenced by forest management conditioning further utilization of wood. In Indonesia, teak wood has been supplied from the state forests (Perhutani) for long rotation teak and from community teak plantations for short rotation teak.
Organic chemical compounds produced during the decomposition of fresh residues also help to bind soil particles together and give the soil good structure. Organic molecules directly released from cells of fresh residues, such as proteins, amino acids, sugars, and starches.

Look for fire scars, mechanical wounds and conks (fruiting bodies of decay fungi). If striking the bole with the flat end of an axe produces a hollow sound, there is probably a lot of heartwood decay.
Heartwood rot may be hidden and require close examination to find. This is an excellent book because it tells a compelling and accessible story based on forest ecosystems ecology.
There are a few informational errors here and there but overall, this is an engaging telling of a very complex story. I enjoyed this book and the Reviews: the forest floor and in other moist environments.
But it was only a century ago, inthat wood decay was recognized as a biological process. The pioneering German forest pathologist Robert Hartig was the first to prove that fungi are the cause rather than the product of wood decay (3).
Forty years later Oshima (4) demonstrated that some. Long-term litter decay and forest floor leaching in Pinus contorta ecosystems, southeastern Wyoming. Journal of Ecology. Yavitt, J. B.; Fahey, T.

Canadian Journal of Forest. The first generations of WPC were considered to be very resistant to biological decay, and one reason for this was the slow moisture transport into the material achieved by the polymer matrix.
However, the outermost layer of the composite has been shown capable of reaching moisture levels high enough to initiate biological decay (Wang and. Due to rising concerns about losing old-growth forest species, retention of a few trees in clear felled stands started to become part of Fennoscandian forest management in the s, with retention of aspen trees (Populus tremula).Growing interest in harvesting methods other than clear felling resulted in the first VRF experiments with biological sampling, NaturKultur and Härjedalen, in Review of Plant Pathology (RoPP) is a fully searchable abstracts database of internationally published research.
