Saproxylic Insights: Unveiling Gut Microbial Dynamics in Forest Floor Invertebrates and Their Frass in the Tallaganda Region, NSW
… hosts: saproxylic velvet worms, saprophagous wood cockroaches, funnel web spiders, and their immediate environment, the frass. All individuals used in this study were found in the Tallaganda Region of New South Wales, Australia. This study utilized the V4-V5 region of the 16S rRNA gene …

Long-term patterns of mortality and regeneration in near-natural woodland
… disturbance were recorded in six native lowland woods around Britain, using a series of permanent transects/plots established during the 1950-80s. Records were made including the position and status of trees, shrubs, established seedlings, dead wood and canopy gaps.<br></br>2. The stands …

Long-Term Disturbance Histories Of Managed And Natural Mixed-Hardwood Forests Of Central Indiana
… inventory of an eastern deciduous mixed-hardwood forest. I used a long-term study of the Purdue Davis Agricultural Center mixed-hardwood deciduous forest stands in east-central Indiana, U.S.A. I examined transitions of species composition and structure in a natural, relict forest as a …

The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropods
… microhabitat structures (i. vegetation, ii. dead wood. iii. litter cover). The spider were collected in a block design by pitfall traps (n=72) in a 4-week interval. To reveal key environmental factors affecting the spider distribution abiotic and biotic habitat parameters (e.g. vegetation …

Methane Fluxes from Living and Dead Trees in a Temperate Forest
… those from foliage, branches, wounds, and coarse woody debris. Recent instrumentation advances allow rapid and accurate measurements of relatively low methane flux rates in-situ; this thesis takes advantage of such technology to explore methane fluxes from these tree components in northern …

Overstory structure and detrital dynamics of ponderosa pine forests: insights into fire behavior and its carbon consequences
… the long-term dynamics of detrital pools (dead wood, litter, duff). Woody detritus accumulated quickly after a fire, as dead material fell. This peak then decomposed before pool size increased again as new material fell. Litter accumulated monotonically, and was most strongly related to …

The simulation modeling of supply logistics of forest biomass in British Columbia
… Interior BC forests has led to huge volumes of dead wood that exceed the capacity of the lumber industry. One way to make the most value of the surplus wood is to use it as the feedstock for bioenergy. The forest biomass can be supplied through conventional (roadside residuals), full-tree …

Assessing indicators of forest sustainability using lidar remote sensing
… error. The amount and variability of living and dead wood in a forest stand is an important indicator of forest biodiversity. In the second study, the capacity of lidar to estimate the distribution of living and dead trees within forests is investigated. Twenty-two field plots were established in …

Timber supply and economic impact of mountain pine beetle salvage strategies
… were modelled with a timber supply model (Woodstock) which uses a linear programming type II optimization approach. Performance of the model was assessed over a range of indicators such as NPV, profit, salvage proportion, species composition, inventory levels, and non-recoverable volume. …

The dendrochronology of the Navajo pueblitos of Dinetah
… site tree-ring database illuminates early Navajo wood use behavior, the temporal and spatial patterning of pueblito site occupations, and relationships between climate and the Navajo occupation and abandonment of Dinetah. Wood use behaviors identified at the pueblito sites include construction …

Wood cell wall modification with hydrophobic molecules
Wood is used for many applications because of its excellent mechanical properties, relative abundance and as it is a renewable resource. However, its wider utilization as an engineering material is limited because it swells and shrinks upon moisture changes and is susceptible to degradation by …
