Small volumes of timber from Acacia and Eucalyptus woodlands of western Queensland, Australia, have achieved high prices in specialty timber markets, which has aroused the
interest of landholders. A postal survey of 225 domestic and international specialty timber product manufacturers was undertaken
to determine current utilisation of these lesser-known species, establish their suitability for various product markets, ascertain
desirable timber dimensions and condition, and estimate potential future domestic and international demand. An overall response
rate of 31% was achieved. Responses indicated that current utilisation of these timbers is probably not more than 200 m3/yr. Nevertheless, respondents generally indicated that western Queensland hardwoods are highly suited to the manufacture
of specialty timber products, including small-scale furniture items, custom knife handles and musical instruments, and that
they have high export potential. Some furniture and musical instrument manufacturers indicated they would be willing to pay
up to $3,000/m3 and $30,000/m3 respectively, for small volumes of high-quality appropriately processed western hardwoods. Large, well-directed marketing
campaigns will be necessary to expand specialty timber markets for western Queensland hardwoods. 相似文献

Portable sawmilling trials with Acacia aneura (mulga) and A. cambagei (gidgee) have been undertaken to estimate the private landholder costs associated with small-scale timber production from
woodlands in western Queensland, Australia. A time study of harvesting and milling operations facilitated estimation of landholder
labour input requirements. The scarcity and small size of millable logs, coupled with the prevalence of timber defects, make
harvesting and portable sawmilling of western Queensland acacias an expensive undertaking for landholders. The cost of producing
sawn timber that meets the High Feature (HF) grade of Australian Standard AS2796 is estimated at between A$3,000/m3 and A$3,400/m3 of HF timber. 相似文献

To study the evolution of recombination rates in apes, we developed methodology to construct a fine-scale genetic map from high-throughput sequence data from 10 Western chimpanzees, Pan troglodytes verus. Compared to the human genetic map, broad-scale recombination rates tend to be conserved, but with exceptions, particularly in regions of chromosomal rearrangements and around the site of ancestral fusion in human chromosome 2. At fine scales, chimpanzee recombination is dominated by hotspots, which show no overlap with those of humans even though rates are similarly elevated around CpG islands and decreased within genes. The hotspot-specifying protein PRDM9 shows extensive variation among Western chimpanzees, and there is little evidence that any sequence motifs are enriched in hotspots. The contrasting locations of hotspots provide a natural experiment, which demonstrates the impact of recombination on base composition. 相似文献

Non-industrial private forests (NIPFs) and public forests in the United States generate many non-market benefits for landholders
and society generally. These values can be both enhanced and diminished by wildfire management. This paper considers the challenges
of supporting economically efficient allocation of wildfire suppression resources in a social cost-benefit analysis framework
when non-market values are important. These challenges include substantial gaps in scientific understanding about how the
spatial and temporal provision of non-market values are affected by wildfire, the limited utility of benefit transfer in wildfire
assessment, a lack of studies that have estimated marginal willingness-to-pay to conserve non-market values, violation of
consumer budget constraints, and the infeasibility of valuing indigenous cultural heritage. These challenges present serious
impediments to adapting price-based decision-support tools to accommodate non-market values and support decision-making consistent
with contemporary federal wildfire policy. Departure from the historic range and variability of ecological conditions is proposed
as a complementary framework to support wildfire management decisions when non-market values are important on NIPF and public
forestland.

The large and unutilised native forest timber resource on traditional Wik land on Cape York Peninsula, Australia, could be
managed for timber production to contribute to Wik socio-economic objectives. Wik elders have a set of forestry objectives
and envisage that these will be best achieved by a timber industry selling unprocessed logs and woodchips. On the other hand,
Balkanu Cape York Development Corporation, a government-funded indigenous community development organisation, anticipate that
an industry utilising high-technology equipment and producing dried and dressed finished products including strip-flooring
will best satisfy Wik forestry objectives. The Wilderness Society envisages small-scale ‘community development’ activities
such as protable sawmilling and niche market furniture manufacture as being appropriate types of forestry activities on Wik
land. Goal programming analysis of forest use opportunities indicates that Wik forestry objectives are unlikely to be best
satisfied by adopting the timber utilisation options espoused by any one of the stakeholder groups. 相似文献
