A household production model is constructed in the context of a subsistence economy, influenced by fluctuating rainfall, increasing populations, and relationships to the natural resource base. Households are modelled as attempting to optimally allocate their resources among four sectors: agriculture, woodlands (with wood and non-wood sub-sectors), livestock and urban. Simulations show that, alt...

Damage to the Fukushima Nuclear Power Plant by the recent earthquake and tsunami that hit northern Japan should stimulate consideration of alternative sources of energy. In particular, if managed appropriately, the 25.1 million ha of Japanese forests could be an important source of wood biomass for bioenergy production. Here, we discuss policy incentives for substituting wood bioenergy for nucl...

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...

(1) Wood is a widely available raw material on the market, which satisfies industrial demand and used both as source of biomass for wood materials industry in broad sense energy-supplying purposes. These areas prove functional values possibilities directional use low-quality products. One factors influencing overall balance form quality that cannot be further processed mechanically. This study ...

We assessed the relationship between riparian management and stream quality along five southeastern Minnesota streams in 1995 and 1996. Specifically, we examined the effect of rotationally and continuously grazed pastures and different types of riparian buffer strips on water chemistry, physical habitat, benthic macroinvertebrates, and fish as indicators of stream quality. We collected data at ...

Many termite species use clay to build foraging galleries and mound-nests. In some cases clay is placed within excavations of their wooden food, such as living trees or timber in buildings; however the purpose for this clay is unclear. We tested the hypotheses that termites can identify load bearing wood, and that they use clay to provide mechanical support of the load and thus allow them to ea...
