In the 1990s global warming was envisioned scientifically as being highly influential and pronounced at high latitudes (Mitchell et al. 1990; Maxwell 1992). Since then, impacts of climate change have been confirmed, especially in the indisputable data of increased air surface temperatures in both the Alaskan Arctic and Europe (Overpeck et al. 1997; Keyser et al. 2000; Serreze et al. 2000; EEA 2004). Ostensibly, climate change is currently affecting life in the world's ecosystems with intensified ramifications of escalating temperatures (IPCC 2007). The Arctic has had a rapid increase in mean temperatures over the past few decades, twice the rate of the rest of the world (ACIA 2005). Its warmest year ever recorded was in 2007 (Richter-Menge et al. 2008). Biomes already seem to be changing owing to climate differences, indicated by observations of enhanced plant growth at high northern latitudes (Myneni et al. 1997) and mid-latitudes (Nemani et al. 2003), landscape-level shifts in species ranges, decline in species populations (McCarthy et al. 2001), and changes in species diversity (EEA 2004). Continuing Arctic climate change will therefore have the effect of encouraging forest expansion into tundra biomes, and the tundra vegetation as we know it will greatly change, shifting in its extent, distribution, and species composition. These changes will probably be unprecedented compared with those of past millennia.
Arrays of CdTe nanowires have been grown on conductive, flexible Mo substrates by the vapor-liquid-solid technique. A method of forming the arrays on a largely continuous CdTe film is described. For producing nanowire solar cells, this structure provides the advantage of preventing shunts. Nanowires having diameters in the range 100-500 nm and lengths up to 100 μm were generated. The influence of growth temperature, time and pressure on the morphology of deposited layers was investigated, and a mechanism for the generation of layer/nanowire combinations is postulated. Characterization by SEM, TEM and low temperature photoluminescence is presented.
As a result of more intensive rearing and specialization in modern production, pigs are often moved to a new location. In addition, mixing of previously unacquainted pigs usually occurs following transportation to new facilities. Mixing of pigs results in agonistic behaviour (Ewbank, 1976) eliciting social stress (Arnone and Dantzer, 1980) that may produce gastro-intestinal disturbances which adversely affect pig performance.
