Avian Influenza
Avian Influenza has become one of the biggest threats for human and animal health. The old paradigm was that the disease in waterfowl, poultry, pigs and man was caused by separate viruses that each stayed reasonably well within their own niche. The only danger to man was considered being infected by pigs, being the mixing vessel, where avian and human influenza viruses could come together and exchange genetic material to form new viruses that ...

Plant Ecology, Herbivory, and Human Impact in Nordic Mountain Birch Forests
The successful long-term sustainable management of forests is dependent on our knowledge of their history, present state, and responses to changing environmental conditions. In this light, the text evaluates the Nordic mountain birch ecosystem with examples from different sites in the Nordic countries and Scotland. The authors analyse vegetation and soils, and investigate the influence of climate change, insect pests, grazing pressure by sheep ...

Vegetation Dynamics of Mongolia
Mongolia is an expansive land-locked country, tilted by tectonic forces to the North, that experiences extremes of continental climate. Moisture-carrying wind currents are scarce so that the land has extended highs and lows in its environment. Culturally the people are mostly nomadic, having been sustained for centuries by an economy based on domestic livestock grazing. There is a saying that, 'As the noses go, so goes Mongolia', referring ...
