There are two key factors behind this trend. For passenger transport, the determining factor is the spectacular growth in car use. The number of cars on European Union (EU) roads saw an increase of three million cars each year from 1990 to 2010, and in the next decade the EU will see ...
We predict that the high levels—and structural diversity—of secoiridoids present in the UK group may provide a robust reservoir of anti- feeding deterrents to mitigate future herbivore threats such as the Emerald ash borer. Iridoid glycosides are a large class of natural products prevalent in ...
We collected water samples approximately every 10 d from both the NO3− and unamended treatment effluent, as well as each corresponding reservoir influent, to assess biogeochemical processes as a result of microbial activity in each reactor. We measured dissolved inorganic carbon (DIC; CO2 +...

This scenario requires maintenance of the polymorphism for a long time (~10 myr) and thus the presence of balancing selection. Some examples are known of the long-term maintenance of polymorphisms during ape evolution. For instance, the polymorphism at the ABO blood groups is thought to have...
Besides, several other immunizations may be warranted (yellow fever, typhoid, and cholera), depending on the destination(s) and itinerary, and prophylaxis for malaria may be advisable as well. Improved knowledge and understanding of the main vaccine designs and co...
