In normal conditions, marine animals are well equipped to fight off infection from the plethora of bacteria and viruses lurking in the oceans. However, that means having a hearty immune system that can react quickly if they get hurt. Researcher are finding that areas with low oxygen, such as within and around dead zones, and high carbon dioxide can wreak havoc on coastal animals' ability to ward off disease. They are finding that for animals living in polluted areas such as these, it takes only half as much bacteria to be lethal.

Radioactive boar on the rise in Germany

As Germany's wild boar population has skyrocketed in recent years, so too has the number of animals contaminated by radioactivity left over from the Chernobyl nuclear meltdown. Government payments compensating hunters for lost income due to radioactive boar have quadrupled since 2007. It's no secret that Germany has a wild boar problem. Stories of marauding pigs hit the headlines with startling regularity: Ten days ago, a wild boar attacked a wheelchair-bound man in a park in Berlin; in early July, a pack of almost two dozen of the animals repeatedly marched into the eastern German town of Eisenach, frightening residents and keeping police busy; and on Friday morning, a German highway was closed for hours after 10 wild boar broke through a fence and waltzed onto the road.

Even worse, though, almost a quarter century after the Chernobyl nuclear meltdown in Ukraine, a good chunk of Germany's wild boar population remains slightly radioactive - and the phenomenon has been costing the German government an increasing amount of money in recent years. According to the Environment Ministry in Berlin, almost €425,000 ($555,000) was paid out to hunters in 2009 in compensation for wild boar meat that was too contaminated by radiation to be sold for consumption. That total is more than four times higher than compensation payments made in 2007.

The reason for the climbing payments, of course, has more to do with Germany's skyrocketing wild boar population than with an increase in radioactive contamination. "In the last couple of years, wild boar have rapidly multiplied," a spokesman from the Environment Ministry said. "Not only is there more corn being farmed, but warmer winters have also contributed to a boar boom." Numbers from the German Hunting Federation confirm the population increase. In the 2008/2009 season, a record number of boar were shot, almost 650,000 against just 287,000 a year previously.

Many of the boar that are killed land on the plates of diners across Germany, but it is forbidden to sell meat containing high levels of radioactive caesium-137 - any animals showing contamination levels higher than 600 becquerel per kilogram must be disposed of. But in some areas of Germany, particularly in the south, wild boar routinely show much higher levels of contamination. According to the Environment Ministry, the average contamination for boar shot in Bayerischer Wald, a forested region on the Bavarian border with the Czech Republic, was 7,000 becquerel per kilogram. Other regions in southern Germany aren't much better. Wild boar are particularly susceptible to radioactive contamination due to their predilection for chomping on mushrooms and truffles, which are particularly efficient at absorbing radioactivity. Indeed, whereas radioactivity in some vegetation is expected to continue declining, the contamination of some types of mushrooms and truffles will likely remain the same, and may even rise slightly - even a quarter century after the Chernobyl accident.
