    Ecotourism seems like it should be a win-win. Visitors get to experience exciting, often exotic locales and see creatures in their natural habitats. The money raised through these visits goes to local communities and to preserving ecosystems.

    Last weekend I watched Jurassic Park for the first time in years. Still awed by the seemingly realistic, long-extinct animals, I started wondering: What would happen if they escaped the remote Pacific island where they had been created and made it to land? The only dino in the movie series to make it to a continent was a Tyrannosaurus rex in The Lost World: Jurassic Park. And it had been shipped to San Diego by stupid humans.

    Cities are brimming with wildlife. There are coyotes, bats, insects and, of course, birds, to name a few. Of those groups, the birds are probably the ones that most people care about, and the species that we most want to encourage to make homes in our yards. But how much do our backyards really matter?

    Climate change is heating up the planet, and species are moving toward the poles, up mountains and deeper into the oceans. For most, there’s a natural end to this journey - the edge of a continent, for instance, or the summit of a mountain.

    • Pink Salmon Threatened by Freshwater Acidification

    As carbon dioxide levels in the atmosphere rise, the world’s oceans are absorbing some of the gas and slowly becoming more acidic. That acidification impedes the chemical reaction that many marine species use to make calcium carbonate shells and skeletons. Fish were once thought to be immune to the drop in pH, but a growing amount of evidence show that these species, too, are affected. Now comes evidence that acidification might be a problem for freshwater fish as well.

    For millions of Americans, Thanksgiving is an excuse to gorge on turkey, stuffing and pumpkin pie, despite the warnings that overeating, even for a day, can be incredibly unhealthy. But for a Burmese python, enormous meals are the norm. These huge snakes - they can reach up to 6.7 meters in length - may go weeks or months without eating, so they have to make their meals count. And they have many adaptations that let them consume quantities of food that would be impossible for a human to take in.

    Earthworms are great for soil, right? Well, not always. In places where there have been no earthworms for thousands of years, foreign worms can wreak havoc on soils. And that can cause a cascade of problems throughout an area’s food web. Now comes evidence that invader worms in the Upper Great Lakes may be stressing the region’s sugar maples.

    It may not be polite to eavesdrop, but sometimes, listening in on others’ conversations can provide valuable information. And in this way, humans are like most other species in the animal world, where eavesdropping is a common way of gathering information about potential dangers.

    Some 90 percent of the world’s trade spends at least part of its journey at sea. Ships carry everything from oil to cars to food to rubber duckies. They also carry huge amounts of ballast water to increase their stability. When the weight of the water isn’t needed - because the ship has taken on cargo, for instance - it gets discharged.

    There’s a fabulously named drunken monkey hypothesis that posits that humans’ love of alcohol comes from our primate ancestors. Those primates, the theory goes, got an evolutionary advantage from being able to eat lots of fermenting fruit and the ethanol that forms in the process.

    February 2011 was a bad month for seabirds living on the Midway, Kure and Laysan atolls. A winter storm swept across this portion of the North Pacific, with winds exceeding 115 kilometers per hour that whipped water across the low-lying islands.
