Luke and Morgan hanging out with Charlie
Overfishing is most often implicated as the cause of decreasing fish stocks and that makes a lot of logical sense if you’ve ever seen a large commercial trawler unload its catch. But there very well might be another force at work in the precipitous decline in fish stocks worldwide: pollution. The basic premise is that it takes resources to deal with pollutants that normally would be given to growth and reproduction. Through polluting the ocean, we have selected for the fish individuals that can most effectively divert those resources, inadvertently also selecting for smaller fish that reproduce less. That has huge implications for the fish’s population dynamics and potentially total fish stock. More details below the fold…

Charlie hangs out with Jim Toomey, author of Sherman’s Lagoon
Dear Representative Boehner,
Congratulations on your party’s recent election victories. Your speech at the end of the night was particularly touching, and your personal story is inspirational. The election results do seem to signify that many Americans are not happy with how the Democratic party has been running Washington, and some change will likely be good for the country. As a scientist, however, I am deeply troubled by some of what I’m hearing about the new Republican House majority, particularly about global climate change policy.

Bad Charlie!
Last week, I posted a review of National Geographic’s Great Migrations. I loved it and encouraged others to watch.
If you didn’t catch it yet, there will be new episodes this coming Sunday. You don’t just have to take my word for it, though. Lots of blogs have been talking about this series.
