Yet the bird does something that conservation biologists might considered useful for sustaining ecosystems: it spreads the seeds of native Hawaiian plants. Get rid of the Japanese white-eye, and you get rid of its service.

For the last two decades, strange things have been happening to frogs. Some frog populations have high rates of limb deformities, while others have high incidences of what is known as “intersex” — traits associated with both males and females, such as male frogs whose testes contain eggs.

I sat down recently with ecologist David Skelly to talk about the strange things happening to frogs these days. A few years back, scientists found evidence suggesting that pesticides were causing sexual deformities in frogs that lived near farms. Now Skelly is finding that the situation is actually a lot more dire for frogs in suburbs and cities. Over at Yale Environment 360, you can read our Q & A about what sort of chemical cocktail may be making eggs grow in the testes of male frogs–and what it may all mean for us fellow vertebrates.

Here’s the video of the lecture I gave last week at Stony Brook University, which was the basis of my recent blog post. I’ve uploaded the slides as a pdf here. (You can read the slides online or download them by going to the File drop-down menu.) I’m not sure what the ideal combination of video and slides would be…if anyone has any suggestions, let me know.
[Update–the video url got switched around. This should work now…]
