Notes for May 3rd

• Cephalopods and pain.
• How effective is land use zoning on conserving ecosystems?  Well, if your index of ecosystem health is bluegills (and large woody debris), the answer is moderately effective, but highly variable.
• I'm not sure why anyone is at all surprised that cougars get caught in wolf snares.  The question is how could you prevent this while still allowing wolf trapping.  Another question might be:  Why do we need to trap wolves anyway?
• Everyone seems to be talking about this paper on the transfer of genes from fungi to aphids, making aphids the only (known) animal to produce carotenoids.  Unfortunately, I can't read this paper because Science requires money for knowledge, but you can read about it elsewhere if you like.
