If you are hosting a Darwin Day event on February 12th, you need a life-size Darwin so partiers can pose for photographs. Contact me and I’ll send you the file … all you have to do is print him, glue him to a thick board, and cut around the image. Ideally, you just tell somebody else to do all of that. When he’s ready, just stand him up in a central location at your event. For details, see my Portable Charles Darwin page.
If you need stickers for Darwin’s birthday (February 12th) I finally got the image up on Redbubble. These stickers are great for kids’ lunch boxes, skateboards, and prizes for biology class. Redbubble claims the stickers will survive 18 months outside, which is great news for those not allowed to bring evolution material inside the house. I’ll eventually put up some translated versions, too, so if you need this in Arabic, be patient.
If you’re curious, I designed this image because I wanted a way to show my fondness for evolution but thought the “evolution fish” (the standard image for science and reality fans) was a tad too offensive. More details on my Charles Darwin Has A Posse page.

To get myself excited about Spring, I typed up some thoughts on how to protect fruit and vegetable gardens from squirrels. Have a look if that relates to your life.
Below are three photographs of mistletoe seeds I took at La Selva Research Station in Costa Rica. Seeds were most likely deposited by birds perching on the signs, but I’m not sure whether the birds scraped off the seeds (which can be extremely sticky, due to presence of viscin threads) or simply pooped them. If the latter was the case, the bulk of the poop is long gone, but it rains enough in the tropics for that to happen. There are threads visible on the top photograph, so I’m going to guess that the seeds were attached to the birds somehow, and the birds scraped them off onto the sign.
By the way, mistletoe are parasitic plants … which is why it’s amusing (to me) that they were on a sign. Although they are clearly green and can photosynthesize, they’ll eventually need the water (and other xylem contents) from a host. Under those adhesive pads there is (or will soon be) a haustorium that will attempt to burrow into the substrate in hopes of finding host xylem. If I lived at the station I’d naturally record how long these beasties survived, but staff probably clean off the seedlings every few weeks just so it doesn’t look to nasty. Some species can apparently last a year as self-sufficient seedlings.
Some photographs I took during a visit to La Selva Research Station in 2008. Old, but recently discovered they hadn’t transferred to my site when I bailed on Flickr.
I was stuck inside a small room for most of stay (I was consulting for Organization for Tropical Studies), unfortunately, so not as many pics as I’d like. The full album (approximately 50 images) is below. I wish OTS would hire me again.
This little spider is a golden orb weaver (Nephila clavipes), I think:
