What's really happening on the Barro Colorado Island 50 ha forest plot?

Hubbell's neutral model of biodiversity is founded on tree inventory data for Barro Colorado Island โ€“ย which don't fit the model. A better one is the compound abundance distribution involving the geometric series. A preprint of the newly submitted BCI paper is here:

A review for a Little Caesarโ€™s somewhere by Kevin S: 

Stopped into this Little Caesars just trying to get a $6 pizza and ended up in a full on action movie. Just as I grabbed my order, this furious dude barges in yelling about how I cut him off in traffic earlier.
Before I can even respond, he throws a punch but then out of nowhere the guy behind the counter jumps over it like he's been waiting for this moment his whole life and just beats the living hell out of the guy. The guy ran off and the cashier just dusted himself off. I said "are you ok man" and he looked me dead in the eye and said "B*tch, this is Little Caesars. We always hot and ready."
Five stars. Will absolutely return.

Newly Discovered "Bone-Digesting" Cells Help Burmese Pythons Consume Every Last Bit Of Their Prey No wonder theyโ€™re taking over the Everglades, although other snakes were found to have these cells too.

Burmese pythons donโ€™t believe in waste, digesting not only the muscle and fat of their prey, but the bones as well, thanks to newly discovered cells.
