The Race: On Tiny Skinks and Contemplating GG IV

It is the holiday season in this part of the world, and the California Academy of Sciences (where most of us island biologists work) is absolutely packed.  I thought I would share a few images of our public floors.  We scientists and our collections and laboratories are behind the scenes in an off-limits wing, and I would bet that a lot of our public visitors still do not realize we do science here; last year we had 2.3 million of them from all over the world.

So if it is the holiday season, why am I here in the lab?  Part of the answer is that I am planning our next expedition, GG IV. A small group of us are going back to the islands in February with several rather specific missions… I will describe our plans in the next blog.  Meantime, here are some updates:

Dr. Tom Daniel’s publication with Estrela Figueirido on the Acanth flowers of São Tomé and Príncipe was just published today, and we are taking copies over to islands with us.  As usual, we have provided an abstract in Portuguese.

Afroablepharis on Sao Tome – D Lin phot-GG II

Above is a leaf litter skink called Afroablepharis. Until we started working on the island fauna, both islands were thought to be inhabited by the same species (then called Panaspis africanus).  We provided tissue samples of some of our GGI material from both islands to colleagues at the University of Madeira. Dr. Jose Jesus and his colleagues found that the two populations were genetically distinct and that each island had its own, separate species.

On-going island projects (RCD construct)

Unfortunately, all of the original specimens from which tissues were taken were subsequently lost in the international mail and were never returned to the Academy.  Since we still have additional preserved skinks from the same localities on both islands, my Research Assistant, Lauren Scheinberg (left, above), is carefully examining all of them to find the physical differences we would usually (but not always) expect to find in two species distinct from one another. We are now formally collaborating with Dr. Jesus and his Madeira team.

Above, on the right, is Lisette, who is still working on the jita snakes (earlier blogs), and this has also expanded into a much larger project with several international collaborators and samples from mainland Africa.  The shrew comparison on the lower left is one of our goals for GG IV. We will meet up with Ricardo Lima on São Tomé, the man who rediscovered this unlikely creature.

More detail on GG IV when I return from Ethiopia.

Here’s the parting shot:
