Martinez-Solano I, Lawson R. 2009. Escape to Alcatraz: evolutionary history of slender salamanders (Batrachoseps) on the islands of San Francisco Bay. BMC Evolutionary Biology 9: 38. doi:10.1186/1471-2148-9-38
Love the title, but the ideas in the paper seem pretty interesting, too. The idea is that the salamanders were on the islands before they were islands! They were inhabiting hilltops when the water level was lower, then got stuck as rising water levels turned hilltops into islands.
