The Beaver Island group in Lake Michigan comprises nine islands ranging from 0.3 to 144 km2, lying approximately 30 km west of Michigan’s Lower Peninsula (LP) and 15 km south of the Upper Peninsula (UP). The islands have been isolated from mainland Michigan for most of their postglacial history, but were connected to the mainland LP during the low-water Chippewa stage (ending about 7400 years before present (YBP)). Although plants and animals could have colonized the islands during the Chippewa period, flooding during the subsequent Nipissing high-water stand means that the smaller islands have been colonized more recently. We analyzed 481 bp of mitochondrial D-loop sequences from woodland deer mice (Peromyscus maniculatus (Wagner, 1845)) on six of these islands in northern Lake Michigan to elucidate the mainland origin and minimum number of colonization events for this species. Surprisingly, the distribution of haplotypes on the islands suggests that the populations on most islands likely had separate recent origins on the mainland UP. Approximate Bayesian computation supports a scenario in which individual islands were colonized separately by distinct groups of mice. Together, the data suggest multiple colonization events from the UP, rather than expansion from a bottlenecked population or a single colonization event.

The founders of successful religious and social movements have received much attention from popular and scholarly writers. Would-be prophets who failed, on the other hand, generally have been ignored, except for a few sensational cases such as those of Sabbatai Sevi, the Jewish messianic pretender of the seventeenth century, or Jim Jones, whose charismatic leadership of a group suicide in Guyana shocked the nation and the world. Yet although religious leaders who fail usually attract little attention, they are often as interesting as those who succeed. Their lives vividly highlight aspects of new religious and social movements which we might otherwise overlook. One of the most remarkable religious failures in nineteenth- century America was James J. Strang, the schismatic Mormon prophet who set up a community of 2,500 on Beaver Island in Lake Michigan and ruled it for nearly ten years until he was assassinated in 1856. Strang was articulate and capable, a compelling intellect and speaker who seemed totally sincere to some yet an utter fraud to others. His life raises fundamental questions about the promise and the dangers inherent in prophetic leadership, not simply in early Mormonism but in many similar movements as well.

Much recent attention has been focused on vegetative survival forms of planktonic diatoms and other algae. There are several reports of extended vegetative survival of the freshwater diatom Melosira in lake sediments. In contrast to those diatoms which form a morphologically distinct resistant spore, Melosira is known to produce physiological resting cells that are indistinguishable in outward morphology from actively growing cells.We used both light and electron microscopy to document and elucidate the sequence of cytological changes during the transition from resting cells to actively growing cells in a population of Melosira granulata from Douglas Lake, Michigan sediments collected in mid-July of 1983.
