Pirates, exiles, and empire: English seamen, Atlantic expansion, and Jamaican settlement, 1558–1658

A life of piracy offered marginal men a profession with a degree of autonomy, despite the brand of "outlaw" and the fear of prosecution. At various times throughout history, governments and crowned heads suspended much of their piracy prosecution, licensing men to work as "privateers" for the state, supplementing naval forces. This practice has a long history, but in sixteenth-century England, Elizabeth I (1558-1603) significantly altered this tradition. Recognizing her own weakness in effectively prosecuting these men and the profit they could contribute to the government, Elizabeth began incorporating pirates into the English naval corps in peacetime—not just in war. This practice increased English naval resources, income, and presence in the emerging Atlantic World, but also increased conflict with the powerful Spanish empire. By 1605, making peace with Spain, James VI/I (1603-1625) retracted Elizabeth's privateering promotion, prompting an emigration of English seamen to the American outposts they had developed in the previous century. Now exiles, no longer beholden to the Crown, seamen reverted back to piracy. The Carolinas and Jamaica served as bases for these rover communities. In 1650, the revolutionary leader Oliver Cromwell (1649-1658) once again recognized the merits of such policies. Determined to demonstrate his authority and solidify his rule, Cromwell offered citizenship and state support to Caribbean exiles in exchange for their aiding of his navy in the taking of Spanish Jamaica. Official chartering of Port Royal, Jamaica served as reward for these men's efforts and as the culmination of a century-long cycle of piracy legislation, creating one of England's most lucrative colonies in the middle of a traditionally Spanish Caribbean empire. Through legal and diplomatic records, correspondence, and naval and demographic records from England and Spain, this dissertation explores early modern piracy/privateering policy and its impact on the development of the Atlantic World. European disputes and imperial competition converged in these piracy debates with significant consequences for the definitions of criminality and citizenship and for the development of Atlantic empire.

Aedes aegypti pharate first instar aseasonal quiescence cues anticipatory plasticity with implications for urban vector ecology and control

The eggs of the dengue fever vector Aedes aegypti possess the ability to undergo an extended quiescence period hosting a fully developed first instar larvae within its chorion. As a result of this life history stage, pharate larvae can withstand months of dormancy inside the egg where they depend on stored reserves of maternal origin. This adaptation known as pharate first instar quiescence, allows A. aegypti to cope with fluctuations in water availability. An examination of this fundamental adaptation has shown that there are trade-offs associated with it. ^ Aedes aegypti mosquitoes are frequently associated with urban habitats that may contain metal pollution. My research has demonstrated that the duration of this quiescence and the extent of nutritional depletion associated with it affects the physiology and survival of larvae that hatch in a suboptimal habitat; nutrient reserves decrease during pharate first instar quiescence and alter subsequent larval and adult fitness. The duration of quiescence compromises metal tolerance physiology and is coupled to a decrease in metallothionein mRNA levels. My findings also indicate that even low levels of environmentally relevant larval metal stress alter the parameters that determine vector capacity. ^ My research has also demonstrated that extended pharate first instar quiescence can elicit a plastic response resulting in an adult phenotype distinct from adults reared from short quiescence eggs. Extended pharate first instar quiescence affects the performance and reproductive fitness of the adult female mosquito as well as the nutritional status of its progeny via maternal effects in an adaptive manner, i.e., anticipatory phenotypic plasticity results as a consequence of the duration of pharate first instar quiescence and alternative phenotypes may exist for this mosquito with quiescence serving as a cue possibly signaling the environmental conditions that follow a dry period. M findings may explain, in part, A. aegypti's success as a vector and its geographic distribution and have implications for its vector capacity and control.^
