Witkowski A Dissertation submitted to the Faculty of the Graduate School, Marquette University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Milwaukee, Wisconsin May 2010 ABSTRACT “JUSTICE WITHOUT PARTIALITY”: WOMEN AND THE LAW IN COLONIAL MARYLAND, 1648-1715 Monica C. Witkowski Marquette University, 2010 What was the legal status of women in early colonial Maryland? This is the central question answered by this dissertation. Women, as exemplified through a series of case studies, understood the law and interacted with the nascent Maryland legal system. Each of the cases in the following chapters is slightly different. Each case examined in this dissertation illustrates how much independent legal agency women in the colony demonstrated. Throughout the seventeenth century, Maryland women appeared before the colony’s Provincial and county courts as witnesses, plaintiffs, defendants, and attorneys in criminal and civil trials. Women further entered their personal cattle marks, claimed land, and sued other colonists. This study asserts that they improved their social standing through these interactions with the courts. By exerting this much legal knowledge, they created an important place for themselves in Maryland society. Historians have begun to question the interpretation that Southern women were restricted to the home as housewives and mothers.

  • Chesapeake Bay and the Restoration Colonies by 1700, the Virginia Colonists Had Made Their Fortunes Primari
    9/24: Lecture Notes: Chesapeake Bay and the Restoration Colonies By 1700, the Virginia colonists had made their fortunes primarily through the cultivation of tobacco, setting a pattern that was followed in territories known as Maryland and the Carolinas. Regarding politics and religion: by 1700 Virginia and Maryland, known as the Chesapeake Colonies, differed considerably from the New England colonies. [Official names: Colony and Dominion of Virginia (later the Commonwealth of Virginia) and the Province of Maryland] The Church of England was the established church in Virginia, which meant taxpayers paid for the support of the Church whether or not they were Anglicans. We see a lower degree of Puritan influence in these colonies, but as I have mentioned in class previously, even the term “Puritan” begins to mean something else by 1700. In the Chesapeake, Church membership ultimately mattered little, since a lack of clergymen and few churches kept many Virginians from attending church on a regular basis, or with a level of frequency seen in England. Attending church thus was of somewhat secondary importance in the Virginia colony and throughout the Chesapeake region, at least when compared to the Massachusetts region. Virginia's colonial government structure resembled that of England's county courts, and contrasted with the somewhat theocratic government of Massachusetts Bay and other New England colonies. And again, they are Theocratic – a government based on religion. Now even though they did not attend church as regularly as those living in England, this does not mean that religion did not play a very important role in their lives.

  • Camping Places (Campsites and Cabins) with Carderock Springs As
    Camping places (campsites and cabins) With Carderock Springs as the center of the universe, here are a variety of camping locations in Maryland, Virginia, Pennsylvania, West Virginia and Delaware. A big round of applause to Carderock’s Eric Nothman for putting this list together, doing a lot of research so the rest of us can spend more time camping! CAMPING in Maryland 1) Marsden Tract - 5 mins - (National Park Service) - C&O canal Mile 11 (1/2 mile above Carderock) three beautiful group campsites on the Potomac. Reservations/permit required. Max 20 to 30 people each. C&O canal - hiker/biker campsites (no permit needed - all are free!) about every five miles starting from Swains Lock to Cumberland. Campsites all the way to Paw Paw, WV (about 23 sites) are within 2 hrs drive. Three private campgrounds (along the canal) have cabins. Some sections could be traveled by canoe on the Potomac (canoe camping). Closest: Swains Lock - 10 mins - 5 individual tent only sites (one isolated - take path up river) - all close to parking lot. First come/first serve only. Parking fills up on weekends by 8am. Group Campsites are located at McCoy's Ferry, Fifteen Mile Creek, Paw Paw Tunnel, and Spring Gap. They are $20 per site, per night with a maximum of 35 people. Six restored Lock-houses - (several within a few miles of Carderock) - C&O Canal Trust manages six restored Canal Lock-houses for nightly rental (some with heat, water, A/C). 2) Cabin John Regional Park - 10 mins - 7 primitive walk-in sites. Pit toilets, running water.

  • Gut Content Metabarcoding Unveils the Diet of a Flower‐Associated Coastal
    ECOSPHERE NATURALIST No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator PAUL MASONICK , MADISON HERNANDEZ, AND CHRISTIANE WEIRAUCH Department of Entomology, University of California, Riverside, 900 University Avenue, Riverside, California 92521 USA Citation: Masonick, P., M. Hernandez, and C. Weirauch. 2019. No guts, no glory: Gut content metabarcoding unveils the diet of a flower-associated coastal sage scrub predator. Ecosphere 10(5):e02712. 10.1002/ecs2.2712 Abstract. Invertebrate generalist predators are ubiquitous and play a major role in food-web dynamics. Molecular gut content analysis (MGCA) has become a popular means to assess prey ranges and specificity of cryptic arthropods in the absence of direct observation. While this approach has been widely used to study predation on economically important taxa (i.e., pests) in agroecosystems, it is less frequently used to study the broader trophic interactions involving generalist predators in natural communities such as the diverse and threatened coastal sage scrub communities of Southern California. Here, we employ DNA metabarcoding-based MGCA and survey the taxonomically and ecologically diverse prey range of Phymata pacifica Evans, a generalist flower-associated ambush bug (Hemiptera: Reduviidae). We detected predation on a wide array of taxa including beneficial pollinators, potential pests, and other predatory arthropods. The success of this study demonstrates the utility of MGCA in natural ecosystems and can serve as a model for future diet investigations into other cryptic and underrepresented communities. Key words: biodiversity; blocking primers; DNA detectability half-life; Eriogonum fasciculatum; food webs; intraguild predation; natural enemies. Received 24 January 2019; accepted 11 February 2019.
