Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t. groenlandicus x pearyi) caribou were tracked with satellite collars in 1993-2009 in the Northwest Territories, Nunavut, and northern Alberta. Using satellite location data and hierarchical and fuzzy cluster analyses, I verified that Cape Bathurst, Bluenose-West, Bluenose-East, Bathurst, Beverly, Qamanirjuaq, and Lorillard barren-ground subpopulations were robust; the Queen Maude Gulf and Wager Bay barren-ground subpopulations were distinct. Dolphin and Union island caribou formed one population; boreal caribou formed two distinct subpopulations. Females in robust subpopulations were structured by strong annual spatial affiliation; those in distinct subpopulations were spatially independent and structured by migratory connectivity, movement barriers, and/or habitat discontinuity. An east-west cline in annual-range sizes and path lengths supported the subpopulation structure identified for migratory barren-ground caribou. I analyzed satellite location data to determine parturition dates and activity periods for all caribou ecotypes. For parturition dates I found a north-south cline for boreal caribou, west-east cline for migratory barren-ground caribou, and ecotype and subspecies clines for boreal and barren-ground caribou. Based on annual changes in movement rates I identified eight activity periods for boreal and tundra-wintering, 10 for mountain woodland, and 12 for migratory barren-ground caribou. Based distribution and movements, boreal caribou avoided seismic lines during periods when females and calves were most vulnerable to predators or hunters. They crossed fewer seismic lines and travelled faster when they crossed them than expected. Caribou avoided areas ≤400 m from seismic lines where they could space away from them suggesting that they perceive these as risky areas. I defined secure habitats as areas that were >400 m from anthropogenic linear features. Population growth rates were higher in areas where they had access to secure unburned habitat and where most of that was in patches >500 km2. Critical habitat for boreal caribou is a habitat state that provides “security” from predation risk and facilitates the effectiveness of their anti-predator strategies. / Ecology

This dissertation is mainly based on the reading of three American novels to explore how female characters deal with their illegitimate pregnancies and how their solutions re-shape their futures and affect their inner growth. Chapter 1 discusses Dorinda Oakley's premarital pregnancy in Ellen Glasgow's Barren Ground and draws the circle of limits from Barbara Welter's "four cardinal virtues" (purity, submissiveness, domesticity, and piety) which connect to the analogous female roles (daughter, sister, wife, and mother). Dorinda's childless survival reconstructs a typical household from her domination and absence of maternity. Chapter 2 examines Ántonia Shimerda's struggles and endurance in My Ántonia by Willa Cather before and after Ántonia gives birth to a premarital daughter. Ántonia devotes herself to being a caring mother and to looking after a big family although her marriage is also friendship-centered. Chapter 3 adopts a different approach to analyze Charlotte Rittenmeyer's extramarital pregnancy in The Wild Palms by William Faulkner. As opposed to Dorinda and Ántonia who re-enter domesticity to survive, Charlotte runs out on her family and dies of a botched abortion. To help explain the aftermath of illicit pregnancies, I extend or shorten John Duvall's formula of female role mutations: "virgin>sexually active (called whore)>wife" to examine the riddles of female survival and demise. The overall argument suggests that one way or another, nature, society, and family are involved in illegitimately pregnant women's lives, and the more socially compliant a pregnant woman becomes after her transgression, the better chance she can survive with her baby.
