Master of Arts / Department of History / Charles W. Sanders / On June 3, 1825, William Clark, Superintendent of Indian Affairs, and eleven representatives of the “Kanzas” nation signed a treaty ceding their lands to the United States. The first to sign was “Nom-pa-wa-rah,” the overall Kansa leader, better known as White Plume. His participation illustrated the racial chasm that had opened between Native- and Anglo- American worlds. The treaty was designed to ease pressures of proximity in Missouri and relocate multiple nations West of the Mississippi, where they believed they would finally be beyond the American lust for land. White Plume knew different. Through experience with U.S. Indian policy, he understood that land cessions only restarted a cycle of events culminating in more land cessions. His identity as a mixed-blood, by virtue of the Indian-white ancestry of many of his family, opened opportunities for that experience. Thus, he attempted in 1825 to use U.S. laws and relationships with officials such as William Clark to protect the future of the Kansa. The treaty was a cession of land to satisfy conflicts, but also a guarantee of reserved land, and significantly, of a “halfbreed” tract for mixed-blood members of the Kansa Nation. Mixed-blood go-betweens stood for a final few moments astride a widening chasm between Anglo-American and native worlds. It was a space that less than a century before offered numerous opportunities for mixed-blood people to thrive as intermediaries, brokers, traders, and diplomats. They appeared, albeit subtly, in interactions wherever white and Native worlds overlapped. As American Indians lost their economic viability and eventually their land, that overlap disappeared. White Plume’s negotiation of a reserve for his descendants is telling of a group left without a place. In bridging the two worlds, mixed-bloods became a group that by the mid-nineteenth century was defined as “other” by Anglo-American and Indians alike. This study is the first to track these evolving racial constructs and roles over both time and place. Previous studies have examined mixed-blood roles, but their identity is portrayed as static. This study contends that their roles changed with the proximity and viability of full-blood communities with which white officials had to negotiate.

Habitat loss and predation are threatening many shorebird populations worldwide. While habitat preservation often is preferable, sometimes habitat needs to be restored or created in order to stave off immediate declines. The Great Plains population of piping plovers (Charadrius melodus) was listed as threatened in 1986, and habitat loss and predation appear to be limiting the growth of this population. On the Missouri River, piping plovers nest on sandbars, but the damming of the mainstem of the Missouri in the mid-twentieth century reduced the natural capacity of the Missouri River to create sandbar habitat. In 2004, the United States Army Corps of Engineers (USACE) implemented a habitat creation project on the Gavins Point Reach of the Missouri River (stretch of river immediately downriver from the Gavins Point Dam) in an effort to promote recovery of piping plovers and the endangered least tern (Sternula antillarum). The USACE built 3 sandbars in 2004 – 2005 and built another sandbar on Lewis and Clark Lake in 2007. We studied the population dynamics of piping plovers in relationship to this newly engineered habitat. We monitored 623 nests on 16 sandbar complexes, to evaluate habitat selection, determine the factors affecting nesting success, and compare nesting success between natural and engineered habitat. From these 623 nests, we banded 357 adults and 685 chicks to investigate the factors affecting adult and juvenile survival. We used a logistic-exposure model to calculate nest survival. Adult and juvenile survival was calculated using Cormack-Jolly-Seber based models in Program MARK. We used the estimates from these studies to create a matrix population model for piping plovers nesting on the Gavins Point Reach. We used this model to predict the effects of engineered habitat on the population growth rate. Piping plovers selected for engineered sandbars and against natural and natural/modified habitats. Daily survival rate (DSR) on engineered habitats was significantly higher than on natural or natural modified habitats (log odds: 2.71, 95% CI: 1.20 – 6.08). Predator exclosures around nests did not affect DSR after controlling for the effects of date, nest age, and clutch size. Piping plover juvenile survival to recruitment was negatively related to nesting density on the relatively densely populated engineered sandbars. On the less dense natural sandbars, survival to recruitment was positively correlated with density. Adult survival did not appear to be related to density within our study. Movement within the study area was related also to density. Juveniles from densely populated engineered sandbars were more likely to leave engineered habitat to nest on natural sandbars than were juveniles hatched on less densely populated engineered sandbars. Movements among sandbars by breeding adults suggested that adults preferred engineered habitat. It is possible that juveniles moved to natural habitats because they were unable to compete with adults for the more desirable engineered habitats. Adults and juveniles emigrated from the study area at a higher rate after the 2006 breeding season, a year when water discharge was higher, nesting densities were higher, and reproductive success was lower (as a result of predation) than in the other years. Deterministic modeling suggested that engineered habitat significantly increased population growth. Decreased productivity over time and associated predicted negative population growth suggest that the amount of engineered habitat created was inadequate to sustain population growth, and/or that relatively high water discharge and nesting densities coupled with low reproductive rates and high emigration rates could lead to rapid declines in the plover population. Continued research is needed to determine the effects of these factors on long-term population growth. Our results suggest that habitat creation could be a viable short-term solution to population declines in shorebird populations limited by habitat loss, but high densities and increased predation associated with habitat creation indicate that other, long-term solutions may be required. / Ph.

Globally, riparian ecosystems are in decline due to anthropogenic modifications including damming, channelization and the conversion of the floodplain for human use. These changes can profoundly affect riparian species as many have adapted to the historical dynamism of these ecosystems. On the managed Missouri River, an imperiled shorebird, the piping plover (Charadrius melodus) uses riverine sandbars to breed. From 2004 to 2009, due to limited breeding habitat and low population numbers, the U.S. Army Corps of Engineers constructed 255 ha of sandbar habitat to benefit piping plovers and least terns (Sternula antillarum). During the breeding seasons of 2010 and 2011, historically high flows resulted in the creation of 1,887 ha of suitable sandbar habitat. Our study compared the demographic response and the condition of piping plovers to these anthropogenic and natural habitat creation events. From 2005–2014 we monitored 1,071 nests, and from those nests we uniquely banded 968 adults and 2,021 piping plover chicks. We obtained 405 egg (clutch) mass measurements, 1,285 mass measurements from 633 adults, and 7,093 mass measurements from 1,996 plover chicks resulting in 3,175 mass measurements from 654 broods of chicks. We also collected 3,347 invertebrate prey samples. We used a random effects logistic exposure model to estimate nest success, a random effects Cormack-Jolly-Seber model in RMARK to estimate pre-fledge chick survival and the Barker model in RMARK to estimate hatch-year (HY) and after hatch-year (AHY) survival and fidelity to our study area. We then used estimates from these analyses to calculate reproductive output, reproductive output necessary for a stationary population, and population growth (λ). For adult condition and egg (clutch) mass we used generalized linear mixed regression, and for pre-fledge chick growth rates we used a modified Richard's model to estimate the effects of habitat type (pre- vs. post-flood). We also tested for differences in invertebrate prey abundance between habitat types using negative binomial regression. Our results indicated that AHY survival varied throughout our study and was lowest during the flood (2010 and 2011). We found that nest success, pre-fledge chick survival, reproductive output, and HY survival and fidelity were consistently higher on the flood-created habitat than engineered habitat, leading to sustained population growth after the flooding, as compared to just one year of population growth prior to the flood. Unlike pre-flood engineered habitat, the demographic parameters we measured did not decrease as the post-flood habitat aged. These differences were related to increased sandbar habitat, low nesting densities, and decreased nest and chick predation on the post-flood habitat. Although we hypothesized that increased demographic rates would be reflected by increased piping plover condition following the flood, we found that our measured condition variables (adult mass, clutch mass, and pre-fledge chick growth rates) remained unchanged following the flood. We also found evidence that clutch mass, chick growth rates and invertebrate prey abundance decreased as the post-flood sandbar habitat aged. As the condition of individuals did not appear to contribute directly to the increased demographic rates following the flood, we suggest that the change in density-dependent predation pressure may explain the discrepancy. As many ecosystems have previously been altered, it's rare that ecologists have the opportunity to compare management practices with natural ecosystem processes. Results from this study suggest that management intervention may not be an equivalent substitute for natural ecosystem processes and provide insight on future management of riparian ecosystem. / Master of Science / Worldwide, riverine ecosystems are declining, which has had a negative effect on many species. On the managed Missouri River, a threatened shorebird, the piping plover (<i>Charadrius melodus</i>), likes to nest on unvegetated sandbars with saturated, or ‘muddy’ areas where they, and their chicks can feed on insects. Historically, flooding of the river created new sandbar habitat and scoured vegetation off of existing sandbars. However, the current river management regime, including dams and channelization, means that the river floods less, and over time sandbars become vegetated and eventually erode away. From 2004 to 2009 the U.S. Army Corps of Engineers built sandbars for piping plovers to use for nesting and raising their chicks. In 2011, the Missouri River flooded as a result of increased mountain snow and spring precipitation. Although devastating at the time, the flood created an abundance of new sandbar habitat for piping plovers to use, nearly ten times more habitat than was available before. To understand what effect the flood and the newly created sandbars had on piping plovers, we collected data on the Missouri River from 2005–2014. We monitored nests to figure out how many hatched, and used color bands on both adults and chicks to see how many survived throughout the season and over the years. We also weighed piping plover eggs, chicks, and adults and collected insect prey samples. Following the flood, more nests hatched, more chicks survived to fledging, and more chicks survived from one year to the next than during any of the years prior. This success led to the population of piping plovers nearly doubling each year. Because the flood created so much habitat, piping plovers were still able to successfully hatch nests and raise their chicks, even with the sandbars eroding and vegetating over time. Although we thought that the increase in rates such as survival and population growth, would be reflected by increased egg masses, adult masses, and chick masses, we found that they remained unchanged following the flood. We also found evidence that egg masses and chick masses were related to the amount of insect prey. Following the flood, less nests and chicks were eaten by predators such as, mink, crow, and great-horned owls, and we think this is a result of decreases in nesting densities which may have made nests and chicks harder to locate. These results indicate that the amount of habitat available to nesting piping plovers is an incredibly important factor in the population growth of this imperiled species.

In the following nine linked stories, characters from disparate backgrounds and socio-economic strata converge in a rural community along the Missouri river in central Montana. A Texas-based oil exploration and production company takes up residence in the area, causing a stir in the neighborhood. Long-time local residents experience their daily lives amid a tourist driven economy and reaffirm their aspirations to leave despite significant obstacles and limitations. In "Show Me the Way to Go Home," a young waitress is stranded after a car accident and seeks help from residents living on the single row of houses in the area. In "Give Death Grace," a resident artist leaves to resolve her tumultuous past with her father. In "A Good Little Fisherwoman," a woman deals with the repercussions of her recent reproductive decisions during a fishing trip. In "Little Fires," a local man deals with the tragic burn injury of a child while also facing deeply rooted resentments with his mother. In "Dwelling," an aging local must decide whether or not she will sell her home to two strangers. In "Other Important Areas of Functioning," a woman decides to discontinue her mood stabilizing medications in favor of a more natural lifestyle. While this place means something different to each of these characters, they all coexist while facing individual challenges.
