Composition And Ecology Of Avian Communities Along Elevational Gradients In Borneo, Ryan Christian Burner
LSU Doctoral Dissertations
A primary goal of ecology is to explain the diversity and distribution of organisms. Species distributions can be a function of abiotic factors, species interactions, dispersal limitations, and history, but the relative importance of these factors is widely debated. Elevational gradients are useful systems for studying these effects because many of these factors vary predictably with elevation, and because elevational gradients are replicated many times across the earth. However, few quantitative surveys of Southeast Asian bird communities have been conducted along elevational gradients. In this study, I surveyed birds using point counts and measured habitat and temperature across primary forest …

Whooping Crane Use Of Riverine Stopover Sites, David M. Baasch, Patrick D. Farrell, Shay Howlin, Aaron T. Pearse, Jason M. Farnsworth, Chadwin B. Smith
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Migratory birds like endangered whooping cranes (Grus americana) require suitable nocturnal roost sites during twice annual migrations. Whooping cranes primarily roost in shallow surface water wetlands, ponds, and rivers. All these features have been greatly impacted by human activities, which present threats to the continued recovery of the species. A portion of one such river, the central Platte River, has been identified as critical habitat for the survival of the endangered whooping crane. Management intervention is now underway to rehabilitate habitat form and function on the central Platte River to increase use and thereby contribute to the survival of whooping …

Birds are essential components of most ecosystems and provide many services valued by society. However, many populations have undergone striking declines as their habitats have been lost or degraded by human activities. Terrestrial grasslands are vital habitat for birds in the North American Prairie Pothole Region (PPR), but grassland conversion and fragmentation from agriculture and energy-production activities have destroyed or degraded millions of hectares. Conservation grasslands can provide alternate habitat. In the United States, the Conservation Reserve Program (CRP) is the largest program maintaining conservation grasslands on agricultural lands, but conservation grasslands in the PPR have declined by over 1 …

Student Creative and Scholarly Works
Long term biological studies are rare but incredibly valuable for examining natural phenomena. Data collected over many years or decades allows for analyses of trends that would never be apparent in a single season. The research presented here is the completion of the second annual field season of a long term study to analyze biodiversity trends at the St. Norbert Abbey. Using visual searches, live trapping, and trail cameras, the biodiversity and abundance of species were examined. Special emphasis was placed on small mammals, though other groups were observed and documented. The goals of this project are to (1) collect …
Public Land Management On The Upper Mississippi: Exploring Relationships Between Management Imperatives And Ecosystem Biodiversity,

Public Land Management On The Upper Mississippi: Exploring Relationships Between Management Imperatives And Ecosystem Biodiversity, Hunter Colleen Ridley
Geography: Student Scholarship & Creative Works
Presently, public land management structure tends to disregard the interconnected nature of the social and ecological systems within managed landscapes. Since these social and ecological systems so heavily influence the identity of landscapes, it is critical that land managers understand the interactions and effects land management has with ecological structure and function. This knowledge helps land managers create more effective, sustainable, and efficient management plans and decisions. This research uses a portion of Upper Mississippi River as a case study for analyzing and discussing public land management on the Mississippi and how its structure may be influencing the ecological identity …

Revisiting The Historic Distribution And Habitats Of The Whooping Crane, Jane E. Austin, Matthew A. Hayes, Jeb A. Barzen
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Understanding the historic range and habitats of an endangered species can assist in conservation and reintroduction efforts for that species. Individuals reintroduced into a species’ historic core range have a higher survival rate compared to individuals introduced near the periphery or outside the historic range (Falk and Olwell, 1992; Griffith et al., 1989). Individuals on the periphery of a species’ range tend to occupy less favorable habitats and have lower and more variable densities than those near the core of their range (Brown, 1984; Brown et al., 1995, 1996). Such conclusions, however, presume that historic habitats have not changed since …

Effects Of Rainbow Trout On Brook Trout Population Size In Tributaries To Lake Superior In Cook County, Minnesota, Craig Tangren
Journal of Earth and Life Science
This study looked at the effects of Rainbow Trout stocking on the size of Brook Trout populations above migratory barriers. Linear mixed effects models were used to determine if there was a relationship between Brook Trout and Rainbow Trout catch rates. Age 1 or older Brook Trout populations were influenced by relative abundance of age 1 or older Rainbow Trout, according to the best supported model based on AIC scores. Population responses varied by stream, ranging along a gradient from high catch rates with a positive relationship to a negative relationship with low relative abundances. Streams with a positive relationship …

Quantitative Monthly Analysis Of Green Plant Biomass Differences Among Burned And Unburned Prairie Sites & Phenology Study, Andrew Koning, Dave Warners
Summer Research
The summer was spent at Flat Iron Lake in Greenville Michigan. Over the ten weeks two studies were performed. The phenology study looked at the timing of native herbaceous wildflowers and sought to analyze a potential effect of climate change. The second study examined the benefits of performing a controlled burn. The study sought to find a quantifiable benefit to controlled burns by looking at monthly statistics of green plant biomass produced on the control side and burned section of prairie.

Floristic Quality Assessments Of Remnant Natural Areas In The Greater Grand Rapids, Michigan Region: Evaluating Botanical Change Since The 1890s, Alan W. Stockdale, Garrett Crow, David P. Warners
Faculty and Professional Research
In 1901, Emma J. Cole, a beloved high school teacher and distinguished botanist, published Grand Rapids Flora. Cole’s floristic inventory remains the most comprehensive botanical study of the greater Grand Rapids, Michigan region, even though this area has experienced significant land- scape alterations since her publication. To address this knowledge gap, in 2014 we embarked on a multiple-year project aimed to discover and reassess the sites Cole described, as well as to catalog other natural remnant locations within the Grand Rapids area. This paper reports botanical invento- ries that were completed at eight sites within Kent County during 2015 and …
