Tree Cover In The Surrounding Landscape Reduces Burrowing Owl (Athene Cunicularia) Occupancy Of Black-Tailed Prairie Dog Colonies In South Dakota, Jason P. Thiele, Kristel K. Bakker, Charles D. Dieter

Natural Resource Management Faculty Publications

Burrowing Owl (Athene cunicularia) population declines have led to the owl’s designation as a species of conservation concern in South Dakota. Burrowing Owls nest primarily in black-tailed prairie dog (Cynomys ludovicianus) colonies, but a significant proportion of colonies in South Dakota are not occupied by owls. We studied the influence of landscape-level habitat variables on colony selection by Burrowing Owls. We used call-playback surveys to document presence or absence of Burrowing Owls at 613 prairie dog colonies throughout western and central South Dakota. We used a geographic information system to calculate the percent cover of prairie dog colonies, grassland, cropland, …

Andean Condor Cliff And Parental Care Behavior: A Behavioral Study Of A Chick And His Free-Living Parents On The Peñón Del Isco, Ecuador, Ellie Cohn

Independent Study Project (ISP) Collection

Andean condors (Vultur gryphus) are a Near Threatened species of New World Vulture found throughout the Andes region of South America. Their population has been significantly diminished in the country of Ecuador due to threats primarily related to habitat loss and persecution by humans. High chick and juvenile mortality also threaten populations and as a result, investigation of wild Andean condors’ cliff behavior and parental care are necessary in order to develop informed and effective conservation management plans. A 22-day observational study was conducted, monitoring a known breeding pair of Andean condors and their approximately three-month-old male chick on the …

Nesting Success Of Dickcissel (Spiza Americana) And Non-Breeding Grassland Bird Use Of Northwest Arkansas’ Remnant And Restored Tallgrass Prairies, Alyssa L. Derubeis

Graduate Theses and Dissertations

Dwindling populations of North American grassland birds are linked to habitat loss. Tallgrass prairie only covers 3% of its pre-settlement-era range. Small-scale restoration projects attempt to increase acreage for prairie avifauna, and while some breeding grassland species are present at these sites, nesting success and non-breeding use are still largely unknown. Both life history aspects are required for effective grassland bird conservation. My first objective was to access nest success of the Dickcissel (Spiza americana) at two remnant and two restored tallgrass prairies in Northwest Arkansas. From May-August 2017 and 2018, I found 114 nests that I monitored to determine …

Iceland's Migratory Birds In Changing Environmental Conditions: An Interactive Synthesis, Frances J. Duncan

Independent Study Project (ISP) Collection

Human-driven changes to environmental conditions alter the habitats, behaviors, and migration patterns of migratory species. Changes in temperature, vegetation, and precipitation are just some of the factors contributing to shifts in phenology, demography, and distribution of migratory birds. These changes are driven by anthropogenic climate change and amplified by human land-use change, and are especially intense at high latitudes. This project creatively communicates the effects of environmental changes on three species of migratory birds in Iceland—the northern wheatear, the Greenland white-fronted goose, and the black-tailed godwit—using principles of storytelling and game design. The resulting interactive product is a game that …

Trends In Nectar Production And Concentration Of Hummingbird-Pollinated Flowers: An Investigation Of Three Flowers Of The Ecuadorian Cloud Forest: Palicourea Demissa, Mezobromelia Capituligera, And Kohleria Affinis, Grace Palmer

Independent Study Project (ISP) Collection

Nectar concentration and sugar production both impact and are impacted by pollinator activity through a complex system of coevolution. Additionally, a variety of morphological and environmental factors influence the nectar properties of animal-pollinated flowering plants. Nectar concentration and nectar production rate (NPR) of three hummingbird-pollinated plants, Palicourea demissa, Mezobromelia capituligera, and Kohleria affinis, were measured. These flowers occur and were studied in the southern section of the Chocó-Andean subtropical montane rainforest, in the Pichincha province of Ecuador. Flowers were bagged for 24 hours and sampled at approximate two-hour time intervals for 12 or 24 hours. Nectar concentration and sugar production …

Avian Upsloping In The Tropics: Myioborus Miniatus And Myioborus Torquatus Abundance In Different Altitudinal Ranges In Boquete, Chiriquí, Panama, Julie Yoon

Independent Study Project (ISP) Collection

Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. This study measured abundance of M. miniatus and M. torquatus populations at different altitudinal ranges by point …

Quiscalus Mexicanus Vocalization Pitch And Traffic Noise In Breeding Populations Along The Cinta Costera Highway And In Downtown Gamboa, Panamá, Benjamin P. Gregory

Independent Study Project (ISP) Collection

Urbanization is one of the fastest-growing threats to the biodiversity of the planet, but not all animals are extirpated by the drastic environmental changes of urbanization, and many are even able to thrive in urban landscapes. Behavioral flexibility is often cited as one reason that successful urban animals can so rapidly adapt to a foreign environment with novel stressors. A well-studied example of urban behavioral flexibility is urban-living birds singing with higher-frequency songs in areas with high levels of traffic noise. The present study investigated this trend in Quiscalus mexicanus, an icterid bird with a huge vocal range, highly sexually …

Impacts Of Anthropogenic Waste On Tasmanian Pacific Gull (Larus Pacificus) Diet, Anne Bartlett

Independent Study Project (ISP) Collection

Plastic pollution is one of the foremost environmental issues that the world is currently experiencing. The effects of plastic pollution are great and range from leaching of hazardous chemicals into the environment to ingestion of plastic waste by wildlife, including seabirds. Due to the high rates of plastic consumption by seabirds, many recent studies have been performed to determine the biological impacts of plastic consumption on various seabird species. The Pacific Gull (Larus pacificus) is the world’s largest sea gull and the only gull endemic to Australia, yet very limited information exists on this species. This study examines the impacts …

Greater Sage-Grouse Survival, Breeding Ecology, Resource Selection, And West Nile Virus Prevalence On The Eastern Fringe Of Their Range, Lindsey Anne Parsons

Electronic Theses and Dissertations

The greater sage-grouse (Centrocercus urophasianus) is a sagebrush (Artemisia spp.) obligate species that has experienced population declines over the past several decades. Sage-grouse are a species of conservation concern throughout the Intermountain West and are considered a species of greatest conservation need in South Dakota. Numerous studies have documented drivers of demographic performance at the core of their distribution; however, relatively few studies have examined sage-grouse inhabiting the eastern extent of their range, in South Dakota. We sought to examine sage-grouse space use in multiple seasons, estimate survival, and determine factors affecting nest success in South Dakota …

Cerulean Warbler (Setophaga Cerulea) And Associated Species Response To Operational Silviculture In The Central Appalachian Region, Gretchen Emily Nareff

Graduate Theses, Dissertations, and Problem Reports

In this study, I assessed the response of Cerulean Warblers (Setophaga cerulea) and 5 additional songbird species to timber harvests prescribed through operational silviculture. The research took place in relatively contiguous mature deciduous forests in 4 states in the central Appalachian region—Kentucky, Pennsylvania, Virginia, and West Virginia, USA.

For the first part of the study, I collected Cerulean Warbler abundance and territory data through point counts and territory mapping, respectively. I used the point count data to model Cerulean Warbler abundance pre- and post-harvest at 5 study areas (Kentucky [n=1], Virginia [n=2], West Virginia [n=2]) and post-harvest at …

Identifying An Optimal Bald Eagle Monitoring Program For Southwest Alaska National Parks, Rebecca Kolstrom

Electronic Theses and Dissertations

The Southwest Alaska Inventory and Monitoring Network includes bald eagle monitoring as part of their Vital Signs Monitoring Plan. Lake Clark National Park and Preserve, Katmai National Park and Preserve, Kenai Fjords National Park, and Wrangell – St. Elias National Park and Preserve monitor bald eagles annually, albeit slightly differently among parks. Since monitoring decisions involve multiple objectives and stakeholders, there was a need for a structured approach to identify an optimal monitoring program. We used a structured decision making process and an iterative, four-round Delphi Process to collect information about long-term bald eagle monitoring from experts. We collected information …
