Demographic Consequences Of Off-River Nesting For Piping Plover (Charadrius Melodus) And Interior Least Tern (Sternula Antillarum Athalassos) In The Lower Platte River System, Nebraska, Elsa M. Forsberg
School of Natural Resources: Dissertations, Theses, and Student Research
Piping plovers (Charadrius melodus; hereafter, plovers) and interior least terns (Sternula antillarum athalassos; hereafter, terns) are two avian species that nest along the Lower Platte River system (LPRS) in Nebraska. In the LPRS, river sandbars provide natural nesting habitat, but off-river sites provide substantial nesting habitat especially when sandbar habitat is scarce. Although presumed to be important for the persistence of plovers and terns, off-river habitat is not self-sustaining and predicted to decline. Understanding the vital rates of plovers and terns in the LPRS will inform the role of off- river sites in the future conservation …
Rabies Virus Serosurvey Of The Small Indian Mongoose (Urva Auropunctata) Across Multiple Habitats In Puerto Rico, 2014–21, Are R. Berentsen, Mel J. Rivera-Rodriguez, Fabiola B. Torres-Toledo, Amy J. Davis, Richard Chipman, Amy Gilbert
Rabies Virus Serosurvey Of The Small Indian Mongoose (Urva Auropunctata) Across Multiple Habitats In Puerto Rico, 2014–21, Are R. Berentsen, Mel J. Rivera-Rodriguez, Fabiola B. Torres-Toledo, Amy J. Davis, Richard Chipman, Amy Gilbert
USDA Wildlife Services: Staff Publications
The small Indian mongoose (Urva auropuncata) is a rabies reservoir in Puerto Rico and accounts for over 70% of reported animal rabies cases annually. The presence of rabies virus-neutralizing antibodies (RVNA) is often used as a tool to measure exposure to rabies virus in wildlife populations. We conducted a serosurvey of mongooses at 11 sites representing six habitat types across Puerto Rico. We collected a serum sample from 464 individual mongooses during 2014–2021. Overall, 80/464 (17.0%; 95% confidence interval, 14.1–20.9%; 55 male, 23 female, and two sexes not recorded) of individual mongooses sampled across all habitats were RVNA …
Examining A Habitat-Weather Threshold For Northern Bobwhite Populations In The Southwestern United States, John T. Edwards, Fidel Hernández, Andrea Montalvo, Masahiro Ohnishi
Examining A Habitat-Weather Threshold For Northern Bobwhite Populations In The Southwestern United States, John T. Edwards, Fidel Hernández, Andrea Montalvo, Masahiro Ohnishi
National Quail Symposium Proceedings
In semiarid portions of the northern bobwhite (Colinus virginianus; hereafter, bobwhite) geographic distribution, weather is a strong driver of interannual abundance. However, the strength of this relationship may depend on habitat amount. Given this habitat–weather dependence, there is likely to be a threshold value for habitat that determines how strongly a bobwhite population responds to weather. Our objective was to evaluate the relationship between habitat amount and the relative influence of weather on bobwhite abundance in Texas and Oklahoma, USA and determine a potential land-cover threshold value. We collected bobwhite abundance and land-cover data from the Breeding Bird …

Habitat Of The Long-Tailed Wood-Partridge In Central Mexico, David García-Solózano, Crisma Lopez-Sanchez, Edgardo Lopez-González, Carlos González-Rebeles Islas
National Quail Symposium Proceedings
The long-tailed wood-partridge (Dendrortyx macroura; hereafter, wood-partridge) is a forest quail endemic to the temperate forests of the Trans-Mexican Volcanic Belt of central Mexico and is considered threatened according to the Secretariat of the Environment of Mexico. We studied 34 sites within the Natural Resources Protection Area River Basins of the Valle de Bravo, Malacatepec, Tilostoc and Temascaltepec in central Mexico to evaluate wood-partridge habitat during September–December 2019. We evaluated attributes of tree, shrub, and herbaceous vegetation, canopy cover, humidity, slope, and altitude. We also identified vegetation used for nesting, food, and shelter. The scant information published for …
Landscape-Scale Effects Of Habitat And Weather On Scaled Quail Populations, John T. Edwards, Fidel Hernández, David B. Wester, Leonard A. Brennan, Chad J. Parent, Andrea Montalvo, Masahiro Ohnishi
Landscape-Scale Effects Of Habitat And Weather On Scaled Quail Populations, John T. Edwards, Fidel Hernández, David B. Wester, Leonard A. Brennan, Chad J. Parent, Andrea Montalvo, Masahiro Ohnishi
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) have declined over the last half century; however, there is spatial variation within their geographic distribution. Interior populations have increased and peripheral populations have generally decreased. Declines have been attributed to habitat loss and degradation. Scaled quail populations also show interannual fluctuations related to precipitation. Our objective was to determine the relative impact of habitat and weather (i.e., precipitation and temperature) on scaled quail population dynamics. Our hypothesis was that habitat metrics would be more important for decreasing populations whereas weather metrics would be more important for increasing populations. We used publicly available datasets …
Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan Pfeiffer, Bradley F. Blackwell, Travis L. Devault
Collective Effect Of Landfills And Landscape Composition On Bird–Aircraft Collisions, Morgan Pfeiffer, Bradley F. Blackwell, Travis L. Devault
USDA Wildlife Services: Staff Publications
Ninety-three percent of all reported bird strikes occur below 1,067 m, which based on the typical approach and departure angles of aircraft is within 8–13 km of an airport. Concomitantly, the Federal Aviation Administration and the International Civil Aviation Organization recommend that any feature that would attract hazardous wildlife to the approach and departure airspace be restricted. Thus, preventing the establishment of wildlife attractants, such as municipal solid waste landfills (MSWLFs) within 8 km or 13 km extents (U.S. and international recommendations, respectively) of airports, has been recommended to mitigate the risk of bird–aircraft collisions (strikes). However, robust evidence linking …
Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin
Graduate Theses, Dissertations, and Problem Reports
Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …

Intertidal Habitat Utilization By Endangered Green Sturgeon (Acipenser Medirostris), Willapa Bay, Washington, Luke Stilwater
Intertidal Habitat Utilization By Endangered Green Sturgeon (Acipenser Medirostris), Willapa Bay, Washington, Luke Stilwater
All Master's Theses
This study looks at a portion of the designated critical habitat for the threatened southern distinct population segment of green sturgeon (Acipenser medirostris) in Willapa Bay, Washington. Willapa Bay is an intermediate size (258.7mi2) estuary on the southwest coast of Washington State, approximately 30 miles north from the mouth of the Columbia River. Recent studies completed by the National Marine Fisheries Service have shown that significant aggregations of green sturgeon in Willapa Bay occur during the late summer months, and foraging activity for burrowing ghost shrimp (Neotrypaea californiensis) is evidenced by small round feeding pits (30-60 cm diameter) in the …

Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
All Master's Theses
Beaver reintroduction programs are increasingly being viewed as a way to enhance salmonid habitat and production. However, the actual effectiveness of using beavers as a habitat enhancement tool for ESA listed steelhead Oncorhynchus mykiss populations is unknown. We examined the type of habitat, at both the microhabitat and mesohabitat levels, preferred by steelhead in three small streams in the upper Yakima Basin, WA through standard snorkel surveys and habitat measurements. Our results suggest that steelhead in small streams strongly prefer (relative to availability) microhabitats that have deeper water(> 30 cm), slow stream velocities(< 0 .05 mis), and complex cover types. Habitat partitioning among the size-classes (small< 50 mm, medium 50-90 mm, large> 90 mm total length, TL) principally operated …

Minimun Riparian Buffer Width For Maintaining Water Quality And Habitat Along Stevens Creek, Sammi Bray
Minimun Riparian Buffer Width For Maintaining Water Quality And Habitat Along Stevens Creek, Sammi Bray
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT Riparian buffer zones are important sites of biodiversity, sediment trapping, pollutant removal, and hydrologic regulation that have significant implications for both people and wildlife. Urbanization’s influence on and need for adequate water quality increases the need for careful planning in regards to riparian areas. Wildlife are key components in the ecosystem functions of riparian zones and require consideration in peri-urban planning as well. This study reviews relevant literature to determine the recommended minimum riparian buffer width for maintaining water quality and habitat along Stevens Creek in Lincoln, Nebraska. Only sources that listed a specific purpose related to water quality …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck
All Master's Theses
Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

A Study Of The Summer Steelhead, Oncorhynchus Mykiss In Several Intermittent Tributaries Of The Satus Creek Basin, Washington, Joel Denney Hubble
A Study Of The Summer Steelhead, Oncorhynchus Mykiss In Several Intermittent Tributaries Of The Satus Creek Basin, Washington, Joel Denney Hubble
All Master's Theses
The summer steelhead, Oncorhynchus mykiss population was studied in three intermittent tributaries in the Satus Creek Basin. There was a strong tendency for post emergent fry, resulting from redds located in intermittent reaches to move downstream. However, survival to perennial flow conditions was very low. Steelhead production in Dry Creek appears to be lower than in Logy Creek, because of elevated water temperatures and minimal spring and summer stream flow.
