Lycosidae Abundance And Diversity Across Lawn And Leaf Litter Substrate, Sage O. Lockett, Dan Albrecht-Mallinger
Undergraduate Research Posters
Significant knowledge gaps exist in how land-cover impacts ground-hunting spider populations. To fill these gaps, this study investigates a common family of ground-hunting spiders, Lycosidae, to determine differences in their abundance and diversity in deciduous leaf litter and managed turfgrass (lawn). The study was conducted within a forested ecosystem at Virginia Commonwealth University's Rice Rivers Center in Charles City County, Virginia. I placed 10 belt transects (1m x 20m) on lawn substrate and 10 identical transects in deciduous forest leaf litter substrate. I performed repeated visual census via eyeshine and manual capture of up to three individuals per transect …
Towards Understanding The Interactions Between Ospreys And Human-Made Structures In The Tennessee River Valley, Natasha Karina Murphy
Towards Understanding The Interactions Between Ospreys And Human-Made Structures In The Tennessee River Valley, Natasha Karina Murphy
Theses and Dissertations
Raptor nests on human-built structures represent a significant source of conflict as they can result in bird mortality, fires, structure damage, service distribution, or power outages when falling nest materials or animals connect with energized conductors. Power companies, such as the Tennessee Valley Authority (TVA), wish to mitigate these conflicts to avoid service disruptions. In this dissertation, I present my work towards understanding and mitigating the interactions between Ospreys (Pandion haliaetus) and human-made structures. To achieve this, I explored multiple elements of conflict identification, monitoring, and basic ecology of the target species to better inform conflict mitigation. In Chapter I, …

Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour. Using biologgers, we tagged 62 post-moult Weddell seals in McMurdo Sound and vicinity between 2010 and 2012. Generalized additive mixed models were used to (i) explain and predict the probability of seal presence and foraging behaviour from eight environmental variables, and (ii) examine foraging behaviour in relation to dive metrics. Foraging probability was highest in winter and lowest in summer, and foraging occurred mostly in …
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 …
Amphibian Occupancy And Diversity On A Post-Mined Landscape, Emma M. Buckardt
Amphibian Occupancy And Diversity On A Post-Mined Landscape, Emma M. Buckardt
Electronic Theses & Dissertations
Amphibian populations are declining globally, with habitat loss and fragmentation being a leading cause for their decline. Anthropogenic changes to a landscape, such as urbanization, agriculture, and surface mining, leave few native habitats intact, which can influence amphibian populations and communities to varying degrees. Amphibians can provide insight into the health of ecosystems because they are sensitive to changes in their environment. Thus, they can be considered indicator species in anthropogenically altered wetlands. The goal of this study was to characterize amphibian communities that are using surface mined lands that have undergone vegetative succession. For Chapter I, we used call …
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
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 …
Roslyn Meadows Wetland: Health, Development, And Importance To Humans And The Environment, Margaret Menso
Roslyn Meadows Wetland: Health, Development, And Importance To Humans And The Environment, Margaret Menso
Antonian Scholars Honors Program
Wetlands must be protected because of their importance for everyday life. Wetlands mitigate floods, acquire and store greenhouse gases, and support recreation. To protect wetlands, community members must understand their importance and advocate for their health. A website was designed to inform community members of the history, health, and benefits of the Roslyn Meadows wetland, including descriptions of the town history, development plans, and wetland health. A wetland health evaluation program assessment (WHEP), performed in 2020, indicated the Typha marsh contained in the development to be in excellent health.

Journal of Bioresource Management
We conducted this study to identify the preferred habitat of Atelerix algirus in the National Park of El Kala (PNEK), through the analysis of the catches rates of the species combined to an ethno zoological survey carried out among the residents. The study was conducted between January 2010 and December 2011, in five localities of the Park, different by their useful areas (forests and agricultural land) and their degree of urbanization: Raml Souk, El Aioun, Berrihane, El Kala and Bougous. We also surveyed 57 residents of Berrihane locality. Our results identified the locality of Berrihane as the preferred area of …
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Proceedings of the North American Crane Workshop
Vigilance plays an important role in the detection of possible threats and reducing the risk of predation, including during the incubation period. We examined the visual vigilance of incubating whooping cranes (Grus americana) in Juneau County, Wisconsin, during the 2019 nesting season. We deployed 9 trail cameras and tagged crane presence and behavior in 32,801 photos which were used in our analysis. We assessed individual nest and environmental variables and their effects on vigilant behavior of incubating cranes using linear mixed-models. Vigilant behavior was defined by a posture in which the crane’s head was up, neck was erect, …
Low-Head Dam Removal Increases Functional Diversity Of Stream Fish Assemblages, Adam Christopher Jones
Low-Head Dam Removal Increases Functional Diversity Of Stream Fish Assemblages, Adam Christopher Jones
Masters Theses
Despite the growing number of dam removals to date, very few have been studied to understand their impacts on stream fish communities. Despite being the most common type of dam in the U.S., an even smaller proportion of studies focus on the impacts of low-head dam removals, instead, focusing on the impacts of removal of larger dams. In this study, two previously impounded Illinois rivers were monitored to assess the impacts of low-head dam removal on the functional assemblage of stream fishes. This was accomplished by aggregating fishes into habitat and reproductive guilds, relating community changes to habitat, environmental metrics, …
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe,, Anne E. Lacy
Proceedings of the North American Crane Workshop
Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae) to varying degrees. However, little research has examined the relationship between habitat characteristics and stopover stay length in cranes. Site quality may relate to stay length with longer stays that allow individuals to improve body condition, or with shorter stays because of increased foraging efficiency. We examined this …

Vignette 15: Eelgrass Variations Ties To Sea Level Variations, Ronald Thom
Institute Publications
This vignette shares an overview of the process and results of a long-term eelgrass monitoring effort at the mouth of Sequim Bay. Coupling these local long-term findings with research and monitoring across the Salish Sea and the globe will help better understand the longer-term effects of global warming and perhaps other human and natural-derived pressures on coastal ecosystems, and provide clues on how to make these systems more resilient to pressures.

European green crab pose documented threats to cultured and wild shellfish, eelgrass, and shoreline habitats and ecosystems. Because they can prey on juvenile crabs and shellfish, dense populations of EGC in the Salish Sea region could put fisheries and aquaculture resources in peril. After Fisheries and Oceans Canada researchers reported an established EGC population in Sooke Basin, BC in 2012, the Washington Department of Fish and Wildlife (WDFW) worked with Washington Sea Grant (WSG) to secure Puget Sound Marine and Nearshore Grant Program funding and establish a volunteer-based early detection and monitoring program. WSG launched Crab Team in 2015 with …
Evaluating Avian Occupancy On Sites Treated With Nrcs Conservation Practices Implemented To Benefit Cerulean (Setophaga Cerulea) And Golden-Winged Warblers (Vermivora Chrysoptera) In West Virginia, Lincoln R. Oliver
Graduate Theses, Dissertations, and Problem Reports
The USDA - Natural Resources Conservation Service (NRCS) supports private lands conservation across the United States to benefit imperiled focal wildlife species using conservation practices to restore habitat. Through the Cerulean Warbler (Setophaga cerulea) Forestland Enhancement Project (CWAFEP) and the Working Lands for Wildlife (WLFW) Golden-winged Warbler (Vermivora chrysoptera) initiative, the NRCS provides technical and financial assistance to private landowners to implement conservation practices that follow science-based habitat management guidelines. Few research studies have evaluated focal species-specific occupancy on CWAFEP and/or WLFW sites, and research is required to inform each conservation project’s effectiveness in an adaptive …
Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
Habitat Selection And Host Detection In The Salamander Mussel, Simpsonaias Ambigua, Eric A. Stegmann
MSU Graduate Theses
The native freshwater mussels, Order Unionida, have suffered many species extinctions and loss of abundance. Two important threats to native mussels are loss of habitat and loss of access to the vertebrate hosts of the parasitic mussel larvae. The Salamander mussel, Simpsonaias ambigua, is a habitat specialist, living under flat rocks. It is often found in direct association with its only known host, the common mudpuppy, Necturus maculosus. This association could result from movement and habitat selection by the mussels themselves. Alternatively, it might result from the deposition of juveniles by a resident host. Habitat selection and host …
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 …

Range Extension For Dekay’S Brownsnake (Storeria Dekayi) In South-Central Nebraska, Macy K. Cool, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Dekay’s Brownsnake (Storeria dekayi) generally occurs in southeastern parts of the state, where the species was known from 16 counties. Herein, we update the distribution of S. dekayi in the state and briefly comment on habitat and abundance from observations in September and October 2018. We documented 7 new county records that extend its distribution in south-central Nebraska. We observed that S. dekayi does not only reside in mesic wooded habitats in Nebraska but also occupies open environments, including areas with upland grasslands and row-crop agriculture. Dekay’s Brownsnake currently is listed as a species of concern …
Snowshoe Hare (Lepus Americanus) Abundance In Relation To Habitat And Predator Assemblage Across The Apostle Islands, Jarod Reibel
Snowshoe Hare (Lepus Americanus) Abundance In Relation To Habitat And Predator Assemblage Across The Apostle Islands, Jarod Reibel
Masters Theses
Snowshoe hares (Lepus americanus) are a climate sensitive species that have a southern range boundary moving northward. Snowshoe hares are found on the Apostle Islands, Wisconsin which are near their southern boundary and differ by island in vegetative and carnivore communities. The archipelago serves as a natural laboratory to assess how top-down and bottomup forces interact and impact snowshoe hare populations. The objectives of this study were to determine the influence of vegetative characteristics, specifically visual obstruction, and the presence of predators on snowshoe hare abundances across the Apostle Islands. We conducted fecal pellet surveys to estimate hare abundance, measured …

Leptodactylus guianensis is reported for the first time for Colombia along with a distributional map of the species. The species is the fifth species of the L. latransspecies group documented in the country. Males possess a single, conical and slightly chisel-shaped thumb spine; only three species in the group have a single thumb spine. In collections, specimens of L. guianensis are misidentified as L. macrosternum, L. latrans or L. bolivianus. We provide morphological, colouration and habitat descriptions for where the species occurs in Colombia.
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Senior Projects Spring 2019
Many avian species overwinter in eastern North America; however, studies on bird populations are rarely undertaken during this critical survival time, and little is known as to their habitat preferences and foraging behavior. In this observational study, we performed a survey of birds overwintering in the Hudson Valley’s temperate, primarily-deciduous forests, assessing avian populations’ habitat preferences through the vegetative structural variables surrounding overwintering birds as they forage. Our results suggest that high canopy cover is critically important to predicting overwintering bird occupancy on a microhabitat scale. Moreover, overwintering birds preferentially occupy forest plots not dominated by sugar maples, in spite …
Autumn Roost Selection By Male Hoary Bats (Lasiurus Cinereus) In Northern California, Danielle (Skye) Salganek
Autumn Roost Selection By Male Hoary Bats (Lasiurus Cinereus) In Northern California, Danielle (Skye) Salganek
Cal Poly Humboldt theses and projects
The hoary bat, Lasiurus cinereus, is a solitary bat that roosts in the foliage of trees throughout the western hemisphere. Roosts are subject to the ambient temperature of their surroundings, thus hoary bats undergo long-distance migrations between summer and winter ranges to avoid freezing temperatures. Habitat selection has been studied during the summer for maternal female hoary bats, but not during migration and winter. Autumn migration coincides with the hoary bat mating period and it has been proposed that male and female bats may rendezvous on migration paths. Individuals may select roosts in stopover locations that enhance fitness by providing …
Influence Of Environmental Features On Spermatophore Placement In Spotted Salamanders (Ambystoma Maculatum), Megan A. Kuechle
Influence Of Environmental Features On Spermatophore Placement In Spotted Salamanders (Ambystoma Maculatum), Megan A. Kuechle
Theses and Dissertations
Successful reproduction in salamanders is driven by behavioral, environmental, and temporal interactions among adults. While much of our understanding of salamander mating systems is based upon either courtship behavior of both sexes or aspects of female choice, the decisions made by males regarding where to place spermatophores is much less quantified. In this study, we mapped male spermatophore placement in the spotted salamander (Ambystoma maculatum) with respect to ecological and spatial locations within a vernal pool complex in Charles City County, Virginia. The overall goal was to use the spatial and ecological placement of spermatophores to determine if …
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 …
Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead
Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead
Graduate Theses and Dissertations
It has been shown that bird communities are affected by the species composition and physical structure of plant communities. Within avian communities, the bird species that are the most localized in distribution tend to be the most affected by habitat changes. My research analyzed plant and bird communities found with the Painted Bunting (Passerina ciris Linnaeus), a locally common but declining species throughout much of its range. First, I describe vegetation characteristics associated with singing male Painted Buntings in northwest Arkansas. I categorized field sites with singing male Painted Buntings as either managed for wildlife or unmanaged, based on land-use …

The Pacific Salmon Explorer: A Data Driven Look At Salmon Populations And Their Habitats, Katrina Connors, Eileen Jones, Leah Honka, Katy Kellock, Eric Hertz, Brian E. Riddell
Salish Sea Ecosystem Conference
The lack of a centralized, standardized, and easily accessible repository of information on the state of natural resources, and threats to them, can undermine efforts to make informed, transparent, and evidenced-based management and conservation decisions. This is the case with Pacific salmon in British Columbia (BC), where a lack of information on the current status of salmon population and their habitats is undermining public confidence in the ability of government agencies to sustainability manage Pacific salmon populations. In an effort to provide broader public access to salmon datasets, the Pacific Salmon Foundation embarked on a major initiative to synthesize the …

Bull Kelp Bed Surveys In Island County, Washington Usa, Linda Rhodes, Vernon W. Brisley, Gregg Ridder, Debra Paros, Paulette Brunner, Barbara Brock, Barbara Bennett, Anna Toledo
Salish Sea Ecosystem Conference
Although bull kelp (Nereocystis luetkeana) is a prevalent nearshore habitat throughout the Salish Sea, its distribution and seasonal bed area dynamics are poorly characterized. Island County contains bull kelp beds that are positioned in dramatically different oceanographic situations. The western part of the County is fully exposed to marine conditions of the Strait of Juan de Fuca and Admiralty Inlet, while the eastern part is exposed to the strong freshwater influence of the largest rivers in Puget Sound. Each part contains bull kelp beds, providing an opportunity to compare their seasonal dynamics. Since 2015, the Island County Marine Resources Committee …
