The Birds And The Bees And The Willows: Understanding The Reproductive Biology Of Salix Nigra Marsh., Julianne Gmys Grady Jan 2023

The Birds And The Bees And The Willows: Understanding The Reproductive Biology Of Salix Nigra Marsh., Julianne Gmys Grady

Graduate Theses, Dissertations, and Problem Reports (ETD)

Salix nigra is a common tree-form willow found throughout the eastern United States and Canada in riparian and wetland habitats. Like other members of the Salicaceae, it is dioecious with separate male and female individuals. While Salix has been thought to be strictly insect pollinated and Populus wind pollinated, several species of Salix have had wind pollination present in varying amounts by species. S. nigra’s pollination syndrome has not been studied extensively, though it is assumed to be insect pollinated. Unlike other willows with wind pollination, S. nigra is basal on the Salix phylogenetic tree. This study was conducted …

Abundance-Habitat Relationships And Aquatic-Terrestrial Habitat Selection Patterns For Wood Turtles (Glyptemys Insculpta) In The Upper Midwest, Jena Marie Staggs Jan 2023

Abundance-Habitat Relationships And Aquatic-Terrestrial Habitat Selection Patterns For Wood Turtles (Glyptemys Insculpta) In The Upper Midwest, Jena Marie Staggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to range-wide population declines, wood turtles (Glyptemys insculpta) are under review for federal listing under the United States Endangered Species Act. Understanding how habitat associations and environmental conditions influence population dynamics and spatiotemporal activity patterns is fundamental for designing effective management strategies. Previous work on wood turtle abundance-habitat relationships focused on broad-scale habitat relationships in northeastern North America. However, regional differences in climate, habitat conditions, and land use patterns limit their applicability to much of the wood turtle’s Upper Midwest distribution. Much of our understanding of wood turtle activity patterns is based on radiotelemetry studies, which are biased towards …

Livestock Depredation By Leopards, Associated Economic Losses, And Financial Compensation To Communities In Chhota Udepur District Of Central Gujarat, India, Shalu Mesaria, Pratik Desai, Shruti Patel, Dhaval Gadhavi, Anthony J. Giordano, Nishith Dharaiya Jan 2023

Livestock Depredation By Leopards, Associated Economic Losses, And Financial Compensation To Communities In Chhota Udepur District Of Central Gujarat, India, Shalu Mesaria, Pratik Desai, Shruti Patel, Dhaval Gadhavi, Anthony J. Giordano, Nishith Dharaiya

Human–Wildlife Interactions

Livestock depredation by large carnivores has been documented across the entire Indian subcontinent. The failure of managers to mitigate livestock losses in landscapes dependent on subsistence agriculture poses a threat to the conservation of carnivores. For much of Gujarat, a western Indian state characterized by extensive semi-arid habitats, the Indian leopard (Panthera pardus fusca) is considered an apex predator. Increasing regional leopard populations in response to protection efforts has led to more attacks on humans, along with an increase in rates of livestock depredation. In many cases, the regional forest department financially compensates livestock owners for depredation caused …

A Critical Look At Wild Pig Elimination: Myths And Facts, Kim M. Pepin, Travis L. Guerrant, Jeremiah L. Psiropoulos, Jeanine T. Neskey, John M. Tomeček, Michael J. Bodenchuk, Janean L. Romines Jan 2023

A Critical Look At Wild Pig Elimination: Myths And Facts, Kim M. Pepin, Travis L. Guerrant, Jeremiah L. Psiropoulos, Jeanine T. Neskey, John M. Tomeček, Michael J. Bodenchuk, Janean L. Romines

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are abundant and widely distributed in the United States. They damage crops and pastures, predate livestock and sensitive species, impact ecosystem functions, and damage personal property. To address these issues, some states in the United States are seeking complete elimination. A frequently asked question by stakeholders is: “What portion of the population needs to be removed annually to reach elimination?” The number 70% is widely touted as the answer. There is little scientific evidence to support that this percent annual removal would be needed to achieve elimination, yet 70% has now become a standard …

Sea-Ice Conditions Predict Polar Bear Land Use Around Military Installations In Alaska, Eric V. Regehr, Kristin L. Laidre, Todd C. Atwood, Harry L. Stern, Benjamin Cohen Jan 2023

Sea-Ice Conditions Predict Polar Bear Land Use Around Military Installations In Alaska, Eric V. Regehr, Kristin L. Laidre, Todd C. Atwood, Harry L. Stern, Benjamin Cohen

Human–Wildlife Interactions

Polar bears (Ursus maritimus) are threatened by sea-ice loss due to climate change, which is concurrently opening the Arctic to natural resource extraction and a broader scope of national security responsibilities. Mitigating the risk of human–bear conflicts is an emerging challenge as many polar bears spend longer ice-free summers on land where they have limited access to food and come into more frequent contact with people. We investigated a suite of physical and ecological variables that influence the timing of polar bear arrival on, and departure from, land using remote-sensing data on sea-ice extent and satellite telemetry data …

Côté, Julie Cunningham, Adam Ford, Patti Happe, Chad P. Lehman, Kim Poole, Clifford G. Rice, Kirk Safford, Wesley Sarmento, Laura Wolf

Human–Wildlife Interactions

Interactions between humans and wildlife include a number of consumptive and non-consumptive forms. In some cases, the increased demand for wildlife viewing can precipitate new human–wildlife conflicts. Mountain goats (Oreamnos americanus; goats) are native to a number of North American mountain ranges from southeastern Alaska to southwestern Montana, USA. Goat habitat typically consists of steep terrain and cold weather habitats, which has left them particularly vulnerable to climate change. Their alpine environments also make them vulnerable to disturbance by aircraft and land-based motorized human activity. We reviewed and characterized situations in which goats in close proximity to humans …

Rat Biosecurity Surveillance And Response Following Eradication On A Tropical Atoll, David Ringler, Richard Griffiths, Frank Murphy, Baudouin Des Monstiers, James C. Russell Jan 2023

Rat Biosecurity Surveillance And Response Following Eradication On A Tropical Atoll, David Ringler, Richard Griffiths, Frank Murphy, Baudouin Des Monstiers, James C. Russell

Human–Wildlife Interactions

Biosecurity is a key element following any eradication operation, employing tools that allow both the identification and elimination of survivors or the early detection of new invaders. Eradication managers must ensure the surveillance strategy is correctly adapted to the spatial context and that the potential causes of a pest’s presence are understood to optimize their operational plans. We used the case of the eradication of black (Rattus rattus) and Pacific rats (Rattus exulans) from Honuea and Onetahi islets (Tetiaroa Atoll, French Polynesia) in 2020 to test an approach that combines rapid eradication assessment modelling and genetic …

Human Fatalities Resulting From Wild Pig Attacks Worldwide: 2000–2019, John J. Mayer, James E. Garabedian, John C. Kilgo Jan 2023

Human Fatalities Resulting From Wild Pig Attacks Worldwide: 2000–2019, John J. Mayer, James E. Garabedian, John C. Kilgo

Human–Wildlife Interactions

Although reported to be rare, human fatalities resulting from wild pig (Sus scrofa) attacks do occur. Toward a better understanding of patterns in fatal wild pig attacks, we synthesized worldwide reports of wild pig attacks on humans between 2000 and 2019. We documented 163 separate reports of fatal wild pig attacks that resulted in 172 human deaths. On average, 8.6 human deaths occurred annually due to wild pig attacks during those 2 decades. The majority of fatal attacks resulted in a single human death; however, there were 6 cases in which an individual fatal attack resulted in 2–4 …

Effectiveness Of Citizen Engagement In A State Agency Egg-Oiling Program To Reduce Urban Canada Goose Populations And Conflicts, Charles H. Cope, Tom F. Bidrowski, Jon P. Beckmann Jan 2023

Effectiveness Of Citizen Engagement In A State Agency Egg-Oiling Program To Reduce Urban Canada Goose Populations And Conflicts, Charles H. Cope, Tom F. Bidrowski, Jon P. Beckmann

Human–Wildlife Interactions

In many cases, urban environments create high-quality habitat for wildlife that may allow species to form commensal relationships with humans. Positive impacts of urban environments (e.g., high-quality nesting habitat) may enhance survival and/or increased fecundity. One species that has shown the ability to form commensal relationships with humans in urban environments is Canada geese (Branta canadensis). Canada goose populations have continued to rebound in Kansas, USA, and across the Great Plains, such that the estimated resident population in Wichita, Kansas, grew from 0 to >5,000 resident geese and the over-winter population increased from 1,600 in 1997 to >18,000 …

Human–Black Bear Interactions And Public Attitudinal Changes In An Urban Ordinance Zone, Mark A. Barrett, Sarah E. Barrett, David J. Telesco, Michael A. Orlando

Human–Wildlife Interactions

Human–bear (Ursus spp.) interactions (HBI) commonly occur in residential areas throughout North America. Negative HBI can be alleviated by using bear-resistant garbage cans (BRC) and by securing other bear attractants (e.g., bird feeders). Since the early 2000s, human and Florida black bear (U. americanus floridanus) densities have increased substantially throughout Florida, USA, concurrently producing an increase in HBI. In central Florida, an area with high densities of humans and black bears, we surveyed 2 neighborhoods that occurred in an urban ordinance zone established in 2016 that required residents to secure anthropogenic food sources. Residents were supplied with …

The Importance Of Highlighting Wildlife Conservation Success In Urban Areas, Jonathon D. Cepek Jan 2023

The Importance Of Highlighting Wildlife Conservation Success In Urban Areas, Jonathon D. Cepek

Human–Wildlife Interactions

Wildlife professionals in urban areas face many challenges balancing wildlife conservation and managing human–wildlife conflicts. The urban public is often more influenced by news and social media of wildlife than they are by firsthand experiences. The information they hear is typically about high-density urban species in conflict situations. Therefore, it is important to find ways to engage the public through these outlets about wildlife conservation. Recently, Cleveland Metroparks (Ohio, USA) highlighted the return of extirpated wildlife species through news and social media. This offered opportunities to capture media and public attention and share information about wildlife conservation, the value of …

The Lord Howe Island Rodent Eradication: Social And Technical Lessons For Inhabited Islands, Grant A. Harper, Simon Pahor, Kelly Harrington, Darcelle Matassoni, Darryl Birch

Human–Wildlife Interactions

The 2019 rodent eradication on 1,455-ha Lord Howe Island, Australia, was the second and largest attempted on a permanently inhabited island. With 445 residents, it presented numerous novel challenges, resulting in an operation best summarized in 4 words: compromise, commensal, complexity, and cost. A ground-based operation was conducted across the inhabited portion of the island, some 300 ha known as the “settlement,” with aerial bait applied on forested hill country and cliffs (1,200 ha). Initial community resistance and the presence of mice (Mus musculus) meant that almost 19,000 external bait stations were established within the settlement, on a …

An Automatic System To Evaluate Bait Station Visitation By Brown Treesnakes And Mongooses, Robert T. Sugihara, William C. Pitt, Are R. Berentsen, Francis L. Benevides Jr. Jan 2023

An Automatic System To Evaluate Bait Station Visitation By Brown Treesnakes And Mongooses, Robert T. Sugihara, William C. Pitt, Are R. Berentsen, Francis L. Benevides Jr.

Human–Wildlife Interactions

Understanding the temporal, spatial, and behavioral patterns of the free-ranging target species in response to candidate baits and baiting strategies is important to ensure control success. This information can also assist in the development and deployment of feeding stations and can exclude non-target species while constituting effective bait delivery and control strategies for certain invasive animals, especially at environmentally sensitive sites. We used passive integrated transponder (PIT) tags in conjunction with very-high frequency radio-telemetry to remotely record bait station visitations and evaluate bait attractiveness in separate field research studies of brown treesnakes (Boiga irregularis) on Andersen Air Force …

Raccoon Selection For Anthropogenic Resources Provides Challenges For Wildlife Management In Yosemite Valley, Erika L. Anderson, Sean M. Matthews, David S. Green, E. Binta Wold, Katie Patrick, Rachel Mazur Jan 2023

Raccoon Selection For Anthropogenic Resources Provides Challenges For Wildlife Management In Yosemite Valley, Erika L. Anderson, Sean M. Matthews, David S. Green, E. Binta Wold, Katie Patrick, Rachel Mazur

Human–Wildlife Interactions

Managing human–wildlife incidents dominates the attention and resources of many wildlife management programs. National parks in the United States have a long history with human–wildlife interactions and conflicts. Improvements in communication with visitors, food-storage infrastructure, regulation enforcement, and the management of habituated and food-conditioned animals have decreased human–wildlife conflicts. Yosemite National Park, California, USA, is well known for its history of human–bear (Ursus spp.) conflicts. However, in the Yosemite Valley portion of Yosemite National Park, conflicts with raccoons (Procyon lotor) now outnumber those with black bears (U. americanus). Like bears, raccoons pose a risk of …

Human–Alligator Incidents In The United States: Risky Human Behaviors Cause Most “Attacks”, Mark S. Teshera, Azar Kordbacheh, Frank J. Mazzotti

Human–Wildlife Interactions

Interactions between humans and American alligators (Alligator mississippiensis), often resulting in negative outcomes for both participants, have occurred for centuries in the United States. As both populations increased over time, contact and conflict with one another became inevitable. Although human–alligator conflicts have been well documented, there has been no detailed classification of risk factors associated with human activities immediately preceding, and in most cases precipitating, an encounter. Herein, we provide a ranking system to categorize different human activities, based on risk levels, immediately preceding an encounter with an alligator. To complete our review in 2021, we initially gleaned …

Under Ice Photosynthetic Primary Production And Dark Carbon Fixation In A Temperate Freshwater System, Vanessa Cubillos Tellez Jan 2023

Under Ice Photosynthetic Primary Production And Dark Carbon Fixation In A Temperate Freshwater System, Vanessa Cubillos Tellez

Dissertations, Master's Theses and Master's Reports

Ice-covered lakes are vulnerable to environmental change, especially those in the Northern Hemisphere where ice cover is rapidly declining due to global warming. These changes can alter metabolic processes and disrupt carbon cycling driven by primary producers who form the base of the food chain and are key to sustaining ecosystem function. Photosynthetic primary production and dark carbon fixation under the ice in the Keweenaw Waterway, a temperate freshwater system that is ice-covered for ~3 months out of the year, were studied using a carbon isotopic labeling (14C-bicarbonate) technique. Water samples were collected weekly during ice cover and monthly during …
