Effects Of Invasive Wild Pigs And Supplemental Feeding On Wildlife In The Piedmont Region Of South Carolina, Elizabeth A. Saldo May 2022

Effects Of Invasive Wild Pigs And Supplemental Feeding On Wildlife In The Piedmont Region Of South Carolina, Elizabeth A. Saldo

All Theses

Wild pigs (Sus scrofa), which are invasive in much of the world, can alter ecosystems and compete with native species through interference competition and resource exploitation. We assessed the potential for interspecific interactions between invasive wild pigs and other wildlife in the Piedmont region of South Carolina by examining their spatiotemporal overlap in a correlational field study and an experimental field study. Our correlational study used data from wildlife cameras in seasonal occupancy, N-mixture, and temporal overlap analyses. Both deer (Odocoileus virginianus) and coyote (Canis latrans) site use were negatively associated with wild pig …

Advancing Hymenocallis Coronaria Conservation And Restoration For Improved Habitat Management In Fall Line Streams Of The Southeast, Andrew Paul Grunwald May 2022

Advancing Hymenocallis Coronaria Conservation And Restoration For Improved Habitat Management In Fall Line Streams Of The Southeast, Andrew Paul Grunwald

All Theses

The rocky shoals spider lily (Hymenocallis coronaria) is a culturally and ecologically important emergent macrophyte endemic to the biodiverse shoals of fall line streams in the southeastern United States. H. coronaria has declined throughout its range as shoal habitat has become increasingly threatened by flow modification and other anthropogenic stressors. The genetics and botany of H. coronaria have been given considerable attention, but quantitative habitat research has been lacking. Furthermore, despite substantial need, public interest, and its status as an indicator species for fall line streams, no research has been conducted on H. coronaria restoration. Our main objectives …

The Plight Of The Enigmatic Southern Resident Killer Whales: Have We Done All We Can To Recover These Icons Of The Salish Sea?, Orla Robinson, Regan Nelson, Dr. Lance Barrett-Lennard, Carleen Thomas

Salish Sea Ecosystem Conference

Southern Resident killer whales recognize no boundaries but frequent the coastal waters of southern British Columbia (Canada) and northern Washington State (USA). Having acknowledged their conservation plight, the two respective national governments have afforded this distinct and much-valued population the status of ‘Endangered’ under their respective endangered species laws. Divergent natural resource management regimes, endangered species legislation, and marine use profiles in the two nations have at times limited a concerted conservation push for these killer whales. However, much has been learned over the past 20 years about the three primary threats to their recovery - diminished prey (primarily Chinook …

Spatial And Temporal Patterns Of Biofouling Aquatic Invasive Species In The Salish Sea, Katie Sp Gale, Brett R. Howard, Calley Wasser, Thomas W. Therriault

Salish Sea Ecosystem Conference

Aquatic invasive species (AIS) have the potential to result in significant ecological and economic impacts. In the Salish Sea a number of primary and secondary invasion vectors exist including commercial shipping, recreational boating, and aquaculture-related movements that can introduce or spread AIS. An important subset of all AIS in this area are biofouling species, including tunicates and bryozoans, that can outcompete and displace native species. To better understand spatial and temporal patterns of biofouling AIS in the Salish Sea, Fisheries and Oceans Canada (DFO) has carried out a monitoring program since 2006 – a program that has expanded in scope …

Howe Sound/Átl’Ḵa7tsem Marine Stewardship Initiative: A Bottom-Up And Community Based Approach To Marine Spatial Planning In The Salish Sea, Bridget John, Nikita Wallia

Salish Sea Ecosystem Conference

Life in the ocean faces myriad anthropogenic pressures that vary in their spatial scales, from global climate change to site-specific industrial projects. Marine spatial planning (MSP) is one approach to manage these pressures while protecting ocean health and human access. Unfortunately, many coastal communities have restricted capacity to lead MSP processes due to two barriers: limited access to high resolution local data, and insufficient knowledge sharing across jurisdictions. Our project seeks to address these barriers by implementing a bottom-up approach to MSP in the Salish Sea, Canada. The Howe Sound/Átl’?a7tsem Marine Stewardship Initiative’s goal is to protect the diverse human …
