Relationships Between Stable Isotopes And Mercury Contaminants In Feathers Of Black-Tailed Gull Larus Crassirostris, Yasuaki Niizuma

Marine Ornithology

The feathers of seabirds are widely used as appropriate indicators for various aspects of avian ecology and toxicology. To reveal total mercury (Hg) concentrations and the connection to diet using stable isotope analysis in Black-tailed Gulls Larus crassirostris, feathers were collected from 10 carcasses from the breeding colony on Kabushima Island during the incubation period in 2020. Total Hg concentrations in primary remiges were found to decrease during the molt sequence. The innermost primaries (P1), the first to be replaced after breeding, had the highest Hg concentrations of all feathers (7.73 ± 2.37 μg/g dry weight). The concentration of Hg …

Seasonal And Spatial Patterns Of Avian Assemblages In The Eastern Taiwan Strait: Implications For Offshore Wind Farm Development, Mei-Ling Bai, Chia-Hsiang Huang, Yu-Yi Lien

Marine Ornithology

The eastern Taiwan Strait, a region situated along the East Asian-Australasian Flyway and currently undergoing rapid offshore wind energy development, remains poorly studied with respect to its seabird assemblages. Through intensive vessel-based transect surveys conducted between 2014 and 2021, this study documented 22,187 birds from 105 species across 10 orders and 29 families. Migratory non-seabirds accounted for 55.2% of individuals and dominated the species richness, highlighting the region's importance for migratory pathways. Seabird density was relatively low, however, consistent with trends in other tropical regions, and this pattern may also reflect both environmental degradation and methodological differences in density estimation. …

Valle, Andrea Maranho, Mariana K. Britto, Hugo Gallo, André S. Barreto

Marine Ornithology

We compiled data on seabirds that use coastal and coastal/oceanic habitats, recorded alive and dead, during four years of beach monitoring in Santa Catarina, Paraná, and São Paulo states, along Brazil's south and southeast coast. This is a pioneering study, as no previous studies of this magnitude have been done in Brazil. Among the 26,900 individuals collected, 45 species were identified, distributed across four orders: Charadriiformes (29 species), Pelecaniformes (12 species), Sphenisciformes (one species), and Suliformes (three species). We determined maturity and sex for the five most abundant species: Magellanic Penguin Spheniscus magellanicus, Kelp Gull Larus dominicanus, Brown Booby Sula …

Quantifying The Effect Of Time On Geolocation Accuracy In Seabirds, Sophie Bennett, Richard A. Phillips, Jonathan A. Green

Marine Ornithology

Light-based geolocation can be an effective tool for understanding movements and distributions of free-ranging seabirds, particularly during migrations and long-distance foraging trips. The light levels recorded by geolocators (global location sensors; GLS loggers) are used to infer latitude and longitude of individuals from day length and time of local midday relative to UTC (Coordinated Universal Time), respectively. However, there is an associated inaccuracy in these location estimates, associated with both systematic and random error. Previous studies have quantified this error by calculating distances to locations over the same time period derived from more accurate devices such as satellite transmitters (platform …

Behavioral Response Of Atlantic Puffins Fratercula Arctica To Marine Heatwaves In The Gulf Of Maine, Usa: A Webcam Study, Julie Wallace, Keenan Yakola, Stephen W. Kress, Donald E. Lyons

Marine Ornithology

We observed a family of Atlantic Puffins Fratercula arctica in a burrow on Seal Island National Wildlife Refuge in the Gulf of Maine, USA, during the 2017-2020 and 2022 breeding seasons. The burrow was equipped with a high-resolution web camera, which allowed 24-hour daily observations. We investigated the impacts of elevated sea surface temperature (SST) and marine heatwaves (MHWs), which are linked to low food availability, on chick provisioning and burrow attendance. In 2017, 2019, 2020, and 2022, the female was the primary provisioner, providing twice as many feedings as the male, and the male was the primary burrow guardian, …

Differing Sex-Related Arrival Of Red Phalaropes Phalaropus Fulicarius At Wintering Grounds In Chile, Yerko A. Vilina, Valeria Sabaj, Paola Sáez, Daniela Leiva-Calderón, Franco Cruz-Jofré

Marine Ornithology

Information is often sparse about whether sex affects arrival of long-distance migratory species at wintering grounds. In this paper we analyze the Red Phalarope Phalaropus fulicarius, a species exhibiting sex-role reversal in its nesting patterns. Between September and December 2005, 166 individuals were found dead along the northern Chile coast, which borders the Humboldt Current. Each individual was tagged, and the date of finding was recorded. Nuclear DNA samples were obtained from 46 individuals and analyzed using a molecular sexing method. Results indicate that females arrived between September and early October, with males appearing in late October. On average, females …

Early Records Of Stones (Gastroliths) In Stomachs Of Antarctic Penguins, Peter D. Shaughnessy

Marine Ornithology

During 1915/16, A. H. Ninnis, on board S/Y Aurora of Shackleton's Imperial Trans-Antarctic Expedition of 1914-1917, collected penguins and seals to augment food supplies while the ship drifted in pack ice. Ninnis found stones (gastroliths) in 86 of 166 Adelie Penguin Pygoscelis adeliae stomachs (52%); numbers varied from 0 to 38 and averaged 2.1 per bird. He also examined eight Emperor Penguin Aptenodytes forsteri stomachs. Two birds had about a dozen stones each, three had some, and three had none. The function of stones in penguins' stomachs remains unknown, but Ninnis did not consider them essential for digestion.

Molecular Screening Of Avian Viruses And Parasites In Wedge-Tailed Shearwaters Ardenna Pacifica And Barau’S Petrels Pterodroma Baraui On Réunion Island, Camille Lebarbenchon, Celine Toty, Solenn Boucher, Audrey Jaeger, Matthieu Le Corre

Marine Ornithology

We investigated Wedge-tailed Shearwater Ardenna pacifica and Barau's Petrel Pterodroma baraui exposure to infectious agents circulating in the western Indian Ocean. Using polymerase chain reaction and serological analyses, we screened for influenza viruses, flaviviruses, coronaviruses, and blood parasites (Haemoproteus, Leucocytozoon, and Plasmodium). No active infections were detected and serological results suggested limited past exposure, with only two Wedge-tailed Shearwaters testing positive for antibodies to the influenza A virus. These findings indicate the limited role of these species as epidemiological reservoirs. However, environmental factors such as tick infestations and isolated breeding habitats highlight the need for continued epidemiological monitoring to support …

What To Eat When Far From Home? A Vagrant Seabird Selects Novel But Analogous Prey, William L. Kennerley, Gemma V. Clucas, Donald E. Lyons, Keenan C. Yakola

Marine Ornithology

Vagrancy in birds is an important mechanism contributing to range expansion and the establishment of new breeding populations. However, research on the ecology of vagrant individuals has been limited. From 2005 to 2021, a Red-billed Tropicbird Phaethon aethereus, far outside its usual range, was a summer resident at Seal Island, Maine, USA. In 2020 and 2021, we collected fecal samples from this individual and identified prey types consumed via DNA metabarcoding techniques, using 12S and 18S genes. We identified six fish species in the Red-billed Tropicbird fecal DNA samples, with Atlantic Saury Scomberesox saurus and Atlantic Mackerel Scomber scombrus contributing …

Breeding Phenology And Reproductive Success Of Larid Species Nesting In Cuba, Antonio Garcia-Quintas, Dennis Denis, Christophe Barbraud, Sophie Lanco

Marine Ornithology

Breeding phenology is a life history trait that influences reproductive success and population dynamics, yet it remains poorly studied in tropical seabird species. The Caribbean constitutes a breeding hotspot for seabirds, although information about their phenology and reproductive success is limited. We characterized the breeding phenology and reproductive success of seven larid species during the 2021 breeding season on three cays in Cuba. To document breeding phenological phases, we conducted weekly surveys and used camera traps. We also recorded the number of nests, eggs and fledglings. Overall, the breeding phenology of the studied species was seasonal and relatively synchronous, occurring …

Bonavista Bay Murre Hunters In Newfoundland And Labrador Propose Further Interaction With Biologists And Managers, C. Wayne Humphries, Grant R. W. Humphries, Alexandra M. C. Robbins, Gail S. Fraser

Marine Ornithology

Thick-billed Murres Uria lomvia and Common Murres U. aalge, seabirds with low reproductive rates, delayed reproduction, and high adult survivorship, are hunted in Newfoundland and Labrador (NL) by non-Indigenous residents. The traditional hunt has a complex regulatory history as a result of NL joining Canada in 1949 and the protection of non-game species under the Migratory Bird Convention Act. Thirty hunters from the northeastern region of the island of Newfoundland were interviewed about their knowledge of murres, their hunting practices, and their opinions on current hunting regulations. While the hunters had detailed local species knowledge from the region they hunted, …

Pathways And Challenges In The Clinical Translational Of Radiopharmaceuticals For Pediatric Investigations, Erik Stauff, Hanieh Karimi, Heidi H. Kecskemethy, Thomas H. Shaffer, Reza Vali, Lauren W. Averill, Xuyi Yue

Department of Radiology Faculty Papers

Radiopharmaceutical development and clinical translation face numerous scientific, ethical, and regulatory challenges, particularly within the pediatric population. Although molecular imaging holds significant promise for improving diagnosis and treatment across a spectrum of diseases, including pediatric-specific conditions like Kawasaki disease, autism spectrum disorders, attention-deficit/hyperactivity disorder, and neuroblastoma, the path from discovery to clinical application remains problematic. The U.S. Food and Drug Administration (FDA) provides three primary pathways-traditional Investigational New Drug (IND) applications, exploratory Investigational New Drug application (eIND), and the Radioactive Drug Research Committee (RDRC) mechanism-to facilitate clinical translation of radiotracers. However, these frameworks are not specifically tailored to pediatric needs. …

Neural Dynamics In The Cortico-Basal Ganglia-Thalamic-Cortical Loop Underlying Flexible Motor Timing, Zidan Yang

Electronic Theses and Dissertations 2020 - Present

The ability to flexibly time actions is a fundamental aspect of voluntary motor control. The frontal cortex and striatum exhibit ramping neural activity that predicts movement initiation, suggesting they function as a core timing circuit. However, the distinct computational roles of these highly interconnected regions and the specific cell types involved have remained elusive. This thesis investigates the neural mechanisms of motor timing by combining cell-type-specific perturbations, multi-regional electrophysiology, and computational modeling in mice. First, we demonstrate that the frontal cortex and striatum play complementary roles in an adjustable timing mechanism. Transiently silencing the frontal cortex effectively “pauses” the ramping …

Combined with a high surface-to-volume ratio and tunable and chemically versatile surfaces, these support broad applications across catalysis, electronics, and life sciences. Moreover, the biocompatible characteristics of NDs enable their controllable interfacial interactions with biological systems, positioning them as excellent candidates for advancing cutting-edge biomedical sciences, particularly through the engineering of efficient material biointerfaces that facilitate optimal interactions with …

Lobizona And Cemetery Boys: Broadening Representation Of The Latinx/Chicanx Community, Genesis Pabon

Electronic Theses and Dissertations 2020 - Present

This thesis focuses on two young adult speculative fiction novels, Lobizona and Cemetery Boys, that showcase the need for accurate representation of the Latinx/Chicanx and LGBTQ+ communities. Themes of sexuality, race, identity, and the gender binary within Latinx/Chicanx cultures will be explored. The narratives of the protagonists in both novels disrupt the gender binary in the United States and the Latinx/Chicanx community. There is a lack of literature that focuses on Latinx/Chicanx young adult speculative fiction, particularly in the United States, highlighting the need for more scholarly research in this area. It is essential for literary scholars and readers to …
