Tasmanian Records Of Vagrant Penguins, 1991–2025., Eric J. Woehler
Tasmanian Records Of Vagrant Penguins, 1991–2025., Eric J. Woehler
Marine Ornithology
During the period 01 January 1991 to 31 August 2025, there were 274 records of vagrant penguins in Tasmania. These records represented three genera: Aptenodytes, Pygoscelis, and Eudyptes. The most frequently reported species were Fiordland Penguin E. pachyrhynchus, Royal Penguin E. schlegeli, and King Penguin A. patagonicus. High numbers of records were reported from 10 years, with a peak in 1999 and a lower peak in 2023. Records from January to March accounted for approximately 42% of all vagrant penguin occurrences and corresponded with the arrival of pre-moult birds of all ages. A range …
Evidence For Colony Attendance By Immature Streaked Shearwaters Calonectris Leucomelas During The Chick-Rearing Period., Helen M. Pružina, Akiko Shoji, Masaki Shirai, Sakiko Matsumoto, Ken Yoda, Annette L. Fayet
Evidence For Colony Attendance By Immature Streaked Shearwaters Calonectris Leucomelas During The Chick-Rearing Period., Helen M. Pružina, Akiko Shoji, Masaki Shirai, Sakiko Matsumoto, Ken Yoda, Annette L. Fayet
Marine Ornithology
Many seabird species have a long breeding-deferral period, during which individuals mature and spend most of their time at sea, making them particularly difficult to study. In some species, immatures are known to start visiting colonies before reaching adulthood, presumably to learn the behaviours required to secure a nest and mate for future breeding. However, immature colony attendance remains undocumented in many species, particularly those that are difficult to observe, such as nocturnal, cavity-nesting species and species in which immatures are indistinguishable from adults. Here, we studied the attendance patterns and behaviour of Streaked Shearwaters Calonectris leucomelas on Awashima Island, …

Satellite Tracking Of Galapagos Petrel Pterodroma Phaeopygia Reveals Distribution And Movements During Chick Rearing., Carolina B. Proaño, Sebastian M. Cruz, Josh Adams, Martin Wikelski
Marine Ornithology
We tracked 19 adult Galapagos Petrels Pterodroma phaeopygia during the chick-rearing seasons in 2009 and 2010 (Santa Cruz Island [n = 16] and Floreana Island [n = 3]) in the Galápagos Islands, Ecuador. Eight petrels performed 27 complete foraging trips lasting 0.6 to 18.8 days. Short trips (3.2 ± 2.1 days; 785 km; max displacement 671 km) and long trips (10.8 ± 3.9 days; 2,856 km; max displacement 1,034 km) resulted in concentrated use of waters off southern and western Isabela Island and within the Galápagos Marine Reserve (GMR). Less concentrated time extended farther southwest and eastward, in …
Unfamiliar Plumage Aberration Observed On A Razorbill Alca Torda At Machias Seal Island., Daniel Oliker, Antony W. Diamond, Heather L. Major
Unfamiliar Plumage Aberration Observed On A Razorbill Alca Torda At Machias Seal Island., Daniel Oliker, Antony W. Diamond, Heather L. Major
Marine Ornithology
Aberrant plumage variation in seabirds can be caused by both heritable genetic mutations and non-heritable somatic mutations due to environmental stressors. In Razorbills Alca torda, aberrant colouration has been documented four times: three as cases of melanism and one seemingly of leucism, both heritable mutations. Here, we describe the observation and subsequent capture of a Razorbill with an unfamiliar plumage phenotype we hypothesize to be caused by a somatic mutation. To our knowledge, this is the first reported instance of a somatic mutation affecting the plumage of a Razorbill in the primary literature.

Seasonal Variation In Trophic Niche And Resource Use In Great Black-Backed Gulls Larus Marinus., Samuel Langlois Lopez, Nina J. O’Hanlon, Jared Wilson, Rona A. R. Mcgill, Francis Daunt, Elizabeth A. Masden
Marine Ornithology
Seabirds experience variable extrinsic and intrinsic pressures throughout the annual cycle that affect their ability to forage. Consequently, their foraging strategies may vary between breeding and non-breeding seasons due to the constraints of central-place foraging during the former. Here, we studied a population of a generalist seabird, the Great Black-backed Gull Larus marinus, breeding at a colony on the Isle of May, Scotland. We quantified seasonal variation in sexual segregation, trophic position, trophic niche width, and resource use by examining stable isotopes in feathers collected from adults. We found no sexual segregation, but we detected population- and individual-level shifts …
Assessing The Impact Of Coordinated Mink Culling On Bird Populations On Coastal Islands In Norway., Fredrik R. Staven, Torgeir Nygård
Assessing The Impact Of Coordinated Mink Culling On Bird Populations On Coastal Islands In Norway., Fredrik R. Staven, Torgeir Nygård
Marine Ornithology
The introduction of the non-native American Mink Neogale vison (syn. Neovison vison), a predator of birds and their chicks and eggs, is one of many anthropogenic factors that may be driving the decline of seabird populations in areas where mink are prevalent. Previous studies have shown that ground-nesting birds utilising coastal ecosystems are especially vulnerable. In this study, we investigated changes in seabird and coastal-bound bird populations, focusing on ground-nesting species, and the potential effect from mink culling. Ten locations in the archipelago of Flatanger, a coastal municipality in central Norway, were surveyed, and bird counts from 1991, 2016, …

Dissecting Tumor Evolution And Immune Composition In Prc2 Loss (H3k27me3 Loss) Vs Retained Mpnst, Kuangying Yang
Dissecting Tumor Evolution And Immune Composition In Prc2 Loss (H3k27me3 Loss) Vs Retained Mpnst, Kuangying Yang
Arts & Sciences Graduate Student Theses and Dissertations
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas that arise sporadically or in the setting of neurofibromatosis type 1 (NF1). Although benign plexiform neurofibromas (PNs) are common in NF1, only a subset undergo malignant transformation, and the molecular events that define high-risk progression remain incompletely understood. A major axis of biological heterogeneity in MPNST is loss of Polycomb Repressive Complex 2 (PRC2), commonly detected through loss of H3K27me3 and frequently mediated by alterations in SUZ12 or EED. This dissertation integrates three manuscript-based studies to define genomic resources, tumor-intrinsic vulnerabilities, and immune microenvironmental remodeling in NF1-associated peripheral nerve sheath tumors, …

Ọmọtẹ-Ohwo-Re, Gloria Udhedhe-Oze
Wagadu: A Journal of Transnational Women's & Gender Studies
This eponymous narrative Ọmọtẹ Ohwo Re, loosely transliterated “female is human” in Isoko, is set in Emede, Isoko kingdom, Niger Delta, Nigeria during the late 1960s to early 1970s. It explores the lived experiences of the eponymous character who is denied the opportunity to obtain Western education by Chief Ebọ, her influential father, the sitting traditional ruler. Born into a polygamous home, she is the fourth and last child of her mother; but the seventh among eleven females. None is deemed worthy of an education because of their sex. In a twist of events, she defies this institutionalized marginalization and …
