Aging In The Shadows: Szekler Cemeteries And The Case For Recognizing Elderly Populations In Bioarchaeology, Katie M. Mcgrath Mar 2026

Aging In The Shadows: Szekler Cemeteries And The Case For Recognizing Elderly Populations In Bioarchaeology, Katie M. Mcgrath

USF Tampa Graduate Theses and Dissertations

The study of aging in past populations lies at the intersection of bioarchaeology and paleodemography, offering insight into both biological processes and lived social experience. Despite this potential, older adults are often rendered “invisible” in skeletal assemblages due to methodological and cultural biases. This thesis addresses this gap through a rare, community-based study of aging among the Székely population of Transylvania. By integrating osteological analysis of individuals (11th–19th centuries) from the archaeological Papdomb church cemetery with demographic data derived from the modern cemetery headstones (ca.1850–present), this research examines patterns of aging, longevity, and elder visibility across a culturally and spatially …


Population Survey Of Southern Buller’S Albatross Thalassarche Bulleri Bulleri On The Solander Islands / Hautere, March 2024, Peter G. H. Frost, Barry G. Baker, Johannes H. Fischer, Paul M. Sagar Nov 2025

Population Survey Of Southern Buller’S Albatross Thalassarche Bulleri Bulleri On The Solander Islands / Hautere, March 2024, Peter G. H. Frost, Barry G. Baker, Johannes H. Fischer, Paul M. Sagar

Marine Ornithology

An aerial photographic survey of the Southern Buller's Albatross Thalassarche bulleri bulleri population breeding on the Solander Islands / Hautere was undertaken on 09 March 2024, mid-way through the birds' incubation period. Overall, 6,761 individuals were counted: 6,215 (92%) on Great Solander and 546 (8%) on Little Solander. Of these, 4,213 were sitting on nests, 368 were partners to sitting birds, 573 were standing near empty nests, and 145 were apparently loafing. The status of the remaining 1,462 individuals (22% of the total) was uncertain. Assuming that their status was in the same proportions to those of the clearly observed …


Trends In Density, Abundance, And Response To Storm Damage For Westland Petrels Procellaria Westlandica, 2007-2019, Susan M. Waugh, Christophe Barbraud, Karine Delord, Kate L.J. Simister, G. Barry Baker, Georgie K. Hedley, Kerry-Jayne Wilson, Douglas R.D. Rands Jul 2025

Trends In Density, Abundance, And Response To Storm Damage For Westland Petrels Procellaria Westlandica, 2007-2019, Susan M. Waugh, Christophe Barbraud, Karine Delord, Kate L.J. Simister, G. Barry Baker, Georgie K. Hedley, Kerry-Jayne Wilson, Douglas R.D. Rands

Marine Ornithology

The density and distribution of Westland Petrel burrows was assessed over a 12-year period (2007–2019). During that time, burrow density increased while occupancy remained stable, commensurate with an annual population growth rate of 1.022 (95% confidence interval: 0.971–1.076), as estimated using mark recapture data. From our surveys, we estimated a 2019 baseline population of ~6200 breeding pairs and a world population of 13 800–17600 individuals, covering around 95% of the population. Transects were conducted to establish the location and density of 17 petrel sub-colonies in rugged, untracked terrain in Paparoa National Park, West Coast, New Zealand. Major storms in 2014–2018 …


Nightly Colony Attendance Patterns Of Provisioning Cassin's Auklet Ptychoramphus Aleuticus Are Consistent And Synchronous, Laura Mcfarlane Tranquilla, John L. Ryder, Louise K. Blight, Patrick D. O’Hara, Douglas F. Bertram Jul 2025

Nightly Colony Attendance Patterns Of Provisioning Cassin's Auklet Ptychoramphus Aleuticus Are Consistent And Synchronous, Laura Mcfarlane Tranquilla, John L. Ryder, Louise K. Blight, Patrick D. O’Hara, Douglas F. Bertram

Marine Ornithology

We conducted a multi-year (1999–2001) radio telemetry study to determine patterns of colony attendance among breeding Cassin’s Auklets Ptychoramphus aleuticus during the chick-rearing period on Triangle Island in British Columbia, Canada. A total of 1 625 detections were obtained for 80 individual birds (24–28 birds per year), each detected 20.3 times on average. We found that colony attendance (arrival times, departure times, in-burrow shift duration) and foraging trip duration (i.e., time away from the colony) were remarkably synchronous among individuals and years. On average, birds arrived in a pulse after darkness, with 67% of returns between 23h15 and 00h15 and …


Decrypting The Breeding Biology Of The Elusive And Declining Tahiti Petrel Pseudobulweria Rostrata, Angelique Pagenaud, Karen Bourgeois, Léna Payandi, Wilfried Weiss, Éric Vidal, Andreas Ravache Jul 2025

Decrypting The Breeding Biology Of The Elusive And Declining Tahiti Petrel Pseudobulweria Rostrata, Angelique Pagenaud, Karen Bourgeois, Léna Payandi, Wilfried Weiss, Éric Vidal, Andreas Ravache

Marine Ornithology

Among procellariids, the Tahiti Petrel Pseudobulweria rostrata is one of the most endangered and least known species. Its global populations are declining, yet demographic and ecological studies remain scarce. Understanding the breeding cycle and behavior of Tahiti Petrel adults and chicks is essential to develop effective protection measures. To address this knowledge gap, Tahiti Petrel colonies of various sizes were studied at three sites in New Caledonia, with extensive sampling at two main sites and limited sampling at a third. A total of 157 burrows were monitored for up to two years using endoscopic cameras and camera traps. This allowed …
