phylogenetic relationships of the extinct st helena petrel pterodroma rupinarum olson 1975 procellariiformes Procellariidae based on ancient dna
Zoological Journal of the Linnean Society, 2014Co-Authors: Andreanna J Welch, Storrs L Olson, Robert C FleischerAbstract:Palaeontological studies show that three endemic procellariid seabird species became extinct on the remote island of St Helena in the South Atlantic Ocean. At least one of these, Pterodroma rupinarum Olson, 1975, is likely to have survived until human colonization of the island, although it is known only from subfossil bones. Several species of Pterodroma are distributed across the Atlantic, but the skull and bill of Pt. rupinarum were judged to be more similar to the Indo-Pacific Pterodroma rostrata group, which was recently split into the separate genus Pseudobulweria. We used ancient DNA techniques to sequence the mitochondrial cytochrome b gene of the extinct Pt. rupinarum, and conducted phylogenetic analyses to investigate the placement of this enigmatic taxon. In trees constructed using maximum likelihood and Bayesian inference, Pt. rupinarum did not group with Pseudobulweria, but instead fell within a strongly supported clade of Atlantic Pterodroma, including the endangered Black-capped [Pterodroma hasitata (Kuhl, 1820)] and Bermuda [Pterodroma cahow (Nichols & Mowbray, 1916)] petrels, as well as the Macaronesian petrels [Pterodroma madeira Mathews, 1934, Pterodroma feae (Salvadori, 1899) and Pterodroma deserta Mathews, 1934]. Pterodroma rupinarum shared a particularly close relationship with Pt. feae of the Cape Verde Islands, which is also the geographically closest species within the clade. Considering the osteological distinctiveness of Pt. rupinarum it was probably a separate species, or at least a highly diverged population that was isolated for a substantial period of time prior to its extinction. © 2013 The Linnean Society of London

A nomenclatural history of Audubon's Shearwater with designation of a neotype for Puffinus lherminieri Lesson, 1839 (Aves: Procellariidae)
Proceedings of the Biological Society of Washington, 2013Co-Authors: Storrs L OlsonAbstract:Abstract The nomenclatural history of the small Antillean species that now goes by the name Audubon's Shearwater Puffinus lherminieri is briefly summarized. The type material of Puffinus lherminieri Lesson, 1839, supposed to be in a museum in Rochefort, France, could not be located and is presumed lost. The stated type locality “ad ripas Antillarum” is so general as to encompass almost the entire breeding range of the species, which is widely distributed in the Antillean region and has been regarded as showing variation meriting subspecific designation. Although the type locality was apparently legitimately restricted to Guadeloupe in 1948 or earlier, it was elsewhere erroneously restricted to “Straits of Florida” from 1931 to 1998 and up to the present. To resolve these numerous conflicts and uncertainties, a neotype collected in Saint Barthelemy, once administratively part of Guadeloupe, is here designated.

Stasis and turnover in small shearwaters on Bermuda over the last 400 000 years (Aves: Procellariidae: Puffinus lherminieri group)
Biological Journal of the Linnean Society, 2010Co-Authors: Storrs L OlsonAbstract:The extinct species Puffinus parvus Shufeldt of Bermuda is shown to be synonymous with the living taxon Puffinus boydi of the Cape Verde islands. This species occurred on Bermuda throughout the last 400 000 years, during both glacial and interglacial intervals, and into the Holocene up until the arrival of humans when introduced predators evidently caused its extirpation. Subsequently, the island was colonized briefly by the Caribbean species Puffinus lherminieri, which in turn was extirpated from the island in the 20th Century. The indications are that P. boydi successfully outcompeted P. lherminieri on Bermuda until it was removed through human agency, thus closely paralleling the situation documented for two species of Megadyptes penguins in New Zealand. Thus P. lherminieri and P. boydi have long functioned as biological species and should be considered as full species along with the cold-water species Puffinus baroli of the North Atlantic. Restoration efforts for small shearwaters on Bermuda should now focus on P. boydi rather than P. lherminieri. © 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 99, 699–707.

a new species of shearwater of the genus calonectris aves Procellariidae from a middle pleistocene deposit on bermuda
Proceedings of the Biological Society of Washington, 2008Co-Authors: Storrs L OlsonAbstract:ABSTRACT Remains of at least 26 individuals of a Calonectris shearwater were recovered from a Pleistocene beach deposit on Bermuda that formed when sea-level was more than 21 m above present level during an interglacial (Marine Isotope Stage 11) 400,000 yr ago. Two prefledging juveniles in the sample indicate breeding on the island. This shearwater was the general size of C. d. diomedea of the Mediterranean but differs in proportions and in qualitative characters and is described as Calonectris wingatei, new species. The species appears to have become extinct shortly after the time of deposition, when rising sea-level is also thought to have caused the extinction of the Short-tailed Albatross Phoebastria albatrus on Bermuda. The Neogene history of the taxa of Calonectris in the Atlantic basin is examined in the context of major geological and oceanographic events.

Neotropical helminthology, 2021Co-Authors: Martha Brandao, Salvatore Siciliano, Marcia Chame, Rodrigo Machado, Jose L LuqueAbstract:During the winter of 2003 the seabird (Macronectes giganteus) was found scrawny at Atlântida Sul beach, north coast of State of Rio Grande do Sul – Brazil. Fresh fecal sample were collected at CECLIMAR (Centro de Estudos Costeiros, Limnologicos e Marinhos da Universidade Federal do Rio Grande do Sul) rehabilitation center and fixed in Railliet & Henry solution. Using spontaneous sedimentation technical to helminth eggs, 10 slides were obtained. All eggs found were of one species of Trichinelloidea superfamily (n=82). The eggs found here, are a new record of helminth parasite of Petrel.
