Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia

open access: yesConservation Biology, EarlyView.
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Foraging Behavior and Energetics of Albatrosses in Contrasting Breeding Environments

open access: yesFrontiers in Marine Science, 2017
Animals can maximize fitness by optimizing energy acquisition through the selection of favorable foraging habitats, but trade-offs exist between time spent in preferred feeding habitats, energetic costs of travel, and reproductive constraints.

Distribution, relative abundance and developmental morphology of paralarval cephalopods in the Western North Atlantic Ocean [PDF]

open access: yes, 2001
Paralarval and juvenile cephalopods collected in plankton samples on 21 western North Atlantic cruises were identified and enumerated. The 3731 specimens were assigned to 44 generic and specific taxa.

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, EarlyView.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

‘Anthropomorphic drones’ and colonized bodies: William Gibson’s the peripheral [PDF]

open access: yes, 2016
William Gibson tends to write in trilogies, as his first nine novels show. These series – the Sprawl, the Bridge, and the Blue Ant trilogies – are set in three different time periods and are populated by characters who reappear from one book to the next.

The Acts of Eadburg: drypoint additions to Oxford, Bodleian Library, MS Selden Supra 30

open access: yesEarly Medieval Europe, EarlyView.
In 1913, two drypoint additions were identified in Oxford, Bodleian Library, MS Selden Supra 30 (SS30), an eighth‐century Southumbrian copy of the Acts of the Apostles. It was suggested that these additions, cut into the membrane of p. 47, were abbreviations of the Old English female name, Eadburg. Just over a century later, many more drypoint markings

Adjusting time-of-day and depth of fishing provides an economically viable solution to seabird bycatch in an albacore tuna longline fishery

open access: yesScientific Reports, 2023
Marine megafauna exposed to fisheries bycatch belong to some of the most threatened taxonomic groups and include apex and mesopredators that contribute to ecosystem regulation. Fisheries bycatch is a major threat to the conservation of albatrosses, large

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

open access: yesJournal of Anatomy, EarlyView.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

DNA Metabarcoding as a Marine Conservation and Management Tool: A Circumpolar Examination of Fishery Discards in the Diet of Threatened Albatrosses

open access: yesFrontiers in Marine Science, 2017
Almost all of the world's fisheries overlap spatially and temporally with foraging seabirds, with impacts that range from food supplementation (through scavenging behind vessels), to resource competition and incidental mortality. The nature and extent of
