Documenting the short‐tailed albatross (Phoebastria albatrus) clades historically present in British Columbia, Canada, through ancient DNA analysis of archaeological specimens [PDF]
Ecology and Evolution, 2022 The short‐tailed albatross (Phoebastria albatrus) is a threatened seabird whose present‐day range encompasses much of the North Pacific. Within this species, there are two genetic clades (Clades 1 and 2) that have distinctive morphologies and foraging ...

The effects of spatially heterogeneous prey distributions on detection patterns in foraging seabirds. [PDF]
PLoS ONE, 2012 Many attempts to relate animal foraging patterns to landscape heterogeneity are focused on the analysis of foragers movements. Resource detection patterns in space and time are not commonly studied, yet they are tightly coupled to landscape properties ...

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

DP and the Art of Perfect Positioning [PDF]
Modeling, Identification and Control, 2022 How does a vessel keep its position at sea without mooring? The answer is through dynamic positioning, or DP. Advanced technology, combining position reference sensors, computers, propellers and thrusters, is used to counteract environmental forces such ...

Successful Long-Distance Breeding Range Expansion of a Top Marine Predator
Frontiers in Ecology and Evolution, 2021 Little is known about the effects of large-scale breeding range expansions on the ecology of top marine predators. We examined the effects of a recent range expansion on the breeding and foraging ecology of Laysan albatrosses (Phoebastria immutabilis ...

A computed tomography‐based survey of paramedullary diverticula in extant Aves
The Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023 Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.
