Overlap of North Pacific albatrosses with the U.S. west coastgroundfish and shrimp fisheries

Creator:: Guy, T. J., Jennings, S. L., Suryan, R. M., Melvin, E. F., Bellman, M. A., Ballance, L. T., Blackie, B. A., Croll, D. A., Deguchi, T., Geernaert, T. O., Henry, R. W., Hester, M., Hyrenbach, K. D., Jahncke, J., Kappes, M. A., Ozaki, K., Roletto, J., Sato, F., Sydeman, W. J., and Zamon, J. E.
Abstract:: We used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the...

Translocation and hand-rearing of the short-tailed albatross Phoebastria albatrus: early indicators of success for species conservation and island restoration

Creator:: Deguchi, Tomohiro, Suryan, Robert M., Ozaki, Kiyoaki, Jacobs, Judy F., Sato, Fumio, Nakamura, Noboru, and Balogh, Gregory R.
Abstract:: Many endemic species, particularly those on remote islands, have been driven to extinction or near extinction by anthropogenic influences. The short-tailed albatross Phoebastria albatrus once numbered in the millions but was thought to be extinct by the mid 20th century. Albatrosses, of the family Diomedeidae, are among the most threatened...

New approach for using remotely sensed chlorophyll a to identify seabird hotspots

Creator:: Suryan, Robert M., Santora, Jarrod A., and Sydeman, William J.
Abstract:: Satellite imagery of chlorophyll a concentration (chl a) provides the only holistic perspective of productivity in marine ecosystems worldwide, yet its utility for understanding and predicting the distribution of upper trophic-level predators remains equivocal. We tested the hypothesis that remotely sensed chl a measurements spanning a decade can predict marine...

Constancy and change in marine predator diets across a shift in oceanographic conditions in the Northern California Current

Creator:: Gladics, Amanda J., Suryan, Robert M., Brodeur, Richard D., Segui, Leah M., and Filliger, Laura Z.
Abstract:: Variable ocean conditions can greatly impact prey assemblages and predator foraging in marine ecosystems. Our goal was to better understand how a change in ocean conditions influenced dietary niche overlap among a suite of midtrophic-level predators. We examined the diets of three fishes and one seabird off central Oregon during...

Winter dispersal and activity patterns of post-breeding black-legged kittiwakes Rissa tridactyla from Prince William Sound, Alaska

Creator:: McKnight, Aly, Irons, David B., Allyn, Andrew J., Sullivan, Kelsey M., and Suryan, Robert M.
Abstract:: As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes...

Summer-time use of west coast US National Marine Sanctuaries by migrating sooty shearwaters (Puffinus griseus)

Creator:: Adams, Josh, MacLeod, Catriona, Suryan, Robert M., Hyrenbach, K. David, and Harvey, James T.
Abstract:: Non-breeding sooty shearwaters are the most abundant seabird in the California Current Large Marine Ecosystem (CCLME) during boreal spring and summer months. This, combined with relatively great energy demands, reliance on patchy, shoaling prey (krill, squid, and forage fishes), and unconstrained mobility free from central-place-foraging demands-make shearwaters useful indicators of...

Marine bird colony and at-sea distributions along the Oregon coast: Implications for marine spatial planning and information gap analysis

Creator:: Suryan, Robert M., Phillips, Elizabeth M., So, Khemarith, Zamon, Jeannette E., Lowe, Roy W., and Stephensen, Shawn W.
Abstract:: Increasingly diverse interests in commercial and recreational use of marine resources are creating new challenges for coastal ocean management. One concern of increased offshore use and development off the Oregon coast is the potential impact on marine bird populations. We summarized the primary surveys of seabird breeding colonies and at-sea...

State of the California Current 2014-15: Impacts of the Warm-Water "Blob"

Abstract:: In 2014, the California Current (~28˚–48˚N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38˚–43˚N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39˚N. Catches of juvenile rockfish (an...

Fishery-specific solutions to seabird bycatch in the U.S. West Coast sablefish fishery

Creator:: Good, Thomas P., Jannot, Jason E., Melvin, Edward F., Gladics, Amanda J., Suryan, Robert M., and Guy, Troy J.
Abstract:: Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...

Environmental drivers and reproductive consequences of variation in the diet of a marine predator

Creator:: Gladics, Amanda J., Suryan, Robert M., Parrish, Julia K., Horton, Cheryl A., Daly, Elizabeth A., and Peterson, William T.
Abstract:: Ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects of ocean state propagating to higher trophic levels. In many regions throughout their range, common murre (Uria aalge) exhibit narrow dietary breadth in feeding chicks and therefore are vulnerable to recruitment failures of dominant prey...
