An integrated approach to historical population assessment of the great whales: case of the New Zealand southern right whale

Creator:: Jackson, Jennifer A., Carroll, Emma L., Smith, Tim D., Zerbini, Alexandre N., Patenaude, Nathalie J., and Baker, C. Scott
Abstract:: Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the...

A taxonomic and distributional study of the rhodolith-forming species Lithothamnion muelleri (Corallinales, Rhodophyta) in the Eastern Pacific Ocean

Creator:: Robinson, Nestor M., Hansen, G. I., Fernandez-Garcia, C., and Riosmena-Rodriguez, R.
Abstract:: Lithothamnion rnuelleri is reported for the first time as one of the main components of rhodolith beds along the Eastern Pacific Ocean based on samples from Washington State (USA), Pacific Baja California (Mexico), southern Nicaragua, and Costa Rica. Individual rhodoliths ranged from fruticose to lumpy in morphology, and bi-sporangial, tetrasporangial,...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:: Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.
Abstract:: Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

Hydrothermal activity in the Northwest Lau Backarc Basin: Evidence from water column measurements

Creator:: Lupton, J. E., Arculus, R. J., Resing, J., Massoth, G. J., Greene, R. R., Evans, L. J., and Buck, N.
Abstract:: The Northwest Lau Backarc Basin, consisting of the Northwest Lau Spreading Center (NWLSC) and the Rochambeau Rifts (RR), is unique in having elevated ³He/⁴He ratios (up to 28 R[subscript a]) in the erupted lavas, clearly indicating a hot spot or ocean island basalt (OIB)-type signature. This OIB-type helium signature does...

Marine, Estuarine, and Diadromous Fish Stocks at Risk of Extinction in North America (Exclusive of Pacific Salmonids)

Creator:: Musick, J. A., Harbin, M. M., Berkeley, S. A., Burgess, G. H., Eklund, A. M., Findley, L., Gilmore, R. G., Golden, J. T., Ha, D. S., Huntsman, G. R., McGovern, J. C., Sedberry, G. R., Parker, S. J., Poss, S. G., Sala, E., Schmidt, T. W., Weeks, H., and Wright, S. G.
Abstract:: The problem of extinction in the sea has been recognized only recently by the scientific community (Roberts and Hawkins 1999). For the last decade, the American Fisheries Society (AFS) has pursued an initiative to identify marine fish stocks that may be at risk of extinction in North America (Musick 1998;...

Visual discrimination and memory of Enteroctopus dofleini, the Giant Pacific Octopus

Creator:: Boyle, Virinda R.
Abstract:: This study evaluated the memory and visual discrimination capabilities of Enteroctopus dofleini, the Giant Pacific Octopus. Octopuses have been known to have advance sensory capabilities and through this study we challenged our specimen to remember and actively choose a specific patterned jar based on a visual pattern and positive reinforcement....

Diet manipulations and color changes in Pisaster ochraceus

Creator:: Taylor, Katlyn R.
Abstract:: It has been observed and documented that Pisaster ochraceus has very striking colors, but the reasons behind the coloration are still unknown. Three coloration categories were determined and used for a feeding trial study to investigate the effects of diet on coloration in Pisaster ochraceus. This study involved 30 hand...

Differential gene expression between fall- and spring-run Chinook salmon assessed by long serial analysis of gene expression

Creator:: Bernier, Jeremiah C., Birkeland, Shanda R., Cipriano, Michael J., McArthur, Andrew G., and Banks, Michael A.
Abstract:: Of all Pacific salmonids, Chinook salmon Oncorhynchus tshawytscha display the greatest variability in return times to freshwater. The molecular mechanisms of these differential return times have not been well described. Current methods, such as long serial analysis of gene expression (LongSAGE) and microarrays, allow gene expression to be analyzed for...
