The broad distribution of Pacific sardine (Sardinops sagax) along the Pacif ic coast of North America makes it difficult for fisheries managers to identify regional stocks of this dominant small pelagic species. An investigation of morphometric characteristics of otoliths of Pacific sardine across most of their range revealed regional differences in populations. In a survey of over 2000 otoliths, all ages (with an emphasis on age-1 recruits) were compared. Principal components analysis, multivariate analysis of variance, and a novel method derived from regression and residuals calculations, termed perimeter-weight profiles (PWPs), revealed otolith similarities and differences. The results of the different approaches to statistical comparisons did not always agree. Sardine otoliths from Mexican waters were generally lighter and more lobate than those from U.S. and Canadian populations. Age-1 otoliths from northern California in 2006–07 tended to be heavier and smoother than those from other areas, including year-class cohorts from southern California. Comparisons of age-groups and year-classes of northern California otoliths with the use of the PWP models indicated signif icant trends in year-to-year patterns. In conjunction with other established indices of population structure, otolith PWPs are a useful tool for identifying local and regional stocks of Pacific sardine and may help distinguish populations of other fish species as well.

We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest frequency of occurrences were found north of central Oregon, along the coasts of Washington and Vancouver Island, and in California around San Francisco Bay. Migrations to the north off Washington and Vancouver were seen during spring to fall, but we found no evidence for large-scale seasonal migrations to the south during the fall or winter. The average weight of shad increased in deeper water. Sizes were also larger in early years of the study. Most were caught over a wide range of sea surface temperatures (11–17°C) and bottom temperatures (6.4–8.0°C). Abundance of shad on the continental shelf north of 44°N was highly correlated with counts of shad at Bonneville Dam on the Columbia River in the same year. Counts were negatively related to average weights and also negatively correlated with the survival of hatchery coho salmon (Oncorhynchus kisutch), indicating that survival of shad is favored by warm ocean conditions. Examining the catch during research cruises and commercial and recreational landings, we concluded that American shad along the Pacific coast have adapted to the prevailing environmental conditions and undertake only moderate seasonal migrations compared with the long seasonal migrations of shad along the Atlantic coast of North America. We suggest that the large spawning populations in the Columbia River and San Francisco Bay areas explain most of the distributional features along the Pacific coast.

A review of the relative productivity and value of the shad fisheries of North America as reflected in recorded commercial catches. A review of reasons for the decline that are biological and socioeconomic. Factors that have been held responsible are: pollution; destruction or impairment of spawning and nursery areas; overfishing; hydroelectric and canal dams; natural fluctuations in abundance. Natural catastrophes, parasites, and predators are not considered important in causing the decrease in commercial production. Attempts to rehabilitate the fisheries by various means of stocking artificially-reared fry and pond-reared fingerling shad, appear to have failed in every instance. Introduction of shad fry on the Pacific Coast has resulted in a major fishery. The most significant program is a controlled catch management plan, operating at this time [1953] only in Maryland.

EXTRACT (SEE PDF FOR FULL ABSTRACT): The seasonal cycles of coastal wind stress, adjusted sea level height (ASL), shelf currents and water temperatures off the west coast of North America (35°N to 48°N) were estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records of monthly ASL indicate that these two harmonics adequately represent the long-term monthly average seasonal cycle, and that the current measurement period is long enough to define the seasonal cycles, with relatively small errors in magnitude and phase.

EXTRACT (SEE PDF FOR FULL ABSTRACT): Data were extracted from the U.S. Navy Fleet Numerical Oceanographic Center Master Oceanographic Observation Data Set for a 200 km to 300 km wide coastal strip on the west coast of the United States. These data were averaged for the September through February (winter) and March through August (summer) intervals. The resulting winter temperature anomaly values show the El Nino signal in the CCC [Coastal California Current] as positive temperature anomalies from the surface to at least 300 m.

Although the prognosis of ambulatory heart failure (HF) has improved dramatically there have been few advances in the management of acute HF (AHF). Despite regional differences in patient characteristics, background therapy, and event rates, AHF clinical trial enrollment has transitioned from North America and Western Europe to Eastern Europe, South America, and Asia-Pacific where regulatory burden and cost of conducting research may be less prohibitive. It is unclear if the results of clinical trials conducted outside of North America are generalizable to US patient populations. This article uses AHF as a paradigm and identifies barriers and practical solutions to successfully conducting site-based research in North America.

Previous phylogeographical and palaeontological studies on the biota of northern North America have revealed a complex scenario of glacial survival in multiple refugia and differing patterns of postglacial recolonization. Many putative refugial regions have been proposed both north and south of the ice sheets for species during the Last Glacial Maximum, but the locations of many of these refugia remain a topic of great debate. In this study, we used a phylogeographical approach to elucidate the refugial and recolonization history of the herbaceous plant species Orthilia secunda in North America, which is found in disjunct areas in the west and east of the continent, most of which were either glaciated or lay close to the limits of the ice sheets. Analysis of 596-bp of the chloroplast trnS-trnG intergenic spacer and five microsatellite loci in 84 populations spanning the species' range in North America suggests that O.secunda persisted through the Last Glacial Maximum (LGM) in western refugia, even though palaeodistribution modelling indicated a suitable climate envelope across the entire south of the continent. The present distribution of the species has resulted from recolonization from refugia north and south of the ice sheets, most likely in Beringia or coastal regions of Alaska and British Columbia, the Washington/Oregon region in the northwest USA, and possibly from the region associated with the putative 'ice-free corridor' between the Laurentide and Cordilleran ice sheets. Our findings also highlight the importance of the Pacific Northwest as an important centre of intraspecific genetic diversity, owing to a combination of refugial persistence in the area and recolonization from other refugia.

North Amerlc8 W8S inundated by fJ major eplcontlnental sea during ihe C:retaceo.us Period. The sOljihw6rd transgression of th.e northern Boreal See along the ~\festern Interior Seaway resulted in a meetlng with the northward edv6nclng waters from the GUlf of Mexico (Obradovich and Cobban, 1975). Th1s link was 1n eXlstence by late Albien time and 6llowed for the comm1ngl1ng of the prol1ferous Arctic and Gulf rnar1ne faunas (F1g. 1). By early Campanlan time, there was a widening of B6ffln Bay wlth a slrnult8neous subsidence 1n the Arct1c Archlpelago and Sverdrup 6as1n (W11liam and Stelck, 1975). Williams and Burk (1964) found 6 break 1n the marines sedlmentatlon in the f1anltoba area, suggesting Bland corlnectlon from the Dlstrlct of Keewatln through eastern M6fl1toba to the lake Sl~perlor reglon, lmplying that the only dlrect connection between the Interlor Sea with Baffln Bay, was yia the Arct1c. This hiatus was also documented by Meek and Hayden (1861) ln the United states between the Niobrara and Pierre Format1ons. Jeletzky (1971) suggested that the retreat of the sea towards the east was by a serles of strong pulses resultlng in the regression of the Campanlan and M66str1chtlan seas. During ttle Cretaceous1 the r1s1ng Corl1111era caused the western shoreline of the Interlor Sea to migrate eastwards and the Cordillera'l detritus produced deltaic cornplexes from the Mackenzie Valley to Ne\N Mexlcoo The foreland basin was continually subslding and thls down\",arplng aided in the eastward m1gration of the western shorel1ne.

The following thesis presents an analysis of business-government relations within a neo-Marxist framework. Specifically, the discussion encompasses how the business interest group. the Business Council on National Issues, maintains consensus and unity amongst its monopoly capital members. Furthermore. the study elaborates on the process through which the group's interests are acknowledged and legitimized by the state under the "public interest" f8fue. Most of the literature pertaining to business-government relations within the context of interactions between business interest groups and the state, and such specific branches of the state as the government and/or the civil service. emphasize a liberal-pluralist perspective. Essentially, these writings serve to reflect and legitimate the current slatus quo. Marxist discourses on the subject, while attempting to transcend the liberal-pluralist framework. nevertheless suffer from either economic determinism .. ie., stressing the state's accumulation function but not its legitimation function or historical specificity. A cogent and comprehensive neo-Marxist analysis of business-government relations must discuss both the accumulation and legitimation functions of the state. The process by which the concerns of a particular business interest group become part of the state's policy agenda and subsequently are formulated and implemented into policies which legitimate its dominance is also studied. This inquiry is significant given the liberal-pluralist assumptions of a neutral state and that all interest groups compete "on a level playing field". The author's neo-Marxist paradigm rejects both of these assumptions. Building on concepts from nea-Marxist instrumentalism. structuralism. state monopoly capitalism, and forms and functions of the state perspectives. the author proposes that policies which legitimize the interests of the monopoly capital fraction cannot. be discerned only from the state's activities. per StJ. Clearly, if the liberal-pluralist 3 contention of multiple and conflicting interest groups, including those within the capitalist class, is taken at face value, M interest group such as the Business Council on National Issues (BCND, must somehow maintain. internal consensus Md unity amongst its members. Internal consensus amongst its members ensures that the state can better acknowledge and articulate its concerns into policies that maintain hegemonic dominance of the monopoly capital fraction under the "public interest" fllf.JJdq. The author contends that the BCNI focuses most of its interactions on the upper echelons of the civil service since it is this branch of the state which is most responsible for policy formulation and implementation. The author's paradigm is applied within the context of extensively analyzing newspaper coverage. BCN! publications, and other published sources, as well as a personal interview with an executive administrative member of the BeNI. The discussion focuses on how agreement and unity amongst the various interests of the monopoly capital fraction are maintained through the business organization, its policy scope, and finally its interactions with the state. The analysis suggests that while the civil service is an important player in expressing the interests of the BCNI's membership through policies which ostensibly also reflect the "public interest", it is not the only strategic target for the BCNI's interactions with the state. The author's research also highlights the importance of government officials at the Cabinet level and Cabinet Committees. Senior elected officials from the Federal government are also significant in avoiding intergovernmental or interprovincial conflict in implementing policies that legitimize hegemonic dominance of the monopoly capital fraction over other fractions and classes.

A hardcover Dictionary of the Zeta Psi Fraternity, edited by Arthur H. Motley and Harry B. Carpenter. An excerpt from the forward reads: "Having the sincere purpose of placing in the hands of all Brothers of the Fraternity a Directory of the full membership of our order, with addresses as perfectly correct as time and equipment would permit, supplemented with such alphabetical and geographical indices as will make the volume a handy and accurate cross-reference to our membership...". Included with this book is a typewritten letter from Gordon Waldie, treasurer of the Toronto Chapter of the Zeta Psi Fraternity thanking Mrs. Percy Band for the gift of the original initiation certificate of the late Hamilton K. Woodruff. Mr. Woodruff was one of the Charter members of the Fraternity and he was the 7th man initiated into this, the first Canadian chapter of any fraternity. The letter is dated Nov. 21, 1949. The full text is available in the Brock University Special Collections and Archives.
