Environmental conditions can have spatially complex effects on the dynamics of marine fish stocks that change across life-history stages. Yet the potential for non-stationary environmental effects across multiple dimensions, e.g. space and ontogeny, are rarely considered. In this study, we examined the evidence for spatial and ontogenetic non-stationary temperature effects on Pacific hake Merluccius productus biomass along the west coast of North America. Specifically, we used Bayesian additive models to estimate the effects of temperature on Pacific hake biomass distribution and whether the effects change across space or life-history stage. We found latitudinal differences in the effects of temperature on mature Pacific hake distribution (i.e. age 3 and older); warmer than average subsurface temperatures were associated with higher biomass north of Vancouver Island, but lower biomass offshore of Washington and southern Vancouver Island. In contrast, immature Pacific hake distribution (i.e. age 2) was better explained by a nonlinear temperature effect; cooler than average temperatures were associated with higher biomass coastwide. Together, our results suggest that Pacific hake distribution is driven by interactions between age composition and environmental conditions and highlight the importance of accounting for varying environmental effects across multiple dimensions.

This chapter evaluates multiple dimensions of the global power shift from the incumbent G5/G7 powers to the rising powers, especially the members of the BRICS (Brazil, Russia, India, China, and South Africa). Taking note of alternative conceptualizations of interstate “power,” the text maps the redistribution of economic capabilities from the G7 to the BRICS, most particularly the relative rise of China and decline of Japan, and especially Europe. Given these clear trends in measurable material capabilities, the BRICS have obtained considerable autonomy from outside pressures. Although the BRICS’ economic, financial, and monetary capabilities remain uneven, their relative positions have improved steadily. Via extensive data analysis, the chapter finds that whether one examines China alone or the BRICS as a group, BRICS members have achieved the necessary capabilities to challenge the global economic and financial leadership of the currently dominant powers, perhaps even the United States one day.
