The dynamics of a recovering fish stock: Georges Bank herring

Nonlinear dynamic features and co-predictability of the Georges Bank fish community

We examined evidence for nonlinear dynamics in fishery-independent survey data for an assemblage of 26 fish species on Georges Bank spanning the period 1963 to 2008. We used nonlinear time series analysis to determine (1) the presence of nonlinear dynamics in fish populations on Georges Bank, (2) the minimum number of dimensions required to effectively describe system dynamics, (3) the strength...

Surplus production dynamics in declining and recovering fish populations

Surplus production rates predicted by simple biomass dynamics models are generally expected to follow a simple dome-shaped pattern as population size changes and to show similar trajectories during population decline and recovery. Age-structured models, however, predict substantially lower surplus production rates during population recovery than during decline because of reduced mean fecundity,...

The impact of Central bank independence on stock market volatility

The new paradigm in monetary policymaking gives accent to central banks‘ Independence. It is widely accepted that in modern monetary policymaking, central banks have three key goals: price stability, output stability and financial stability. Recent studies on central bank independence mainly investigate the effects of central bank independence on economic stability. But the effectiveness of cen...

Genetic differentiation among Atlantic cod (Gadus morhua) from Browns Bank, Georges Bank, and Nantucket Shoals

The Atlantic cod (Gadus morhua) is a migratory gadid found on both sides of the North Atlantic. In the Northwest Atlantic, cod are distributed nearly continuously along the continental shelf from Greenland to North Carolina, spawning in relatively discrete, temporally stable areas, and different regions are regarded as different management units defined primarily by latitude and bathymetry (Ruz...
