Frequently-anticipated questions:

What does this data set describe?

Title: Retrospective data on Fish, Birds, Mammals (B68)
The productivity of upper trophic level species in the eastern Bering Sea varies in response to climate variability and human forcing, although the relative contribution of these drivers and the underlying mechanisms remain poorly understood. This retrospective analysis will (1) quantify past patterns of variability and covariation among time series of productivity of selected fish, seabird, and marine mammal species; (2) test whether historical patterns and trends in these series are consistent with existing hypotheses; (3) suggest new hypotheses based on relationships among the productivity of different ecosystem components and relationships between their productivity and observed climate variability; and (4) provide functional forms and parameter estimates (and their uncertainty) that link the productivity of different ecosystem components to climate variability. The analysis will utilize existing data on productivity, including measures of recruitment, survival, and growth or condition, of major upper trophic level species. Results will contribute to the overall research program in two important ways. First, results will directly support the proposed modeling projects by providing parameters linking the productivity of individual species to climate variability, which is essential for predicting the effects of future climate variability. Second, identified relationships between climate and productivity can be incorporated into existing stock assessment models.
