  Citation × Citation Citation Abstract Copy Title: A probabilistic cellular automata approach for predator-prey interactions of arrowtooth flounder (Atheresthes stomias) and walleye pollock (Theragra chalcogramma) in the eastern Bering Sea Author: Chen, Kun, Chan, Kung-Sik, Ciannelli, Lorenzo, Bailey, Kevin Mclean, Aydin, Kerim We developed a hybrid cellular automata (CA) modelling approach to explore the dynamics of a key predator–prey interaction in a marine system; our study is motivated by the quest for better understanding of the scale and heterogeneity-related effects on the arrowtooth flounder (Atheresthes stomias) and walleye pollock (Theragra chalcogramma) dynamics during the summer feeding season in the eastern Bering Sea (EBS), but can be readily extended to other systems. The spatially explicit and probabilistic CA model incorporates individual behaviours and strategies and local interactions among species, as well as spatial and temporal heterogeneity due to geographical and (or) environmental changes in the physical environment. The model is hybridized, with an individual-based model (IBM) approach for increasing its capacity and continuum and for balancing between computational efficiency and model validity, which makes it suitable for simulating predator–prey dynamics in a large, complex ecological environment. We focus on the functional and aggregative responses of predators to prey density at different spatial scales, the effects of individual behaviours, and the impacts of systematic heterogeneity. Simulations from the model with suitable parameter values share qualitatively similar features found in field observations, e.g., local aggregations around hydrographical features. Spatial heterogeneity is an important aspect of whether local-scale functional and aggregative responses reflect those operating over large, or global, scales.

  Citation × Citation Citation Abstract Copy Title: Landscape dynamics and resulting species interactions: the cod-capelin system in the southeastern Bering Sea Author: Ciannelli, Lorenzo, Bailey, Kevin Mclean Capelin are a major component of cod diet in many ecosystems of the North Atlantic. In the Bering Sea, however, the percentage of capelin found in Pacific cod stomachs is negligible. We hypothesize that the landscape (or ‘seascape’) features of hydrography and bathymetry of the Bering Sea impose a constraint on the distribution of cod and capelin that contributes to their spatial segregation and ultimately, to their uniquely weak trophic link. We analyzed a long-term data collection (1972 to 2001) on Pacific cod and capelin catches and feeding interactions, and developed a new metric to quantify the spatially explicit overlap between a predator and a prey. Our analysis indicates that cod and capelin distributions respond to the thermal conditions of the Bering Sea. Typically, a frigid water mass is present on the middle portion of the shelf, and cod distribution is confined to the southern side of the cold pool, while capelin is confined to the north. However, in warm years the middle shelf is penetrated by thermal gateways (between 1 and 6°C), allowing cod to invade the capelin habitat. In this situation, when cod and capelin overlap, cod feed heavily on capelin. The annual index of cod and capelin overlap is correlated with the Pacific Decadal Oscillation (PDO) index, a climate indicator of the North Pacific. The width of the thermal gateways in the middle shelf is also correlated with the PDO. These results point to a direct causal link, from climate and thermal conditions of the Bering Sea shelf, to cod and capelin distribution, and ultimately to their overlap and trophic interactions.
