Landscape dynamics and resulting species interactions: the cod-capelin system in the southeastern Bering Sea

Creator:: Ciannelli, Lorenzo and Bailey, Kevin Mclean
Abstract:: 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...

Do walleye pollock exhibit flexibility in where or when they spawn based on variability in water temperature?

Creator:: Bacheler, Nathan M., Ciannelli, Lorenzo, Bailey, Kevin Mclean, and Bartolino, Valerio
Abstract:: Environmental variability is increasingly recognized as a primary determinant of year-class strength of marine fishes by directly or indirectly influencing egg and larval development, growth, and survival. Here we examined the role of annual water temperature variability in determining when and where walleye pollock (Theragra chalcogramma) spawn in the eastern...

Consequence of a superabundance of larval walleye pollock Theragra chalcogramma in the Gulf of Alaska in 1981

Creator:: Duffy-Anderson, J. T., Bailey, Kevin Mclean, and Ciannelli, Lorenzo
Abstract:: Abundances of larval walleye pollock in Shelikof Strait, Gulf of Alaska, in 1981 were far greater than any recorded estimates before that time or since (some patch estimates exceeded 100000 larvae per 10 m²). In spite of this extraordinary input, the ensuing 1981 year class was relatively poor. An examination...

Climate and Demography Dictate the Strength of Predator-Prey Overlap in a Subarctic Marine Ecosystem

Creator:: Hunsicker, Mary E., Ciannelli, Lorenzo, Bailey, Kevin M., Zador, Stephani, and Stige, Leif Christian
Abstract:: There is growing evidence that climate and anthropogenic influences on marine ecosystems are largely manifested by changes in species spatial dynamics. However, less is known about how shifts in species distributions might alter predator-prey overlap and the dynamics of prey populations. We developed a general approach to quantify species spatial...

A probabilistic cellular automata approach for predator-prey interactions of arrowtooth flounder (Atheresthes stomias) and walleye pollock (Theragra chalcogramma) in the eastern Bering Sea

Creator:: Chen, Kun, Chan, Kung-Sik, Bailey, Kevin Mclean, Aydin, Kerim, and Ciannelli, Lorenzo
Abstract:: 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...

Environmental factors influencing larval walleye pollock Theragra chalcogramma feeding in Alaskan waters

Creator:: Porter, Steven M., Ciannelli, Lorenzo, Hillgruber, Nicola, Bailey, Kevin Mclean, Chan, Kung-Sik, Canino, Michael F., and Haldorson, Lew J.
Abstract:: This study examines potential interactions among the environmental variables likely to affect larval walleye pollock Theragra chalcogramma feeding in the sea. Walleye pollock larvae were sampled from Shelikof Strait, Gulf of Alaska, and from the eastern Bering Sea, with corresponding environmental data. Variables used in our study were time spent...

Theory, consequences and evidence of eroding population spatial structure in harvested marine fishes: a review

Creator:: Ciannelli, Lorenzo, Fisher, Jonathan A. D., Skern-Mauritzen, Mette, Hunsicker, Mary E., Hidalgo, Manuel, Frank, Kenneth T., and Bailey, Kevin M.
Abstract:: In marine populations, spatial structure arises over a wide range of scales and forms hierarchical aggregations. Changing spatial structure can alter the demographic and life history trait variation within populations and subject individuals to both novel environmental conditions and interspecific interactions. Thus, changes in the spatial structure of marine populations...

Transdisciplinary graduate education in marine resource science and management

Creator:: Ciannelli, Lorenzo, Hunsicker, Mary, Beaudreau, Anne, Finley, Carmel, Heppell, Selina, Conway, Flaxen, Bailey, Kevin, Crowder, Larry B., Webb, Colleen, Reynolds, John, Sagmiller, Kay, Anderies, John M., Hawthorne, David, Parrish, Julia, Conway, Flaxen D. L., and Chigbu, Paulinus
Abstract:: In this article we consider the current educational needs for science and policy in marine resource management, and we propose a way to address them. The existing literature on cross-disciplinary education in response to pressing environmental problems is vast, particularly in conservation biology. However, actual changes in doctoral-level marine science...

Functional responses and scaling in predator–prey interactions of marine fishes: contemporary issues and emerging concepts

Wilson, Link, Jason S., Essington, Timothy E., Gaichas, Sarah, Anderson, Todd W., Brodeur, Richard D., Chan, Kung-Sik, Chen, Kun, Englund, Goran, Frank, Kenneth T., Freitas, Vania, Hixon, Mark A., Hurst, Thomas, Johnson, Darren W., Kitchell, James F., Reese, Doug, Rose, George A., Sjodin, Henrik, Sydeman, William J., van der Veer, Henk W., Vollset, Knut, and Zador, Stephani
Abstract:: Predatorprey interactions are a primary structuring force vital to the resilience of marine communities and sustainability of the worlds oceans. Human influences on marine ecosystems mediate changes in species interactions. This generality is evinced by the cascading effects of overharvesting top predators on the structure and function of marine ecosystems....

Population growth across heterogeneous environments: effects of harvesting and age structure

Creator:: Durant, Joel M., Hidalgo, Manuel, Rouyer, Tristan, Hjermann, Dag O., Ciannelli, Lorenzo, Eikeset, Anne Maria, Yaragina, Natalia, and Stenseth, N. C.
Abstract:: Population growth is affected by several factors such as climate, species interaction and harvesting pressure. However, additional complexity can arise if fishing increases the sensitivity to environmental variability. To predict the effects of fisheries and climate on marine populations, there is a need for improved understanding of how they affect...
