Errors in juvenile copepod growth rate estimates are widespread: problems with the Moult Rate method

Creator:: Hirst, A. G., Peterson, William T., and Rothery, P.
Abstract:: The Moult Rate (MR) method has been used widely to derive stage-specific growth rates in juvenile copepods. It is the most common field-based method. Unfortunately, the equation underlying the method is wrong and, consequently, large errors in juvenile growth rate estimates are widespread. The equation derives growth from the mean...

Climate Change Impacts on Marine Ecosystems

Creator:: Doney, Scott C., Ruckelshaus, Mary, Duffy, J. Emmett, Barry, James P., Chan, Francis, English, Chad A., Galindo, Heather M., Grebmeier, Jacqueline M., Hollowed, Anne B., Knowlton, Nancy, Polovina, Jeffrey, Rabalais, Nancy N., Sydeman, William J., and Talley, Lynne D.
Abstract:: In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wideranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Assessing population-level variation in the mitochondrial genome of Euphausia superba using 454 next-generation sequencing

Creator:: Johansson, Mattias, Duda, Elizabeth, Sremba, Angela L., Banks, Michael, and Peterson, William
Abstract:: The Antarctic krill (Euphausia superba Dana 1852) is widely distributed throughout the southern ocean, where it provides a key link between primary producers and upper trophic levels and supports a major commercial fishery. Despite its ecological and commercial importance, genetic population structure of the Antarctic kill remains poorly described. In...

Linking multidimensional functional diversity to quantitative methods: a graphical hypothesis-evaluation framework

Creator:: Boersma, Kate S., Dee, Laura E., Miller, Steve J., Bogan, Michael T., Lytle, David A., and Gitelman, Alix I.
Abstract:: Functional trait analysis is an appealing approach to study differences among biological communities because traits determine species' responses to the environment and their impacts on ecosystem functioning. Despite a rapidly expanding quantitative literature, it remains challenging to conceptualize concurrent changes in multiple trait dimensions (“trait space”) and select quantitative functional...

Crustal fissuring on the crest of the southern East Pacific Rise at 17°15′–40′S

Creator:: Wright, Dawn J., Haymon, Rachel M., White, Scott M., and Macdonald, Ken C.
Abstract:: Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...

Climate shifts the interaction web of a marine plankton community

Creator:: Francis, Tessa B., Scheuerell, Mark D., Brodeur, Richard D., Levin, Phillip S., Ruzicka, James J., Tolimieri, Nick, and Peterson, William T.
Abstract:: Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive...

Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...

Lidar-derived canopy architecture predicts brown creeper occupancy of two western coniferous forests

Creator:: Vogeler, Jody C., Hudak, Andrew T., Vierling, Lee A., and Vierling, Kerri T.
Abstract:: In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health of old-growth systems because they are strongly associated with habitat characteristics associated with old growth and are especially sensitive to...

Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models

Creator:: Ruzicka, James J., Steele, John H., Gaichas, Sarah K., Ballerini, Tosca, Gifford, Dian J., Brodeur, Richard D., and Hofmann, Eileen E.
Abstract:: End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the Northern California Current, the Central Gulf of Alaska, Georges Bank, and the Southwestern Antarctic Peninsula. High-quality data collected on system components...
