Evaluating How Local- and Regional-Scale Processes Interact to Regulate Growth of Age-0 Largemouth Bass
Garvey, James E.; Wright, Russell A.; Stein, Roy A.; Ferry, Kristen H. (2000-07)
Regional- and local-scale processes may interact to influence early growth and survival, thereby governing cohort strength. During summer through fall 1994–1996, we assessed how precipitation (a regional-scale process) and ...
Cold, Northern Winters: The Importance of Temperature to Overwinter Mortality of Age-0 White Crappies
McCollum, Arthur B.; Bunnell, David B.; Stein, Roy A. (2003)
Survival during the first winter of life can influence the recruitment of many fishes. We used field sampling and laboratory experiments to explore the mechanisms underlying first winter growth and survival of white crappie ...
Juvenile growth and survival of heat-shocked triploid hybrid saugeyes, Stizostedion vitreum × S. canadense
Garcia-Abiado, Mary Ann; Lynch, W. E. Jr.; Dabrowski, Konrad; Czesny, Sergiusz; Rinchard, Jacques; Stafford, J. (2002)
Triploid hybrid saugeyes may be a desirable stocking alternative because diploid saugeyes are fertile and can compromise the genetic integrity of parental stocks. Four groups of saugeye eggs were heat-shocked 5 min after ...
Predicting Crappie Recruitment in Ohio Reservoirs with Spawning Stock Size, Larval Density, and Chlorophyll Concentrations
Bunnell, David B.; Hale, R. Scott; Vanni, Michael J.; Stein, Roy A. (2006)
Stock-recruit models typically use only spawning stock size as a predictor of recruitment to a fishery. In this paper, however, we used spawning stock size as well as larval density and key environmental variables to ...
Testing for Evidence of Maternal Effects among Individuals and Populations of White Crappie
Bunnell, David B.; Scantland, Matthew A.; Stein, Roy A. (2005)
For an increasing number of species, maternal characteristics have been correlated with the characteristics of their eggs or larvae at the individual level. Documenting these maternal effects at the population level, ...
The impact of introduced round gobies (Neogobius me/anostomus) on phosphorus cycling in central Lake Erie
Bunnell, David B.; Johnson, Timothy B.; Knight, Carey T. (2005)
We used an individual-based bioenergetic model to simulate the phosphorus flux of the round goby (Neogobius melanostomus) population in central Lake Erie during 1995-2002. Estimates of round goby diet composition, growth ...
Biological Invasion Theory: Darwin's Contributions from The Origin of Species
Ludsin, Stuart A.; Wolfe, Andrea D. (2001)
Scale-Dependent Associations Among Fish Predation, Littoral Habitat, and Distributions of Crayfish Species
Garvey, James E.; Rettig, Jessica E.; Stein, Roy A.; Lodge, David M.; Klosiewski, Steven P. (2003)
To predict how species establish and disperse within novel communities, the spatial scale at which competition, predation, and habitat interact must be understood. We explored how these factors affect the distribution and ...
Induction of Gynogenesis in Muskellunge With Irradiated Sperm of Yellow Perch Proves Diploid Muskellunge Male Homogamety
Dabrowski, Konrad; Rinchard, Jacques; Lin, Feng; Garcia-Abiado, Mary Ann; Schmidt, Dana (2000)
Diploid gynogenesis was induced in muskellunge Esox masquinongy using UV-irradiated muskellunge sperm as the first step in producing monosex females. In this approach, we have to rely on negative controls as an indirect ...
The Cost of Dispersal: Predation as a Function of Movement and Site Familiarity in Ruffed Grouse
Yoder, James M.; Marschall, Elizabeth A.; Swanson, David A. (2004)
Ecologists often assume that dispersing individuals experience increased predation risk owing to increased exposure to predators while moving. To test the hypothesis that predation risk is a function of movement distance ...
