Fish Cohort Dynamics: Application of Complementary Modeling Approaches
DeAngelis, Donald L.; Rose, Kenneth A.; Crowder, Larry B.; Marschall, Elizabeth A.; Lika, D. ( 1993 )The recruitment to the adult stock of a fish population is a function of both environmental conditions and the dynamics of juvenile fish cohorts. These dynamics can be quite complicated and involve the size structure of ... -
Food Consumption and Growth of Three Esocids: Field Tests of a Bioenergetic Model
Wahl, David H.; Stein, Roy A. ( 1991 )We quantified diet and compared field estimates of growth and daily ration with predictions from a bioenergetic model for young-of-year muskellunge Esox masquinongy, northern pike E. lucius. and tiger muskellunge E. ... -
Food Consumption by Larval Gizzard Shad: Zooplankton Effects and Implications for Reservoir Communities
Dettmers, John M.; Stein, Roy A. ( 1992 )Because peak abundance of larval gizzard shad Dorosoma cepedianum occurs simultaneously with the midsummer decline of macrozooplankton in Ohio reservoirs, we hypothesized that zooplanktivory by larval gizzard shad caused ... -
Food-web regulation by a planktivore: exploring the generality of the trophic cascade hypothesis
Stein, Roy A.; DeVries, Dennis R.; Dettmers, John M. ( 1995 )The trophic cascade hypothesis currently being tested in north temperate systems may not apply to open-water communities in lower latitude U.S. reservoirs. These reservoir communities differ dramatically from northern lakes ... -
Foraging in a patchy environment: prey-encounter rate and residence time distributions
Marschall, Elizabeth A.; Chesson, Peter L.; Stein, Roy A. ( 1989 )Small bluegill sunfish, Lepomis macrochirus, foraging among patches in the laboratory did not search systematically within a patch; their intercapture intervals did not differ from a model of random prey encounter within ... -
A Framework for Understanding Atlantic Salmon (Salmo salar) Life History
Marschall, Elizabeth A.; Quinn, Thomas P.; Roff, Derek A.; Hutchings, Jeffrey A.; Metcalfe, Neil B.; Bakke, Tor A.; Saunders, Richard L.; Poff, N. Leroy ( 1998 )We took a hierarchical approach to understanding Atlantic salmon (Salmo salar) life history patterns by first comparing salmonids to other teleosts, next comparing Atlantic salmon to other salmonids, and finally, ... -
From Star Charts to Stoneflies: Detecting Relationships in Continuous Bivariate Data
Garvey, James E.; Marschall, Elizabeth A.; Wright, Russell A. ( 1998 )Within many ecological systems, relationships between controlling factors and associated response variables are complex. In many cases, the response should vary little when the controlling factor exerts strong effects. ... -
Gape-dependent Larval Foraging and Zooplankton Size: Implications for Fish Recruitment across Systems
Bremigan, Mary T.; Stein, Roy A. ( 1994 )Small gape of zooplanktivorous larval fish limits their prey size; yet, within constraints set by gape, zooplankton size eaten influences larval growth and ultimately survival. To determine if optimal zooplankton size ... -
Growth Rate Variation and Larval Survival: Inferences from an Individual-Based Size-Dependent Predation Model
Rice, James A.; Miller, Thomas J.; Rose, Kenneth A.; Crowder, Larry B.; Marschall, Elizabeth A.; Trebitz, Anett S.; DeAngelis, Donald L. ( 1993 )We used an individual-based Monte Carlo simulation model to explore how changes in the mean and variance of growth rates of individuals in a larval fish cohort interact with size-dependent predation to affect the number and ... -
Habitat Selection by Smallmouth Bass in Response to Physical Characteristics of a Simulated Stream
Sechnick, Carolyn W.; Carline, Robert F.; Stein, Roy A.; Rankin, Edward T. ( 1986 )Juvenile (14-16 cm total length) and adult (24-26 cm) smallmouth bass Micropterus dolomieui were studied in a laboratory stream tank to determine the influence of light, current velocity, substrate, and cover on habitat ... -
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 ... -
In search of the optimal management strategy for Arabian oryx
Treydte, Anna C.; Williams, Joseph B.; Bedin, Eric; Ostrowski, Stephane; Seddon, Phillip J.; Marschall, Elizabeth A.; Waite, Thomas A.; Ismail, Khairy ( 2001 )Extirpated from the wild in 1972 by overhunting, Arabian oryx (Oryx leucoryx) were re-introduced in Saudi Arabia in March 1990; 17 oryx were released into Mahazat as-Sayd, a 2244 km2 fenced reserve in westcentral Arabia, ... -
Increased Coprophagic Activity of the Beetle, Tenebrio molitor, on Feces Containing Eggs of the Tapeworm, Hymenolepis diminuta
Pappas, Peter W.; Marschall, Elizabeth A.; Morrison, Sarah E.; Durka, Geraldine M.; Daniel, Cary S. ( 1995 )When provided with fecal pellets from uninfected (control) rats and rats infected with the tapeworm Hymenolepis diminuta, more fed and starved (72 h) female and starved male Tenebrio molitor fed on fecal pellets from ... -
Increased parental care cost for nest-guarding fish in a lake with hyperabundant nest predators
Steinhart, Geoffrey B.; Weaver, Stephanie; Stein, Roy A.; Marschall, Elizabeth A.; Sandrene, Melissa E. ( 2005 )Although parental care increases offspring survival, providing care is costly, reducing parental growth and survival and, thereby, compromising future reproductive success. To determine if an exotic benthic predator might ... -
Indirect Effects of Predation in a Freshwater, Benthic Food Chain
Bronmark, Christer; Klosiewski, Steven P.; Stein, Roy A. ( 1992 )Theories of cascading trophic interactions provide specific predictions regarding the forces that regulate populations across trophic levels. Reducing predators in a food chain with three trophic levels should permit ... -
Individual growth and foraging responses of age-0 largemouth bass to mixed prey assemblages during winter
Micucci, Stephanie M.; Garvey, James E.; Wright, Russell A.; Stein, Roy A. ( 2003 )We conducted an outdoor pool experiment at a mid-temperate latitude (Ohio, 40°N) to determine how commonly occurring prey assemblages affect individual foraging and growth of individually marked, age-0 largemouth bass ... -
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 ... -
Influence of Larval Gizzard Shad (Dorosoma cepedianum) Density on Piscivory and Growth of Young-of-Year Saugeye (Stizostedion vitreum x S. canadense)
Stahl, Thomas P.; Stein, Roy A. ( 1994 )Growth and survival of young-of-year saugeye (Stizostedion vitreum x S. canadense) (stocked into Ohio reservoirs to create sport fisheries) are probably influenced by prey availability, variations in which may account for ... -
Interactive Influence of Turbidity and Light on Larval Bluegill (Lepomis macrochirus) Foraging
Miner, Jeffrey G.; Stein, Roy A. ( 1993 )In a series of in situ enclosure experiments with larval bluegill (lepomis macrochirus), we demonstrate that turbidity from suspended sediments reduces bluegill consumption of crustacean zooplankton, primarily cyclopoid copepods ... -
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 ...
