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 ... -
Largemouth Bass Predation on Stocked Tiger Muskellunge
Stein, Roy A.; Carline, Robert F.; Hayward, Robert S. ( 1981 )To better understand why stocked esocids survive poorly, we estimated mortality rates of tiger muskellunge(F1 hybrid of female muskellunge Esox masquinongy * male northern pike E. lucius) that were placed into two Ohio ... -
Larval Gizzard Shad Success, Juvenile Effects, and Reservoir Productivity: Toward a Framework for Multi-System Management
Bremigan, Mary T.; Stein, Roy A. ( 1999 )Recruitment success of larval fishes can determine subsequent effects of older life stages on ecosystem structure and function. Because size and abundance of juvenile gizzard shad Dorosoma cepedianum determines, in large ... -
Larval Size and Recruitment Mechanisms in Fishes: Toward a Conceptual Framework
Miller, Thomas J.; Crowder, Larry B.; Rice, James A.; Marschall, Elizabeth A. ( 1988 )Understanding the mechanisms controlling recruitment in fishes is a major problem in fisheries science. Although the literature on recruitment mechanisms is large and growing rapidly, it is primarily species specific. ... -
Life After Death in Lake Erie: Nutrient Controls Drive Fish Species Richness, Rehabilitation
Ludsin, Stuart A.; Kershner, Mark W.; Blocksom, Karen A.; Knight, Roger L.; Stein, Roy A. ( 2001 )We explored the recent (1969–1996) dynamics of fish communities within Lake Erie, a system formerly degraded by eutrophication and now undergoing oligotrophication owing to phosphorus abatement programs. By merging bottom ... -
Linking Bluegill and Gizzard Shad Prey Assemblages to Growth of Age-0 Largemouth Bass in Reservoirs
Garvey, James E.; Stein, Roy A. ( 1998 )Either gizzard shad Dorosoma cepedianum or bluegills Lepomis macrochirus dominate prey assemblages in many small (<100 ha) Ohio reservoirs. Because gizzard shad spawn early in the spring and their offspring grow rapidly, ... -
Linking Landscapes and Food Webs: Effects of Omnivorous Fish and Watersheds on Reservoir Ecosystems
Vanni, Michael J.; Arend, Kristin K.; Bremigan, Mary T.; Bunnell, David B.; Garvey, James E.; Gonzalez, Maria J.; Renwick, William H.; Soranno, Patricia A.; Stein, Roy A. ( 2005 )Ecologists increasingly recognize the need to understand how landscapes and food webs interact.

Management Issues and Their Relative Priority within State Fisheries Agencies
Mather, Martha E.; Parrish, Donna L.; Stein, Roy A.; Muth, Robert M. ( 1995 )For researchers and managers to work together for greatest mutual benefit, researchers must understand what issues fisheries managers consider most important. To assess management priorities, we conducted a mail survey ... -
Manipulating Shad to Enhance Sport Fisheries in North America: An Assessment
DeVries, Dennis R.; Stein, Roy A. ( 1990-05 )Manipulating forage fish populations to enhance sport fisheries is a common management practice. Here we review the literature dealing with manipulations of gizzard shad Dorosoma cepedianum and threadfin shad D. petenense ... -

Kershner, Mark W.; Schael, Denise M.; Knight, Roger L.; Stein, Roy A.; Marschall, Elizabeth A. ( 1999 )Given the variable nature of the Lake Erie ecosystem, we investigated biotic and abiotic sources of variation for walleye (Stizostedion vitreum) growth, consumption, and population-wide predatory demand. We determined how ...
