Experimental Assessment of the Influence of Zooplankton Size and Density on Gizzard Shad Recruitment
Bremigan, Mary T.; Stein, Roy A. ( 1997 )Available prey influence fish recruitment, especially when size-dependent processes, such as starvation or predation, dictate larval survival. Yet, for zooplanktivorous larval fishes, quantitative assessments of how ... -
Exploring Spatial and Temporal Variation Within Reservoir Food Webs: Predictions for Fish Assemblages
Garvey, James E.; Dingledine, Natalie A.; Donovan, Nicholas S.; Stein, Roy A. ( 1998 )In the limnetic zones of small, highly productive reservoirs, young-of-year (YOY) gizzard shad (Dorosoma cepedianum) or threadfin shad (D. petenense) (henceforth, shad) often attain high densities during spring. Environmental ... -
Factors Affecting Survival of Age-0 Saugeye Stizostedion vitreum X S. canadense Stocked in Ohio Reservoirs
Stahl, Thomas P.; Thiede, Gary P.; Stein, Roy A.; Lewis, Edward M.; Austin, Milton R.; Culver, David A. ( 1996 )To explain variable stocking success of juvenile saugeye Stizostedion vitreum females x S. canadense males, we quantified survival of saugeyes in response to transport conditions, predation mortality, and prey resources ... -
Feeding Preferences of Omnivorous Gizzard Shad as Influenced by Fish Size and Zooplankton Density
Yako, Lisa A.; Dettmers, John M.; Stein, Roy A. ( 1996 )In Ohio reservoirs, larval gizzard shad Dorosoma cepedianum less than 30 mm total length consume only zooplankton but frequently switch to detritus as they grow longer than 30 mm. However, in laboratory studies without ... -
First-Summer Survival of Largemouth Bass Cohorts: Is Early Spawning Really Best?
Pine, William E. III; Ludsin, Stuart A.; DeVries, Dennis R. ( 2000 )Previous work has demonstrated that survival of largemouth bass Micropterus salmoides through the first year of life can be size dependent, favoring larger individuals. Because size, diet biomass, lipid accumulation, and ... -
First-Year Recruitment of Largemouth Bass: The Interdependency of Early Life Stages
Ludsin, Stuart A.; DeVries, Dennis R. ( 1997 )Four early life events (i.e., hatching, the ontogenetic diet shift to piscivory, fall lipid accumulation, and the first winter) are conceptualized as being critical to 1st-yr recruitment success of largemouth bass ... -
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 ...
