Condition-dependent nesting in bluegill sunfish Lepomis macrochirus.
1. There are two prominent, nonmutually exclusive hypotheses to explain the timing of reproduction in animals: energetic constraint and adaptive behaviour. 2. We tested these hypotheses by quantifying the costs and benefits of nesting at different times in the season for male bluegill sunfish Lepomis macrochirus, a species with paternal care, in Lake Opinicon (Ontario, Canada). 3. The value of ...
متن کاملStreamwise vortices destabilize swimming bluegill sunfish (Lepomis macrochirus).
In their natural environment, fish must swim stably through unsteady flows and vortices, including vertical vortices, typically shed by posts in a flow, horizontal cross-flow vortices, often produced by a step or a waterfall in a stream, and streamwise vortices, where the axis of rotation is aligned with the direction of the flow. Streamwise vortices are commonly shed by bluff bodies in streams...
متن کاملHydrodynamics of the escape response in bluegill sunfish, Lepomis macrochirus.
Escape responses of fishes are one of the best characterized vertebrate behaviors, with extensive previous research on both the neural control and biomechanics of startle response performance. However, very little is known about the hydrodynamics of escape responses, despite the fact that understanding fluid flow patterns during the escape is critical for evaluating how body movement transfers ...
متن کاملBoldness and behavioral syndromes in the bluegill sunfish, Lepomis macrochirus
In recent years, evidence for interindividual variation in ‘‘personality’’ within animal populations has been accumulating. Personality is defined as consistency in an individual’s behavioral responses over time and/or across situations. One personality trait that has potentially far-reaching implications for behavioral ecology, and may provide insight into the mechanisms by which consistent be...
متن کاملToxicity of 19 adjuvants to juvenile Lepomis macrochirus (bluegill sunfish).
Nineteen adjuvants, many used as surfactants for aquatic herbicide applications, were applied in static bioassay to bluegill sunfish (Lepomis macrochirus) for 96 h to determine median lethal concentrations (LC50). Surfactants are added to the tank mix as a percentage (v/v) of the total volume, in contrast to herbicide application rates, which are usually expressed in kilograms per hectare. Two ...
