Relationships Among Swimming Ability, Habitat use, and Morphology of Freshwater Fishes from Texas and Louisiana
Relationships between swimming ability and both habitat selection and morphology were assessed for freshwater fishes from Gulf slope, Rio Grande, Red River, and Canadian River drainages in Texas and Louisiana to better understand the influence that flow has on structuring fish assemblages. Swimming …

Spontaneous Alternating Behavior in <em>Paramecium caudatum</em> and <em>Paramecium multimicronucleatum</em>
… in nature; and 3) there were differences in swimming ability between <em>Paramecium caudatum</em> and <em>P. muItimicronucleatum</em>.</p> <p>SAB occurred in short mazes in both species of <em>Paramecium</em>; and maze length influenced the occurrence of SAB in both species. The number of …

Pteropod shell condition, locomotion, and long-term population trends in the context of ocean acidification and environmental change
… in shell condition (Clio pyramidata) or variability in shell condition that did not match expectations due to regional variability in ΩA (Limacina helicina). At locations with intermediate ΩA (1.5-2.5) the variability seen in L. helicina shell condition might be affected by food availability …

Effects of the Parasite <em>Microphallus turgidus</em> on the Predation, Swimming Endurance, and Activities of the Grass Shrimp <em>Palaemonetes pugio</em>
… parasites (>30) alters both the activity and swimming ability of infected grass shrimp, and as such alters its susceptibility to predation to mummichog fish, <em>Fundulus</em> <em>heteroclitus</em>. Uninfected grass shrimp were predicted to display longer swimming endurance, higher activity …

Bacterial adhesion in structured environments
… configuration to probe bacterial swimming behavior and surface attachment in their presence. We demonstrate that mucins maintain-and possibly enhance-swimming ability for E. coli and Pseudomonas aeruginosa, and show that they greatly reduce adhesion to underlying substrates. …

The effects of acid and water hardness on bluegill embryo-larvae determined by laboratory and on-site toxicity tests
… enhanced larval survival, and promoted hatchability. Hatching rates were decreased over those of the controls by 76 percent in soft water and by 23 percent in hard water at pH 4.0, and hatching was negligible at pH 3.8. The length of the hatching period was prolonged by 24 to 48 hours at pH …

Invasion Routes and Evolution of Brook Stickleback (Culaea inconstans) in Eastern Washington
… range into water bodies of variable habitat stability. Successful colonization by an invasive species is often influenced by flexibility in life-history traits. One important life-history trait is the number and timing of reproductive events, which can be driven by the stability of spawning …
