The effects of temperature on the physiology and locomotory behavior of the American lobster, Homarus americanus
… that could place the lobster outside of its aerobic scope.</p><p>Activity levels were monitored in juvenile lobsters under both light and dark conditions over a range of ambient temperature conditions from 2.5--17.8°C. Lobsters traveled significantly farther in the dark than in the light …

RELATING METABOLIC PHENOTYPES TO MOVEMENT BEHAVIOR IN BROOK TROUT
… moved over 250m displayed a significantly larger aerobic scope than individuals that moved less than 250m. Temperature effects on metabolic measures were not detected among the brook trout in this study, but this could be due to wild acclimation to a range of temperatures rather than a single …

Hummingbird Hovering Energetics and Flight Capacities Across Elevational Gradients
… metabolic input, while at the same time aerobic metabolism is constrained by hypoxic conditions associated with increasing elevation. These limits may restrict the range of behaviours that can be aerobically sustained. This thesis explores the kinematic and aerobic capacities for exercise …

Understanding the Mechanisms that Determine Feed Conversion Ratio in Chinook Salmon – Physiological and Behavioural Aspects
… with respect to maximum metabolic rate (MMR) or aerobic scope (AS). The minimal resting metabolic rate (RMRmin) varied between FCR phenotypes in Chinook salmon reared in saltwater but not in freshwater. Specific dynamic action was measured only in freshwater fish and did not differ between …

Evaluating metabolic rate, survival, feeding behavior and energetic demand in two genotypes of Apis mellifera
… metabolic rate, maximum metabolic rate, and aerobic scope. Workers of the two genotypes were provided either low (20%) or high (40%) sucrose diet treatments in a controlled laboratory environment, and then their metabolic rates were measured. Survival over 24 hours of the two genotypes was …

Influence of parental swimming stamina on the cardiac and metabolic performance of larval zebrafish (Danio rerio).
… 21dpf, and cost of transport (COT) and factorial aerobic scope were derived from oxygen consumption measurements. Routine heart rate at 2dpf of LSL was 164 ± 1 b·min-1, compared to only 125 ± 2 b·min-1 for HSL. Routine heart rate subsequently peaked at 203 ± 1 b·min-1 at 5dpf in the HSL group, …

The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)
… temperature on two measurements of whole-animal aerobic performance: aerobic scope and critical swimming speed. I chose to use two species of fish that use distinct reproductive characteristics, the fall spawning Lake Whitefish and the spring spawning Yellow Perch. I hypothesized that …

The role of intrinsic and extrinsic factors in shaping alternative migratory tactics and metabolic phenotypes in brown trout
… fish, while SMR, maximum metabolic rate, and aerobic scope (AS) were higher in offspring from a naturally anadromous population compared to a non-anadromous population. Population-specific effects of food restriction on AS also emerged. I further addressed the causes and consequences of …

Physiological and behavioral drivers of angling vulnerability in freshwater sportfish
… metabolic rate, maximum metabolic rate, and aerobic scope) and stress responsiveness in driving angling vulnerability. A set of largemouth bass from a suite of lines selected for differing vulnerability to angling were assessed for boldness in a standard open-field test. Following this, …

Effects of environmental warming on lentic freshwater communities and the behavioral and physiological responses by fishes to warming
… altering physiological processes that preserve aerobic scope and that these changes are generationally transient, but that changes in maximum thermal tolerance in response to warming is limited to phenotypic plasticity. Overall, I found that power plant cooling lakes are viable study systems to …
