The Cost of Capturing Prey: Measuring Largemouth Bass Foraging Activity Using Glycolytic Enzymes (Lactate Dehydrogenase)
… gained to energy expended should be maximized. Activity costs associated with pursuit and capture are substantial and considered to be the most costly activity in free-swimming fish. Foraging behavior and fish activity have been linked to production of glycolytic (anaerobic) enzymes such as …

Effects of drifting prey abundance on food consumption and growth of brook trout in Shenandoah National Park
… to excess temperatures and increased metabolic costs. Purposes of this study were to quantify the relation between prey density and food consumption in brook trout, identify how diel feeding and prey size selectivity by brook trout affect the relation, and to determine if slow growth in the …

A Decision Support System for Advanced Composites Manufacturing Cost Estimation
… cost accounting methods, which distort costs by using inappropriate volume-based allocations of overhead. Activity-based costing has emerged as a methodology which provides more accurate allocation of costs to products or activities by their usage of company resources. Better designs may …

An activity-based cost model for design-concurrent calculation
… of a cost model that estimates the costs of product design alternatives during the design process. This cost information, regarding design alternatives, is for decision making purposes. With the help of this cost model, the designer can better approximate that product form which …

Modeling cost and time uncertainty in rail line construction
… is modeled bottom-up from the single activity to the entire rail line. Sub-networks of activities are combined in structure networks to model the rail line structures; in turn, the structure networks are organized in the construction network to represent the rail line. For the first …

How do human-induced environmental stressors shape the distribution, physiology, and behaviour of the Lemur leaf frog?
… needed regarding proximity to temperatures where activity costs may arise. In the behavioural trial, the introduction of a new plant into the species habitat resulted in reduced activity levels, avoidance of the modified area, and lasting changes in spatial preference for nocturnal activity even …

Factors Affecting Mercury Accumulation in South Dakota Fishes
… of prey, seasonal variation in prey use, and activity level appeared to strongly affect Hg burdens in walleye. Future studies exploring the relationship between prey types and activity costs, and potential effects on Hg accumulation are necessary to better understand Hg dynamics in …
