Metabolic rate, social status and life-history strategies in Atlantic salmon
Article Abstract:
A study was conducted to determine the relationship between metabolic rate and social status in the juvenile Atlantic salmon. The metabolic rate of freshly-hatched salmons were determined by measuring the rate of oxygen consumption. Feeding behavior, size and weight of juvenile and adult salmons were also compared. The dominance status was measured by observing the behavior of salmons during encounters with other salmons. The results showed that dominant salmons had higher metabolic rates and exhibited faster growth. This indicates that social status and life history in salmons are directly related.

Metabolic consequence of agonistic behavior: Crab fights in declining oxygen tensions
Article Abstract:
Shore crabs fight under a broad range of oxygen tension in their natural habitat. A study undertook to compare the metabolic consequences of fights at different oxygen levels, with those resulting from two extremes of activity not linked to fighting. Also studied was the duration of fights and pre-exposure to hypoxic conditions and whether this affects the duration and metabolic consequences of fights. It was found that ecological variables such as hypoxia have implications for the metabolic cost of agonistic behavior.

Patch choice and risk: Relative competitive ability is context dependent
Article Abstract:
Cichlids were examined to determine their relative abilities to obtain food under scramble competition. An individual's rank based on intake in one patch was uncorrelated with intake in the other path or intake in the single-patch trials, when provided with a choice between two patches. Some individuals spent longer in food patches and visited patches more often than others in the two-patch trials.
