Shoaling and Movement in Fish

What is the resting metabolic rate?

• The energy required for maximum physical exertion

• The minimum energy needed for life

• The energy used during sleep

• The energy needed for digestion

Is there variation in resting metabolic rate among different species?

• No, it is constant across all species

• Yes, but it is not significant

• Yes, there is wide variation in resting metabolic rate across many species

• Variation only exists within a single species

Is the variation in resting metabolic rate repeatable?

• No, it changes every time it is measured

• Yes, but only in controlled environments

• Yes, the variation is repeatable

• It is repeatable but not significant

If Fish A and B are the same size, but Fish A needs 2.5 times more energy, what could be a potential effect on their behavioural ecology?

• No effect, as size is the only factor affecting behavioural ecology

• Fish A may engage in more energy-conserving behaviors

• Fish B will grow larger than Fish A

• Fish A will be more aggressive than Fish B

What does the yellow bracket in the diagram represent?

• Anaerobic capacity

• Standard metabolic rate

• Maximum metabolic rate

• Aerobic scope

Which metabolic trait is represented by the red bar in the diagram?

• Activity

• Digestion

• Growth

• Anaerobic capacity

What is indicated by the green bar in the diagram?

• Digestion

• Growth

• Stressor

• Activity

What is often linked to various behaviours such as aggression, dominance, boldness, and risk-taking?

• Genetic makeup

• Metabolic rate

• Social environment

• Learning and memory

Why are links between traits and behaviours important?

• They help in creating a hierarchical structure in populations.

• They are crucial for understanding the role of genetics in behaviour.

• They are important for understanding persistence of trait variability, correlated selection, and mechanistic effects of environmental stressors.

• They allow for the prediction of an individual's success in their environment.

What is the relationship between energy demand and behavioral traits?

• Energy demand causes a decrease in activity, boldness, exploration, and aggression.

• Energy demand is unrelated to activity, boldness, exploration, and aggression.

• Energy demand is a consequence of increased activity, boldness, exploration, and aggression.

• Energy demand leads to increased activity, boldness, exploration, and aggression.
