BIO 3176 Lecture Notes - Lecture 14: Frequency-Dependent Selection, Hemolymph, Game Theory
Document Summary
Hard to make equations when variables are different eg death vs energy expenditure. Feeding --> spend calories to get food, eat food to get calories. Behaviour not an all or nothing --> range. Different fitness costs deltabc is the difference between costs and benefits, for feeding it is calories. Phenotype z is maladaptive and will get weeded out. Adaptation = the greatest = x phenotype = selected for to the detriment of the other phenotype. Look at how it influences the survival rate and the amount of movement (energy spent to be in covey) Less of a dilution effect (camouflage by numbers) Conspicuousness (probably not though, but may cause increase in movement --> energy) Much of the survivorship is by energy --> getting food etc. Peak in the middle for survivorship and through for movement. A lot of food is from the sea. Fly up high and drop whelk to break the shell on rocky shore.
