Predation and this other process are hypothesized to explain the release of the chemical alarm signal schreckstoff in minnows.
Predation and this other process are hypothesized to explain the release of the chemical alarm signal schreckstoff in minnows. This process favors both Wilsonian and Hamiltonian spite. Populations with low rates of dispersal in which this process is thought to occur are termed "viscous." A trait with a perceptible phenotype, recognition of that trait, and this process happen in the green-beard effect. This phenomenon happens when (*) rb is greater than C via Hamilton's rule, meaning that the reproductive benefit of an action times the relatedness of the recipient to the actor outweighs the reproductive cost. For 10 points, name this altruistic behavior in which organisms enhance the reproductive success of their relatives.
