Document Summary

Competition continued: we can use resource utilization curves to visualize competition s s e n t i. B: interference competition the species interact directly, the superior competitor exerts its superiority on the other species by direct interactions like aggression, threat of aggression, posturing etc. Interspecific killing occurred: two species of herbivorous squirrels. In a study population, 30% of female prairie dogs killed competing. Interspecific killing can occur as a result on interspecific competition: both exploitative and interference competition can occur at the same time, outcomes of competition, exclusion one species excludes the other from the area where they co-occur. If the primary dynamic is exploitative competition, the superior competitor"s numbers will increase, and the inferior competitor"s numbers will likely decrease potentially to the point of extirpation. Species b s s e n t i. *niche location stays the same, size becomes narrower to avoid overlap.
