Contrast symmetric and asymmetric competition. How does the availability of soil nutrients shift the nature of competition from symmetric to asymmetric?
Using Chapter 6 (Sections 6.11 and 6.12 ) as your resource, what characteristics might enable a plant species (species 1 ) to tolerate low soil nutrient availability? How might these characteristics limit the maximum growth rates under high soil nutrient conditions? Conversely, what characteristics might enable a plant species \((\text {species } 2)\) to maintain high growth rates under high soil nutrient availability? How might these characteristics limit the plant species' ability to tolerate low soil nutrient conditions? Now predict the outcome of competition between species 1 and 2 in two plant communities, one with low soil nutrients and the other with abundant nutrients. Discuss in terms of tolerance and competition.
What is a trophic cascade?
What defines the fundamental niche of a species? How does this impact community structure?
