The number of tree species that occur in a hectare of equatorial rain forest in eastern Africa can exceed \(250 .\) In contrast, the number of tree species occurring in a hectare of tropical woodland in southern Africa rarely exceeds three. In which forest community (rain forest or woodland) do you think diffuse competition would be the most prevalent? Why?
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 defines the fundamental niche of a species? How does this impact community structure?
How does the structure of vegetation within a community influence the diversity of animal life?
