Paramecium aurelia and P. bursaria occupy nearly identical niches. When grown together under conditions of bright light, P. bursaria tends to level off at higher population sizes than P. aurelia, but they continue to coexist. This observation superficially contradicts which of these concepts? A) Competitive exclusion principle B) Evolutionary adaptation C) Resource partitioning D) Character displacement

A typical grassland is inhabited by many species of plants which all live close to one another and use the same resources from the soil. One of the most important soil resources is nitrogen. Researchers have recently discovered that different types of plants prefer to absorb different forms of nitrogen from the soil (Ecology 87(5): 1244). Grasses absorb substantial amounts of ammonium, a nitrogen-containing compound, while small herb plants prefer to nitrate, a different nitrogen containing compound. With which of the following statements is an ecologist most likely to agree? A. The partitioning of nitrogen resources in the soil leads to reduced species diversity in the grassland because each type of plant only gets a fraction of the nitrogen as it needs.. B. The partitioning of nitrogen resources in the soil will eventually result in the extinction of many plant species in the grassland because they will not get enough food. C. All of the plant species would be just as successful if they were competing for nitrogen resources instead of partitioning them. D. The partitioning of nitrogen resources in the soil is likely to help an invasive plant species to become established in the grassland because the invasive plant species could use either ammonium or nitrate. E. The partitioning of nitrogen resources in the soil supports greater species diversity in the grassland because there are more niches.

In Lack's study of British passerine birds, different species seem to segregate based on resource factors, such as location of prey items. This differentiation among the niches of these passerine birds is known as a. competitive exclusion. b. intraspecific competition. c. character displacement. d. resource partitioning. e. allelopathy.
