Chapter 54, Problem 10TYK
Ecologists survey the tree species in two forest plots. Plot 1 has six different species, and 95% of all trees belong to just one species. Plot 2 has five different species, each of which is represented by approximately 20% of the trees. Compared with plot 1, plot 2 has
- a. higher species richness.
- b. greater species diversity.
- c. lower species richness.
- d. Both b and c are correct.

A conservation biologist is studying a tropical rainforest and records the number of unique plant species in three separate patches within the rainforest. She finds that Patch A has 50 species, Patch B has 45 species, and Patch C has 55 species. She then determines that the total number of unique plant species across all three patches is 100.
Which type of diversity does this last number illustrate?
Group of answer choices:
A. Beta
B. Epsilon
C. Delta
D. Alpha
E. Gamma

- In a fragmented rainforest, researchers notice a change in plant species composition near the edges compared to the interior. What might be causing this shift? Group of answer choices: A. Lower temperatures at the edges supporting cold-tolerant plant species B. Increased light and wind exposure at the edges favoring the growth of sun-loving and wind-dispersed plant species C. Higher soil moisture at the edges leading to the proliferation of water-demanding plant species D. Increased competition for resources at the edges leading to a decline in plant diversityarrow_forwardMake a claim using evidence from this data about which vegetation type hosts the greatest diversity.arrow_forwardA conservation group has approached you to provide recommendations for purchasing land to help an endangered species and increase the overall biodiversity of a forest in a landscape that has been fragmented by agriculture. In the landscape, there are several medium to largefragments and a number of small fragments. Provide recommendations to the conservation group about where in the landscape they should devote their limited resources for a maximum impact. Justify your recommendations based on metapopulation dynamics of the endangered forest breeding species and island biogeographytheory (overall biodiversity).

- Which of the scenarios below illustrate(s) a trade off relating to functional diversity and life history traits? Select all that apply A- The C3 photosynthetic pathway is more energy efficient than C4 and CAM, but less water efficient. B-Plants that produce large seeds generally produce very few, while plants that produce small seeds generally produce many of them. C- Indices of species diversity rely both on species richness and species evenness, but not on species relatedness D- Endothermic animals are better able to maintain their preferred body temperature than ectothermic animals, but expend a large amount of metabolic energy to do so. E- Organisms that specialize on a single food source may use that resource more efficiently than generalists, but risk starvation if unable to find their particular food source.arrow_forwardNow think about the diversity index you calculated in the diversity and succession labs: a value calculated of 10 in Habitat A and 5 in Habitat B would indicate: Habitat A likely has higher species richness and lower species evenness than Habitat B Habitat A likely has lower species richness and lower species evenness than Habitat B Habitat A likely has higher species richness and higher species evenness than Habitat B Habitat A likely has higher species richness and the same species evenness as Habitat Barrow_forwardIn landscape ecology, the matrix is the area surrounding a habitat patch.
