SCIENTIFIC INQUIRY
An ecologist studying plants in the desert per1ormed the following experiment. She staked out two identical plots, containing sagebrush plants and small annual wildflowers. She found the same five wildflower species in roughly equal numbers on both plots. She then enclosed one of the plots with a fence to keep out kangaroo rats, the most common grain-eaters of the area. After two years four of the wildflower species were no longer present in the fenced plot but one species had increased drastically. The control plot had not changed in species diversity. Using the principles of community ecology, propose a hypothesis to explain her results. What additional evidence would support your hypothesis?

An ecologist studying plants in the desert performed the following experiment. She staked out two identical plots, which included a few sagebrush plants and numerous small, annual wildflowers. She found the same five wildflower species in roughly equal numbers on both plots. She then enclosed one of the plots with a fence to keep out kangaroo rats, the most common grain-eaters of the area. After two years, to her surprise, four of the wildflower species were no longer present in the fenced plot, but one species had increased dramatically. The control plot had not changed. Using the principles of ecology, propose a hypothesis to explain her results. What additional evidence would support your hypothesis?
An ecologist studying desert plants performed the following experiment. She staked out two identical plots that included a few sagebrush plants and numerous small annual wildflowers. She found the same five wildflower species in similar numbers in both plots. Then she enclosed one of the plots with a fence to keep out kangaroo rats, the most common herbivores in the area. After two years, four species of wildflowers were no longer present in the fenced plot, but one wildflower species had increased dramatically. The unfenced control plot had not changed significantly in species composition. Using the concepts discussed in the chapter, what do you think happened?

- Figure 47.6 Scientists measured the relative abundance ot fern spores above and below the K-Pg boundary in this reck sample. Which of the following statements most likely represents their findings? An abundance of fern spores from several species was found below the K-Pg boundary, but none was found above. An abundance of fern spores from several species was found above the K-Pg boundary, but none was found below. An abundance of fern spores was found both above and below the K-Pg boundary, but only one species was found below the boundary , and many species were found above the boundary. Many species of fern spores were found both above and below the boundary, but the total number of spores was greater below the boundary.arrow_forwardFigure 21.6 The Svalbard seed vault is located on Spitsbergen island in Norway, which has an arctic climate.

The graph above shows how seed production in a plant species varied with population density in an unfrag- mented habitat (site A) and in a fragmented habitat (site B). Which of the following conclusions is best supported by the data? (A) There is no relationship between seed production and habitat fragmentation. (B) Seed production is higher in dense populations. (C) Seed production is lower in dense populations. (D) Habitat fragmentation has more effect on seed production than does population density. (E) Pollinators are either less abundant or less effective in small populations.

(FYI: Alnus is alder, Salix is willow, Picea is spruce) Each line describes the average change of plant species richness through time in those plots. For each of the dominant species in those plots, determine whether they facilitate, inhibit or have no effect on species richness in late successional stages.
