Chapter 58, Problem 3CQ
Core Concept: Systems In the nutrient-poor heathlands of Europe, scotch heather (Calluna vulgaris) and cross-leaved heath (Erica tetralix) are gradually replaced by variegated purple moor grass (Molinia caerulea) and wavy hair grass (Deschampsia flexuosa). Adding C. vulgaris litter or nitrogen fertilizer to the soil speeds up this process. Explain this phenomenon, and identify which mechanism of succession is supported.

Answer Bank
Lichens can survive on bare rock surfaces where rooted plants cannot live.
The deep shade under mature heoch trees keeps birch tree seeds from sprouting.
The dense rocts of cogon grass outcompete other grasses for water and nutrients.
Plant rocts growing in cracks in bare ock assist with soil formation.
Nitrogen-fixing bacteria in alder roots increase the soil's nitrogen content.
Oaks can sprout and grow in the dim light under pines and birches.
A landslide exposes a bare rock surface. Initially, small, hardy pioneer plants colonize the area and contribute organic material to the developing soil. Which of the following examples demonstrates facilitation in ecological succession?
Group of answer choices
Larger plants establish themselves without any impact from the pioneer plants
Pioneer plants and larger plants interact to enhance the soil quality and support community development
Pioneer plants improve soil conditions, allowing for the establishment of larger plants
Pioneer plants outcompete larger plants for resources, preventing their establishment

- Agricultural systems typically represent a continuous early successional environment. You can think of it as a newly emerged island waiting to be colonized. This also brings implications for pest management and the species that can establish. What are the characteristics of early successional environments? Are we talking about primary or secondary succession? What are the characteristics of early successional plants? Which kinds do we expect to see in agricultural systems because of this reason? Based on the biodiversity within agricultural systems, what does this mean for insects and resulting pest management?arrow_forwardThe transition from freshwater to sea water creates unique biogeochemical properties found in estuaries. Describe some of the adaptations used by saltmarsh plants and mangroves to survive these conditionsarrow_forward12. Some plants need more light than others to survive. Knowing this, explain how the following factors might affect the type of plants that will start the process of secondary succession after an ecological disturbance. Then identify the factor that is probably the most important in determining which species will be the first to repopulate an area after an ecological disturbance. Explain your reasoning. a) the type of ecological disturbance (for example, a forest fire versus a fallen tree) b) the types of seeds left in the soil after the disturbance c) the availability of moisture in the soil d) the availability of nutrients in the soilarrow_forward
- Intraspecific competition is a competition between members of the same species and is commonly observed in crop plants. Table 6.2 shows the results of a greenhouse experiment which examined the effects of density on the germination and growth of barley. Plants were grown for two weeks in 10- cm diameter pots kept in identical environmental conditions and watered regularly. At the end of the experiment the plants were cropped by cutting the stems at the soil surface. In the given context, can you explain thoroughly the meaning of plant density that this passage is talking about?arrow_forwardEcologyarrow_forwardDiscuss the interrelationships between a coral reef, mangrove, and seagrass ecosystem.

(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.

- After a lava flow like seen below in Hawaii Volcanoes National Park, the beginning stage of primary succession begins with the non-vascular plants die and decompose to become the first soil on the previously bare rock. the root system of simple plants prevents erosion. the growth of non-vascular plants such as moss or lichen beginning to grow on bare rock. large gymnosperm and angiosperm develop which leads to shade tolerant plants being established.arrow_forwardPurple loosestrife (Lythrum salicaria) and musk thistle (Carduus nutans) are ruderal plants that are invasive to Colorado. Both species can inhabit a range of habitats, but they grow especially well in high temperatures and moist soils. L. salicaria also harbors nitrogen-fixing bacteria in its roots. Suppose a researcher investigated the type of community interaction that these species have with each other, in nitrogen-poor and nitrogen-rich soils. The researcher grew the two species of plants in artificially constructed plots, as follows:• Treatment 1: L. salicaria in nitrogen-rich soil• Treatment 2: L. salicaria in nitrogen-poor soil• Treatment 3: C. nutans in nitrogen-rich soil• Treatment 4: C. nutans in nitrogen-poor soil• Treatment 5: L. salicaria and C. nutans in nitrogen-rich soil• Treatment 6: L. salicaria and C. nutans in nitrogen-poor soil Plots contained a total of 10 plants (either all 10 of one species, or five of one species and five of…arrow_forwardPurple loosestrife (Lythrum salicaria) and musk thistle (Carduus nutans) are ruderal plants that are invasive to Colorado.
