Chapter 55, Problem 5Q
Summary Introduction
To review:
A multiyear study that could provide more accurate information about the absence or the presence of the timing mismatches between the plant flowering and the insect pollinators emergence.
Introduction:
The insects that pollinate the flowering plants have a mutual relation with such plants. The plants provide nectar and the insects help the plants in pollination. The emergence of the insect pollinators is closely related to the flowering of plants, which occur during the month of April, in North America. A study was conducted to examine the close association of these pollinators and the plant flowering by considering 10 bee species across North America. However, climate warming might indicate a slight mismatch between insect emergence and the flowering in plants.

Clausen and colleagues proposed two hypotheses to explainthis variation within a species: (1) There are genetic differencesbetween populations of plants found at different elevations.(2) The species has developmental flexibility and can assumetall or short growth forms, depending on local abiotic factors.If you had seeds from yarrow plants found at low and highelevations, how would you test these hypotheses?
please Describe the data in Figure 2.
Figure 2. Pre-dawn and midday leaf water potential (Ψleaf) for the two species at different dates throughout the year.
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.
Explain why knowledge of the effects in density is important to the crop farmer.

Then, what is the effect of density to the Mean wet biomass of plants?arrow_forwardMany plants mimic other plants or other animals in order to attract pollinators. a) Describe one example of plants mimicking either other plants or other animals in order to attract pollinators. b) Why might these “cheating” strategies have evolved rather than developing “truthful” signals to attract a pollinator?arrow_forwardOryza rufipogon is the wild relative of cultivated rice. In its native SE Asia, annual and perennial populations can be found. Annual populations typically grow in aquatic habitats that dry out seasonally, while perennials typically grow in more permanent aquatic habitats. In their respective habitats, annuals produce narrower leaves than perennials. An experiment was conducted where annual and perennial seeds were grown together in a permanent aquatic habitat and demographic data on survival and fecundity were collected. The data are below: Annual seeds 1st year survival 0.01 0.01 seeds per year 180 90 Edit View Insert Format Tools Table Adult survival rate Perennial seeds What additional data would you need to collect from this experiment to determine whether the differences in leaf shape described above have a genetic basis or are induced by the environment?
