Oryza 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 seeds per year 180 0.01 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? What are your predictions if leaf shape differences are genetic? 90 0.0 0.4

If the variation in flower-tube length in this population were due solely to environmental factors, what would be the expected change in flower-tube length over several generations? Why or why not?
In the following Fz population, we have the following data for plant height (cm) of individual plants: 3, 14, 15, 15, 16, 6, 6, 7, 7, 7, 7, 8, 8, 8, 9, 9, 10
The grassland ecosystem of Montana is being studied for its resilience as the population of its keystone species, the prairie dog, has declined in recent years. Four plots are established, two that still contain populations of prairie dogs and two that no longer have prairie dogs due to outbreaks of plague. A survey is done measuring the total number of producers (number of plants) and the diversity of producers (number of species) of each plot. The data are summarized in the table. Based on this data, which of the following correctly describes how the total number of plant and plant species will change over time in these plots? A - Plots 2 and 3 will show equal decline in plant and plant species due to the lack of a keystone species. B - Plots 1 and 4 will show a decline in plant and plant species due to an increase in the number of prairie dogs consuming the producers. C - Plots 2 and 3 will show a decline in plant and plant species, but plot 3 will show a slower decline due to a…
Seagrass meadows and vulnerable species in Pacific Islands and BahrainSeagrass meadows have profound impacts on sustaining vulnerable species such as dugongs and turtles. The aim of this assignment is to provide you three studies (two article and a chapter) dealing with seagrass in Pacific and Islands and Bahrain and the Arabian Gulf. Question: What are the differences between the populations of dugongs and turtles in both regions? -What are the main ecological goods and services provided by seagrasses in both regions based on the material, no-material and regulating services?
How is Myrica faya comparative in territory inclination to numerous other N fixers? For what reason do numerous N fixers have these territory inclinations? While considering Odum's model of environmental progression, how might Myrica faya adjust the successional direction? Make certain to reference one qualities from every one of the 6 classes depicted in Odum's Table 1 in your response.
Oaks in California are suffering from a phenomenon called sudden oak death (SOD). This has the potential to convert oak-dominated communities to communities made up of mostly grasses and smaller plants. How would this change the abundances of the tick species described in the article? Make a prediction for each of the three most abundant species, and describe the specific results in this article that justify your prediction.

These data were collected over a 5-year period for a perennial compass plant. What is the rate of growth of the population if the carrying capacity is 1000 (using 202 for starting population size)? What is the fastest rate of growth possible for this population?
Dissimilarity in plant community composition between 1982 and 1985 was larger than dissimilarity in plant community composition between 1985 and 2000. What does this tell you about the pace of succession in this location?
Suppose you were given the task of estimating the density of two plant species in a field. Based on the life histories of the two species, you expect that the spatial distribution of one of the species is approximately uniform, whereas the other is likely to be clumped. How might your approach to estimating the density of these two species differ?
Explain why a constant per capita rate of growth (r) for apopulation produces a curve that is J-shaped.
