- Explain the importance of pollinator constancy to the flower.
- Why is environmental filtering so crucial to community structure?
- What roles do competitive exclusion and character displacement play in community structure?
Step by step
Solved in 2 steps
- List three factors that are contributing to the decline of pollinator populationsWhat do the scattered dots represent in the forest tree community models? What other information can be extracted from the model? Describe the importance and limitations of the model.In response to warmer spring temperatures, a plant species is flowering earlier in the year than it would have historically. However, its primary pollinator, the bumblebee, has not been as responsive to temperature changes and continues to emerge at the same time as usual. As a result, peak floral displays have finished prior to pollinator emergence. This change in plant-pollinator interactions is an example of: a.Uncoupling of interdependent species b.Sympatric speciation c.Heterochrony d.Interspecific evolution

- You are responsible for adding plants to park to make it nice and green, and your only concem is making as much Net Primary Productivity (NPP) as possible. Your assistant has given you a list of potential plant combinations (Options A, B, C, D, or E) they believe might work. You DO NOT know the NPP of the individual plant species. Here is a table with your options. The number in each box represents the abundance (number of individuals) of that plant species for a specific option. Option A Option B Option C Option D Option E Species 1 0 20 0 20 57 Species 2 0 20 24 1 0 Species 3 120 20 24 10 0 Which option should you pick if you are trying to maximize NPP in your park? O A. Option A OB. Option B OC. Option C O D.Option D O E. Option E Species 4 0 20 24 10 17 Species 5 0 20 24 5 45 Species 6 02270 24 74Plants vary widely in how they allocate biomass to roots, leaves and stems. Two key measures of plant allocation in an ecosystem context are leaf area index (LAI) and the root to shoot ratio. a) Define each of these measures and discuss how variation in each measure can influence net primary production (NPP). b) Pick one of the measures and discuss how and why you would expect it to vary in relation to an abiotic factor of your choice. Underline the abiotic factor you choose.If some individual plants of a species consistently attracted one type of pollinator, while other individual plants of that same species consistently attracted a different type of pollinator, what could be the possible consequence?
