please Describe the data in Figure 2.

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.
Based from the given table and graph, discuss the data and the relationship of the two factors (Mean wet biomass of plants (g) and Number of plants that germinated). Then, what is the effect of density to the Mean wet biomass of plants?
What do you mean by latitudinal gradient? What could be the possible reasons for diversity between tropic & temperate region?

(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.

Ernie notices that the plants in one greenhouses are smaller than the same species in the other greenhouses. Ernie's biology teacher says she has been having a problem recently with growing plants in this particular greenhouse. Ernie's lab group decides to investigate factors such as light levels, temperature, and soil nutrients in the three greenhouses. They find that these are the same for all the rooms. What additional factors would you suggest testing for, and how would each of these factors affect the growth of plants? 20arrow_forward
- Professor Lawrence Walker's research group experimentally examined the successional dynamics of a nitrogen-fixing shrub, tutu (Coriaria arborea) on a volcano in New Zealand. Tutu seedlings were found mostly in areas away from adult tutu shrubs, and only in areas with bare soil. Tutu thickets were not self-replacing. Tutu increased soil fertility by making soils ten times richer in nitrogen than soils without the tree. This enabled the late successional tree, kapuka (Griselinia littoralis), to colonize the habitat and replace tutu. The successional model that most best explains this process is the: facilitation model O inhibition model resistance model disturbance model resilience modelarrow_forwardBased on what you know about tropical forests versus temperateforests, why do you think temperate forest habitats are more suitablefor long-term agriculture, despite the fact that they have a shortergrowing season than tropical forests?arrow_forwardDuring the past 15 years, white-tailed deer populations in Canada have significantly affected woody plants in forest ecosystems. (a) To estimate white-tailed deer populations in four tracts of the Carolinian forest in southern Ontario, 185 white-tailed deer were captured and tagged with bands. After three weeks, 147 deer were recaptured and 26 had bands. Estimate the population size and show your calculations. (b) To further understand the impact of the deer populations on the woody plants, you decide to study the number of birch trees in an area 100 ha x 100 ha. Using a quadrate measuring 2 ha x 2 ha, you obtain the following results from four random counts: 16, 32, 27, and 11. Calculate the average population density and estimate the total population size of birch trees in the area. (c) Justify the decision to use the mark-recapture method for estimating the deer population size and the quadrat sampling method for the birch tree population.arrow_forward
- If only one half of the flora in the world existed in 2110 (perhaps due to deforestation), what do you predict the atmospheric carbon level would be ? How would you change the simulation to reflect this? What is the relationship between increased carbon in the ocean and increased carbon in the soil? How else might carbon be transferred to soil? Using the data generated by the simulation, determine the mathematical relationship between the percentage increase in fossil fuel consumption and the increase in atmospheric carbon. Is the relationship linear?arrow_forwardIf you compare species richness and evenness along the edge versus in the center of a tree farm and then make the same comparison for a rain forest, what would you expect to find? There would probably be a greater difference in richness but less difference in evenness between the tree farm and the rain forest. There would probably be a greater difference in evenness but less difference in richness between the tree farm and the rain forest. There would probably be about the same difference between the core and the edge in the tree farm versus the rain forest. There would probably be more difference between the core and the edge in the tree farm versus the rain forest. There would probably be less difference between the core and edge in the tree farm versus the rain forest.arrow_forwardwhich tree species was most abundant in your unpland community plot? which was most abundadnt in your lowland community plot ?arrow_forward
