Summary Introduction
To hypothesize: The increased population density of a particular plant increases the rate at which a pathogenic
Introduction: “Population density” is the number of organisms inhabiting a particular area of land. An experiment should be carried out in a controlled environment where the test results won’t be impacted by external pressures. To carry out an experiment where the population density of the plant is detrimental to the result, various steps can be taken such as confining the plants in a specific area and so on.

Scenario: You have been hired by an electric utility company whose stockholders are really pressing the company on ESG matters (environmental, social, governance). The company owns thousands of acres of land surrounding one of its powerplants and leases much of this land to local farmers for agriculture. However, local environmental groups have been stating concerns in the local newspaper about the loss of insect biodiversity on in meadows surrounding the agricultural activities. You have been tasked by the company to develop an experiment to investigate whether a loss of insect biodiversity is occurring in these meadows because of these agricultural activities.
Action Steps:
Propose a coherent and testable hypothesis that captures some aspect of this concern.
Identify the independent and dependent variables in this experiment.
Identify any possible confounding variables that might influence your experiment.
Identify appropriate controls for your experiment.
Demonstrate how you…

The researchers interview people about how frequently they eat soybean products, where they eat them (at home or in restaurants), and during what time of day they eat them. The researchers also ask people about how they prepare soybean products, where they obtain soybean products, and any beliefs they might have about soybean products (such as their nutritional value). The data are used to assess the role of soybean products in the culture. The researchers are also considering how their findings relate to global soybean consumption patterns.arrow_forward.

Identify an interesting ecological or evolutionary research question, then design an experiment to address this question using a plant system. To come up with your research question, think of questions related to topics covered in lecture. The following questions are very general, but might give you some ideas as you develop your own, more specific, question.• Which species in a group of species is the best intraspecific competitor?• Which species in a group of species is the best interspecific competitor? • Is the best intraspecific competitor also the best interspecific competitor?• Does competitive exclusion occur between two species with similar ecological niches?• Does the outcome of interspecific competition change in different environments, or is the best competitor always the best competitor under all environmental conditions?• Similar to the question above –…arrow_forward
- Imagine you are performing an experiment on the growth of aspen seedlings under different temperature conditions to better understand how aspen forests may be impacted by changes to the climate. In your experiment, aspen seedlings are grown in a temperature controlled greenhouse at either 20° C or 30° C. Seedlings are measured for height and number of new leaves on a weekly basis. Your hypotheses are as follows: Alternative hypothesis: Temperature influences how quickly aspen seedlings grow. Null hypothesis: Temperature has no impact on how quickly aspen seedlings grow. You perform a t-test to compare the average weekly growth for seedlings in the 20° C treatment versus the 30° C treatment. You get a p-value of 0.03. How likely is it that the difference between the two averages was due to random chance?
