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…

K-selected species typically a) have short life spans b) display a logistic graph c) are more competitive than r-selected species d) live close to the biotic potential, taking advantage of the environmental conditions
Explain Why bacteria do not cause food-borne illness until they are allowed to grow and increase their population density to a threshold number, like when being left out at room temperature for 12 hours or more. What happens as the bacteria grow in numbers? What do pathogenic bacteria synthesize? How do bacteria know what their population density is?
Which is true? a) communities may be contained within a population b) demes may be contained within a subpopulation c) populations may be contained within a neighborhood d) the biosphere may be contained wthin a deme e) all of the above are true
The Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States. There are now many success stories of animals/plants that were on the edge of extinction and now are returning. Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.
How are invasive species introduced into a new environment or ecosystem? Provide some examples of invasive species.
For Eicchornia crassipes (the Water hyacinth) which of the following is most correct: a. It has been successfully controlled outside its original natural range by the introduction of natural enemies b. It has no known natural enemies c. It has never been successfully controlled using natural biocontrol agents d. It is naturally controlled by many local enemies outside its original natural range
The Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River. One early study revealed that species on the river had absorbed pollutants from the water. Select the Pollutant Levels in Tissue, by Species dataset and follow the interactive to graph the data. Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm. The fish species with the highest level was about three times the value of the fish species with the lowest level.The fish species with the highest level was about three…
A new species of toad is introduced into a region in a shipment of fruit, survives, and manages to start breeding. How could you determine whether the toad was an invasive species? You would need to determine whether it started breeding with native species. You would have to see if it was present over a large region or if it stayed in one location. All nonnative species are invasive species. O You would need to watch over time to see if it had a negative effect on other species. As it is now breeding in the area, it would be considered native and not invasive.
Of the 50,000 species introduced into the United States, half are plants. Describe two ways in which non-native plants might be brought to a new environment. How might we help prevent non-native plants from establishing in new areas and posing threats to native communities?
