Changing conditions put intense pressure on organisms-some of which become extinct. For example,
of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the
technologies that may allow bringing back organisms that have become extinct. This brings up ethical
questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do.
Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of
resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct
species is very difficult to determine, the researchers decided instead to look at the cost of
reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers
considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within
the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…
A conservation biologist has been asked to explain why it is important to protect biodiversity. She would list all of the following reasons except for which one?
A. Humans are dependent on many species for food, medicines, fiber, and other necessities.
B. Biodiversity can be exploited indefinitely for the profit of humans.
C. Other species have inherent value and humans have a moral obligation to protect them.
D. Biodiverse ecosystems provide ecosystem services that sustain all life on Earth.
E. Biodiversity provides emotional and physical health benefits by providing places for humans to visit for wonder, insight, and exercise.
Which of the scenarios below illustrate(s) a trade off relating to functional diversity and life history traits? Select all that apply
A- The C3 photosynthetic pathway is more energy efficient than C4 and CAM, but less water efficient.
B-Plants that produce large seeds generally produce very few, while plants that produce small seeds generally produce many of them.
C- Indices of species diversity rely both on species richness and species evenness, but not on species relatedness
D- Endothermic animals are better able to maintain their preferred body temperature than ectothermic animals, but expend a large amount of metabolic energy to do so.
E- Organisms that specialize on a single food source may use that resource more efficiently than generalists, but risk starvation if unable to find their particular food source.

- 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.

Scientists' efforts to monitor and protect biodiversity are being aided by a slew of new technologies and the volunteer work of ordinary citizens. To help scientists in their conservation work, new technologies have been developed. For example, Footprint identification technique (FIT) uses photo digitization to identify the footprints of large cats and other mammals, which will allow collection of data about these animals in a noninvasive manner. Other noninvasive data collection techniques include vocalization identification, drones, DNA analysis, and camera-trapping. Apps such as eBird and iNaturalist allow amateurs to record their observations in open-access online databases for further analysis. Smartphones and drones could be useful in collecting data to prevent poaching, although such technologies are in their infancy and still not widely available in developing countries. Remote sensing could be used to monitor changes in…arrow_forward
