Chapter 12.8, Problem 2MC
Summary Introduction

To draw:

A graph that would be formed if the information from the second half of the experiment is added to the graph of fig: 12.22a “over four generations, the average fish in the large-harvested population weighted much less than those in the small-harvested populations” of chapter 12 “the evolution of life” given in the textbook.

Concept Introduction:

David Conover and Stephan Munch are fish ecologists who studied on small coastal fish (Atlantic silverside) tested on the above predictions. They took a large enslaved population of coastal silversides and randomly divided them into six tanks. Each tank contained approximately juveniles. After six months, they took two tanks for the treatment that are as follows:

  • Large-scale harvested: In this treatment, the 90% fish were removed from the tank and 10% smallest fish remained.
  • Small-scale harvested: In this step, 90% smallest fish were removed.
  • Random-harvested: In this step, 90% fish were removed without any size consideration.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
