ECOLOGY AND THE ENVIRONMENT (BIOL 354) – Fall 2018Connell (1978) Questions for DiscussionDescribe the equal chance hypothesis in your own words (2 pts)Explain why, according to the intermediate disturbance hypothesis, diversity declines when disturbance occurs too frequently or not frequently enough (2 pts)Describe the methods presented for testing the niche-diversification hypothesis, and the potential limitations (2 pts).Is it possible that more than one hypothesis is correct? Why? (2 pts)Describe how the intermediate hypothesis applies to coral reefs and tropical forests. (2 pts).What are other hypotheses for why there is greater diversity in tropical rainforests and coral reefs? (2 pts)Explain the importance of the “edges” of disturbance. How do the species on the edges contribute to recovery from a disturbance? (2 pts)Do you think Connell’s hypotheses apply to less diverse ecosystems such as the Arctic or deep ocean? Explain. (2 pts)Which of these hypotheses, if any, can be applied to motile (non-sessile) organisms? How would the ability to move affect the overall diversity? (2 pts). Write out the citation for this journal article using the format of the journal Ecology (2 pts).

Choose a 30 minute TV show geared towards children (for example a cartoon on the Nickelodeon Channel or Disney Channel). As you watch the episode, count the total number of commercials broadcasted within those thirty minutes as well as the number from that total that advertised junk food items*. Calculate the percentage of the junk food commercials shown (the number of junk food commercials divided by the total number of all commercials, and multiplied by 100). Now choose a 30 minute TV show geared toward an adult audience and complete the same counts (total number of commercials, number of junk food commercials, percentage of junk food commercials). Use your calculations to discuss your findings with your classmates in your initial response. Include the following in your discussion:The titles of shows you watchedDay and time of day each show was broadcastedYour calculated percentages and commercial trends (for example, many cereal ads or fast food chain ads, etc)Compare the percentages between the two shows and discuss your findings. For example, did you see any significant differences between the types of commercials shown during each TV show? Why do you think these differences exist? *Note: Junk food may include any food item with low nutritional value or high in carbohydrates and/or fats. (for example, Eggo waffles, high sugar cereals, candy, fast food items, desserts, yogurt drinks high in sugar, etc.)at least 250 words. please provide reference. Thank you.
