Fоr the shоrt essаy pоrtion of the exаm, choose аny four of the following five prompts to answer. Be sure to indicate which prompt you are answering. We have seen some key examples now of invasive species, mostly in freshwater, and the costs of those species to society. First, describe two examples of freshwater invasives in water in North America. Next, provide some of the characteristics that make these invasives so successful at invading (and so hard to combat) and so costly to our society — what harm do they do to us and our systems? Then, describe in general terms what we know about their spread over the last decade or two. Next, describe the costs to human society of these invasives – you can give dollar value costs, but also think about how those dollars are used. Finally, describe briefly how invasives can change the ecosystems they invade. What do they do to the whole system? Coral reef distribution is dictated by a set of known factors reflecting much about the biology of the corals and their symbionts. Describe where reefs are generally found, the tolerances to environmental conditions, and what is required for the corals and their symbionts to be successful. What kinds of human or natural impacts can affect coral reef health? Discuss at least two human impacts and two natural impacts. Can human impacts have an indirect effect on natural impacts? Oysters have a long history of use, and we focused in class on the oyster industry in New York. From peaks of harvesting and production in the 1860s–1880s, oyster fisheries declined precipitously. What were the processes that led to the decline of oyster fishery in New York? Were declines synchronous (at the same time) in the Chesapeake Bay and if not, what is the trend in the Chesapeake over the last century? What is the general assessment of oyster health globally, and what are the signs of human responses to these problems? What are some other values for oysters beyond food value? Finally, describe some responses we are taking now to bring oysters back into New York Harbor. What are examples of the unanticipated consequences of domesticating and creating global economies for domesticated species in terms of the health of those species? One place where you should focus is bees and colony collapse disorders. First, explain the reason for broad-scale commercialization and global transport of bees around the world. How does this globalization of bee use support human well-being? Next, explain the key drivers of colony collapse, focusing on 2 of the most important of those drivers and how increasing the ability to keep bees and transport them has facilitated those drivers. Schistosomiasis is a major human health challenge. First, describe the phylogenetic position and life cycle of the animal responsible for Schistosomiasis. Next, briefly discuss how Schistosomiasis impacts human health worldwide. Finally, discuss how the development of dams in Africa has impacted rates and spread of Schistosomiasis. In doing so, describe exactly how dam building has had that impact, focusing on the trophic disruptions that dams can cause. Finally, discuss how humans can combat Schistosomiasis, focusing on key mechanisms to reduce the impact of the disease, especially in developing countries.
