Salmon: A Keystone Species

Submitted By
Words 246
Pages 1
Salmon are considered to be a keystone species in their respective ecosystems. They are one of the main food sources for bears and eagles. However over the years several species of Salmon have been killed almost to the point of extinction, now at only 10% of their historic numbers. The reason for this, deals most directly with overexploitation and dams. The average American consumes 2lb of Salmon yearly, which equates to about 637.8 million pounds of salmon being consumed in the United States alone. The freshwater in which salmon depend on is also rapidly disappearing at a level that makes spawning in their historic location difficult. Salmon are notorious for generation upon generations to return the same spot to spawn, and to be forced

Sea Lions

...Josh Hooley 12/4/14 Bio Issues Paper For my issues paper I am going to talk about the problems at Bonneville dam, with specifically the salmon munching Sea lions. Since 2002 Bonneville began to have sea lion sightings and at the time there were less than half a dozen of them so they were looked upon as a novelty. Something that was a surprise to see this animal at this particular location since they are native to the coast, a few years went by and the lions numbers increased. By 2004 there were over 100, so the biologists started to see a decrease in salmon numbers, so there started to be irritation instead of interest in the sea lions. This meant now that the people that were trying to increase fish numbers now had another rival, so a question started to be raised about the sea lions and what to do to get them out of the area. In 2008 there started to be rumblings about shooting a few of the animals, although they started with other things such as rubber bullets and empty shells. When this didn’t work they have now began shooting and to the present time there has been 70 confirmed kills, now leading to the question whether or not there should be regulated seasons. Last year research has shown that one third of the spring salmon didn’t make it past the dam, so now there is no doubt that the reason salmon numbers are down is due to the sea lions. So now it basically comes down to how many animals need to be taken out or do all of them need to go? In my...

Atlantic Salmon

...the study area. Based on the study, a variety of prey taxa were consumed over a broad size spectrum. Atlantic salmon was a top predator in the food web while capelin Mallotus villosus and amphipods Themisto sp. was primary consumer. Then, secondary consumer included boreoatlantic armhook squid Gonatus fabricii, sandlance Ammodytes sp., gadiforms, sculpin (Cottoidei), krill(Euphausiidae) and amphipods (Hyperiidae, Gammariidae, ) while phytoplankton is act as a producer in the food webs. Phytoplankton then was eaten by zooplankton. Based on the study, it shows that capelin and amphipod were the most component atlantic salmon diet which act as a top predator in the food web. After 1990, energy density of capelin was decreases. It decreases by 33.7% which altered the Northwest Atlantic ecosystem and Atlantic salmon productivity. The energy keeps loss through the trophic level by 10% from another to another trophic level. As a result, top predator, Atlantic salmon will get less and less energy. Less energy will affect the top consumer in the food web. This can affect the productivity of the ocean. Atlantic salmon growth and maturation depends on the quality and quantity of the...

Global Political Economy

...GRADUATE DIPLOMA IN INTERNATIONAL RELATIONS AND DIPLOMACY STUDENT GUIDELINE NOTES GLOBAL POLITICAL ECONOMY MODULE Paste the notes here… Political economy originally was the term for studying production, buying and selling, and their relations with law, custom, and government. Political economy originated in moral philosophy (e.g. Adam Smith was Professor of Moral Philosophy at the University of Glasgow), it developed in the 18th century as the study of the economies of states — polities, hence political economy. In late nineteenth century, the term "political economy" was generally replaced by the term economics, used by those seeking to place the study of economy upon mathematical and axiomatic bases, rather than the structural relationships of production and consumption (cf. marginalism, Alfred Marshall). History of the term Originally, political economy meant the study of the conditions under which production was organized in the nation-states. The phrase économie politique (translated in English as political economy) first appeared in France in 1615 with the well known book by Antoyne de Montchrétien: Traicté de l’oeconomie politique. French physiocrats, Adam Smith, David Ricardo and Karl Marx were some of the exponents of political economy. In 1805, Thomas Malthus became England's first professor of political economy, at the East India Company College, Haileybury, Hertfordshire. The world's first professorship in political economy was established...

Interpretation of Dreams

...The Interpretation of Dreams Sigmund Freud (1900) PREFACE TO THE THIRD EDITION Wheras there was a space of nine years between the first and second editions of this book, the need of a third edition was apparent when little more than a year had elapsed. I ought to be gratified by this change; but if I was unwilling previously to attribute the neglect of my work to its small value, I cannot take the interest which is now making its appearance as proof of its quality. The advance of scientific knowledge has not left The Interpretation of Dreams untouched. When I wrote this book in 1899 there was as yet no "sexual theory," and the analysis of the more complicated forms of the psychoneuroses was still in its infancy. The interpretation of dreams was intended as an expedient to facilitate the psychological analysis of the neuroses; but since then a profounder understanding of the neuroses has contributed towards the comprehension of the dream. The doctrine of dream-interpretation itself has evolved in a direction which was insufficiently emphasized in the first edition of this book. From my own experience, and the works of Stekel and other writers, [1] I have since learned to appreciate more accurately the significance of symbolism in dreams (or rather, in unconscious thought). In the course of years, a mass of data has accumulated which demands consideration. I have endeavored to deal with these innovations by interpolations in the text and footnotes. If these additions do...

She opened the drawer of the bedside table and carefully removed the gun. It was shiny black, and terrifyingly cold.
