The End Permian Mass Extinction Outline I. Introduction Think of a world which existed 290 million years ago. As you look out over the terran in front of you, you think that you are on an alien planet. You see volcanoes spewing ash and lava. Beside them is the ocean which is swarming with many different species of echinoderms, bryozoans and brachiopods. As you look down onto the sea floor you are amazed at the countless number of starfish and urchins. Some animals leave you can't even de

Leaf-cutting Ants Grant Erickson One of the most little known species of ants in North America is the leaf-cutter ant. This is mainly because it lives in tropical environments and it is not aggressive to animals or humans if not disturbed. The leaf cutting ant is a social insect. Alone the ant is virtually helpless but with the colony it can be a thing feared by animal and human alike. The leaf-cutting ants have a very important role in the tropical forest. They create and manipulate th

Sea Lamprey: A Great Lakes Invader Sea lampreys are aquatic vertebrates native to the Atlantic Ocean. Sea lampreys resemble eels, but unlike eels, they feed on large fish. They can live in both salt and fresh water. Sea lampreys, now found in all the Great Lakes, attach to fish with a sucking disk and sharp teeth. Sea lampreys feed on body fluids, often scarring and killing host fish. To control this destructive aquatic nuisance, state, federal, provincial and tribal agencies in both t

Although widely unknown to the American public, many of America's waterways are in extreme danger from something besides pollution. A new organism has been introduced that has the possibility to be deadlier than any pollution imaginable. This new threat is the zebra mussel (Dreissena polymorpha). A zebra mussel is a fresh water mussel that filters every bacteria in a water system until there is nothing left, including the zebra mussel. This can swiftly cripple any body of water. Z

Biological Warfare The history of Biological Warfare(BW), like most topics, can be divided into 3 parts: Early History, Modern History, and what we call "The Now." The early history starts as far back as you can think and continues up to the start of the 20th century. The first recorded use of biological agents is the Romans using dead animals to foul the enemies water supply. This had the dual effects of decreasing enemy numbers and lowering morale. The idea behind this kind of attack

The Prairie Dog Cynomys ludovicianus, known more commonly as the prairie dog, has more traditionally been viewed as the pariah of the prairie. However within the last year, attention has been drawn to these furry little rodents. They are extremely unpopular-¬Ěso much so that for decades the Federal Government has tried desperately to eliminate them. What the government doesn't know is that these creatures are vital to the survival and thriving of several species, and are in fact an asset t

Spinal Cord Regeneration Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that secondary injury is when the most critical damage occurs. This is when there is hemorrhaging in the gray

It is my opinion that Biometrics is an idea that should not become a reality due to the lack of privacy and control over our own lives that it would create. If the government were to carry out with the plan of Biometrics then the world would become more of a paranoid place then it already is. The general public would be able to be tracked at any moment and all the information about each individual would be accessible at the touch of a button. Our entire medical record
