Pliocene

evolved from an incredibly diverse and interesting history. Geographically, Panama lies on an isthmus, a strip of land that essentially connects the greater landmasses of North and South America. It is believed that volcanic activity in the late Pliocene era closed the former Central American Seaway that had separated the two continents. The climatic implications of this landform are incredible, allowing for the redistribution of oceanic currents and the formation of the Gulf Stream of the Atlantic

Yetter, Drew J., Cook Inlet Basin Location and Extent: The Cook Inlet Basin is located in the south central part of Alaska, and stretches roughly 180 miles from the Gulf of Alaska to Anchorage. (Figure 1) This basin includes Susitna and Copper River basins in the north and the Shelikov Straight to the southwest. The watershed of this inlet covers around 100,000 km2 in southern Alaska, east of the Aleutian Mountain Range, receiving water from four main tributaries, the Knit, Little Susitna, Susitna

Introduction Rapid population growth in South Florida has significantly increased the demand for water and the strain on the fresh groundwater supplies has triggered more saltwater intrusion to the Biscayne aquifer. Saltwater intrusion has been one the main contaminant that continues to endanger the Biscayne aquifer. It has occurred as a result of the followings: the over-pumping by wells, the construction of drainage canals, and the lowering of the water table by drought. Ongoing efforts by South

In 1986, it was realized that drastic measures would be needed if humans were going to save the California condor form extinction. With only three males remaining in the wild and 22 others left in captivity, an aggressive approach was necessary to save these majestic birds. Standing at nearly 5 feet tall, weighing up to 31 lbs and with a wingspan of up to 10 feet, the California condor (Gymnogyps californianus) is one of the largest flying birds in Northern America. Surpassed only in weight and

Global warming and global climate change has been a consistent news headline and global topic for the past two decades. From a political standpoint, there has been great debate as to whether or not humans are completely to blame, partially to blame, or to blame at all for the changes we are seeing in the Earth’s climate. However, from a scientific perspective, this is not the case. From the Kyoto Protocol, to dummy-downed explanation like in Al Gore’s “An Inconvenient Truth”, to NASA’s comprehensive

The debate of human evolution being fact or fiction has been around for hundreds of years. Evidence of human ancestry has been found in many parts of the world and these fossils found have been proven to be human. The parts of the world include Eurasia and Africa. Although fossils are found in Eurasia, the human ancestor the Hominoidea has been traced back to the Miocene epochs, which were 23 to 5 million years ago. The Hominoidea is a super-family, which contains many species that are existent today

The likelihoods surrounding the controversial issue of global warming have caught the attention of the world; however, a new concern about what steps we are doing to deal with it is being reviewed and sensibly evaluated. This has generated the idea that a variety of simple more practical ideas should be considered. After conducting my own survey, I found that the approximately 53% are not only worried about global warming, they are also generally uninformed and claim to be unsure about what they

(McDowall, 2012). At least 25 species of endemic galaxid and mudfish have been identified, making Galaxiidae the largest taxonomic group of freshwater fish in New Zealand (McDowall, 2012), and fossil records show they have remained unchanged since the Pliocene (McDowall, 1976). Galaxiidae are only found in the Southern Hemisphere, and they have been observed living in and around New Zealand, Australia, South America and South Africa (McDowall & Frankenberg, 1981). McDowall, a notable authority on Galaxiidae

Introduction: ¬Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces

As humans evolve, they will change. Through the years, humans will both change mentally and physically. Through research and reasoning, people can only predict what might be the next human evolution. Much of what is predicted is based on the world that humans live in today. Some day, humans might be even be able to change their own genetics as science and technology advances. Ideas of Evolution- Evolution represents the biological timeline between all living things around the world. This idea
