Osage Orange (Maclura pomifera)
[ send me this paper ]
A 12 page overview of the species, its characteristics, and its ecological niche. This paper emphasizes that not only is the species attractive enough to make it one of the more desirable landscaping plants, it has been used throughout history for purposes as diverse as bow and arrow construction, to use as living fence poles, to phytoremediation. While the species is native to North America, it is not native to all regions of North America even though it has been introduced there. Ironically the same qualities which made it desirable for various anthropomorphic interests have resulted in the plant being spread into areas in which it is now considered an invasive exotic. Bibliography lists 14 sources.

Overfishing, Sharks, and Biodiversity
[ send me this paper ]
An 8 page overview of the impacts of overfishing on sharks and other species, some of which might not be immediately obvious as to their relation with the shark. Emphasizes that our oceans are fascinating testaments to the complexity and interrelationships of living organisms, that they are comprised of a number of interrelated components, each with its own ecological value. Details possible impacts to both open water diversity and coral reef biodiversity as a result of the overfishing of sharks. Bibliography lists 8 sources.

Philodendrons: Environmental Considerations and Care
[ send me this paper ]
An 8 page overview of the considerations which must be made when growing Philodendron. Devotes considerable attention to growth preferences and the physiological reasons behind those preferences. Concludes that while Philodendrons are among the easiest of houseplants to grow, attention must be paid to the type of soil that they are planted in, the presence of absence of surfaces upon which the vine can trail, appropriate soil water levels and humidity, and the provision of a clean environment which discourages pests. Bibliography lists 14 sources.

Pneumonia
[ send me this paper ]
A 3 page overview of pneumonia. Pneumonia can be caused by a variety of factors. These include both bacterial and viral organisms. The epidemiology of each of these organisms vary as does the specifics of the treatment regime. One of the most important aspects of dealing with pneumonia is prevention. Prevention is especially important for community acquired pneumonia. Effective prevention requires accurate diagnosis of the cases that do exist, isolation of infected patients, and strict attention to hygiene both by the patient and by those that move between patients. While antibiotics can be used to treat bacterial pneumonia, treatment for viral pneumonia is normally supportive in nature. Bibliography lists 3 sources.
