  • Coevolution: On The Origin Of Species

    between the species are similar, they are necessarily more complex. A prime example of this is the interaction between the limber pine (Pinus flexilis), the American red squirrel (Tamiasciurus hudsonicus), and the Clark 's nutcracker (Nucifraga columbiana). The interaction between these three species is complex, with selective pressures on each species affecting the others. The limber pine and the American red squirrel participate in a predator/prey interaction, with the red squirrel preying upon the seeds dropped by the limber pine. In reaction to this limber pine populations in areas with red squirrels developed larger cones, with more scales and fewer seeds (Benkman). In area where squirrels are absent limber pines produce cones smaller scales and twice as many seeds (Benkman). However, this also makes it more difficult for Clark’s nutcracker, the limber pines primary seed disperser, to harvest seeds. The relationship between the limber pine and the Clark’s nutcracker is mutualistic with each gaining benefit from the other. The relationship between the American red squirrel and Clark’s nutcracker is one of interspecific competition for the same resource, namely the pine seeds. Clark’s nutcrackers generally harvest seeds from cones before they drop from the tree, but when the American red squirrel is present, the selective pressure it exerts upon the cones decreases the nutcrackers’ effectiveness, resulting in a greater number of dropped cones(Benkman, Siepielski).…

  • Radiation Safety Research Paper

    To understand radiation safety, one must first be familiar with the term radiation. Simply put, radiation may be defined as energy traveling through space as waves or high speed particles. There are two types of radiation, ionizing and non-ionizing (e.g. Heat, visible light), they are differentiated by how they interact with matter. Non- ionizing radiation is essential to life, but excessive exposures can cause tissue damage. Ionizing radiation has sufficient energy to ionize atoms and…

  • John F Kennedy Ich Bin Ein Berliner Speech Analysis

    John F. Kennedy is very convincing in his speech as he has a strong ethos and pathos in his speech. This is for example due to his background. When the speech would have been held in the eastern part of berlin it would have been slightly different, it would for example probably have focussed more on giving people hope.
