  • Coevolution: On The Origin Of Species

    (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). This increases the viability for dispersal by scatter-hoarding rodents, though the area of dispersal is much smaller in comparison to the nutcracker (Benkman, Siepielski). This…

  • Gymnosperms Research Paper

    Not only, then, is an understanding of such relationships enlightening in terms of the so-called gymnosperm “persistence”, but also in regards to developing efficient conservation strategies. Roles in the ecosystem As mentioned previously, plant interactions allow for a greater understanding of the importance of a species in an ecosystem.
