Mountain Pine Beetle Analysis

1557 Words7 Pages

Over the past two decades the pine forests of Western North America have experienced major changes due to the Mountain Pine Beetle epidemic that began in 1995. Mountain Pine Beetles are insect parasites that use trees as their hosts in order to mate and lay eggs. After the larva becomes a beetle, the tree is killed and the next generation of beetles set out to find another pine tree and the cycle repeats. Environmentalists have proven the changes in the lifecycle of the pine beetle to be directly correlated with the adaptations of the Mountain Pine and climate change. Since the epidemic began the Mountain Pine Beetle is responsible for affecting millions of acres of forest in the western United States and over 44 million acres in British Columbia. (Rosner 2015) The impact that the Mountain …show more content…

Environmental scientists at Colorado State University found that Mountain Pine beetles are now able to produce twice as fast. The spring seasons are now warm enough for the pine beetle to leave their previous host and find a new one to mate inside of. Mid-way through the summer the beetle hatches and the cycle repeats again and another set of eggs are laid for the winter. This means that one summer can witness the life and death of two generations of Mountain Pine Beetles and thus killing twice as many trees in one year. (CSU, 2015) The Mountain Pine Beetle epidemic has shown the direct impacts of the warming of our planet and further proves the science behind climate change. The Mountain Pine Beetle now poses as another threat to the forests of North America and our environment. The pine beetle issue is much deeper than just having dead trees. The impacts the epidemic has had since 1995 has changed the landscape of Western North America forever and it greatly impacts communities, national forests, public lands, private lands, the lumber industry and water qualities in the

The original bean which is the black eye peas is where the beetles grew up on for many generations so they are successful and familiar with supported that the beetles would lay majority of their eggs on the Northern beans because the northern beans are close to what the bean beetles originated from, but as we analyzed the data it also showed that the bean beetled laid most of their beans on the Navy beans as well.

1077 Words | 5 Pages

Noted for her prominence in a number of Colorado’s climbing associations, Agnes Vaille was the first woman to successfully scale the east face of Longs Peak, which ultimately cost her her life.

Kiener’s tale reminisces the harrowing nature of Vaille’s death on Longs Peak and the struggle to retrieve her frozen body, which resulted in the death of Herbert Sortland, the caretaker at the Longs Peak Inn. However traumatic this story, Hewes had chosen not to include it in his autobiographical journal that was published six years after her death. Detailed in Pickering’s report is the recovery of Kiener’s story, the nature of Vaille’s death, and who was responsible for Vaille and Sortland’s deaths, as well as the controversies surrounding each issue.

From Krakauer’s letter to the reader, we have a basic understanding of his immense personal grief as the result of a tragedy on Mount Everest and the reason for writing the book. Then instead of jumping right into the narrative from the very beginning, Krakauer starts in the middle– the time and day when he reached the peak of Mount Everest and returned, and how eight others couldn’t do the same. This interlude first shocked me but also prepared me for what was to come. Most are unaware of what occurs at Mount Everest but this book awakens those who are oblivious, including myself. The book was incredibly informative, starting right from the beginning when the author gives the complete history of those attempting to reach the top of the world.

The Beetle Gender

1149 Words | 5 Pages

The Beetle, an 1897 novel by Richard Marsh, takes place in the dark and supernatural country of Egypt, where said creature of horror is believed to change its form at will, and use its hypnotic powers to prey upon young middle-class English people. The novel appears to, more often than not, deal with society’s anxiety surrounding the turn of the century. Marsh analyses the opposing views of sexuality and femininity through the exchange of sexual manipulation in the novel. By numerous means of sexually influenced interferences, and the degenerate figure of the colonized, The Beetle builds a sort of parallel between the practices of the British Empire, allowing the British characters to see their individual wrongdoings in a horrific other form.

The average of the three trials revealed that 0.67 out of 8 patterned caterpillars had been pecked and 2.67 out of 8 of the solid colored caterpillars showed signs of avian predation (Figure 1).
