population in valleys, young aspen shoots were not treaded or eaten and grew. Wolves, changing the habitat usage of ungulates, affect biogeochemical dynamics (Frank 2008). Frank noted ungulates, including elk, bison (Bison bison), and pronghorn (Antilocapra americana) in Yellowstone migrate each year from low elevation winter range to high elevation summer range. During this migration, ungulates feed on young forage and prevent sprouts from reaching adulthood. A study conducted by Frank sampled grassland sites during periods of ungulate migration that resulted in decreased grassland consumption from 1998-1999 to 1999-2001 (2008), showing a decline in herbivory. Aspen (Populus tremuloides) are the most discussed tree recovered in Yellowstone, but other species were also recruited. Cottonwood (Populus spp.) and young willow (Salix sp.) began to grow for the first time in decades (Beschta and Ripple 2010). According to Beschata and Ripple, this tree growth is due to a tri-level trophic cascade, consisting of wolves, ungulates, and vegetation (2010). Without proper tree growth, soil was unable to be kept in place and caused disaster, for there was annual flooding of the Lamar River that washed away soils (Beschta 2007). Ripple and Larsen looked further into the lack of growth and discovered the aspens’ tree rings stopped forming almost immediately after gray wolves were removed from Yellowstone. In another study of the Gallatin elk winter range in Montana, aspen stems were…

studies. Scientific studies show that although wolves had been introduced back into Yellowstone park, elk were not afraid enough to change their eating habits. For example, a study published in the journal Ecology in 2010 found that “aspen trees hadn’t regrown despite a 60 percent decline in elk numbers.” This shows that even in areas where wolves killed the most elk, the elk weren’t scared enough to stop eating aspens. The wolves being reintroduced into Yellowstone did not cause the aspen…

For the reactive flash volatilization (RFV) process based on the knowledge that the catalyst bed is preheated to high temperature, pyrolysis of the heated cellulose particles on the surface of the bed is expected to be fast enough that it will not be a rate-limiting step. Hence, the kinetics of the RFV of cellulose reduces to gasification of the produced volatile organic compounds (VOCs) on and in the catalyst bed. To represent the RFV of the VOCs from flash pyrolysis of cellulose, Aspen Plus…

The Quaking aspen (Populus tremuloides) is a very abundant tree in the mountainous regions here in Utah. Moreover, this particular species of tree is very popular because it grows most commonly around burn sites. After a natural disaster the Quaking aspen is usually one of the first trees to take root. The Quaking aspen is well known here because of this, however the common person may find it hard to identify when an aspen tree is not healthy. Sooty bark canker (encoelia pruinosa) is a canker is…

Title A4 Aspen Balzly Introduction: Upon entering a farmer’s market, one might assume that consumers are eager to hand over their money to anyone with the product or service that they are in search of. Buyers, however, have come to prove that they can be very picky and know exactly what they want and how they want it. Booths of all sorts are located directly next to their competitors, each striving to catch the buyer’s interest and suede them into purchasing their product.…

unknown situations can appear to be scary, when in reality we just have to put ourselves out there and experience whatever we can. Mary Louise Pratt once spoke of contact zones, saying that “The idea of the contact zone is intended in part to contrast with ideas of community that underlie much of the thinking about language, communication, and culture that gets done in the academy.” Pratt is portraying the idea that contact zones are cultures clashing together and sometimes through…

Build on Staff Buy in No matter how old you are, change can be stressful. Adjusting to new ideas often begins with resistance and before confidence in its worthiness is achieved, there is often anxiety and frustration. But in the end, change is growth.

The two main themes of the book The Selection by Kiera Cass are The beauty of simplicity and being able to deal with the choices that life gives you. Throughout the book, America Singer is always asking for the most simple things, this is relative to the theme of finding beauty in simplicity. On page 90, America Singer is getting a make over, although all of the other girls are having their hair dyed and cut, America denies anything that would make her not look herself. America ends up having…
