The mountain pine beetle epidemic is causing environmental and social impacts to much of British Columbia. Our forests are very important and will no longer be able to maintain their role if changes are not made. The devastation has had a sweeping impact on B.C.’s ecological, and economical well-being. Additionally, recent studies are drawing attention to the carbon-emitting properties of the dead forests, which is a global concern. A popular misconception developed that the current provincial mountain pine beetle epidemic began in Tweedsmuir Provincial Park.
The church lost man power and impoverishment through not being able to cultivate their vast tracts of land. Many important people including a medieval doctor, Ibn-al–Wardis, and a philosopher named, Gental-da-Foligna died while studying the ways to cure Black Plague. The plague also affected agriculture because their was few peasants to tend to the fields because they were dying and the few left wanted more money because they were doing more work. Next there were many worries and responsibilities during the Black plague. The main way the plague was spread was from person-to-person and breathing on someone.
But this was hard to believe, as the island was full of food. Maybe the cause of death was drought. Scientists have discovered that the worst drought in many years was between 1604 and 1609. They can tell this because of the tree samples that have been taken. No water meant that crops wouldn't grow, and animals would die, as well as humans.
pestis—is generally believed to be the cause of the Black Death that swept through Europe in the 14th century and killed an estimated 25 million people, or 30–60% of the European population. Because the plague killed so many of the working population, wages rose and some historians have seen this as a turning point in European economic development. The signs and symptoms of bubonic plague. The most infamous symptom of bubonic plague is an infection of the lymph glands (lymphadenitis), which become swollen and painful and are known as buboes. After being transmitted via the bite of an infected flea the Y. pestis bacteria become localized in inflamed lymph where they begin to colonize and reproduce.
Bush Honeysuckles Bush Honeysuckles are inavasive species plants that grow quickly and agressivly diplacing other Plants. Bush Honeysuckles are harmful to plants, mammals, and wildlife. Of the roughly 2,300 inavasive plant species in Indiana, 25% are non native and are responsible for degrading and destroying thousands of acres of our natural plant communities of Indiana. Bush Honeysuckles where introduced to Northern America in late 1800s and 1900s. They are now reported to be found in 81 counties in Indiana.
Marissa Ojeda Mr. P. Falk Honors Biology Period 1 22 September 2011 Invasive Species Paper In 1935, three thousand cane toads were released in sugar plantations in the northern part of Queensland, Australia. The cane toads were released to control the beetle population that was damaging the sugar cane crops. “Unfortunately, the Cane Toad did not control the insects and went on to become one of Australia’s most highly invasive species, currently occupying over 500,000km² of Australian mainland, with densities reaching up to 2,000 toads per hectare when Cane Toads first colonize a new area”¬(Exotic Animals 1). The government is trying to eradicate the cane toads, which are considered pests, by asking all who find them to collect them and dispose of them. The cane toads should be eradicated because of its negative impacts towards the ecosystem and the food web.
Not only is the beetle epidemic killing off the ecosystem for the Grizzly Bears, it is also contributing to this little problem we keep hearing about on the news, and by Politian’s, Global Warming. We hear about it all the time, witness its effects every season, but some people still don’t believe it. The way that the Pine Beetle is affecting Global Warming is that it is changing the lush green pine forest into brown dead zones that are releasing carbon into the atmosphere. The Pine Beetle outbreak is actually threatening the balance of carbon in the region (Ira Platow 1). Carbon is a greenhouse gas, this means it has heat trapping features so it retains heat from the sun and gradually heats up the
Since then, tons of soot have been deposited on the country side around industrial areas. The soot discolored and generally darkened the surfaces of trees and rocks. By 1819, the proportion of dark moths in the population had increased significantly. Researchers found that the light-colored lichens covering the trees were being killed by sulfur dioxide emissions from the new coal burning mills and factories built during the industrial revolution. Without the light colored background of the trees to protect them from the predatory birds, the light colored moths were more visible and lost their selective advantage to the dark colored moths.
Colony Collapse Disorder The colony collapse disorder of honeybees has become a very problematic issue. The Natural Resources Defense Council states that nearly that nearly one-third of all honeybee colonies in the country have vanished, putting many fruits and vegetables at risk. A controversial type of pesticide called neonicotinoids has become a prime suspect in this phenomenon, as it affects bees’ sense of direction and making it hard for them to find home. In order to prevent this disaster from continuously occurring, neonicotinoids should be banned or used more sparingly and replaced with an alternative type of pesticide. Author Brandon Keim, author of article “Controversial Pesticide Linked to Bee Collapse” states neonicotinoids began to be used in the mid-1990s as less-toxic alternatives to human-damaging pesticides.
Indiana Bat The Indiana Bat has been on the endangered species list for New Jersey for over 40 years. This bat species lives in various states of the Eastern US. They are small bats that hibernate in caves and abandoned mines in large numbers. According to US Fish and Wildlife Service, a fungal disease called White Nose Syndrome is one reason that these bats are on the New Jersey endangered species list. When they are not hibernating, they make shelter among trees and their habitat is destroyed when forests are cleared thus leading to their
