The Ash Borer exclusively attacks Ash trees. When an ash borer infests a tree it doesn’t do any immediate outer damage. What actually occurs is the adult female lays her eggs under the bark of the tree. As the eggs mature and grow they morph into larva. When the EAB is in its larva form, it is also the most damaging.
The article, A Reporter At Large: We Have No Bananas talks about Tropical Race Four, a soil-borne fungus threatening Cavendish banana cultivation. The plants have been wiped out in Asia and Australia, and Latin America may be next. There is a variety called Cavendish, which is a nineteenth-century British explorer in a household garden found it in southern China. It Represents 99% of the banana export market, as there are more than a thousand kinds of banana in the worldwide. A very large majority of banana varieties are not really able to grow for international trade, according to the article, their skin is too thin, or their pulp is very bland.
What might have happened if the lightning had struck a healthy oak instead? After two months of little rain, and days and days of temperatures in the 90's, the meadow grasses were dry and cracked. The coming rain would have alleviated the dryness and made the valley less susceptible to a fire. Moisture and wind can determine whether a forest fire will break out or will not break out. A bolt of lightning struck a pitch pine which 2 was on the valley's upwind edge.
This strong species is a voracious predator of insects and other small prey. Cane toads possess the capability of poisoning their predators. The introduction of this species to Australia was directed as a form of biological control. Cane toads were supposedly a ‘solution’ to the pest beetles in the sugar cane industry in 1935, before the use of agricultural chemicals became widespread. Although this ‘solution’ failed in its attempts to control the issue, cane toads were very successful at invading the ecosystems of Australia’s north.
They say that there are even some undiscovered species hiding in there, maybe one could help us cure cancer. According to Treehugger, “The Amazon Rainforest, one of the largest and most diverse ecosystem on the planet, has been a virtual treasure-trove for ambitious biologists aiming to uncover new species,” (Stephen Messenger, Amazon Rainforest teeming with Life). The Amazon consists of different layers because of the amount of sunlight and water each plant needs. Large trees create a layer of leaves blocking most of the sunlight from filtering in. There is a variety of underbrush and plants that require water but not a lot of sun.
The close proximity to land is a major threat to the harp seals, because they are closer to both natural predators and human commercial hunters. In efforts to protect the seals the Canadian Government has reconsidered laws currently placed on commercial hunting. Gabel’s article suggests the complete shutdown of commercial hunting. This change would have a major impact on the lively hood of commercial hunters. In order to counter balance the extinction of the harp seal pelt
These trees and other forests are disappearing. (Doc A, map). The following are ways I want this money to stop deforestation in America so it can become as environmentally conscious as possible: set borders up for loggers, protect old trees by making them landmarks, turn a forest into a National park, and put a tax on logging. Trees must be
Moreover, the Amur Leopard has longer legs than normal leopards, these long legs helps the leopard walk in and through snow easily. One of the environmental conditions that is affecting the Amur Leopard, is lighting the forests to turn into grassland for farming. By lighting up the forests the people are destroying the habitat of this species. Furthermore, by building natural gas pipelines, roads, and railway networks, humans are not allowing Amur Leopards live in their territory, and also not letting them have more space to roam. Logging can also contribute to these problems.
China happens to contain a total of 60% of the habitats compared to those areas. Snow Leopards prefer broken terrain of cliffs, rocky outcrops and ravines. These types of habitats provide good cover and a clear view to find prey. Invasive Species It’s not competing with any other invasive species at this point in time because these animals can eat animals up to two times their own size. However the Snow Leopard does compete with hunters who illegally hunt them for the selling’s of their organs.
The forests “breathe” by removing large amounts of carbon dioxide from the air and giving off oxygen. It is feared that the loss of rain forests will increase CO2 levels in the atmosphere and result in global warming. Tribes Tribes Why are indigenous people in danger? When the first European explorers arrived in Latin America, they brought with them diseases such as small-pox, measles, and even the common cold. Europeans were used to these illnesses so they didn’t get sick, but indigenous peoples had never been exposed to these diseases before so many of them became sick and died They live what is called a sustainable existence, meaning they use the land without doing harm to the plants and animals that also call the rainforest their home.
