The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups. This shows that an environment can work to stabilize itself without human interruptions. Plants can ensure they don’t overpopulate an area by self-thinning and species can survive with predators using the environment they were given. Introduction Competition for resources is seen in all species and environments around the world. Since the Earth’s natural resources are limited, it necessary for species of all kingdoms to fight in order to gain enough nutrients in order to not only live but thrive and go on to produce future generations.
Mann Gulch Fire On August 5th, 1949 what was thought to be a routine day in the lives of 16 smokejumpers, will be remembered within the U.S. Forest service as well as firefighting history. The Mann Gulch fire occurred in Montana’s Helena National Forest, and prior to this incident, no smokejumper had ever died fighting a wildland fire. The fire, which was caused by lightning strike, was originally spotted at 12:25 pm. Due to the remote location and lack of roads; smokejumpers were dispatched to the incident. Forman Wagner (Wag) Dodge and his crew made their jump a few hours after the call.
Eruption of Mount St. Helens 1980 On May 18, 1980, Mount St. Helens erupted and killed fifty-seven people. This was the most recent earthquake in the main forty-eight states since 1915. Mount St. Helens is a stratovolcano located in the state of Washington. A stratovolcano is made up of hardened pumice and lava. Before 1980, the last eruption of Mount St. Helens was between 1840 and 1850.
Using systematic sampling to identify and measure the nettle leaves, a strong correlation between light intensity and nettle leaf length was found where nettles that were exposed to lower amounts of sunlight had greater lengths. 1. Research and Rationale Being a very common plant, nettles tend to grow all around the planet and are vital for our ecosystem. Furthermore, nettles are also beneficial to us as they can offer countless medical aids for instance, they can encourage bleeding to cease after dental surgery, they can help with infection and inflammation within the urinary tract and stop hair loss. Aside from the medical uses, nettles can be used to make hot beverages such as tea and delicious nettle soup .
The late William T. Pecora, a former Director of the USGS, was quoted in a May 10, 1968, newspaper article in the Christian Science Monitor as being "especially worried about snow-covered Mt. St. Helens." On the basis of its youth and its high frequency of eruptions over the past 4,000 years, Crandell, Mullineaux, and their colleague Meyer Rubin published in February 1975 that Mount St. Helens was the one volcano in the conterminous United States most likely to reawaken and to erupt "perhaps before the end of this century." This prophetic
The rings of growth in the lawn are caused by the release of nutrients, specifically nitrogen because of the activity of the fungus living on organic matter in the soil. These organisms are mushroom or “puffball” forming fungi. Some mushrooms or puffballs are very poisonous when eaten and it is important that they are routinely destroyed if small children are likely to be attracted to them. There are three kinds of fairy rings. The first type has no mushrooms just stimulated grass growth revealing the activity of these fungi in soil.
Environmentally, a positive impact is “as generalist feeders, they can have more than one food source and other insects are their prey (University of Arkansas division of agriculture, 2006). In the South Eastern United States, fire ants eat the natural predator of the sugar cane and cotton (Roberts, 2011). When fleas and ticks are involved, fire ants eat the larval and pupal stage fleas and ticks and reduce the chances of Lyme disease and other nasty diseases (Roberts, 2011). The negative impacts of fire ants on the environment are the disfiguring of landscapes, and the stinging of people, pets and livestock (Steven Tvedten. The Best Control (2nd Edition).
This is an analysis on what is known to be the largest earthquake and biggest tsunami ever to hit Japan on March 11, 2011. The earthquake and tsunami Japans coast lies in ruins after the earthquake hit followed by the tsunami picking up everything in its path like cars, houses, and warehouses. Seismometers, strain gages, and title gages records the disaster. P-waves travel at four miles a second and within seconds warnings flash across the country. The S-waves shake the ground making earthquakes so damaging and the reactor core is shut down (Kerger, 2011.
Practical application of this knowledge will lead to healthier plants and improved plant growth with greater uniformity. It also helps to minimize biosecurity risks. Several serious soil borne plant pathogens are being spread around the world with nursery plants. Many tropical soils harbor numerous soil borne pathogens for several years which often limit crop production. These pathogens includes various fungal, bacterial and some
They help our planet by pest control (eating massive amounts of insects), monitoring our environment by pollinating the flowers of various plants, keeping our environment balanced, as well as recycling nutrients into our earth; without birds, humans are more likely to cease existing. Besides the biological reason as to why birds are important there are also more reasons such as art. Birds are beautifully and uniquely made making them pleasant to observe, photograph,
