Coniferous Forest


The Coniferous Forest is a generally frigid forest area with a myriad of animal species and an abundance of plant life ranging from mushrooms to its ever useful evergreen trees. These evergreen trees along with other pine shaped trees are long and narrow, covering many mountains as well. Evergreens being so prominent in the area do certainly hold importance to men today. From usage regarding Christmas holiday to using coniferous oil produce as cleaning supplies. The Coniferous Forest and its trees are certainly a benefit to society and should definitely be preserved.

James lovelock Summary



My presentation was on James lovelock and he was born on July 26, 1919 in Letchworth Garden City in the United Kingdom. He graduated as a chemist from Manchester University in 1941 and in 1948 received a Ph.D. degree in medicine from the London School of Hygiene and Tropical Medicine. In 1959 he received the D.Sc. degree in biophysics from London University. He is the author of approximately 200 scientific papers, distributed almost equally among topics in Medicine, Biology, and Instrument Science. He has filed more than 50 patents, mostly for detectors for use in chemical analysis. The electron capture detector was important in the development of environmental awareness. It revealed for the first time the global distribution of pesticide residues and other halogen bearing chemicals. This information that enabled Rachel Carson to write her book, Silent Spring often said to have initiated the awareness of environmental disturbance. Mostly what he is known for is the Gaia hypothesis The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. The hypothesis, which is named after the Greek goddess Gaia, was form by James Lovelock.

Chernobyl Disaster

My presentation was about a disaster that took place in Ukraine. It was the largest uncontrolled radioactive released into the environment, that was ever recorded for any civilian operation. The disaster was a unique event and the only accident in the history of commercial nuclear power, where radiation-related fatalities occurred. It was caused while the testing of the reactor number four. They were testing the reactor, to determine how long turbines would spin and supply power to the main circulating pumps, which in that moment a loss of the main electrical power supply occurred. The reactor was on an unstable condition when the people tried to shut it down, and the explosion happened. It caused an explosion and a melt down.That caused reactor number four to spew over 200 times the amount of radiation. The Chernobyl Disaster affected over seven million people, including the areas of Belarus, Russia, and Ukraine. The incident caused people to evacuate the location, and some never came back home. After the disaster, it caused people to become disabled, dead, or some even committed suicide. There were health issues such as the rise in thyroid cancer or any thyroid disease, immune system disorders, lung,heart, and blood problems, and finally learning problems for children. To solve that event, $400 million, U.S dollars, was put into that event, to improve the situation. 600,000- 800,000 firefighters and emergency workers were sent to help out from the Soviet Union to put out fires, bury radioactive equipment, shut down all Chernobyl reactors, and they also created a tomb to surround the radioactive material that collapsed from the reactor.

CLIMATE:

Hot semi-arid climates tend to be located in the tropics and subtropics. These climates tend to have hot, sometimes extremely hot, summers and mild to warm winters. Snow rarely (if ever) falls in these regions. Hot semi-arid climates are most commonly found around the fringes of subtropical deserts.



Cold semi-arid climate tend to be located in temperate zones. They are typically found in continental interiors some distance from large bodies of water. Cold semi-arid climates usually feature hot and dry (often exceptionally hot) summers, though their summers are typically not quite as hot as those of hot semi-arid climates.



physical characteristics:

Landforms in semiarid deserts are often carved by sudden torrential rains and flash flooding.

bodies of water:

water resources in arid and semi arid are very scarce due to the low rainfall and high evaporation.  



environmental importance:

Arid environments are limited and variable rainfall that supplies resources in pulses. Resource pulsing is a special form of environmental variation, and the general theory of coexistence in variable environments suggests specific mechanisms by which rainfall variability. might contribute to the maintenance of high species diversity in arid ecosystems.spiked lizard

What do you think about deer culls?

December 3, 2012 (Newark, NJ) – District 5 Freeholder Brendan W. Gill of Montclair, Chairman of the Freeholder Board’s Deer Population Control Committee, convened a meeting of his committee on Thursday, November 29, 2012, at the Hall of Records.  
 
Director Salvante gave an overview of pertinent statistics, including the fact that a total of 2,654 deer have been removed from county property since 2008 (818 culled, 545 unborn fetuses, 1,291 killed in vehicle accidents on county roads). He also pointed out that the success of the County’s deer management program (whether due to culling or to the effectiveness of roadside reflectors) was manifested in the reduction in the number of deer killed on county roads: 182 (2012), 233 (2011), 229 (2010), 283 (2009), 363 (2008) and 303 (2007).
 
Bernier discussed the various elements of the deer management program and emphasized that the hunting aspect “…is not in any way intended to provide recreational sport.” He added, “The hunt is intended strictly for the purpose of deer management, and has three goals: to preserve bio-diversity in the county’s woodland and fields (especially its parks) by allowing for forest re-generation to reverse the damage done by the over-browsing of deer; to provide aesthetic and financial relief to homeowners whose landscaping has been damaged by deer; and to reduce the threat to public safety caused by deer-related motor vehicle accidents.” He also discussed the extensive efforts to notify the public of hunts, the stringent rules in-force to make the hunt as safe as possible, as well as the effort to use skilled and experienced marksmen and to include as many Essex County resident marksmen as possible.
 
Bernier also responded to questions from Freeholder Gill, other freeholders and members of the public about alternative population control means besides hunting. Regarding “trap-and-transfer”, he pointed out that it was attempted years ago in Essex County and failed; that is very difficult to accomplish, logistically; and that it often results in the death of deer from trauma and injury anyway. He also discussed the current impediments to the use of fertility control/immunocontraceptive drugs such as PZP and GonaCon: legality – the State requires that deer first must be captured, the drug must be administered by veterinarians, and permission must be granted in writing from all property owners within 2,000 feet of the designated darting area if the deer are to tranquilized prior to inoculation; cost - recent analyses indicate the cost to be $1,000 per deer, and likely higher here in Essex County, due mostly to the mandated participation of veterinarians; and application, the most problematic of all - 90% of the female deer must be immunized, they must be captured, tagged and kept track of to know when they must be re-treated, and they must be treated at least every year, if not every year. He went on to add that even if all of these impediments were to be worked out, the use of these drugs will only “…allow you tomaintain a population at or close to what it currently is; what it will not do is reduce the population.” “So, if you have too many deer already, fertility control agents are not going to bring that population down for at least ten years.”
 
Freeholder Gill emphasized the importance of moving forward with forest regeneration efforts and asked, “When are we going to reach the point where the number of deer is low enough that we won’t need to hunt anymore?” Bernier answered by saying that forest ecologists generally say a population of 20 deer per square mile will permit a healthy forest to survive, “…but, your forests are far from healthy and current research suggests you probably need to get the density down to about 5 per square mile in order for forest regeneration to really have the opportunity to succeed.” At the current rate, he indicated that the hunt in South Mountain Reservation would probably have to continue for another 2 or 3 years, that it would take longer at the Hilltop Reservation, and that at Eagle Rock, perhaps a hunt every other year for a while would suffice.

                                                  Tropical Savanna
                           By, Colin Nestor

Info: The biome from the project was well constructed and expresses the Tropical Savanna characteristics flora, fuana, climate, etc.

Climate: Tropical wet and dry climates. The Tropical Grasslands is hot year around typically never dropping under 64 degrees Fahrenheit. rainfall annually if from 20-50 inches per year.

Physical Characteristics: The characteristics of a savanna are a grassland mostly dominated by grass and other plants such as shrubs and tree-sized woody plants.The tropical Savanna supports a great seasonal environment for large mammals and other populations of animals.

Flora/ Fauna:      
     Animals:

 Plants:

Tropical grasslands is dominated by grass, about 3 to 6 feet tall. The plants develop in regions where the climax community should be forest. Drought and fires although prevent the development of many trees.

Environmental Importance: Tropical grasslands are characterized by  very deep, rich soils and they are very important for the absorption, retention and purification of water.
