5 Most Common Maple Varieties in North America

Acer  sp. is the  genus of trees or shrubs commonly known as the maples. Maples are classified in a family of their own, the Aceraceae, and  there are approximately 125 species worldwide. The word Acer is derived from a Latin word meaning sharp, and the name refers to the characteristic points on the leaf lobes. The maple tree is the national arboreal emblem of Canada.   There are actually twelve native maples found in North America, but only five are commonly seen across most of the continent. The other seven that occur regionally are black maple, mountain maple, striped maple, bigleaf maple, chalk maple, canyon maple, Rocky Mountain  maple, vine maple, and Florida maple. Your chances of seeing a native maple are good in both the urban landscape and in the forest. With few exceptions (Norway and Japanese maples are exotics) you will find these native maples and their cultivars in profusion. Common North American Maple Species Sugar maple  or Acer saccharum.  The star of eastern North American fall foliage viewing and principle source of maple syrup. It normally grows 80 to 110 feet in height, but 150-foot specimens have been known. Compared to other maples, sugar maples color unevenly in the fall; sometimes yellows, oranges, and reds are all seen at the same time.  Red maple  or Acer rubrum. The most widespread maple in eastern North America and ubiquitous  in both the urban and forest landscape. It normally grows to a mature height of about 50 feet. It is a very popular landscape tree but is considered invasive in some forests, where it crowds out native oaks. The upper side of the leaves is green, with the lower side silverish in color. In older trees, the bark is very dark. Fall color is usually a deep red, though some trees may exhibit orange or yellow.  Silver maple  or Acer  saccharinum.  A fast-growing maple used largely as a shade tree, but with problems. This maple is brittle an d subject to breakage. The roots shallow and can cause property damage. At maturity, it may be 80 feet tall. The underside of the leaves is a soft silver in color; fall color is usually a pale yellow.  Boxelder  or Acer negundo  - The most common maple sp. in mid-western North America, and the only maple with pinnately compound leaves. Boxelder has the largest range of all North American maples. It is a fast-growing but short-lived maple, and in favorable conditions, it may grow as much as 80 feet in height. Leaves turn yellow in the fall.  Bigleaf  or Acer macrophyllum.  Restricted to the Pacific Coast, this tree is the most massive of North American maples. It can grow to be 150 feet tall or more, but more typically tops out at 50 to 65 feet in height. In fall, the leaves turn golden yellow.   General Identification Tips The deciduous leaves on all maples are arranged on stems  opposite  each other. The leaves are simple and palmate shaped on most species, with three or five main veins radiating from the leafstalk. The leafstalks are long and often as long a the leaf itself. The boxelder alone has compound leaves, with multiple leaves radiating from the leafstalk.   Maples have small flowers that are not very showy and form in droopy clusters. The fruit is winged key seeds (called  double  samaras) and develops early in the spring. Very visible are the redbuds and new red stems on red maple. Maples have bark that is generally gray but variable in form. Good identifiers of maples in dormancy are: Crescent-shaped leaf scars with three bundle scarsA terminal bud that is egg-shaped and slightly larger than the lateral buds on the branchStipule scars are absent  Opposite leaf and twigs

Essay on Security Issues of Ambient Networks - 2196 Words

In this essay we will present security issues of a networking concept referred to as ambient networks, which aims to enable the cooperation of heterogeneous networks belonging to different operator or technology domains. In this way, it appears as homogeneous to the users of the network services. Providing security in ambient networks is a huge challenge. The main reason is that the traditional security model is not valid anymore. Traditional security assumes that there is a vulnerable channel between communicating parties, where eavesdropping, modification of messages or denial of service attacks can occur. But it also assumes that the sender and receiver operate in some form of secure environment. Hence all models of attacks focus on†¦show more content†¦Besides it should be almost invisible and moreover it should be nowhere unless we need it. Figure 1 shows an overview of the Ambient Information Network. The flow of information through this network is controlled by proprietary server software built using best-of-breed network software technologies and is currently deployed on a server farm in Cambridge, Massachusetts. Ambient has partnerships with many content providers who generate high-volume content feeds describing a wide variety of types of information, including weather observations, weather predictions, auto traffic patterns, stock market performance, electricity market performance, astronomical data, personal bank account data, ski resort reports, and many others. Our central server records millions of individual pieces of content each day and greatly compresses and aggregates it so that it can be efficiently and economically transmitted over the long-range Flexâ„ ¢ paging network.

The Driving Age Should Be Raised to 18 Free Essays

The Driving age should be raised to 18 Since people have changed, some driving laws ought to change as well. The Department of Motor Vehicles must Observe and Acclimate unto the Motor Vehicle’s Operators with Revisions. While observing, DMV will find that many drivers treat their vehicles like mini living rooms and have mocked the customs and values of driving and they ought not to tempt children to do the same. We will write a custom essay sample on The Driving Age Should Be Raised to 18 or any similar topic only for you Order Now Many drivers observe people driving while eating, text messaging and watching videos. â€Å"10 percent of drivers aged 14 to 24 years old are on their phone at any time. (NHTSA, Insurance Institute for Highway Safety) To adapt unto this grave temptation of drivers is to mandate the legal age to 18 years old. I have been driving for 33 years and I was 16 years old when I was given a legal permit to drive a motor vehicle. Nevertheless, in 1979 the phones were in the living rooms, kitchen walls and the bedrooms of our houses. We as â€Å"Baby Boomers† did extremely well, while driving with the customs and values of being â€Å"An Motor Operator. † There weren’t many distractions of our own. It was a practice of being attentive with other motorists which made it immeasurably easier to drive safer. It was also and always a predictable effect as well when we smiled at the other motorists. We had conceived a good sense of motivation and inspiration, not road rage. I can recall the time when I was driving and had an a pair of encounters with the parents of two of my friends while crossing each other at an intersection upon separate occasions when in both instances, the parents conceived inspiration from my attentiveness, smile and a kindly wave. Months later, I was a passenger in both of my friend’s new car. With this calling to mind, underage drivers were adequately allowed to drive, because people were adequate drivers. People were not treating their cars like mini living rooms. DMV should take the stand upon this issue, because many parents feel proud and dedicated to allowing their children to drive. Many will allow them because they themselves starting driving at the tender age of 16. Consequently, with today’s unprincipled driving practices of unsafe drivers, DMV should adhere unto the fact that â€Å"The number one source of driver inattention is use of a wireless device. † (Virginia Tech/NHTSA) Just a week ago, I took interest to observe closely my associated-by-default-drivers coming home from work in the rush hours of the day and noticed 6 out of 10 motorists were unsafely driving while eating, texting or video watching. Who would want their child to drive like them or drive besides them? Only proud parents I presume. Another case in point, is that under-aged drivers do drive with heavy duty vehicles, such as Tractor-trailers weighing over 80,000 + pounds and from my encounters from 2007 through 2008, when I was driving a heavy loaded cab-over tractor double trailer tomato truck. I was generally in the right lane most of the time and had numerous encounters with young drivers entering the on-ramp driving like Mickey and Minnie Mouse scurrying casually upon the ramp. On one occasion, a young teen was text messaging or perhaps dialing a number. Another occasion, I remember a car load of teens were excitingly viewing a video of interest. And another occasion, I’d encountered a young boy reclining in his car seat like he was in a concert listening unto his stereo. On all occasions, I had to rapidly down shift gears and with gear in neutral, I revved up the accelerator in order to create a loud sound effect to get their attention. Every time, they either dropped their cell phone, stopped watching their video or sat up straight from their reclining seat and accelerated like they should’ve done with a 55 mph heavy truck. Each of those times, I exhaled a great sign of relief. Not because of my wrong doing, I was rightfully in my lane, but because I will have to take out my fire extinguisher and assist with their calamity. A child’s at that. My heart is heavy with concern from this recollection. Some driving laws ought to change. A lot of drivers have changed dramatically over the years. There are drastically too many unethical driving practices for the young and innocent to be exposed to. Therefore, the driving age should be raised to 18. Children ought to be exposed unto the wonders and the beauty of the world, not to be imperiled by the vulnerabilities of them, by driving in this age and time. I shall not speak a thousand words to convey that a lot of drivers have changed for the worst and a revised law will surely help change the minds of proud and dedicated parents by raising the age limit to 18 years of age to operate a motor vehicle.
