rate and will come up with newer and more innovative ways of improving the way they process things. In computer systems‚ the technologies that evolve every time will always be both software and hardware components of a computer. So it is also very wise to upgrade the operating system since this is the system that interfaces hardware‚ software‚ and human interaction. Because operating systems are one of the core technologies that manage software and hardware systems‚ it must always be upgraded constantly

What is biodiversity and what are the impacts do invasive species have on biodiversity? Biodiversity is the variety of animal and plant life in a particular habitat; it also means all of the different natural processes on the earth. There is estimated to be more than 11000 tree species in the amazon rainforest‚ that a huge amount of different species and that’s only for one part of the world. It is important to have biodiversity‚ Biodiversity boost ecosystems productivity. What is productivity?

4/10/11 James Ross Aftermath of the Invasion The introduction of invasive species into new environments is a problem that plagues the entire planet. Humans have been moving species around the world and introducing them into new environment for millennia. Many introduced species become invasive‚ disrupting ecosystems and threatening the survival of other species‚ sometimes driving them to extinction. Some invasive species‚ including some insects‚ seem to thrive particularly well in already degraded

Loss of Species Every year a new species gets placed on the endangered species list‚ extinction is a natural process but due to human activity there has been a rapid decline in the wild species population. Loss of habitat or alteration‚ hunting‚ introduction of foreign species‚ and disease are major culprits in the extinction rate. The protection of species is an important element to the survival of biodiversity as well as human sustainability. The loss of a species means humans will lose out

A keystone species is defined as one that has a critical role in determining and maintaining the overall relationship of plants and animals within an ecosystem. If a keystone species is removed or declines‚ the nature of the ecosystem will change dramatically. Sea Otters — A Classic Keystone Species The classic tale of a keystone species is that of the sea otter‚ which was once found in abundance along the West Coast of North America. The story goes something like this: 1. European and

Ring Species: A Catalyst for Speciation After spending time on the Galapagos Islands studying the origin of various species‚ former divinest Charles R. Darwin proposed the evolutionary theory of natural selection‚ a mechanism by which advantageous variations in a population are preserved while unfavorable variations are lost (Berkeley‚ 2008). As a result of these variations‚ some individuals are better acclimated to their environment than others. This results in the better-suited individuals outcompeting

Biodiversity has been on the decline over the past century and the background rate has been mostly accelerated by the humans. Considerable damage has already been done. Possible solutions have been discussed and categorising species according to how in danger they are is one of those solutions. Below are some of the threatened organisms in different continents around the world. TABLE OF CONTENTS Africa Mammals Birds Reptiles Amphibians Fishes Asia Mammals Birds Reptiles

Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new ecosystems is caused by a number of reasons. In

Endangered Species Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals‚ birds‚ reptiles‚ amphibians‚ and (many people do not consider them) plants .CAUSES OF EXTINCTION Millions of years before humans‚ extinction of living things was linked to geological and climate‚ the
