Habitat size determines diversity relationship(Edition of Nature‚ March 28 2002). In the research of specie diversity ‚ it was found out that more productivity was done when two different types of species were in one area. It was also said that diversity goes down but as it goes down the productivity of the species increase. Variables:

Extinct Species: Dodo Bird Joseph Sulaiman Pd.2 The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves‚ it stood about a meter (3.3 feet) tall‚ weighing about 20 kilograms (44 lb)‚ living on fruit‚ and nesting on the ground. The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history and was directly attributable

One cutting-edge present technology that this paper will explore is the da Vinci Surgical Robotic System [1]‚ which is being used at Johns Hopkins [2]. This system performs minimally invasive cardiac surgery; it makes the cuts more precise and saves lives. In the future‚ robotic surgery will become more advanced‚ as sensory feedback in the da Vinci system could be a future breakthrough that could revolutionize the whole concept of robotic

According to the study of Bughio‚ Mangrio‚ Abro‚ Jahangir and Bux‚ it has been found that Eucalyptus species release volatile compounds such as benzoic‚ cinnamic and phenolic acids which inhibit growth of crops and weeds growing near it. Phenolic acids and volatile oils released from the leaves‚ bark‚ and roots of certain Eucalyptus spp. have deleterious effects on other plant species.

the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense‚ it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods‚ such as the Monoplacophora‚ which superficially resemble small limpets‚ may also informally be referred to as "snails". Snail-like animals

Sexual dimorphism describes the often observed phenotypic or behavioral differences between males and females of the same species. Darwin addressed these differences in his first book “On the Origin of Species” and described them as resulting from “sexual selection”. Sexual selection is both different from natural selection and a mechanism of natural selection. Like natural selection‚ variation in individuals is the driving force behind the differences in their survival and reproductive success

Sex change in Aquatic Species By: Gobezai Abebe Introduction. Many species of invertebrates‚ fish and plants undergo a process which is rare and requires detailed research to understand (Allsop and West‚ 2003). The process that they undergo is known as sex change. Focusing specifically on hermaphroditic fish‚ sex change can occur in two directions. One direction that sex change can occur is the change from female to male which is known as protogyny (Allsop and West‚ 2003; Kuwamura et.al‚ 2002;

The article “Rapid Evolution Changes Species in Real Time”‚ written by Jane Braxton Little‚ is a controversial look at evolution. This article presents a clear thesis‚ Little‚ along with scientist David Reznick‚ both believe that the process of evolution can be sped up. The process of evolution is due to environmental conflicts or possibly created by man. Throughout the article Little consistently focuses on her main thesis‚ and provides multiple examples to help back up her claims. Reznick states

Many species of bees have recently been put on the endangered species list. They are vital to our food supply and help our crops grow. They help produce food‚ fiber‚ and shelter for us. Waves from cell phone towers or the rising heat could be the reason for the species decline in number. We can help to protects the bees by raising hives on our own‚ and by trying not to use harsh pesticides. Bees are what pollinate our crops. Without them the flowers could not be pollinated and would die. Without
