  • Middle Shore Several Species
    4,791 words
    The seashore is a habitat that contains a wide range of micro habitats and ecological niches for different creatures. This is mainly due to the effects of the tides, that rise and fall twice each day. Tides are the vertical movement of water in a periodical oscillation of the sea, due to the gravitational pull of the sun and moon. The tides are on a semi-diurnal cycle, so there are two high tides and two low tides each day. Due to the orbit of the moon, the tides also have a monthly cycle. This ...
  • Best Adapted Species For Their Environment
    1,440 words
    In The Origin of Species, Charles Darwin poetically entailed, "There is grandeur in this view of life... ". Personifying Nature as the ultimate breeder, Darwin infers and hypothesizes what is arguably the most fundamental and profound scientific manifesto that governs what we now know about modern science and the science of discovering our past. His two theories of Natural Selection and Sexual Selection effectively bridge the gap that his predecessors could not. These concepts are imperative as ...

People feel that extinction is very sad, and try to protect life-forms on the brink of extinction by naming them 'endangered species' and being nice to them. Each living organism whi...
  • Biological Species Concept
    1,406 words
    Biological Species Concept (BSC) What are biological species? At first glance, this seems like an easy question to answer. Homo sapiens is a species, and so is Canis familiaris (dog). Many species can be easily distinguished. When we turn to the technical literature on species, the nature of species becomes much less clear. Biologists offer a dozen definitions of the term 'species'. These definitions are not fringe accounts of species but prominent definitions in the current biological literatur...

  • Human Man's Amino Acid Sequences
    2,992 words
    Evolution From A Molecular Perspective Introduction: Why globular evolution? Evolution has been a heavily debated issue since Charles Darwin first documented the theory in 1859. However, until just recently, adaptation at a molecular level has been overlooked except by the scientific world. Now with the help of modern technology, the protein sequences of nearly every known living thing have either been established or are in the process of establishment, and are widely accessible via the internet...
  • Species
    319 words
    Habitual instincts are inherited within each species. Ants and bees build their nests and hives with no previous experience. Birds migrate and build homes according to their unique inner senses. But instincts too may change over time as "consequences of one general law leading to the advancement of all organic beings... multiply, vary, let the strongest live and the weakest die". Other chapters deal with related topics: hybridism; living species compared to those of ancient geological periods; e...

Symbiosis- Permanent close association between 2 or more organisms of different species. My friend's new dog made friends with his current dog, ...
  • Common Name Of Blue Green Algae
    1,053 words
    Cyanobacteria is any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one time treated as algae, hence the common name of blue-green algae. Algae have since been reclassified as protists, and the prokaryotic nature of the blue-green algae has caused them to be classified with bacteria in the prokaryotic kingdom Monera. Like all ...
  • One Variety Within A Species
    569 words
    Differences within a species are indistinguishable at first, but gradually may develop into variety that can restrict one group', range or ability to get food or escape predators... Thus, "varieties tend to become converted into new and distinct species... and throughout nature the forms of life which are now dominant tend to become still more dominant by leaving any modified and dominant descendants". Chapter : Struggle for Existence. ".. When a plant or animal is placed in a new country amongs...
  • Samples Of Organisms From Deep Sea Communities
    551 words
    Snelgrave and Grass le in The Deep Sea: Desert and Rainforest published in Oceanus, volume 38 in 1995 argue that the popular belief that the deep sea is little more than an ocean desert is a pure fallacy. Contrary to such thinking a multitude of benthic organisms dwell on the ocean bottom; despite the frigid temperatures and high pressure, a large heterogeneity of creatures, rivaling in variety and number those inhabiting tropical rainforests, thrive in this environment. The analogy of the ocean...
  • Natural Existence And Balance Of The System
    469 words
    In the early 18th century, bluebells were bluebells, it didn't matter where they came from, when they bloomed or what their leaves looked like - if the flowers were blue, that was pretty much good enough. By the same token, mushrooms were mushrooms, some were palatable, some were offensive and some would induce death, but they were all mushrooms. Swedish botanist Carl von Linn, better known as Linnaeus, recognized how the casual terminology of his time couldn't accurately name the species of Eur...
  • Community Ecology And Ecosystem Ecology
    2,419 words
    Ecology is the scientific study of the interrelationships of plants, animals, and the environment. In recent years, the word has sometimes been misused as a synonym for environment. The principles of ecology are useful in many aspects of the related fields of conservation, wildlife management, forestry, agriculture, and pollution control. The word ecology (Greek, oikos, "house", and logos, "study of") is generally believed to have been coined by Ernst HAECKEL, who used and defined it in 1869. Th...

    The Ethical Basis for Ecosystem Management Andrew J. Green Ecosystem Management: The Human Dimension Establishing an environmental ethic is of utmost concern to the human species to better comprehend our place in the world and our potentials for the future. In doing so, we must extend our thinking of rights and responsibilities. I believe we must incorporate not only a temporal component, but also a spatial understanding of the world as an organic biotic community and how consumption is a part o...
