  • A census is a survey taken to gather information about a certain group – marine life!
  • Transcript

    • 1. Introduction to Ecology: ‘Decade of Discovery’<br />Article from BBC.co.ukworld news website <br />From: Oct. 4, 2010<br />In Cambodia, a new species of rhacophorid frog, Chiromantissamkosensis, was identified in 2007. It is distinguished from other species of Asian Chiromantis by having green blood and turquoise bonesRead more: http://www.cbsnews.com/2300-500142_162-4668710-5.html?tag=page#ixzz11fxWUi2w<br />A new plant species, AeschynanthusMendumiae, discovered on the southeastern slopes of Laos&apos; Phuo Yang Mountain, is one of 1,068 new species identified in the Greater Mekong from 1997 to 2007 in the WWF report, &quot;First Contact in the Greater Mekong.&quot;Read more: http://www.cbsnews.com/2300-500142_162-4668710.html#ixzz11fwtSLWh<br />The Dragon millipede Desmoxytespurpurosea, from Lansak district Uthaithani Province, Thailand. This formidable-looking creature sees off predators first with its spiny bright-pink skin and second with glands that produce cyanide.Read more: http://www.cbsnews.com/2300-500142_162-4668710-2.html?tag=page#ixzz11fxEQ8Cf<br />
    • 2. Ecology is the study of the relationships between the natural world and all the living and non-living things in that environment<br />
    • 3. Article Information<br />This article tells us about a research study completed on the FIRST census of marine life<br />Involved almost 3000 researchers from 80 different countries, and over 9000 days at sea!<br />Key questions:<br />What LIVED in the oceans?<br />What DOES live in the oceans?<br />What WILL live in the oceans?<br />
    • 4. Discovered many species thought to be rare<br />Collected many specimens and are identifying almost 6000 new species!<br />Oceans are changing quickly, so it is important to know what lives there<br />Questions to consider:<br />Do you think this is an important study? Why/why not? Explain.<br />Now that we have more knowledge about the oceans and the life found in oceans, what should we do with this information?<br />This member of the new Kiwaidae family of crabs, discovered near Easter Island, was named Kiwahirsuta because of its furry appearance. From:http://news.bbc.co.uk/2/hi/science/nature/8523389.stm<br />This new sponge produces a chemical with anti-cancer propertiesFrom: http://news.bbc.co.uk/2/hi/science/nature/8523389.stm<br />
    • 5. Levels of organization in Ecology<br />Biosphere<br />Ecosystem<br />Community<br />Population<br />Individual (species)<br />
    • 6. SPECIES<br />Examples: Species of frog: water frog, red-eyed tree frog<br /><ul><li>Species of horse: Clydesdale horses, Andalusian horses</li></ul>Similar organisms that can successfully reproduce among themselves in their natural environment<br />THIS MEANS: they produce offspring that can reproduce as well<br />
    • 7. POPULATION<br />A population is made of many of the SAME KIND of species that live in the same area<br />Compete with each other for <br />food, mates, water and space<br />Examples<br />Population of trout in a river<br />Population of bats living in a cave<br />Population of GI students in the classroom<br />
    • 8. COMMUNITY<br />A community is made of many groups of populations that interact in an area <br />Examples:<br />A forest: populations of trees, populations of mushrooms, populations of birds<br />A lake: populations of insects, populations of fish, populations of algae<br />
    • 9. ECOSYSTEM<br />An ecosystem includes all the living organisms in an area and all the non- living things that affect it <br />Examples:<br />Forest ecosystem includes grass, soil, wind, sunlight, animals<br />Ocean ecosystem includes fish, coral, rocks at the bottom, temperature of water<br />
    • 10. BIOSPHERE<br />The part of the Earth that supports all organisms, made up of all of the Earth’s ecosystems<br />Examples:<br />Made up of the water, land, living things and air<br />
    • 11. Levels of Organization<br />
    • 12. Oct.20/21 Science Journal<br />SJ: Why do you think the ecological model (in the note today) is a picture of circles within circles?<br />
