A census is a survey taken to gather information about a certain group – marine life!
Ecology: Levels of Organization
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' Phuo Yang Mountain, is one of 1,068 new species identified in the Greater Mekong from 1997 to 2007 in the WWF report, "First Contact in the Greater Mekong."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 />
Ecology is the study of the relationships between the natural world and all the living and non-living things in that environment<br />
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 />
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.

Levels of organization in Ecology<br />Biosphere<br />Ecosystem<br />Community<br />Population<br />Individual (species)<br />
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 />
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 />
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 />
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 />
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 />
