  1. 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: Introduction to Ecology: ‘Decade of Discovery’ 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: Article from news website From: Oct. 4, 2010 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:

  2. Ecology is the study of the relationships between the natural world and all the living and non-living things in that environment

  3. Levels of organization in Ecology • Biosphere • Ecosystem • Community • Population • Individual (species)

  4. SPECIES • Similar organisms that can successfully reproduce among themselves in their natural environment • THIS MEANS: they produce offspring that can reproduce as well Examples: Species of frog: water frog, red-eyed tree frog • Species of horse: Clydesdale horses, Andalusian horses

  5. POPULATION • A population is made of many of the SAME KIND of species that live in the same area • Compete with each other for food, mates, water and space Examples • Population of trout in a river • Population of bats living in a cave • Population of GI students in the classroom

  6. COMMUNITY • A community is made of many groups of populations that interact in an area Examples: • A forest: populations of trees, populations of mushrooms, populations of birds • A lake: populations of insects, populations of fish, populations of algae

  7. ECOSYSTEM • An ecosystem includes all the living organisms in an area and all the non- living things that affect it Examples: • Forest ecosystem includes grass, soil, wind, sunlight, animals • Ocean ecosystem includes fish, coral, rocks at the bottom, temperature of water

  8. BIOSPHERE • The part of the Earth that supports all organisms, made up of all of the Earth’s ecosystems Examples: • Made up of the water, land, living things and air

  9. Levels of Organization

  10. Science Journal • SJ: Why do you think the ecological model (in the note today) is a picture of circles within circles?
