Study Notes

Introduction to Ecology Part 1

  • Ecology studies interactions between organisms and their environment, including relationships between biotic (living) and abiotic (nonliving) components.
  • The term "ECO" comes from the Greek "oikos," meaning house. Initiated by Ernst Haeckel in 1866, students should build vocabulary lists and note unfamiliar terms.

Vocabulary

  • Students should enhance their vocabulary using flashcards, Quizlet, and Google Docs; submissions of lists aren't mandatory, and pop quizzes may occur.

Biotic and Abiotic Factors

  • Ecosystems are influenced by biotic (living) and abiotic (nonliving) factors.
  • Biotic factors encompass all living things an organism interacts with (e.g., parasites, pathogens, food sources, competition, predators).
  • Abiotic factors include elements like temperature, humidity, pH, salinity, oxygen level, sunlight, soil type, rainfall, climate, and wind/precipitation.
  • These factors are essential in determining the distribution of organisms.
  • Temperature and water availability are key abiotic factors determining organism distribution

Levels of Ecological Organization

  • Ecological organization follows a hierarchical structure.
  • Starting from broad to specific levels: biosphere, ecosystems, communities, populations, and organisms.

The Biosphere

  • The biosphere encompasses all regions of Earth inhabited by life (land, water, and air).
  • All organisms are part of the biosphere.
  • Life is not evenly distributed; it is primarily found a few meters above the Earth's surface and in the ocean.
  • The biosphere extends 5-6 miles above the surface to the deepest parts of the ocean.

Ecosystems

  • Ecosystems are units that comprise all living organisms in a specific area, along with their abiotic environment.

Communities

  • A community encompasses all living organisms within a particular area.
  • Communities can contain thousands of different species, representing interacting organisms (e.g. the example of a pond ecosystem involving fish, insects, turtles, etc).
  • Ecologists use species richness and species evenness to assess biodiversity.

Populations

  • A population comprises all members of the same species living within a specific area.
  • Multiple species in a given area can constitute a community, with communities made up of many populations.

Organisms

  • Organisms are individual living entities.
  • Organismal scientists concentrate on the adaptations that enable organisms to overcome ecological challenges.

Quick Check

  • Students should number their paper from 1-8.
  • When provided with an image, identify the level of biological organization it represents.

Biomes of the World

  • A biome is a large terrestrial ecosystem characterized by specific soil types, climate, plants, and animals.
  • Biomes are shaped by abiotic factors.
  • Biomes can contain transitional zones with gradual changes in characteristics.
  • Biomes represent widespread interactions at different scales, from individual organisms to global patterns.
  • Tolerance is the ability for organisms to survive and reproduce in conditions that differ from their optimal conditions.

Climographs

  • Climographs show average monthly precipitation and temperature over a year.
  • Climographs are an important tool for determining what type of biome exists in a particular area.
  • They are generally based on 30 or more years of data and help identify different biome types.
