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.
