Study Notes
Ecology and Evolution Concepts
- Adaptation is a trait that enhances an organism's ability to survive and reproduce in a particular environment. Examples include the giraffe's long neck.
- A keystone species is a species whose presence significantly affects the ecosystem's structure and function. Sea otters are an example.
- Natural selection is the process where traits that improve survival and reproduction become more common over generations. An example is darker moths surviving better in polluted areas.
- Pioneer species are the first organisms to colonize a barren or disturbed environment. Lichens and mosses are examples.
- Selective forces are environmental factors influencing an organism's ability to survive and reproduce. Predation is an example.
- Primary succession occurs in environments without prior life or soil. Volcanic eruptions are an example.
- Secondary succession occurs in areas disturbed, but with existing soil and some organisms. Forest fires are an example.
- Late successional species dominate ecosystems later in succession, characterized by slower growth, greater competition, and longer lifespans. Oak trees are an example.
- Climax community is the stable, final community in ecological succession that usually remains unchanged unless disturbed. A mature oak forest is an example in a temperate climate.
- Carrying capacity is the maximum population size an environment can sustain. A lake may have a carrying capacity of 500 fish.
- Limiting resources are scarce resources restricting the growth, distribution, or abundance. Water is a limiting resource in deserts.
- Overshoot/dieoff occurs when a population exceeds its carrying capacity, then experiences a rapid decline. Deer populations might overshoot and die off if they consume all available vegetation, leading to a shortage of food.
Density Dependent/Independent Factors
- Density-dependent factors influence population growth based on population density. Disease spread is an example of a density-dependent factor.
- Density-independent factors affect populations regardless of their density, such as natural disasters. Wildfires are an example.
Soil Layers
- Soil layers include O (organic), A (topsoil), E (eluviation), B (subsoil), C (parent material), and R (bedrock).
- The darkest layers of soil, typically O and A horizons, are rich in organic matter.
- A horizons contain the most nutrients.
Soil Texture, Porosity, and Water Holding Capacity
- Soil texture describes the proportion of sand, silt, and clay particles.
- Porosity refers to the spaces between soil particles holding water and air.
- Water holding capacity is the amount of water soil can retain. Clay soil holds the most water, sandy soil the least.
Essential Nutrients for Plant Growth
- Essential nutrients include nitrogen, phosphorus, potassium, calcium, and magnesium.
Atmospheric Concepts
- The atmosphere has layers including troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
- The troposphere experiences decreases in temperature with increasing altitude. The stratosphere experiences increases in temperature.
Relationships Between Temperature and Density
- Warmer air is less dense than colder air. More dense air sinks, less dense air rises.
Global Wind Patterns and Rainfall
- Hadley Cells, Ferrel Cells, and Polar Cells are the primary atmospheric circulation cells.
- Precipitation is more frequent in the equatorial region due to warm air rising and cooling.
- The Coriolis effect deflects wind patterns, influencing global wind systems (trade winds, westerlies, and polar easterlies).
El Niño and La Niña
- El Niño is a climate pattern with warmer water in the central and eastern Pacific, disrupting weather patterns globally.
- La Niña is characterized by cooler temperatures than average in the central and eastern Pacific, also impacting global weather.
- Upwelling is the process that brings cold, nutrient-rich water from the deep ocean to the surface, supporting marine life.
