Study Notes
Climate Factors
- Ocean temperature impacts climate patterns.
- Elevation affects temperature; higher altitude leads to cooler and thinner atmosphere, increasing UV radiation exposure.
Microclimates
- Defined as localized climate conditions differing from their general surroundings.
- Example: Lichens thrive in specific microhabitants due to unique microclimatic conditions.
Understanding the Supernatural
- Supernatural phenomena cannot be observed or measured using scientific methods.
- Scientific approach involves:
- Observation
- General ideas (theory/law)
- Predictions/hypotheses
- Specific observations/experiments
Fundamental Principles
- Environments are diverse and heterogeneous.
- Resources are often finite and unevenly distributed.
- Organisms interact diversely with their environment and each other.
- Distribution of organisms varies across regions.
- Contingency refers to conditions relying on specific factors.
- All organisms have a lifespan (mortality).
Causation in Ecology
- Causation chains represent sequences of ecological events culminating in outcomes.
- Proximate causation identifies immediate causes, while ultimate causation explores evolutionary reasons behind traits.
Climate vs. Weather
- Weather encompasses short-term conditions like temperature and humidity.
- Climate refers to long-term trends and average conditions.
Sunlight Intensity and Earth's Tilt
- Sunlight is less intense at higher latitudes due to oblique angles; more intense near the equator.
- Earth's axial tilt causes variance in solar energy distribution.
Atmospheric Circulation
- Warm air rises at the equator due to intense heating, leading to precipitation.
- Air descends and cools at 30°N and 30°S, creating dry conditions; example includes the Sahara Desert.
- Convection cells driven by solar radiation influence weather patterns.
Ocean Dynamics
- Ocean currents are affected by Earth's rotation and wind patterns.
- Gyres circulate heat in oceans through warm and cold currents.
Topographical Effects on Climate
- Mountain slopes can create distinct microclimates; windward sides are typically moist while leeward sides are dry.
- North-facing sides (in the Northern Hemisphere) receive more sunlight leading to varied vegetation.
Biomes Overview
- Major biomes include tropical forests, savannas, grasslands, chaparral, tundra, and boreal forests.
- Aquatic zones classified into intertidal, continental, photic (photosynthesis possible), and aphotic (no light).
Species Distribution Factors
- Abiotic factors: temperature, humidity, non-living environmental conditions.
- Biotic factors: interactions with other species, food availability, predators.
- Species mobility influenced by ancestral regions.
Demography
- Population studies analyze changes over time, focusing on birth/death rates and immigration/emigration trends.
- Density indicates crowding in a specific area.
Survivorship Curves
- Type I: High survival in youth; low in old age.
- Type II: Uniform survival across all ages.
- Type III: Low survival early, high in later stages.
Reproductive Strategies
- Fecundity measures offspring quantity under ideal conditions; varies by species (e.g., fish).
- Biological potential reflects maximum reproductive capacity of a species.
- Potential range includes all habitats that could support a species; actual range is the current living area.
Population Dispersion Patterns
- Uniform dispersion: individuals evenly spaced.
- Clumped dispersion: individuals grouped in patterns.
- Random dispersion: individuals spread without a specific arrangement.
Population Growth Dynamics
- Population size indicators: if growth ratio equals one, the population remains stable; less than one indicates decline, more than one indicates growth.
- Exponential growth: population size increases without resource limits.
- Logistic growth: initial rapid growth slows down as it nears environmental carrying capacity, influenced by resource limitations.
