Study Notes
Temperature and Heat
- Temperature: Measures average kinetic energy of molecules in a substance.
- Heat: Describes the kinetic energy within a mass of a substance.
Dryas Flowers
- Dryas flowers have a parabolic shape to concentrate solar energy on reproductive structures.
- Insects warm themselves on these flowers, aiding pollination.
Importance of Temperature
- Temperature influences chemical reaction rates, crucial for processes like photosynthesis and respiration.
- Organisms are adapted to a specific temperature range for optimal functioning.
Climate Interactions
- Macroclimate: Long-term weather conditions in a region.
- Microclimate: Short-term climatic variation occurring over small scales influenced by local landscape features.
Influences on Microclimate
- Factors include altitude, aspect (direction faced), vegetation, ground color, and presence of boulders.
- Water and soil characteristics limit temperature fluctuations in aquatic environments and animal burrows.
Altitude and Temperature
- Cooler temperatures at higher elevations due to decreased atmospheric pressure and reduced air density.
- Less atmosphere at higher elevations means decreased heat retention.
Aspect and Microclimates
- Topography creates shaded and sunlit areas; north-facing slopes in the Northern Hemisphere are cooler and moister.
- Southern Hemisphere follows a similar pattern with southern aspects receiving less sunlight.
Vegetation and Microclimates
- Plants provide shade, creating cooler microclimates; vegetation types can significantly affect local thermal environments.
Ground Color Effects
- Different ground colors, such as white or black sand beaches, create varying microclimatic conditions.
Boulder and Burrow Impacts
- E.B. Edney’s research showed stones can create significant temperature differences; Ligia oceanica thrived under stones at higher temperatures compared to open air.
- Animal burrows typically feature moderated temperatures compared to surface conditions.
Aquatic Temperature Stability
- Water's high specific heat contributes to thermal stability, absorbing much heat without significant temperature changes.
- It requires significantly more energy to heat water compared to an equal volume of air, leading to consistent aquatic temperatures.
