Ecosystem Dynamics

Ecosystem dynamics describes the complex web of interactions and processes that drive changes in ecological systems across multiple temporal and spatial scales. This fundamental concept integrates population ecology, energy flow, and biogeochemical cycles to explain how ecosystems maintain stability while constantly evolving.

Core Components

Biotic Interactions

• species interactions including:
  • Competition
  • Predation
  • symbiosis
  • mutualism
• population dynamics
• community structure

Abiotic Factors

• nutrient cycling
• environmental conditions
• resource availability
• Physical habitat characteristics

Fundamental Processes

Energy Flow

• primary production
• trophic cascades
• decomposition
• nutrient transfer between organisms

Population Regulation

• density dependence
• carrying capacity
• frequency-dependent selection
• dispersal patterns

Stability and Change
