Ecological Dominance Shift

A Ecological Dominance Shift is a biological process that involves species replacement in key ecological roles (affecting ecosystem functions and energy flows).

• Context:
  • It can typically alter Ecosystem Structure through competitive advantage.
  • It can typically reorganize Trophic Level through replacement dynamic.
  • It can typically transform Habitat Composition through dominant species influence.
  • It can typically reshape Resource Utilization Pattern through ecological efficiency.
  • It can typically follow Environmental Disruption through adaptive response.
  • ...
  • It can often facilitate Evolutionary Pathway through selection pressure.
  • It can often provide Ecosystem Service Change through functional replacement.
  • It can often implement Biodiversity Restructuring through competitive exclusion.
  • It can often support New Adaptation Cascade through trophic relationship.
  • ...
  • It can range from being a Localized Ecological Dominance Shift to being a Global Ecological Dominance Shift, depending on its geographic extent.
  • It can range from being a Rapid Ecological Dominance Shift to being a Gradual Ecological Dominance Shift, depending on its temporal progression.
  • ...
  • It can have Keystone Species Replacement for ecosystem stability.
  • It can have Energy Flow Redirection for productivity alteration.
  • It can have Habitat Modification for ecological niche creation.
  • ...
• Examples:
  • Ecological Dominance Shift Categories, such as:
    • Vertebrate Dominance Shifts, such as:
      • Dinosaur-Mammal Ecological Dominance Shift for post-extinction terrestrial vertebrate repopulation.
      • Marine Reptile-Cetacean Ecological Dominance Shift for oceanic apex predator replacement.
    • Plant Community Dominance Shifts, such as:
      • Forest-Grassland Ecological Dominance Shift for herbivore adaptation catalyst.
      • Fern-Angiosperm Ecological Dominance Shift for post-extinction floral recovery.
  • Anthropogenic Ecological Dominance Shift Categories, such as:
    • Human-Driven Ecological Dominance Shifts, such as:
      • Wild-Domestic Ecological Dominance Shift for agricultural landscape transformation.
      • Natural-Urban Ecological Dominance Shift for human habitat expansion.
  • ...
• Counter-Examples:
  • Ecological Succession, which lacks dominant taxon replacement.
  • Community Composition Change, which lacks fundamental niche restructuring.
  • Invasive Species Impact, which lacks evolutionary time scale.
