Ecological Disturbance02:26

Ecological Disturbance

21.1K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Ecological Succession02:17

Ecological Succession

21.5K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Ecological Niches

26.6K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

What is Natural Selection?

129.0K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Community Based Intervention

479
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Theoretical Biology

Background:

  • Ecological communities comprise multiple interacting species.
  • Interconnected ancestral histories influence community dynamics.
  • Previous models often simplify species interactions and environmental influences.

Purpose of the Study:

  • To develop a novel model for ecological community ancestral history.
  • To incorporate selection based on abiotic and biotic factors.
  • To explore metacommunity structure and its evolutionary consequences.

Main Methods:

  • Utilized coalescent and ancestral graph theory.
  • Defined a forward-time percolation process for community evolution.
  • Developed a backward-time graphical model for large populations.

Main Results:

  • Derived expectations for phenotypic variation and trait-environment covariances.
  • Quantified the effects of drift, genealogy, and selection.
  • Compared phenotypic diversity under neutrality versus stabilizing selection.

Conclusions:

  • The model provides insights into the genetic and phenotypic structure of ecological communities.
  • Selection and genealogical relationships are key drivers of community evolution.
  • The framework allows for studying trait evolution in complex ecological settings.
