Krásivčí vlastnosti a krásivčí společenstva (DP) (METODY (svetlo…

- - - - Huston named this the selection probability effect, whereby the probability of including ( “ selecting ” ) any particular species in an experimental community increases as a function of species richness. (Cardinale 2011).
      - These authors separately argued that diversity effects on producer biomass were more likely driven by the presence of highly productive species that dominate processes in diverse communities.(Cardinalle 2011).
- - - - The process of community assembly should thus be considered as involving three different timescales:
        
        a rapid ecological timescale corresponding to community dynamics following species invasion;
        
        a slow immigration timescale corresponding to the arrival of individuals from the main source of species;
        
        a slow timescale corresponding to species (co)evolution in-between immigration events.

      - do comm.ass spadají vlivy imigrace z lokálního species poolu a koevoluce. První či druhé může být v daném společenstvu různě důležitým vlivem.

    - - diverzita bere v úvahu i rozdíly v početnosti (evenness)
    - - the probability of the most productive species becoming dominant
    - - refers to the phenomenon that species in the same ecosystem fill similar roles, which results in a sort of "insurance" in the ecosystem.
      - The concept of functional redundancy implies that species loss is compensated by other species contributing similarly to functioning. Functional redundancy can be revealed by the relationship between biodiversity and ecosystem functioning (e.g., biomass growth). The functioning of an ecosystem remains unaffected if redundant species are removed but decreases if the removed species have unique roles. (Fetzer 2015)
    - - is a measure of the number of functionally disparate species within a population (e.g. different feeding mechanism, different motility, predator vs prey, etc.
    - - are defined as morpho-physiophenological traits which impact fitness indirectly via their effects on growth, reproduction and survival. Notice that is definition is not specific to species. Since larger biological organizations grow, reproduce and sustain just as individual organisms do, functional traits can be used to describe ecosystem processes and properties as well.[9] To distinguish between functional traits at different scales, the classification scheme adopts the following nomenclature. Individual organisms have Ecophysiological traits and life-history traits; populations have demographic traits; communities have response traits; and ecosystems have effect traits.[9] At each level, functional traits can directly and indirectly influence functional traits in the levels above or below them.[9] For example, when averaged over an ecosystem, individual plants' heights can contribute to ecosystem productivity or efficiency.
        
        zdroj: wikipedie, podle Viole 2007 Let the concept of the trait be functional!
    - - compositional stability
  - - - the biomass of diverse polycultures only rarely exceeds that of the single most productive species in a community

      - Transgressive overyielding occurs when a mixture yields more than any monoculture of the compo- nent species. (Drake 2003)

- - - - Toto lze merit CAFE approachem (Bannar-Martin 2018)
        
        btw CAFE nezahrnuje evenness! (jenom SR, ne SD). ale zato přímo reflektuje vliv daného druhu, takže evenness je součástí (jednou z příčin) tohoto vlivu.
        
        CAFE approach je dobrej, protože se v něm odráží i evenness.
        
        zahrnout evenness je důležité (Hillebrand 2008)
