    - - Considering that assemblyprocesses acting on natural communities may differ depend-ing on the spatial scale considered, separating functionaldiversity in within-community (˛) and among-community(ˇ) components will improve the detection of all the pro-cesses acting on community assembly. Here, ˛ represents thediversity of trait values within one community, whereas ˇ rep-resents how diverse are species trait values among differentcommunities (Bryant et al., 2008; De Bello et al., 2009; Lozuponeand Knight, 2005; Swenson, 2014).
  - - - functional redundancy, whichrepresents the similarity among species in functional terms(De Bello et al., 2007), influencing the resilience of communi-ties (Naeem, 1998; Pillar et al., 2013). Functionally redundantspecies are expected to play similar roles in ecosystem pro-cesses. Therefore, it is fundamental to select the species traitsinvolved in the ecosystem process for correctly estimatingfunctional redundancy (Pillar et al., 2013).
      - When assessing FD, a large number of functional traits increase the ability to detect functional differences between species (it increases the ‘trait space’ in which they can vary), reducing the impact of species identity and the likelihood of classifying species as functionally redundant (Petchey & Gaston 2002b).
        
        "kdyz bych vybrala vic traitu, asi vysvetlim jeste vic variability." (ale s mnozstvim vysvetlene variability jsem celkem spokojena.)

        . Of course, this is not to say that the proposed criteria will result in a single, agreed-upon measure of FD. Summarizing a large multivariate data set such as a trait matrix into a single diversity figure inevitably results in some loss of information. Therefore, a perfect FD measure does not exist. Since different diversity measures have been defined based on distinct objectives and motivations, their mathematical formulation can be expected to influence the sign and strength of their connection with the functioning and organization of biological communities.
      - with functional richness performing the worst out of all measures of biodiversity (Flynn et al. 2011)
      - Calculating functional diversity requires several key decisions. We used the metric FD proposed by Petchey and Gaston (2002) because it exactly parallels PD, accommodates a variety of data types, and has been widely applied as a measure of functional diversity. --flynn 2011
- - - - In general, a positive effect of biodiversity is expected on the stability of ecosystem properties (Tilman 1996; Naeem & Li 1997; Yachi & Loreau 1999; Hooper et al. 2005), and qualitative reviews have suggested that such effects on the variance in processes (stability) may be stronger than the effects on means (stocks and fluxes; Srivastava & Vellend 2005). The quantitative results from our meta-analysis do not support this view, rather indicating that biodiversity effects on disturbance buffering are dependent on the nature of the disturbance. Thus, while biodiversity effects on buffering of nutrient perturbations and invading species were positive, biodiversity effects on buffering influences of warming, drought or high environmental variance were neutral or slightly negative.
- - - - RŮZNÉ VELIKOSTI SE NEMAJÍ RÁDY?
      - PŘI VYŠŠÍCH ÚROVNÍCH ASPEKTŮ SLOŽITĚJŠÍ ROCK-SCISSORS INTERAKCE?
- - - - kdyz je to nad nulou, tak je to jasnej dukaz. je to velka podminka a proto slabej test.
    - - mixture potrebuje narust k OY tim vic, cim vic druhu je ve spolecenstvu a cim vetsi je jejich variance.
        
        varianci mame velikou = vztah se SR atd je silny.
    - - monokultury a polykultury se casto lisej. proto muze jina metrika byt lepsi. (a navrhuje).
- - - - FD - řasa bouchač. a už to ve vyšších SR nedá. liší se v "invazibilitě". a když je jich pak víc různých, tak to daj aspoň nějak.
      - invazibilita? další věci?
      - ale stejně se to vrací k tomu, PROČ SE TO OBRACÍ?
