A new practical tool for deriving a functional signature for herbaceous vegetation

Abstract: Hypothesis: For any one time and place a ‘functional signature’ can be derived for a sample of herbaceous vegetation in a way that concisely represents the balance between the different clusters of functional attributes that are present among component species. Methods: We developed a spreadsheet‐based tool for calculating functional signatures within the context of the C‐S‐R system of plant functional types. We used the tool to calculate and compare signatures for specimen British vegetation samples which dif… Show more

“…This supports the assumption that the diversity of plant functional groups in receiving communities is a mechanism for resisting invasion (Theoharides and Dukes 2007). the relative abundance of Competitors, Stress-tolerants and Ruderals in a given species pool), which is based on Grime's (1977) classification and is related to gradients of stress and disturbance, can be used to indicate levels of resistance, resilience, eutrophication and dereliction (Hunt et al 2004). For plant invasion, the integrative power of the 'C-S-R functional signature' (i.e.…”

“…coordinates in “C‐S‐R space” providing a numerical index for the degree of adaptation to a strategy; cf . Hunt et al., ), moisture preference as indicated by Ellenberg F ‐value (Ellenberg, , adjusted by Hill, Mountford, Roy, & Bunce, ), and the dispersal traits plant life span (annual/perennial), seed buoyancy (% seeds afloat after 1 week in water), seed mass (g) and seed terminal velocity (m/s) (from the LEDA traitbase, Kleyer et al., ). For the in‐stream vegetation we classified species using the vegetative units of vascular plant species of the functional habitat classification by Harvey, Clifford, and Gurnell (), grouping growth forms by their association with (a) fast flow: trailing vegetation, species rooting in the bank but trailing over the water (like Agrostis stolonifera or Nasturtium officinale ); (b) intermediate fast flow: submerged fine‐leaved macrophytes, submerged species with leaves at least 4 times longer than wide ( Potamogeton pectinatus or Ranunculus ssp.…”
