iNEXT (version 2.0.8)

plant: Three coastal dune plant communities

Description

The datset contains 272 random vegetation plots sampled in the period 2002~2009 in the three most typical foredune habitats: (i) upper beach and embryo dunes (Embryo), (ii) mobile dunes and (Mobile) (iii) transition dunes (Transition). For further details see Carboni, Santoro & Acosta (2010, 2011).

Usage

data("plant")

format

A list 3: $Embryo is a data frame with 46 species (rows) on the following 70 sites (columns). $Mobile is a data frame with 46 species (rows) on the following 131 sites (columns). $Transition is a data frame with 46 species (rows) on the following 71 sites (columns).

Details

Random sampling was performed using georeferenced points extending over 250 km along the Tyrrhenian coast and distributed in several study sites including most of the best conserved remnant dune systems of the region (for further details see Carboni, Santoro & Acosta 2010, 2011). At each random point, all vascular plants sampled in a square 2 x 2 mplot were listed together with a visual estimate of each species using a 10%-interval rank scale.
