Information from Literature

Summary

 

INFORMATION FROM LITERATURE quantifies how different dispersal modes of a plant species are categorized in published literature.

 

 

Trait description

 

INFORMATION FROM LITERATURE is coded in eight variables which quantify how often an assessment of the addressed dispersal mode was found in literature (No. 1 in Tab. 1) and how high the proportion of citations for the seven considered dispersal modes was (No. 2-8 in Tab. 1). Only dispersal modes and vectors with a high potential for long-distance dispersal are considered.

We recommend using the proportions only if at least five citations per species are available.

Description

1

citation_total

integer

Number of citations how often an assessment of any of the considered dispersal modes was found in literature.

2

citation_prop_ane

continuous [0-1]

Proportion of the citations for anemochory, i.e. dispersal by wind. These data do not include boleochor species.

3

citation_prop_dyso

continuous [0-1]

Proportion of the citations for dysochory (including stomatochory), i.e. dispersal by scatterhording animals.

4

citation_prop_endo

continuous [0-1]

Proportion of the citations for endozoochory, i.e. dispersal by animals after feeding and digestion.

5

citation_prop_epi

continuous [0-1]

Proportion of the citations for epizoochory, i.e. dispersal on the coats or hooves of animals.

6

citation_prop_hem

continuous [0-1]

Proportion of the citations for hemerochory, i.e. dispersal by humans and human activities.

7

citation_prop_hydro

continuous [0-1]

Proportion of the citations for hydrochory, i.e. dispersal on the surface of water.

8

citation_prop_other

continuous [0-1]

Proportion of the citations for other dispersal modes that offer the possibility of long-distance dispersal, e.g. bythisochory or chamaechory.

Data Sources

 

The raw data used for the calculations are mainly taken from DIASPORUS (Bonn et al., 2000), BIOPOP (Poschlod et al., 2006), LEDA (Kleyer et al., 2008) and unpublished data.
