This dataset corresponds to the following publication:
Osuri, A. M., Chakravarthy, D., Mudappa, D., Raman, T. R. S., Ayyappan, N., Muthuramkumar, S., and Parthasarathy, N. 2017. Successional status, seed dispersal mode and overstorey species influence tree regeneration in tropical rain-forest fragments in Western Ghats, India. Journal of Tropical Ecology 33: 270-284. DOI: 10.1017/S0266467417000219

This is version 2 of the dataset with data provided in CSV format. Version 1 (http://datadryad.org/resource/doi:10.5061/dryad.vd0nn) contains the same data in .xlsx format.

The download includes a compressed folder that contains three CSV files whose contents are described below:
1) osuri_et_al_trees_regen_data.csv
2) osuri_et_al_trees_adult_data.csv
3) osuri_et_al_trees_traits_data.csv

-----File 1: "osuri_et_al_trees_regen_data.csv"-----
Description: The file contains records of all seedlings and saplings (1-5 cm diameter at breast height of 1.3 m, dbh) and larger trees (>5 cm dbh) recorded within 5m x 5m regeneration plots that were nested within 20m x 20m adult tree plots in two continuous forests and two forest fragments. Data were filtered during analysis to retain only seedling and saplings, defined as individuals with effective diameter <=5 cm.  

Column names and descriptions:
X: Row index
Site: Name of forest site
type: Habitat type, either "Cont" (continuous forest) or "Frag" (forest fragment)
P.No: An unique plot no. assigned to each 20m x 20m adult tree plot within each site
Q.no: An unique number assigned to each of four 10m x 10m quarters within each adult plot
nos: An unique number assigned to each individual seedling, sapling or tree within each site. 
old_code: Species codes used at the time of data collection (refer to traits data file for full species names)
species: Revised species codes consistent with current taxonomy
dbh, dbh.1 to dbh.34: Diameter at breast height of single- (dbh) and multi-stemmed (dbh - dbh.34) individuals, measured in centimetres (cm)    
eff.dbh: Effective diameter at breast height (cm)- calculated as ((dbh)^2 +(dbh.1)^2 +...+(dbh.34)^2)^(1/2), 
P.ID: Unique plot ID created by combining columns Site and P.No
-----

-----File 2: "osuri_et_al_trees_adult_data.csv"-----
Description: The file contains records of all adult trees >= 30 cm girth at breast height of 1.3 m (gbh) recorded within adult tree plots across two continuous forests and two forest fragments.

Column names and descriptions:
X: Row index
Site: Name of forest site
type: Habitat type, either "Cont" (continuous forest) or "Frag" (forest fragment)
P.No: An unique plot no. assigned to each 20m x 20m adult tree plot within each site
Q.no: An unique number assigned to each of four 10m x 10m quarters within each adult plot
nos: An unique number assigned to each individual tree within each site. 
old_code: Species codes used at the time of data collection (refer to Appendix A of the main paper for full species names)
species: Revised species codes consistent with current taxonomy
gbh, gbh.1 to gbh.34: Girth at breast height of single- (gbh) and multi-stemmed (gbh - gbh.34) individuals, measured in centimetres (cm)   
P.ID: Unique plot ID created by combining columns Site and P.No
-----

-----File 3: "osuri_et_al_trees_adult_data.csv"-----
Description: This file contains names and traits of species encountered as seedlings and saplings (1-5 cm dbh) in regeneration plots in continuous and fragmented rain forests. * next to species names indicates shrub species recorded in regeneration plots but not included in the present analysis. See Appendix 1 of the main paper for more information and sources for the species traits information.  
Sl.No.: Serial number
Code: Species code consistent with current taxonomy
Species: Species name and family consistent with current taxonomy  
Successional.status: Species successional status: O = Old-growth species; E = Early-successional species; I = Introduced species
Seed.dispersal.mode: Species seed-dispersal mode: B = Bird; M = Mammal; BM = Bird and mammal; G = Gravity; W = Wind; U = Unknown
Seed.size: Species seed size: L = Large (>3 cm); M = Medium (1-3 cm); S = Small (<1 cm)
Wood.density: Species wood density (g cm^-3)
Max.adult.height: Species maximum adult height (m)
