Mortality of lianas (vines) in tropical forests

Description

This study is part of the project "Diversity and dynamics of vascular epiphytes in Colombian Andes" supported by COLCIENCIAS (contract 2115-2013). The data corresponds to the first large-scale assessment of vascular epiphyte mortality in the neotropics. Based on two consecutive annual surveys, we followed the fate of 4247 epiphytes to estimate the epiphyte mortality rate on 116 host trees at nine sites. Additional variables were taken from the area of study in order to find relationships with epiphyte mortality.

Usage

Format

The data frame contains four variables as follows:

PlotSite: Municipality name of the 9 study sites
Y.Plot: Latitude of the plot in decimal degrees
X.Plot: Longitude of the plot in decimal degrees
PhoroNo: ID number of the sampled host trees in each site
EpiFam: Epiphyte taxonomic family
EpiGen: Epiphyte taxonomic genus
cf.aff: Abbreviations of Latin terms in the context of taxonomy. cf. "confer" meaning "compare with". aff.: "affinis" meaning "similar to".
Species: Epiphyte (morpho) species name
Author: Author of the scientific name
EpiAzi: Azimuth of the epiphyte individual on each host tree
BraAzi: Azimuth of the branch in which the epiphyte individual was found
EpiDisTru: Distance in meters from the trunk to the epiphyte attachment site on a branch
EpiSize: Estimated size of the epiphyte individual, in cm.
EpiAttHei: Epiphyte attachment height in meters
Date0: Date of the first census
Date1: Date of the final census
Location: Section (roots, trunks, branches) of the host tree in which theepiphyte individual was found
Mortality: Dichotomous variable. 0 if the epiphyte individual was dead in the final census and 1 if otherwise

ATR_bio7: Annual temperature range in the plot (10 celsius degrees)
AET: Actual evapotranspiration in the plot (mm yr-1)
BasAre: Basal area of trees with DBH major or equal to 5 cm (AB) in the plot (m^{2}/ha)
BasAre5_10: Basal area of trees with greater or equal than 5 DBH and less than 10 cm in the plot (m^{2}/ha)
