Koutsidi, Moukas, Tzanatos: 23 biological traits of 235 species

This file contains traits data for 235 Mediterranean nekton species. There are data on 23 traits; the data are presented in a continuous, range (minimum & maximum) or a categorical form. In the latter case, for each trait, 2-6 trait categories/modalities exist and each species has been assigned to only one modality per trait.


The Excel file has 6 worksheets:

(1) Continuous&range_235species: This worksheet contains information on the continuous traits (longevity, age-at-maturity, fecundity, maximum length, trophic level, optimal depth, optimal temperature). For traits of the range type (fecundity, depth, trophic level and temperature) the mean value is provided together with the other traits. To the right of the table the minimum and maximum of range type traits by species is presented. All 235 species, even with incomplete information (NA) on all continuous traits are presented.


(2) Continuous&range_205species: This worksheet contains information on the continuous traits (longevity, age-at-maturity, fecundity, maximum length, trophic level, optimal depth, optimal temperature). For traits of the range type (fecundity, depth, trophic level and temperature) the mean value is provided together with the other traits. To the right of the table the minimum and maximum of range type traits by species is presented. Only the species with complete information (205 species) on continuous traits are presented (however, some NAs can still be found in the case of minimum or maximum if only the mean or the maximum value of the trait has been documented).


(3) Categorical_23traits_235species: This worksheet is a presence/absence (1/0) matrix of 235 species by 23 traits using 81 trait categories (or modalities). All species, even with incomplete information (NA) on all 23 traits are presented.


(4) Categorical_23traits_205species: This worksheet is a presence/absence (1/0) matrix of 205 species by 23 traits using 81 trait categories (or modalities). For each trait only one modality is scored with a presence. Only the species with complete information (205 species) on all 23 traits are presented.


(5) reference_codes_per_trait: This worksheet is a matrix of the 235 species by 23 traits with one or more numbers representing a reference from which the information to fill in the trait information as data (shown in the previous worksheets) was taken.


(6) reference_list: This worksheet is a list of reference numbers and the corresponding full references.
