Ecological Traits and Phylogeny of Turtles
Description
An ecological trait dataset for turtles. The dataset was derived from the recently published ReptTraits dataset (Oskyrko et al., 2024), extracting species classified under the major group Testudines (comprising 361 species). Only ecological traits with more than 50% of the species having trait records were retained. The phylogeny of turtles was derived by pruning from the maximum clade credibility tree with 288 tips provided in Thomson et al. (2021). Only those species that are present in both the ReptTraits dataset and the turtle phylogenetic tree were selected. Ultimately, the dataset comprised 240 species, encompassing 5 morphology traits, 2 behaviour traits, 2 life history traits, 5 habitat variables, and 2 variables concerning species conservation status.
