Here we outline the steps of the integrative processing of sample metadata, sample character data and their taxon assignment, as it has been developed and is being implemented in the EDIT Platform.
When tested with additional samples, characters that are critical for species diagnosis may be revealed to be polymorphic and not fixed [33] and it is possible that the key we developed will fail to distinguish species when tested against additional samples.
In our phylogenetic analysis based on maximum parsimony, taxon sampling, characters and coding largely follow those of Mallatt and Holland [ 11].
Bootstrap support for this clade rose for all five analytical methods when the number of sampled characters was nearly doubled (data set A [27 taxa × 10 genes] versus B [27 taxa × 21 genes]; Table 2).
No variation of taxon sampling, character inclusion, or methodology resulted in the placement of the fleas within Mecoptera.
Although the effectiveness of sampling techniques influences which are used, other factors that determine the choice of sampling techniques include the site of sampling, size of the surface to be sampled, character of the surface (porous or nonporous), need to quantify the results, and preference and specialization of the laboratory where the test is done.
For each specimen for each sample decaying characters were scored 0.5 and lost characters scored 1.0; the sum of these was divided by the number of observed characters to give the proportion of decay.
We examined all aligned gene sequences for potential indels across the entire taxon sample, scoring characters as 1 for presence or 0 for absence of a sequence stretch.
We did not assess different substitution models for different partitions within genes given that simulations show that overly simple models may be inappropriately selected when a small sample of characters is tested [ 73].
Taxon sampling, nucleotide character type, and phylogenic methods all influence inferred phylogeny, as shown by several earlier studies that reveal different relationships within our named sections (Bäumler et al. 1998; Kingsley and Bäumler 2000; Zou et al. 2013).
