Phylogenetic Data for Percichthyidae and related groups

The following clades are being generated as part of my PhD work on the biogeography of Percichthyidae. They tend to be updated regularly as I gather more sequence data. At this point all trees are based on cytochrome B data for the entire gene (1140 bases). Please do not use or copy these trees to anywhere else, they are only preliminary, and hence are very likely to change as more data is accumulated. Additionally, most of the sequences this is based on have not been thoroughly checked for reading errors. There are largely being placed here so others who have contributed to collection of samples and in other ways can see the progress.

Percichthyidae neighbour joining tree based on the entire cyt. B gene. Numbers represent the levels of sequence divergence between branches (Tamura-Nei distances).

Percichthyidae consensus tree based on the entire cyt. B gene. It is based on a parsimony analysis with 1000 random additions.

Percichthyidae fast bootstrap tree (with 100 replicates) based on the entire cyt. B gene to show the most robust groupings and their levels of support.

Locality data for pygmy perches based on the last two numbers of the field number (ie, 0024 = 24 on the figure). Not all samples on the figure are contained in the trees below as they are yet to be sequenced. Light blue rivers are drainage patterns to -500 meters.

Pygmy perch neighbour joining tree based on entire cyt b gene. Distances are Jukes-Cantor.

Pygmy perch consensus tree based on a heuristic search (100 replicates-9 trees) based on entire cyt b gene.

One of nine pygmy perch parsimony trees based on a heuristic search (100 replicates) based on entire cyt b gene.

Pygmy perch fast bootstrap tree based on 100 replicates for the entire cyt b gene.

Pygmy perch S7 neighbour joining tree based on 681 bases of the first intron in the S7 gene (all gaps and ambiguous characters were removed). Ignore the trees rooting as it is somewhat meaningless, but makes graphic display easier. Distances are Jukes-Cantor. Note that Edelia obscura and Nannoperca australis have much larger genetic distances relative to cytochrome b data.

Pygmy perch S7 parsimony tree (1000 reps) based on 681 bases of the first intron in the S7 gene. Midpoint rooting was used.

Pygmy perch S7 fast bootstrap tree (1000 reps) based on 681 bases of the first intron in the S7 gene. Ignore the trees rooting as it is somewhat meaningless, but makes graphic display easier.

More will be coming as the results flow in.
