Fossil calibrated molecular phylogenies of Southern cave weta

Aim: The biota of continents and islands are commonly considered to have a source-sink relationship, but small islands can harbour distinctive taxa. The distribution of four monotypic genera within the southern subfamily Macropathinae on young oceanic islands indicates a role for long-distance dispersal and extinction. We used molecular dating to estimate the timing of the southern radiation and infer potential processes involved.
Location: Subantarctic islands, South Africa, South America, Australia, Aotearoa/New Zealand.
Taxon: Southern hemisphere camel crickets subfamily Macropathinae within the Orthopteran family Rhaphidophoridae (Cave crickets/camel crickets/cave weta/tokoriro).
Methods: Phylogenetic relationships were inferred from whole mtDNA genomes and nuclear sequences (45S cassette; four histones). We used a fossil and one palaeogeographic event to calibrate a molecular clock analysis.
Results: We confirm that neither the Australian nor Aotearoa/New Zealand Rhaphidophoridae f..., We used high-throughput sequencing of whole genomic DNA to assemble entire mitochondrial genomes and multi-copy nuclear markers for molecular phylogenetics., Applications needed to access the files are: Excel and Geneious prime, # Fossil calibrated molecular phylogenies of Southern cave weta
