Non-equilibrium dynamics and non-neutral processes, such as
trait-dependent dispersal, are often missing from quantitative island
biogeography models despite their potential explanatory value. One of the
most influential non-equilibrium models is the taxon cycle, but it has
been difficult to test its validity as a general biogeographical
framework. Here, we test predictions of the taxon-cycle model using six
expected phylogenetic patterns and a time-calibrated phylogeny of
Indo-Pacific Odontomachus (Hymenoptera: Formicidae: Ponerinae), one of the
ant genera that E.O. Wilson used when first proposing the hypothesis. We
used model-based inference and a newly developed trait-dependent dispersal
model to jointly estimate ancestral biogeography, ecology (habitat
preferences for forest interiors or “marginal” habitats, such as
savannahs, shorelines, disturbed areas, etc), and the linkage between
ecology and dispersal rates. We found strong evidence that habitat shifts
from forest interior to open and disturbed habitats increased
macroevolutionary dispersal rate. In addition, lineages occupying open and
disturbed habitats can give rise to both island-endemics re-occupying only
forest interiors and taxa that re-expand geographical ranges. The
phylogenetic predictions outlined in this study can be used in future work
to evaluate the relative weights of neutral (e.g., geographical distance
and area) and non-neutral (e.g., trait-dependent dispersal) processes in
historical biogeography and community ecology.
Odontomachus_MultilocusThis is the multi-locus (six genes) alignment with
112 Odontomachus specimens. This dataset has been used to infer the
phylogenetic relationships within the genus
Odontomachus.Odontomachus_MultiMarker.nexSingle-gene datasetsThese are the
alignments of each of the six loci used in the study. These files have
been run in MrBayes v3.2.3.SingleGene.zipBEAST xml filesThese are three
relevant files for time-calibration analyses of Odontomachus. The
multi-locus alignment with one specimen per species is in nexus format,
whereas two xml files can be found, one following the calibration density
approach (minimum ages of fossils) and the second following the Fossilized
Birth Death model.BEAST.zipBioGeoBEARSThese are all relevant files to run
the BioGeoBEARS R script available at
http://phylo.wikidot.com/biogeobears#toc31. The input files were used for
biogeographical analyses of Odontomachus, including stochastic mapping and
the the trait-dependent biogeography model.Sampling localitiesSampling
