“…When the rule of progression is met, the ages of island formation can be used as calibrations for molecular dating analyses. Some taxa on the Hawaiian islands, such as Hypocosma moths [43], provide compelling examples of the progression rule. Nevertheless, colonization histories can sometimes be much more complex [44], potentially undermining the reliability of calibrations associated with island formation.…”

“…Some well-considered examples of normal priors being used for calibrations have been those based on island colonization [43] and those used to reflect the uncertainty in the timing of geological events [26]. By contrast, exponential priors might be appropriate when the age of a node is likely to be very close to the timing of a particular geological or climatic event [48].…”

Biogeographic calibrations for the molecular clock

et al. 2015

Molecular estimates of evolutionary timescales have an important role in a range of biological studies. Such estimates can be made using methods based on molecular clocks, including models that are able to account for rate variation across lineages. All clock models share a dependence on calibrations, which enable estimates to be given in absolute time units. There are many available methods for incorporating fossil calibrations, but geological and climatic data can also provide useful calibrations for molecular clocks. However, a number of strong assumptions need to be made when using these biogeographic calibrations, leading to wide variation in their reliability and precision. In this review, we describe the nature of biogeographic calibrations and the assumptions that they involve. We present an overview of the different geological and climatic events that can provide informative calibrations, and explain how such temporal information can be incorporated into dating analyses.

“…One of these groups (Hyposmocoma spp. ), is a hyper-diverse radiation of case-making species that can occur in relatively high densities and in a wide range of habitat types (Haines et al 2014). These characteristics suggest that this group may be somewhat resistant to certain types of invasive species pressures, but in this system they appeared to be very sensitive to ant presence (22.5 % incidence in samples with \5 ants vs. 3 % in samples with C5 ants).…”

Ecology of some lesser-studied introduced ant species in Hawaiian forests

Invasive ants can have strong ecological effects on native arthropods, but most information on this topic comes from studies of a handful of ant species. The ecological impacts of the many additional introduced 'tramp' ant species are largely unknown. In mesic upland forests of O'ahu, Hawai'i, ten species of introduced ants were found on four species of understory trees. However, these ants were generally uncommon and occurred at relatively low densities in this habitat type. The most common and abundant ant was Plagiolepis alluaudi, which favored the native tree Pipturus albidus. Ecological effects of ants on arthropods were found to be modest, with overall arthropod community composition not significantly different between ant-occupied and ant-free trees. Most taxonomic groups were similar in abundance and richness between ant-occupied and ant-free trees, except adventive Coleoptera, adventive Hemiptera, and Lepidoptera were less abundant on ant-occupied trees, and adventive Coleoptera and adventive Hemiptera also had lower richness on ant-occupied trees. Among Lepidoptera, caterpillars of two endemic groups had significantly lower incidences on trees with higher ant abundances, while other caterpillars did not. Arthropod trophic structure was largely unaffected, except that chewing herbivores comprised a smaller fraction of biomass on ant-occupied trees. While overall ecological effects were weak in comparison to prior results involving other ant species in Hawai'i, some of the impacts suggest that higher densities of these introduced ant species could result in similar interactions with arthropods as those of the better-studied invasive ant species.

“…Thus, if ancestors of Hawaiian lineages occurred in these old areas, the divergence ages of current Hawaiian taxa from continental relatives (which should be more distantly related than those hypothetical mid-Pacific ancestors) should, minimally, fall in that same time frame. However, the old Hawaiian groups just mentioned are estimated to have separated from continental relatives between 10 million years ago and 30 million years ago (Garb and Gillespie 2009;Givnish et al 2009;Russo et al 2013;Haines et al 2014), thus refuting the involvement of Mesozoic or Early Tertiary islands. Heads (2011Heads ( , 2012a) also invoked terranes accreted to or subducted beneath North America, but these areas are substantially older than even those just mentioned, and, thus, are even less plausibly tied to the current Hawaiian biota.…”

Jurassic primates, immobile ducks and other oddities: a reply to Heads’ review of The Monkey’s Voyage

Abstract. In The Monkey's Voyage, I focused on the issue of disjunct distributions, and, in particular, on the burgeoning support from molecular-dating studies for long-distance dispersal over vicariance as the most reasonable explanation for many (but by no means all) distributions broken up by oceans. Michael Heads' assessment of the book is founded on his long-standing belief, following Croizat, that long-distance dispersal is an insignificant process and, therefore, that disjunctions are virtually always attributable to vicariance. In holding to these notions, Heads offered a series of unsound arguments. In particular, to preserve an 'all-vicariance' perspective, he presented a distorted view of the nature of long-distance dispersal, misrepresented current applications of fossil calibrations in molecular-dating studies, ignored methodological biases in such studies that often favour vicariance hypotheses, repeatedly invoked irrelevant geological reconstructions, and, most strikingly, showed a cavalier approach to evolutionary timelines by pushing the origins of many groups back to unreasonably ancient ages. The result was a succession of implausible histories for particular taxa and areas, including the notions that the Hawaiian biota is almost entirely derived from ancient (often Mesozoic) central Pacific metapopulations, that the disjunctions of extremely mobile organisms such as ducks rarely, if ever, result from long-distance dispersal, and that primates were widespread 120 million years before their first appearance in the fossil record. In contrast to Heads' perspective, a central message of The Monkey's Voyage is that explanations for disjunct distributions should be evaluated on the basis of diverse kinds of evidence, without strong a priori assumptions about the relative likelihoods of long-distance dispersal and vicariance.
