“…While younger than previous estimates*e.g. moa divergences (from other paleognaths) were interpreted to be 82 Ma by Cooper et al (2001) and inferred as 78.9914 Ma by Haddrath & Baker (2001)* this age is still feasible for vicariance since Zealandia separated from East Antarctica over the period 82Á55 Ma (Gaina et al 1998;Schellart et al 2006; see Allentoft & Rawlence 2011).…”

“…During the Eocene, the continental crust in the New Caledonia area was tectonically active, being in collision with the Loyalty Islands arc, and obduction at this time placed a layer of oceanic crust (lithosphere) over the submerged continental crust. New Caledonia emerged during an Oligocene lithosphere extension phase, uplifting with a cover of lithospheric ultramafic rocks (Paris 1981a,b;Aitchison et al 1995;Cluzel et al 2001;Crawford et al 2003;Pelletier 2006;Schellart et al 2006). The presentday mountains are relatively old since they are the product of complex orogenesis from Oligocene time, as indicated by several series of lateritic beds ranging from sea level to mountain tops (Chevillotte et al 2006).…”

New Caledonia has generally been considered a continental island, the biota of which largely dates back to Gondwanan times owing to its geological origin and the presence of phylogenetic relicts. This view is contradicted by geological evidence indicating long Palaeocene and Eocene submersions and by recent biogeographic and phylogenetic studies, with molecular or geophysical dating placing the biota no older than the Oligocene. Phylogenetic relicts do not provide conclusive information in this respect, as their presence cannot be explained by simple hypotheses but requires assumption of many ad hoc extinction events. The implication of this new scenario is that all the New Caledonian biota colonized the island since 37 Ma Local richness can be explained by local radiation and adaptation after colonization but also by many dispersal events, often repeated within the same groups of organisms. Local microendemism is another remarkable feature of the biota. It seems to be related to recent speciation mediated by climate, orography, soil type and perhaps unbalanced biotic interactions created by colonization disharmonies. New Caledonia must be considered as a very old Darwinian island, a concept that offers many more fascinating opportunities of study.

“…Fossilcalibrated, molecular-clock reconstructions indicate that Euastacus and its sister genus Astacopsis diverged in the Cretaceous, approximately 116 Ma [22]. Since then, Australia has experienced major environmental change associated with the break-up of Gondwana (which began around 165 Ma) [22,27]. From approximately 90 Ma, uplift of the great dividing range (GDR) [28] established the main river basins seen today (figure 1) [29].…”

Australian spiny mountain crayfish and their temnocephalan ectosymbionts: an ancient association on the edge of coextinction?

et al. 2016

Australian spiny mountain crayfish (Euastacus, Parastacidae) and their ecotosymbiotic temnocephalan flatworms (Temnocephalida, Platyhelminthes) may have co-occurred and interacted through deep time, during a period of major environmental change. Therefore, reconstructing the history of their association is of evolutionary, ecological, and conservation significance. Here, time-calibrated Bayesian phylogenies of Euastacus species and their temnocephalans (Temnohaswellia and Temnosewellia) indicate nearsynchronous diversifications from the Cretaceous. Statistically significant cophylogeny correlations between associated clades suggest linked evolutionary histories. However, there is a stronger signal of codivergence and greater host specificity in Temnosewellia, which co-occurs with Euastacus across its range. Phylogeography and analyses of evolutionary distinctiveness (ED) suggest that regional differences in the impact of climate warming and drying had major effects both on crayfish and associated temnocephalans. In particular, Euastacus and Temnosewellia show strong latitudinal gradients in ED and, conversely, in geographical range size, with the most distinctive, northern lineages facing the greatest risk of extinction. Therefore, environmental change has, in some cases, strengthened ecological and evolutionary associations, leaving host-specific temnocephalans vulnerable to coextinction with endangered hosts. Consequently, the extinction of all Euastacus species currently endangered (75%) predicts coextinction of approximately 60% of the studied temnocephalans, with greatest loss of the most evolutionarily distinctive lineages.
