  1. Phylogeny of Indo-West Pacific pontoniine shrimps (Crustacea: Decapoda: Caridea) based on multilocus analysis

    The phylogenetic relationships of the subfamily Pontoniinae was discussed based on mitochondrial and nuclear DNA. Among the 20 genera with more than one species included in the analysis, monophyly was evident with strong nodal support for 16. The genera Periclimenaeus and Dactylonia were shown to be paraphyletic. The results suggest that pontoniines sharing the same hosts may have different evolutionary origins resulting from parallel intrusions of their hosts by morphologically plastic ancestral groups.

  2. The complete mitogenomes of lobsters and crayfish (Crustacea: Decapoda: Astacidea) reveal surprising differences in closely related taxa and convergences to Priapulida

    Compared with the decapod ground pattern, a huge inversion, involving more than half of the mitogenome, has been found in four cambarid freshwater crayfish species and convergently in the lobster Homarus gammarus. Surprisingly, this inversion can also be observed in the distantly related Priapulida (penis worms) belonging to the Cycloneuralia. This multiple convergent evolution within Ecdysozoa suggests a relative ease in the evolution of great similarities in mitochondrial gene order. Hence, mitochondrial gene order data have to be treated with care if used for phylogenetic inferences.

  3. Insights into the evolutionary history of Cervus (Cervidae, tribe Cervini) based on Bayesian analysis of mitochondrial marker sequences, with first indications for a new species

    We applied a coalescent Bayesian approach to most Cervus taxa, including some poorly studied central-Asian populations, using mitochondrial cytochrome b and control region sequences. Red deer (C. elaphus), wapiti (C. canadensis) and sika deer (C. nippon) are confirmed as different species. Tarim populations from central Asia, hitherto subspecies of C. elaphus (C. e. bactrianus, C. e. yarkandensis, C. e. hanglu), revealed worthy of being raised to the species level (C. hanglu). Based on phylogeny and divergence times, a novel evolutionary pattern for Cervus is proposed.

  4. Phylogenetic systematics of leaffishes (Teleostei: Polycentridae, Nandidae)

    Despite being oft-cited examples of ‘evolution in action’, leaffishes are a poorly known group in terms of their relationships. Using both morphological and molecular data – and including for the first time in a molecular genetic study the rare Afronandus from West Africa (pictured) – we generate here a well-supported phylogeny of leaffishes. We confirm that the ‘traditional’ leaffishes do not form a natural group. Rather, they comprise two unrelated families (Polycentridae, Nandidae), with their apparent similarity likely explained by ecological convergence.
