The Status

The status of the genera of the lichen-forming fungal family Megalosporaceae is re-examined. DNA-sequence data utilising three loci and anatomical observations pertaining to the hymenium, asci and ascospores support Megaloblastenia as a distinct genus. Austroblastenia is not supported by molecular, morphological or anatomical data, which suggest that it should be subsumed within Megalospora. Consequently, the new combinations, Megalospora pauciseptata (Shirley) Kantvilas & Lumbsch and M. pupa (Sipman) Kantvilas & Lumbsch, are proposed.

Phylogenetic Placement

AbstractThe phylogenetic placement of the genus Maronina was studied, based chiefly on phenotypic characters such as thallus colour and anatomy, secondary chemistry, the anatomy of the excipulum and the ascus-type. DNA sequence data of mitochondrial and nuclear ribosomal loci from some of the species support the hypothesis that Maronina is nested within Protoparmelia. Hence, Maronina is reduced to synonymy with Protoparmelia. Comparison of genetic distances suggests that the two varieties within M. orientalis should be regarded as distinct species. Consequently, the new combinations Protoparmelia australiensis (Hafellner & R. W. Rogers) Kantvilas et al., P. corallifera (Kantvilas & Papong) Kantvilas et al., P. hesperia (Kantvilas & Elix) Kantvilas et al., P. multifera (Nyl.) Kantvilas et al., and P. orientalis (Kantvilas & Papong) Kantvilas et al. are proposed.

Anatomical Characters

Relationships between Callitris, Actinostrobus and Neocallitropsis, members of the southern hemisphere ‘callitroid clade’ (Callitroideae sensu Gadek et al. 2000) of Cupressaceae, are estimated using a database of 42 morphological and anatomical characters. Callitris is paraphyletic, with Actinostrobus being closer to a large well supported clade of 15 Australian species of Callitris than are C. baileyi, C. macleayana and the New Caledonian taxa. The New Caledonian unispecific endemic, Neocallitropsis, is sister to the clade comprising all Callitris and Actinostrobus species. There are marked differences between this estimate of the phylogeny and two recent estimates based on nuclear encoded DNA sequence data and non-molecular data, respectively, but some simlarities to the molecular estimate are highlighted and lead us here to formally include Actinostrobus within Callitris. Further molecular data are needed to test these results and explore the cause of the conflict between these estimates of the phylogeny within the group, and the status of Neocallitropsis.

The Status

Chorebus cyparissa (Nixon) is added to the British list based on a specimen caught in a Malaise trap in Norfolk, England in 1983. It is also recorded from Bulgaria and, based on DNA sequence data, from Belarus & Turkey. Chorebus navicularis (Nees) is deleted from the British list; its inclusion was probably due to a misidentification and the status of the species itself is uncertain.

The 19Th Century

Expeditions to unexplored or little explored places are important for discovering new species and also for collecting new samples (including specimens and tissues for DNA sequencing ) that may help resolve a plethora of taxonomic problems. In the 19th century, several naturalists explored a number of localities in Amazonia, describing species for which type material was deposited, mostly, in European museums of natural history. Some of these types were lost or destroyed in World War II and recent expeditions have focused on sampling new material from the type localities. material from Boana cinerascens, which allowed us to infer phylogenetic relationships of the Boana punctata group (i.e., green Boana), based on DNA sequence data, and to revaluate the status of B. cinerascens and its synonyms. We designate, redescribe and illustrate a neotype for B. cinerascens, which was described by Spix in 1824, from the Municipality of Tefé, State of Amazonas, Brazil. We revalidate, redescribe, and illustrate Hyla granosa gracilis Melin, 1941(= Boana gracilis). Corroborating previous studies, the green Boana were not recovered as a monophyletic group. Boana cinerascens is sister of B. gracilis plus a clade containing B. atlantica + B. punctata (both species not recovered as monophyletic).

Cheilanthoid Ferns

Morphology-based delimitation of genera in the Cheilanthoid ferns has proved to be problematic and understanding of the phylogeny and relationships amongst Cheilanthoid ferns based on morphological characters has posed even further difficulties, owing perhaps in large part to adaptation by many taxa to xeric habitats, as well as convergent evolution. It is only now with the application of DNA sequence data that relationships of species and genera are becoming clear. Here, we present results of cpDNA sequence data from species that have been traditionally placed in the genus Doryopteris and, based on both these results, and morphological and distribution data, this study helps clarify the concept of the genus Doryopteris its position within the Cheilanthoid ferns and the status of Lytoneuron. As a result, three genera are redefined: Doryopteris, Lytoneuron and Ormopteris.

Alternative Means

Abstract Objective Visualisation methods, primarily color-coded representation of sequence data, have been a predominant means of representation of DNA data. Algorithmic conversion of DNA sequence data to sound—sonification—represents an alternative means of representation that uses a different range of human sensory perception. We propose that sonification has value for public engagement with DNA sequence information because it has potential to be entertaining as well as informative. We conduct preliminary work to explore the potential of DNA sequence sonification in public engagement with bioinformatics. We apply a simple sonification technique for DNA, in which each DNA base is represented by a specific note. Additionally, a beat may be added to indicate codon boundaries or for musical effect. We report a brief analysis from public engagement events we conducted that featured this method of sonification. Results We report on use of DNA sequence sonification at two public events. Sonification has potential in public engagement with bioinformatics, both as a means of data representation and as a means to attract audience to a drop-in stand. We also discuss further directions for research on integration of sonification into bioinformatics public engagement and education.

Lines Of Evidence

Liopeltis is a genus of poorly known, infrequently sampled species of colubrid snakes in tropical Asia. We collected a specimen of Liopeltis from Pulau Tioman, Peninsular Malaysia, that superficially resembled L. philippina, a rare species that is endemic to the Palawan Pleistocene Aggregate Island Complex, western Philippines. We analyzed morphological and mitochondrial DNA sequence data from the Pulau Tioman specimen and found distinct differences to L. philippina and all other congeners. On the basis of these corroborated lines of evidence, the Pulau Tioman specimen is described as a new species, L. tiomanica sp. nov. The new species occurs in sympatry with L. tricolor on Pulau Tioman, and our description of L. tiomanica sp. nov. brings the number of endemic amphibians and reptiles on Pulau Tioman to 12.
