Abstract:
... Conventionally, Porcine teschovirus (PTV) consists of 13 genotypes (PTV 1–13, which belong to Teschovirus A); however, several novel members including PTV 14–22 have been discovered recently. PTV 21 was identified as a novel Teschovirus species named Teschovirus B. In this study, almost all 22 reported PTV genotypes except PTV 6, 7, 12 and 20 were identified in the pig populations of western Jiang ...

Abstract:
... A new classification of Myrtaceae tribe Chamelaucieae DC., derived from a molecular phylogenetic analysis based on nr ETS and cp trnK and atpB–rbcL spacer sequences, is presented. Eleven subtribes are recognised, eight of which are new. The currently accepted circumscriptions of subtribes Calytricinae Benth. and ‘Euchamelaucieae Benth.’ (nom. inval.) are retained, with the latter being formally pu ...

Abstract:
... The developments in the study of digeneans of deep-sea fish in the 21st Century are documented and discussed. Most recent work has been on the bathyal fauna (i.e. 1,000m-2,999 m depth), with virtually nothing on the abyssal fauna (i.e. deeper than 3,000 m). The one study on hydrothermal vent digeneans has indicated that these regions probably harbour a distinctive fauna. The demarcation of the dee ...

Abstract:
... For 15 years, the eukaryote Tree of Life (eToL) has been divided into five to eight major groupings, known as ‘supergroups’. However, the tree has been profoundly rearranged during this time. The new eToL results from the widespread application of phylogenomics and numerous discoveries of major lineages of eukaryotes, mostly free-living heterotrophic protists. The evidence that supports the tree h ...

Abstract:
... For the Upper Triassic, conodonts are the primary tools utilized in biostratigraphic investigations. For an effective biostratigraphic zonation, the species should be constrained by clear phylogenetic relationships, in which the stratigraphic ranges and taxonomy are reliable. Unfortunately, a phylogenetic framework for the Late Triassic pectiniform conodonts is almost missing, except for particula ...

Abstract:
... Microbiology has unraveled rich evidence of ongoing reticulate evolutionary processes and complex interactions both within and between cells. These phenomena feature real biological networks, which can logically be analyzed using network-based tools. It is thus not surprising that network sciences, a field independent from evolutionary biology and microbiology, have recently pervasively infused th ...

We define phylosystemics, a multidisciplinary strategy uniting short timescale interaction studies from systems biologists and ecologists with the longer timescale studies familiar to evolutionary biologists, taking advantage of methods from network sciences. Phylosystemics superimposes evolutionary information on entities/edges forming interaction networks produced by systems biology and ecology. ...

Abstract:
... Carpels, the female reproductive organs of flowering plants, are of major economic importance since much of our food is ultimately derived from carpel tissue and they are a defining innovation for flowering plants. Amazingly, little is known about the origin and conservation of the developmental program of the carpel besides the knowledge generated by utilizing Arabidopsis thaliana. However, in th ...

Abstract:
... A variety of relationships have been observed between sexual dimorphism and species diversity, from positive to negative and nonsignificant. Although many hypotheses have been proposed to explain these relationships, it has proven difficult to understand why patterns are so variable. Most studies on this topic have used clades as phylogenetically independent replicates for pattern analysis, but a ...

A clade on Taiwan, represented by Kurixalus idiootocus and the Kurixalus eiffingeri species complex, is deemed to have been resident since the middle Cenozoic; its closest congeners are in southern Indochina (not in the adjacent p ...

Mayflies from the family Leptophlebiidae are cosmopolitan and highly diverse morphologically; they are also the largest family in numbers of genera and the second in number of species in the order Ephemeroptera. In spite of their broad diversity and the efforts employed to understand the evolution of this group, the internal classification of Leptophlebiidae remains controversial at all levels. Mo ...

Abstract:
... To better understand insect evolution, fossils – mainly known by their wings – must be used as terminals in phylogenetic analyses. Such analyses are, however, rarely performed because of a lack of consensus on the homology of venation in insects. Researchers do not agree with the current concept on the exact number and identity of the main veins. Here, we confirm the presence, which has been in qu ...

Abstract:

Recent taxonomic and molecular studies reported cryptic diversity in this group and suggested that the often‐used scale morphology is not a reliable character for species delineation in the genus. Here, we described three freshwater Cochliopodium spp. from the southeastern United State ...

Abstract:
... The metabolic theory of ecology predicts that rates of metabolic processes play a central role in constraining important fitness traits such as home‐range size. Locomotory behaviours are physiologically expensive, yet the relative importance of the animal's energetics in determining their home ranges is unknown. It is tested here whether maintenance costs (BMR; basal metabolic rate), energetic cap ...
