The gecko Diplodactylus savagei is restricted to the rocky Pilbara and Ashburton regions of Western Australia. Recent collections have enabled a reappraisal of morphological and genetic diversity within the taxon. Analysis of 1200 base pairs of the mtDNA gene ND2 and surrounding tRNA found strong support for three lineages within D. savagei: an eastern clade (which includes the type location of...

The sigma virus of Drosophila melanogaster (DMelSV) was discovered accidentally over 70 years ago owing to it causing infected flies to become paralysed and die on exposure to CO2. Recently, five other species of Drosophila and a species of Muscidae fly have also been found to be infected with sigma viruses, and together these viruses form a major clade of rhabdoviruses that is a sister clade t...

Bat flies are a diverse clade of obligate ectoparasites on bats. Like most blood-feeding insects, they harbor endosymbiotic prokaryotes, but the origins and nature of these symbioses are still poorly understood. To expand the knowledge of bacterial associates in bat flies, the diversity and evolution of the dominant endosymbionts in six of eight nominal subfamilies of bat flies (Streblidae and ...

Dendrolimus kikuchii Matsumura, 1927 is a serious forest pest causing great damage to coniferous trees in China. Despite its economic importance, the population genetics of this pest are poorly known. We used three mitochondrial genes (COI, COII and Cytb) to investigate the genetic diversity and genetic differentiation of 15 populations collected from the main distribution regions of D. kikuchi...

In this study, the complete mitochondrial genome sequence of the Liuyang black goat was investigated, and phylogenetic relationships between the Liuyang black goat and other species of Caprinae were analyzed. The total length of the mitochondrial genome was 16,715 bp, which consisted of 33.50% A, 27.27% T, 25.98% C, and 13.25% G. The mitochondrial genome contained a major non-coding control reg...

traditionally, capoeta populations from the southern caspian sea basin have been considered as capoeta capoeta gracilis. study on the phylogenetic relationship of capoeta species using mitochondrial cytochrome b gene sequences show that capoeta population from the southern caspian sea basin is distinct species and receive well support (posterior probability of 100%). based on the tree topologie...

The relation between corals and their algal endosymbionts has been a key to the success of scleractinian (stony) corals as modern reef-builders, but little is known about early stages in the establishment of the symbiosis. Here, we show that initial uptake of zooxanthellae by juvenile corals during natural infection is nonspecific (a potentially adaptive trait); the association is flexible and ...

Enterovirus 68 (EVD68) causes respiratory illness, mostly in children. Despite a reported low-level of transmission, the occurrence of several recent outbreaks worldwide including the 2014 outbreak in North America has raised concerns regarding the pathogenesis and evolution of EVD68. To elucidate the phylogenetic features of EVD68 and possible causes for the 2014 outbreak, 216 EVD68 strain seq...

Leishmaniasis is a debilitating infectious disease that has a variety of clinical forms. In China, visceral leishmaniasis (VL) is the most common symptom, and L. donovani and/or L. infantum are the likely pathogens. In this study, multilocus sequence typing (MLST) of five enzyme-coding genes (fh, g6pdh, icd, mpi, pgd) and two conserved genes (hsp70, lack) was used to investigate the phylogeneti...

Circumscriptions of and relationships among many genera and suprageneric taxa of the diverse grass tribe Poeae remain controversial. In an attempt to clarify these, we conducted phylogenetic analyses of >2400 new DNA sequences from two nuclear ribosomal regions (ITS, including internal transcribed spacers 1 and 2 and the 5.8S gene, and the 3'-end of the external transcribed spacer (ETS)) and fi...
