Diaphanosoma dubium Manuilova, 1964, is a widespread planktonic water flea in Asian freshwater. Although sharing similar ecological roles with species of Daphnia, studies on D. dubium and its congeners are still few and lacking a genome for the further studies. Here, we assembled a high quality and chromosome level genome of D. dubium by combining...

The center-periphery hypothesis (CPH) predicts that peripheral populations will have lower genetic variation than those at the center of a species' distribution. However, ecological margins do not always coincide with geographical edges when topographies are diverse. Historical climate changes can also strongly affect genetic variation. Here, we ex...

The Northwest Pacific marginal waters comprising the South China Sea, East China Sea, Yellow Sea, and the Sea of Japan have unique geomorphic features. The Japanese flounder Paralichthys olivaceus, which is endemic to the Northwest Pacific, has high nutritional, economic, and ecological value. To allow the examination of the demographic history and...

We examined the evolutionary status of the genus Oliotius Kottelat, 2013, clarified the mitogenome structure of Smiliogastrinae, and analyzed its phylogenetic information to provide a reference for the taxonomy, evolutionary genetics, and germplasm identification of Smiliogastrinae. Using next-generation sequencing, the complete mitogenome sequence...

Daphnia galeata is a common and dominant species in warmer waters, and has a strong top-down effect on both phytoplankton and bacteria. The knowledge of its temporal and spatial patterns of genetic diversity is fundamental in understanding its population dynamics and potential ecological function in ecosystems. Its population genetics have been inv...

Large tropical continental islands could serve as refugia for southward retreating taxa during climatic oscillations. To test this expectation, we investigated the genetic diversity of Diaphanosoma dubium Manujlova (1964) from Hainan Island (> 30,000 km2), one of the largest islands of China, and its adjacent mainland. We collected 37 populations r...

Comparative analysis of the mitogenomes of two Corydoras (Siluriformes, Loricarioidei) with nine known Corydoras, and a phylogenetic analysis of Loricarioidei. ZooKeys Abstract Corydoras is a speciose catfish genus from South America with widely investigated phylogenetic and evolutionary relationships. The complete mitogenomes of C. aeneus and C. p...

In deserts, pond cladocerans suffer harsh conditions like low and erratic rainfall, high evaporation, and highly variable salinity, and they have limited species richness. The limited species can take advantage of ephippia or resting eggs for being dispersed with winds in such habitats. Thus, environmental selection is assumed to play a major role...

Rotifers are the most diverse group in freshwater zooplankton and play an important role in food webs and ecosystems. DNA barcoding has become a useful approach to investigate species diversity at local and regional scales, but its application is still limited by efficient primers for the group. To test a pair of primers 30F/885R recently designed...

Background Diaphanosoma excisum and D. dubium are parapatrically distributed in tropical and subtropical waters, and rarely coexist at local communities in the transition between tropics and subtropics. According to Janzen’s hypothesis and the modern coexistence theory, the specific thermal adaptation and strong interspecific competition between th...

The mitochondrial genome of Phyllodiaptomus diaptomus was sequenced and assembled via Next-Generation Sequencing (NGS) and iterative assembly with a reference seed. The genome is 16446 bp long, A + T biased (69.4%), with 13 protein-coding genes, 22 tRNAs, and 2 rRNA. All protein-coding genes are initiated by a typical “ATN” codon. ND1, ND2, ATP6 ge...

Although the traditional Folmer and Prosser primers enable successful amplification of COI ‘barcoding’ sequences in freshwater zooplankton species, many freshwater zooplankters including Phyllodiaptomus tunguidus are difficult to be amplified using traditional primers. Phyllodiaptomus tunguidus is an endemic calanoid copepod species, widely distrib...

The mitochondrial genome of Atrocalopteryx melli was sequenced and assembled via Next-Generation Sequencing (NGS) and iteratively assembly process with a reference seed. This genome is 15,562 bp long and A + T biased (71%), with 37 genes arranged in common order of Odonata. All protein-coding genes are initiated by typical “ATN” codon, and 9 genes...

Diaphanosoma has been called “tropical Daphnia” for its strong ecological role in tropical freshwater as Daphnia in temperate waters. The present study sequenced and annotated the mitochondrial genome (MG) of Diaphanosoma dubium. The MG of Diaphanosoma dubium is 16,362 bp in length, with typical metazoan gene composition. Phylogenetic analysis conf...

The dormant egg bank in sediments has been regarded as a pool of species diversity and genetic information of freshwater Cladocera. Hatchings from the sediments strongly and directly affect the abundance and genetic structure of active population of Cladocera. In the present study, we sampled the active population in water column and picked up dorm...

Despite the contribution of DNA barcoding towards understanding the biodiversity and distribution of species, the success of the mitochondrial cytochrome c oxidase subunit I gene (COI) amplification has been quite variable when it comes to Cephalopoda. Some species in this class such as Sthenoteuthis oualaniensis seem to be more difficult to amplif...
