Abstract
Paratya australiensis Kemp (Decapoda: Atyidae) is a widely distributed freshwater shrimp in eastern Australia. The species has been considered as an important stream organism for studying genetics, dispersal, biology, behaviour and evolution in atyids and is a major food source for stream dwelling fishes. Paratya australiensis is a cryptic species complex consisting of nine highly divergent mitochondrial DNA lineages. Previous studies in southeast Queensland showed that “lineage 4” favours upstream sites at higher altitudes, with cooler water temperatures. This study aims to identify putative selection and population structure between high elevation and low elevation populations of this lineage at relatively small spatial scales. Sample localities were selected from three streams: Booloumba Creek, Broken Bridge Creek and Obi Obi Creek in the Conondale Range, southeast Queensland. Six sample localities, consisting of 142 individuals in total were sequenced using double digest Restriction Site Associated DNA-sequencing (ddRAD-seq) technique. Among the 142 individuals, 131 individuals shared 213 loci. Outlier analysis on 213 loci showed that 27 loci were putatively under selection between high elevation and low elevation populations. Outlier analysis on individual streams was also done to test for parallel patterns of adaptation, but there was no evidence of a parallel pattern. Population structure was observed using both the 27 outliers and 186 neutral loci and revealed similar population structure in both cases. Therefore, we cannot differentiate between selection and drift here. The highest genetic differentiation was observed between high elevation and low elevation populations of Booloumba Creek, with small levels of differentiation in the other two streams.

Abstract
The mitochondrial genome sequence of the Australian freshwater shrimp, Paratya australiensis, is presented, which is the fourth for genera of the superfamily Atyoidea and the first atyid from the southern hemisphere. The base composition of the P. australiensis, mitogenome is 33.55% for T, 18.24% for C, 35.16% for A, and 13.06% for G, with an AT bias of 71.58%. It has a mitogenome of 15,990 base pairs comprised of 13 protein-coding, 2 ribosomal subunit and 22 transfer RNAs genes and a non-coding AT-rich region. The mitogenome gene order for the species is typical for atyid shrimps, which conform to the primitive pan crustacean model.

Abstract
Conservation plans can benefit from understanding patterns of genetic structure because many endangered species are spatially fragmented. In particular, headwater species in high elevations are expected to exhibit a high level of population structure, as dispersal through lowland streams may be limited. Euastacus urospinosus is an endangered freshwater crayfish that, until recently, was thought to have a distribution of just 200 km2. In the current study, we identified a total of 26 locations for this species across a 1225 km2 region spanning the Brisbane and Mary River catchments of south-east Queensland, Australia. We then used mitochondrial DNA sequence data to investigate the population structure and the phylogeographic divergence between four uplands. We found significant population differentiation for this species, which conforms to the headwater model of genetic structure. Further, we found that fragmentation between these uplands is most likely historical, as the first divergence between lineages dated back 2.1 million years. Overall, we found no reason to remove the conservation rating of ‘endangered’ for this species. Conservation plans should seek to preserve the genetic integrity of these uplands by considering them to be genetically distinct and isolated populations.

Abstract
Mitochondrial cytochrome oxidase subunit I (COI) gene was utilized to assess the population genetics of the commercially important black scar oyster, Crassostrea iredalei among 11 populations throughout the west and east coasts Peninsular Malaysia and Sabah (Malaysian Borneo). Overall, populations of C. iredalei demonstrated low nucleotide diversity π (0.000-0.004) and low-to-high haplotype diversity h (0.000-0.795) levels. Genetic structuring was detected between the Peninsular Malaysia and Sabah populations as revealed by the FST analysis. However, the COI gene analyses showed minimal and non-significant (p > 0.05) population differentiation within the east and west coasts Peninsular Malaysia and Sabah regions. This was attributed to both high larval dispersal along the east and west coasts and human-driven spat translocation between the two coastlines due to C. iredalei cultivation practices. Phylogeographic relationships inferences were also conducted to further support these hypotheses. The neutrality and mismatch distribution analyses suggested that C. iredalei had experienced a/several bottleneck event(s), followed by population expansion. The molecular information obtained from this study could be incorporated in a pragmatic aquaculture management strategy of wild broodstock and the hatchery lines of C. iredalei in Malaysia.

Abstract
Many aquatic species usually considered to be 'cosmopolitan' have been identified as cryptic species complexes, based on deep genetic differentiation. However, reproductive isolation among sibling cryptic species has rarely been studied, and interspecific hybridization is common in some taxa.We investigated isolation mechanisms and possible introgression among three cyclical parthenogenetic rotifer species in the Epiphanes senta complex that are found in very different freshwater habitats: temperate floodplains, subtropical desert rock pools and a tropical alpine lake. Whereas Epiphanes ukera is reproductively isolated from E. chihuahuaensis and E. hawaiiensis, the latter hybridize under laboratory conditions.While reproductive isolation is incomplete, RAPD profiles indicated unique genetic signatures and showed no evidence for introgression, indicating that these three species are diverging and have independent evolutionary trajectories.Testing cues for sexual reproduction in these cyclic parthenogens demonstrated that mixis in E. chihuahuaensis and E. ukera is influenced by population density, whereas E. hawaiiensis females rarely produce mictic offspring regardless of density. Different mixis cues are likely to separate sexual periods and effectively cause reproductive isolation between the species. Epiphanes ukera and E. chihuahuaensis males display mate guarding behaviour, and E. ukera males distinguish between conspecific and heterospecific females in mate choice experiments. Geographic isolation, along with different cues for mixis induction and mate recognition, act as reproductive barriers among these sibling species.

Abstract
Shrimp of the family Atyidae are important members of nearly all tropical (and most temperate) fresh and brackish water ecosystems in the world. To date, a complete mitochondrial genome from this important crustacean group has not been reported. Here, we present the complete mitochondrial DNA sequence of the Hawaiian atyid Halocaridina rubra [Holthuis, L.B., 1963. On red coloured shrimps (Decapoda, Caridea) from tropical land-locked saltwater pools. Zool. Meded.16, 261-279.] (Crustacea: Decapoda: Atyidae). The genome is a circular molecule of 16,065 bp and encodes the 37 mitochondrial genes (13 protein-coding, 22 tRNAs, and two rRNAs) typically found in the metazoa. Gene order and orientation in the H. rubra mitochondrial genome is syntenic with most malacostracans that have been examined to date. Of special note is the absence of the dihydrouridine (DHU) arm stem from tRNA(Tyr) and the use of CCG as an initiation codon for cytochrome oxidase subunit I (COI); these represent the first reported examples of such phenomena in the Malacostraca. Phylogenetic analyses utilizing complete mitochondrial sequences from other malacostracans place H. rubra as sister to Macrobrachium rosenbergii, which also belongs to the Infraorder Caridea. However, the placement of this infraorder, as well as the Infraorder Dendrobrachiata, in the phylogeny of the Decapoda varied depending on outgroup selection. Data from additional mitochondrial genomes, such as basal decapods like the Stenopodidea, should contribute to a better overall understanding of decapod phylogenetics.

Abstract
Anchialine habitats, landlocked bodies of mixohaline water that fluctuate with the tides but have no surface connection to the sea, are known from around the world. Many anchialine organisms have widespread distributions and it has been hypothesized that high levels of gene flow and low levels of genetic differentiation are characteristic of populations from these habitats. However, the generality of this hypothesis requires further assessment, particularly in light of the significant negative impact these habitats and their biota have experienced from anthropogenic causes. This study investigated the population structure and demography of an endemic Hawaiian anchialine species, the atyid shrimp Halocaridina rubra, using mitochondrial cytochrome c oxidase subunit I (COI) gene sequences. A survey of 305 individuals from 16 populations collected on the island of Hawaii revealed 135 haplotypes. These haplotypes belonged to one of two divergent (2.7-4.9%) lineages; notably, no haplotypes were shared between the two coasts of the island. Along each coast, strong subdivision and little to no gene flow occurs between populations separated by > 30 km. The population structure and demography of H. rubra on Hawaii are influenced by regional hydrology, geology, volcanism and two distinct colonization events of the island. Thus, H. rubra on Hawaii demonstrates that populations of endemic anchialine organisms may exhibit significant levels of genetic structure and restricted levels of gene flow over limited geographic scales. This report brings novel insight into the biology of anchialine organisms and has important implications for the future management of these habitats and their biota.

Abstract
The widespread distribution of the freshwater shrimp Paratya australiensis in eastern Australia suggests that populations of this species have been connected in the past. Amphidromy is ancestral in these shrimps, although many extant populations are known to be restricted to freshwater habitats. In this study, we used a fragment of the cytochrome c oxidase I mitochondrial DNA (mtDNA) gene to examine diversity within P. australiensis and to assess the relative importance of amphidromy in its evolutionary history. We hypothesized that if transitions from an amphidromous to a freshwater life history were important, then we would find a number of divergent lineages restricted to single or groups of nearby drainages. Alternatively, if amphidromy was maintained within the species historically, we expected to find lineages distributed over many drainages. We assumed that the only way for divergence to occur within amphidromous lineages was if dispersal was limited to between nearby estuaries, which, during arid periods in the earth's history, became isolated from one another. We found nine highly divergent mtDNA lineages, estimated to have diverged from one another in the late Miocene/early Pliocene, when the climate was more arid than at present. Despite this, the geographic distribution of lineages and haplotypes within lineages did not support the notion of a stepping-stone model of dispersal between estuaries. We conclude that the extensive divergence has most likely arisen through a number of independent amphidromy-freshwater life history transitions, rather than via historical isolation of amphidromy populations. We also found evidence for extensive movement between coastal and inland drainages, supporting the notion that secondary contact between lineages may have occurred as a result of drainage rearrangements. Finally, our data indicate that P. australiensis is likely a complex of cryptic species, some of which are widely distributed, and others geographically restricted.

Abstract
We measured spatial genetic structure within three previously described mitochondrial lineages of the atyid shrimp, Paratya australiensis, occurring in upland streams of two major catchments within the Sydney Water Supply Catchment, New South Wales, Australia. In all three lineages, there was significant spatial structuring of genetic variation between catchments. In two lineages, recurrent but restricted maternal gene flow has apparently predominated in shaping within-catchment genetic structure, although this framework may be overlaid with episodic contiguous/long-distance expansion events. In the third lineage, there was no evidence of spatial genetic structuring within one of the catchments, because one haplotype was both common and widespread throughout the sampled area. High-frequency haplotypes were also shared among subcatchments in the other two lineages, and we discuss both historical and contemporary processes that may have left these genetic signatures. Our results are generally concordant with previous reports of significant population structuring in P. australiensis, occurring in upland river reaches elsewhere in eastern Australia. We propose that restricted dispersal and gene flow among upland populations of P. australiensis is linked to dramatic architectural structuring within and among mountain streams.
