Abstract
The Chinese pomfret Pampus chinensis is one of the most economic and ecological important marine fish species in China. In the present study, the population genetic structure and genetic diversity of P. chinensis were evaluated from a total sample size of 180 individuals representing six populations from the East China Sea and the South China Sea using mitochondrial cytochrome c oxidase subunit I (COI) gene. A total of 24 variable sites (including 3 singleton sites and 21 parsimony information sites) were observed, and 18 haplotypes were defined. The haplotype diversity (Hd) of the populations ranged from 0.559 to 0.775, and the nucleotide diversity (π) ranged from 0.330 to 1.090%. Analysis of molecular variance (AMOVA) reveals that the main variation (66.02%) was among individuals within populations. The average pairwise differences and ϕST values indicated significant genetic differentiation between Dongxing population and the other populations. The results of the present study are helpful for the sustainable management and utilization of this species.

Abstract
The objective of this study is to describe the genetic population structure and demographic history of the endangered marine fish, Epinephelus marginatus, within Malta's Fisheries Management Zone for the purpose of localised conservation planning. Epinephelus marginatus is a long-lived, sedentary, reef-associated protogynous hermaphrodite with high commercial and recreational value that is at risk of extinction throughout its global distribution. Based on global trends, population substructuring and gaps in local knowledge this has led to an increased interest in evaluation of local stock. Assessment of Maltese demography was based on historical and contemporary catch landings data whilst genetic population structure and regional connectivity patterns were evaluated by examining 175 individuals collected within the central Mediterranean region between 2002 and 2009 using 14 nuclear microsatellite loci. Demographic stock assessment of Maltese E. marginatus' revealed a 99% decline in catch landings between 1947 and 2009 within the Fisheries Management Zone. A contemporary modest mean size was observed, 3 ± 3 kg, where approximately 17% of the population was juvenile, 68% female/sex-changing and 15% were male with a male-to-female sex ratio of 1:5. Genetic analysis describes the overall population of E. marginatus' within the Fisheries Management Zone as decreasing in size (ƟH = 2.2), which has gone through a significant size reduction in the past (M = 0.41) and consequently shows signs of moderate inbreeding (FIS = 0.10, p < 0.001) with an estimated effective population size of 130 individuals. Results of spatially explicit Bayesian genetic cluster analysis detected two geographically distinct subpopulations within Malta's Fisheries Management Zone and that they are connected to a larger network of E. marginatus' within the Sicily Channel. Results suggest conservation management should be designed to reflect E. marginatus' within Malta's Fisheries Management Zone as two management units.

Abstract
This present study investigated micro- and macro-geographic microsatellite DNA variations using five polymorphic microsatellite loci from 27 brown trout populations in Turkey. Average number of alleles and average observed heterozygosity were 7.4 and 0.254, respectively. Even populations from the same sea basin and river system (the so called micro-geographic regions) had unique alleles. Genetic variation among the populations from macro-geographic regions (different sea basins and river systems) was 45.78%. The mtDNA lineages of brown trout that have previously been identified by mtDNA analyses were supported by the analysis of the microsatellite DNA data in general. The Çatak population, which belongs to the Tigris lineage, was clustered together with the Euphrates populations within the Adriatic mtDNA lineage, based on microsatellite data. Both mitochondrial and microsatellite DNA analyses have made it possible to determine a secondary contact between Adriatic and Tigris lineages.

Abstract
Mitochondrial DNA cytochrome b sequences (1140 bp) in 61 specimens of Chinese spiny loach Cobitis sinensis from 12 drainages in Taiwan were identified as two major clades, exhibiting a southern and a northern distribution, north of TzengWen and south of TzengWen (including TzengWen), respectively. The divergence time between these two phylogroups was estimated at 7.34-9.06 million years before present (B.P.), but these two phylogroups were formed c. 3.41-4.23 and 2.22-2.75 M B.P., respectively. Moreover, geological events have been recalculated that Taiwan Island emerged above sea level at an estimate of c. 4-5 M B.P., and quickly became its present shape at c. 2 M B.P. through mountain building. These results suggest that these two major clades of C. sinensis in Taiwan might originate from two different continental populations, since the island's initial isolation in the Pliocene. Within southern Taiwan, the initial colonization was hypothesized to be in KaoPing River, followed by its northward dispersal. The high divergence between KaoPing and TzengWen was influenced by glaciations and landforms. Within north Taiwan, the colonization was from the Miaoli Plateau through western Taiwan to north-eastern and northern Taiwan. This dispersal pattern is concordant with the previously proposed hypothesis. Apparently, both geological and phylogeographic evidence suggested that river capture of the upper Takia River by the LanYang River promoted range expansion in freshwater fishes and also indicated that the Central Range within Taiwan did not act as a barrier to the dispersal of C. sinensis.

Abstract
We explore the historical demography of the Adriatic lineage of brown trout and more explicitly the colonization and phylogenetic placement of Ohrid trout, based on variation at 12 microsatellite loci and the mtDNA control region. All Adriatic basin haplotypes reside in derived positions in a network that represents the entire lineage. The central presumably most ancestral haplotype in this network is restricted to the Iberian Peninsula, where it is very common, supporting a Western Mediterranean origin for the lineage. The expansion statistic R2, Bayesian based estimates of demographic parameters, and star-like genealogies support expansions on several geographic scales, whereas application of pairwise mismatch analysis was somewhat ambiguous. The estimated time since expansion (155,000 years ago) for the Adriatic lineage was supported by a narrow confidence interval compared to previous studies. Based on microsatellite and mtDNA sequence variation, the endemic Ohrid trout represents a monophyletic lineage isolated from other Adriatic basin populations, but nonetheless most likely evolving from within the Adriatic lineage of brown trout. Our results do not support the existence of population structuring within Lake Ohrid, even though samples included two putative intra-lacustrine forms. In the interests of protecting the unique biodiversity of this ancient ecosystem, we recommend retaining the taxonomic epithet Salmo letnica for the endemic Ohrid trout.

Abstract
The present study aims at a phylogeographic description of Zacco platypus from southeast China, in order to detect subdivisions within the nominal species. Two main basins were sampled: the Chang Jiang (Yangstze River) in central and east China (Hunan and Sichuan provinces) and the Xi Jiang, the more southern main tributary of the Zhu Jiang (Pearl River, Guangxi province). A total of 27 intron systems were tested, five of them were informative and gave 12 interpretable and polymorphic loci. Within the diversity of Z. platypus, four genetic groups were identified by multidimensional (FCA) analyses, corresponding to distinct genetic pools. The geographical distribution of the genetic groups corresponds neither with the drainage structure, nor the geographic distances between samples. It follows that isolation by distance and limited migration are insufficient to explain this geographic structure. The history of the river network therefore appears to have played an important role.

Abstract
Genetic variation in nine wild brown trout (Salmo trutta L.) populations was studied by means of allozyme and microsatellite markers. All brown trout populations were clearly separated into two clusters that represented the Sil and Duero basins. Although both markers revealed a strong genetic differentiation between basins, microsatellite loci resulted much more accurate when population structure at the intrabasin level was analysed. Also pairwise multilocus FST estimates and assignment tests of individual fish to the set of sampled populations demonstrated a much higher efficiency of microsatellites compared to allozymes. The analysis of both markers provides new insights in defining the conservation units at this local area and confirms the existence of a recognized sub-lineage in the Duero basin. The management implications of these findings are discussed and changes in trout release activity are recommended to avoid mixing of trout gene pools mainly in the Sil basin.

Abstract
The phylogeographical patterns and population genetic structures of Varicorhinus barbatulus in Taiwan were investigated based on genetic diversity of 34 allozyme loci and nucleotide sequences of 3' end of the cytochrome b gene, tRNA genes, D-loop control region, and the 5' end of the 12S rRNA of mtDNA. Allozyme and mtDNA analyses revealing evident geographical structuring suggest limited gene flow between populations (F(ST)=0.511 and 0.791, respectively). Low genetic variability within populations (P=5.56%; He=0.018) based on allozymes and significantly negative Tajima's D statistics based on mtDNA suggest that most populations in Taiwan may have originated from a small number of founders followed by demographic expansion. The gene genealogy of mtDNA identified six lineages corresponding to major drainages that were separated by the geological barriers due to vicariant events. A minimum spanning network based on nucleotide substitutions reflects divergence from populations of the Miao-li Plateau to northern and southern regions of the island. In contrast to a previous hypothesis that suggests an early invasion to eastern part of Taiwan prior to the lifting of central mountain range some one million years ago, the mtDNA genealogy and molecular dating reveal very recent colonization of the eastern population. Nested clade analyses revealing significant associations between genetic structure and geographical division identify past fragmentation and range expansion as major phylogeographical events that shaped the geographical distribution of this species in Taiwan.

Abstract
Microsatellite markers have been used to study the genetic variability of rainbow wrasse (Coris julis) Mediterranean and Atlantic populations. Differentiation tests failed to reveal any significant genetic differentiation among samples from continental Portugal and the Azores, despite more than 1800 km of geographical separation. Preliminary results tended to indicate a significant genetic differentiation among Atlantic and Mediterranean samples. It also supported the specific status of Cape Verde populations (Coris atlantica). We compare these results with previous mtDNA analyses and propose a biogeographic scenario that could explain our results.
