According to the results of the phylogeny, it is possible to observe the formation of heterogeneous groups of individuals from different mangrove islands, asserting that genetic differences between individuals from each island are not explained by geographic distance.

The same program was used to estimate the Fs statistic 13 and the distribution between pairs of frequencies Mismatch distribution was evaluated. Multimodal distributions also represent a reduction in the effective size of the population, which leads to a multimodal mismatch, or that populations are in demographic equilibrium after passing through a bottleneck.

Zool J Linn Soc-Lond ; 3: Differences due to size are not sufficient to determine the existence of different populations, mainly because these differences may happen due to differences in fishery patterns increasing the ratio of smaller sizes. On the other hand, the analysis of the distribution between pairs of sequences Mismatch distribution performed in the five islands under study as a whole, showed a anadzra distribution as tubercuposa in Figure 1.

En el caso de A.

Use of different geometric morphometrics tools for the discrimination of phenotypic stocks of the striped clam Ameghinomya antiqua Veneridae in north Patagonia, Argentina. Bivalvia in the mangrove ecosystem of the Southern coast of Ecuador.

Degrees of freedom D. The studied populations are not tubefculosa and although there is a decrease of natural banks, the genetic diversity is high. Later, the parameters of genetic diversity haplotypical and nucleotidical were measured, and the analysis anarara distribution between frequency pairs Mistmach distribution was elaborated.


The analysis of nucleotide variation showed percentages of base composition equal to Ministerio de Agricultura y Desarrollo Rural. Historical perspective, lessons, and challenges. For the populations evaluated, the haplotype diversity was 0.

aanadara When the analysis was done separately for each island, a unimodal distribution for La Tiburonera and a multimodal distribution for the other islands was observed San Jorge, El Pajal, La Playa and Bajito Vaqueria Figure 2.

Genetic structure of Korean populations of the clam Ruditapes philippinarum inferred from microsatellite marker analysis. Finally, Figure 3 shows the phylogenetic tree tubercuoosa the resulting groups among individuals from the five islands. We analyzed bases, where monomorphic sites and 99 polymorphic sites were found, of which 81 were parsimonious sites that provided information to define the haplotypes found.

The results obtained in this study, using the COI gene as genetic marker, are the first reports on the genetic diversity for A. Zhaxybayeva O, Gogarten P. The tuberculosx were placed in absolute alcohol previously arranged in individual 1.

Cladogenesis, coalescence and the evolution of the three domains of life. Contrarily, centroide size showed significant variation in organism collected in different zones. Paleontological statistic software package for education and data analysis. These diversity results indicate a possible population expansion 16 ; however, more advanced studies are needed to specify this aspect such as metagenomics, epigenomics, proteomics, metabolomics Currently there are tools to evaluate genetic tubberculosa, which include molecular markers that are a set of techniques that allow visualizing or indicating the presence of allelic variants, as a result of some type of mutation through evolutionary time 7.

On the other hand, the analysis by populations pairs showed no differences between pairs of islands: Estimation of Anadara tuberculosa genetic diversity in five mangroves from Tumaco, using Cytochrome oxidase I enzyme. The results obtained from this study generate new knowledge and will serve as comparison parameters for future works aimed at the conservation of A.

The solid line blue represents the expected distribution in the case of individuals collected from different islands belong to a stationary population. Gene flow and demographic history of the mangrove crab Neosarmatium meinerti: La Playa y BV: Tal como se puede visualizar en el mapa factorial tanto para A.

Agradecemos especialmente al proyecto “Potencial productivo de las poblaciones naturales de la piangua Anadara tuberculosa y A. Multilocus sequence evaluation for differentiating species of the trematode Family Gastrothylacidae, with a note on the utility of mitochondrial COI motifs in species identification.

Elsevier Academic Press, Amsterdam. The genetic diversity observed is the result of the action of the forces of mutation and natural selection, derived from the response of individuals to natural and anthropological environmental changes.

Los pueblos del mar. The amplified and quantified products of PCR were sequenced on both sides Macrogen.

The analysis for each population shows only a unimodal distribution for La Tiburonera, and for the other populations San Jorge, El Pajal, La Playa tuberculoosa Bajito Vaqueria the distribution is multimodal, suggesting that these populations are unequal and stationary.
