Microsatellite genotype data from seven loci for a phylogeographic/population genetic study of the South African endemic freshwater crab Potamonautes lividus sampled from eight localities in the KwaZulu-Natal and Eastern Cape provinces in South Africa
<ol> <li>During the present study, the phylogeography of the only southern African IUCN Red Listed vulnerable (VU) freshwater crab, <i>Potamonautes lividus</i> was investigated by surveying several localities in the Eastern Cape and KwaZulu-Natal provinces in South Africa. Both nuclear and mitochondrial DNA markers were used, and it was hypothesized, that marked genetic differentiation should be present, while niche modeling was undertaken to explore the distribution of the species along the east coast of South Africa. <span><span>Further, the shortfalls in the present approach to IUCN Red Listing, as illustrated by a vulnerable species of crabs are discussed</span></span>.</li> <li>Results from the mtDNA revealed the presence of two haploclades confined to specimens from the two provinces respectively and the general absence of maternal dispersal; a fact that was further validated by the marked <i>F</i><sub>ST</sub> data and high F<sub>ST</sub>. Within the Eastern Cape haploclade, low frequency maternal dispersal occurred, corroborated by the low F<sub>ST</sub>. In contrast, no haplotypes were shared in the KwaZulu-Natal haploclade a fact corroborated by marked F<sub>ST</sub> differences. </li> <li>The microsatellite data demonstrated the presence of higher frequency, possibly paternally biased dispersal of specimens between the Eastern Cape and KwaZulu-Natal provinces. Our results suggest that presence of two distinct management units within <i>P. lividus</i>. Divergence time estimation suggest a late Pleistocene cladogenesis between the Eastern Cape and KwaZulu-Natal haploclades. </li> <li>Considering the presence of <i>P. lividus</i> in several newly collected nature conservation areas in both provinces, and its potential presence in the intermediary area based on the MAXENT niche modeling, our data suggest the species IUCN Red Listing status should be downgraded to LC.</li> <li>A comparison of all the EN, VU and CR IUCN Red Listed freshwater crabs for the entire Afrotropical region reveals the lack of recent sampling in the three biodiversity hotspots in West, Central and East Africa, with mountainous areas containing a disproportionate number of species with most species being devoid of phylogeographic study. </li> </ol>
Data from: Isolation and characterization of 145 polymorphic microsatellite loci for the common frog (Rana temporaria)
We describe primers and polymerase chain reaction conditions to amplify 145 di-, tri- and tetranucleotide microsatellite loci from the common frog (Rana temporaria), a species commonly used as a model in ecological and evolutionary research. Primers were tested on 46 individuals from two Fennoscandian populations and yielded an average of six to nine alleles per locus (range = 1–30) depending on the population. Average observed heterozygosities in the two populations were 0.16 (range = 0–0.91) and 0.36 (range = 0–1).
Data from: Characterization of 42 polymorphic microsatellite loci in Mimulus ringens (Phrymaceae) using Illumina sequencing
Premise of the study: Microsatellite markers were isolated and characterized in Mimulus ringens (Phrymaceae), a herbaceous wetland perennial, to facilitate studies of mating patterns and population genetic structure. Methods and Results: A total of 42 polymorphic loci were identified from a sample of 24 individuals from a single popula- tion in Ohio, USA. The number of alleles per locus ranged from two to nine, and median observed heterozygosity was 0.435. Conclusions: This large number of polymorphic loci will enable researchers to quantify male fitness, patterns of multiple pa- ternity, selfing, and biparental inbreeding in large natural populations of this species. These markers will also permit detailed study of fine-scale patterns of genetic structure.
Data from: 'True' null allele detection in microsatellite loci: a comparison of methods, assessment of difficulties, and survey of possible improvements
Null alleles are alleles that for various reasons fail to amplify in a PCR assay. The presence of null alleles in microsatellite data is known to bias the genetic parameter estimates. Thus, efficient detection of null alleles is crucial, but the methods available for indirect null allele detection return inconsistent results. Here, our aim was to compare different methods for null allele detection, to explain their respective performance and to provide improvements. We applied several approaches to identify the 'true' null alleles based on the predictions made by five different methods, used either individually or in combination. First, we introduced simulated 'true' null alleles into 240 population data sets and applied the methods to measure their success in detecting the simulated null alleles. The single best-performing method was ML-NullFreq_frequency. Furthermore, we applied different noise reduction approaches to improve the results. For instance, by combining the results of several methods, we obtained more reliable results than using a single one. Rule-based classification was applied to identify population properties linked to the false discovery rate. Rules obtained from the classifier described which population genetic estimates and loci characteristics were linked to the success of each method. We have shown that by simulating 'true' null alleles into a population data set, we may define a null allele frequency threshold, related to a desired true or false discovery rate. Moreover, using such simulated data sets, the expected null allele homozygote frequency may be estimated independently of the equilibrium state of the population.
Data from: Microsatellite loci for dreissenid mussels (Mollusca: Bivalvia: Dreissenidae) and relatives: markers for assessing exotic and native populations
We developed and tested 14 new polymorphic microsatellite loci for dreissenid mussels, including the two species that have invaded many freshwater habitats in Eurasia and North America, where they cause serious industrial fouling damage and ecological alterations. These new loci will aid our understanding of their genetic patterns in invasive populations as well as throughout their native Ponto-Caspian distributions. Eight new loci for the zebra mussel Dreissena polymorpha and six for the quagga mussel D. rostriformis bugensis were compared with new results from six previously published loci to generate a robust molecular toolkit for dreissenid mussels and their relatives. Taxa tested include D. polymorpha , D. r. bugensis , D. r. grimmi , D. stankovici , the "living fossil" Congeria kusceri , and the dark false mussel Mytilopsis leucophaeata (the latter also is invasive). Overall, most of the 24 zebra mussel (N=583) and 13 quagga mussel (N=269) population samples conformed to Hardy-Weinberg equilibrium expectations for the new loci following Bonferroni correction. The 11 loci (eight new, three previously published) evaluated for D. polymorpha averaged 35.1 alleles and 0.72 mean observed heterozygosity per locus, and 25.3 and 0.75 for the nine loci (six new, three previously published) developed for D. r. bugensis . All but three of these loci successfully amplified the other species of Dreissena , and all but one also amplified Congeria and Mytilopsis . All species and populations tested were significantly divergent using the microsatellite data, with neighbor-joining trees reflecting their evolutionary relationships; our results reveal broad utility for resolving their biogeographic, evolutionary, population, and ecological patterns.
