Development and characterization of microsatellite loci from the Great White Pelican (Pelecanus onocrotalus) and widespread application to other members of the Pelecanidae

We describe the isolation of 10 microsatellite loci from the Great White Pelican using an enrichment protocol. All loci were variable with the number of alleles ranging from 2 to 19, and observed heterozygosity ranging from 0.261 to 0.913. Two loci were out of Hardy–Weinberg equilibrium, although in each case this was restricted to one of the two populations screened. None of the loci were linked. Eight to 10 loci PCR-amplified in three related species: Brown, American White and Pink-backed Pelicans. These loci should prove to be widely applicable to studies of phylogeography and demography in pelicans globally.     

Development of ten highly polymorphic microsatellite markers for Sunbirds (Aves: Nectariniidae) with broad cross-amplification utility in at least eight species

We describe the isolation of ten microsatellite loci from the Rwenzori Double-collared Sunbird using an enrichment protocol. All loci were variable with the number of alleles ranging from 5 to 13, and observed heterozygosity ranging from 0.500 to 0.929. Nine of these loci were screened on a panel of seven additional Sunbird species from three genera. All nine were successfully amplified and remained highly variable. Given 10–15% sequence divergence among these species in the mtDNA ND2 gene, our results suggest that these markers will work broadly across most members of the species rich bird family Nectariniidae.     

PERMANENT GENETIC RESOURCES: Isolation and characterization of 10 tetranucleotide microsatellite loci in an enigmatic East African bird, the spot-throat (Modulatrix stictigula)

We describe the isolation of 10 tetranucleotide microsatellites from the spot-throat using an enrichment protocol. All loci were highly variable with the number of alleles ranging from six to 20 and observed heterozygosity ranging from 0.410 to 0.940. Although all loci were in Hardy-Weinberg equilibrium, locus Mst95 showed significant homozygote excess in both surveyed populations, possibly a consequence of the presence of null alleles at this locus. These loci will be used to determine the extent to which spot-throat populations are isolated in order to help set conservation priorities for this ancient African lineage.     

Isolation and characterization of 14 microsatellite loci for the Chevrier's field mouse (Apodemus chevrieri)

We describe the isolation and characterization of 14 microsatellite loci in the Chevrier's field mouse from genomic DNA-enriched libraries. The 14 loci were highly polymorphic with numbers of alleles per locus in 24 individuals ranging from three to 13, observed heterozygosity from 0.381 to 0.867 and expected heterozygosity from 0.448 to 0.931. All loci followed Hardy-Weinberg expectations except for CFM3, CFM10 and CFM12 loci. No significant linkage association was found among all these loci. The 14 polymorphic microsatellite loci will be useful in studying phylogeography and population genetics of the Chevrier's field mouse.     

Isolation of highly polymorphic autosomal microsatellite loci and a sex‐linked locus from sugarbirds

We describe the isolation of six tetranucleotide microsatellites from the Cape sugarbird (Promerops cafer) using an enrichment protocol. All loci were highly variable with number of alleles ranging from nine to 26 and values of observed heterozygosity ranging from 0.534 to 0.931. All loci were in Hardy–Weinberg equilibrium with the exception of Pro66 and Pro86. Further analysis of Pro86 indicated it was Z‐linked. All loci amplified and were variable in the congeneric Gurneys sugarbird (Promerops gurneyi). These loci will be used in mating system and phylogeographic studies of Cape sugarbirds in South Africa.     

Isolation and characterization of microsatellite loci in the beaver (Castor canadensis)

We have isolated and characterized 10 microsatellite loci in the beaver (Castor canadensis). Sixty individuals from southern and central Illinois were screened at each locus. All loci exhibited moderate levels of polymorphism, ranging from five to 13 alleles per locus with average heterozygosity ranging from 0.317 to 0.867. Locus Cca5 deviated significantly from HWE (P < 0.001). The locus pair Cca4/Cca5 was shown to be in linkage disequilibrium in southern Illinois, but not in the central Illinois population. The remaining eight loci will be useful in investigations of mating and kinship patterns in beaver populations in Illinois.     

Isolation, characterization and PCR multiplexing of polymorphic microsatellite markers in the edible dormouse, Glis glis

We isolated and characterized 10 dinucleotide microsatellite loci in the edible dormouse, Glis glis (Linnaeus). Four multiplex panels were developed. Loci were amplified in samples from two geographically distant populations (Torgny in Belgium and Montseny in Spain). All loci were polymorphic in Spain but four were monomorphic in Belgium. Individuals from Belgium and Spain exhibited an average allelic diversity of 1.9 and 3.3 and an observed heterozygosity ranging from 0.08 to 0.47 and from 0.04 to 0.72, respectively.     

Isolation and characterization of microsatellite loci in the Caribbean sea fan coral, Gorgonia ventalina

Here we report primers for 10 microsatellite loci from the Caribbean sea fan coral, Gorgonia ventalina. Primers were tested on 237 genomic DNA extracts taken directly from tissue samples of G. ventalina. All loci were polymorphic with allelic richness ranging from 4 to 52. Expected heterozygosity ranged from 0.14 to 0.96. Preliminary data suggest that these microsatellites will be useful tools for studies of the population genetics of this important Caribbean coral species.     

Characterization of Mauritius parakeet (Psittacula eques) microsatellite loci and their cross-utility in other parrots (Psittacidae, Aves)

We characterized 21 polymorphic microsatellite loci in the endangered Mauritius parakeet (Psittacula eques). Loci were isolated from a Mauritius parakeet genomic library that had been enriched separately for eight different repeat motifs. Loci were characterized in up to 43 putatively unrelated Mauritius parakeets from a single population inhabiting the Black River Gorges National Park, Mauritius. Each locus displayed between three and nine alleles, with the observed heterozygosity ranging between 0.39 and 0.96. All loci were tested in 10 other parrot species. Despite testing few individuals, between seven and 21 loci were polymorphic in each of seven species tested.     

Isolation and characterization of 11 polymorphic microsatellite loci in the millipede Antichiropus variabilis Attems (Diplopoda: Polydesmida: Paradoxosomatidae)

Eleven polymorphic microsatellite loci were isolated from the Western Australian millipede Antichiropus variabilis. The number of alleles observed ranged from 2 to 12, with observed heterozygosities ranging from 0.20 to 0.80. All loci were in Hardy-Weinberg equilibrium, and no pairs of loci were in linkage disequilibrium. Many of the loci amplified successfully in eight other Antichiropus species.     

Isolation and characterization of microsatellites in Drosophila montana and their cross‐species amplification in D. virilis

We report the isolation of 20 microsatellite loci from Drosophila montana and their cross amplification in the relative D. virilis. All microsatellite loci were polymorphic in the focal species D. montana, with gene diversities ranging from 0.23 to 0.93. In D. virilis only eight loci (40%) amplified and two loci were polymorphic (10%). These markers represent the first report of microsatellites isolated in D. montana. They could be applied for studying population structure and phylogeography. The largest benefit, however, will be their use in studies of quantitative trait loci, such as the mapping of behavioural quantitative trait loci.     

Isolation and characterization of 10 MHC Class I-associated microsatellite loci in tammar wallaby (Macropus eugenii)

The major histocompatibility complex (MHC) contain genes which play a key role in immune response and mate choice, and are therefore of functional importance to molecular ecologists. Here we describe the design of 10 MHC Class I-associated microsatellite loci from the tammar wallaby. All 10 loci are highly polymorphic, with the expected heterozygosity ranging from 0.547 to 0.919. Six loci successfully cross-amplify in other macropodid species. These microsatellites will serve as useful tools for studying the level of MHC diversity, the impact of selection on genetic variation and the unique structure of the tammar wallaby MHC.     

Isolation and characterization of novel polymorphic nuclear microsatellite markers from Ophrys fusca (Orchidaceae) and cross-species amplification

The present study reports the isolation and characterization of eight new polymorphic microsatellite loci from the sexually deceptive orchid Ophrys fusca. Microsatellites were isolated from two partially enriched genomic libraries using FIASCO (Fast Isolation by AFLP of Sequences COntaining repeats). Seventy-three loci were screened for primer design and primer pairs corresponding to eight different loci were selected for microsatellite characterization of two Portuguese populations. Total number of alleles per locus ranged from 10 to 32. All loci showed a high level of observed heterozygosity (H₀) ranging from 0.33 to 1 and were possible to amplify in 16 other species of Ophrys using the same primers. H. C. Cotrim and F. A. Monteiro have contributed equally to this work.     

Transferability and characterization of nine microsatellite markers for the tropical tree species Tabebuia roseo-alba

Microsatellite loci that were previously developed in the tropical tree Tabebuia aurea were used for the genetic analysis of Tabebuia roseo-alba populations. Nine of 10 simple sequence repeat markers were amplified, and the polymorphism was assessed in 58 individuals sampled from two stands in southeastern Brazil. All loci were polymorphic with Mendelian inheritance. The allele numbers were high, ranging from 5 to 13 in population I and 3 to 7 in population II, with means of 8.9 and 5.5, respectively. We conclude that these markers can be efficiently used for parentage and gene-flow studies.     

PERMANENT GENETIC RESOURCES: Isolation, characterization and multiplex genotyping of 11 autosomal and four sex-linked microsatellite loci in the reed bunting, Emberiza schoeniclus (Emberizidae, Aves)

Fifteen highly polymorphic microsatellite loci were characterized in the reed bunting, Emberiza schoeniclus. Eleven loci were autosomal and four linked to the Z chromosome. All loci were characterized and tested in 45 unrelated reed buntings from a Swiss population. Autosomal loci displayed seven to 17 and sex-linked loci displayed four to 13 alleles with heterozygosities ranging from 0.756 to 0.933 and from 0.478 to 0.957, respectively. These loci will be used in population genetic and mating system studies of reed buntings.     

Isolation and characterization of microsatellite loci in Symbiodinium B1/B184, the dinoflagellate symbiont of the Caribbean sea fan coral, Gorgonia ventalina

Here we report primers targeting 10 microsatellite loci of dinoflagellates in the genus Symbiodinium (clade B1/B184) symbiotic with the Caribbean sea fan coral, Gorgonia ventalina. Primers were tested on 12 Symbiodinium B1/B184 cultures, as well as 40 genomic DNA extracts of G. ventalina tissue samples. All loci were polymorphic with allelic richness ranging from 4-16. Gene diversity ranged from 0.15 to 0.91. These primers provide powerful tools for examining the fine-scale population structure and dynamics of Symbiodinium within a single host species.     

Isolation and characterization of 12 microsatellites from the black surfperch, Embiotoca jacksoni, a reef fish that lacks a pelagic larval phase

A set of 12 microsatellite markers was developed from Embiotoca jacksoni genomic DNA and tested for polymorphism using 64 individuals from two populations. All loci were polymorphic with a number of alleles ranging from two to 19 with expected heterozygosities ranging from 0.17 to 0.89. There was no evidence of linkage disequilibrium and all loci were in Hardy-Weinberg equilibrium, except for four loci in one population. High numbers of private alleles were consistent with strong population structure, and very limited dispersal. Six microsatellite markers successfully cross amplified and were polymorphic in closely related species, Embiotoca lateralis and Hyspurus caryi.     

Autosomal and sex-linked microsatellite loci in the green oak leaf roller Tortrix viridana L. (Lepidoptera, Tortricidae)

Eight microsatellite markers were developed for the lepidopteran species Tortrix viridana using an enrichment protocol. The loci were highly variable with number of alleles ranging from four to 38. Six of the eight loci were in Hardy-Weinberg equilibrium. The other two were linked to the Z-chromosome. Values of observed heterozygosity ranged for the autosomal loci from 0.510 to 0.957. All loci will be useful to study dispersal and the autosomal loci, as well for phylogeographical studies.     

Isolation and characterization of microsatellite loci from the orchid Serapias vomeracea (Orchidaceae) and cross‐priming to other Serapias species

In this paper we describe the isolation and characterization of six polymorphic microsatellite loci from the orchid Serapias vomeracea. This species is widely distributed in the Mediterranean region. Microsatellite loci were isolated from an enriched library and primer pairs were designed for 18 loci. Primer pairs for six loci amplified well and were tested on samples from southern Italy. Levels of genetic variability detected at these six loci are high, with numbers of alleles per locus ranging from 3 to 6, and observed heterozygosity (H_O) ranging from 0.35 to 0.86. All primer pairs tested amplified DNA from four other Serapias species, indicating that the primers are useful for population genetic studies throughout the genus.
