Microsatellite loci for behavioural studies of rainbow bee‐eaters (Merops ornatus: Aves)

A set of polymorphic microsatellite loci was identified for population and behavioural studies of the rainbow bee‐eater (Merops ornatus). Eight loci were newly isolated from a rainbow bee‐eater genomic library enriched for GA‐containing repeats, and six loci from those previously reported for the European bee‐eater (Merops apiaster). From these two sources, the seven most variable loci that amplified reliably were unlinked and in Hardy–Weinberg equilibrium, had five to 13 alleles (mean 7.7) and an expected heterozygosity of 0.60–0.86 (mean 0.73).     

Polymorphic microsatellite loci for paternity analysis in the Madagascar paradise flycatcher (Terpsiphone mutata: Aves)

Nine polymorphic microsatellite loci from the Madagascar paradise flycatcher Terpsiphone mutata were isolated using nonradioactive polymerase chain reaction (PCR)‐based techniques to screen an enriched genomic library. Seven polymorphic loci showed no evidence of null alleles and exhibited high levels of variation in 18 unrelated individuals (mean diversity = 0.80, mean number of alleles = 13.6). These loci are therefore suitable for analysis of population structure and paternity (exclusion probability for six unlinked loci = 0.9998).     

Isolation of polymorphic microsatellite loci from Eurasian woodcock (Scolopax rusticola) and their cross‐utility in related species

We isolated one trinucleotide and seven tetranucleotide microsatellite loci for the Eurasian woodcock (Scolopax rusticola). We describe polymerase chain reaction conditions and primers for the successful amplification of these loci and report the results obtained from their use in 42 specimens from two populations in Europe. The number of alleles per locus ranged from three to 15, observed heterozygosity was comprised between 0.11 and 1.00 and expected heterozygosity ranged between 0.10 and 0.91. Cross‐specific amplification experiments highlighted the potential usefulness of these molecular markers for the study of three related scolopacid waders.     

Polymorphic microsatellite loci in Linum usitatissimum

We report the characterization of 28 polymorphic microsatellite markers in Linum usitatissimum that allow distinguishing almost all cultivars of both flax and linseed. Polymorphism was low, ranging from two to 10 alleles per locus in the 93 cultivars screened. Linkage disequilibrium was found at about a third of the pairs of loci likely due to self‐fertilization and strong selection by breeders. We tested these loci for cross‐amplification in nine additional species of Linum and found that three species amplified a majority of loci.     

Characterization of polymorphic microsatellite loci in Castelnau's Antshrike,Thamnophilus cryptoleucus (Aves: Thamnophilidae)

In order to study the biogeography and population genetic structure of the obligate river‐island species Thamnophilus cryptoleucus (Thamnophilidae) we isolated four microsatellite loci. Number of alleles ranged from six to 11, heterozygosities from 60% to 89%, and individual populations were found in Hardy–Weinberg equilibrium. Cross‐species amplification of the loci was tested in eight species of the family Thamnophilidae and all loci successfully amplified in five or more related species.     

Polymorphic microsatellite loci for the ant-garden ant, Crematogaster levior (Forel)

Throughout Amazonia, the ant Crematogaster levior is known for its participation in a complex ant-garden mutualism with the ant Camponotus femoratus and several species of epiphytic plants for which it plays an important role in seed viability. We isolated nine polymorphic microsatellite loci for C. levior from a genomic library enriched for di-, tri-, and tetra-nucleotide repeats. Two to 14 alleles were detected per locus, with levels of observed heterozygosity ranging from 0.103 to 0.785.     

Isolation and characterization of eight microsatellite loci in Leporinus macrocephalus (Characiformes: Anostomidae) and cross‐species amplification

Leporinus macrocephalus is a species endemic to the Paraguay River basin and an important fishery resource, as well as a valuable species in aquaculture programs. A total of eight polymorphic microsatellite loci were isolated and characterized. A population survey was conducted involving 45 specimens whereby a large number of alleles (range 5–17 among loci), a highly observed (0.1667–0.6129) and an expected (0.6967–0.9448) heterozygosity was detected, indicating its usefulness in population genetics studies. Cross‐species amplification was successful in eight Characiformes species.     

Polymorphic microsatellite loci for population studies of the Japanese scallop,Patinopecten yessoensis

Fifteen microsatellite loci were developed to examine the population structure of Japanese scallop, Patinopecten yessoensis. These markers were tested in samples from two geographically distant populations: the Sakhalin Island (Russia) and Dalian City (China). The mean numbers of alleles, observed and expected heterozygosities between the two populations were summarized by locus, but none of them show significant divergence between the two populations. Most loci conformed to Hardy–Weinberg expectation with the exception of loci HLJX‐06, HLJX‐12, HLJX‐13 and HLJX‐28, which had heterozygote deficits.     

Characterization of microsatellite loci In The hihi Notiomystis cincta (Notiomystidae, Aves)

We have characterized 20 polymorphic microsatellite loci in the hihi Notiomystis cincta. Loci were identified by testing loci originally isolated in other avian species and by isolating new microsatellites from a hihi genomic library. These loci were characterized in unrelated hihi from a single population on Tiritiri Matangi Island (n = 98). Each locus displayed between two and 10 alleles, and observed heterozygosities ranged between 0.29 and 0.91. Nineteen of the 20 polymorphic loci could be assigned a chromosome location in the zebra finch, Taeniopygia guttata genome based on sequence homology.     

Isolation and characterization of microsatellite markers in the southern emu‐wren (Stipiturus malachurus: Aves)

We isolated and characterized eight novel microsatellite loci in the southern emu‐wren (Stipiturus malachurus). We used nonradioactive polymerase chain reaction (PCR)‐based techniques to screen an enriched genomic DNA library. Based on genotypes from a single population, six loci showed no evidence of null alleles and were polymorphic (allele range = 2–9, mean heterozygosity = 0.57), and one locus was sex‐linked (N_A = 4). These loci were variable and had different allele size ranges in three other populations of southern emu‐wrens, and are therefore useful for determining levels of genetic diversity within and between populations of the species.     

PERMANENT GENETIC RESOURCES: Polymorphic microsatellite loci for Diachasma alloeum (Hymenoptera: Braconidae)

Here, we report the isolation of 21 novel primers for amplification of microsatellite loci in Diachasma alloeum (Hymenoptera: Braconidae). Diachasma alloeum is a larval parasitoid of the apple maggot fly (Rhagoletis pomonella), which is an economically significant agricultural pest species and a textbook example of sympatric speciation via host-plant shifting. These microsatellite markers will prove useful both for assessing genetic relationships between different host-associated populations of D. alloeum, as well as for future R. pomonella biological control programmes. We also report the cross-species amplification of several loci for Diachasmimorpha mellea and Diachasma ferrugineum, parasitoids of R. pomonella and R. cingulata, respectively.     

Fourteen polymorphic microsatellite loci characterized in the house sparrow Passer domesticus (Passeridae,Aves)

We characterized 14 polymorphic microsatellite loci in the house sparrow Passer domesticus. Four loci were isolated from house sparrow genomic libraries and 10 loci were identified by testing 100 loci that had been originally isolated in other passerine species. Loci were characterized in 37–54 unrelated sparrows from British and Norwegian populations. Each locus displayed between two and 31 alleles, with the observed heterozygosity ranging between 0.30 and 0.91.     

Microsatellite loci characterized in three African crane species (Gruidae, Aves)

Forty-three microsatellite loci originally isolated in Grus americana and G. japonensis were tested for polymorphism in the blue crane (G. paradisea). Amplified products were sequenced in the blue crane to aid in the design of blue crane-specific primers. When characterized in 20 unrelated blue crane individuals from South Africa, 14 loci were polymorphic, with each locus displaying between 2 and 7 alleles. Eight polymorphic loci were characterized in the grey-crowned crane (Balearica regulorum) and ten in the wattled crane (G. carunculatus).     

New microsatellite loci for Carcharhinid sharks (Carcharhinus tilstoni and C. sorrah) and their cross‐amplification in other shark species

Twelve microsatellite DNA markers were isolated in the spot‐tail shark (Carcharhinus sorrah) and nine were isolated in Australian black‐tip shark (Carcharhinus tilstoni). These loci plus 18 others developed for sharks from the genera Negaprion, Ginglymostoma, Carcharodon and Isurus were tested for amplification success on four species of Carcharhinus (including C. sorrah and C. tilstoni) and four other species representing three diverse families. Cross‐amplification was most common within families. Five loci were subsequently tested for polymorphism on 50 C. sorrah and 60 C. tilstoni. The number of alleles per locus was two to 24 and the average heterozygosity was 0.54 (range 0.16–0.87) for C. sorrah and 0.64 (range 0.44–0.78) for C. tilstoni. These loci may be useful tools for genetic analyses of the Carcharhinidae.     

Characterization of microsatellite loci in the lesser dawn bat (Eonycteris spelaea)

We constructed a genomic DNA library enriched for CA repeat motifs in Eonycteris spelaea. Nine microsatellite loci were isolated and tested on a population of 39 samples from Yunnan Province, China. These nine loci had three to 22 alleles per locus. Observed and expected heterozygosity values ranged from 0.079 to 0.963 and from 0.078 to 0.959. Two loci revealed significant departure from Hardy-Weinberg equilibrium and no linkage disequilibrium was found between loci pairs. These microsatellites can be a powerful molecular tool for population-level studies of E. spelaea.     

Isolation and characterization of microsatellite loci in Penstemon rostriflorus (Plantaginaceae) and cross‐species amplification

Eight novel microsatellite primer pairs are presented for Penstemon rostriflorus, representing the first microsatellite markers available for this genus. Loci were characterized for 20 individuals from two populations in the Great Basin, USA. All loci are polymorphic within P. rostriflorus (seven to 13 alleles per locus; observed heterozygosity between 0.40 and 0.95), and therefore useful for population genetic studies within the species. Cross‐species transferability was tested on 40 additional species of Penstemon, and results indicate that these primers pairs will likely be useful for population genetic studies on many Penstemon 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.     

Polymorphic microsatellite markers in Euryale ferox Salisb. (Nymphaeaceae)

Eleven polymorphic microsatellite markers were isolated and identified in the aquatic plant Euryale ferox Salisb. (Nymphaeaceae). This species, which belongs to basal Magnoliophyta, reproduces sexually. All of these 11 microsatellite markers yielded 25 alleles in a survey of a wild population of 34 individuals. Two or three alleles per locus were detected, with expected heterozygosity ranging from 0.056 to 0.634 and observed heterozygosity from 0.000 to 0.088. These simple sequence repeat markers will be useful for evaluating the genetic structure of the E. ferox population in the future.     

Isolation and characterization of polymorphic microsatellite loci from an EST library of turbot (Scophthalmus maximus) and cross‐species amplification

In the present study, we report 12 polymorphic microsatellite loci developed from a cDNA library from the turbot, Scophthalmus maximus. Observed and expected heterozygosities varied from 0.20 to 1.00 and from 0.18 to 0.78, respectively. No significant linkage disequilibrium between pairs of loci was found, but two loci significantly deviated from Hardy–Weinberg equilibrium after Bonferroni correction. Cross‐species amplifications of these microsatellites in five additional fish species revealed between five and 11 positive amplifications and between zero and four polymorphic loci per species.
