Isolation and characterization of 22 polymorphic microsatellite loci for the Barrow's goldeneye (Bucephala islandica)

We describe primers and polymerase chain reaction conditions to amplify 22 microsatellite loci from the Barrow's goldeneye (Bucephala islandica). The primers were tested on 27 individuals from a population breeding in British Columbia, Canada. The developed primer pairs yielded an average of 6.11 alleles per locus (range 2-12), an average observed heterozygosity of 0.70 (range 0.07-0.96) and a polymorphic information content of 0.07-0.88.     

Development of twenty-five polymorphic microsatellite markers for the endangered red-cockaded woodpecker (Picoides borealis)

Twenty-five polymorphic microsatellite markers were developed for the endangered red-cockaded woodpecker (Picoides borealis). The number of alleles ranged from two to five and observed heterozygosities ranged from 0.036 to 0.750. These loci should be useful tools for conducting research towards the management and conservation of this species.     

Isolation and characterization of 100 polymorphic microsatellite loci for the Siberian jay (Perisoreus infaustus)

We describe primers and polymerase chain reaction conditions to amplify 100 microsatellite loci from the Siberian jay (Perisoreus infaustus). The primers were tested on two geographically separated Finnish populations. The developed primer pairs yielded an average of 4.72 alleles per locus (range one to 17) and an average observed heterozygosity of 0.55 (range 0.04 to 1).     

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).     

Isolation and characterization of polymorphic microsatellite loci for the northern flicker (Colaptes auratus; Aves)

To investigate the mating system of northern flickers (Colaptes auratus), we developed primers for 14 microsatellite loci and screened them in 68 unrelated adults and their offspring. All markers were highly polymorphic with 9 to +36 alleles per locus. One marker was Z‐chromosome linked; one marker exceeded the size standard range and could not be analysed further. We checked the other 12 markers for Mendelian inheritance in 36 broods for which the social parents were known. Seven markers showed evidence for the presence of null alleles, and three of those showed significant deviation from Hardy–Weinberg equilibrium. Markers were generally unlinked.     

PERMANENT GENETIC RESOURCES: Isolation and characterization of 12 microsatellite markers in the middle-spotted woodpecker (Dendrocopos medius)

Twelve polymorphic microsatellite loci were developed for Dendrocopos medius. Polymorphism was assessed for 27 individuals from the southwesternmost population of this woodpecker species. The number of alleles per locus ranged from three to seven, with observed heterozygosity values from 0.444 to 0.852. Genotypic frequencies conformed to Hardy-Weinberg equilibrium, and no evidence for linkage disequilibrium was observed. Multilocus genotypes resulting from this set of markers will be useful to determine genetic diversity and differentiation within and among habitat patches inhabited by D. medius. Three of the loci were polymorphic for Picoides articus.     

Isolation and characterization of microsatellite DNA primers in burrowing owl (Athene cunicularia)

We developed polymerase chain reaction (PCR) primers to amplify 22 microsatellite DNA loci in burrowing owls (Strigiformes: Athene cunicularia). The seven most easily amplified and scored polymorphic loci are presented. These show 3?19 alleles per locus and expected heterozygosities of 0.067–0.712. Inheritance at all loci conformed to Mendelian expectations among six owl families, and six loci conform to Hardy–Weinberg expectations.     

Isolation and characterization of 30 polymorphic microsatellite loci from the mycophagous fly Drosophila innubila

Drosophila innubila is a mushroom-feeding member of the quinaria group, found in the woodlands and forests of the 'sky islands' in Arizona and New Mexico and extending south into central Mexico. Here, we describe and characterize 30 polymorphic microsatellite loci from D. innubila collected in the Chiricahua Mountains in Arizona. The number of alleles ranged from three to 21, and observed heterozygosity ranged from 0.0513 to 0.9737. Six loci were putatively X-linked, six departed from Hardy-Weinberg equilibrium, seven had evidence of null alleles, and six showed evidence of linkage disequilibrium. These markers will be useful for examining population structure of D. innubila and its association with male-killing Wolbachia.     

Isolation and characterization of polymorphic microsatellite loci for the three-toed box turtle (Terrapene carolina triunguis) and cross-amplification in other Terrapene species

We isolated and characterized eight polymorphic microsatellite loci for a Texas population of three-toed box turtle, Terrapene carolina triunguis, using a refined hybridization capture procedure. All eight primer pairs amplified successfully at all loci in seven Texas ornate box turtles (T. ornata ornata). Due to the decline and conservation concerns of North American box turtles, these isolated microsatellites may be a most valuable tool for evaluating baseline population genetic structure for threatened box turtle populations.     

Identification and characterization of 14 polymorphic microsatellite loci for a member of the Herpestidae (Mungos mungo)

In most cooperative breeders, reproductive skew is high. However, in the banded mongoose, Mungos mungo, multiple females reproduce concurrently within a social group, indicating that skew is relatively low in this species. In order to evaluate the degree of reproductive skew in the banded mongoose, we identified 14 polymorphic microsatellite loci for parentage analysis. Markers were found to have low levels of variability in this cooperative breeder, and several loci were found to be polymorphic in another member of the Herpestidae, the slender‐tailed meerkat (Suricata suricatta). For the banded mongoose, this suite of polymorphic loci provides a paternity exclusion of over 90%.     

Characterization of seven polymorphic microsatellite loci in the Common Loon (Gavia immer)

We describe polymerase chain reaction (PCR) primers and conditions to amplify seven microsatellite DNA loci isolated from the Common Loon (Gavia immer). The PCR primers were tested on 83 individuals from 10 locations in North America, including breeding, migration stopover, and wintering areas. Between two and seven alleles were observed to segregate at the seven microsatellite loci, with observed heterozygosities ranging from 0.048 to 0.695.     

Identification and characterization of 21 polymorphic microsatellite loci from the mycophagous fly Drosophila neotestacea

Drosophila neotestacea is a mushroom‐feeding fly that is common in the temperate and boreal forests of North America. Here I describe the isolation and characterization of 21 polymorphic microsatellite loci from the D. neotestacea genome. In a sample of flies from Rochester, New York, the expected and observed heterozygosities ranged from 0.344 to 1.000 and from 0.384 to 0.923, respectively. Of the 21 markers, six were likely X‐linked, seven showed a departure from Hardy–Weinberg equilibrium, and none were found to be in linkage disequilibrium. These loci will facilitate future ecological and population genetic studies of D. neotestacea.     

Isolation and characterization of polymorphic microsatellite loci from Brandt's voles (Lasiopodomys brandtii)

Ten polymorphic microsatellite loci from Lasiopodomys brandtii have been isolated and characterized. Two to 11 alleles per locus were detected from 52 Brandt's voles samples collected from a single population. Expected heterozygosities ranged from 0.406 to 0.840. For the majority of loci observed heterozygosities were similar to or greater than the expected heterozygosity. One locus pair appeared to be in linkage disequilibrium. The microsatellite markers will enable the studies of genetic diversity, population structure and relatedness in this species, and perhaps in closely related species of vole.     

Isolation and characterization of 15 polymorphic microsatellite DNA loci from Argyrosomus japonicus (mulloway), a new aquaculture species in Australia

Fifteen microsatellite loci were isolated for population genetic studies of mulloway (Argyrosomus japonicus), a commercial/recreational fish species in Southern Australia. A genomic library was screened randomly for di- tri- and tetranucleotide repeats. Fifteen microsatellite marker loci were developed that were highly polymorphic (allele number ranged from four to 18). Observed and expected heterozygosities ranged from 0.17 to 1 and from 0.27 to 0.91, respectively. These markers have proven useful for estimating genetic variation and for evaluating population structure across the species' natural distribution. They also provide powerful tools for optimizing hatchery practices to conserve genetic diversity.     

Isolation and characterization of polymorphic nuclear microsatellite loci in Pinus cembra L

We developed eight polymorphic nuclear microsatellite markers for the Swiss stone pine (Pinus cembra L.), of which seven may be amplified in a multiplex polymerase chain reaction. Allelic polymorphism across all loci and 40 individuals representing two populations in the Swiss Alps was high (mean = 7.6 alleles). No significant linkage disequlibrium was displayed between pairs of loci. Significant deviation from Hardy–Weinberg equilibrium was revealed at three loci in one population. Cross–amplification was achieved in two related species within the genus (P. sibirica and P. pumila). Thus, the markers may be useful for population genetic studies in these three pine species. They will be applied in ongoing projects on genetic diversity and patterns of gene flow in P. cembra.     

Isolation and characterization of 27 polymorphic microsatellite loci for the common snook,Centropomus undecimalis

Here we describe 32 di‐, tri‐ and tetranucleotide microsatellite loci isolated by PIMA, a polymerase chain reaction (PCR)‐based procedure, for the common snook (Centropomus undecimalis). Five loci were monomorphic, and the remaining loci averaged 6.7 alleles per locus in a sample of 45 common snook. For polymorphic loci, expected heterozygosities ranged from 0.02 to 0.91 (mean = 0.538). Significant departures from Hardy–Weinberg equilibrium expectations occurred in two loci. Exact tests for genotype disequilibrium gave evidence for linkage at one pair of loci. Many cross‐species primer assays yielded PCR fragments of the expected size for 11 species of Centropomus and two species of the confamilial genus Lates.     

Isolation of 10 tetranucleotide microsatellite loci in the blackcap (Sylvia atricapilla)

We isolated 10 polymorphic microsatellite DNA loci from the blackcap (Sylvia atricapilla) and optimized them for future studies of population differentiation in populations with different migration strategies in southwestern Germany. The loci were screened for polymorphism using 178 individuals from two populations in Germany and Spain. The primers amplified highly variable loci characterized by two to 19 alleles per locus and their observed and expected heterozygosities range from 0.47 to 0.81 and from 0.50 to 0.91, respectively.     

Characterization of polymorphic microsatellite loci for the invasive monk parakeet (Myiopsitta monachus)

Microsatellite loci were characterized for the monk parakeet (Myiopsitta monachus) from a GT_n‐enriched genomic library. Twelve of 14 microsatellite loci were polymorphic, averaging 6.7 alleles per locus across the 20 individuals genotyped. Mean expected heterozygosity was 0.72, with locus‐specific values ranging from 0.53 to 0.90. An equally high multilocus probability of identity (2.48 × 10^?12) was revealed for this set of loci. In addition, all 12 loci were demonstrated to cross‐amplify to varying extents within three additional parrot genera suggesting their potential utility for population‐level studies in a broad range of Neotropical psittacines.     

Isolation and characterization of nine microsatellite loci from the pike-perch, Sander lucioperca (Linnaeus, 1758)

In order to facilitate studies on the genetic structure of wild populations as well as to monitor genetic changes in cultured stocks, nine polymorphic microsatellite loci were isolated from pike-perch (Sander lucioperca). Single loci allele numbers varied between two (loci MSL-3 and MSL-7) and six (loci MSL-1 and MSL-2), and observed heterozygosities ranged from 0.36 (locus MSL-2) to 1.00 (locus MSL-9) in a test panel of 25 individuals. Only one pair of loci (MSL-5 and MSL-8) displayed significant linkage disequilibrium after sequential Bonferroni corrections. Hardy-Weinberg tests revealed significant excesses of heterozygotes at three loci (MSL-1, MSL-7, and MSL-9).
