Isolation and characterization of 17 polymorphic microsatellite loci in the kangaroo mouse, genus Microdipodops (Rodentia: Heteromyidae)

We isolated and characterized 17 microsatellite loci from kangaroo mice, Microdipodops megacephalus and M. pallidus. Loci were screened in 24 individuals from 21 general localities across their distributional range in the Great Basin Desert. In total, the number of alleles per locus ranged from 4 to 16, observed heterozygosity ranged from 0.333 to 1, and the probability of identity values ranged from 0.013 to 1. These loci provide new tools for examining the biogeographic history and population dynamics of Microdipodops in the context of molecular ecology.

253 Novel polymorphic microsatellites for the saltwater crocodile (Crocodylus porosus)

Genomic elucidation and mapping of novel organisms requires the generation of large genetic resources. In this study, 253 novel and polymorphic microsatellite loci were isolated and characterized for the saltwater crocodile (Crocodylus porosus) by constructing libraries enriched for microsatellite DNA. All markers were evaluated on animals obtained from Darwin Crocodile Farm in the Northern Territory, Australia, and are intended for future use in the construction of a genetic-linkage map for the saltwater crocodile. The 253 loci yielded an average of 4.12 alleles per locus, and those selected for mapping had an average polymorphic information content (PIC) of 0.425.

Isolation and characterization of microsatellite loci for Florida largemouth bass, Micropterus salmoides floridanus, and other micropterids.

We isolated and characterized 52 novel microsatellite markers from Florida largemouth bass, Micropterus salmoides floridanus, for use in conservation, management and population genetic studies. Markers were assessed in M. s. floridanus from peninsular Florida (n = 30) and averaged eight alleles per locus with observed heterozygosity of 0.57 (range 0–0.97). Cross‐taxa amplification was successful among 88% of tested congeners. These polymorphic and potentially taxon‐diagnostic markers contribute to the limited number of microsatellites currently available for micropterids and specifically M. s. floridanus.

Five Hundred Microsatellite Loci for Peromyscus

Mice of the genus Peromyscus, including several endangered subspecies, occur throughout North America and have been important models for conservation research. We describe 526 primer pairs that amplify microsatellite DNA loci for Peromyscus maniculatus bairdii, 467 of which also amplify in Peromyscus polionotus subgriseus. For 12 of these loci, we report diversity data from a natural population. These markers will be an important resource for future genomic studies of Peromyscus evolution and mammalian conservation.

Fifteen polymorphic microsatellite loci from Jamaican streamertail hummingbirds ( Trochilus )

We isolated and characterized 15 microsatellite loci from the endemic Jamaican streamertail hummingbird Trochilus polytmus. Loci were screened in 12 individuals of both T. polytmus and its sister species T. scitulus, also a Jamaican endemic. The number of alleles per locus ranged from 2 to 10, observed heterozygosity ranged from 0 to 1, and the probability of identity values ranged from 0.038 to 0.663. These new loci provide tools for characterizing the narrow hybrid zone between the two species.

Isolation and characterization of microsatellite loci in the Guanacaste tree, Enterolobium cyclocarpum

We isolated nine microsatellite loci from the Guanacaste tree (Enterolobium cyclocarpum) and optimized them for future research on breeding populations of this species. Loci were screened across 53 individuals from one population and were shown to be variable with the number of alleles per locus ranging from five to 15. Polymorphic information content ranged from 0.420 to 0.900 and observed heterozygosity ranged from 0.547 to 0.906.

PERMANENT GENETIC RESOURCES: Fifteen polymorphic microsatellite DNA loci from Hawaii's Metrosideros polymorpha (Myrtaceae: Myrtales), a model species for ecology and evolution

We developed 15 polymorphic microsatellite loci from the Hawaiian tree Metrosideros polymorpha. These loci were screened against two varieties from several populations and from 23 individuals from one mid‐elevation population on Hawaii Island. Loci were variable with the number of alleles per locus ranging from three to 24. Polymorphic information content ranged from 0.222 to 0.941, and observed heterozygosity ranged from 0.261 to 0.955.

Characterization of 10 microsatellite loci in an avian louse, Degeeriella regalis (Phthiraptera: Ischnocera: Philopteridae)

We isolated and characterized 10 polymorphic microsatellite loci in an ischnoceran louse, Degeeriella regalis, which parasitizes the threatened Galápagos hawk (Buteo galapagoensis) and other falconiform birds. The loci were screened across 30 individuals from two island populations in the Galápagos Islands. The number of alleles per locus ranged from two to 28. Polymorphic information content ranged from 0.14 to 0.94 and observed heterozygosity ranged from 0 to 0.67. These markers will be valuable in comparative population genetics studies in this species, which is the focus of a long‐term population and disease ecology research program.

Fifteen microsatellite loci for the jungle perch, Kuhlia rupestris

We developed and optimized 15 polymorphic microsatellite loci in the jungle perch, Kuhlia rupestris. Loci were screened in a single population (n = 24) from Fraser Island, Queensland, Australia. Number of alleles per locus ranged from 3 to 19 and observed heterozygosity from 0.25 to 1. No significant linkage disequilibrium was detected between any pair of loci. Genotype proportions for these loci in the population sampled were in Hardy–Weinberg equilibrium.

Novel microsatellite markers for the saltmarsh sharp-tailed sparrow, Ammodramus caudacutus (Aves: Passeriformes)

We have developed eight high‐quality microsatellite DNA loci for the saltmarsh sharp‐tailed sparrow and one additional locus with evidence of null alleles. In a sample of 250–350 individuals, the average number of alleles per locus was 14.7 and average observed heterozygosity was 0.80. These loci were tested in three additional species of emberizid sparrows, indicating that more than half of the loci could be useful in other sparrows.
