Isolation of seven polymorphic microsatellites in Ophioblennius atlanticus atlanticus (Perciformes, Blenniidae)
We isolated and characterized seven polymorphic microsatellite loci of Ophioblennius atlanticus atlanticus (Valenciennes, 1836) using an optimized protocol to construct and screen a microsatellite-enriched genomic library. The analysis of variability was performed in 16 specimens from Faial Island (Azores, Portugal). The mean number of alleles was 8.71 ± ± ± 2.43 and the level of expected heterozygosity ranged from 0.764 to 0.903. The total exclusionary probabilities using these loci for the first and the second parent were 0.985 and 0.998, respectively, suggesting that these microsatellites are a useful tool for large-scale parentage analysis.
Mediterranean bioconstructions along the Italian coast
Marine bioconstructions are biodiversity-rich, three-dimensional biogenic structures, regulating key ecological functions of benthic ecosystems worldwide. Tropical coral reefs are outstanding for their beauty, diversity and complexity, but analogous types of bioconstructions are also present in temperate seas. The main bioconstructions in the Mediterranean Sea are represented by coralligenous formations, vermetid reefs, deep-sea cold-water corals, Lithophyllum byssoides trottoirs, coral banks formed by the shallow-water corals Cladocora caespitosa or Astroides calycularis, and sabellariid or serpulid worm reefs. Bioconstructions change the morphological and chemicophysical features of prima…

Development and characterization of 11 microsatellite markers in the rock sparrow, Petronia petronia
Eleven polymorphic microsatellite loci were isolated in the passeriform Petronia petronia using the enrichment protocol FIASCO (fast isolation by AFLP of sequences containing repeats). We detected three to 13 alleles per locus in 25 specimens collected from an Italian population. The level of expected heterozygosity ranged from 0.439 to 0.856. One locus is sex linked to the Z chromosome. The total exclusionary probabilities using these loci for the first and the second parent were 0.978 and 0.999, respectively. These are the first microsatellite loci characterized from the rock sparrow that can be used for estimating population structure and for large-scale parentage analysis.
