Microsatellite polymorphism in Italian populations of northern pike (Esox lucius L.)

Temporal changes and effective population size of an Italian isolated and supportive-breeding managed northern pike (Esox lucius) population

“…Genetic studies with allozymes (Healy and Mulcay, 1980;Seeb et al, 1987), mitochondrial DNA (Brzuzan et al, 1998;Maes et al, 2003;Nicod et al, 2004) and microsatellite markers Kapuscinski, 1996, 1997;Hansen et al, 1999;Senanan and Kapuscinski, 2000;Aguilar et al, 2005;Jacobsen et al, 2005;Laikre et al, 2005;Lucentini et al, 2006) revealed a low genetic polymorphism in this species. Microsatellites detected higher polymorphism with respect to other techniques (Laikre et al, 2005;Lucentini et al, 2006).…”

“…Although it is not considered an endangered species, recent studies indicate a decline of some North-European (Kovàcs et al, 2001;Westin and Limburg, 2002;Jacobsen et al, 2005) and Italian populations (Lorenzoni et al, 2002;Lucentini et al, 2006). Northern pike is a large, top predator and one of the most economically important freshwater fish for both recreational and commercial fisheries; it is also relevant for the conservation and management of freshwater ecosystems (Senanan and Kapuscinski, 2000;Kovàcs et al, 2001).…”

“…Northern pike is a large, top predator and one of the most economically important freshwater fish for both recreational and commercial fisheries; it is also relevant for the conservation and management of freshwater ecosystems (Senanan and Kapuscinski, 2000;Kovàcs et al, 2001). The effects of overfishing, habitat reduction and fragmentation, anthropic perturbations and climate changes, could constitute a risk for this species in Italy (Lorenzoni et al, 2002;Lucentini et al, 2006).…”

Isolation of microsatellite markers inSqualius lucumonis(Bianco, 1983) and cross-species amplification within the family Cyprinidae and other freshwater fish species

“…Heterozygosity values suggested that they constitute a valid tool for population genetic analyses in this species. In particular, considering the endemic nature of S. lucumonis, these loci might be employed in the assessment of population differentiation (Lucentini et al 2006b), in phylogeographic approaches aiming to compare this species with other congeneric, as well as in studies aiming to the evaluation of the effective populations size (Lucentini et al 2009). The recording of such information might be important not only as a basic knowledge of an endemic species, but also to perform scientifically supported management and conservation strategies.…”

Spatially explicit genetic structure in the freshwater sponge Ephydatia fluviatilis (Linnaeus, 1759) within the framework of the monopolisation hypothesis

“…this method is based on a simulated annealing procedure that aims at maximising the proportion of total genetic variance due to differences among groups of populations in a spatially explicit scenario. the geographical grouping of populations was performed for the microsatellite data following the procedure based on the hierarchical analysis of r St and maximising the total genetic variance proportion between the minimum (two) and the maximum (nine) number of groups in the dataset (r ct ), as described by Lucentini et al (2006a).…”
