Microsatellite variation in ringed seals (Phoca hispida): genetic structure and history of the Baltic Sea population

Article Abstract:

Microsatellite variation in ringed seals (Phoca hispida) has been studied to investigate genetic structure and history of the Baltic Sea population. The population was compared to an Arctic reference population. Within the Baltic Sea no differentiation was found between the Gulf of Finland and the Gulf of Bothnia breeding areas. Population decline and split that have occurred recently have not affected inbreeding levels of the disjunct breeding stocks.

Population dynamics of the symbiotic mushroom Hebeloma cylindrosporum: mycelial persistence and inbreeding

Article Abstract:

Mycelial persistence and inbreeding are discussed with consideration of population dynamics of Hebeloma cylindrosporum, a symbiotic mushroom. The arrangement of fruit-bodies and genets of H. cylindrosporum point to the possibility that only a part of the sampled area favors colonization. Also it appears that genetic diversification through meiospore dispersal may be from resident genets, perhaps via a somatic incompatibility system.

Population genetics and dynamics of the black truffle in a man-made truffle field

Article Abstract:

Analyses of microsatellite and RAPD markers have been used for black truffle colonization dynamics in an artificial field. Very little genetic diversity was seen. Isolation by distance was not seen in the European range, corroborating the hypothesis of an impact by glaciation on genetic variation.
