Rapid evolutionary responses in a translocated population of intertidal snail (Bembicium vittatum) utilise variation from different source populations

The artificial movement of individuals between populations (translocation) can be an
effective way to increase genetic diversity within populations, but few studies have …

Long‐term genetic monitoring reveals contrasting changes in the genetic composition of newly established populations of the intertidal snail Bembicium vittatum
