Across Europe there are many different institutes and traditions for organic farming research that until now have not been coordinated. Many of the research groups involved are geographically isolated and lack critical mass . 

Historically, 5. japonicum has been considered to be a genetically diverse parasite with different geographic isolates showing variation in snail host specificity (Chiu, 1967), pathogenicity and development (Hsu and Hsu, 1962), morphology (Sobhon et al., 1986) and...

In addition, access to closed cities is regulated. Many of the closed cities and weapons-related facilities are geographically located in remote areas, making contact with personnel difficult. The location of facilities in more isolated, less populated, and predominately Slavic areas also makes it more difficult for foreigners to operate without being noticed. Geographic isolation in Russia is reinforced by the difficulty of travel in rural Russia.

Sexual isolation has arisen among numerous species of geographically isolated populations of salamanders (review by Arnold et al., 1993). Behavioral experiments indicate that the degree of reproductive isolation is stronger between sympatric species of large Plethodon than it is between allopatric populations of these species (Reagan, 1992). Sexual isolation may be due to species-specific differences in the chemosensory systems...
