Ethnic Nationalism and Adaptation in Cyprus

Both ethnic communities in Cyprus have maintained strong political and cultural ties with Greece and Turkey, respectively, and at some point of their twentieth century history, each has aspired to become part of either the former or the latter. Yet the way this relationship has been imagined has differed across time, space, and class. Both communities have adapted their identities to prevailing ideological waves as well as political opportunities, domestic alliances, and interests. The article evaluates different responses to ethnic nationalism, highlighting important intra-ethnic differentiations within each Cypriot community usually expressed in the positions of political parties, intellectuals, and the press. While the current literature identifies two major poles of identity in the island, "motherland nationalism" and "Cypriotism," the article suggests that the major focus of identity of Cypriots is identification with their respective ethnic communities in the form of Greek Cypriotism or Turkish Cypriotism. In fact, contentious politics in Cyprus from the ENOSIS/TAKSIM struggle to the April 2004 referendum demonstrate the interplay of external constraints and collective self-identification processes leading to the formation of these identities. The article concludes by identifying the implications of identity shifts for deeply divided societies and conflict resolution in general.

Habitat-specific adaptation of immune responses of stickleback (Gasterosteus aculeatus) lake and river ecotypes

Freshwater populations of three-spined sticklebacks (Gasterosteus aculeatus) in northern Germany are found as distinct lake and river ecotypes. Adaptation to habitat-specific parasites might influence immune capabilities of stickleback ecotypes. Here, naive laboratory-bred sticklebacks from lake and river populations were exposed reciprocally to parasite environments in a lake and a river habitat. Sticklebacks exposed to lake conditions were infected with higher numbers of parasite species when compared with the river. River sticklebacks in the lake had higher parasite loads than lake sticklebacks in the same habitat. Respiratory burst, granulocyte counts and lymphocyte proliferation of head kidney leucocytes were increased in river sticklebacks exposed to lake when compared with river conditions. Although river sticklebacks exposed to lake conditions showed elevated activation of their immune system, parasites could not be diminished as effectively as by lake sticklebacks in their native habitat. River sticklebacks seem to have reduced their immune-competence potential due to lower parasite diversity in rivers
