Parasites are important in understanding population dynamics and ecology of hosts. In
several Mediterranean islands, little is known about lizards' blood parasites. We studied the
relations between haemoparasites and an endemic lizard host, Podarcis lilfordi (Günther,
1874) on Aire Island (Menorca, Balearic Islands, Spain). The infection intensity was about

than in continental populations of the genus Podarcis. The reduced genetic variability and/or …
