title: Densities and morphology of two co-existing lizard species (Lacerta agilis and Zootoca vivipara) in extensively used farmland in Poland.
abstract: The study was carried out in extensive farmland area near the town of Odolanów, Poland. During two breeding seasons (April-May, 2006-2007) lizards were counted on transect routes and captured by hand or by noosing. In total, 123 specimens of L. agilis and 153 specimens of Z. vivipara were captured. The proportion of males to females wasn't differed from the theoretical 1:1 ratio. Almost half of the individuals exhibited tail autotomy at least once in life. In the studied sand lizards significant sex specific differences were found between all morphological traits, i.e. males were shorter, lighter, but had a bigger head. In common lizards significant sex specific differences were detected only in body length, i.e. females were longer. All of the morphological traits were highly inter-correlated.
