Ecology of reptiles of Mordovian reserve

The material was collected on June 25-28, 2019. Five species of reptiles were found on the «Inorsky» cordon: Anguis fragilis , Lacerta agilis , Zootoca vivipara , Natrix natrix , Coronella austriaca . The most hygrophilic of these species is N. natrix , and the most xerophilic is L. agilis . The absolute numbers of the lizards L. agilis and Z. vivipara were calculated by tagging and secondary capture at two sites («Pavlovsky» cordon - 0,25 ha, «Noven'kiy» cordon - 0.20 ha). The absolute abundance of L. agilis at the first site was 81 individuals. (density 324 ind./ha), on the second site - 36 ind. (density 180 ind./ha). The absolute abundance of Z. vivipara at the first site was 12 ind. (density 48 ind./ha), on the second site - 47 ind. (density 235 ind./ha).
