The Caspian lizard (Darevskia caspica) is a recently described endemic of the Hyrcanian forests Northern Iran. paper presents new data on reproductive biology D. caspica obtained in laboratory conditions. Breeding females have body length 53.4– 64.4 mm and mass 2.96–3.60 g. Females produce from one to three clutches per season, each which contains 1–6 eggs. these eggs 10.35–13.95 mm, width 6.19...

Management practices/strategies to re-modulate the wild behaviour of animal species could increase their number in natural areas. The captive herd hog deer showed slight changes from due stress with no alteration pattern except stress. Adult males (6), adult females (6) and fawns were selected observed round clock for thirty days across season after one-hour interval on each activity. All subje...

1. Development in organisms can vary in response to fluctuating environments. In holometabolous insects, variation in adult phenotypic traits is strongly influenced by growth conditions experienced by larvae. The main aim of this study was to assess how much environmental insight can be gained from analysis of the phenotypic changes in an insect’s life history parameters in response to realisti...
