STUDY OF THE CORRELATIONS BETWEEN MORPHOLOGIC PARAMETERS, AT TWO EDIBLE SNAILS POPULATIONS DEPENDING ON THE METABOLIC ACTIVITY STATUS
Keywords:
snails, the metabolic activity status, the biometric parametersAbstract
In the present study we calculated the correlations between the “alive” (green)
weight and the biometric parameters of the shell according to the geographical area
and the metabolic activity status. The biological material studied belongs to the
species Helix pomatia. var. Banatica. from two different areas: Pădurea Verde and
OraviŃa. At both studied populations. the measurements and weighing were made
depending on the metabolic activity status (with operculum or without operculum).
From the analysis of the correlations results that the “alive” weight has a large
positive correlation with the foot weight and the depth of the shell. in both snails
populations. regardless of the metabolic activity status (r > 0.5). In the case of snails
without operculum. all the biometrical parameters of the shell have a large positive
correlation with the “alive” weight (values between 0.50016 and 0.989085).
Negative correlations have been observed in the case of the snails with operculum.
between the alive weight and the shell height (r = 0.00231). and between the alive
weight and shell width (r = 0.00443).
