ΣΥΝΕΙΣΦΟΡΑ ΣΤΗ ΜΕΛΕΤΗ ΤΗΣ ΟΙΚΟΦΥΣΙΟΛΟΓΙΑΣ ΤΟΥ ΓΑΣΤΕΡΟΠΟΔΟΥ ΠΝΕΥΜΟΝΟΦΟΡΟΥ HELIX LUCORUM L.

THE STUDIES OF BIOLOGY, ECOLOGY, ETHOLOGY, BIOMETRY, ENERGY BUDGET AND EXCRETION HAVE SHOWN THAT HELIX LUCORUM L. FROM GREECE IS CHARACTERIZED A) BY THREE GENERATIONS PER YEAR, B) IT MAY LIVE 14 YEARS OR MORE IN ORDER TO REACH ITS MAXIMUM SIZE, C) IT IS SEXUALLY MATURE WHEN THE LARGEST SHELL DIAMETER D) IN GREATER OR EQUAL TO 36MM, SIZE ATTAINED 3 YEARS AFTER ITS HATCHING, D) ITS HIBERNATION LASTS 4-5 MONTHS, E) ITS REPRODUCTIVE PERIOD IS FROM JULY TO AUGUST, IT LAYS ABOUT 50 EGGS, F) ITS MEAN ANNUAL DENSITY IS 3.39 INDIVIDUALS/M2, G) ITS ANNUAL TURNOVER RATIO (P/B) IS EQUAL TO 1.24, H) ITS ASSIMILATION RATE (A/I) IS GREATERWHEN IT IS FED WITH LACTUCA SATIVA AND LESS WHEN IT IS FED WITH URTICA DIOICA OR PETASITES ALBUS; ITS COEFFICIENT OF GROWTH EFFICIENCY (P/I) AND ITS COEFFICIENT OF ECOLOGICAL EFFICIENCY (P/A) ARE GREATER WHEN IT IS FED WITH P. ALBUS ANDLESS WHEN IT IS FED WITH U. DIOICA OR L. SATIVA. THE ABOVE PARAMETERS ASCILLATE WITH THE AGE, THE SEASON OR THE PHYSIOLOGY OF THE ANIMALS. I) H. LUCORUM IS URICOTELIC ALTHOUGH ITS URICOTELIC CHAIN IS COMPLETE.
