The objective of this study was to determine how temperature affects the activity level of Cepaea nemoralis. Both experiments showed the same relative trend of increased movement in a warm environment as opposed to decreased movement in a cold environment. Both tests showed a much greater average distance traveled in a minute in a hot environment than in a cold environment. However, many snails showed no activity in a cold environment by retracting into their shells and whenever hot, cool water was added to the hot treatment to keep the temperature stable, the snails became agitated and began to crawl. on the walls of the glass bowl. Generally, the temperature of 30 degrees Celsius increases the locomotion of snails, and 5 degrees Celsius limits their ability to move. In one study, it was concluded that muscle contraction is inhibited by low temperatures. We therefore predicted that C. nemoralis would move much faster when exposed to high temperatures than when exposed to lower temperatures (Holewijn & Heus, 1992). Our results were consistent with our predictions because in both trials, C. nemoralis on average traveled a greater mean distance in the hot treatment than in the cold treatment. These results are in agreement with the results of a similar experiment that tested the effect of temperature during the locomotion of Lymnaea stagnalis, a close relative of C. nemoralis (Sidorov, 2000). The experiment showed that snails moved at an average speed of 1.4 mm/s at temperatures ranging from 4 to 6 degrees Celsius, while some snails moved at an average speed of 5.4 mm/s at temperatures ranging from 24 to 26 degrees Celsius. In our experiment, the average moving speed was 2.38 mm/s at 5 degrees Celsius......in the middle of the paper habitat......l, or how much more or less they could travel overnight at a given temperature. temperature. It's possible that the fluorescent light in the classrooms agitated the snails, causing a change in their behavior. To remove this constraint in future studies, experiments should be conducted in dark environments, but not in completely dark rooms, as this would prove difficult to measure the length of the snail's path. In conclusion, our results showed that, overall, an increase in ambient temperature leads to an increase in ambient temperature. activity levels of Cepaea nemoralis. Likewise, a cold ambient temperature has been shown to decrease one's activity level. It was also found that larger snails traveled further in both heat treatments than smaller snails and that snails exposed to the cold treatment (5 degrees Celsius) showed signs of endogenous aestivation (hibernation).
