Crawford-Sidebotham goal was to gather information on the activity of several species of slugs, Arion hortensis, Arion subfuscus, Arion lusitancius, and Milax budapestensis. The goal of the study was to determine whether or not temperature and vapor pressure deficit played a role in the activity of the slugs. The experimental method used was the catch per unit. The sampling was conducted at night in …show more content…
The experiment tested the slugs’ preferred temperature, moisture, and food preferences. The three slug species he observed were Arion circumscriptus, Deroceras reticulatum, and D. laeve. All experiments were conducted in the slugs’ natural habitat, over the same area for a year and a half. The experiments showed that each slug species had different behaviors and two had no moisture preferences. Third slug species, A. circumscriptus, preferred more moisture. Other experiments were conducted in a lab to determine the slugs’ ability to deal with the cold. It was found that D. laeve had the ability to freeze completely and survive unthawing, while the other two species died. This article was important because it showed that while the species vary slightly from one another, they are still prefer similar
