Journal Title: Journal of Agricultural and Crop Research - Year 2018, Vol 6, Issue 3
Abstract
This article investigates the malacological diversity of five Lamiaceae in the region of Tlemcen (Northwest Algeria). Its arid climate leads to open formation degradation of vegetation. The doum palm is widely distributed in this region as well other aromatic species such as: rosemary, thyme, lavender crocus and horehound. The four aromatic species mentioned above belong to the Labiatae family based on their morphological and botanical characteristics and are certainly an importance source for this malacological fauna. This study proposes an approach to find the diversity of malacofauna identified in these Lamiaceae. For this, an inventory was made in different stations. Malacological wealth of thyme is estimated at 19; rosemary, 18; lavender, 14; Salvia, 9, and lastly, horehound, 7. They belong to four families namely Milacidae, Sphincterochilidae, Helicidae and Subulinidae. The Milacidae have horehound and lavender. In this case, Sphincterochilidae, Sphincterochila candidissima do not have lavender, Salvia and horehound. Subulinidae family has one species: Rumina decollata. Helicidae specifically has the richest two subfamilies: Helicinae and Helicellinae. The first subfamily consists of 11 species of thyme, 10 species of rosemary and 5 of lavender, 4 of horehound and 2 of Salvia. The second subfamily comprises 7 lavender, 6 species respectively of thyme and rosemary, 5 salvia and one horehound. This study also tries to investigate the molluscan species specific to each of these plants that are common. Finally, the vertical distribution of gastropods is given.
