Investigating the Behaviour and Ecology of the Glutinous Snail Myxas glutinosa in Field Conditions in Llyn Tegid (2016)

  • All

The Glutinous Snail Myxas glutinosa is an aquatic species restricted to a single known population in Britain located in Llyn Tegid. Following on from successful captive breeding experiments and their revelations, proposals were made to use the knowledge acquired to begin field experiments that might lead to improved understanding of Myxas natural ecology and appropriate management procedures. This report comprises the instigation of that work. The experiments proposed are a tentative method to probe into the life of Myxas and answer the following questions: Does Myxas migrate up and down the shore as lake levels recede and advance? Do changes in water level benefit or harm the snail population or are they benign? What substrates favour Myxas? What physicochemical differences occur across Llyn Tegid and what effect do they have on Myxas? Would Myxas benefit from the placement of refuges at particular sites around the lake and if so, where and of what material? Is it possible to manage habitats with simple methods that benefit Myxas and could be employed to return Myxas to its former range? We do not know exactly what the experiments will show us and they may disprove some existing theories but the author feels sure they will show us more than we already know and will help engage local workers, land-owners and others in Myxas conservation and study. The first stage has been completed with the installation of bespoke concrete refuges and a brief second inspection of these has already begun to provide some insight into the life of wild Myxas in the lake and an opportunity to begin mapping areas of the lake bed where Myxas occurs.
