''Adclarkia dawsonensis'' is a species of gastropod in the Camaenidae family. ''Adclarkia dawsonensis'' is the first identified species in the genus ''Adclarkia'' and is found in the Taroom district in Queensland, Australia. The specific name ''dawsonensis'' is named for the Dawson River valley where the snail is found. The genus is named after local conservationist Adam Clark. The snail was named by John Stanisic, a scientist at the Queensland Museum. == Distribution == There are currently two known locations of the species, both in the Taroom area. The first is located in three boggomosses on Mt Rose Station (private property), with an estimated population >350, spread over an area of approximately 0.75 ha. Before the surrounding land was cleared for farming these three sites were probably part of the same population group. The second is located in the riparian zone of the Dawson River on a camping and water reserve at the Isla-Delusion crossing approximately halfway between the towns of Taroom and Theodore, with an estimated population of <500 spread over an area of approximately 44.5 ha. It is thought that the species was once more widespread but its range has been greatly reduced by destruction of its preferred habitat. With the revival of the proposal to build the Nathan Dam, one of the environmental concerns was the snails on the Mt Rose Station would be inundated by the dam impoundment. In 2009, a trial project was established to see if these populations could be successfully relocated to other suitable habitats. However, SunWater claimed that further studies revealed populations of 18,000 snails at other unidentified locations outside the inundation area, reducing the concern about the risk of the dam to the snails as a species, allowing the planning of the dam to resume. However, as at August 2015, the Queensland Government still lists the snail as "endangered in Queensland" with only two population groups. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Adclarkia dawsonensis」の詳細全文を読む スポンサード リンク
