A hypothetical list of biota, or "hypothetical list" for short, is a list of taxa (of plants, animals, fungi etc.) which are not recorded from a given geographical area, but which ''may'' be found there. Such lists are sometimes included by authors of regional biota, partly to demonstrate that the authors have considered and rejected the taxa in question rather than overlooked them, and partly to encourage researchers and others to seek out the taxa in question so that they can be added to the list of the area's biota in future revisions. Taxa may be included for different reasons: * They may be resident close to the region in question, and the region may have habitat which appears suitable * They may be long-distance vagrants with a pattern of occurrence * They may be poorly studied taxa, which the authors feel could be found in the region if appropriate search techniques are used * There may be historical evidence of occurrence which the authors felt was not watertight enough to justify inclusion in a definitive list for the region Ornithological works which have included hypothetical lists include the following: * ''A field guide to the birds of Hawaii and the Tropical Pacific'' by Pratt, Bruner and Berrett * ''Birds of South Asia. The Ripley Guide'' by Rasmussen and Anderton 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「Hypothetical list of biota」の詳細全文を読む スポンサード リンク
