The Rectification and Digitization of the Alcala and Brown Philippine Collection of Amphibians and Reptiles, California Academy of Sciences

加州科学院（CAS）在Alan E. Leviton博士的指导下获得了一笔拨款，用于部分支持一项项目，该项目将对菲律宾有史以来最大的两栖动物和爬行动物标本标本进行校正和数字化。Angel C. Alcala和已故的Walter C. Brown。当数据从原始的实地记录转录到手写的目录分类账时，出现了大量的转录错误。这些数据包含了这些分类账中的错误，后来被输入了科学院爬行动物学系的计算机数据库。因此，这些错误的数据被科学家、学生和土地管理者引用。这个当前nsf支持的项目的目的是审查和纠正当前的数据库条目，以准确地反映原始字段注释中包含的数据。这将通过详细审查和重新输入这些说明中出现的数据来完成。Alcala和Brown的标本相关数据随后将被用于地理参考（在原始位置上添加纬度和经度），以便于计算机化地理信息系统（GIS）使用。此外，原始的野外笔记将被扫描、数字化并编入索引，以存档那些经常写在高酸含量纸上的变质笔记，并允许广泛的互联网访问这一丰富的资源。其他产品将包括菲律宾两栖动物和爬行动物的清单，每个岛屿已知物种的分布清单，以及基于Alcala和Brown收集的许多新物种的注释目录。该项目的结果将使这些两栖动物和爬行动物物种的重要历史记录能够用于生物地理学、生态学、生物多样性、保护规划和栖息地评估的研究，并有助于确定菲律宾群岛物种起源和分布的研究。研究人员、政府机构和土地管理者可以使用精确的位置和微栖息地数据以及数字地图来精确定位Alcala和Brown收集的每个标本的收集位置。数字实地记录也将允许查阅原始数据，这些原始数据所包含的生态信息比计算机化目录所包含的要多。其他从Alcala和Brown获得标本的机构也可以通过互联网访问修正后的数据库，更正和更新他们的记录。菲律宾群岛被认为是“生物多样性热点”，由于栖息地的改变，许多物种受到威胁。通过在互联网上发布校正后的地理位置参考数据和数字化的实地记录，这些数据可供从事自然保育工作的政府和非政府机构使用。Alcala和Brown收集的数据也将用于CAS的新公开展览，以突出菲律宾和东南亚其他地区的生物多样性。

A grant has been awarded to the California Academy of Sciences (CAS) under the direction of Dr. Alan E. Leviton for partial support of a project to correct and digitize locality records for the largest collection of amphibian and reptile specimens ever assembled from the Philippines, this largely through the efforts of Drs. Angel C. Alcala and the late Walter C. Brown. Extensive transcription errors were introduced when the data were transcribed from original field notes to the handwritten catalog ledgers. The data, containing errors from these ledgers, were later entered into the Academy's Department of Herpetology's computerized database. Consequently, these erroneous data have been referenced by scientists, students, and land managers. The purpose of this current NSF-supported project is to review and correct the current database entries to reflect accurately the data contained in the original field notes. This will be done by detailed review and re-entry of the data as they appear in the those notes. The Alcala and Brown specimen-associated data will then be georeferenced (adding latitude and longitude to the original locality) so that they can then be used by computerized geographic information systems (GIS). In addition, the original field notes will be scanned, digitized, and indexed to archive the deteriorating notes, which were most often written on high-acid-content paper, and allow broad Internet access to this rich resource. Other products will include a checklist to the amphibians and reptiles of the Philippines, a distributional checklist of known species from each island, and an annotated catalog of the many new species that are based on the Alcala and Brown collections. The results of the project will allow these important historic records of amphibian and reptile species to be used in studies of biogeography, ecology, biodiversity, conservation planning and habitat assessments, and aid in studies to determine the origin and dispersal of species within the Philippine Archipelago. Researchers, government agencies, and land managers can use the accurate locality and microhabitat data with digital maps to pin-point where each specimen in the Alcala and Brown collection was collected. The digital field notes will also allow access to the original data, which contain more ecological information than incorporated in the computerized catalog. Internet access to the corrected database will allow other institutions, which obtained specimens from Alcala and Brown, to correct and update their records. The Philippine Islands are considered a "biodiversity hotspot" and numerous species are threatened because of habitat alteration. By posting the corrected and georeferenced data and digitized field notes on the Internet these data can be utilized by government and non-government agencies working on conservation efforts. Data from the Alcala and Brown collection will also be used in new public exhibits at CAS to highlight the biodiversity of the Philippines and other areas of southeastern Asia.
