Management and conservation actions in marine-protected areas require baselines for monitoring threatened marine fauna such as elasmobranchs. This article provides evidence of the occurrence of 34 species of elasmobranchs (21 sharks and 13 batoids) in the Malpelo Flora and Fauna Sanctuary, Colombia, including five new records of sharks and three of rays. From 1987 to 2021, new records were obtained by underwater visual census using SCUBA, manned submersibles and deep-ocean cameras to depths of up to 2211 m. Of the recorded species, 21 are considered as threatened taxa (64%) by the IUCN, making the Malpelo Flora and Fauna Sanctuary an essential conservation area for this highly threatened group of species.  相似文献

中国华夏植物区科达植物的研究历史虽然最早可上溯至1883年,但直到1991年才首次报道其角质层构造.到目前为止,中国华夏植物区总共描述了4种科达植物原位角质层和3种分散角质层.但与欧美植物区相比,有关中国华夏植物区科达植物角质层的研究工作还较薄弱.本文较详细地描述了3种产自中国华夏植物区二叠纪煤系地层中的科达植物分散角质层.其中2种采自华北亚区南缘的安徽淮南新庄孜矿山西组A1煤顶板,地质时代为早二叠世;另一种采自华南亚区的贵州水城矿区大河边矿龙潭组顶部的11号煤层,地质时代为晚二叠世早期.将这3种科达植物分散角质层与已知的欧美植物区和中国华夏植物区的种类进行了对比,认为它们都是新的类型.讨论了这3种新的科达植物分散角质层所具有的古植物学意义.  相似文献

A robust Laboratory Information Management System (LIMS) is required for the efficient handling of data generated from large-scale insertional mutagenesis projects. The Rice Gene Machine Information Management System (RGMIMS), a web-based modular LIMS, developed in a rice functional genomics laboratory at CSIRO, currently has four core modules: Seed Management, Transformation Management, Plant/Progeny Management, Phenotype Management, and an ad hoc querying module. RGMIMS manages, preserves and tracks large inventories of transgenic germplasm and enables efficient and accurate record keeping of the large quantities of experimental data. RGMIMS automates and seamlessly integrates multi-step experimental processes. A web user interface, incorporating barcoding utilities, enables rapid data capture and tracking of biological resources. Ontologies from Gramene and Plant Ontology consortium are used to describe mutant phenotypes. RGMIMS supports generic research processes in plant mutagenesis and could readily be adapted to general LIMS for high-throughput plant research.  相似文献

The Flora North America Program will create a computer data bank of taxonomic information about the vascular plants of North America north of Mexico. The system, which will serve a broad range of users, will provide for the acquisition, editing, and storage of data and the preparation of a variety of products. It will grow and evolve over a long period of time, continually incorporating changes to data and new categories of information as they become available. The system will utilize an existing computer program package, the IBM Generalized Information System (GIS), for creating, maintaining, querying, and generating reports from its files of data. In addition to a file of taxonomic, ecological, and geographic data about each taxon, the system will build and maintain a series of authority or dictionary files to control system content. The first major system product will be a published flora, generated by computer. Many other catalogs and indexes will be prepared and specific questions may be asked of the data bank to meet individual user needs for information.  相似文献
