PREMISE OF THE STUDY Recent analyses employing up to five genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses. METHODS We conducted two primary(More)
The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that(More)
Traditionally the Dusun indigenous people of Borneo consider Mt. Kinabalu the home of spirits and ancestors, and they are loath to climb the summit without good cause and plentiful propitiation. In apparent accordance with these beliefs, Projek Etnobotani Kinabalu has recorded few useful plants at high elevations on Mt. Kinabalu. We ask the question: is(More)
More than a billion biological specimens have been collected, preserved, and deposited in the permanent collections of museums and herbaria around the world. These specimens are the foundation of our knowledge about biological diversity, past and present. Researchers in biodiversity informatics are engaged in providing digital access to the basic(More)
November 2006 | Volume 4 | Issue 11 | e381 Over the past 250 years, biologists who were interested in describing and understanding patterns of biological diversity have gone into the fi eld to observe and collect species. Conservation of the specimens and data collected through these explorations has produced an irreplaceable archive of life on Earth [1].(More)
New information technologies have enabled the scientific collections community and its stakeholders to adapt, adopt, and leverage novel approaches for a nearly 300 years old scientific discipline. Now, few can credibly question the transformational impact of technology on efforts to digitize scientific collections, as IT now reaches into almost every nook(More)

Increasing the quantity and quality of data is a key goal of biodiversity informatics, leading to increased fitness for use in scientific research and beyond. This goal is impeded by a legacy of geographic locality descriptions associated with biodiversity records that are often heterogeneous and not in a map-ready format. The biodiversity informatics(More)
Tillandsia subg.Pseudalcantarea (Bromeliaceae) includes four species as currently delimited. The phylogenetic relationships of the species in this group are investigated by a cladistic analysis using 16 morphological characters, withVriesea subg.Alcantarea employed as the outgroup.Tillandsia subg.Pseudalcantarea is found to be paraphyletic.Tillandsia(More)
The development of biological informatics infrastructure capable of supporting growing data management and analysis environments is an increasing need within the systematics biology community. Although significant progress has been made in recent years on developing new algorithms and tools for analyzing and visualizing large phylogenetic data and trees,(More)
