We consider the problem of counting the interior edge crossings when a bipartite graph G = (V,E) with node set V and edge set E is drawn such that the nodes of the two shores of the bipartition are drawn as distinct points on two parallel lines and…
-
Phylogenetic trees are an important tool for representing evolutionary relationships among organisms. In a phylogram or chronogram, the ordering of taxa is not considered meaningful, since complete topological information is given by the branching…
-
Here we introduce a novel quantitative technique for visualizing hierarchically organized data in a geographic context. In contrast to existing techniques, our visualization emphasizes the hierarchical relationships in the data by depicting them in…

SUMMARY: Many genomic and proteomic analyses generate as a result a tree of genes or proteins. These trees are often large (containing tens of thousands of nodes and edges), and need a visualization tool to fully display all the information…
-
Wild birds are known to carry all strains of influenza and, in theory, any of these strains could be the source of the next human pandemic. Most influenza infections in humans since 1968 have been attributed to influenza A, antigenic subtypes H3N2…
-
Structural comparison of large trees is a difficult task that is only partially supported by current visualization techniques, which are mainly designed for browsing. We present TreeJuxtaposer, a system designed to support the comparison task for…
-
MOTIVATION: Despite substantial efforts to develop and populate the back-ends of biological databases, front-ends to these systems often rely on taxonomic expertise. This research applies techniques from human-computer interaction research to the…
-
MOTIVATION: Bayesian analysis through programs like BEAST (Drummond and Rumbaut, 2007) and MrBayes (Huelsenbeck et al., 2001) provides a powerful method for reconstruction of evolutionary relationships. One of the benefits of Bayesian methods is…
-
Common existing phylogenetic tree visualisation tools are not able to display readable trees with more than a few thousand nodes. These existing methodologies are based in two dimensional space.
-
Paloverde is a new program designed to help visualize the phylogenetic structure of moderately large trees--trees on the scale of 100-2500 leaf nodes. The program embeds the user in an interactive virtual 3D world in which a large tree presented in…
-
The extensive data set of evolutionary relationships between organisms is often referred to as the Tree of Life. Providing an effective visual interface for teachers and students to interact with this data set requires bringing together work from…
-
The purpose of this application, under Article 70.2 of the Code, is to conserve the current usage of the widely used name Drosophila Fallén, 1832 (a genus of flies widely used in biological research, particularly in genetics and developmental…

An application to conserve the current usage of the widely used name Drosophila Fallén, 1823 (a genus of flies widely used in biological research, particularly in genetics and developmental biology) in the face of potential taxonomic revision, by the…

Iorania concordia gen. nov., sp. nov. (Crustacea: Decapoda) belonging to the family Alvinocarididae is described from the Mid Atlantic Ridge, TAG location (26°09'N 44°50'W). The taxonomic position in the family and distinguishing characters…
-
Independent species descriptions of a "small orange" caridean shrimp found at deep-sea hydrothermal vents along the Mid-Atlantic Ridge have created the synonymous names Iorania concordia Vereshchaka 1996b and Rimicaris aurantiaca Martin et al. 1997.…
-
We constructed a corpus of digitized texts containing about 4% of all books ever printed. Analysis of this corpus enables us to investigate cultural trends quantitatively. We survey the vast terrain of 'culturomics,' focusing on linguistic and…
-
We found that trends in the rate of description of 580,000 marine and terrestrial species, in the taxonomically authoritative World Register of Marine Species and Catalogue of Life databases, were similar until the 1950's. Since then the relative…

The diversity of life is one of the most striking aspects of our planet; hence knowing how many species inhabit Earth is among the most fundamental questions in science. Yet the answer to this question remains enigmatic, as efforts to sample the…
