A Collaborative Effort between the California Biodiversity Council and the University of California at Davis Information Center for the Environment. The signatories of the California Biodiversity Council joined forces to gather information on thousands of conservation, mitigation and restoration projects being developed and implemented throughout California. The result, the Natural Resource Project Inventory (NRPI), has become a comprehensive electronic database searchable on the Internet. NRPI is an expansion of previous inventories including 1) the Watershed Projects Inventory (WPI), 2) the California Ecological Restoration Projects Inventory (CERPI), and 3) the California Noxious Weed Control Projects Inventory.

The NRDB is a compilation of observations of flora and fauna made at open space and nature preserves in the greater San Francisco Bay Area. The database can be searched for available data on flora, mammals, birds, and reptiles-amphibians-fishes seen at one or more preserves.

Primate Info Net (PIN) is designed to cover the broad field of primatology providing original content and links to resources about nonhuman primates in research, education and conservation.

The Carcinogenic Potency Database (CPDB) is a unique and widely used international resource of results from 6153 chronic, long-term animal cancer tests on 1485 chemicals. CPDB provides a standardized and easily accessible database with qualitative and quantitative analyses of both positive and negative experiments that have been published in the general literature through 1997 and by the National Cancer Institute/National Toxicology Program through 1998. This Web site is designed to facilitate use of the CPDB by presenting the information in summary tables as well as in the detailed plots that have been published.

This document provides synopses of frequently used time series of global-change data, particularly records of atmospheric chemistry including carbon dioxide, methane, carbon isotopes, carbon flux, cloud cover, temperature, and ecosystems. Data records are presented in multipage formats, each dealing with a specific site, region, or emissions species. The data records include tables; graphs; discussions of methods for collecting, measuring, and reporting the data; trends in the data, and references to literature providing further information. Trends online is hosted by the Carbon Dioxide Information Analysis Center of the U.S. Department of Energy.

The World Data Center for Paleoclimatology provides data about past climate and environment derived from a diverse range of proxies such as tree rings and ice cores. The proxies are listed by data disciplines. These links provide access to descriptive information and explanatory notes, links to maps, searches, visualizations, and more. The data cover the globe, and while most span the last few millennia, some data sets extend back in time 100 million years. Most of the data are time series of geophysical or biological measurements, and some include reconstructed climate variables such as temperature and precipitation. We have highlighted most of the climate reconstruction data sets in an annotated list. For non-specialists seeking climate data, this list is a useful starting point. Maps and visualizations exist for some data sets. Almost all of the data have been contributed by scientists who have published their results in peer-reviewed literature. The data are used by researchers to understand climate variability, by educators and students and curious individuals to study the past, and by planners and decision-makers who need a better understanding of long-term changes to make policy decisions.

GEO serves as a public repository for a wide range of high-throughput experimental data. These data include single and dual channel microarray-based experiments measuring mRNA, genomic DNA, and protein abundance, as well as non-array techniques such as serial analysis of gene expression (SAGE), and mass spectrometry proteomic data.

ChemBank is a public, web-based informatics environment created by the Broad Institute's Chemical Biology Program and funded in large part by the National Cancer Institute's Initiative for Chemical Genetics (ICG). This knowledge environment includes freely available data derived from small molecules and small-molecule screens, and resources for studying the data so that biological and medical insights can be gained. ChemBank is intended to guide chemists synthesizing novel compounds or libraries, to assist biologists searching for small molecules that perturb specific biological pathways, and to catalyze the process by which drug hunters discover new and effective medicines.

The MorphoBrowser database and interface is a 3D visualisation and searching tool for mammalian teeth, accessible over the web. It allows the user to browse through the diverse range of tooth morphologies found in mammals, both extinct and extant. While browsing, the three-dimensional shape of the teeth can be viewed from any direction by rotating and scaling the tooth.

The NOW (Neogene of the Old World) database contains information about Eurasian Miocene to Pleistocene land mammal taxa and localities, with emphasis on the European Miocene and Pliocene. The NOW database is maintained and coordinated at the University of Helsinki by Mikael Fortelius in collaboration with an international advisory board.

BMRB's mission is to collect, archive, and disseminate (worldwide in the public domain) the important quantitative data derived from NMR spectroscopic investigations of biological macromolecules. Relevant data are deposited by the scientists who generate them, and in consultation with these scientists, BMRB resolves any problems with the self-consistency and completeness of the deposition. In collaboration with the Protein Data Bank, BMRB provides links between the spectral data and associated atomic coordinates. BMRB works with the user community to develop formats for these data that can be parsed by computers and used for knowledge generation, alone and in conjunction with information from other databases. BMRB's goal is to empower scientists in their analysis of the structure, dynamics, and chemistry of biological systems and to support further development of the field of biomolecular NMR spectroscopy.

The internet Primate Aging Database (iPAD) is a multi-centered, relational database of biological variables in aging, captive nonhuman primates. Through joint initiative of the National Institute on Aging (intramural and extramural programs), National Center for Research Resources (NCRR), and the National Primate Research Center at the University of Wisconsin-Madison (WNPRC), we have organized a database to study biomarkers of aging in nonhuman primates. iPAD also provides an invaluable veterinary and clinical resource, and can generate normative data for numbers of animals across research settings. iPAD now contains over 400,000 data points for body weight, blood chemistry and hematology, for healthy, non-experimental subjects across time.

Metazome is a database and graphical user interface enabling comparative genomic studies within the Metazoa. As of version 1.1, the database houses eleven sequenced animal genomes and is constantly growing as new genomes become available. Each gene has been annotated with PFAM, KOG, and PANTHER assignments, and publicly available annotations from RefSeq, SwissProt, Ensembl, and JGI are hyper-linked and searchable. For comparative studies, various clustering methods have been applied to construct orthologous groups of genes that represent the modern descendents of ancestral gene sets at key phylogenetic nodes, including the ancestral tetrapod and vertebrate. These clusterings allow easy access to clade specific orthology/paralogy relationships as well as clade specific genes and gene expansions. Position specific profiles will be made available shortly and gene phylogenetic trees are available now for each cluster to enable deeper comparative studies. The website is supported by the DOE Joint Genome Institute and the Center for Integrative Genomics at UC Berkeley.

A challenge facing researchers today is that of piecing together and analyzing the plethora of data currently being generated through the Human Genome Project and scores of smaller projects.
