The study shows that species that often occur together now are projected
to shift in very different ways, resulting in new ecological communities.
These novel (or "no-analog") communities may disrupt complex webs of plant
and animal interactions, with unanticipated consequences for species and
ecosystems.
The NBII Northeast Information Node (NIN) Web site gives users-educators, resource managers, researchers, and the general public-easy access to the data resources and analysis tools they need to better understand, utilize, and protect the environmental resources of this region.
The National Biological Information Infrastructure (NBII) is a broad, collaborative program to provide increased access to data and information on the nation's biological resources. The NBII links diverse, high-quality biological databases, information products, and analytical tools
The Species 2000 & ITIS Catalogue of Life is planned to become a comprehensive catalogue of all known species of organisms on Earth. Rapid progress has been made recently and this, the ninth edition of the Annual Checklist, contains 1,160,711 species. Please note that this is probably just more than half of the world's known species. This means that for many groups it continues to be deficient, and users will notice that many species are still missing from the Catalogue.
The present Catalogue is compiled with sectors provided by 66 taxonomic databases from around the world. Many of these contain taxonomic data and opinions from extensive networks of specialists, so that the complete work contains contributions from more than 3,000 specialists from throughout the taxonomic profession. Species 2000 and ITIS teams peer review databases, select appropriate sectors and integrate the sectors into a single coherent catalogue with a single hierarchical classification. It is planned to introduce alternative taxonomic treatments and alternative classifications, but an important feature is that for those users who wish to use it, a single preferred catalogue, based on peer reviews, will continue to be provided.
