T. Ryan Gregory, doctoral candidate at the University of Guelph (Canada), provides this comprehensive data catalog of animal genome size. Included on site are haploid genome sizes (C-values) for approximately 2,100 species or subspecies of vertebrates and 800 species of invertebrates. Organized by taxa, this Website-in-progress will be of direct use to those researchers whose study organisms are...

This no-frills UC-Santa Cruz Genome Bioinformatics Web site contains searchable "working drafts of the human genome and the mouse genome," which each represent "immense collaborative efforts" within the biomedical research community. Those who are active in genome research may find this Web site useful, especially for the multi-faceted genome browser that "provides a rapid and reliable display of...

In the deep still of winter many animals are hibernating. What knowledge or inspiration can humans gain from our hibernating kin? The following websites present important and interesting information that people have discovered from studying hibernation. The first site, both comprehensive and well-designed, provides a good overview of hibernation and defines related terms such as torpor,...

This Web site from the journal Nature offers a one-stop online resource for information on the mouse genome -- "the experimental key to the human genome." Visitors have free access to all content from the journal's special mouse genome issue. Web features include an interactive timeline detailing the history of the mouse in genetics, related news articles and commentary, Web links, and more....

The NCBI (National Center for Biotechnology Information) Taxonomy Browser, enables users to search for taxonomic information using the name of superspecific taxa (e.g., Porifera) or the name of a particular organism (e.g., Thalarctos maritimus or polar bear). Returns provide, in addition to taxonomic information, genetic information, nucleotide/protein sequence information, and references.
