Catalogue of Life

Catalogue of Life
The Dynamic Edition is a constantly evolving version of the Catalogue of Life. Anything can change as the list develops: names, their associated details, and their content providers and there is no tracking of those changes. For that reason, the Dynamic Edition is not the one to quote if you wish to cite a verifiable source. It is, however, a great 'expert system', helping those at the forefront of their science to track, and contribute to the development of taxonomy. Periodic issues are progressively enhanced, in what will evolve as a dynamically developing system, made available online and as web-services. The Annual Checklist is a snapshot of the entire Catalogue of Life: a fixed imprint.

"The World Tree of Consciousness." Perhaps one of the best known representative of the concept of the World Tree is the Yggdrasil of ancient Norse lore. We still know a great deal about this concept, because unlike most other ancient lore, it persisted until some time after writing was developed by the Norse people. We therefore have access to written records that describe the Yggdrasil and relate to the myths and legends that surround it. The main body of these writings is contained in the Prose Edda of Snorri Sturluson (c.1179-1241), an Icelandic historian who is considered the most accurate editor, redactor and interpreter of old Norse mythology. In the legend the Yggdrasil is composed of nine words, of which Midgardhr, which represents the world in which we live, is the central one. The eight other nonphysical worlds are arranged above, below, east, west, north and south of Midgardhr, and are supported by the trunk and the branches of Yggdrasil.

Molecular Expressions Microscopy Primer: Introduction to Microscopy Introduction to Optical Microscopy,Digital Imaging, and Photomicrography This treatise on optical microscopy is divided into several sections that are available through the links displayed immediately to the left (in the darker navigational boxes) and below. In order to print the entire microscopy primer as a paper document, you must download each link independently, send the file to your printer, and put the results together. In the Bibliography, we have included links to other works on optical microscopy and our section on Web Resources contains links to other microscopy sites on the Internet.

Home The Green Algae Tree of Life (GrAToL) is a project involving the collaboration of five institutions to understand the evolutionary relationships of all of the major groups of green algae, a diverse group of more than 14,000 photosynthetic species worldwide. Green algae are abundant and play important roles in a wide variety of terrestrial and aquatic habitats, including deserts, extremely salty ponds, and coral reefs, and several species are symbiotic partners with lichens and animals. Thus, green algae are important primary producers in most ecosystems. Green algae are diverse in form - from microscopic single cells to large seaweeds - and function as important primary producers in most ecosystems.

A New Thermodynamics Theory of the Origin of Life Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity.

Work on this piece started on January 2012. efloraofindia efloraofindia (eFI in short) website is documenting flora of India that is being discussed on efloraofindia google e-group along with supplementing the working of the group. It has the largest database on net on Indian Flora with more than 10,000 species (along with more than 2,00,000 pictures, from some of the best Flora Photographers of India, at its efloraofindia e-group links). It also includes some species from around the world, which has been posted by our members.
