2. Evolution of the Neuropeptide Y System in Vertebrates with Focus on Fishes
Abstract : Gene families in vertebrates often contain more dulicates (paralogs) than in invertebrates. This has been attributed to genome duplications, i.e., tetraploidizations. READ MORE

3. Molecular characterization and evolution of alpha-actinin : from protozoa to vertebrates
Abstract : alpha-actinin is a ubiquitous protein found in most eukaryotic organisms. The ability to form dimers allows alpha-actinin to cross-link actin in different structures. In muscle cells alpha-actinin is found at the Z-disk of sarcomeres. READ MORE

4. Geology, stratigraphy, and fossil vertebrates of Gotland, Sweden : a review
Abstract : The Silurian limestones of Gotland, Sweden, and their exceptionally well-preserved fossils have attracted the interest of scientists for more than 200 years. The sedimentary rocks represent approximately 10 million years of time, and were deposited in a shallow, equatorial inland sea named the Baltic Basin. READ MORE

5. Silurian vertebrates of Gotland (Sweden) and the Baltic Basin
Abstract : During the Silurian, the Swedish island Gotland was positioned close to the equator and covered by a shallow sea called the Baltic Basin. The sedimentary rocks (predominantly carbonates) comprising most of the island today were initially formed in this warm sea, and the relatively complete succession of rocks often contains fossil fragments and scales from early vertebrates, including heterostracans, anaspids, thelodonts, osteostracans, acanthodians, and a stem-osteichthyan.
