Wiley is a global provider of content and content-enabled workflow solutions in areas of scientific, technical, medical, and scholarly research professional development and education. The Division of Invertebrate Zoology of the Society for Integrative and Comparative Biology joins with AMS in promoting the journal, which is co-published with Blackwell Publishing. For 100 years (1895-1995) the title was Transactions of the American Microscopical Society it has since been published under the title Invertebrate Biology to reflect its current broad scope on the biology of invertebrate animals. The journal, published by the American Microscopical Society (AMS), ranks among the oldest continuously published journals in the United States, having been in existence since 1880. All contributions undergo a thorough process of peer-review. Invertebrate Biology (IB) presents original research and review papers on all aspects of invertebrate biology-morphology and ultrastructure genetics, phylogenetics, and evolution physiology and ecology neurobiology, behavior, and biomechanics reproduction and development cell and molecular biology-and on all types of invertebrates: protozoan and metazoan, aquatic and terrestrial, free-living and symbiotic. ![]() These studies suggest testable hypotheses on the molecular mechanisms underlying alternate developmental trajectories, and they provoke new questions about the evolution of novel developmental trajectories and their initiation via environmental cues. Additionally, we describe the predictable generation of anomalous phenotypes that can occur following localized injuries to the body column. Here, we compare the ontogenetic sequences underlying alternate developmental trajectories. vectensis may arise via four distinct developmental trajectories: (1) embryogenesis following sexual reproduction, (2) asexual reproduction via physal pinching, (3) asexual reproduction via polarity reversal, and (4) regeneration following bisection through the body column. vectensis have provided important insights into the evolution of key metazoan traits. ![]() Molecular studies of embryology and larval development in N. In recent years, this anemone has emerged as a model system in cnidarian developmental biology. The starlet sea anemone, Nematostella vectensis, is a small burrowing estuarine animal, native to the Atlantic coast of North America.
