Book excerpt: Excerpt from Morphology and Biology of Some Turbellaria From the Mississippi Basin: With Three Plates Woodworth (1897) and Stringer (1909, 1913) have published descriptions Of five new species from Illinois and Nebraska. Eleven other forms, found also in the eastern states, have been reported from a few localities in Illinois, Neb raska, Michigan, and Wisconsin, but these are all. That some species, at least, are present in great numbers is evident from the various collections for experimental studies. The whole Mississippi valley region with its lakes and almost numberless ponds furnishes conditions in many respects ideal for such types, and their existence will sooner or later be demonstrated. In fact, both Planaria and Rhabdocoelida are of much more common occur rence than is generally supposed and for several reasons are especially valuable for study. First, they are available as living reproducing animals thruout the year. Then, they are good for experimental work since they illustrate a some what primitive phylum, one in which the body structure is very different from that commonly encountered. Well adapted to such studies by their simplicity and great vitality, they have come to be the classic specimens employed both for elementary experiment and for complicated investigation. The free-living method of life, together with the simple fundamental anatomy, when compared with the specialized and much changed condition of the nearly related parasitic worms, shows clearly the variations possible and actually brought about by a different mode Of life. As a whole, the group is of more than ordinary interest. Always considered of no importance economically, their possible relation to other forms has been overlooked, so that only by chance have their habits Of parasitism and voracious feeding been discovered, and there is need Of further investigation along this line.

Download or read book Biology of Turbellaria and some Related Flatworms written by Lester R.G. Cannon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbellaria, the mainly free-living flatworms, and some of their parasitic relatives, are among the simplest of the metazoa and, as such, provide ideal models for a wide range of fundamental studies. The 60 contributions to Biology of Turbellaria and some Related Flatworms cover taxonomy and phylogeny, biogeography and genetics, ecology and behaviour, Anatomy and ultrastructure, development and regeneration, genes and sequences, and neurophysiology. Biology of Turbellaria and some Related Flatworms is the most recent compilation in the series published in Hydrobiologia since 1981, covering research on these flatworms assembled by the world's leading authorities on the group. Audience: These papers present the advanced student and serious researcher with up to date information on an important, but often neglected group whose place in the animal kingdom demands greater attention.

Book excerpt: Turbellarian platyhelminths (or, as they are known now among cladistic systematists, free-living Platyhelminthes) comprise a widely distributed assemblage of lower worms found in marine, freshwater, and even occasionally in terrestrial habitats. The phylum Platyhelminthes may be more widely known for its parasitic members since the major parasitic groups of the tapeworms, flukes, and their relatives are more speciose and have greater impact on everyday human life; but the turbellarians are more diverse and, as inhabitants of virtually any aquatic habitat, are more widespread as well. Many of the lower turbellarians are rather simple in morphology and have served as models for ancestors of the Bilateria, i.e., the bulk of the animal phyla. Others are quite complex organisms, especially in the morphology of their reproductive systems which are highly specialized. The majority are free-living in aquatic habitats but a number of interesting parasitic and commensal species are found scattered among the higher turbellarian taxa. But turbellarians are more than just taxonomic curiosities. They have served as illustrative models in research on a variety of basic life processes. For example, their high capacity for regeneration has made them the subject of a large literature in developmental biology, the occurrence of mixoploidy and other karyological oddities among turbellarians has been important in understanding evolution of the genome, and the fine structure and biochemistry of the nervous system in turbellarians is revealing important principles of the organization of so-called primitive neural systems.
