ZO 402 Invertebrate Zoology Enrolled students and instructor-authorized guests have access to the syllabus, etc., by this link. (revised 4/7/03) (revised 4/7/03) Links to Web Pages for Invertebrate Phylogeny This site not only has exhibits and articles on paleontology, but also on the phylogeny and classification of living things, including animals. This is a summary of the phylogeny of the higher taxa of living things. Recently, some of the phylogenies have been removed pending incorporation of recent findings. In the interim, it offers the simplified, traditional, and now widely thought to be incorrect phylogenies of invertebrates proposed in the textbook by Brusca and Brusca from about 1990. Provided by University of Maine; many links are defunct. This is an excellent, in-depth introduction to animal phylogeny.
It is a long article with many illustrations. This is a 'Field Guide' which contains about 100 color photographs made on the sea bottom or in the plankton of larger invertebrates of the Antarctic oceans. While crabs and cephalopods are sparse, there are many, wonderfully bizarre sponges, isopods, polychaetes, and gastropods. The accompanying text discusses the sizes, feeding niches, depth and geographical distribution, and general diversity of the animals.
Maintained by the University of Manchester (England) for teaching. Pbd partition bad disk crack windows 10. Discusses basic characteristics and phylogenetic relationships of many invertebrate phyla and classes. I do not endorse their 'best estimation summary,' a strange kingdom phylogeny of animals included on their 'Relationships' page. Includes other links, summaries and diagrams from recent research papers on several issues in the phylogeny of lower invertebrates. Louise Bush and Seth Tyler of the University of Maine have p[roposed a complete classification of free-living flatworm species, often with illustrations gleaned from obscure publications or unpublished files.
This is a general discussion, with links to source papers that are often in English. Near the bottom of the page, it links to a picture of Ehler's 1985 phylogeny of Platyhelminthes, still widely but not universally accepted This article is partly in response to a letter from Tyler (see link ' Taxonomy of Turbellaria' above), Rieger and Smith criticizing a 1999 Science article by Ruiz-Trillo, et al., that proposed a major revision of lower invertebrate phylogeny. This is a PowerPoint slide talk with a good explanation of the syncytial (British spelling syncitial) epidermis and great scanning EM images of the epidermis of adult tapeworms. It cites a 2001 reference for a Platyhelminthes phylogeny in the early slides. Compare to notes for 2/10/03. We normally think of polychaetes as free-living, but many dozens of species live in close, even obligate relationships with other marine organisms.
This page links to a downloadable, Adobe Acrobat ',pdf' document, a preprint of a published review paper with numerous illustrations and links. Maintaind by Richard Howey of Wyoming, this is a chatty tale of his surprised recognition of Trichoplax, the only genus in the phylum Placozoa, in mixed marine material that he was scanning for protozoans.
Includes links to other sources and a good deal about the biology and ecology of Trichoplax. A good complement to the link immediately above.
An illustrated explanation of its distinguishing characteristics, the importance of its discovery, and the ecology of Symbion pandora, the first known cycliophoran. It is ectocommensal on lobster antennae!
