A close relationship between ectoprocts, bryozoans, and cycliophorans was originally suggested by Funch and Kristensen after the first description of a cycliophoran, Symbion pandora. These authors pointed out that cycliophorans, entoprocts, and bryozoans have some similarities in the development of feeding structures and asexual budding.Bryozoan polymorphism refers to occurrence of multiple body types of zooids that may occur within a single colony. Determining the origin and evolution of polymorphism is challenging because zooid budding is clonal so that different polymorphs are genetically identical. As with brooding, it is unknown how many convergent origins of similar ...At least 3,500 living species and 15,000 fossil species are known. Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies. In fact, the Phylum Bryozoa is the only animal phylum in which all known species form colonies. The name comes from two Greek words, bryon (moss) and zoon (animal ...

A mycorrhiza (from Greek μύκης mýkēs, "fungus", and ῥίζα rhiza, "root"; PL: mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry.Plasmodium: Plasmodium is a genus of parasite that can infect insects, birds, reptiles and humans. There are a few types of Plasmodium that can cause malaria in humans. Mosquitoes can become infected with these types of Plasmodium.If an infected mosquito then bites a person, it can transmit the parasite to the person and eventually cause malaria.Mississippian limestones in Illinois are generally pure carbonate with little shale or sand and often have caves systems in them. The fossil fauna is highlighted by abundant and diverse crinoids and brachiopods, plus corals, bryozoans, including Archimedes (corkscrew bryozoan), molluscs, sharks, and fish, but trilobites are rare.
