Loricifera Acknowledgements Glossary Bibliography Biographical Sketch Summary UNESCO – EOLSS This chapter provides information on several basal bilaterian groups: flatworms, nemerteans, Gnathifera,SAMPLE and Nemathelminthes. CHAPTERS These include species-rich taxa such as Nematoda and Platyhelminthes, and as taxa with few or even only one species, such as Micrognathozoa (Limnognathia maerski) and Cycliophora (Symbion pandora). All Acanthocephala and subgroups of Platyhelminthes and Nematoda, are parasites that often exhibit complex life cycles. Most of the taxa described are marine, but some have also invaded freshwater or the terrestrial environment. “Aschelminthes” are not a natural group, instead, two taxa have been recognized that were earlier summarized under this name. Gnathifera include taxa with a conspicuous jaw apparatus such as Gnathostomulida, Micrognathozoa, and Rotifera. Although they do not possess a jaw apparatus, Acanthocephala also belong to Gnathifera due to their epidermal structure. ©Encyclopedia of Life Support Systems (EOLSS) BIOLOGICAL SCIENCE FUNDAMENTALS AND SYSTEMATICS – Vol. -

I FLATWORM PREDATION on JUVENILE FRESHWATER
FLATWORM PREDATION ON JUVENILE FRESHWATER MUSSELS A Thesis Presented to the Graduate College of Southwest Missouri State University In Partial Fulfillment of the Requirements for the Master of Science Degree By Angela Marie Delp July 2002 i FLATWORM PREDATION OF JUVENILE FRESHWATER MUSSELS Biology Department Southwest Missouri State University, July 27, 2002 Master of Science in Biology Angela Marie Delp ABSTRACT Free-living flatworms (Phylum Platyhelminthes, Class Turbellaria) are important predators on small aquatic invertebrates. Macrostomum tuba, a predominantly benthic species, feeds on juvenile freshwater mussels in fish hatcheries and mussel culture facilities. Laboratory experiments were performed to assess the predation rate of M. tuba on newly transformed juveniles of plain pocketbook mussel, Lampsilis cardium. Predation rate at 20 oC in dishes without substrate was 0.26 mussels·worm-1·h-1. Predation rate increased to 0.43 mussels·worm-1·h-1 when a substrate, polyurethane foam, was present. Substrate may have altered behavior of the predator and brought the flatworms in contact with the mussels more often. An alternative prey, the cladoceran Ceriodaphnia reticulata, was eaten at a higher rate than mussels when only one prey type was present, but at a similar rate when both were present. Finally, the effect of flatworm size (0.7- 2.2 mm long) on predation rate on mussels (0.2 mm) was tested. Predation rate increased with predator size. The slope of this relationship decreased with increasing predator size. Predation rate was near zero in 0.7 mm worms. Juvenile mussels grow rapidly and can escape flatworm predation by exceeding the size of these tiny predators. -

The mapping methodology is summarized in Harney et al (2008). This data summary report provides information on geomorphic and biological features of 4,694 km of shoreline mapped for the 2012 survey of Northwest Alaska. The habitat inventory is comprised of 3,469 along-shore segments (units), averaging 1,353 m in length (note that the AK Coast 1:63,360 digital shoreline shows this mapping area encompassing 3,095 km, but mapping data based on better digital shorelines represent the same area with 4,694 km stretching along the coast). Organic/estuary shorelines (such as estuaries) are mapped along 744.4 km (15.9%) of the study area. Bedrock shorelines (Shore Types 1-5) are extremely limited along the shoreline with only 0.2% mapped. Close to half of the shoreline is classified as Tundra (44.3%) with low, vegetated peat the most commonly occurring tundra shore type. Approximately a third (34.1%) of the mapped coastal environment is characterized as sediment-dominated shorelines (Shore Types 21-30). -
