  • 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.

  • Cumulated Bibliography of Biographies of Ocean Scientists Deborah Day, Scripps Institution of Oceanography Archives Revised December 3, 2001
    Cumulated Bibliography of Biographies of Ocean Scientists Deborah Day, Scripps Institution of Oceanography Archives Revised December 3, 2001. Preface This bibliography attempts to list all substantial autobiographies, biographies, festschrifts and obituaries of prominent oceanographers, marine biologists, fisheries scientists, and other scientists who worked in the marine environment published in journals and books after 1922, the publication date of Herdman’s Founders of Oceanography. The bibliography does not include newspaper obituaries, government documents, or citations to brief entries in general biographical sources. Items are listed alphabetically by author, and then chronologically by date of publication under a legend that includes the full name of the individual, his/her date of birth in European style(day, month in roman numeral, year), followed by his/her place of birth, then his date of death and place of death. Entries are in author-editor style following the Chicago Manual of Style (Chicago and London: University of Chicago Press, 14th ed., 1993). Citations are annotated to list the language if it is not obvious from the text. Annotations will also indicate if the citation includes a list of the scientist’s papers, if there is a relationship between the author of the citation and the scientist, or if the citation is written for a particular audience. This bibliography of biographies of scientists of the sea is based on Jacqueline Carpine-Lancre’s bibliography of biographies first published annually beginning with issue 4 of the History of Oceanography Newsletter (September 1992). It was supplemented by a bibliography maintained by Eric L. Mills and citations in the biographical files of the Archives of the Scripps Institution of Oceanography, UCSD.

Hyman Memorial Scholarship • Message from the Graduate Student−Postdoctoral Affairs Committee Representative • Message from the Student Awards Committee Chair • DIZ Auction Message from the Chair Thomas Wolcott I hope that all of you had a summer that was productive, or pleasant, or both, and that you're looking forward to exciting meetings in New Orleans after the turn of the year. I recognize that travel may be more difficult in these times of floundering economies (Isabel came as quite a blow to ours), but hope that you too feel the SICB meetings are worth the investment. Given all the recent news of flooding in eastern NC, some of you may be concerned that we'll be meeting below sea level in New Orleans. Let me reassure you: the clout of the DIZ Chair's office is such that I've been able to extract a firm commitment from the meteorologists: "No hurricane landfalls during the SICB meetings." Division of Invertebrate Zoology (DIZ): 2003 Fall Newsletter 1 Relieved of the hurricane threat, we'll be able to turn our attention to the panoply of contributed paper and poster sessions, as well as the traditional smorgasbord of cutting−edge symposia. In that context, I'm delighted to report that DIZ Program Officer Penny Barnes has been peppered with proposals for future symposia. Let me emphasize that these are not dregs extracted by inverting the barrel and beating on the bottom; these are really interesting topics volunteered by the membership.

Abstract The epidermis is essential for animal survival, providing both a protective barrier and cellular sensor to external environments. The generally conserved embryonic origin of the epidermis, but the broad morphological and functional diversity of this organ across animals is puzzling. We define the transcriptional regulators underlying epidermal lineage differentiation in the planarian Schmidtea mediterranea, an invertebrate organism that, unlike fruitflies and nematodes, continuously replaces its epidermal cells.

  • Introduction to the Bilateria and the Phylum Xenacoelomorpha Triploblasty and Bilateral Symmetry Provide New Avenues for Animal Radiation
    CHAPTER 9 Introduction to the Bilateria and the Phylum Xenacoelomorpha Triploblasty and Bilateral Symmetry Provide New Avenues for Animal Radiation long the evolutionary path from prokaryotes to modern animals, three key innovations led to greatly expanded biological diversification: (1) the evolution of the eukaryote condition, (2) the emergence of the A Metazoa, and (3) the evolution of a third germ layer (triploblasty) and, perhaps simultaneously, bilateral symmetry. We have already discussed the origins of the Eukaryota and the Metazoa, in Chapters 1 and 6, and elsewhere. The invention of a third (middle) germ layer, the true mesoderm, and evolution of a bilateral body plan, opened up vast new avenues for evolutionary expan- sion among animals. We discussed the embryological nature of true mesoderm in Chapter 5, where we learned that the evolution of this inner body layer fa- cilitated greater specialization in tissue formation, including highly specialized organ systems and condensed nervous systems (e.g., central nervous systems). In addition to derivatives of ectoderm (skin and nervous system) and endoderm (gut and its de- Classification of The Animal rivatives), triploblastic animals have mesoder- Kingdom (Metazoa) mal derivatives—which include musculature, the circulatory system, the excretory system, Non-Bilateria* Lophophorata and the somatic portions of the gonads.

Biographical Memoir COPYRIGHT 1991 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. LIBBIE HENRIETTA HYMAN December 6,1888-August 3, 1969 BY LIBBIE H. HYMAN1 AND G. EVELYN HUTCHINSON2 "I WAS BORN IN DES MOINES, Iowa, December 6, 1888, of Jewish parents, both of whom were immigrants to the United States. My father, Joseph Hyman, came from a Polish village, name of Konin, located in a part of Poland that had been appropriated by Russia. It lay within the Russian Pale, where Jews were subject to brutal restrictions. At the age of fourteen he escaped across the border and made his way to London where he lived for some years, earning a living by plying the family trade of tailoring. Eventually he migrated to the United States, where he struck up a strong friendship with one David Goldman. The two men decided to migrate to what was then the far west (namely Iowa) and went to Des Moines, where they built a store, occupying the ground story with a clothing business. "My mother, Sabina or Bena Neumann, was born in Stettin, Germany, one of eight children of a father who died young. She migrated to the United States and went directly to Des Moines, because she had a brother living there.

Vertebrate Comparative Anatomy in Undergraduate Curricula 1969-70 KARL E. GOELLNER Coe College Cedar Rapids, lou;a In 1966 I presented a short paper describing some impressions of the status of vertebrate comparative anatomy ( and embryology) in European universi­ ties ( Goellner, 1968). Discussions which followed seemed to suggest that the status of these courses in the United States may be changing, and that a sur­ vey might elicit information on this matter. A basic assumption was implied, namely, that comparative anatomy had, indeed, been a traditional course in college offerings, particularly for zoology majors and for pre-medical and pre-dental students. This paper presents results of a modest survey conducted during the winter of 1969-70. Survey Procedure A simple set of ten questions was sent out to 126 colleges and universities, addressed either to the chairman of the biology or zoology department, or to the instructor of comparative anatomy if his name was known.
