  • Planeticovorticella Finleyi N.G., N.Sp. (Peritrichia, Vorticellidae), a Planktonic Ciliate with a Polymorphic Life Cycle
    Invertebrate Biology 119(1): 1-16. © 2000 American Microscopical Society, Inc. Planeticovorticella finleyi n.g., n.sp. (Peritrichia, Vorticellidae), a planktonic ciliate with a polymorphic life cycle John C. Clampl,a and D. Wayne Coats2 1 Department of Biology, North Carolina Central University, Durham, North Carolina 27707 USA 2 Smithsonian Environmental Research Center, PO Box 28, Edgewater, Maryland 21037 USA Abstract. Free-swimming trophonts of a sessiline peritrich ciliate were discovered in plankton samples from the Rhode River, Maryland, and main-stem Chesapeake Bay. Cultures revealed that the species comprises both free trophonts that swim with their peristomial cilia and sessile trophonts that attach to substrates with a contractile, helically-twisted stalk. Trophonts with a short, rigid stalk or no definite stalk also were seen in culture. Binary fission of free-swimming trophonts usually produced a pair of trophonts attached scopula to scopula by a short, rigid stalk. These persisted for some time as distinctive, spinning doublets before their stalks broke and they separated. Binary fission of free-swimming trophonts also yielded trophont-telotroch pairs that stayed together for only a short time. Telotrochs from these pairs were presumably the source of attached trophonts. Conjugation occurred in both free and attached trophonts. Formation of microconjugants involved at least 2 successive divisions of a trophont. Possession of a helically-twisted, contractile stalk placed the peritrich in the family Vorticellidae, but its unique combination of life-cycle stages marks it as a new genus and species, Planeticovorticella finleyi. The morphology and life cycle of P. finleyi raise questions about the present classifi­ cation of sessiline peritrichs and suggest that it may be at least partly artificial.

Larval stages of the sand goby (Pomatoschistus minutus) possess a number of attractive qualities for experimental testing that make it a promising species in behavioural ecotoxicology. Here, we present a study aimed at developing a toolkit for using the sand goby as novel species for ecotoxicological studies and using locomotion as an alternative endpoint in toxicity testing. Exposure to three contaminants (copper (Cu), di-butyl phthalate (DBP) and perfluorooctanoic acid (PFOA) was tested in the early life stages of the sand goby and the locomotion patterns of the larvae were quantified using an automatic tracking system.

    Artificial Sea Water Salts Broth M1942 An artificial salt mixture closely resembling the composition of ocean water, for culturing marine bacteria. Composition** Ingredients Gms / Litre Sodium chloride 24.600 Potassium chloride 0.670 Calcium chloride 2H2O 1.360 Magnesium sulphate 7H2O 6.290 Magnesium chloride 6H2O 4.660 Sodium bicarbonate 0.180 Final pH ( at 25°C) 7.5±0.5 **Formula adjusted, standardized to suit performance parameters Directions Suspend 31.73 grams(the equivalent weight of dehydrated medium per litre) in 1000 ml distilled water.If desired filter through whatmann filter paper. Dispense as desired and sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Principle And Interpretation Artificial sea water is primarily used in marine biology and allows the easy preparation of media appropriate for marine organisms. Marine artificial media are used when critical studies cannot be conducted using a natural seawater base,so artificial seawater medium is used to minimize or exclude known contaminants for the purpose of studying trace elements.The Artificial sea water recipe consists of mineral salts, some anhydrous salts that can be weighed out, and some hydrous salts that should be added to the artificial seawater as a solution(1). There are many formulas, each with its own characteristics. The quality of a brand of sea salt is dependent on the formula, the quality of the raw materials and the uniformity of the blending. The salinity is the sum of all of the dissolved ions(2). All the salts present in the medium provides organic source of growth nutrients. Vibrio and Halobacteriumie are commom survivals,under conditions of hyper osmolarity.
