    Notes: . Paulinella indentata n. sp. is described from benthic sandy sediments of Kames Bay, Scotland. The description is based on light and scanning electron microscopical observations. This marine, testate amoeba has filose pseudopodia, sometimes branched, extending up to 50 μm from the aperture. Tests are oval in outline (c. 15.8 × 9.8 μm) pale yellow in colour with a short collar. The most important diagnostic feature is the morphology of the surface scales which are arranged in staggered rows. Each cell is covered with around 22 scales (c. 5.7 × 2.9 μm). Scales are rectangular, curved with rounded corners and markedly indented along their median axis. They have a hollow channel running below each ridge and their surface is punctuated with rows of pores. This is the first isolation of Paulinella from benthic marine sediments.

    Notes: . Scanning electron microscopic observations of feeding plasmodia show three characteristic features: 1) extension of multilobed pseudopodia protruding from the leading edge of the plasmodium as it advances onto the surface of a food particle, 2) confluence of the lobes to form a sheath-like pseudopodium attached to the surface of the food particle, and 3) protrusion of small nodules with thin lamellar projections from the leading edge of the plasmodium. Sections through freeze-dried preparations of the feeding plasmodium exhibit a highly convoluted under surface in contact with loosened starch grains that appear to be released by extracellular digestion. the cytoplasm, viewed by transmission electron microscopy, contains branched, internally penetrating canals (ca. 2 μm wide) enclosing engulfed starch grains. Starch grains in the deeper part of the canals are more electron dense and appear to be digested. Micropseudopodia (70-80 nm dia.), projecting from the surface of the canals, protrude toward and into the ingested starch grains. Digestive marker enzyme (acid phosphatase) activity was detected cytochemically in food particles penetrated by micropseu-dopodia indicating a digestive role for these structures not reported previously.

    Notes: . Amoebae cultured from seawater collected at a coastal site near Barbados were largely a lobose amoeba with long tapered subpseudopodia identified as Vexillifera telmathalassa. Vexillifera telmathalassa occurs widely in marine environments and additional information is presented here on its fine structure, salinity tolerance, and feeding behavior toward clarification of its taxonomic characteristics and ecological niche. The amoebae were able to adjust to a gradual decline in salinity from 36‰ to 16‰, but at a salinity of 12‰. They all became immobilized and discoidal. The fine structure showed a centrally located nucleus (2.1 μm) with a prominent nucleolus. The plasma membrane is coated with glycostyles 17 nm long and 14 nm apart, and may be derived from secretory vesicles with similar glycocalyx lining. Bacteria and occasional eukaryotic remains occur in digestive vacuoles or membrane-enclosed spaces. Some vacuoles (2.0–2.5 μm) are filled with scattered masses of digested material and resemble the “glanzkörper” previously identified by light microscopy. In addition to bacterial prey, microflagellates were also ingested in laboratory culture as observed by light microscopy. Vexillifera telmathalassa may be more closely linked trophically to the microbial loop than previously recognized.

    Notes: . Physarum polycephalum is classified presently as a sarcodinid in the class Eumycetozoea. It produces a sclerotial dormant stage consisting of a crustose deposit containing nucleated spherules of cytoplasm enclosed within a honey-comb-like matrix of organic walls. When rehydrated, the sclerotium reverts to a plasmodium: 1) the spherules become increasingly vacuolated, 2) electron-dense granules become dispersed within expanding vacuoles, and 3) pseudopodial extensions develop from the periphery of the spherule cytoplasm, penetrating the fragmenting walls, and making interconnections with surrounding spherules, eventually leading to a fully reticulated plasmodium. Six stages are identified during reversion from sclerotium to plasmodium in laboratory cultures, and their successive appearance was mapped over time. The six stages are: 1) sclerotial stage with crenulated nuclei, 2) cytoplasmic activation with smooth nuclear envelopes, 3) initiation of pseudopodial protrusions, 4) pseudopodial penetration into or across walls, 5) cytoplasmic interconnections among spherules with wall disintegration, and 6) fully formed cytoplasmic network as plasmodium. Cytochrome c oxidase activity, expressed per unit protein content of the homogenate, remains fairly constant throughout the developmental sequence, whereas acid phosphatase activity, expressed per unit protein concentration, is somewhat lower in the sclerotium than in subsequent stages of development after hydration.

    Notes: . Planktonic sarcodines, suspended in the water column, are conveniently grouped into three categories based on functional morphology: (1) gymnamoebae and their relatives, which lack major living or nonliving compartmentalizing barriers, (2) foraminifera, and testate amoebae enclosed by a test or shell with one or more major openings, but lacking extensive cytoplasmic compartmentalizing barriers, and (3) radiolaria, which exhibit distinct compartmentalization of the cytoplasm into functional zones. Differences in feeding strategies and trophic activity of members in the three groups reflect in part these differences in functional morphology. Members of all three groups form symbiotic associations with Monera and protists, including algae, thus partially offsetting interspecific trophic competition among species occupying the same water mass. Physiological and morphological adaptations supporting a symbiotic association are presented. C14-labeling studies of endosymbiotic radiolarian species show a substantial contribution of carbon to the host. Rates of calcification (planktonic foraminfera) and silica deposition (radiolaria) are reported, based on morphometric analyses and isotopic labeling studies. Major distributional patterns in space and time for each of the three groups, and some ecological principles explaining these regularities, are presented as related to population growth dynamics, niche differentiation, water-mass properties, and the role of symbionts in supporting highly diverse communities of species within the same locale in the water column.
