suggest that reticulopodia are self-organizing,and that their instantaneous reticular form is anemergent property continuously recalculatedfrom real-time processing of myriad physiologicaland environmental imputs. Reticulopodialform at any point or region appears to be thesummed behavioral response to these parameters.Our studies indicate that reticulopodial morphologyand behavior can be modified by environmentalstimuli, like substratum adhesivity, andsuggest that processes, such as shell patterning,that depend on pseudopodia could also be modifiedby environmental factors.2008040225有 孔 虫 七 个 种 中 的 伪 足 细 胞 器 官 移 动 的 温 度依 赖 性 和 它 的 相 关 结 果 = Temperature dependenceof pseudopodial organelle transport inseven species of foraminifera and its functionalconsequences. ( 英 文 ). Cedhagen T; FrimansonH. Journal of Foraminiferal Research, 2002,32(4): 434-439 1 图 版 .The rate of transportation of granules (mitochondria)within the pseudopodia was studied inseven sublittoral foraminiferan species from thewest coast of Sweden: Astrorhiza limicola, Cornuspirafoliacea, Crithionina granum, Globipelorhizasublittoralis, Phainogullmia aurata,Quinqueloculina seminulum and Technitellalegumen. The average organelle velocity wasfound to increase with temperature in all species.Five of these species showed a similar increaseof velocity (about 2–4 µm/s at 2°C, to about 6–8µm/s at 17°C). The velocity of Quinqueloculinaseminulum, however, increased far more than theothers at high temperatures (9–12 µm/s at 17°C),while the velocity of the komokiacean Globipelorhizasublittoralis was far less than all othersat all temperatures (about 2 µm/s at 2°C to 4µm/s at 13°C). The increased pseudopodial organellevelocity is interpreted to reflect an increasedmetabolism and consequently an increaseddemand for the exchange of oxygen,waste products, and material through the pseudopodialmembrane. The much branched granuloreticulosepseudo-podial network increases therespiratory surface many-fold. We suggest thatthis is a factor allowing the extreme increase incell size in foraminiferans.2008040226Reticulopodia— 根 据 结 构 和 行 为 基 础 探 讨 粒网 状 原 生 动 物 属 级 以 上 的 分 类 位 置 = Reticulopodia:structural and behavioral basis for thesuprageneric placement of granuloreticulosanprotists. ( 英 文 ). Bowser S S; Travis J L. Journalof Foraminiferal Research, 2002, 32(4): 440-447 3 图 版 .A complex array of branching and anastomosinggranular pseudopodia (reticulopodia) isthought to be a primary feature of the protistanphylum Granuloreticulosa. This essay summarizesthe results of detailed structural and behavioralanalyses of reticulopodia from representativespecies of "naked," "soft-shelled," andunilocular agglutinated Foraminifera. Promiscuousplasma membrane fusion, experimentallydemonstrated here for the first time, togetherwith the presence of tubulin polymorphs and aunique class of ellipsoid vesicles, form a suite ofphenotypic characters that further define the supragenericstatus of these protists. A theoreticalframework for exploring the evolution of reticulopodiais also presented.2008040227澳 大 利 亚 昆 士 兰 州 Moreton 岛 西 海 岸 远 岸 大型 有 孔 虫 Discobotellina biperforata 的 空 间 分布 = Spatial distribution of the large foraminiferanDiscobotellina biperforata, off the westshore of Moreton Island, Queensland, Australia.( 英 文 ). Souter P B; Cedhagen T. Journal of ForaminiferalResearch, 2002, 32(4): 448-452 1 图版 .A hierarchical sampling study of the distributionof the large foraminiferan Discobotellinabiperforata (Collins, 1958) was conducted alongthe west shore of Moreton Island, at Shark Spitand Tangalooma, in Moreton Bay, Queensland,between March and June 1995. D. biperforata isdisc-shaped, with a test made up of organic matter,reinforced with sand grains. The species exhibitsdifferent test morphologies, the mostabundant type being the biperforate which hastwo holes, or lunules, through its test. A lesscommon type is the non-lunulate form, and themultiperforate and crescent-shaped types are rare.Possible abundance-substratum correlationswere studied and the results indicated that D.biperforata is strongly correlated to a band ofsiltier and more organic-rich sediment found atthe bottom of sand slopes running off MoretonIsland. There was a significant difference inabundance between Tangalooma, where themean abundance was 11.11 individuals persquare meter (SD = 3.63) and Shark Spit, whereit was found to be 7.73 individuals per squaremeter (SD = 3.06). No patchiness was apparentwithin the areas of siltier and organic-rich sediments.There was no significant difference in theratio between the different forms within the areassampled, but a size difference was apparentbetween locations, with larger specimens foundat Tangalooma. The mean size of the specimensfound was 27.7 mm in diameter. D. biperforatais the most abundant macrofaunal species in thearea studied.72
