THE THECAMOEBIAN BIBLIOGRAPHY 2Nd Edition Palaeontologia Electronica http://palaeo-electronica.org Preamble to the 2nd Edition. Since the publication of the first edition we have collected about 1,000 new titles which are inserted in the second edition. All the remarks and caveats in the Introduction are valid for both editions. The first edition of this document was published in 1999. THE THECAMOEBIAN BIBLIOGRAPHY 2nd Edition F.S. Medioli, L. Bonnet, David B. Scott, and Barbara Elizabeth Medioli ABSTRACT The literature on thecamoebians can be rather confusing, partly because it has been published in many different languages, but mainly because these Rhizopoda have been the subject of study for a wide array of researchers with very different inter- ests. Not only has this resulted in fragmentation of the literature due to research results being published in journals specializing in different fields, but inevitably has also resulted in development of a chaotic terminology and nomenclature. For example there is even confusion as to what to call the group, as terms such as "rhizopods," "testate amoebae," and "arcellaceans" have all been used by various authors as synonyms of "Thecamoebians." Even more confusing is the nomenclature of the described the- camoebian species. Lack of access to the literature and limited interchange between the various research groups has generated many synonyms. Although only a first step this fairly complete bibliography on thecamoebians has been compiled to assist researchers become more aware of the available literature. F.S. Medioli, David B. Scott.

As a result we have indirectly accumulated a large num- ber of references (well over 3000) which we report in this bibliography. We hope that this information will be a useful reference for researchers interested in working with fossil and sub-fossil thecamoebians. The World Wide Web is a perfect vehicle to dis- seminate this type of information. The literature on thecamoebians can be rather confusing, partly because it is in many different lan- guages but mainly because it is pub- lished in journals specialized in different fields. Inevitably, this has resulted in a somewhat chaotic termi- nology and nomenclature, so that terms such as "rhizopods," "testate amoebae," and "arcellaceans" have been used by various authors as syn- onyms of "Thecamoebians" (e.g., Figure 1 and Figure 2). The term "Arcellacea," often used as a syn- onym of Thecamoebians, is just a Superfamily of the Order Arcellinida, while "Thecamoebians" (Loeblich and Tappan, 1964) is an informal name, indicative of a polyphyletic [i.e., coming from different Classes] "group" of convenience, including part of the class Rhizopodea, Sub- class Lobosia, Orders Arcellinida, as well as part of the Class Reticularea, Subclass Filosia, Order Gromida Figure 1.

The organization of many old journals, actual article. In other cases we were unable to for example, can be very confusing. For example, many learned societies published the transcripts of 2 MEDIOLI, BONNET, SCOTT AND MEDIOLI: THE THECAMOEBIAN BIBLIOGRAPHY oral presentation under two dates: the date of presentation and the date of publication of the journal. In addition, some authors were in the habit of presenting the same paper at meetings of different societies. It was sometimes frus- trating for us to find, often after lengthy searches, that we had simply obtained a second copy of the same paper. To avoid similar struggles for users of this bibliog- raphy, we indicate when we know this is the case. For some recent references, particularly European ones printed in local journals, we often had pre-prints with pagination dif- ferent from the final one or no pagination at all; we could not do much about these. We apologize for the relatively few tentative or vague references, and for the abundant mistakes that we proba- bly inherited from other authors' bibliographies. We feel they are better leads than no reference at all. Whenever we were aware of problems, however, we made it clear by inserting the symbol (??). In a few cases, particularly amongst the very old references, our entries are "derived" from other authors' bibliographies, and we have not seen the original published papers. Knowing that some earlier authors were at times somewhat inaccurate in their bibliographies, we do not rule out the possibility that some of our entries may lead nowhere. We definitely know that some of Figure 2. Modified from Cash, J., and Hopkinson, J. 1909. The British these authors did occasionally ref- freshwater Rhizopoda and Heliozoa: v.

Amoebozoa is a major, early-diverging lineage of eukaryotes, containing at least 2,400 species. At present, 32 mitochondrial genomes belonging to 18 amoebozoan species are publicly available. A dearth of information is particularly obvious for two major amoebozoan clades, Variosea and Tubulinea, with just one mitochondrial genome sequenced for each. The main focus of this review is to summarize features such as mitochondrial gene content, mitochondrial genome size variation, and presence or absence of RNA editing, showing if they are unique or shared among amoebozoan lineages. In addition, we underline the potential of mitochondrial genomes for multigene phylogenetic reconstruction in Amoebozoa, where the relationships among lineages are not fully resolved yet. With the increasing application of next-generation sequencing techniques and reliable protocols, we advocate mitochondrial

  • Protozoologica Special Issue: Protists in Soil Processes
    Acta Protozool. (2012) 51: 271–289 http://www.eko.uj.edu.pl/ap ActA doi:10.4467/16890027AP.12.022.0768 Protozoologica Special issue: Protists in Soil Processes Testate Amoebae as Proxy for Water Level Changes in a Brackish Tidal Marsh Marijke OOMS, Louis BEYENS and Stijn TEMMERMAN University of Antwerp, Department of Biology, Ecosystem Management Research Group (ECOBE), Belgium Abstract. Few studies have examined testate amoebae assemblages of estuarine tidal marshes. This study investigates the possibility of us- ing soil testate amoebae assemblages of a brackish tidal marsh (Scheldt estuary, Belgium) as a proxy for water level changes. On the marsh surface an elevation gradient is sampled to be analyzed for testate amoebae assemblages and sediment characteristics. Further, vegetation, flooding frequency and soil conductivity have been taken into account to explain the testate amoebae species variation. The data reveal that testate amoebae are not able to establish assemblages at the brackish tidal marsh part with flooding frequencies equal to or higher than 36.5%. Further, two separate testate amoebae zones are distinguished based on cluster analysis. The lower zone’s testate amoebae species composition is influenced by the flooding frequency (~ elevation) and particle size, while the species variability in the higher zone is related to the organic content of the soil and particle size. These observations suggest that the ecological meaning of elevation shifts over its range on the brackish tidal marsh. Testate amoeba assemblages in such a brackish habitat show thus a vertical zonation (RMSEP: 0.19 m) that is comparable to the vertical zonation of testate amoebae and other protists on freshwater tidal marshes and salt marshes.

Testate amoebae in Vietnam are still poorly investigated. We studied species composition of testate amoebae in 47 waterbodies of South Vietnam provinces including natural lakes, reservoirs, wetlands, rivers, and irrigation channels. A total of 109 species and subspe- cies belonging to 16 genera, 9 families were identified from 191 samples. Thirty-five species and subspecies were observed in Vietnam for the first time. New speciesDifflugia vietnamica sp. nov. is described. The most species-rich genera are Difflugia (46 taxa), Arcella (25) and Centropyxis (14). Centropyxis aculeata was the most common species (observed in 68.1% samples). Centropyxis aerophila sphagniсola, Arcella discoides, Difflugia schurmanni and Lesquereusia modesta were characterised by a frequency of occurrence >20%. Other spe- cies were rarer. The species accumulation curve based on the entire dataset of this work was unsaturated and well fitted by equation S = 19.46N0.33. Species richness per sample in natural lakes and wetlands were significantly higher than that of rivers (p < 0.001). The result of the Spearman rank test shows weak or statistically insignificant relationships between species richness and water temperature, pH, dissolved oxygen, and electrical conductivity.

Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane).
