It includes taxa described or recorded from the beginning of January 2021 up to the end of May 2021, plus 3 species that were named in 2020 which were missed. Please note that only higher taxa that include new taxa or changed/corrected records are listed below. The list is until the end of May, however some papers published in June are listed in the ‘in press’ section at the end, but taxa from these are not yet included in the checklist. As per the previous on-line checklists, in the bibliography page numbers have been added (in blue) to those papers that were published on-line previously without page numbers. New additions or changes to the previously published list and supplements are marked in blue, corrections are marked in red. In Ross (2021) new species of spider from Wunderlich & Müller (2020) were listed as being authored by both authors because there was no indication next to the new name to indicate otherwise, however in the introduction it was indicated that the author of the new taxa was Wunderlich only. Where there have been subsequent taxonomic changes to any of these species the authorship has been corrected below.

  • Culturing Slime Mold
    Culturing Slime Mold Live Material Care Guide SCIENTIFIC BIO Background FAX! Plasmodial slime mold (phylum Myxomycota) lives in dark, moist environments such as under the bark of decaying logs, among mulch, or beneath decaying leaves. Slime mold classification is once again changing. They were in Protista due to their amoeboid-like properties. In the past, slime molds were considered a fungus because they produce fruiting bodies and spores used for reproduction. Slime molds are a group notable for its unwillingness to be neatly classified! Frequently bright in color and large in size (up to 30 cm in diameter), plasmodial slime molds consist of many amoeba-like cells, which form a mass of protoplasm called myxomycota. The organisms are capable of very slow, creeping movement by means of cytoplasmic streaming. During the reproductive stage, called pseudoplasmodium, slime molds tend to migrate to a well-lit area, such as the top of a log, where less moisture is present. They form into a slug-like mass and produce reproductive fruiting bodies, which contain spores. Under adverse conditions (lack of food, water, light, warmth, or pH changes), the organism dries out and forms a hardened mass called a sclerotium. These sclerotia may also grow fruiting bodies, but do not release spores into the environ- ment until conditions once again become favorable for growth. Spores are transported by wind, which results in the spreading of slime molds to new areas. Sclerotium (unfavorable conditions) Pseudoplasmodium (favorable conditions) Aggregate (plasmodial stage) Amoeba/spores Reproductive Fruiting Bodies Figure 1. Life Cycle of Slime Mold Culturing/Media Slime mold is typically cultured from sclerotia rather than from spores.

  • Comparison of ​Physarum Polycephalum​Growth Rate On
    AP Research Comparison of Physarum Polycephalum Growth Rate on ​ ​ Various Nutrients Word count: 4,003 Comparison of Physarum Polycephalum Growth Rate on Various Nutrients ​ ​ Abstract The growth rate of Physarum Polycephalum (slime mold) was measured to determine ​ ​ what type of food results in the largest increase in surface area across a petri dish. Old fashioned oat flakes, the most commonly used nutrient for slime mold, was compared against 5 other food sources to determine if there is a food other than oat flakes that could yield a higher growth rate. The growth rates were measured with time lapse cameras over the course of three days. Over the duration of the recorded growth, it was concluded that the old fashioned oat flakes yielded the highest growth rate. Introduction Slime mold is a single celled protist that is visible to the naked eye. Slime mold is naturally found in the dark, moist climates that exist on decaying leaves and logs in forest areas. The protist consumes fungal spores, bacteria, and other microbes by means of engulfing (Dagamac 2015). To find its prey, slime mold is able to explore its environment “by spontaneous and self-organised oscillatory contractions” (Jones 2015). This means that the slime mold is able to contract its body in an organized way, allowing the slime mold to slowly push itself in all directions. When a slime mold encounters a new food source, it is able to connect the new food source to it’s pre existing ones. To conserve mass, the slime mold gradually funnels the link between the food sources to a single ‘protoplasmic’ tube.

  • The Cellular Slime Mold: Eukaryotic Model Microorganism
    Exp. Anim. 58(2), 97–104, 2009 —Review— Review Series: Animal Bioresource in Japan The Cellular Slime Mold: Eukaryotic Model Microorganism Hideko URUSHIHARA Graduate School of Life and Environmental Sciences, University of Tsukuba, 1–1–1 Tennodai, Tsukuba, Ibaraki 305-8572, Japan Abstract: Cellular slime molds are eukaryotic microorganisms in the soil. They feed on bacteria as solitary amoebae but conditionally construct multicellular forms in which cell differentiation takes place. Therefore, they are attractive for the study of fundamental biological phenomena such as phagocytosis, cell division, chemotactic movements, intercellular communication, cell differentiation, and morphogenesis. The most widely used species, Dictyostelium discoideum, is highly amenable to experimental manipulation and can be used with most recent molecular biological techniques. Its genome and cDNA analyses have been completed and well-annotated data are publicly available. A larger number of orthologues of human disease-related genes were found in D. discoideum than in yeast. Moreover, some pathogenic bacteria infect Dictyostelium amoebae. Thus, this microorganism can also offer a good experimental system for biomedical research. The resources of cellular slime molds, standard strains, mutants, and genes are maintained and distributed upon request by the core center of the National BioResource Project (NBRP-nenkin) to support Dictyostelium community users as well as new users interested in new platforms for research and/or phylogenic consideration.

To access permit conditions, click here. Never purchase living specimens without having a disposition strategy in place. There are currently no USDA permits required for this organism. In order to protect our environment, never release a live laboratory organism into the wild. Primary Hazard Considerations Always wash your hands thoroughly before and after you handle your cultures, or anything it has touched. It is recommended to use gloves when working with mold, fungus, or bacteria. Availability Physarum is available year round. Care Habitat • Plasmodial stage are shipped in a Petri dish on Physarum agar with oats. Your Physarum should be bright yellow in color, and fan shaped. If your Physarum takes on a different appearance it may be contaminated. Contaminated cultures occur when a foreign specimen (something other than Physarum) makes its way onto your culture. This culture should be stored at room temperature in a dark place. The culture should be viable for about 1–2 weeks in its current container. • Sclerotia are hardened masses of irregular form consisting of many minute cell-like components. These are shipped on cut strips of filter paper in a tube. The culture should be stored at room temperature and can be stored in this stage for several months. Care: • Physarum is subcultured onto Physarum agar, and is incubated at room temperature or 25 °C. To maintain viability, plasmodial Physarum should be subcultured weekly.

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1176. 48 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9031-7. There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto- mitochondrion. This gives a relatively short distance between ingroup (eukaryotes) and outgroup (mitochondrial progenitor), which is important for accurate rooting. The resulting phylogeny reconstructs three eukaryote megagroups and places one, Discoba (Excavata), as sister group to the other two (neozoa). This rejects the reigning “Unikont-Bikont” root and highlights the evolutionary importance of Excavata. For Paper II, I developed a 150-gene dataset to test relationships in supergroup SAR (Stramenopila, Alveolata, Rhizaria). Analyses of all 150-genes give different trees with different methods, but also reveal artifactual signal due to extremely long rhizarian branches and illegitimate sequences due to horizontal gene transfer (HGT) or contamination.

  • A Would-Be Nervous System Made from a Slime Mold
    A Would-Be Nervous System Andrew Adamatzky** Made from a Slime Mold University of the West of England Keywords Slime mold, nervous system, unconventional computing Abstract The slime mold Physarum polycephalum is a huge single cell that has proved to be a fruitful material for designing novel computing architectures. The slime mold is capable of sensing tactile, chemical, and optical stimuli and converting them to characteristic patterns of its electrical potential oscillations. The electrical responses to stimuli may propagate along protoplasmic tubes for distances exceeding tens of centimeters, as impulses in neural pathways do. A slime mold makes decisions about its propagation direction based on information fusion from thousands of spatially extended protoplasmic loci, similarly to a neuron collecting information from its dendritic tree. The analogy is distant yet inspiring. We speculate on whether alternative—would-be—nervous systems can be developed and practically implemented from the slime mold. We uncover analogies between the slime mold and neurons, and demonstrate that the slime mold can play the roles of primitive mechanoreceptors, photoreceptors, and chemoreceptors; we also show how the Physarum neural pathways develop. The results constituted the first step towards experimental laboratory studies of nervous system implementation in slime molds. 1 Introduction The plasmodium of Physarum polycephalum (order Physarales, class Myxomecetes, subclass Myxo- gastromycetidae) is a single cell, visible with the naked eye, with many diploid nuclei [63]. The plasmodium feeds on bacteria and microscopic food particles by endocytosis. When placed in an environment with distributed sources of nutrients, the plasmodium forms a network of proto- plasmic tubes connecting the food sources (Figure 1a).
