Elaeomyxa
''Elaeomyxa'' is a genus of slime molds in the family Lamprodermataceae. , there are four known species in the genus. Species in this genus have been documented in North America, Eurasia, Africa, and Australasia. Biology The ''Elaeomyxa'' genus belongs to the true slime mold phylum Myxomycetes (also known as Mycetozoa) of fungus-like organisms that have at different times been classified in the protist, animal, and fungi kingdoms. Like other true slime molds, ''Elaeomyxa'' species have distinct life cycle phases. During the trophic stage, called the plasmodium, the slime mold ingests food in an amoebalike manner. The slime mold then transitions to the reproductive phase, in which fruiting bodies produce spores for reproduction. Species The ''Elaeomyxa'' genus contains the following species: *''Elaeomyxa australiensis'' (S.L.Stephenson, G.Moreno & H.Singer) G.Moreno, H.Singer & S.L.Stephenson, 2008 *''Elaeomyxa cerifera'' (G.Lister) Hagelst., 1942 *''Elaeomyxa miyazakiensis'' (E ...

Robert Hagelstein
Robert Hagelstein (May 16, 1870 – Oct. 20, 1945) was a multidisciplinary businessman, scientist, and microscopy expert who served for fifteen years as the Honorary Curator of Myxomycetes at the New York Botanical Garden. He is known for his work in algae and slime mold specimen collection and curation, and for making hands-on learning materials widely available to student and amateur scientists. Early life Robert Hagelstein was born in Brooklyn, New York on May 16, 1870. His earliest scientific explorations centered on minerals, but he later became interested in biology and microscopy. He graduated from high school in Brooklyn and developed his skills in microscopy at the Brooklyn Institute of Arts and Sciences. He lived for some time in Brooklyn and later moved to Mineola, New York, which was a short drive from one of his primary field sites for specimen collection. Career After graduating from high school, Hagelstein initially chose a career track in business with the J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plasmodium
''Plasmodium'' is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of ''Plasmodium'' species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect ( mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range. Evolutionary relationships among different ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytotaxa
''Phytotaxa'' is a peer-reviewed scientific journal for rapid publication on any aspect of systematic botany. It publishes on a wide range of subjects, but focuses on new species, monographs, floras, revisions, reviews, and typification issues. ''Phytotaxa'' covers all plant groups covered by the International Code of Nomenclature for algae, fungi, and plants, including diatoms, fungi, algae, lichens, mosses, hornworts, liverworts, and vascular plants), both living and fossil. The journal was established in 2009 by Maarten Christenhusz and the first issue appeared in October 2009. Authors have the option to publish open access. Abstracting and indexing The journal is abstracted and indexed in Science Citation Index Expanded, Current Contents/Agriculture, Biology & Environmental Sciences, and BIOSIS Previews.

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruiting Body
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a ''basidiocarp'' or ''basidiome'', while the fruitbody of an ascomycete is known as an '' ascocarp''. Many shapes and morphologies are found in both basidiocarps and ascocarps; these features play an important role in the identification and taxonomy of fungi. Fruitbodies are termed ''epigeous'' if they grow on the ground, while those that grow underground are '' hypogeous''. Epigeous sporocarps that are visible to the naked eye, especially fruitbodies of a more or less agaricoid morphology, are often called mushrooms. Epigeous sporocarps have mycelia that extend undergroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amoeba
An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebae do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals. Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. In older classification systems, most amoebae were placed in the class or subphylum Sarcodina, a grouping of single-celled organisms that possess pseudopods or move by protoplasmic flow. However, molecular phylogenetic studies have shown that Sarcodina is not a monophyletic group whose members share common descent. Consequently, amoeboid organisms are no longer classified together in one group.Jan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of ...
