Diplonema is a genus of free-living organisms in the Euglenozoa. They are distinguished from Rhynchopus in Class Diplonemea by the absence of a fully flagellate dispersive stage.

Characteristics

Diplonema feature two short flagella of equal length and two subapical openings. Most are free living, but there have been reported cases of infection in clams and sudden decomposition of aquarium plants. It was described initially in 1913 and later rediscovered in the 60s and called Isonema, wrongly classified among euglenids. [1] [2]

<span class="mw-page-title-main">Freemasonry</span> Group of fraternal organizations

Freemasonry or Masonry refers to fraternal organisations that trace their origins to the local guilds of stonemasons that, from the end of the 14th century, regulated the qualifications of stonemasons and their interaction with authorities and clients. Modern Freemasonry broadly consists of two main recognition groups: Regular Freemasonry, which insists that a volume of scripture be open in a working lodge, that every member professes belief in a Supreme Being, that no women be admitted, and that the discussion of religion and politics do not take place within the lodge; and Continental Freemasonry, which consists of the jurisdictions that have removed some, or all, of these restrictions.

The flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates, and have no specialised circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion and egestion ; as a result, the food cannot be processed continuously.

<span class="mw-page-title-main">Free people of color</span> Persons of partial African and European descent who were not enslaved

In the context of the history of slavery in the Americas, free people of color were primarily people of mixed African, European, and Native American descent who were not enslaved. However, the term also applied to people born free who were primarily of black African descent with little mixture. They were a distinct group of free people of color in the French colonies, including Louisiana and in settlements on Caribbean islands, such as Saint-Domingue (Haiti), St. Lucia, Dominica, Guadeloupe, and Martinique. In these territories and major cities, particularly New Orleans, and those cities held by the Spanish, a substantial third class of primarily mixed-race, free people developed. These colonial societies classified mixed-race people in a variety of ways, generally related to visible features and to the proportion of African ancestry. Racial classifications were numerous in Latin America.

An aviary is a large enclosure for confining birds, although bats may also be considered for display.

Aviaries often contain plants and shrubbery to simulate a natural environment.

<i>Encyclopedia of Life</i> Free, online collaborative encyclopedia that documents species

The Encyclopedia of Life (EOL) is a free, online encyclopedia intended to document all of the 1.9 million living species known to science. It is compiled from existing trusted databases curated by experts and with the assistance of non-experts throughout the world. It aims to build one "infinitely expandable" page for each species, including video, sound, images, graphics, as well as text. In addition, the Encyclopedia incorporates content from the Biodiversity Heritage Library, which digitizes millions of pages of printed literature from the world's major natural history libraries. The project was initially backed by a US$50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation, who provided US$20 million and US$5 million, respectively. The additional US$25 million came from five cornerstone institutions—the Field Museum, Harvard University, the Marine Biological Laboratory, the Missouri Botanical Garden, and the Smithsonian Institution. The project was initially led by Jim Edwards and the development team by David Patterson. Today, participating institutions and individual donors continue to support EOL through financial contributions.

Stoicism is a school of Hellenistic philosophy that flourished in Ancient Greece and Ancient Rome. The Stoics believed that the practice of virtue is enough to achieve eudaimonia: a well-lived life. The Stoics identified the path to achieving it with a life spent practicing certain virtues in everyday life such as courage or temperance and living in accordance with nature. It was founded in the ancient Agora of Athens by Zeno of Citium around 300 BC.

<span class="mw-page-title-main">Circumscription (taxonomy)</span> Definition of a taxon

In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus.

The proletariat is the social class of wage-earners, those members of a society whose only possession of significant economic value is their labour power. A member of such a class is a proletarian or a proletaire. Marxist philosophy regards the proletariat under conditions of capitalism as an exploited class - forced to accept meager wages in return for operating the means of production, which belong to the class of business owners, the bourgeoisie.

<span class="mw-page-title-main">Diplonemidae</span> Family of protozoans

Diplonemidae is a family of biflagellated unicellular protists that may be among the more diverse and common groups of planktonic organisms in the ocean. Although this family is currently made up of three named genera; Diplonema, Rhynchopus, and Hemistasia, there likely exist thousands of still unnamed genera. Organisms are generally colourless and oblong in shape, with two flagella emerging from a subapical pocket. They possess a large mitochondrial genome composed of fragmented linear DNA. These non-coding sequences must be massively trans-spliced, making it one of the most complicated post-transcriptional editing process known to eukaryotes.
