Draparnaldia
''Draparnaldia'' is a genus of freshwater green algae in the family Chaetophoraceae. ''Draparnaldia'' are uniseriate; each filament is composed of a chain of cells arranged in one row. Chloroplasts appear as a band within the center of each cell. The length of the main axis cells are generally the same, regardless of whether or not they bear branches. These side branches are divided extensively into terminal hairs. The entire plant is enveloped in loose, slippery mucilage. ''Draparnaldia'' is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters. They are either attached to sand or grow epiphytically on other aquatic plants. ''Draparnaldia'' can be seen growing in clear streams trailing on stones and boulders . Herman S. Forest of The Southern Appalachian Botanical Club has stated that while not common, it is present frequently enough to be recorded in almost all local flora lists of green algae that have been compiled.

Jacques Philippe Raymond Draparnaud
Jacques Philippe Raymond Draparnaud (3 June 1772, Montpellier – 2 February 1804) was a French naturalist, malacologist and botanist. Draparnaud is considered the father of malacology in France. He was professor of medicine and pathology at the Faculté de Médecine de Montpellier. Draparnaud understood the breadth of the fauna he studied, as can be seen in a quote from him, in ''Histoire Naturelle des Mollusques'', published in 1805:Au reste, quoique j'aie décrit pour la France seule un bien plus grand nombre d'espèces que Muller et Schroeter n'ent ont fait connoître pour l'Europe entière, et trois fois autant que Geoffroy et Poiret n'en ont observé dans les environs de Paris, je suis convaincu qu'il reste encore en ce genre bien des découvertes à faire. Translation: As for the remainder, even though I have described for France a greater number of species than Müller and Schroeter made known for the whole of Europe, and three times as many as Geoffroy and Poiret obs ...

Draparnaudia
''Draparnaudia'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Partuloidea. ''Draparnaudia'' is the only genus in the family Draparnaudiidae. Both the family name and the genus name of these snails were created to honor the 18th century French malacologist Jacques Philippe Raymond Draparnaud. Distribution This genus is endemic to New Caledonia, in Melanesia and - probably introduced - to Vanuatu. Taxonomy The family Draparnaudiidae is classified within the informal group Orthurethra, itself belonging to the clade Stylommatophora within the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). ''Draparnaudia'' is the type genus of the family Draparnaudiidae. Draparnaudiidae consists of one genus with six species:Tillier S. & Mordan P. B. (1995).

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Circumscription (taxonomy)
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. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...
