Parmotrema tinctorum is a lichen which belongs to the Parmotrema genus. The lichen is as known as the Palm Ruffle Lichen and is listed as secure by the Nature Conservatory. [1]
Grows to around 3–30 cm in diameter with board dull smooth slightly shiny gray lobes that are 10–20 mm wide. The underside is black with naked brown areas with a central collection of simple rhizines. [2] [3]
Global distribution with a majority of samples being located in North America and Europe. [4]
Compounds derived from Parmotrema tinctorum have been found to have anti-cancer properties. [5]
Parmotrema tinctorum has been identified and used as a candidate for monitoring air pollution. [6] [7] [8]
Methylketol or 2-methylindole is a mildly toxic and slightly flammable organic compound which occurs as a white solid which turns brown over time. It has chemical formula C9H9N.
Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.
Pounce or sand is a fine powder, most often made from powdered cuttlefish bone or sandarac resin, that was used both to dry ink and to sprinkle on a rough writing surface to make it smooth enough for writing. This was especially needed if the paper came "unsized", that is, lacking the thin gelatinous material used to fill the surface of the paper and make it smooth enough for writing with a quill or a steel nib. It was also used to prepare the surface when drafting with Rapidograph pens on mylar, a common drafting medium in the late twentieth century.
Artocarpus odoratissimus is a species of flowering plant in the Moraceae family. It is a commonly called marang, madang, timadang, terap, tarap, kiran, green pedalai, or johey oak. It is native to Borneo, Palawan, and Mindanao Island, and is closely related to the jackfruit, cempedak, and breadfruit trees which all belong to the same genus, Artocarpus.
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
Polar fleece is a soft napped insulating fabric made from polyester.
Rhizopus arrhizus is a fungus of the family Mucoraceae, characterized by sporangiophores that arise from nodes at the point where the rhizoids are formed and by a hemispherical columella. It is the most common cause of mucormycosis in humans and occasionally infects other animals.
Ticks are insects known for attaching to and sucking blood from land-dwelling animals. Ticks fall under the category of 'arthropod', and while they are often thought of in the context of disease transmission, they are also known to cause direct harm to hosts through bites, toxin release, and infestation. Infestation can cause symptoms ranging from mild to severe and may even cause death. Hosts can include any number of vertebrates, though humans and livestock are more likely to be the interest of researchers.
Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.
Raphidocelis subcapitata, formerly known as Selenastrum capricornutum and Pseudokirchneriella subcapitata is a microalga. This microalga presents a curved and twisted appearance like a sickle. The cells are normally presented in a solitary form. It has a length between 8 and 14 μm, and a width between 2 and 3 μm. It is commonly used as a bioindicator species to assess the levels of nutrients or toxic substances in freshwater environments. This species is quite sensitive to the presence of toxic substances including metals and has a ubiquitous distribution, so is broadly used in ecotoxicology. This species has been found to be more competitive than Chara vulgaris at low sodium chloride concentrations, but C. vulgaris was more competitive under salt stress.
Pollution-induced community tolerance (PICT) is an approach to measuring the response of pollution-induced selective pressures on a community. It is an eco-toxicological tool that approaches community tolerance to pollution from a holistic standpoint. Community Tolerance can increase in one of three ways: physical adaptations or phenotypic plasticity, selection of favorable genotypes, and the replacement of sensitive species by tolerant species in a community.
Methylorubrum rhodesianum is a species of alphaproteobacteria. It has been found on the International Space Station (ISS) amongst others.
Bacillus thuringiensis subsp. kurstaki (Btk) is a group of bacteria used as biological control agents against lepidopterans. Btk, along with other B. thuringiensis products, is one of the most widely used biological pesticides due to its high specificity; it is effective against lepidopterans, and it has little to no effect on nontarget species. During sporulation, Btk produces a crystal protein that is lethal to lepidopteran larvae. Once ingested by the insect, the dissolution of the crystal allows the protoxin to be released. The toxin is then activated by the insect gut juice, and it begins to break down the gut.
Lecanoric acid is a chemical produced by several species of lichen. Lecanoric acid is classified as a polyphenol and a didepside and it functions as an antioxidant. The acid is named after the lichen Lecanora. The acid has also been isolated from Usnea subvacata, Parmotrema stuppuem, Parmotrema tinctorum,Parmotrema grayana, Xanthoparmelia arida and Xanthoparmelia lecanorica. A related compound, 5-chlorolecanoric acid, is found in some species of Punctelia.
Parmotrema abessinicum is a species of corticolous lichen in the family Parmeliaceae. It has been recorded from Africa, Asia, and Oceania.
Barbara Louise Chilvers is a New Zealand marine biologist who researches marine mammals. She is Professor of Wildlife Ecology in the School of Veterinary Science at Massey University and Director of Wildbase Oiled Wildlife Response at the university.
Salazinic acid is a depsidone with a lactone ring. It is found in some lichens, and is especially prevalent in Parmotrema and Bulbothrix, where its presence or absence is often used to help classify species in those genera.
Auricularia mesenterica, commonly known as the tripe fungus, is a species of fungus in the family Auriculariaceae. Basidiocarps grow in undulating densely-packed shelves that adopt a partially resupinate form. A. mesenterica feeds saprotrophically on a number of woody substrates in deciduous forests.
Parmotrema stuppuem is a corticolous (bark-dwelling), foliose lichen that belongs to the large family Parmeliaceae. The lichen is commonly known as the powder-edged ruffle lichen and is listed as apparently secure by the Nature Conservancy.
