The Seirococcaceae are a family of brown algae, containing five genera: [1] [2]
Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science.
The brown algae, comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, Macrocystis, a kelp of the order Laminariales, may reach 60 m (200 ft) in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is Sargassum, which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food.
Cystophora is a genus of brown algae.
Nizamuddin Dargah is the dargah (mausoleum) of the Sufi saint Khwaja Nizamuddin Auliya. Situated in the Nizamuddin West area of Delhi, the dargah is visited by thousands of pilgrims every week. The site is also known for its evening qawwali devotional music sessions. The descendants of Nizamuddin Auliya look after the whole management of dargah Sharif.
Chordariaceae is a family of brown algae. Members of this family are may be filamentous, crustose with fused cells at the base, or they may be terete and differentiated into a central medulla and an outer photosynthetic cortex. They have a sporphytic thallus usually aggregated to form a pseudo-parenchyma.
Cystoseira is a genus of brown algae in the order Fucales.
Ectocarpales is a very large order in the brown algae. The order includes families with pseudoparenchymatous (Splachnidiaceae) or true parenchymatous (Scytosiphonaceae) tissue. Pseudoparenchymatous refers to a filamentous alga with cells packed very close together to give an appearance of parenchymatous tissue, the latter being composed of cells which can truly divide in three dimensions, unusual among the algae. Filamentous algae are composed of cells that divide along a single plane, allowing only elongation to form filaments of one or more rows of cells. Algae that can divide in two planes can form sheet-like thalli or bodies. Cells that can divide in a third plane potentially allow for the organism to develop a more complex body plan, and diversification of body plans into an erect thallus of some sort and a holdfast for attaching the upright portion to the substrate.
Chaetophorales is an order of green algae in the class Chlorophyceae.
Dr Robert Kaye Greville FRSE FLS LLD was an English mycologist, bryologist, and botanist. He was an accomplished artist and illustrator of natural history. In addition to art and science he was interested in causes like abolitionism, capital punishment, keeping Sunday special and the temperance movement. He has a mountain in Queensland named after him.
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species.
Entally is an assembly constituency in Kolkata district in the Indian state of West Bengal.
Rhodymenia is a genus of red algae, containing the following species:
Laurencia is a genus of red algae that grow in temperate and tropical shore areas, in littoral to sublittoral habitats, at depths up to 65 m (213 ft).
Cystoseira foeniculacea is a species of brown alga in the genus Cystoseira.
Phyllophoraceae is a family of red algae in the order Gigartinales.
Phyllophora is a genus of red algae in the family Phyllophoraceae.
Dictyota is a genus of seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus.
2020 Tablighi Jamaat hotspot is a controversial religious congregation that took place in Delhi's Nizamuddin Markaz Mosque in early March 2020 was a coronavirus super-spreader event with more than 4,000 confirmed cases and at least 27 deaths linked to the event reported across the country. All of the foreign nationals have been acquitted by Indian courts citing malicious intention of the Ministry of home affairs Over 9,000 missionaries may have attended the congregation, with the majority being from various states of India, and 960 attendees from 40 foreign countries. On 18 April, 4,291 confirmed cases of COVID-19 linked to this event by the Union Health Ministry represented a third of all the confirmed cases of India. Around 40,000 people, including Tablighi Jamaat attendees and their contacts, were quarantined across the country.
