Falkenbergia Rufolanosa
''Asparagopsis armata'' is a species of marine red algae, in the family Bonnemaisoniaceae. English name(s) include red harpoon weed. They are multicellular eukaryotic organisms. This species was first described in 1855 by Harvey, an Irish botanist who found the algae on the Western Australian coast. ''A. armata'' usually develops on infralittoral rocky bottoms around the seawater surface to around 40m of depth. Marine algae like ''A. armata'' are considered “autogenic ecosystem engineers” as they are at the very bottom of the food chain and control resource availability to other organisms in the ecosystem. Population distribution ''A. armata'' is a species native to southern Australia and New Zealand (Southern hemisphere) and is thought to have slowly spread to the Northern hemisphere through the Mediterranean sea, as it is highly invasive. It can now also be found along the British Isles to Senegal as well. The first Mediterranean ''A. armata'' was reported in Algeria in 1 ...

Naccariaceae
Naccariaceae is a family of red algae in the order Bonnemaisoniales, with 3 monotypic genera. Which are found in both the Pacific and Atlantic Oceans. History It was circumscribed by Harald Kylin in 1928. When established the family only had 2 genera, ''Atractophora'' and ''Naccaria''. It was also suggested in 1987 (by Gabrielson and Garbary) and in 1997 (by Abbot) that the genera should be placed in the Gigartinales Order. But (Hommersand and Fredericq, 1990) said that the similarities in nutritive cells and carpospore germination, noted that the order Bonnemaisoniales was better used instead, Womersley, 1996 agreed.John Marinus Huisman The family is not monophyletic. Description They have a thallus (gametophyte) which is erect, mucosoid and irregularly radially branched. The structure is uniaxial; axial cells initially ecorticate (without a cortex), but eventually with a cortex, or surrounded by rhizoids (protuberances that extend from the lower epidermal cells) that can be s ...

Florideophyceae
Florideophyceae is a class of red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. Classification There are various classification schemes; see red algae. One option is to use the following: Subclass Hildenbrandiophycidae * Hildenbrandiales Subclass Nemaliophycidae * Acrochaetiales * Balbianiales * Balliales * Batrachospermales * Colaconematales * Nemaliales * Palmariales * Entwisleiales * Thoreales Subclass Corallinophycidae * Corallinales * Corallinapetrales * Rhodogorgonales * Sporolithales The subclass Corallinophycidae was introduced in 2007. Subclass Ahnfeltiophycidae * Ahnfeltiales * Pihiellales Subclass Rhodymeniophycidae * Bonnemaisoniales * Ceramiales * Gelidiales * Gigarti ...

Jean Feldmann
Jean Feldmann (1905–1978) was a French biologist, specialising in marine algae. Biography Jean Feldmann was born on 25 June 1905 in Paris. He initially studied pharmacy, gaining his first degree in 1929, before turning his attentions to marine algae. In 1933, he took up a position as an assistant at the University of Algiers, where he also completed his doctorate in 1937, married his assistant, Geneviève Mazoyer, in 1938, and rose to professor in 1948. The couple moved to Paris when Jean took up a position at the institution that became the Université Pierre et Marie Curie, where they remained until his retirement in 1976. He died suddenly on 18 September 1978. Work Feldmann published around 220 scientific works, mostly on marine algae, but also covering various fungi, mosses, freshwater algae and flowering plants. Feldmann strongly believed in international scientific co-operation and, as well as co-founding the Société Phycologique de France in 1955, strongly advocated ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
