Tetraphidaceae
Tetraphidaceae is a family of mosses. It includes only the two genus, genera ''Tetraphis'' and ''Tetrodontium'', each with two species. The defining feature of the family is the 4-toothed peristome. Range This family of mosses is most commonly found in northern latitudes. ''Tetraphis'' ''Tetraphis pellucida'' is the most common species in the family and is usually found in deciduous forests. Its leaves become wider in colder climates, which often leads to a misclassification of the species. ''Tetraphis geniculata'' is less commonly found and also appears in northern latitudes. The species often grows alongside the only other species in the genus, ''T. pellucida''. Both ''Tetraphis'' species are found growing on moist sedimentary rocks and also on soil with high organic content, but the genus is mostly found growing on rotting logs. ''Tetrodontium'' ''Tetrodontium brownianum'' grows most frequently on wet and shady rocks, of either granite or sandstone. The species norm ...

Tetrodontium Repandum
''Tetrodontium repandum'', the small four-tooth moss, is a moss in the family Tetraphidaceae.Schwägrichen, Christian Friedrich. Species Muscorum Frondosorum, Supplementum Secundum 2: 102. 1824. It is one of only two recognized species in the genus '' Tetrodontium'', and is native to subalpine regions of the Northern Hemisphere. It has been reported from Alaska, British Columbia, Washington state, Japan, and Europe.

Tetraphis Pellucida
''Tetraphis pellucida'', the pellucid four-tooth moss, is one of two species of moss in the acrocarpous genus ''Tetraphis''. Its name refers to its four large peristome teeth found on the sporophyte capsule. Range and morphology ''Tetraphis pellucida'' occurs almost exclusively on rotten stumps and logs, and is native to the northern hemisphere. The leafy shoot is between eight and 15 mm tall. The lower leaves are 1 to 2 mm long, whereas the upper and perichaetial leaves – leaves that surround the archegonia – are 3 mm long. The leaves are plain and whole at the margins. Reproduction ''Tetraphis pellucida'' reproduces both asexually through the production of gemmae, and sexually resulting in a sporophyte which will produce spores. Asexual reproduction ''Tetraphis pellucida'' reproduces asexually through the use of propagules called gemmae. The gemmae are found either in gemma cups or stalks. Gemma cups are typically composed of three to five larger, speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andreaeaceae
Andreaeaceae is a family of mosses which includes two genera, '' Andreaea'', containing about 100 species, and the genus '' Acroschisma''. The Andreaeaceae prefer rocky habitats ranging from tropical to arctic climates, on which they form tufted colonies, typically with reddish to blackish shoots. The capsules lack the peristome mechanism and dehisce longitudinally to release the spores, resulting in a paper-lantern appearance. It was named by Jakob Friedrich Ehrhart in honour of his friend J.G.R. Andreae.Transactions of the Linnean Society of London, Volume 10, p. 381, Linnean Society of London The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and Taxonomy (biology), taxonomy.

Sphagnopsida
Sphagnopsida is a class of mosses that includes a single subclass Sphagnidae, with two orders. It is estimated it originated about 465 million years ago, along with Takakia. The order Sphagnales contains four living genera: '' Ambuchanania'', '' Eosphagnum'', and '' Flatbergium'', which counts four species in total, and ''Sphagnum ''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat).

Christian Friedrich Schwägrichen
Christian Friedrich Schwägrichen (16 September 1775, Leipzig – 2 May 1853, Leipzig) was a German botanist specializing in the field of bryology. In 1799, he obtained his medical doctorate from the University of Leipzig, where he was later an associate professor of natural history (1803–1815) and afterwards a full professor on the same subject (1815–1852). Concurrently, he served as an associate professor of botany (1807–1852) at Leipzig.Professorenkatalog der Universität Leipzig , catalogus professorum lipsiensium (biography) Prior to 1837, he was director of the at Leipzig, being ...

Johann Hedwig
Johann Hedwig (8 December 1730 – 18 February 1799), also styled as Johannes Hedwig, was a German botanist notable for his studies of mosses. He is sometimes called the "father of bryology". He is known for his particular observations of sexual reproduction in the cryptogams. Many of his writings were in Latin, and his name is rendered in Latin as Ioannis Hedwig or Ioanne Hedwig. Early life Hedwig was born in Brașov, Transylvania, on 8 December 1730. As the son of a shoemaker, he grew up in poverty. It was in his childhood he became fascinated with mosses.Isely, Duane. One Hundred and One Botanists. Purdue University Press, 2002. He went on to study medicine at the University of Leipzig, and received his medical degree in 1759. Career After receiving his degree, Hedwig worked as a physician for the next twenty years. When he was not granted a license to practice in Transylvania with his Leipzig degree, he worked as a general practitioner in Chemnitz. It was during this tim ...

Protonema
A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses. When a moss first grows from a spore, it starts as a ''germ tube'', which lengthens and branches into a filamentous complex known as a ''protonema'', from which a leafy gametophore, the adult form of a gametophyte in bryophytes, grows. Protonemata are characteristic of all mosses, are present in some liverworts under certain conditions Kohchi, T., Yamato, K. T., Ishizaki, K., Yamaoka, S., & Nishihama, R. (2021).

The protonemata are composed of two cell types: chloronemata, which form upon germination of the spore, and caulonemata, which later differentiate from chloronemata under the influence of plant hormone a ...

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...

Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
