Cucubalus
''Silene'' is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many ''Silene'' species are widely distributed, particularly in the northern hemisphere. Scientific history Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many ''Silene'' species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMI19367316/ref> The genus has been used as a model for understanding the genetics of sex determination for over a century. ''Silene'' species commonly contain a mixture of hermaphroditic and female (or male-sterile) individuals (gynodioecy), an ...

Caryophyllaceae
Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 81 genera and about 2,625 known species. This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains. Some of the more commonly known members include pinks and carnations (''Dianthus''), and firepink and campions ('' Lychnis'' and ''Silene''). Many species are grown as ornamental plants, and some species are widespread weeds. Most species grow in the Mediterranean and bordering regions of Europe and Asia. The number of genera and species in the Southern Hemisphere is rather small, although the family does contain Antarctic pearlwort (''Colobanthus quitensis''), the world's southernmost dicot, which is one ...

Silene Dioica
''Silene dioica'' ( syn. ''Melandrium rubrum''), known as red campion and red catchfly, is a herbaceous flowering plant in the family Caryophyllaceae, native throughout central, western and northern Europe, and locally in southern Europe. It has been introduced in Iceland, Canada, the US, and Argentina. Description It is a biennial or perennial plant, with dark pink to red flowers, each 1.8–2.5 cm across. There are five petals which are deeply notched at the end, narrowed at the base and all go into an urn-shaped calyx. As indicated by the specific name, male and female flowers are borne on separate plants (dioecious), the male with 10 stamens and a 10-veined calyx, the female with 5 styles and a 20-veined calyx. The fruit, produced from July onwards, is an ovoid capsule containing numerous seeds, opening at the apex by 10 teeth which curve back. The flowers are unscented. The flowering period is from May to October and the flowers are frequently visited by flies such as ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P. H. A. Sneath, 2003. A short histor ... states that the Section rank is an informal one, between the subgenus and species (as in botany). References Botanical no ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...

Noctuidae
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae. Description Adult: Most noctuid adults have drab wings, but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. '' Baorisa hieroglyphica''). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, whic ...

Hadena Bicruris
The lychnis (''Hadena bicruris'') is a moth of the family Noctuidae. It is found in northern and western Europe and Turkey. It has an Atlantic-Mediterranean distribution. In the East Palearctic it is replaced by '' Hadena capsincola''. Description This species has dark brown forewings marked with two prominent white-bordered stigmata and a white subterminal line. The hindwings are buffish, darkening to brown towards the margin but with a prominent white fringe. Seitz states - Distinguished from '' rivularis'' F. by the absence of the violet sheen; the markings white instead of yellow; the upper stigmata not conjoined; a conspicuous black blotch above inner margin near base; hindwing fuscous. Larva dull brown, with darker dorsal line and oblique subdorsal streaks. Biology One or two broods are produced each year and adults can be seen between May and September. Flight is from June to July. The larva feeds on various Caryophyllaceae such as ''Dianthus'', ''Lychnis'', ''Saponaria'' ...

Gynomonoecious
Gynomonoecy is defined as the presence of both female and hermaphrodite flowers on the same individual of a plant species. It is prevalent in Asteraceae but is poorly understood. It is a monomorphic sexual system alongside monoecy, andromonoecy and trimonoecy. Occurrence This sexual system occurs in about 2.8% of flowering plants. It is present in 3% of ''Silene'' species and 23 families of flowering plants, but is most common in the daisy family, Asteraceae. About 200 of the approximately 23000 species in the Asteraceae are gynomonoecious. Evolution Gynomonoecy may be an intermediate evolutionary state between monoecy and hermaphroditism. It is also hypothesized to be the ancestor to trimonoecy. Gynomonecy evolved once in Hawaiian ''Tetramolopium''. In families like Compositae or Chenopodiaceae Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''.

Andromonoecious
Andromonoecy is a breeding system of plant species in which male and hermaphrodite flowers are on the same plant. It is a monomorphic sexual system alongside monoecy, gynomonoecy and trimonoecy. Andromonoecy is frequent among genera with zygomorphic flowers, however it is overall rare and occurs in less than 2% of plant species. Nonetheless the breeding system has gained interest among biologists in the study of sex expression. Etymology The word andromonoecious is a combination of andr- (meaning male) and monoecious and was first used in 1877. Prevalence It is uncommon and has been estimated to occur in less than 2% of plant species. In angiosperms, it occurs in 1.7% of angiosperms making up around 4000 species in 33 families. It is common in the grass subfamily Panicoideae.

Trioecy
Trioecy, or subdioecy, is a rare sexual system characterized by the coexistence of males, females, and hermaphrodites. It has been found in both plants and animals. Trioecy is sometimes referred to as a mixed mating system alongside androdioecy and gynodioecy. Evolution of trioecy Many speculate trioecy is a transient state and is often associated with evolutionary transitioning from gynodioecy to dioecy. Other studies show that trioecious populations originated from gonochoristic ancestors which were invaded by a mutant selfing hermaphrodite, creating a trioecious population. It has been suggested that chromosomal duplication is an important part in the evolution of trioecy. Evolutionary stability Trioecy is usually viewed as evolutionarily unstable, but its exact stability is unclear. Like in brachiopod species trioecy usually breaks into androdioecy or gynodioecy. But one study found that trioecy can be stable under nucleocytoplasmic sex determination. Another theoretical ...
