Erythrina Excelsa
''Erythrina'' is a genus of plants in the pea family, Fabaceae. It contains about 130 species, which are distributed in tropical and subtropical regions worldwide. They are trees, with the larger species growing up to in height. The generic name is derived from the Greek word , meaning "red", referring to the flower color of certain species. Names Particularly in horticulture, the name coral tree is used as a collective term for these plants. Flame tree is another vernacular name, but may refer to a number of unrelated plants as well. Many species of ''Erythrina'' have bright red flowers, and this may be the origin of the common name. However, the growth of the branches can resemble the shape of sea coral rather than the color of ''Corallium rubrum'' specifically, and this is an alternative source for the name. Other popular names, usually local and particular to distinct species, liken the flowers' red hues to those of a male chicken's wattles, and/or the flower shape to it ...

Wiliwili
Wiliwili (''Erythrina sandwicensis''), is a species of tree in the pea family, Fabaceae, that is endemic to the Hawaiian Islands. It is the only species of '' Erythrina'' that naturally occurs there. It is typically found in Hawaiian tropical dry forests on leeward island slopes up to an elevation of . ''Wiliwili'' means "repeatedly twisted" in the Hawaiian language and refers to the seedpods, which dehisce, or twist open, to reveal the seeds. Description ''Wiliwili'' trees grow to a height of with a gnarled and stout trunk that reaches in diameter. The bark is smooth, slightly fissured, and covered in gray or black spines up to in length. The bark on the main trunk of mature trees has a distinct orange cast, which is caused by a terrestrial alga. The ''wiliwili'' is summer (dry season) drought deciduous. The dry season usually begins in late April or in May, and trees in the wild typically lose all of their leaves before they bloom. Trees in cultivation may retain muc ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infertility
Infertility is the inability of a person, animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects). It is the normal state of a human child or other young offspring, because they have not undergone puberty, which is the body's start of reproductive capacity. In humans, infertility is the inability to become pregnant after one year of unprotected and regular sexual intercourse involving a male and female partner.Chowdhury SH, Cozma AI, Chowdhury JH. Infertility. Essentials for the Canadian Medical Licensing Exam: Review and Prep for MCCQE Part I. 2nd edition. Wolters Kluwer. Hong Kong. 2017. There are many causes of infertility, including some that medical intervention can treat. Estimates from 1997 suggest that worldwide about five percent of all heterosexual couples have an unresolved problem with infertility. Many more couples, however, experience involu ...

Erythrina Caffra
''Erythrina caffra'', the coast coral tree or African coral tree, is a tree native to southeastern Africa, which is often cultivated and has introduced populations in California and India. All the 17 species of coral tree in the genus ''Erythrina'' are collectively considered the official tree of Los Angeles, California in the United States. Description ''Erythrina caffra'' is a medium to large deciduous tree. It grows in coastal bushes and riverine forests along the south eastern coast of South Africa and up into Zululand. Leaves The compound leaves are made up of three leaflets. Each leaflet is broadly ovate to elliptical. The leaflets do not have prickles and are hairless. Flowers The flowers are made up of a main petal and four small petals. The main petal curves back to expose the stamens. The flower colour is warm red to scarlet. This is one of the main differences between ''Erythrina caffra'' and '' Erythrina lysistemon''. The flowers form stalked axillary racemes u ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Pied Starling (Sturnus Contra) Feeding On Indian Coral Tree (Erythrina Variegata) In Kolkata I IMG 4005
The Indian pied myna (''Gracupica contra'') is a species of starling found in the Indian subcontinent. It is usually found in small groups mainly on the plains and low foothills. It is often seen within cities and villages although it is not as bold as the common myna. It produces a range of calls made up of liquid notes. Taxonomy The Indian pied myna was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Sturnus contra''. Linnaeus based his description on the "Contra, from Bengall" that had been described and illustrated in 1738 by Eleazar Albin and the "Black and White Indian Starling" that had been described and illustrated in 1751 by George Edwards. Albin believed that "contra" was the Bengali word for this species, but this name was not known in the 19th century. Linnaeus specified the type locality as India but this was restricted to Calcutta by the British ornithologist E. C. Stua ...

Kerala
Kerala ( ; ) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of Cochin, Malabar, South Canara, and Thiruvithamkoor. Spread over , Kerala is the 21st largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33 million inhabitants as per the 2011 census, Kerala is the 13th-largest Indian state by population. It is divided into 14 districts with the capital being Thiruvananthapuram. Malayalam is the most widely spoken language and is also the official language of the state. The Chera dynasty was the first prominent kingdom based in Kerala. The Ay kingdom in the deep south and the Ezhimala kingdom in the north formed the other kingdoms in the early years of the Common Era (CE). The region had been a prominent spic ...

Afrikaans
Afrikaans (, ) is a West Germanic language that evolved in the Dutch Cape Colony from the Dutch vernacular of Holland proper (i.e., the Hollandic dialect) used by Dutch, French, and German settlers and their enslaved people. Afrikaans gradually began to develop distinguishing characteristics during the course of the 18th century. Now spoken in South Africa, Namibia and (to a lesser extent) Botswana, Zambia, and Zimbabwe, estimates circa 2010 of the total number of Afrikaans speakers range between 15 and 23 million. Most linguists consider Afrikaans to be a partly creole language. An estimated 90 to 95% of the vocabulary is of Dutch origin with adopted words from other languages including German and the Khoisan languages of Southern Africa. Differences with Dutch include a more analytic-type morphology and grammar, and some pronunciations. There is a large degree of mutual intelligibility between the two languages, especially in written form. About 13.5% of the South ...
