Euglossa Cordata
''Euglossa cordata'' is a primitively eusocial orchid bee of the American tropics. The species is known for its green body color and ability to fly distances of over 50 km. Males mostly disperse and leave their home nests, while females have been observed to possess philopatric behavior. Because of this, sightings are rare and little is known about the species. However, it has been observed that adults who pollinate certain species of orchids will become intoxicated during the pollination. Taxonomy and phylogeny ''Euglossa cordata'' is a member of the genus ''Euglossa'' in the tribe Euglossini within subfamily Apinae of the hymenopteran family Apidae. ''Euglossini'' pollinate throughout the American tropics, and are known for their bright, metallic appearance. ''Euglossini'' is one of four tribes of the family Apinae, along with Meliponini (stingless bees), Bombini (bumble bees), and Apini (honey bees). There are five genera of Euglossini: ''Algae'', ''Exaerete'', ''Eufries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eusociality
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the ...

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Totipotent
Pluripotency: These are the cells that can generate into any of the three Germ layers which imply Endodermal, Mesodermal, and Ectodermal cells except tissues like the placenta. According to Latin terms, Pluripotentia means the ability for many things. We can generate Induced Pluripotent cells by using the Induced pluripotency technique by triggering or expressing the genes or the transcription factors of the normal somatic cells. They are abbreviated as iPSC or IPS. We can forcefully express the transcription factors like Oct4, Sox2, Klf4, and c-Myc of a non-pluripotent cell and convert them into a stem cell. This procedure is first studied in a Mouse fibroblast cell in 2006 and followed the same instructions in developing a Human pluripotent cell from a Human epidermal fibroblast cell. The technique is called Regeneration. Though the iPSC has similar properties to embryonic stem cells they were never approved for clinical stage research because they are highly Tumerogenic, hav ...

Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embr ...

Corolla (flower)
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coryanthes Speciosa
''Coryanthes speciosa'', the bat orchid, is a species of orchid found in Brazil, Colombia, Costa Rica, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Suriname, Venezuela, the Caribbean and Belize. As noted by the position of the "bucket", liquid drops in from above by a special stem gland. The bucket fills, nectar drinking organisms such as bees are attracted to the sweet drops forming above the bucket. As the bees jostle for position, some bees inadvertently fall into the bucket. The bucket's fluid levels are regulated by a spout that allows overflowing liquid to be released. This is the only escape for the drowning bees. Whilst traveling through the spout, the anther's of the plant produce pollen that then sticks to the escaping bee. Positioned perfectly at the end of the spout lies the stigma that must be crossed by the frantic bee. Pollination is then assured, the bee is free to try its luck on other plants nearby. Thus, even cross polli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stanhopeinae
Stanhopeinae is a subtribe of plants in the tribe Cymbidieae. The subtribe in the strict sense, have viscidia and stipes that are thin and strap-like, they are adapted for attachment to edge of the bee's scutellum or to a leg. Pseudobulbs are usually ribbed/four-angled or flattened. Leaves are generally thicker than Coeliopsidinae. Roots are smooth, without prominent root hairs. The column foot is lacking or not distinct. Unpollinated flowers quickly abscise and fall from the inflorescence, unlike members of Coeliopsidinae which include ''Coeliopsis'', '' Lycomormium'', and '' Peristeria''. Stanhopeinae and Coeliopsidinae are now considered closely related sister subtribes. Within Stanhopeinae the members can be further grouped in six clades based on morphological traits and molecular analysis. *''Braemia'' Clade: '' Braemia'' *''Gongora'' Clade: ''Cirrhaea'' & '' Gongora'' *''Acineta'' Clade: ''Acineta'', '' Lacaena'', ''Lueddemannia'' & ''Vasqueziella'' *''Polycycnis'' Clade: ...
