Waggle Dance
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations with other members of the colony. The waggle dance and the round dance are two forms of dance behaviour that are part of a continuous transition. As the distance between the resource and the hive increases, the round dance transforms into variations of a transitional dance, which, when communicating resources at even greater distances, becomes the waggle dance. In the case of ''Apis mellifera ligustica'', the round dance is performed until the resource is about 10 metres away from the hive, transitional dances are performed when the resource is at a distance of 20 to 30 metres away from the hive, and finally, when it is located at distances greater than 40 metres from the hive ...

Black Dwarf Honeybee
''Apis andreniformis'', or the black dwarf honey bee, is a relatively rare species of honey bee whose native habitat is the tropical and subtropical regions of Southeast Asia. ''A. andreniformis'' was the fifth honey bee species to be described of the seven known species of '' Apis''. Until recently, however, the actual identity of the species was poorly understood. It was not recognized as its own species, but was instead considered to be a part of the species ''Apis florea.'' Recent studies have highlighted notable differences between the bees and have thus separated them into distinct species. Taxonomy and phylogeny ''Apis andreniformis'' is a part of the family Apidae, which includes honey, cuckoo, carpenter, digger, bumble, and stingless bees. The genus ''Apis'' includes honey bees, the most common being ''Apis mellifera'', otherwise known as the Western honey bee. ''A. andreniformis'' is most closely related to ''Apis florea'', its sister species with which it is common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand De Saussure
Ferdinand de Saussure (; ; 26 November 1857 – 22 February 1913) was a Swiss linguist, semiotician and philosopher. His ideas laid a foundation for many significant developments in both linguistics and semiotics in the 20th century. He is widely considered one of the founders of 20th-century linguistics and one of two major founders (together with Charles Sanders Peirce) of semiotics, or ''semiology'', as Saussure called it. One of his translators, Roy Harris, summarized Saussure's contribution to linguistics and the study of "the whole range of human sciences. It is particularly marked in linguistics, philosophy, psychoanalysis, psychology, sociology and anthropology." Although they have undergone extension and critique over time, the dimensions of organization introduced by Saussure continue to inform contemporary approaches to the phenomenon of language. As Leonard Bloomfield stated after reviewing the ''Cours'': "he has given us the theoretical basis for a science of human s ...
