Bombus Dahlbomii
''Bombus dahlbomii'', also known as the moscardón, is a species of bumblebee endemism, endemic to southern South American temperate forests. ''B. dahlbomii'' is one of the largest bee species in the world, with matured queens growing up to long.King, A. (September 14, 2012Plight of the Bumblebee.''ScienceNow''. Because of its size and furry appearance, the species has been described as "flying mice" colloquially, and "a monstrous fluffy ginger beast" by British ecologist Dave Goulson, David Goulson. ''B. dahlbomii'' is native to southern Chile and southern Argentina, including Patagonia. The decline of its populations started with the introduction of ''Bombus terrestris'' and ''Large garden bumblebee, B. ruderatus'' into Chile to serve as commercial pollinators. ''B. dahlbomii'' population decline can also be attributed to the pathogen spillover of the parasitism, parasitic protozoan ''Apicystis bombi'', which was co-introduced with ''B. terrestris''.

Félix Édouard Guérin-Méneville
Félix Édouard Guérin-Méneville, also known as F. E. Guerin, (12 October 1799, in Toulon – 26 January 1874, in Paris) was a French entomologist. Life and work Guérin-Méneville changed his surname from Guérin in 1836. He was the author of the illustrated work ''Iconographie du Règne Animal de G. Cuvier 1829–1844'', a complement to the work of the zoologists Georges Cuvier and Pierre André Latreille, ''Le Règne Animal'', which illustrated only a selection of the animals covered. Cuvier was delighted with the work, saying that it would be very useful to readers, and that the illustrations were "as accurate as they were elegant". He also introduced silkworms to France, so they could be bred for the production of silk. Guérin-Méneville founded several journals: ''Magasin de zoologie, d’anatomie comparée et de paléontologie'' (1830), ''Revue zoologique par la Société cuviérienne'' (1838), ''Revue et Magasin de zoologie pure et appliquée'' (1849), and ''Revue de ...

30th Parallel South
Following are circles of latitude between the 25th parallel south and the 30th parallel south: 26th parallel south The 26th parallel south latitude is a circle of latitude that is 26 degrees south of Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Australia, the Pacific Ocean and South America. Australia In Australia, the northernmost border of South Australia, and the southernmost border of the Northern Territory are defined by 26° south. Additionally, 26° south also defines an approximately 127 metre section of the Western Australia/Northern Territory border at Surveyor Generals Corner due to inaccuracies in the 1920s for fixing positions under constraints of available technology. The parallel also defines part of the Queensland and South Australia border between the 138th and 141st meridians east. Around the world Starting at the Prime Meridian and heading eastwards, the parallel 26° south passes through: : 27th parallel sout ...

Protozoan
Protozoa (: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. Historically, protozoans were regarded as "one-celled animals". When first introduced by Georg Goldfuss, in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. This classification remained widespread in the 19th and early 20th century, and even became elevated to a variety of higher ranks, including phylum, subkingdom, kingdom, and then sometimes included within the paraphyletic Protoctista or Protista. By the 1970s, it became usual to require that all taxa be monophyletic (derived from a common ancestor that would also be regarded as protozo ...

Polylectic
The term polylecty or generalist is used in pollination ecology to refer to bees that collect pollen from a range of unrelated plants. Apis (genus) , Honey bees exemplify this behavior, collecting nectar from a wide array of flowers. Other predominantly polylectic genera include Bombus, Ceratina, Heriades and Halictus. The opposite term is oligolecty, and refers to bees that exhibit a narrow, specialized preference for pollen sources, typically to a single family or genus of flowering plants. Roughly two-thirds of bee species in Europe are polylectic, relying on a diverse array of pollen sources. This broad foraging approach allows these generalist bees to thrive in various environments and quickly adjust to shifting conditions. However, despite their adaptability, they are less efficient pollen gatherers than oligolectic bees, whose insect morphology , morphology is often specialized for more effective pollen collection from a narrower range of plants.

Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphology (biology), morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other Hominini, hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival ...

Asteranthera Ovata
''Asteranthera'' is a monotypic plant genus in the family Gesneriaceae, native to the humid temperate forests of Argentina and Chile. The sole species in the genus, ''Asteranthera ovata'', is an evergreen scrambling vine A vine is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas, or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Da .... The plant has small rounded leaves with scalloped margins.

Crinodendron Hookerianum
''Crinodendron hookerianum'', known as the Chilean lantern tree, is an evergreen tree in the family Elaeocarpaceae. It is endemic to Chile, where it occurs from Cautin to Palena (38 to 43°S). It grows near streams and in very humid and shady places, and is often found in Valdivian temperate forests. Derivation of scientific name The Latin generic name ''Crinodendron'' is a compound of the Ancient Greek words κρίνον (krínon) "lily" and δένδρον (dendrón) "tree", the "lily" element being inspired by the white-flowered '' C. patagua''. The specific name ''hookerianum'' honours William Jackson Hooker, an English botanist who studied many Chilean plants. The genus ''Crinodendron'' is a small one, containing only four species, the other two (not generally cultivated in the United Kingdom) being '' C. tucumanum'' Lillo, a 25m tree native to Argentina, and the Brazilian '' C. brasiliense'' Reitz & L.B.sm.

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
