Bombus Dahlbomii
''Bombus dahlbomii'', also known as the moscardón, is a species of bumblebee 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 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 '' B. ruderatus'' into Chile to serve as commercial pollinators. ''B. dahlbomii'' population decline can also be attributed to the pathogen spillover of the parasitic protozoan ''Apicystis bombi'', which was co-introduced with ''B. terrestris''. ''B. dahlbomii'' is an important insect in local ecosystems, such as the Maulino fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 silkworm The domestic silk moth (''Bombyx mori''), is an insect from the moth family Bombycidae. It is the closest relative of ''Bombyx mandarina'', the wild silk moth.

Bombus Ruderatus
''Bombus ruderatus'', the large garden bumblebee or ruderal bumblebee, is a species of long-tongued bumblebee found in Europe and in some parts of northern Africa. This species is the largest bumblebee in Britain and it uses its long face and tongue to pollinate hard-to-reach tubed flowers. Bumblebees are key pollinators in many agricultural ecosystems, which has led to ''B. ruderatus'' and other bumblebees being commercially bred and introduced into non-native countries, specifically New Zealand and Chile. Since its introduction in Chile, ''B. ruderatus'' has spread into Argentina as well. Population numbers have been declining and it has been placed on the Biodiversity Action Plan to help counteract these declines. Taxonomy and phylogeny ''Bombus ruderatus'' is part of the order Hymenoptera and the family Apidae. ''B. ruderatus'' is in the genus Bombus and is one of 239 species of bumblebees, with 23 of those existing in Britain alone. ''B. ruderatus'' is part of the subgenu ...

Sporozoites
Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism is typified by a ''cellular variety'' with a distinct morphology and biochemistry. Not all apicomplexa develop all the following cellular varieties and division methods. This presentation is intended as an outline of a hypothetical generalised apicomplexan organism. Methods of asexual replication Apicomplexans (sporozoans) replicate via ways of multiple fission (also known as schizogony). These ways include , and , although the latter is sometimes referred to as schizogony, despite its general meaning. Merogony is an asexually reproductive process of apicomplexa. After infecting a host cell, a trophozoite ( see glossary below) increases in size while repeatedly replicating its nucleus and other organelles. During this process, the orga ...

Protozoan
Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Historically, protozoans were regarded as "one-celled 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. When first introduced by Georg Goldfuss (originally spelled Goldfuß) in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals". In later classification schemes it was elevated to a variety of higher ranks, including phylum, subkingdom and kingdom, and sometimes included within Protoctista or Protista. The approach of classifying Protozoa within the context of Animalia was widespread in the 19th and early 20th century, but not universal. By the 1970s, it became usual to require ...

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 morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other 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 relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embothrium Coccineum
''Embothrium coccineum'', Chilean firetree or Chilean firebush, commonly known in Chile and Argentina as ''notro'', ''ciruelillo'' and ''fósforo'' is a small evergreen tree in the flowering plant family Proteaceae. It grows in the temperate forests of Chile and Argentina. Description The Chilean firetree grows 4–15 m (13–50 ft) tall and can reach 50 cm (20 in) in diameter.

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. Derivation of scientific name The Latin generic name ''Crinodendron'' is a compound of the Ancient Greek words κρίνον ("lily") and δένδρον ("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 U.K.) being ''C. tucumanum'' Lillo, a 25m tree native to Argentina, and the Brazilian ''C. brasiliense'' Reitz & L.B.sm. Common names in Chile The plant has several names, derived from the native language of the Mapuche people and colonial Spanish, the most common of ...

Eucryphia Cordifolia
''Eucryphia cordifolia'', the ulmo, is a species of tree in the family Cunoniaceae. It is found in Chile and Argentina. It is threatened by logging and habitat loss. The natural habitat is along the Andes Range from 38 to 43°S, and up to 700 meters (2300 ft) above sea level. It is a very elegant tree with a thick trunk and wide crown and can become over high. It blooms in February and March, depending on latitude and altitude. The fruit is a capsule about 1.5 cm (0.6 in) length. Cultivation and uses Its flowers contain a highly appreciated aromatic nectar, harvested by introduced European bees and commercialized as ulmo honey (''miel de Ulmo''). The wood is light brown to brown, heavy, moderately firm, rather hard and quite resistant to decay. It is used locally for construction and very extensively as firewood. It grows well on the western coast of Scotland, UK, where there are several notable specimens, including possibly the most northerly cultivate ...

Alstroemeria
''Alstroemeria'' (), commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America, although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centers of diversity; one in central Chile, the other in eastern Brazil. Species of ''Alstroemeria'' from Chile are winter-growing plants, while those of Brazil are summer growing. All are long-lived perennials except ''A. graminea'', a diminutive annual from the Atacama Desert of Chile. Description Plants of this genus grow from a cluster of tubers. They send up fertile and sterile stems, the fertile stems of some species reaching in height. The leaves are alternately arranged and resupinate, twisted on the petioles so that the undersides face up. The leaves are variable in shape and the blades have smooth edges ...

Lapageria
''Lapageria'' is a genus of flowering plants with only one known species, ''Lapageria rosea'', commonly known as Chilean bellflower or copihue (''copeewueh'', from Mapudungun ''kopiwe''). ''Lapageria rosea'' is the national flower of Chile. It grows in forests in the southern part of Chile, being part of the Valdivian temperate rain forests flora. Description ''Lapageria rosea'' is an evergreen climbing plant reaching over high among shrubs and trees. The leaves are arranged alternately and are evergreen, leathery, lanceolate and feature three to seven prominent parallel veins. The vines twine counterclockwise in the Southern hemisphere and clockwise when grown in the Northern hemisphere (likely due to the apparent motion of the sun). The flowers have six thick, waxy tepals which are red, spotted with white. They are most frequently produced in late summer and fall, although they may be produced at other times. The fruit is an elongated berry with a tough skin containing numer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
