Alocandrena
The bee subfamily Alocandreninae contains only one genus and one species, ''Alocandrena porteri'', which is found in Peru Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pac .... It seems to be restricted to the western side of the Andes Mountains. It has been recorded throughout the year, suggesting multiple generations per year.

Andrenidae
The Andrenidae (commonly known as mining bees) are a large, nearly cosmopolitan distribution, cosmopolitan family of solitary, ground-nesting bees. Most of the family's diversity is located in temperate or arid areas (warm temperate xeric). It includes some enormous genera (e.g., ''Andrena'' with over 1300 species, and ''Perdita (bee), Perdita'' with over 700). One of the subfamilies, Oxaeinae, is so different in appearance that they were typically accorded family status, but careful phylogenetic analysis reveals them to be an offshoot within the Andrenidae, very close to the Andreninae.C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. Description The Andrenidae are typically small to moderate-sized bees, which often have scopa (biology), scopae on the basal segments of the leg in addition to the arthropod leg, tibia, and are commonly oligolectic (especially within the subfamily Panurginae). They can be separated from other bee familie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peru
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pacific Ocean. Peru is a Megadiverse countries, megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has Demographics of Peru, a population of over 32 million, and its capital and largest city is Lima.

Lycopersicon
''Lycopersicon'' was a genus in the flowering plant family Solanaceae (the nightshades and relatives). It contained about 13 species in the tomato group of nightshades. First removed from the genus ''Solanum'' by Philip Miller in 1754, its removal leaves the latter genus paraphyletic, so modern botanists generally accept the names in ''Solanum''. The name ''Lycopersicon'' (from Greek ''λυκοπέρσικον'' meaning "wolf peach") is still used by gardeners, farmers, and seed companies. Collectively, the species in this group apart from the common cultivated plant are called wild tomatoes. Cladistic analysis of DNA sequence data confirms ''Lycopersicon'' as a clade that is part of a lineage of nightshades also including the potato (''S. tuberosum''). If it is desired to continue use of ''Lycopersicon'', it can be held as a section inside the potato-tomato subgenus whose name has to be determined in accordance with the ICBN.Solanaceae Source 008br>Phylogeny Retrieved 2008-OCT-0 ...

Monotypic Bee Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Taxa Named By Charles Duncan Michener
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Andes
The fauna of the Andes, a mountain range in South America, is large and diverse. As well as a huge variety of flora, the Andes contain many different animal species. With almost 1,000 species, of which roughly 2/3 are endemism, endemic to the region, the Andes are the most important region in the world for amphibians.Tropical Andes - biodiversityhotspots.org The diversity of animals in the Andes is high, with almost 600 species of mammals (13% endemic), more than 1,700 species of birds (about 1/3 endemic), more than 600 species of reptiles (about 45% endemic), and almost 400 species of fish (about 1/3 endemic).
