Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Anyphaenidae
Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have eight eyes arranged in two rows, conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 500 species in over 50 genera worldwide. The family is widespread and includes such common genera as ''Anyphaena'' (worldwide except tropical Africa and Asia) and ''Hibana'' (New World). Only one species ('' A. accentuata'') occurs in northwestern Europe. Species in the latter genus are important predators in several agricultural sys ...

Frederick Octavius Pickard-Cambridge
Frederick Octavius Pickard-Cambridge (3 November 1860 – 9 February 1905) was an English arachnologist. He is sometimes confused with his uncle, Octavius Pickard-Cambridge (1828–1917), who was also an arachnologist and from whom F. O. Pickard-Cambridge picked up his enthusiasm for the study of spiders. Life F. O. Pickard-Cambridge was born in Warmwell, Dorset, where his father was rector. He became a curate at St Cuthbert's church in Carlisle for a few years after having been educated at Sherborne School and Exeter College, Oxford. He left to become a professional biological illustrator, and in 1894–1895 spent several months in the Amazon as a naturalist on board the SS ''Faraday''. He found much of interest on his voyage and began writing papers in 1896 to describe the spiders he discovered. He had a promising career ahead of him, but this promise was not to be fulfilled. Bristowe, writing in the book ''British Spiders'', 1951, said of this time in F. O. Pic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
