Posterior probability of new speciesNumber of speciesBy using a model of Hill for sampling from a finite population, the posterior moments of the number of species in the population and the posterior probability of finding a new species are obtained. Results are based on a negative binomial ...
►Speciation is the process by which new species form. It begins with the isolation of two populations. If two populations are to become sufficiently distinct that interbreeding is difficult or impossible, then there must be relatively little gene flow (migration) between them (because if there ...
The vast majority of newly discovered species fall into a small number of known supergroups. Recently, however, a handful of species with no clear relationship to other supergroups have been described2,3,4, raising questions about the nature and degree of undiscovered diversity, and exposing the...
Construction of a name 3.23 A species name shall consist of as few words as practicable but be distinct from names of other taxa. Species names shall not consist only of a host name and the word “virus”.Comments:Species names normally comprise more than one word. The styles used when vi...

(because if there were a great deal of gene flow, then genetic changes in one population would soon become widespread in the other as well). However, it is not enough for the two populations to simply be isolated; they will become separate species only if, during the period of isolation,...
sampling taxa by their species richness at the family level. Our analyses of wild, non-provisioned populations representing >400 species indicate that although males tend to be larger than females when dimorphism occurs, males are not larger in most mammal species, suggesting a need to revisit ot...
(He later licensed the compound to the AIDS Research Alliance of America, but it was never developed into a drug.) He also brokered a deal that helped save 30,000 acres of Samoan rain forest—home to many native species, including Pteropus samoensis, a flying fox, or genus of bat, ...
Light is a form of energy, a shock wave, that travels through the matrix of space. Its speed is determined by the dielectric properties of space. When that wave of energy arrives at its destination and hits an obstacle, an atmosphere lets say or something more solid, it converts or rathe...
