Sentence examples for needed for speciation from inspiring English sources

This is in line with the Pleistocene speciation hypothesis invoking that much longer periods of time in isolation are needed for speciation to occur.

The Mycofast Revolution assay does not distinguish between the species, U. parvum and U. urealyticum and analysis with additional molecular methods is needed for speciation.

For example, differences in abundance of pollinators across the landscape might drive the initial divergence needed for speciation [ 5, 6], and classic studies on Mimulus[ 21] support this as a likely mechanism.

For a better understanding of the actinide behaviour in man (in term of metabolism, retention, excretion) and in specific biological systems (organs, cells or biochemical pathways), it is of prime importance to have a good knowledge of the relevant actinide solution chemistry and biochemistry, in particular of the thermodynamic constants needed for computing actinide speciation.

This emphasizes the need for speciation and determination of susceptibility pattern of the Candida isolates from HIV patients with oropharyngeal candidiasis.

The speed at which this process happens is still intriguing and controversial [ 2] but estimates of speciation rates generally show that 10 107 years (yrs) are needed for new species to evolve [ 3].

An understanding of the pattern of host-virus cospeciation, or cophylogeny (see [ 9, 10]) is needed for comparing evolutionary rates based on molecular divergences (e.g. [ 11]), because it relies on the assumption of simultaneous speciation.

Although Howard[31] proposed possible reaction mechanisms for the formation of ferroselite in a pyrite environment, the actual reactions occurring in the environment are not known; highlighting the need for accurate speciation studies.

The objectives of this study were to determine the status of state surveillance for bat-associated rabies at the species level, assess the comparative characteristics of the antigenic and genetic variants of rabies in bats in Texas, and examine the need for bat speciation and genetic variant determination in assigning uniform variants of RABV.

To this end, reliable experimental data are needed including quantitative speciation to assist further development of reaction mechanisms and their reduction for practical applications.

A number of conditions need to be met for speciation via host-shift to occur, such as evolution of assortative mating and selection against hybrids, but if these are fulfilled, speciation can be rapid.
