Sentence examples for facultative use from inspiring English sources

The data suggest a facultative use of different combinations of factors.

Because acoustic signaling in small animals like insects is energetically demanding (mainly due to the low efficiency with which metabolic energy is converted to acoustic power [50], [51], the difference in the energetic costs of calling and tremulation could play a role in a decision for the facultative use of one or the other of these signals.

A tight regulation of the facultative use of symmetric versus asymmetric divisions by stem cells is crucial for maintaining self-renewal capacity.

The absence of "facultative use of the primary host" constitutes a strong argument in favour of the fundatrix specialisation hypothesis, suggesting that host alternation loss involves a loss of the primary host, but not of the secondary host.

Even with the use of several variable DNA markers (Buchnera intergenic regions), it was not possible to differentiate specimens into these species: this complex of taxa ("subspecies" or "biotypes") may therefore constitute a case of a heteroecious species making facultative use of the primary host for the sexual phase.

Many facultative anaerobes use bo and bo3 oxidases which use quinol as the substrate instead of cyts c.

We test for evidence of local adaptation or facultative spawning using a common garden experiment (CGE) design.

The goal of this study was to harness the redox gradients in facultative lagoons using a lagoon microbial fuel cell (LMFC) to enhance autonomously the delivery of oxygen to the lagoon through aeration and mixing by operating an air pump.

FeRB can be either strict anaerobes (eg members of the Geobacteraceae) or facultative anaerobes that use oxygen, but can switch to using iron as a terminal electron acceptor under anaerobiosis (eg members of the genus Shewanella).

Fructose 1-phosphate is also formed when facultative anaerobic microorganisms use fructose as a carbon source for growth; in this case, however, the source of the phosphate is phosphoenolpyruvate rather than ATP.

We verified that all experimental aphid lines used in this study were free of facultative symbionts by using 1) diagnostic PCR to screen for all known pea aphid facultative symbionts, 2) 'mostly universal' PCR primers that amplify most bacteria, but not the obligate symbiont Buchnera, and 3) Denaturing Gradient Gel Electrophoresis (DGGE) with universal 16S rRNA bacterial primers.
