Wolbachia in arthropods has emerged as a conditional mutualist conferring advantages under certain environmental conditions.
However, under certain environmental conditions the cycle reaches epizootic proportions (affecting many animals in a region at the same time).
We have experienced ciguatera poisoning from being served fish that fed on the toxic dinoflagellates that produce this poison, and we have experienced the considerable discomfort of dengue fever (called bone-break fever for how it makes you feel), which is spread by mosquitoes under certain environmental conditions.
PLA corn based bottles are derived from an organic substance and are degradable under certain environmental conditions.
But under certain environmental conditions, diatoms may be scanty or absent in a particular water body, leading to a false negative diagnosis of drowning.
The unicellular cyanobacterium Synechocystis sp. strain PCC 6803 contains a single bidirectional NiFe-Hox-hydrogenase NiFe-Hox-hydrogenase NiFe-Hox-hydrogenaseironmental conditions.
One of the most important causes of paper degradation is biodeterioration, caused especially by fungi and bacteria under certain environmental conditions.
The comparison between fresh and aged depositions revealed that under certain environmental conditions an individual ridge could randomly change its original position regardless of its unaltered adjacent ridges.
Because biomarkers are derived from biological precursor molecules in specific organisms, and because each of these organisms lives only under certain environmental conditions, it is logical to use biomarkers as indicators of those conditions (Bjorøy et al. 1992).
Altogether, this report clearly demonstrates that biofilm formation of a given strain is highly dependent on experimental design and that specific mechanisms involved in biofilm formation such as fimbrial expression only play a role under certain environmental conditions.
While many organisms are competent only under certain environmental conditions, such as starvation, H. pylori is competent throughout logarithmic growth.
