The final two chapters review physiological and biochemical indicators of stress tolerance and breeding approaches to improving abiotic stress tolerance.
However, this technique only provides an external morphological description of putative fossilized cells and is incapable of distinguishing between abiotic fossils of similar morphologies.
Previous experimental results suggest the potential for abiotic organic synthesis under seafloor hydrothermal conditions.
However, these chemical species can be formed by abiotic geochemical processes.
Abiotic factors can significantly influence the abundance of gill monogeneans on fish.
The characterization of organic phases, from abiotic or biotic sources, also appears to be a fundamental issue.
Abiotic factors impose constraints on when, where and how ticks quest for hosts.
Laboratory experiments were conducted to evaluate the possibility that this process might also result in abiotic synthesis of hydrocarbons.
