As the largest environmental purifier on the earth, marine organisms are an essential part of the marine economy and play a vital role in regulating the stability and balance of marine ecosystems. Stimulated by changes in environmental factors, organisms make adaptive responses through their own internal mechanisms, so as to survive and reproduce. The long-term social activities of humans have exerted a series of impacts on ecosystems, such as global warming, marine and atmospheric pollution, red tides, and changes in the genetic diversity of organisms. These changes in environmental factors have imposed external stimuli and pressures on marine organisms, making it urgent to explore the mechanisms by which organisms respond to environmental changes. In particular, frequent maritime activities are causing increasingly serious marine pollution, exerting direct pressure on marine organisms. Therefore, it is highly necessary to clarify the interactive processes between the internal mechanisms of marine organisms and marine environmental factors.

The relationship between marine organisms and marine ecosystems has been studied, but the specific processes and mechanisms of interactions between them are rarely explored. In this context, molecular immunology, ecology, and bioinformatics can be employed to elucidate the adaptability and genetic and evolutionary diversity of marine organisms, their role in regulating the stability of the marine environment, and the potential mechanisms, processes, and methods underlying such role. Therefore, an important scientific basis can be laid for the alleviation of ecotoxicological risks, the protection of marine biological resources, the control of marine pollution, and the maintenance of the balance of marine ecosystems.

With the aid of molecular biology, bioinformatics, and ecological methods, this Research Topic intends to study the relationship between marine organisms and the marine ecological environment, in order to identify the specific mechanisms and processes underlying the mutual regulation effect between marine organisms and the ecological environment. It requires original and novel papers related to the adaptability of marine organisms and the regulation of the biological environment under any of the following research topics:

1. Adaptability of marine organisms to marine environmental pressure through their internal action mechanisms.
2. Ecotoxicological effects of marine pollution.
3. Studies on the mechanism of cell homeostasis maintenance during the environmental adaptation of organisms.
4. Effects of environmental change on marine biodiversity and distribution.
5. Relationship between changes in marine environmental factors and the evolution of immune genomes in marine organisms.
6. Changes in the structure of microbial communities, parasites, and environmental microbiotas in marine organisms.

Keywords: Marine organisms, ecology, environmental change, adaptability, diversity evolution, action mechanism
