Special Issue Information

Geobiology is the study of how living organisms interact with and affect their environment over time. One key aspect of this field is understanding the ways in which metabolic diversity among different organisms can influence the environment. Metabolic diversity refers to the range of different ways that organisms can convert energy and nutrients into the building blocks they need to survive and reproduce. For example, some organisms are photosynthetic, meaning they use light energy to convert carbon dioxide and water into organic compounds that they can use for energy. These organisms can have a profound impact on the environment, as they release oxygen as a by-product of their metabolic processes, which has helped to create the oxygen-rich atmosphere we breathe today. Other organisms are chemosynthetic, meaning they obtain energy by oxidizing inorganic compounds, such as hydrogen sulfide, methane, or ammonia. These organisms are typically found in extreme environments, such as deep-sea hydrothermal vents or the guts of some animals. They can also have an impact on their environment, as they can produce or consume these inorganic compounds, which can have ripple effects throughout an ecosystem. Metabolic diversity also plays a role in the carbon cycle and other biogeochemical cycles. For example, some microorganisms can break down complex organic molecules, such as lignin and cellulose, which are resistant to degradation by other organisms. This helps to release carbon back into the ecosystem, which can then be used by other organisms. Other microorganisms play a role in nitrogen fixation, converting atmospheric nitrogen into forms that can be used by plants and other organisms. Overall, understanding the role of metabolic diversity in geobiology can help us to better understand how living organisms have shaped the environment over time, and how they will continue to do so in the future. This Special Issue solicits contributions from researchers working in a wide variety of fields, including Geobiology, Geomicrobiology, Geochemistry, Astrobiology, and Geology. Articles based on original research, shorter communications, and reviews are all encouraged to be submitted to this Special Issue. All submissions will be reviewed in a timely and rigorous manner, and accepted papers will be published online as soon as they are ready.

Manuscript Submission Information

Manuscripts should be submitted online at by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
