Special Issue Information

Dear Colleagues,

Deep-sea hydrothermal vents represent some of the most extreme and fascinating ecosystems on Earth. These unique environmental features, characterized by their high temperatures and the presence of mineral-rich fluids, create a variety of habitats that support a diverse array of microbial and faunal life, as well as complex biological ecosystems. The biological geography of these ecosystems is complex and intriguing, offering a wealth of opportunities for scientific exploration and understanding. Here, we call for a Special Issue to provide an academically inclusive platform for open discussions among scholars. In this Special Issue, we welcome original research articles and reviews with a suggested minimum word count of 4000 words. Additionally, scoping review-type articles can be submitted as review articles.

Research will cover a broad spectrum of topics related to deep-sea hydrothermal vents, including, but not limited to, the following: the spatial and/or temporal variations in hydrothermal ecosystems, as well as the underlying physical, geological, and chemical processes; the diversity of microbial communities that thrive in these extreme environments, including their metabolic pathways and adaptations; the diversity and biogeography of vent fauna that fill a gap in understanding their distribution pattern on a large scale; the symbiotic relationships between vent-dwelling organisms and the microbes that support them; the role of hydrothermal vents in the broader context of marine biodiversity and ecosystem services; and technological advancements in the exploration and study of deep-sea hydrothermal vent ecosystems. In addition, we also welcome scholars to submit other articles related to the above themes. We sincerely invite you to contribute to the development of an academic subject in this field, and hereby extend our highest respect.

We are looking forward to your contributions.

Manuscripts should be submitted online at www.mdpi.com 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. Biology is an international peer-reviewed open access monthly 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 2700 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.

Organisms occupy diverse ecological niches worldwide, each with characteristics finely evolved for their environments. Crustaceans residing in deep-sea hydrothermal vents, recognized as one of Earth’s extreme environments, may have adapted to withstand severe conditions, including elevated temperatures and pressure. This study compares the exoskeletons of two vent crustaceans (bythograeid crab Austinograea sp. and squat lobster Munidopsis lauensis) with four coastal species (Asian paddle crabs, blue crab, hermit crab, and mantis shrimp) to identify traits influenced by vent environments. The goal was to identify distinctive exoskeletal characteristics commonly observed in vent crustaceans, resulting from their exposure to severe abiotic factors, including elevated temperatures and pressures, found in vent environments. Results show that the exoskeletons of vent crustaceans demonstrated significantly enhanced thermal stability compared to coastal species. These vent crustaceans consistently featured exoskeletons characterized by a reduced proportion of volatile components, such as water, and an increased proportion of CaCO3, compared with coastal crustaceans. Furthermore, vent crustaceans lacked carotenoid pigments that had low heat resistance. However, no apparent differences were observed in the mechanical properties. Our findings suggest that the similar composition of exoskeletons in vent crustaceans evolved convergently to withstand high temperatures. Full article
