Special Issue Information

Dear Colleagues,

Circadian Rhythms Regulation in Aquatic Animals" is a new Special Issue that aims to explore the fascinating world of circadian rhythms in aquatic organisms. The rhythmic nature of life on Earth, driven by environmental cycles, has fostered the evolution of biological clocks in a wide range of aquatic animals, from microscopic plankton to marine mammals. These circadian clocks play a crucial role in modulating various physiological processes, behaviors, and interactions with the environment. Despite their importance, the circadian rhythms of aquatic animals have not received as much attention as those of terrestrial organisms. This Special Issue seeks to bridge this gap by inviting researchers to contribute original research articles, reviews, and other accepted article types that uncover the mechanisms and functional significance of circadian rhythms in aquatic animals. The issue will explore topics such as the entrainment mechanisms, molecular clockwork, interplay between circadian rhythms and environmental factors, and the implications of circadian dysregulation on the health and ecology of aquatic species. By shedding light on the temporal organization of aquatic life, this Special Issue will provide valuable insights into the impact of circadian rhythms on the biology and ecology of aquatic animals.

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. Life 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 2600 CHF (Swiss Francs).

Light is an indispensable factor in the healthy growth of living organisms, and alterations in the photoperiod can have consequences for body homeostasis. The eyestalk is a photosensitive organ that secretes various hormones to regulate the Chinese mitten crab (Eriocheir sinensis). However, the photoperiod-dependent eyestalk patterns of gene expression that may underlie changes in body homeostasis are unknown. In this study, we investigated the molecular mechanisms involved in eyestalk transcriptomic responses in E. sinensis under different photoperiod regimes on days 2, 4, and 6. The photoperiods tested were 12, 24, and 0 h light/day. In total, we obtained 110, 958, 348 clean datasets and detected 1809 differentially expressed genes (DEGs). Genes involved in the crustacean hyperglycemic hormone superfamily and juvenile hormones were observed, which play important roles in gonadal development, growth, and immunity in E. sinensis and may also be involved in photoperiod adaptation. In addition, the MAPK signaling pathway was the only signaling pathway identified in the continuous light group but was absent in the continuous darkness group. We suggest that the MAPK pathway is highly responsive to light input during the subjective night and insensitive to light during the middle of the subjective day. These results provide insight into the molecular mechanisms underlying the effects of photoperiod on the immune regulation of E. sinensis. Full article
