Diversity and Ecology of Decapoda

Dear Colleagues,

The order Decapoda encompasses a remarkable diversity of crustaceans, including crabs, lobsters, shrimps, and related groups, which occupy an extensive range of marine, freshwater, and even semi-terrestrial environments. This diversity is reflected not only in their morphological and functional traits but also in their evolutionary patterns and ecological roles across ecosystems.

From an ecological perspective, decapods are essential components of aquatic ecosystems. They act as predators, prey, detritivores, and ecosystem engineers, influencing food webs, shaping benthic communities, and contributing to nutrient cycling. Their ecological roles, combined with their global distribution, highlight their importance not only for ecosystem functioning, but also for human societies, particularly through fisheries, aquaculture, and cultural value.

Nevertheless, there is still a significant lack of information regarding the diversity and distribution of decapod species in many geographic regions, especially in areas where systematic surveys and long-term monitoring remain scarce. Filling these knowledge gaps is crucial to better understanding patterns of biodiversity, species endemism, and ecological resilience.

Despite their importance, many decapod populations are increasingly threatened by climate change, habitat degradation, overfishing, and invasive species. Understanding the interplay between their biodiversity, ecological functions, and geographic distribution is therefore fundamental for developing conservation strategies and promoting sustainable resource management.

This Special Issue, “Diversity and Ecology of Decapoda”, aims to provide a comprehensive platform for exploring current research and new perspectives on this group. We encourage submissions on taxonomy, systematics, population dynamics, trophic ecology, functional morphology, biogeography, conservation biology, and applied studies that contribute to advancing our understanding of decapod diversity and their ecological significance.

Manuscript Submission Information

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. Diversity 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 2100 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.
