Special Issue Information

Dear Colleagues,

Decapod crustaceans have successfully colonized a wide range of habitats in freshwaters all around the world, becoming a key component of these ecosystems. The estimated numbers of species are 1300 for primary freshwater crabs (Brachyura), 2500 for freshwater anomurans (Aeglidae), 800 for freshwater shrimps (Caridea) and 590 for crayfish (Astacidea). This great taxonomic diversity reflects the diversity of habitats occupied by freshwater decapods, from the lower reaches of rivers to mountain streams through lakes, temporary ponds or underground water bodies. Despite generating a steady interest from scientists for decades, the recent developments of new tools applied to their study led to an increase in the number of new species descriptions, and more and more phylogenies have been published, shedding new light on the evolution of freshwater decapod crustaceans. However, the majority of taxa remains to be discovered regarding the evolutionary history of these taxa, and new species descriptions are still frequent among them. Therefore, this Special Issue will focus on the taxonomy, systematics, evolution and biogeography of freshwater decapod crustaceans.

The scope includes but is not limited to the following fields: taxonomy, phylogeny, evolutionary history, phylogeography and palaeontology. If you are interested in this opportunity or have any questions, please do not hesitate to contact us.

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 2600 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Four new species of freshwater crab are described from material collected in northern and southwestern Cameroon and assigned to Sudanonautes Bott, 1955. Sudanonautes cameroonensis sp. n., S. eyimba sp. n., S. ngaoundere sp. n. and S. nkam sp. n., are distinguished by characters of the carapace, thoracic sternum, chelipeds, mandibles, adult male gonopods, and in addition by genetic analyses using the mitochondrial CO1 and 16S rRNA genes. Diagnoses, illustrations, and a phylogenetic tree based on mtDNA sequences are provided, as well as a discussion of the threats and conservation of all species. Full article

Abstract
Twelve species of atyid shrimps are reported from three Micronesian islands (Babeldaob, Pohnpei, and Guam) and studied using a combined morphological and molecular approach. Among them, three are new records for the area (Caridina appendiculata, Caridina lobocensis, and Caridina rubella [...] Read more.
Twelve species of atyid shrimps are reported from three Micronesian islands (Babeldaob, Pohnpei, and Guam) and studied using a combined morphological and molecular approach. Among them, three are new records for the area (Caridina appendiculata, Caridina lobocensis, and Caridina rubella), while three new species are here described: Atyoida chacei sp. nov., Caridina ponapensis sp. nov., and Caridina rintelenorum sp. nov. Descriptions for these new species, diagnoses for poorly known species, and taxonomic notes are provided herein and their biogeography is discussed. Full article

Biological invasions pose significant challenges in the Anthropocene, impacting ecosystem biodiversity and functioning. Ecological Niche Modeling is widely used to evaluate potential areas at risk of invasions, aiding in the prevention of invasive-species expansion and guiding conservation efforts in freshwater ecosystems. The main objectives of this study were to model the ecological niche and evaluate remaining suitable habitat areas for the occurrence of five potentially invasive species of freshwater decapods in South America: Dilocarcinus pagei, Macrobrachium amazonicum, M. jelskii, M. rosenbergii, and Procambarus clarkii. Occurrence data from the Global Biodiversity Information Facility were complemented with a literature systematic review. Variables used in the models were obtained from the Worldclim and EarthEv databases. Ecological Niche Modeling was performed using the Biomod2 and sdm package algorithms. Our results indicated a suitable area of up to 11% of South America. Model evaluations yielded favorable TSS and AUC values (>0.7 and >0.8). The suitable areas projected for South America included several hydrographic basins and Protected Areas. The information generated in our study can help identifying areas susceptible to decapod invasion in South America and support local management and decisions. Full article
