“…Metabarcoding was used to identify macrozooplankton, epipelagic mesozooplankton (0−200 m), and microbial communities (prokaryotes and microbial eukaryotes) (Supplementary Table 3 ). Specifically, DNA from macrozooplankton (crustacean, mollusks, and insects) was extracted as in Marco-Herrero et al 55 . Target mitochondrial DNA from the 16S rRNA and COI genes was amplified with polymerase chain reaction (PCR).…”

Global patterns of planktonic diversity are mainly determined by the dispersal of propagules with ocean currents. However, the role that abundance and body size play in determining spatial patterns of diversity remains unclear. Here we analyse spatial community structure - β-diversity - for several planktonic and nektonic organisms from prokaryotes to small mesopelagic fishes collected during the Malaspina 2010 Expedition. β-diversity was compared to surface ocean transit times derived from a global circulation model, revealing a significant negative relationship that is stronger than environmental differences. Estimated dispersal scales for different groups show a negative correlation with body size, where less abundant large-bodied communities have significantly shorter dispersal scales and larger species spatial turnover rates than more abundant small-bodied plankton. Our results confirm that the dispersal scale of planktonic and micro-nektonic organisms is determined by local abundance, which scales with body size, ultimately setting global spatial patterns of diversity.

“…In this context, crustaceans, that represent one of the most diverse metazoan groups from a morphological and ecological point of view 9 with more than 67,000 described species so far 10 , are an interesting target taxon for DNA barcoding because they are not always easy to identify by traditional approaches and usually require the help of highly trained taxonomists 11 . One of the biggest problems is to identify the larval stages of this group, because the larvae are distinguishable but not easily matched with the correct adult form 12,13 . Therefore, this problem causes obstacles in studies such as plankton ecology or population connectivity 14,15 .…”

Megalopas of 15 brachyuran crab species collected in the open sea plankton, and unknown until now, were identified using DNA barcodes (COI and 16S rRNA). Specimens belonging to the families Portunidae, Pseudorhombilidae and Xanthidae (Crustacea, Decapoda, Brachyura), and corresponding to the species Achelous floridanus, Arenaeus mexicanus, Callinectes amnicola, C. arcuatus, C. ornatus, C. toxones, Charybdis (Charybdis) hellerii, Portunus hastatus, Thalamita admete, Scopolius nuttingi, Etisus odhneri, Liomera cinctimanus, Neoliomera cerasinus, Pseudoliomera variolosa, and Williamstimpsonia stimpsoni, are described and illustrated, and compared with other congeneric species previously described. We also provide a new geographical record for N. cerasinus and the most remarkable features for each species.

“…No 16S or COI sequences were obtained for this specimen. In Genbank, there are three sequences of 16S (KP057808, KP057811, and KP057812) and three sequences of COI (KP057815, KP057818, and KP057819) obtained by Marco-Herrero et al [109] for adults and larvae from the Mediterranean Sea.…”

The updated checklist of the marine crabs of Guinea-Bissau presented in this work is the result of consolidating decades of research, ongoing systematic revisions of the regional carcinofauna, and the inclusion of new records. DNA markers and morphological analyses for accurate identifications are integrated. Sixty-one species are mentioned in this list after reviewing specimens from scientific collections and literature. Of these 61 species listed, the presence of 51 species in Guinea-Bissau is confirmed, and 21 are reported for the first time in the area. A total of 98 sequences were obtained from 41 species (51 of 16S for 38 species and 47 of COI for 35 species), and 48 sequences (24 of 16S and 24 of COI) were the first ones obtained for 29 species. The maximum or minimum bathymetric range is expanded by 16 species, and for other six species, a color description is provided for the first time. Merocryptus obsoletus is synonymized as Merocryptus boletifer. The present study will be a useful baseline for gathering further ecological information about globally important marine taxa, not only in Guinea-Bissau but about African brachyurans in general.
