Abstract Characterization of species diversity zooplankton is key to understanding, assessing, and predicting the function future pelagic ecosystems throughout global ocean. The marine assemblage, including only metazoans, highly diverse taxonomically complex, with an estimated ~28,000 41 major taxonomic groups. This review provides a comprehensive summary DNA sequences for barcode region mitochondrial cytochrome oxidase I (COI) identified specimens. foundation this MetaZooGene Barcode Atlas...
Tree of LifeMore than 2,500 species copepods (Class Maxillopoda; Subclass Copepoda) occur in the marine planktonic environment.The exceptional morphological conservation group, with numerous sibling groups, makes identification challenging, even for expert taxonomists.Molecular approaches to have allowed rapid detection, discrimination, and based on DNA sequencing single specimens environmental samples.Despite recent development diverse genetic genomic markers, barcode region mitochondrial...
Microbial associations that result in phytoplankton mortality are important for carbon transport the ocean. This includes parasitism, which microbial food webs is dominated by marine alveolate group, Syndiniales. Parasites expected to contribute recycling via host lysis; however, knowledge on dynamics and correlation export remain unclear limit inclusion of parasitism biogeochemical models. We analyzed a 4-year 18S rRNA gene metabarcoding dataset (2016-19), performing network analysis 12...
Abstract For the first time, phylogenetic relationships between representatives of all 10 copepod orders have been investigated using 28S and 18S rRNA, Histone H3 protein COI mtDNA. The monophyly Copepoda (including Platycopioida Fosshagen, 1985) is demonstrated for time molecular data. Maxillopoda rejected, as it a polyphyletic group. major subgroups Copepoda, including Progymnoplea Lang, 1948 (=Platycopioida); Neocopepoda Huys Boxshall, 1991; Gymnoplea Giesbrecht, 1892 (=Calanoida Sars,...
Detection of population genetic structure zooplankton at medium-to-small spatial scales in the absence physical barriers has remained challenging and controversial. The large sizes high rates gene flow characteristic have made resolution geographical differentiation very difficult, especially when using few markers assuming equilibrium conditions. Next-generation sequencing now allows simultaneous sampling hundreds to thousands markers; new analytical approaches allow studies under...
The diversity and specific composition of zooplankton communities have a direct effect on the ecosystem services (e.g. carbon export) structure ocean food webs. In areas where is high, detailed characterization whole community can represent hurdle that prevents complete understanding those processes interactions. One such region Sargasso Sea, among highest in world oceans. As consequence, at Bermuda Atlantic Time-series Study location, most research has focused biomass or particular groups....
Mesophotic Coral Ecosystems (MCEs) occur in the middle to lower photic zone (~30 150 m) of tropical and subtropical regions, are often extensions shallow reef communities, generally hold great importance for local commercial fisheries. Compared their shallower counterpart, MCEs have been traditionally understudied, primarily due inaccessibility with traditional monitoring methodologies. In this study, we aim provide an interdisciplinary assessment biodiversity Bermudan fish communities from...
Abstract Radiolarians are marine protists with a global distribution. Epipelagic radiolarians host photosynthetic endosymbionts, but the identity and specificity of this relationship appears to vary between radiolarian subgroups. While class Acantharea order Collodaria both possess stable relatively specific relationships haptophyte Phaeocystis dinoflagellate Brandtodinium nutricula, respectively, orders Nassellaria Spumellaria (which comprise solitary Polycystinea) might have greater...
Abstract In the epipelagic ocean, genus Oithona is considered as one of most abundant and widespread copepods plays an important role in trophic food web. Despite its ecological importance, little known about cyclopoid genomics. Therefore, we sequenced, assembled annotated genome nana . The comparative genomic analysis integrating available copepod genomes highlighted expansions genes related to stress response, cell differentiation development, including coding Lin12‐Notch‐repeat ( LNR )...
Advances in next-generation sequencing technologies and the development of genome-reduced representation protocols have opened way to genome-wide population studies non-model species. However, species with large genomes remain challenging, hampering genomic resources for a number taxa including marine arthropods. Here, we developed method ecologically important copepod Calanus finmarchicus (haploid genome size 6.34 Gbp). We optimized capture enrichment-based protocol based on 2656...
Particulate organic matter (POM) (fecal pellets) from zooplankton has been demonstrated to be an important nutrient source for the pelagic prokaryotic community. Significantly less is known about chemical composition of dissolved (DOM) produced by these eukaryotes and its influence on ecosystem structure. Zooplankton migrators, which daily transport surface-derived compounds depth, may act as vectors limiting nutrients mesopelagic microbial communities. In this role, increase DOM...
Protists represent the majority of eukaryotic diversity in oceans. They have different functions marine food web, playing essential roles biogeochemical cycles. While available data is rich horizontal and temporal coverage, little known on their vertical structuring, particularly below photic zone. The present study applies V4 18S rDNA metabarcoding to samples collected over three years conjunction with BATS time-series assess protist communities epipelagic mesopelagic zones (0-1000 m)....
Abstract Ocean spring phytoplankton blooms are dynamic periods important to global primary production. We document vertical patterns of a diverse suite eukaryotic algae, the prasinophytes, in North Atlantic Subtropical Gyre with monthly sampling over four years at Bermuda Time-series Study site. Water column structure was used delineate seasonal stability more ecologically relevant than seasons defined by calendar dates. During winter mixing, tiny prasinophytes dominated Class II comprise 46...
Species of Oithona (Copepoda, Cyclopoida) are highly abundant, ecologically important, and widely distributed throughout the world oceans. Although there valid detailed descriptions species, routine species identifications remain challenging due to their small size, subtle morphological diagnostic traits, description geographic forms or varieties. This study examined three (O. similis, O. atlantica nana) occurring in Argentine sector South Atlantic Ocean based on DNA sequence variation a 575...
Copepods of the genus Calanus are key zooplankton species in temperate to arctic marine ecosystems. Despite their ecological importance, identification remains challenging. Furthermore, recent report hybrids among highlights need for diagnostic nuclear markers efficiently identify parental and hybrids. Using next-generation sequencing analysis both genome transcriptome from two sibling species, finmarchicus glacialis, we developed a panel 12 insertion/deletion markers. All showed...
The genus Pseudocalanus (Copepoda, Calanoida) is among the most numerically dominant copepods in eastern North Pacific and Pacific-Arctic waters. We compared population connectivity phylogeography based on DNA sequence variation for a portion of mitochondrial cytochrome oxidase I gene four species with differing biogeographical ranges within these ocean regions. Genetic analyses were linked to characterization biological physical environmental variables each sampled region. Haplotype...
