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,...
Abstract. The largest and commercially appealing mineral deposits can be found in the abyssal sea floor of Clarion-Clipperton Zone (CCZ), a polymetallic nodule province, NE Pacific Ocean, where experimental mining is due to take place. In anticipation deep-sea impacts, it has become essential rapidly accurately assess biodiversity. For this reason, ophiuroid material collected during eight scientific cruises from five exploration licence areas within CCZ, one area being protected (APEI3,...
Nowadays, most biodiversity assessments involving meiofauna are mainly carried out specimen by based on morphological identifications, which is very time-consuming and demands comprehensive taxonomic knowledge. Specimens have to be examined for minor differences of setae compositions, mouthpart morphology or number segments various extremities. DNA-based methods such as metabarcoding well recently emerged rapid analyses using MALDI-TOF mass spectrometry identify specimens a proteome...
Microbial composition and diversity in marine sediments are shaped by environmental, biological, anthropogenic processes operating at different scales. However, our understanding of benthic microbial biogeography remains limited. Here, we used 16S rDNA amplicon sequencing to characterize microbiota the North Sea from top centimeter 339 sediment samples. We utilized spatially explicit statistical models, disentangle effects predictors, including bottom trawling intensity, a prevalent...
Abstract Brittle stars (Echinodermata: Ophiuroidea) comprise over 2, 000 species, all of which inhabit marine environments and can be abundant in the deep sea. Morphological plasticity number shape skeletal parts, as well variable colors, complicate correct species identification. Consequently, DNA sequence analysis play an important role In this study we compared genetic variability mitochondrial cytochrome c subunit I gene (COI) nuclear small ribosomal (SSU, 18S rDNA) to morphological...
Abstract Polymetallic nodule fields represent a large reservoir of undiscovered biodiversity that becomes particularly evident for meiobenthic organisms, the smallest-sized faunal group. Knowledge gaps are especially noticeable generally low-density metazoan groups, such as Kinorhyncha, so-called mud dragons. Using both morphological and genetic (metabarcoding) approaches, we provide general overview comparison diversity kinorhynchs collected during nine sampling campaigns (2016–2019)...
Mastigodiaptomus is the most common diaptomid in Southern USA, Mexico, Central America and Caribbean freshwaters, nevertheless its distributional patterns diversity cannot be stablished because of presence cryptic species hidden under wide distributed forms. Herein we study morphological molecular variation calanoid fauna from two Biosphere Reserves Yucatan Peninsula describe a new genus Mastigodiaptomus. Our findings are compared with other lineages previously found Mexico. siankaanensis...
Recent years have seen a rapid increase in survey and sampling expeditions to the Clarion-Clipperton Zone (CCZ) abyssal plain, vast area of central Pacific that is currently being actively explored for deep-sea minerals (ISA, 2016). Critical development evidence-based environmental policy CCZ are data on biogeography connectivity species at CCZ-regional level. The London Workshop Biogeography Connectivity was convened support integration synthesis from European Union (EU) projects, supported...
Subterranean estuaries (STEs) play an important role in linking nutrient cycling between marine and terrestrial systems. As being the primary drivers of cycling, composition microbial communities their adaptation toward both, conditions are special interest. While bacterial STEs have received increasing scientific attention, archaeal meiofaunal diversity was mostly neglected. Previous studies at investigated sampling site, STE a mesotidal beach German North Sea island Spiekeroog, focused on...
Abstract Background The family Aegisthidae is known as typical component of deep-sea hyperbenthic waters that gradually colonized other marine environments. phylogenetic relationships within this have been examined here including hyperbenthic, planktonic, benthic forms and two associated species. Results Ninety four specimens belong to 14 genera were studied using 18S 28S rRNA COI mtDNA. Bayesian analysis supports the monophyly 10 whereas Andromastax, Jamstecia , Nudivorax Aegisthus revealed...

A substantial fraction of the freshwater available in Neotropical forests is enclosed within rosettes bromeliads that form small aquatic islands a terrestrial landscape. These oases provide shelter, water, nutrients and resting aggregation sites for several organisms, among them crustaceans. However, comparison with multitude studies on open systems, our knowledge crustaceans inhabiting semi-terrestrial habitats phytotelmata limited their presence such environments poorly understood. The...
Sand nourishment is a common and often applied coastal protection measure along the beaches of German Baltic Sea coast. At tourist beach Ahrenshoop, large-scale sand nourishments are completed every five years 4-km stretch. The in question was executed between end October 2021 mid-February 2022. Meiofaunal communities at beach-water interface were monitored six stations before (September 2021) for one year after impact (March September 2022, March 2023). To assess effects on meiofauna...
Anthropogenic carbon dioxide (CO 2 ) emissions drive climate change and pose one of the major challenges our century. The effects increased CO in form ocean acidification (OA) on communities marine planktonic eukaryotes tropical regions such as Timor Sea are barely understood. Here, we show high (mean ± SD p = 1823 161 μatm pH T 7.46 0.05) versus situ (504 42 µatm, 7.95 0.04) seawater community composition after 3 48 h treatment exposure a shipboard microcosm experiment.

Benthic protist communities, including sand-dwelling dinoflagellates, are still poorly characterized worldwide and there is a lack of knowledge on their diversity spatiotemporal dynamics. In this study, sediments were obtained from several coastal locations the German Wadden Sea during summer months 2017 2018 to determine distribution dinoflagellates. The analyses consisted light microscopy metabarcoding small subunit (SSU) rRNA gene V4 region amplicons. Additionally, SSU sequences newly for...
ABSTRACT Microbial composition and diversity in marine sediments are shaped by environmental, biological, anthropogenic processes that operate on different scales. However, our understanding of benthic microbial biogeography remains limited. Here, we study how microbiota vary at a regional scale the North Sea with sediment characteristics, temperature, organic matter content, shear bed stress bottom trawling intensity, prevalent industrial fishing practice which heavily impacts ecosystems....
