Comprising over 15 000 living species, decapods (crabs, shrimp and lobsters) are the most instantly recognizable crustaceans, representing a considerable global food source. Although decapod systematics have received much study, limitations of morphological Sanger sequence data yet to produce consensus for higher-level relationships. Here, we introduce new anchored hybrid enrichment kit phylogenetics designed from genomic transcriptomic sequences that used capture high-throughput 94...
Since the late 1800s, several infraordinal relationships have been proposed for Decapoda; however, reaching a consensus among higher-level is proving difficult. Molecular methods were first applied to decapod phylogenetics in 1990s and significantly contributed our understanding of group: sampling becoming more thorough, greater number phylogenetically informative characters are being sequenced, analysis procedures consistent between studies. However, deep lineages Decapoda remain unclear....
Sipuncula is a relatively small taxon with roughly 150 recognized species. Many species are geographically widespread or "cosmopolitan." The pelagosphera larvae of some estimated to spend several months in the plankton. However, recent molecular evidence suggests that many "cosmopolitan" actually represent species-complexes, not even monophyletic. Herein, we present data on three sipunculan different developmental modes occur both Sea Japan and Northeast Pacific. development...
Abstract Sablefish (Anoplopoma fimbria) are a highly mobile species that support important commercial fisheries in the North Pacific Ocean. Information on genetic stock structure of sablefish is vital for constructing management strategies ensure long-term viability species. Most previous studies have found panmixia throughout majority their range, but recent study suggested population may exist. Here, we use low-coverage whole genome resequencing to investigate northern end species’ range...
The Amazon-Orinoco plume (AOP) is the world's largest freshwater and sediment discharge into ocean. Previous studies limited to mtDNA suggest that swimming crab
The Gulf of Mexico experiences frequent perturbations, both natural and anthropogenic. To better understand the impacts these events, we must inventory variability within ecosystem, communities, species, populations, contextualize findings in relation to physical features. Here, present an integrated study comparative population genomics biophysical oceanography. Targeting three species mesopelagic shrimp common midwater (Acanthephyra purpurea, Systellaspis debilis, Robustosergia robusta),...
Abstract The application of DNA barcoding represents a complementary and efficient approach to identifying specimens at all stages their life cycle when used in combination with traditional morphological methods. Due difficulties obtaining samples from the deep sea (> 200 m), these methods have been less frequently applied deep-water taxa. We DNA-barcoding techniques enhance large-scale biodiversity initiatives for deep-pelagic crustaceans within Gulf Mexico, region that has recently...
Species of Farfantepenaeus support economically important shrimp fisheries throughout the Western Hemisphere, necessitating proper management. To be effective, species management should informed potential presence cryptic and evolutionary forces driving biodiversity. This is best accomplished through a robust phylogenetic framework evidence-based delimitation. study represents first comprehensive molecular phylogeny delimitation analyses shrimps belonging to genus Farfantepenaeus. Targeting...
Abstract Schistosomiasis persists in Asian regions despite aggressive elimination measures. To identify factors enabling continued parasite transmission, we performed reduced representation genome sequencing on Schistosoma japonicum miracidia collected across multiple years from transmission hotspots Sichuan, China. We discovered strong geographic structure, suggesting that local, rather than imported, reservoirs are key sources of persistent infections the region. At village level,...
Genomic approaches hold great promise for resolving unanswered questions about transmission patterns and responses to control efforts schistosomiasis other neglected tropical diseases. However, the cost of generating genomic data challenges associated with obtaining sufficient DNA from individual schistosome larvae (miracidia) mammalian hosts have limited application studying schistosomes complex macroparasites. Here, we demonstrate feasibility utilizing whole genome amplification sequencing...

Abstract The deep waters of the open ocean represent a major frontier in exploration and scientific understanding. However, modern technological computational tools are making more accessible than ever before by facilitating increasingly sophisticated studies ecosystems. Here, we describe some cutting-edge technologies that have been employed Deep Pelagic Nekton Dynamics Gulf Mexico (DEEPEND; <ext-link ext-link-type="uri"...
Knowledge about early immunity to SARS-CoV-2 variants of concern mainly comes from the analysis human blood. Such data provide limited information host responses at site infection and largely miss initial events. To gain insights into compartmentalization dynamics different variants, we utilized angiotensin converting enzyme 2 (hACE2) transgenic mice tracked immune changes during first days after by RNAseq, multiplex assays, flow cytometry. Viral challenge led divergent viral loads in lungs,...
Abstract Inferences made from molecular data support regional stock assessment goals by providing insights into the genetic population dynamics of enigmatic species. Population genomics metrics, such as diversity and connectivity, serve useful proxies for species health stability. Sleeper sharks (genus Somniosus) are ecologically important deep-sea predators, estimated to reach ages 250 300 yr taking decades sexual maturity. The subgenus Somniosus (Somniosus) is comprised 3 species: S....
ABSTRACT High‐latitude ocean basins are the most productive on earth, supporting high diversity and biomass of economically socially important species. A long tradition responsible fisheries management has sustained these species for generations, but modern threats from climate change, habitat loss, new fishing technologies threaten their ecosystems human communities that depend them. Among species, Alaska's charismatic megafaunal invertebrate, red king crab, faces all three declined...
Abstract Schistosomiasis persists in some Asian regions despite targeted end-game elimination measures. To determine the causes of this persistence, we performed reduced representation genome sequencing on Schistosoma japonicum miracidia collected across multiple years from transmission hotspots Sichuan, China. We discovered strong geographic structure, suggesting that local rather than imported reservoirs are key sources infection persistence. At village level, parasites after praziquantel...
The Gulf of Mexico pink shrimp, Farfantepenaeus duorarum , supports large fisheries in the United States and Mexico, with nearly 7,000 tons harvested from region 2016. Given commercial importance this species, management is critical: 1997, southern shrimp fishery was declared collapsed mitigation strategies went into effect, recovery efforts lasting over a decade. Fisheries can be informed improved through better understanding how factors associated early life history impact genetic...
Seascape genomics provides a powerful framework to evaluate the presence and strength of environmental pressures on marine organisms, as well forecast long term species stability under various perturbations. In highly productive North Pacific, forage fishes, key trophic links across ecosystems, are also contending with rapidly warming climate litany associated oceanographic changes (e.g., in salinity, dissolved oxygen, pH, primary production, etc.). These can place substantial selective...
