Oxygen-dependent metabolism of dissolved organic matter in hypoxic marine environments

Benjamin N. Daniels, Sarah Wolf, Qi Chen, Fabian Wittmers et autres

Low-oxygen marine environments are dynamic hotspots where microbial activity and dissolved organic matter (DOM) cycling are altered, with implications for understanding ecosystem responses to intensifying anthropogenic pressures. The hypoxic barrier hypothesis (HBH) proposed a mechanism by which DOM cycling could be altered …

Regional connectivity and viability selection in a range-expanding marine species

Andy Lee, Benjamin N. Daniels, Cataixa López, Jean M. Davidson et autres

Abstract Identifying spatial and temporal patterns of connectivity among populations is fundamental to marine ecology, evolutionary biology, and fisheries management. Yet, due to large population sizes and low genetic differentiation among populations, empirical quantification of population connectivity across a species’ entire range …

Cohort tracking using size‐frequency population survey data to estimate individual growth

Crow White, David J. Kushner, Rodrigo Beas, Danielle C. Zacherl et autres

Abstract The relationship between a species' growth rate and its size—its growth function—represents essential biological information for supporting sustainable fisheries and wildlife management. Yet, growth functions are known for only a fraction of species. Progress is especially limited in marine invertebrates, including …

Microbial carbon oxidation in seawater below the hypoxic threshold

Sarah Wolf, Clare Jayawickrama, Craig A. Carlson, Curtis Deutsch et autres

Global oxygen minimum zones (OMZs) often reach hypoxia but seldom reach anoxia. Recently it was reported that Michaelis Menten constants (K m ) of oxidative enzymes are orders of magnitude higher than respiratory K m values, and in the Hypoxic Barrier Hypothesis …

Climate-driven range expansion via long-distance larval dispersal

Cataixa López, Benjamin N. Daniels, EB Freel, Alexandra S. Lee et autres

Climate-driven warming and changes in major ocean currents enable poleward larval transport and range expansions of many marine species. Here, we report the population genetic structure of the gastropod Kelletia kelletii, a commercial fisheries species and subtidal predator with top-down food web …

Genetic adaptation despite high gene flow in a range‐expanding population

Andy Lee, Benjamin N. Daniels, William Hemstrom, Cataixa López et autres

Signals of natural selection can be quickly eroded in high gene flow systems, curtailing efforts to understand how and when genetic adaptation occurs in the ocean. This long-standing, unresolved topic in ecology and evolution has renewed importance because changing environmental conditions are …

Microbiome composition and function within the Kellet’s whelk perivitelline fluid

Benjamin N. Daniels, Jenna Nurge, Chanel De Smet, Olivia Sleeper et autres

ABSTRACT Microbiomes have gained significant attention in ecological research, owing to their diverse interactions and essential roles within different organismal ecosystems. Microorganisms, such as bacteria, archaea, and viruses, have profound impact on host health, influencing digestion, metabolism, immune function, tissue development, and …

Anticipating trade-offs and promoting synergies between small-scale fisheries and aquaculture to improve social, economic, and ecological outcomes

Elizabeth J. Mansfield, Fiorenza Micheli, Rod Fujita, Elizabeth A. Fulton et autres

Abstract Blue food systems are crucial for meeting global social and environmental goals. Both small-scale marine fisheries (SSFs) and aquaculture contribute to these goals, with SSFs supporting hundreds of millions of people and aquaculture currently expanding in the marine environment. Here we …

Genomic DNA extraction optimization and validation for genome sequencing using the marine gastropod Kellet’s whelk

Benjamin N. Daniels, Jenna Nurge, Olivia Sleeper, Andy Lee et autres

Next-generation sequencing technologies, such as Nanopore MinION, Illumina Hiseq and Novaseq, and PacBio Sequel II, hold immense potential for advancing genomic research on non-model organisms, including the vast majority of marine species. However, application of these technologies to marine invertebrate species is …

De novo genome and transcriptome assembly of Kelletia kelletii, a coastal gastropod and fisheries species exhibiting a northern range expansion

Benjamin N. Daniels, Cassidy Andrasz, N. Zarate, Andy Lee et autres

Understanding the genomic characteristics of non-model organisms can bridge research gaps between ecology and evolution. However, the lack of a reference genome and transcriptome for these species makes their study challenging. Here, we complete the first full genome and transcriptome sequence assembly …
