Rapid evolution of a large structural polymorphism during a bacterial epidemic Open
The field of population genetics is primarily focused on simple genetic variants such as single nucleotide polymorphisms (SNPs), small insertions or deletions (INDELs), and copy-number variants (CNVs). However, large-scale genomic variants…

Aphid herbivory on macrophytes drives adaptive evolution in an aquatic community via indirect effects Open
Indirect ecological effects occur when the impact of one species on another is mediated by a third species or the shared environment. Although indirect effects are ubiquitous in nature, we know remarkably little about how they may drive ec…

Terrestrial herbivory drives adaptive evolution in an aquatic community via indirect effects Open
Indirect ecological effects, which occur when the impact of one species on another is mediated by a third species or the shared environment, are ubiquitous in nature. Given the complexity of natural systems, indirect ecological effects wer…

Genome assemblies and annotations of two species of porcelain crabs, <i>Petrolisthes cinctipes</i> and <i>Petrolisthes manimaculis</i> (Anomura: Porcellanidae) Open
The genomes of the two species, Petrolisthes cinctipes and Petrolisthes manimaculis, assembled into 0.9-1.5 Gb, of which 60-74% was repetitive, and had 42-46K protein coding genes. CSV files are used to link the IDs used in the paper to th…

Genome assemblies of two species of porcelain crab, <i>Petrolisthes cinctipes</i> and <i>Petrolisthes manimaculis</i> (Anomura: Porcellanidae) Open
Crabs are a large subtaxon of the Arthropoda, the most diverse and species-rich metazoan group. Several outstanding questions remain regarding crab diversification, including about the genomic capacitors of physiological and morphological …

Uncovering the Genomic Basis of Infection Through Co-genomic Sequencing of Hosts and Parasites Open
Understanding the genomic basis of infectious disease is a fundamental objective in co-evolutionary theory with relevance to healthcare, agriculture, and epidemiology. Models of host-parasite co-evolution often assume that infection requir…

Genetic slippage after sex maintains diversity for parasite resistance in a natural host population Open
Although parasite-mediated selection is a major driver of host evolution, its influence on genetic variation for parasite resistance is not yet well understood. We monitored resistance in a large population of the planktonic crustacean Dap…

Modeling the trophic impacts of invasive zooplankton in a highly invaded river Open
The lower Columbia River (Washington and Oregon, USA) has been heavily invaded by a large number of planktonic organisms including the invasive copepod Pseudodiaptomus forbesi and the planktonic juveniles of the invasive clam, Corbicula fl…

Native and invasive zooplankton show differing responses to decadal‐scale increases in maximum temperatures in a large temperate river Open
It has been widely proposed that increasing global temperatures will promote the geographic spread of invasive species, yet few studies have examined the effects of increasing temperatures on existing populations of invaders. Here, we exam…

Zooplankton invasion on a grand scale: insights from a 20‐yr time series across 38 Northeast Pacific estuaries Open
We present the first comprehensive analysis of the Pacific Northwest estuaries ( PNWE ) zooplankton time series, which encompasses 38 estuaries distributed across more than 1000 km of the North American Pacific Coast. With observations spa…

Biotic vs. abiotic forcing on plankton assemblages varies with season and size class in a large temperate estuary Open
Large river estuaries experience multiple anthropogenic stressors. Understanding plankton community dynamics in these estuaries provides insights into the patterns of natural variability and effects of human activity. We undertook a 2-year…

The trouble with stress: A flexible method for the evaluation of nonmetric multidimensional scaling Open
Nonmetric multidimensional scaling (NMDS) is a powerful statistical tool which enables complex multivariate data sets to be visualized in a reduced number of dimensions. Users typically evaluate the fit of an NMDS ordination via ordination…

Persistent vs. ephemeral invasions: 8.5 years of zooplankton community dynamics in the Columbia River Open
Nonindigenous aquatic species are becoming increasingly common in coastal and inland waters, largely due to the global transport of zooplankton via commercial shipping and recreational boating. The cost of mitigation and lost income due to…
