Sea star wasting—marked in a variety of sea star species as varying degrees of skin lesions followed by disintegration— recently caused one of the largest marine die-offs ever recorded on the west coast of North America, killing billions of sea stars. Despite the important ramifications this mortality had for coastal benthic ecosystems, such as inc...
Article
Sea star wasting (SSW) disease describes a condition affecting asteroids that resulted in significant Northeastern Pacific population decline following a mass mortality event in 2013. The etiology of SSW is unresolved. We hypothesized that SSW is a sequela of microbial organic matter remineralization near respiratory surfaces, one consequence of wh...

Sea star wasting (SSW) disease describes a condition affecting asteroids that resulted in significant Northeastern Pacific population decline following a mass mortality event in 2013. The etiology of sea star wasting is unresolved. We hypothesize that asteroid wasting is a sequela of microbial organic matter remineralization near respiratory surfac...
Article
Beginning in 2013, sea stars throughout the Eastern North Pacific were decimated by wasting disease, also known as ‘asteroid idiopathic wasting syndrome’ (AIWS) due to its elusive etiology. The geographic extent and taxonomic scale of AIWS meant events leading up to the outbreak were heterogeneous, multifaceted, and oftentimes unobserved; progressi...
Article
Documenting ecological patterns across spatially, temporally and taxonomically diverse ecological communities is necessary for a general understanding of the processes shaping biodiversity. A major gap in our understanding remains the comparison of diversity patterns across a broad spectrum of evolutionarily and functionally diverse organisms, part...
Article
Aim Theory predicts that differences in phylogeographic structure between species should be related to differences in life history, environment, and evolutionary time. Reviews of empirical studies suggest sometimes complex interactions and possibly a preponderance of exceptions to the predicted relationship that greater population genetic different...
Article
Full-text available
Standing genetic variation enables or restricts a population's capacity to respond to changing conditions, including the extreme disturbances expected to increase in frequency and intensity with continuing anthropogenic climate change. However, we know little about how populations might respond to extreme events with rapid genetic shifts, or how po...
Article
The inclusion of next-generation sequencing technologies in population genetic and phylogenetic studies has elevated the need to balance time and cost of DNA extraction without compromising DNA quality. We tested eight extraction methods — ranging from low- to high-throughput techniques — and eight phyla: Annelida, Arthropoda, Cnidaria, Chordata, E...

In recent years, a massive mortality event has killed millions of sea stars, of many different species, along the Pacific coast of North America. This disease event, known as ‘sea star wasting disease’ (SSWD), is linked to viral infection. In one affected sea star ( Pisaster ochraceus ), previous work had identified that the elongation factor 1- α...
Data
Genotype and metadata for analyzed specimens of Pisaster All individual genotype data are provided in this spreadsheet, with the “Master Data” tab including all genotype and metadata used in analyses. Additional information specific to site collections are located on other tabs in the spreadsheet.
Data
Binomial regression output and AIC model selection information This file provides output from model calls on raw data, sorted by model, followed by AIC model selection information.

In recent years, a massive plague has killed millions of sea stars, of many different species, along the Pacific coast of North America. This disease, known as 'sea star wasting disease' (SSWD), is thought to be caused by viral infection. In the affected sea star Pisaster ochraceus , previous work had identified that the elongation factor 1-α (EF1A...

Full-text available
Mass mortalities in natural populations, particularly those that leave few survivors over large spatial areas, may cause long-term ecological perturbations. Yet mass mortalities may remain undocumented or poorly described due to challenges in responding rapidly to unforeseen events, scarcity of baseline data, and difficulties in quantifying rare or...
