A Comparison of Juvenile and Adult Sunflower Sea Star Transcriptomic Responses to Challenge With Sea Star Wasting Disease Tissue Homogenates [PDF]
Sea star wasting disease (SSWD) has impacted over twenty sea star species along the Northeast Pacific Coast, with some seemingly more susceptible than others.

Sea stars are ecologically important in rocky intertidal habitats where they can play an apex predator role, completely restructuring communities. The recent sea star die-off throughout the eastern Pacific, known as Sea Star Wasting Disease, has prompted

What doesn’t kill them makes them stronger: An association between elongation factor 1-α overdominance in the sea star Pisaster ochraceus and "sea star wasting disease” [PDF]
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

Lessons Learned from the Sea Star Wasting Disease Investigation
Marine invertebrate mass mortality events (MMEs) threaten biodiversity and have the potential to catastrophically alter ecosystem structure. A proximal question around acute MMEs is their etiologies and/or environmental drivers.

Resistance of rocky intertidal communities to oceanic climate fluctuations. [PDF]
A powerful way to predict how ecological communities will respond to future climate change is to test how they have responded to the climate of the past.

Star Power: Early life stages of an endangered sea star are robust to current and near-future warming. [PDF]
The sunflower star, Pycnopodia helianthoides, was a top benthic predator throughout its former range from Alaska to northern Mexico, until its populations were devastated starting in 2013 by a disease known as seastar wasting.

AbstractSea stars are keystone species and their mass die-offs due to sea star wasting disease (SSWD) impact marine communities and have fueled recent interest in the microbiome of sea stars. We assessed the host specificity of the microbiome associated with three body regions of the sea star Pisaster ochraceus using 16S rRNA gene amplicon surveys of ...

Sea Star Wasting Disease (SSWD) affects several wild and captive starfish species. It is generally thought to be infectious, with environmental conditions favouring its progression. Captive Asterias rubens with varying degrees of epidermal ulceration, limb autotomy and eversion of viscera were examined. Antibiotic treatments by injections and baths did

Can crabs kill like a keystone predator? A field-test of the effects of crab predation on mussel mortality on a northeast Pacific rocky shore. [PDF]
Predation can strongly influence community structure and ecosystem function, so the loss of key predators can have dramatic ecological consequences, unless other predatory species in the system are capable of playing similar ecological roles. In light of

Evidence for a trophic cascade on rocky reefs following sea star mass mortality in British Columbia [PDF]
Echinoderm population collapses, driven by disease outbreaks and climatic events, may be important drivers of population dynamics, ecological shifts and biodiversity. The northeast Pacific recently experienced a mass mortality of sea stars. In Howe Sound,
