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 ...

Microbiome shifts with onset and progression of Sea Star Wasting Disease revealed through time course sampling. [PDF]
AbstractThe recent outbreak of Sea Star Wasting Disease (SSWD) is one of the largest marine epizootics in history, but the host-associated microbial community changes specific to disease progression have not been characterized. Here, we sampled the microbiomes of ochre sea stars, Pisaster ochraceus, through time as animals stayed healthy or became sick

Common sea stars (Asterias rubens) are at risk of physiological stress and decline with projected shifts in oceanic conditions. This study assessed changes in coelomic fluid (CF) blood gases, electrolytes, osmolality, and coelomocyte counts in adult ...

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

Dam removal is used increasingly to restore aquatic ecosystems and remove unnecessary or high-risk infrastructure. As the number of removals increases, there is a growing understanding about the hydrologic, geomorphic, and ecological responses to these ...

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

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,

Sea Star Wasting Disease in Pisaster Ochraceus on the Washington Coast and in Puget Sound [PDF]
Pisaster ochraceus is a common west coast sea star whose predation of Mytilus californianus (the California mussel) increases the biodiversity of its intertidal community.

Asteroids (Echinodermata) experience mass mortality events that have the potential to cause dramatic shifts in ecosystem structure. Asteroid wasting describes a suite of body wall abnormalities that can ultimately result in animal mortality.
