Human-caused global change produces biotic and abiotic conditions that increase the uncertainty and risk of failure of restoration efforts. A focus of managing for resiliency, that is, the ability of the system to respond to disturbance, has the potential to reduce this uncertainty and risk. However, identifying what drives resiliency might depend on how one measures it.

Dispersal of reproductive propagules determines recruitment patterns and connectivity among populations and can influence how populations respond to major disturbance events. Dispersal distributions can depend on propagule release strategies. For instance, the bull kelp, , can release propagules (spores) from two heights in the water column ("bimodal release"): at the water surface, directly from the reproductive tissues (sori) on the kelp's blades, and near the seafloor after the sori abscise and sink through the water column.

The recent collapse of predatory sunflower sea stars () owing to sea star wasting disease (SSWD) is hypothesized to have contributed to proliferation of sea urchin barrens and losses of kelp forests on the North American west coast. We used experiments and a model to test whether restored populations may help recover kelp forests through their consumption of nutritionally poor purple sea urchins () typical of barrens. consumed 0.

Nitrate is a major nutrient and osmoticum for plants. To deal with fluctuating nitrate availability in soils, plants store this nutrient in their vacuoles. Chloride channel a (CLCa), a 2NO3-/1H+ exchanger localized to the vacuole in Arabidopsis (Arabidopsis thaliana), ensures this storage process.

Article Synopsis
  • A significant sea star wasting disease has led to massive die-offs along the west coast of North America, affecting billions of sea stars and disrupting coastal ecosystems.
  • The disease manifests as skin lesions and tissue disintegration, but the underlying causes, whether infectious or related to environmental factors, are still not fully understood.
  • The article reviews current knowledge about sea star biology, discusses hypotheses about the disease's symptoms and contributing factors, and emphasizes the need for more research to fill existing gaps and improve management strategies.
