Regulatory Approaches in the Face of a Pandemic: Assessing the Role of Ideology, Context, and Rule Design in Four Spanish Regions

open access: yesPublic Administration, EarlyView.
ABSTRACT Regulatory instruments to manage the COVID‐19 pandemic have been the object of rich scholarly debates, primarily focused on early national responses to the crisis. We investigate variation in sub‐national regulatory approaches when a crisis is normalized, its association with competing political ideas about the health‐economy trade‐off and the

Spatiotemporal Forecasting of Mediterranean Blue Mussel Biofouling Settlement to Inform Aquaculture Management

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Mediterranean blue mussel (Mytilus galloprovincialis) settlement significantly influences aquaculture productivity and biofouling management in New Zealand's coastal waters due to its rapid colonization of farming infrastructure and its competitive interactions with cultivated species.

Gamma-ray Burst Remnants: How can we find them?

open access: yes, 2001
By now there is substantial evidence that Gamma-Ray Bursts (GRBs) originate at cosmological distances from very powerful explosions. The interaction between a GRB and its surrounding environment has dramatic consequences on the environment itself.

The Migratory Behaviour of Juvenile GreenshellTM Mussels (Perna canaliculus)

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Migratory behaviour is a major cause of juvenile mussel (spat) losses, with estimates of 50%–100% in many parts of the world, significantly impacting production efficiency. Reducing spat losses due to their migratory behaviour is essential for improving yields and sustainability, as it can help decrease substantial economic losses, such as the

Refining Spat‐Collection Practices to Optimise Single‐Seed Spat Production for New Zealand's Greenshell (Perna canaliculus) Mussel Industry

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Mussel aquaculture depends on a consistent spat supply, often sourced from spat‐collection ropes suspended in coastal waters. However, settlement on these ropes can be highly variable due to environmental factors. Therefore, improving spat supply from this source relies on optimising aspects of the process, particularly the timing of ...

Methods for Improving Settlement and Metamorphosis of Shelled Marine Mollusks in Aquaculture: A Review

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations
