Enhancing kelp productivity in restoration and assisted adaptation interventions under ocean warming Open
Proactive climate interventions, such as restoration and assisted adaptation, are increasingly being used to secure the persistence of populations under climate change. Such strategies are being proposed globally for declining kelp forests…
Temperature and nutrient source drive population-specific patterns of dissolved inorganic nitrogen uptake in a common kelp Open
Ocean warming and marine heatwaves are among the greatest threats to kelp forests globally, with warm temperatures affecting kelp performance and survival. Resolving the thermal response in nutrient uptake by kelp is an important step towa…

Strong genetic differentiation and low genetic diversity in a habitat‐forming fucoid seaweed (<i>Cystophora racemosa</i>) across 850 km of its range Open
Temperate seaweed forests are among the most productive and widespread habitats in coastal waters. However, they are under threat from climate change and other anthropogenic stressors. To effectively conserve and manage these ecosystems un…

More but Smaller: Marine Heatwaves Exacerbate Size Truncation in Overfished Fish Communities in the Skagerrak Open
As we are progressing through the Anthropocene, it is imperative to understand how ecosystems degraded by historical impacts respond to future pressures. Particular attention should be directed at changes in the distribution and function o…

Strong Environmental and Genome‐Wide Population Differentiation Underpins Adaptation and High Genomic Vulnerability in the Dominant Australian Kelp (<i>Ecklonia radiata</i>) Open
Ongoing and predicted range loss of kelp forests in response to climatic stressors is pressing marine managers to look into the adaptive capacity of populations to inform conservation strategies. Characterising how adaptive genetic diversi…

Arctic and Subarctic marine heatwaves and their ecological impacts Open
The Arctic and Subarctic seas are predicted to become hotspots for marine heatwaves (MHWs). High-latitude marine ecosystems face unique consequences from accelerated warming and sea ice loss, challenging species adapted to cold conditions.…

Impacts of Climate Change on Marine Foundation Species Open
Marine foundation species are the biotic basis for many of the world's coastal ecosystems, providing structural habitat, food, and protection for myriad plants and animals as well as many ecosystem services. However, climate change poses a…

Long‐Term Stability of Marine Forests Facing Moderate Gradual Warming in a Remote Biodiversity Hotspot Open
Aim Ocean warming and marine heatwaves are rapidly reconfiguring the composition of seaweed forests—the world's largest coastal vegetated biome. Seaweed forest responses to climate change in remote locations, which constitute the majority …

Successful conservation and management of kelp forests requires more ambitious use of international law Open
Kelp forests are the world's most extensive vegetated marine ecosystems. They provide critical ecological functions as well as valuable ecosystem services for human societies. Yet, kelp forests have been largely overlooked in international…

Spatial structuring of coral traits along a subtropical-temperate transition zone persists despite localised signs of tropicalisation Open
Climate-driven species range expansions are underway with more tropically affiliated species, including Scleractinian corals, becoming increasingly abundant at higher latitudes. However, uncertainty remains on how these range shifts will a…
View article: Impacts of marine heatwaves in coastal ecosystems depend on local environmental conditions
Impacts of marine heatwaves in coastal ecosystems depend on local environmental conditions Open
Marine heatwaves (MHWs), increasing in duration and intensity because of climate change, are now a major threat to marine life and can have lasting effects on the structure and function of ecosystems. However, the responses of marine taxa …
