Factors influencing recruitment and appearance of bull kelp, Nereocystis luetkeana (phylum Ochrophyta) [PDF]

, 2018
The dynamics of annual species are strongly tied to their capacity for recruitment each year. We examined how competition and propagule availability influence recruitment and appearance and tracked survivorship of an annual species of marine macroalgae ...

Canopy-forming kelp forests persist in the dynamic subregion of the Broughton Archipelago, British Columbia, Canada

Frontiers in Marine Science
Canopy-forming kelp forests act as foundation species that provide a wide range of ecosystem services along temperate coastlines. With climate change, these ecosystems are experiencing changing environmental and biotic conditions; however, the kelp ...

Trophic Transfer of Macroalgal Fatty Acids in Two Urchin Species: Digestion, Egestion, and Tissue Building

Frontiers in Ecology and Evolution, 2018
Sea urchins are ecosystem engineers of nearshore benthic communities because of their influence on the abundance and distribution of macroalgal species.

Centennial persistence of kelp forests on the West Coast of Vancouver Island, Canada

Frontiers in Marine Science
Canopy-forming kelps, bull kelp (Nereocystis luetkeana) and giant kelp (Macrocystis tenuifolia), form dynamic underwater forests that underpin coastal biodiversity, fisheries, and human well-being.

Models reveal potential synergies in management actions for bull kelp forest resilience and restoration

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
We found that urchin culling and kelp seeding interventions can be effective at rebuilding kelp forests, but require intensive effort (e.g. removing 25%–50% of urchins over multiple years), especially in the absence of predators. Our results provide recommendations for the magnitude and timing of culling and seeding that would be needed to provide ...

DataSheet_1_Interactive effects of temperature and nitrogen on the physiology of kelps (Nereocystis luetkeana and Saccharina latissima).zip

, 2023
Kelp forest declines have been linked to warming ocean temperatures worldwide. Ocean warming rarely occurs in isolation, so multiple stressor studies are necessary to understand the physiological responses of kelp to climate change.

Severity and certainty metric for kelp stressors: A tool for research, management, and conservation

Ecological Indicators
Foundation species face multiple threats, and many are in decline worldwide. Kelps are no exception, with declines documented throughout their range. Stressors such as warming, eutrophication, and reduced water quality—often linked to human activities ...

Capturing accurate kelp canopy extent: integrating tides, currents, and species-level morphology in kelp remote sensing

Frontiers in Environmental Science
Surface-canopy forming kelps (Macrocystis pyrifera and Nereocystis luetkeana) can be monitored along the Northeast Pacific coast using remote sensing. These kelp canopies can be submerged by tides and currents, making it difficult to accurately determine

Biomarkers of recovery: Characterizing trophic flow following ecological restoration

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Fatty acid biomarkers offer a scalable tool for detecting early trophic recovery, identifying high‐leverage depth strata for intervention, and evaluating whether restoration actions are rebuilding the ecosystem functions and fisheries‐relevant nutritional pathways that support resilient kelp forest ecosystems.

Back to the past: long-term persistence of bull kelp forests in the Strait of Georgia, Salish Sea, Canada

Frontiers in Marine Science
The Salish Sea, a dynamic system of straits, fjords, and channels in southwestern British Columbia, is home to ecologically and culturally important bull kelp (Nereocystis luetkeana) forests. Yet the long-term fluctuations in the area and the persistence
