Winter oceanographic conditions predict summer bull kelp canopy cover in northern California. [PDF]

PLoS ONE, 2022
Bull kelp, Nereocystis luetkeana, is an iconic kelp forest species of the Northeast Pacific that provides a wide range of ecosystem services to coastal marine species and society.

The role of kelp crabs as consumers in bull kelp forests—evidence from laboratory feeding trials and field enclosures [PDF]

PeerJ, 2017
The Northern kelp crab (Pugettia producta) and the graceful kelp crab (Pugettia gracilis) are common primary consumers in bull kelp beds near the San Juan Islands (Salish Sea, NE Pacific).

Cellular basis for blade splitting in bull kelp, Nereocystis luetkeana. [PDF]

Am J Bot
Abstract Premise Blade splitting in bull kelp, Nereocystis luetkeana is central to thallus development and function, yet the cellular basis of this process remains poorly understood. Two historical models proposed contrasting mechanisms: One attributes blade separation primarily to programmed cell death, whereas the other suggests mechanical tearing ...

Lines of dehiscence as a biomechanical strategy for controlling damage during blade development in the bull kelp Nereocystis luetkeana. [PDF]

J Phycol
Abstract Although tearing is most often considered mechanical damage, it plays a central role in blade development in the bull kelp Nereocystis luetkeana. Although developmental tearing has been described in other macrophytes, the presence of a line of dehiscence that directs fracture apart from reproduction or abscission remains rare and poorly ...

Bimodal spore release heights in the water column enhance local retention and population connectivity of bull kelp, Nereocystis luetkeana [PDF]

Ecology and Evolution
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.

Kelpwatch: A new visualization and analysis tool to explore kelp canopy dynamics reveals variable response to and recovery from marine heatwaves [PDF]

PLoS ONE, 2023
Giant kelp and bull kelp forests are increasingly at risk from marine heatwave events, herbivore outbreaks, and the loss or alterations in the behavior of key herbivore predators.

Foundational kelp species reveal links between host traits, the environment and the associated microbial community [PDF]

Royal Society Open Science
Canopy kelp are foundational species in coastal ecosystems and host diverse bacterial communities. Here, we test the association between bull kelp (Nereocystis luetkeana) host traits, blade-associated bacterial taxa and seawater environmental features ...

Incorporating Population Genomic Perspectives Into Kelp Conservation and Aquaculture in the Pacific Northwest. [PDF]

Evol Appl
ABSTRACT Recent kelp forest declines and growth in the kelp aquaculture industry have fueled increasing interest in ecological and evolutionary research on kelp forests, including kelp population genomics. Although many kelp management activities have inherent genetic and evolutionary implications, kelp management in the Pacific Northwest (PNW) of ...

Historical data reveal extirpation of foundation species and kelp forest community deborealization in a coastal hotspot. [PDF]

Ecol Appl
Abstract Climate change is restructuring ecological communities globally, yet the impacts are often underestimated or poorly resolved due to the lack of historical baselines. In temperate oceans, biologically diverse and socioeconomically important kelp forests are the marine ecosystem most threatened by climate change.

Spatial and temporal persistence of nearshore kelp beds on the west coast of British Columbia, Canada using satellite remote sensing

Remote Sensing in Ecology and Conservation, 2020
Bull kelp Nereocystis luetkeana is an important foundation species, providing structural habitat and nutrients to the nearshore ecosystems of temperate coastal regions in the Northeast Pacific.
