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 ...

Effects of competition and dispersal on the recruitment of the annual kelp Nereocystis luetkeana [PDF]

, 2010
In central California, the role of algal assemblages on the recruitment of the canopy producing annual kelp Nereocystis luetkeana was examined by experimentally manipulating canopy and understory algae within 1) a Macrocysits bed and 2) a Nereocystis bed.

Standardized 16S Meta-Analysis Reveals Consistent Host-Associated Patterns in Laminariales Epiphytic Microbiomes. [PDF]

Microbiologyopen
An integrated bioinformatic pipeline combining taxonomic, functional, and network analyses revealed host‐driven structuring of macroalgal microbiomes. Phaeophyceae hosted distinct epiphytic communities enriched in chemoheterotrophy and polysaccharide degradation, highlighting metabolic coupling, keystone taxa, and a standardized framework for ...

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 inference of ancestor locations suggests northern refugia for canopy-forming kelps in the Pacific Northwest. [PDF]

New Phytol
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

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 ...

Effects of Competition and Dispersal on the Recruitment of the Annual Kelp Nereocystis luetkeana [PDF]

, 2019
In central California, the role of algal assemblages on the recruitment of the canopy producing annual kelp Nereocystis luetkeana was examined by experimentally manipulating canopy and understory algae within 1) a Macrocysits bed and 2) a Nereocystis bed.

Long-term changes in kelp forests in an inner basin of the Salish Sea.

PLoS ONE, 2021
Kelp forests form an important biogenic habitat that responds to natural and human drivers. Global concerns exist about threats to kelp forests, yet long-term information is limited and research suggests that trends are geographically distinct.

An investigation into the efficacy of Biokos® in controlling ciliates in laboratory cultures of Saccharina latissima gametophytes. [PDF]

J Phycol
Abstract A major challenge faced by kelp aquaculture operations is the control of contaminants, including by marine ciliates. Biokos® is a commercially available treatment for ciliate parasites in fish, in which the active ingredient is a viscosin‐like lipopeptide surfactant.
