Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics. [PDF]
J PhycolAbstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Minimising Risks of Reduced Genetic Diversity in Marine Restoration. [PDF]
Evol ApplABSTRACT Marine habitat restoration is expanding globally and increasingly relies on aquaculture and hatchery‐based propagation, yet the genetic consequences of producing and outplanting large numbers of habitat‐forming organisms remain poorly evaluated.

Carbon Monoxide a Respiration Product of Nereocystis Luetkeana [PDF]
Botanical Gazette, 1920 1. The existence of a percentage of carbon monoxide in the gas contained in the pneumatocyst of the Pacific Coast kelp Nereocystis Luetkeana is confirmed. 2. The substance of the kelp when ground and allowed to undergo autolysis and decay does not form carbon monoxide by enzyme action or fermentation process. 3.

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).

Functional Insights into the Kelp Microbiome from Metagenome-Assembled Genomes
mSystems, 2022 Eukaryotic organisms evolved in a microbial world and often have intimate associations with diverse bacterial groups. Kelp, brown macroalgae in the order Laminariales, play a vital role in coastal ecosystems, yet we know little about the functional role ...

Consumer resilience suppresses the recovery of overgrazed ecosystems. [PDF]
Ecol ApplAbstract Many heterotroph species perish when faced with severe food limitation; others can persist, adapt, and thrive. Sea urchins are emblematic of this paradox: they can overgraze kelp forests to form barren habitats, but can then survive for decades in these nutritionally depauperate seascapes.

Frontiers in Marine Science, 2023 IntroductionIn temperate regions, one of the most critical determinants of present range-wide genetic diversity was the Pleistocene climate oscillations, the most recent one created by the last glacial maximum (LGM).

Journal of Phycology, 2023 AbstractWarming ocean temperatures have been linked to kelp forest declines worldwide, and elevated temperatures can act synergistically with other local stressors to exacerbate kelp loss. The bull kelp Nereocystis luetkeana is the primary canopy‐forming kelp species in the Salish Sea, where it is declining in areas with elevated summer water ...

Chromosomal alternation of generations in Nereocystis luetkeana (mertens) Postels and Ruprecht [PDF]
Canadian Journal of Botany, 2012 A cytological examination of the life-history of Nereocystis luetkeana has shown that an alternating chromosome number corresponds to the morphological alternation of generations. The first division sequence of the zoosporangial nucleus is meiotic and is followed by three mitotic divisions. The result is a mature sporangium containing 32 nuclei. Thirty-

Remote Sensing, 2022 Kelp forests are commonly classified within remote sensing imagery by contrasting the high reflectance in the near-infrared spectral region of kelp canopy floating at the surface with the low reflectance in the same spectral region of water.
