Variability of Seawater Chemistry in a Kelp Forest Environment Is Linked to in situ Transgenerational Effects in the Purple Sea Urchin, Strongylocentrotus purpuratus

open access: yesFrontiers in Marine Science, 2019
While the value of giant kelp (Macrocystis pyrifera) as a habitat-forming foundation species is well-understood, it is unclear how they impact the oxygen concentration and pH of the surrounding seawater, and further, how such a dynamic abiotic ...

Artificial intelligence convolutional neural networks map giant kelp forests from satellite imagery

open access: yesScientific Reports, 2022
Climate change is producing shifts in the distribution and abundance of marine species. Such is the case of kelp forests, important marine ecosystem-structuring species whose distributional range limits have been shifting worldwide.

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

open access: yesPLoS 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.

Restoring and valuing global kelp forest ecosystems [PDF]

open access: yes, 2023
Kelp forests cover ~30% of the world’s coastline and are the largest biogenic marine habitat on earth. Across their distribution, kelp forests are essential for the healthy functioning of marine ecosystems and consequently underpin many of the benefits ...

Floating Kelp Rafts as Indicators of Aggregation Zones within the San Juan Archipelago

open access: yes, 2023
Bull kelp forests line Salish Sea coastlines, providing important ecosystem services to shallow subtidal habitats. Each winter, bull kelp forests are dislodged by winter storms, setting “kelp rafts” adrift on currents.

The Ecology of Microbial Communities Associated with Macrocystis pyrifera. [PDF]

open access: yesPLoS ONE, 2013
Kelp forests are characterized by high biodiversity and productivity, and the cycling of kelp-produced carbon is a vital process in this ecosystem.

The potential role of kelp forests on iodine speciation in coastal seawater.

open access: yesPLoS ONE, 2017
Kelps have a major role in marine and atmospheric iodine cycling in the coastal zone of temperate regions, with potential wide-ranging impacts on ozone destruction in the coastal marine boundary layer.

Impact of the extinct megaherbivore Steller's sea cow (Hydrodamalis gigas) on kelp forest resilience

open access: yesFrontiers in Ecology and Evolution, 2022
Giant kelp forests off the west coast of North America are maintained primarily by sea otter (Enhydra lutris) and sunflower sea star (Pycnopodia helianthoides) predation of sea urchins.

Recruitment as a possible indicator of declining resilience in degraded kelp forests

open access: yesEcological Indicators
Kelp forests are critical marine ecosystems that provide habitat and ecological services, as well as economic benefits. However, kelp forests worldwide are facing multiple pressures, including climate change and human activities.

Functional Insights into the Kelp Microbiome from Metagenome-Assembled Genomes

open access: yesmSystems, 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 ...
