Interactive effects of temperature and nitrogen on the physiology of kelps (Nereocystis luetkeana and Saccharina latissima) [PDF]

Frontiers in Marine Science, 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.

Passive remote sensing technology for mapping bull kelp (Nereocystis luetkeana): A review of techniques and regional case study

Global Ecology and Conservation, 2019
The distribution and abundance of the canopy-forming kelp Nereocystis luetkeana is of increasing concern for environmental management and conservation in coastal regions due to its importance as a foundation species.

Chemical contaminant levels in edible seaweeds of the Salish Sea and implications for their consumption. [PDF]

PLoS ONE, 2022
Despite growing interest in edible seaweeds, there is limited information on seaweed chemical contaminant levels in the Salish Sea. Without this knowledge, health-based consumption advisories can not be determined for consumers that include Tribes and ...

The Diversity and Functional Capacity of Microbes Associated with Coastal Macrophytes [PDF]

mSystems, 2022
Coastal marine macrophytes exhibit some of the highest rates of primary productivity in the world. They have been found to host a diverse set of microbes, many of which may impact the biology of their hosts through metabolisms that are unique to ...

The reference genome for the northeastern Pacific bull kelp, Nereocystis luetkeana

Journal of Heredity
Abstract Bull kelp, Nereocystis luetkeana, is a northeastern Pacific kelp with a broad distribution from Alaska to central California. Its population declines have caused severe concerns in northern California, the Salish Sea in Washington, and recently in some populations in Oregon.

Unusual morphologies raise questions about the evolution of branching in kelps (Laminariales) [PDF]

Ecology and Evolution
Branching stipe morphologies have evolved multiple times across the kelp (Laminariales) lineage, creating morphological forms that drive the complexity of kelp forest habitats.

Ammonification by kelp associated microbes increases ammonium availability. [PDF]

PLoS ONE
Microbes contribute biologically available nitrogen to the ocean by fixing nitrogen gas from the atmosphere and by mineralizing organic nitrogen into bioavailable dissolved inorganic nitrogen (DIN). Although the large concentration of plants and algae in

Spatial organization of the kelp microbiome at micron scales [PDF]

Microbiome, 2022
Background Elucidating the spatial structure of host-associated microbial communities is essential for understanding taxon-taxon interactions within the microbiota and between microbiota and host. Macroalgae are colonized by complex microbial communities,

Evolutionary history and association with seaweeds shape the genomes and metabolisms of marine bacteria [PDF]

mSphere
Seaweeds harbor a rich diversity of bacteria, providing them with metabolic resources and a surface for attachment and biofilm development. The host’s unique environment potentially shapes the bacterial genomes and promotes adaptations for a symbiotic ...

Bull kelp (Nereocystis luetkeana) growth rates as climate stress indicators for Canada’s Pacific coast

Facets
Primary producers’ growth rates are ideal bioindicators of changing climate due to their sensitivity to environmental conditions. On the Central Coast of British Columbia, we assessed growth rates of Nereocystis luetkeana, a canopy-forming annual kelp ...
