A new pathogen transmission mechanism in the ocean: the case of sea otter exposure to the land-parasite Toxoplasma gondii. [PDF]

PLoS ONE, 2013
Toxoplasma gondii is a land-derived parasite that infects humans and marine mammals. Infections are a significant cause of mortality for endangered southern sea otters (Enhydra lutris nereis), but the transmission mechanism is poorly understood.

Natural Kelp (Laminaria japonica) Hydrogel with Anisotropic Mechanical Properties, Low Friction and Self-Cleaning for Triboelectric Nanogenerator

Gels
Kelp is a natural hydrogel material, which has been widely used in food industry. However, as a natural material, its properties have not been well explored. In this work, the surface and mechanical properties of kelp were investigated.

Grazing and Recovery of Kelp Gametophytes Under Ocean Warming

Frontiers in Marine Science, 2022
Kelp forests are economically important ecosystems that support a wealth of biodiversity but are declining globally. They are often replaced by biologically depauperate alternate stable states dominated by turfing algae.

Assessing the role of natural kelp forests in modifying seawater chemistry

Scientific Reports
Climate change is causing widespread impacts on seawater pH through ocean acidification (OA). Kelp forests, in some locations can buffer the effects of OA through photosynthesis.

Dietary sugar kelp consumption inhibits adipose tissue inflammation and fibrosis in male mouse model of diet-induced obesity

Journal of Agriculture and Food Research
We previously demonstrated that consumption of U.S.-grown sugar kelp (Saccharina latissima) prohibits inflammation and fibrosis in the liver and white adipose tissue in male diet-induced obesity (DIO) mice.

Effects of Partial Replacment of Dietary Forage Using Kelp Powder (Thallus laminariae) on Ruminal Fermentation and Lactation Performances of Dairy Cows

Animals, 2019
Background: Kelp powder, which was rich in novel oligosaccharides and iodine might be utilized by the rumen microbiome, promoted the ruminal fermentation and finally enhanced the lactation performance of dairy cows.

Effects of wave-powered water pump upwelling on kelp mariculture: a case study for Gulf of Maine

Frontiers in Marine Science
In kelp aquaculture, higher nitrate concentration increases productivity, and water temperatures within a favorable range promote kelp survival. In specific oceanic regions these environmental conditions can be produced by artificial upwelling. This work

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

PLoS 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.

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.

Substantial kelp detritus exported beyond the continental shelf by dense shelf water transport

Scientific Reports
Kelp forests may contribute substantially to ocean carbon sequestration, mainly through transporting kelp carbon away from the coast and into the deep sea.
