Establishing fluvial silicon regimes and their stability across the Northern Hemisphere Open
Fluvial silicon (Si) plays a critical role in controlling primary production, water quality, and carbon sequestration through supporting freshwater and marine diatom communities. Geological, biogeochemical, and hydrological processes, as w…

Stress alters the role of silicon in controlling plant water movement Open
One function of plant Si is ameliorating stress, including drought and salinity stress, which can induce active Si uptake in addition to passive uptake via transpiration. However, the interactions and feedbacks between stress, water moveme…

Long‐Term Changes in Concentration and Yield of Riverine Dissolved Silicon From the Poles to the Tropics Open
Riverine exports of silicon (Si) influence global carbon cycling through the growth of marine diatoms, which account for ∼25% of global primary production. Climate change will likely alter river Si exports in biome‐specific ways due to int…

Resource availability and plant age drive defense against herbivory in salt marshes Open
The resource‐availability hypothesis (RAH) and the intraspecific RAH (RAH intra ), posit that resources, (i.e. nutrients) control plant antiherbivore defenses. Both hypotheses predict that in low‐resource environments, plant growth is slow…

We Must Stop Fossil Fuel Emissions to Protect Permafrost Ecosystems Open
Climate change is an existential threat to the vast global permafrost domain. The diverse human cultures, ecological communities, and biogeochemical cycles of this tenth of the planet depend on the persistence of frozen conditions. The com…

High Productivity Makes Mangroves Potentially Important Players in the Tropical Silicon Cycle Open
Over the last two decades, recognition of the important role terrestrial plants play in regulating silicon (Si) cycling has emerged. Si improves plant fitness by protecting them from abiotic (e.g., desiccation) and biotic (e.g., fungal att…

Mangrove %Si data Open
This dataset contains biogenic silica concentrations of mangrove foliage, twigs, and propagules. We collected these data from the Bahamas, Belize, Florida, and Puerto Rico. Samples are primarily foliage and include four different mangrove …

Transpiration and transporters: teasing apart passive and active transport of plant silicon Open
<p>All plants contain some silicon (Si), but some species take it up passively through the transpiration stream while others additionally actively accumulate Si by producing transporters. Here, we review the literature, both qualitat…

Exploring Silica Stoichiometry on a Large Floodplain Riverscape Open
Freshwater ecosystems are critical zones of nutrient and carbon (C) processing along the land-sea continuum. Relative to our understanding of C, nitrogen (N), and phosphorus (P) cycling within the freshwater systems, the controls on silico…

Soil Warming Accelerates Biogeochemical Silica Cycling in a Temperate Forest Open
Biological cycling of silica plays an important role in terrestrial primary production. Soil warming stemming from climate change can alter the cycling of elements, such as carbon and nitrogen, in forested ecosystems. However, the effects …

Plant Uptake Offsets Silica Release From a Large Arctic Tundra Wildfire Open
Rapid climate change at high latitudes is projected to increase wildfire extent in tundra ecosystems by up to fivefold by the end of the century. Tundra wildfire could alter terrestrial silica (SiO 2 ) cycling by restructuring surface vege…

Passive experimental warming decouples air and sediment temperatures in a salt marsh Open
Open top chambers (OTCs) are a commonly used passive warming technique in experimental warming studies. OTCs have been shown to be effective in multiple types of terrestrial systems, but their utility in wetland environments remains uncert…

Biogenic silica accumulation varies across tussock tundra plant functional type Open
Silica (SiO 2 ) accumulation by terrestrial vegetation is an important component of the biological silica cycle because it improves overall plant fitness and influences export rates of silica from terrestrial to marine systems. However, mo…

Temperature response of soil respiration largely unaltered with experimental warming Open
Significance One of the greatest challenges in projecting future shifts in the global climate is understanding how soil respiration rates will change with warming. Multiple experimental warming studies have explored this response, but no c…

Carbon dioxide fluxes reflect plant zonation and belowground biomass in a coastal marsh Open
Coastal wetlands are major global carbon sinks; however, they are heterogeneous and dynamic ecosystems. To characterize spatial and temporal variability in a New England salt marsh, greenhouse gas (GHG) fluxes were compared among major pla…

Directly Measured Denitrification Reveals Oyster Aquaculture and Restored Oyster Reefs Remove Nitrogen at Comparable High Rates Open
Coastal systems are increasingly impacted by over-enrichment of nutrients, which has cascading effects for ecosystem functioning. Oyster restoration and aquaculture are both hypothesized to mitigate excessive nitrogen (N) loads via benthic…

Human appropriation of biogenic silicon – the increasing role of agriculture Open
Summary Terrestrial plants create roughly 84 Tmol biogenic silicon ( BS i) each year. This substantial uptake of dissolved silicon ( DS i) by land plants represents an important, yet often overlooked, pathway of Si on the global scale. Agr…

Does elevated CO2 alter silica uptake in trees? Open
Human activities have greatly altered global carbon (C) and Nitrogen (N) cycling. In fact, atmospheric concentrations of carbon dioxide (CO2) have increased 40% over the last century and the amount of N cycling in the biosphere has more th…
