Atmospheric processing of iron-bearing mineral dust aerosol and its effect on growth of a marine diatom, Cyclotella meneghiniana Atmospheric processing of iron-bearing mineral dust aerosol and its effect on growth of a marine diatom, Cyclotella meneghiniana
Iron (Fe) is a growth-limiting micronutrient for phytoplankton in major areas of oceans and deposited wind-blown desert dust is a primary Fe source to these regions. Simulated atmospheric processing of four mineral dust proxies and two natural dust samples followed by subsequent growth studies of the marine planktic diatom Cyclotella meneghiniana in artificial sea-water (ASW)...

Forest management under megadrought: Urgent actions needed at finer-scale and higher intensity Forest management under megadrought: Urgent actions needed at finer-scale and higher intensity
Drought and warming increasingly are causing widespread tree die-offs and extreme wildfires. Forest managers are struggling to improve anticipatory forest management practices given more frequent, extensive, and severe wildfire and tree die-off events triggered by “hotter drought”—drought under warmer than historical conditions. Of even greater concern is the increasing probability of...

Subsea permafrost carbon stocks and climate change sensitivity estimated by expert assessment Subsea permafrost carbon stocks and climate change sensitivity estimated by expert assessment
The continental shelves of the Arctic Ocean and surrounding seas contain large stocks of organic matter (OM) and methane (CH4), representing a potential ecosystem feedback to climate change not included in international climate agreements. We performed a structured expert assessment with 25 permafrost researchers to combine quantitative estimates of the stocks and sensitivity of organic...

Upper Colorado River Basin 20th century droughts under 21st century warming: Plausible scenarios for the future Upper Colorado River Basin 20th century droughts under 21st century warming: Plausible scenarios for the future
This study builds on a collaboration with a water resource management community of practice in the Upper Colorado River Basin to develop scenarios of future drought and assess impacts on water supply reliability. Water managers are concerned with the impacts of warming on water year streamflow, but uncertainties in projections of climate make the application of these projections to...

Effects of postfire climate and seed availability on postfire conifer regeneration Effects of postfire climate and seed availability on postfire conifer regeneration
Large, severe fires are becoming more frequent in many forest types across the western United States and have resulted in tree mortality across tens of thousands of hectares. Conifer regeneration in these areas is limited because seeds must travel long distances to reach the interior of large burned patches and establishment is jeopardized by increasingly hot and dry conditions. To...

Tidal wetland resilience to increased rates of sea level rise in the Chesapeake Bay: Introduction to the special feature Tidal wetland resilience to increased rates of sea level rise in the Chesapeake Bay: Introduction to the special feature
The papers in this Special Feature are the result of the first Marsh Resilience Summit in the Chesapeake Bay region, which occurred in February 2019. The Chesapeake Bay region has one of the highest rates of relative sea level rise in the U.S., jeopardizing over 1000 km2 of tidal wetlands along with other coastal lands. The goal of the Summit and this collection of articles is to analyze...

Expert assessment of future vulnerability of the global peatland carbon sink Expert assessment of future vulnerability of the global peatland carbon sink
The carbon balance of peatlands is predicted to shift from a sink to a source this century. However, peatland ecosystems are still omitted from the main Earth system models that are used for future climate change projections, and they are not considered in integrated assessment models that are used in impact and mitigation studies. By using evidence synthesized from the literature and an...

Forest restoration and fuels reduction: Convergent or divergent? Forest restoration and fuels reduction: Convergent or divergent?
For over 20 years, forest fuel reduction has been the dominant management action in western US forests. These same actions have also been associated with the restoration of highly altered frequent-fire forests. Perhaps the vital element in the compatibility of these treatments is that both need to incorporate the salient characteristics that frequent fire produced—variability in...

The geography of islands The geography of islands
Islands come in all shapes, sizes and types, from tiny rocky outcrops, to enormous continental landmasses. The true number of islands distributed in the planet’s seas and oceans is still elusive. Recent efforts bolstered by an abundance of detailed satellite imagery and the sophistication of geographic information systems (GIS) are bringing real answers to those questions closer than...

A comparison of plant communities in restored, old field, and remnant coastal prairies A comparison of plant communities in restored, old field, and remnant coastal prairies
Temperate grasslands are experiencing worldwide declines due to habitat conversion. Grassland restoration efforts are employed to compensate for these losses. However, there is a need to better understand the ecological effects of grassland restoration and management practices. We investigated the effects of three different grassland management regimes on plant communities of coastal...

Evaluating natural experiments in ecology: Using synthetic controls in assessments of remotely sensed land treatments Evaluating natural experiments in ecology: Using synthetic controls in assessments of remotely sensed land treatments
Many important ecological phenomena occur on large spatial scales and/or are unplanned and thus do not easily fit within analytical frameworks that rely on randomization, replication, and interspersed a priori controls for statistical comparison. Analyses of such large‐scale, natural experiments are common in the health and econometrics literature, where techniques have been developed to...

Increased burning in a warming climate reduces carbon uptake in the Greater Yellowstone Ecosystem despite productivity gains Increased burning in a warming climate reduces carbon uptake in the Greater Yellowstone Ecosystem despite productivity gains
1. The effects of changing climate and disturbance on mountain forest carbon stocks vary with tree species distributions and over elevational gradients. Warming can increase carbon uptake by stimulating productivity at high elevations but also enhance carbon release by increasing respiration and the frequency, intensity, and size of wildfires. 2. To understand the consequences of climate...
