The changes in species composition mediate direct effects of climate change on future fire regimes of boreal forests in northeastern China The changes in species composition mediate direct effects of climate change on future fire regimes of boreal forests in northeastern China
Direct effects of climate change (i.e. temperature rise, changes in seasonal precipitation, wind patterns and atmospheric stability) affect fire regimes of boreal forests by altering fire behaviour, fire seasons and fuel moisture. Climate change also alters species composition and fuel characteristics, which subsequently alter fire regimes. However, indirect effects of climate change are...

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...

Spatially explicit reconstruction of post-megafire forest recovery through landscape modeling Spatially explicit reconstruction of post-megafire forest recovery through landscape modeling
Megafires are large wildfires that occur under extreme weather conditions and produce mixed burn severities across diverse environmental gradients. Assessing megafire effects requires data covering large spatiotemporal extents, which are difficult to collect from field inventories. Remote sensing provides an alternative but is limited in revealing post-fire recovery trajectories and the...

Substantially greater carbon emissions estimated based on annual land-use transition data Substantially greater carbon emissions estimated based on annual land-use transition data
Quantifying land-use and land-cover change (LULCC) effects on carbon sources and sinks has been very challenging because of the availability and quality of LULCC data. As the largest estuary in the United States, Chesapeake Bay is a rapidly changing region and is affected by human activities. A new annual land-use and land-cover (LULC) data product developed by the U.S. Geological Survey...

Surface soil temperature seasonal variation estimation in a forested area using combined satellite observations and in-situ measurements Surface soil temperature seasonal variation estimation in a forested area using combined satellite observations and in-situ measurements
Surface soil temperature is the soil temperature from the surface to 10 cm in depth. Surface soil temperature plays a significant role in agricultural drought monitoring, ecosystem energy transfer modeling, and global carbon cycle evaluation. Studies have been proposed to estimate surface soil temperature, but surface soil temperature monitoring within forested areas still poses a...

Carbon stock losses and recovery observed for a mangrove ecosystem following a major hurricane in Southwest Florida Carbon stock losses and recovery observed for a mangrove ecosystem following a major hurricane in Southwest Florida
Studies integrating mangrove in-situ observations and remote sensing analysis for specific sites often lack precise estimates of carbon stocks over time frames that include disturbance events. This study quantifies change in mangrove area from 1985 to 2018 with Landsat time series analysis, estimates above and belowground stored carbon using field data, and evaluates aboveground carbon...
