Biomass burning is a worldwide phenomenon, which emits large amounts of carbon into the atmosphere and strongly influences the environment. Burned area is an important parameter in modeling the impacts of biomass burning on the climate and ecosystem. The Medium Resolution Spectral Imager (MERSI) onboard FengYun-3C (FY-3C) has shown great potential for burned area mapping research, but there is ...

background and goal: burn is an irreparable event, which results in numerous physical, psychological, social, and economic complications. the burned patients should be merely treated in a professional burn center due to vast clinical range of these patients. since, a percentage of mortality in burned patients is for the patients’ transportation from other centers; this study has aimed to invest...

We monitored the riparian bird community for two years following the 1995 Vision Fire in the Point Reyes National Seashore (PRNS), Marin County, Cal i for nia. We compare bird and vegetation data on burned and unburned sites within PRNS and the Golden Gate National Recreation Area. Bird abundance, as indexed by fi xed-radius point counts, was higher for sev er al shrub-nesting species at burned...

Nationally, the causes and extent of fire on lands administrated by the United States Forest Service varied significantly from 1940 to 2000, with California experiencing the largest relative annual burned areas.The south-east and California experienced the largest relative area burned by fires from human ignitions. No significant differences were detected in the relative area burned by lightnin...

a r t i c l e i n f o The use of active fire detections for direct burned area mapping has been limited by the coarse spatial resolution and long revisit cycles of previous sensors. However, the recently developed VIIRS 375 m active fire detection product offers enhanced spatial resolution and temporal revisit cycle, and high sensitivity to small active fires. In this study, we apply that produ...

Global burned area and biomass burning emissions from small fires" (2012). NASA Publications. Paper 144. [1] In several biomes, including croplands, wooded savannas, and tropical forests, many small fires occur each year that are well below the detection limit of the current generation of global burned area products derived from moderate resolution surface reflectance imagery. Although these fi...

     This current research was investigated the long – term effects of fire on vegetation and regeneration of beech (Fagus orientalis L.) in the mountain forest in Lesakoti forests in Tonekabon city in north of Iran. In both of burnt and unburnt areas, 30 plots 1000m2 and in total 60 sampling plots were identified using random-systematic 100 m × 150 m grid and density and DBH of trees and densi...

Linville Gorge Wilderness (LGW) is a Class I area in the southern Appalachian Mountains, western North Carolina. Over the last 150 years, LGW has been subject to several wildfires, varying in intensity and extent (Newell and Peet 1995). In November 2000, a wildfire burned 4000 ha in the wilderness; the fire ranged in severity across the northern portion of the wilderness from low severity in co...

Ecosystem disturbances, such as wildfires, are driving forces that determine ecology and conservation measures. Species respond differentially to wildfires, having diverse post-fire population evolution. This study reports, for first time, the responses of brown hare (Lepus europaeus Pallas, 1778) to wildfires. Hare relative abundance, age ratio, diet quality, body condition, and diseases were ...
