Effects of Fire Retardant Chemical and Fire Suppressant Foam on Shrub Steppe Vegetation in Northern Nevada
The objectives of this study were to determine the effects of fire retardant chemical (Phos-Chek G75-F*) and fire suppressant foam (Silv-Ex) application, alone and in combination with fire, on Great Basin shrub steppe vegetation. We measured growth, resprouting, flowering, and incidence of galling insects on Chrysothamnus viscidiflorus and Artemisia tridentata. These characteristics were not af...
متن کاملRegulation of seed germination and seedling growth by chemical signals from burning vegetation.
It is well known that burning of vegetation stimulates new plant growth and landscape regeneration. The discovery that char and smoke from such fires promote seed germination in many species indicates the presence of chemical stimulants. Nitrogen oxides stimulate seed germination, but their importance in post-fire germination has been questioned. Cyanohydrins have been recently identified in aq...
متن کاملA Modular Neural Network Approach to Chemical Content Analysis of Vegetation
The state of a plant affects its chlorophyll content, which in turn, affects the way the plant reflects light. Consequently, the characteristics of the reflected light can be used to determine the health of a plant. This raises the possibility of monitoring large areas of vegetation by analyzing the reflectance of the plants in the area. This paper discusses the use of neural networks for analy...
متن کاملImpact of forest vegetation on soil characteristics: a correlation between soil biological and physico-chemical properties
Temperate and dry deciduous forest covers major portion of terrestrial ecosystem in India. The two forest types with different dominant tree species differ in litter quality and root exudates, thereby exerting species-specific impact on soil properties and microbial activity. This study aims to examine the influence of forest type or dominant tree species on soil physico-chemical properties and...
متن کاملVegetation change impacts on soil organic carbon chemical composition in subtropical forests
Changes in the chemical composition of soil organic carbon (SOC) might strongly affect the global carbon cycle as it controls the SOC decomposition rate. Vegetation change associated with long-term land use changes is known to strongly impact the chemical composition of SOC; however, data on the impacts of vegetation change following disturbance events of short durations and succession that occ...
