In previous studies published from this laboratory (1) it was shown that 2 major factors are implicated in the production of burn shock in mice and rats; the one, fluid loss at the site of the thermal injury, and the other, stagnation of blood in atonic visceral capillaries. Capillary atony was demonstrated in burn shock whether thermal trauma was accompanied by much or little local fluid loss....

The Blake Fire burned about 730 ha of mature timber on the west slope of South Fork Mountain in northwestern California. Many steep innergorge and landslide headwall areas burned very hot, killing most large trees and consuming much of the large organic debris in unstable drainages. This created a potential for adverse effects on downstream fisheries from landsliding and the release of sediment...

Field fires can modify soil nutrient cycling and alter microbial communities (SMC), although the latter is not well understood. In southern region of Puerto Rico, field have become a significant problem during dry season. To mimic effects fire, we performed prescribed on hillside at Juana Díaz Agricultural Experiment substation in October 2015 March 2017. A complete randomized block design was ...

Fire is a major force driving the evolution of plants and the structure and function of ecosystems globally. It thus likely operates as an important environmental filter that selects for species that have evolved to tolerate and depend on fire. Across a 40-year experimental fire gradient from frequently burned open savanna to unburned dense woodland in Minnesota, USA, we examined the relationsh...

Support vector machines are shown to be highly effective in mapping burn extent from hyperspatial imagery grasslands. Unfortunately, this pixel-based method is hampered forested environments that have experienced low-intensity fires because unburned tree crowns obstruct the view of surface vegetation. This obstruction causes misclassified as unburned. To account for misclassifying areas under c...

Jepson Prairie in Solano County, an outstanding example of remnant California Central Valley vernal pool and grassland habitats, is threatened by invasive exotic species. This paper describes the results of a 200-acre late-spring prescribed fire conducted at Jepson Prairie in June of 1995 and aimed at reducing the cover of an extensive infestation of Medusahead (Taeniatherum caput-medusae). Bur...
