Building fire-adaptive communities and fostering fire-resilient landscapes have become two of the main research strands wildfire science that go beyond strictly biophysical viewpoints call for integration complementary visions living there, with their legacy knowledge subjective dimensions. Both indigenous fire management (IFM) local (LFM) are rooted in traditional among most important contribu...

Abstract Context. Tree hollows are a key habitat resource for hollow-nesting species, including the northern Australian Gouldian finch (Erythrura gouldiae). Certain fire and disturbance regimes limit tree hollow availability in savannas. Aims. This study investigated influence of regime vegetation structure on density at breeding sites. Methods. Fire scars were mapped across sites by using LAND...

  Background & Objectives: Educational and research laboratories in universities have a high risk of fire, because they have a variety of materials and equipment. The aim of this study was to provide a technical plan for safety improvement in educational and research laboratories of a university based on the design of automatic detection, alarm, and extinguishing systems .   Method...

Forest fire models are generally used in different aspects of fire management and are helpful in understanding and prediction of fire behavior. Forest fires cause a significant damage for public property by destroying a large tract of forest.  This helps fire fighters to focus on an area with greater risk and to develop better substructure for fire fighter training and ultimately to plan fire-f...

r.-Previous research has found that exposure to fire-related cues enhances germination of some plant species, and such species may exist in frequent-fire southwestern United States Pinus ponderosa forests. I performed four greenhouse experiments with Penstemon barbatus, a perennial forb common in P ponderosa forests, testing seed responses to liquid and air smoke, charred P ponderosa wood and l...

A key pursuit in contemporary ecology is to differentiate regime shifts that are truly irreversible from those hysteretic. Many ecological have been labeled as without exploring the full range of variability stabilizing feedbacks potential drive an shift back towards a desirable regime. Removing fire grasslands can juniper woodlands cannot be reversed using typical frequency and intensity thres...

The question as to how Action Research (AR) is related to Cultural Historical Activity Theory (CHAT) is not answerable in categorical terms. Both CHAT and AR have been variously interpreted and much depends on the individual biographies of those who pronounce on their relationship. In this paper, therefore, I offer no more than my own answer to this question, based on my own research trajectory...
