Canebrakes are monodominant stands of cane (Arundinaria gigantea [Walter] Muhl .), a bamboo native to and once prominent in the southeastern USA. Canebrakes were important wildlife habitat within the bottomland hardwood forest ecosystem. They have been reduced in areal coverage by an estimated 98 % since European settlement due to land conversion and the drastic alteration of disturbance regime...

Mountain forests are subjected to several pressures including historical land-use changes and climate warming which may lead shifts in wildfire severity negatively impacting tree species with low post-fire growth resilience. This is the case of relict Mediterranean Scots pine (Pinus sylvestris) Sierra de Gredos mountains (central Spain). We reconstructed fire regime these since 1700 by using pa...

Introduction Many people that read this chapter may be aware of mammals, birds, and maybe even plant species that are common at Pt. Reyes, and may have witnessed or have been aware of the ways that these organisms responded to the Mt. Vision fire of 1995. Few will be familiar with fungal species at Pt. Reyes, and even fewer may have noticed their response to the fire. This is unfortunate, becau...

Abstract Fire blight represents a great threat to apple and pear production worldwide. The ability of its causal agent, Erwinia amylovora , spread rapidly in the host plants makes this devastating disease difficult manage. Copper antibiotics are still most effective solutions control fire blight, although their application contribute environmental pollution development E. resistant populations....

Fire can destroy infrastructure and livelihoods, claim lives. Yet, fire is inevitable plays several vital ecological roles that have shaped ecosystems over millennia. Planned fires also serve human needs. Critical media content analysis of 390 reports (print, online broadcast) on in South African National Parks a three-year period were used to investigate the portrayal by mass media. We found s...

Fire is one of Earth's most potent agents ecological change. This Special Issue comes in the wake a series extreme wildfires across world, from Amazon, to Siberia, California, Portugal, South Africa and eastern Australia (Duane et al., 2021). These “megafires,” variously defined according their size, intensity, or impacts (Attiwill & Binkley, 2013), are perhaps signature feature fiery transitio...

within the national forests of the west, is one of the most contentious natural resource issues in the US today. One recent response to the controversy is the Healthy Forests Restoration Act (HFRA) of 2003 (Public Law 108-V148). This law has potentially profound consequences for forests and their biodiversity and must therefore be implemented on the basis of the best scientific information and ...

Understanding and predicting changes in the abundance of natural populations is a central goal of ecology. These changes are influenced by a variety of exogenous processes (weather, floods, fire); variation in these processes leads to variation in vital rates (survival, fecundity) that may be positively or negatively correlated across the life cycle. We used 20 years of data and a hierarchical ...
