Unearthing belowground bud banks in fire‐prone ecosystems [PDF]

New Phytologist, 2018
SummaryDespite long‐time awareness of the importance of the location of buds in plant biology, research on belowground bud banks has been scant. Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud‐bearing structures, are used inconsistently in the literature.

Fire Mosaics and Reptile Conservation in a Fire‐Prone Region

Conservation Biology, 2012
Abstract Fire influences the distribution of fauna in terrestrial biomes throughout the world. Use of fire to achieve a mosaic of vegetation in different stages of succession after burning (i.e., patch‐mosaic burning) is a dominant conservation practice in many regions.

Evolutionary ecology of resprouting and seeding in fire‐prone ecosystems

New Phytologist, 2014
SummaryThere are two broad mechanisms by which plant populations persist under recurrent disturbances: resprouting from surviving tissues, and seedling recruitment. Species can have one of these mechanisms or both. However, a coherent framework explaining the differential evolutionary pressures driving these regeneration mechanisms is lacking.

Managing Fire to Avoid Wildfires in Fire-prone Ecosystems

2021
<p>Fire-prone ecosystems evolved and have been managed by humans with fire for<br>millennia. Ignoring these socioecological realities, zero-fire policies have been<br>implemented in fire-prone ecosystems across the world. These inappropriate policies are<br>mainly originated from a forest-centered

Reimagining fire management in fire-prone northern Australia

2015
Summary The northern savannas, occupying a quarter of the Australian land mass, constitute the most fire-prone landscapes of a fiery land – in recent years, on average, 18% of the savannas have been burnt each year. Land use is predominantly given over to extensive beef cattle pastoralism – although over much of the rangelands this is

Australian fires offer insight into fire-prone future

New Scientist, 2013
Climate change is ramping up fire risk around the world and in Australia, home to some of the most fire-prone regions on Earth, the raging bush fires could be a taster of what's to ...

Allelopathic mechanism in fire-prone communities

1992
The Southeastern Coastal Plain of the USA supports two different communities on its upland, sandy soils. The communities share a common subtropical climate with heavy rains, seasonally concentrated in the summer. Both are exposed to fires on a regular basis, and both are dominated by pines (Pinus spp) and oaks (Quercus spp).

Chemical inhibition of fire-prone grasses by fire-sensitive shrub,Conradina canescens

Journal of Chemical Ecology, 1989
In an investigation of potential chemical activity of fire-sensitive shrubs in Florida's sand pine scrub community, bioassays of foliar washes ofConradina canescens showed significant inhibitory activity on three native grasses that are known to fuel frequent surface fires; inhibition was concentrated seasonally in spring and summer.

Hysteresis of fire-prone weather to CO2 forcing

2023
CO2 emission from biomass burning (BB) is one of the essential elements of the global carbon budget, with its annual mean of about 2.0 PgC/year equivalent to 15 % of 2020 fossil fuel emissions. However, while a global increase in fire-prone weather is projected alongside climate change, a quantitative understanding of how much carbon will further be ...
