Savannas are a major terrestrial biome, comprising of grasses with the C4 photosynthetic pathway and trees with the C3 type. This mixed grass-tree biome rapidly appeared on the ecological stage 8 million years ago with the near-synchronous expansion of C4 grasses around the…

Fire has been shown to stimulate seed germination in a number of fire-prone ecosystems, mainly in Mediterranean type shrublands and, though not exclusively, in hardseeded species. Stimulation by heat, or by chemical constituents of charred wood and smoke, have been identified as…

Soil seed banks that persist after a fire are important in fire-prone habitats as they minimise the risk of decline or local extinction in plants, should the fire-free interval be less than the primary juvenile periods of the species. In two common woody plant genera (Acacia and…

The past decade has seen an increasing interest in forest management based on historical or natural disturbance dynamics. The rationale is that management that favours landscape compositions and stand structures similar to those found historically should also maintain…

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…

From the introduction: Let me emphasize that I only claim to speak with authority about the task of restoring fire to the National Forests. Private landowners have their own special problems in using prescribed fire, size of forest tracts, lack of expertise, etc. Before we can…

Cuban Parrots (Amazona leucocephala) on the island of Great Abaco in the Bahamas forage and nest in native pine forests. The population is unique in that the birds nest in limestone solution holes on the forest floor. Bahamian pine forests are fire-dependent with a frequent…

Boreal forests are highly susceptible to wildfire, and post-fire changes in soil temperature and moisture have the potential to transform large areas of the landscape from a net sink to a net source of carbon (C). Understanding the ecological controls that regulate these…

Savannas are the most common vegetation type in the tropics and subtropics, ranging in physiognomy from grasslands with scattered woody plants to woodlands with heterogeneous grass cover. Productivity and organic matter turnover in savannas are controlled by interactions between…

Radiocarbon signatures Delta 14C of carbon dioxide CO2 provide a measure of the age of C being decomposed by microbes or respired by living plants. Over a 2-year period, we measured Delta 14C of soil respiration and soil CO2 in boreal forest sites in Canada, which varied…

The contribution of wildfire in peatlands outside of boreal and tropical regions to interannual variability of global carbon emissions has been relatively little studied. There are 0.19 to 0.88 million km^2 of localized peat deposits in the temperate zone (30-50 degrees latitude…
