Fires in the Cenozoic: a late flowering of flammable ecosystems
Modern flammable ecosystems include tropical and subtropical savannas, steppe grasslands, boreal forests, and temperate sclerophyll shrublands. Despite the apparent fiery nature of much contemporary vegetation, terrestrial fossil evidence would suggest we live in a time of low fire activity relative to the deep past. The inertinite content of coal, fossil charcoal, is strikingly low from the Eo...
متن کاملFire as a global 'herbivore': the ecology and evolution of flammable ecosystems.
It is difficult to find references to fire in general textbooks on ecology, conservation biology or biogeography, in spite of the fact that large parts of the world burn on a regular basis, and that there is a considerable literature on the ecology of fire and its use for managing ecosystems. Fire has been burning ecosystems for hundreds of millions of years, helping to shape global biome distr...

متن کاملAn Economic Evaluation of Iranian Horticultural Research and Extension Policy: The Case Study of Almond Late Flowering Cultivars
This paper examines the economic effects of investment in developing and introducing Almond Late Flowering Cultivars (ALFC) in a period of 52 years from 1968 to 2020, developed in Sahand Horticultural Research Station (SHRS), using the economic surplus model and field survey data. ALFC make almond supply curve move less to the left when there is a chilling case, thus affect the economic surplus...
متن کاملGenetic interactions among late-flowering mutants of Arabidopsis.
Flowering time in Arabidopsis is controlled by a large number of genes, identified by induced mutations. Forty-two double mutants involving 10 of these loci were obtained and analyzed for their flowering behavior under long-day conditions, with and without vernalization, and under short-day conditions. The genetic interactions between the various mutants proved to be complex, although a major e...
