Abstract

Fossils document the existence of trees and wood-associated organisms from almost 400 million years ago, and today there are between 400,000 and 1 million wood-inhabiting species in the world. This is the first book to synthesise the natural history and conservation needs of wood-inhabiting organisms. Presenting a thorough introduction to biodiversity in decaying wood, the book studies the rich diversity of fungi, insects and vertebrates that depend upon dead wood. It describes the functional diversity of these organisms and their specific habitat requirements in terms of host trees, decay phases, tree dimensions, microhabitats and the surrounding environment. Recognising the threats posed by timber extraction and forest management, the authors also present management options for protecting and maintaining the diversity of these species in forests as well as in agricultural landscapes and urban parks.

Abstract

This Technical brief is a short summary of the results obtained from the laboratory and field trials conducted by Climarice project team, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to evaluate the potentials of microbial inoculants (biofertilizers) such as Blue Green Algae, Azolla and Phosphobacteria in minimizing the impacts of climate change in rice cultivation by nutrient supplementation, methane emission reduction and carbon sequestration. Cyanobacteria (Blue green algae) as a biofertilizer for rice in supplementing nitrogen is highly promising as the rice field ecosystem provides congenial environment for this self supporting diazotroph. Azolla is a floating water fern that also fixes atmospheric nitrogen. Azolla and Cyanobacteria have been identified as eco-friendly natural nitrogen fixers in the rice field ecosystem. A judicious use of these blue green algae could provide entire rice acreage of India as much nitrogen as obtained from 15-17 lakh tonnes of urea. Cyanobacterial nitrogen fixation helps to minimize the over dependence of chemicals, in particular, urea in rice farming and also enhances the use efficiency of nitrogen by releasing ammonia constantly to the rice crop.
