Thermodynamic approach to biomass distribution in ecological systems

Bulletin of Mathematical Biology, 1983
In the derivation of the biomass distribution function for an ecological population critical use is made of an energetic constraint on the maximization of biomass diversity. The nature of this constraint is explored in detail using Kleiber's relation σ(m) = cmγ between animal metabolic rate σ(m) and body weight m in conjunction with the Prigogine-Wiame

Control for Ecological Improvement of Small Biomass Boilers

IFAC Proceedings Volumes, 2009
Abstract The aim of this paper is to present various types of research on reducing emissions in the flue gases produced by low-power biomass boilers, especially when the boilers operate outside their nominal operating regime. This long-term investigation program is being carried out on a pilot boiler in the university laboratories.

Soil Ecology and Factors Affecting Biomass

2009
Effluents containing pharmaceuticals and hormones from CAFOs are of concern because they are directly applied to the soil without any pre-treatment. To evaluate the potential affect of these compounds, an understanding of soil ecology is required. Soil ecology is a daunting topic as there is so much soil mass and diversity in the world.

Promoting Ecological Sustainability in Woody Biomass Harvesting

Journal of Forestry, 2010
Abstract Enthusiasm for the use of forest biomass as an energy resource is growing as a result of increased energy costs and a desire to reduce the greenhouse gas emissions responsible for climate change. Although the opportunity exists for forests to have a significant role in the development and use of bioenergy technologies ...

Microbial and higher plant biomass selection for closed ecological systems

Acta Astronautica, 1992
A selection of higher plants and microbial strains is presented with its rationale in order to progressively regenerate food from waste in future space and planetary missions.

Meta-analysis of ecological and phylogenetic biomass maturity metrics

Waste Management
Although a wide variety of biomass sources have been subjected to 16S rRNA gene sequencing, ecological and phylogenetic signatures of maturity have not been identified quantitatively. In this meta-analysis we reanalyzed data from the only published study with publicly available 16S and temperature data (Zhou et al., 2018), and then applied the Zhou ...

Carbon Claims and Energy Landscapes: Exploring the Political Ecology of Biomass

Landscape Research, 2010
The greatest proportion (83%) of renewable energy in the UK is derived from biomass. Despite this there has been little debate over the potential landscape impacts of biomass, and the sector is characterized by considerable levels of uncertainty. This paper explores the ways in which biomass is framed within the carbon debate, interrogating the trade ...

Ecological effects of harvesting biomass for energy in the Spanish Mediterranean

Landscape and Urban Planning, 1993
Abstract Biomass utilization for energy has major consequences for Spanish Mediterranean landscapes. In this paper we present a synthesis of the ecological effects of harvesting biomass for energy. We compare these effects with other fuel reduction procedures such as prescribed burning.

Biomass and the Problems of Ecology, Agrochemistry and Energy

1991
Publisher Summary This chapter describes the biomass and the problems of ecology, agrochemistry, and energy. There are a number of possible applications of modern biomass—the major accumulator of solar energy on the Earth—as an additional fuel source.
