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 ...

On biomass diversity in ecology

Bulletin of Mathematical Biology, 1983
We postulate that the biomass distribution function for an ecological population may be derived from the condition that the biomas diversity functional is maximal subject to an energetic constraint on the total biomass. This leads to a biomass distribution of the form $$p(m ...

The ecology of fear and inverted biomass pyramids

Oikos, 2020
In inverted biomass pyramids (IBPs) prey are outnumbered by their predators when measured by biomass. We investigate how prey should behave in the face of danger from higher predator biomass, and how anti‐predator behavior (in the form of vigilance) can, in turn, affect the predator–prey system.

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 ...

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
