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

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.

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.
