Toward a metabolic theory of ecology

, 2004
Metabolism provides a basis for using first principles of physics, chemistry, and biology to link the biology of individual organisms to the ecology of populations, communities, and ecosystems.

Ecological impacts and limits of biomass use: a critical review

Clean Technologies and Environmental Policy, 2020
Conventional biomass sources have been widely exploited for several end uses (mostly food, feed, fuel and chemicals). More unconventional sources are continually being sought for meeting the growing planetary demands for biomass materials. Biofuels are already commercially produced in many countries and are becoming mainstream.

THE META‐ANALYSIS OF RESPONSE RATIOS IN EXPERIMENTAL ECOLOGY

, 1999
Meta-analysis provides formal statistical techniques for summarizing the results of independent experiments and is increasingly being used in ecology. The response ratio (the ratio of mean outcome in the experimental group to that in the control group ...

Comment on biomass diversity in ecology

Bulletin of Mathematical Biology, 1984
It is observed that a dynamical continuity equation for biomass distribution yields the asymptotic steady-state exponential dependencen=A exp(\( - m/\bar m\)) exhibited by certain fishery data, wherem is the biomass of an individual,n is the number of individuals per unit biomass interval, andA,\(\bar m\) are positive constants. This dynamical approach

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.

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.

Biomass allocation in boreal plants with different ecological strategies

Russian Journal of Ecology, 2000
In the boreal zone of the Middle Urals, biomass structure was studied in 35 species of wild plants with different ecological strategies according to Grime and Ramenskii (competitors, ruderals, and stress-tolerant plants). Plants belonging to these groups proved to differ considerably in the absolute plant weight and the quantitative contributions of ...

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.

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

Landscape Research, 2010
Abstract 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.
