Localization: Small experiments for the coming downshift
(2013-10-24)
The circumstances being faced are urgent, some global, many overwhelming. It would seem that only large responses will suffice. But this is a version of the homeopathic delusion (Berry 2011): here that only large solutions ...
Quality of life and environmental constraints: An annotated bibliography
(CPL Bibliographies, 1983)
The economic profession implicitly assumes that satisfaction and happiness are not directly measurable. Thus, economists have worked at developing indicators, usually counted in dollars, to act as proxies for these ...
Seasonal changes in the respiratory electron transport system (ETS) and respiration of the zebra mussel, Dreissena polymorpha in Saginaw Bay, Lake Huron
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-04)
Electron transport system activity (ETS) and respiration rates (R) of the zebra mussel, Dreissena polymorpha , were determined monthly from April to November over 2 years at two sites in Saginaw Bay, Lake Huron. The sites ...
An ecologically-based approach to the design of intercrop agroecosystems: An intercropping system of soybeans and tomatoes in Southern Michigan
(Elsevier, 1984-10)
A model is developed in which the elementary structure of plant competision is translated into the classical yield-density equation. Using the same reasoning, an interspecific form of the model is formulated to predict ...
Resistance and resilience in a directly regenerating rainforest: Nicaraguan trees of the Vochysiaceae after Hurricane Joan
(Elsevier, 1994-10)
Two trees of the family Vochysiaceae, Vochysia ferruginea and Qualea paraensis, were abundant in a Nicaraguan rainforest which was heavily damaged by Hurricane Joan in 1988, and both had recovered their previous densities ...
Fungal community composition and metabolism under elevated CO 2 and O 3
(Springer-Verlag, 2006-02)
Atmospheric CO 2 and O 3 concentrations are increasing due to human activity and both trace gases have the potential to alter C cycling in forest ecosystems. Because soil microorganisms depend on plant litter as a source ...
Coastal eutrophication assessment in the United States
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2006-04-21)
Recent national assessments document that nitrogen-driven coastal eutrophication is widespread and increasing in the United States. This significant coastal pollution problem includes impacts including increased areas and ...
Forecasting the Impact of Connected and Automated Vehicles on Energy Use: A Microeconomic Study of Induced Travel and Energy Rebound
(Elsevier, 2019-06-04)
Connected and automated vehicles (CAVs) are expected to yield significant improvements in safety, energy efficiency, and time utilization. However, their net effect on energy and environmental outcomes is unclear. Higher ...
A yield model for walking catfish production in aquaculture systems
(Elsevier, 1988-06-15)
A yield model for Clarias culture was produced using a combination of laboratory data for Clarias lazera and field data on Clarias batrachus culture in Thailand. The model was used for simulations to fulfil three distinct ...
Some Psychological Aspects of Living Lightly: Desired Lifestyle Patterns and Conservation Behavior
(Baywood Publishing Company, Inc., 1990)
It has been argued that an environmentally compatible lifestyle is a necessary if somewhat onerous component of a sustainable society. This perception might lead one to demand compensation for adopting such a lifestyle. ...
