Does schooling reduce fast-start response latencies in teleosts?
(Elsevier, 1980)
1. 1. Response latencies, denned as the time between a d.c. electric shock and initiation of a fast-start (startle response) were measured for eight species of teleosts.2. 2. Fast-start response latencies varied from 10 ...

Kinetics of nitrogen and phosphorus release in varying food supplies by Daphnia magna
(Kluwer Academic Publishers; Dr. W. Junk Publishers ; Springer Science+Business Media, 1982-10)
Rates of nitrogen and phosphorus release from individual Daphnia magna were determined by measuring ammonia and soluble reactive phosphorus in successive 10-min incubations in small (0.05 ml) vessels after the animals were ...
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 ...
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 ...
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 ...
Ethnicity and preference for natural settings: A review and recent findings
(Elsevier, 1988-06)
Substantial differences have been found between the recreational pursuits of blacks and whites. In the related area of environmental preference, however, agreement generally exists across many cultural groups. None the ...
