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 ...
Simulation of the potential for life history components to regulate walleye population size
(Elsevier, 1989-02)
A bioenergetic life history simulation model was applied to identify components of the walleye (Stezostedion vitrium) life history that had a potential for population regulation. The model combined a predator-prey model, ...
Contaminant uptake by fish and the potential for transfer to humans modelled over time
(Elsevier, 1986-07)
A model is developed that enables coupling of contaminant uptake with the growth dynamics of fish, exploitation, and transfer and fate. Contaminant concentration in fish is a function of the properties of the contaminant, ...
Simple models for exploitative and interference competition
(Elsevier, 1987-02)
Competition is exploitative when species compete for the same limited resource, and interference when species deplete one another's resources by interferences such as aggressive displays or fighting. If pure exploitative ...
Modeling nutrient behavior in Wetlands
(Elsevier, 1988-01)
A simple mathematical model os developed which permites dynamic simulation of wetland hydrology and of nutrient-driven interactions between wastewater and the wetland ecosystem. Spatial variations due to surface water flow ...
Impact of a once-through cooling system on the yellow perch stock in the western basin of lake erie
(Elsevier, 1982-03)
The surplus production model, a conventional fishery stock assessment model, is applied to assess the entrainment and impingement impact of the Monroe Power Plant on the yellow perch standing stock and fishery in the western ...
Modeling the annual thermal regime of lake Ohrid, Yugoslavia, using daily weather data
(Elsevier, 1982-03)
The time-dependent characteristics of the five weather variables which control the annual thermal response of Lake Ohrid are analyzed in detail. These are daily values for solar radiation, air temperature, humidity, wind ...
