An ECOPATH II model of the Lake Chad system
Type: Book Chapter
The trophic ecosystem modelling software, ECOPATH II, was used to analyze the Lake Chad system, Africa, during its "normal" phase, the period between 1969 and 1972. Reasonable estimates of population-related parameters for ...
Modeling and analyzing the agroecological performance of farms with ECOPATH
Type: Report
Intensive and integrated resource management, where field crops, vegetables, trees, livestock and fish production are combined through efficient reuse of wastes, residues, by-products and external inputs, offers a potential ...
Integrated smallholder agriculture aquaculture in Asia: optimizing trophic flows
Type: Book Chapter
A nutrient modelling approach was applied to show how the combination of crops, trees, livestock, and fish, that is, integrated agriculture-aquaculture (IAA), helps in optimizing trophic flows in Asian rice-based agroecosystems. ...
Applying systems ecology to the analysis of integrated agriculture-aquaculture farms
Type: Journal Article
The article suggests a preliminary list of properties as a point of departure for quantifying various ecological facets of the integrated agriculture-aquaculture farms.
Artificial reefs for marine habitat enhancement in Southeast Asia
Type: Brief
This study highlights the potential role of artificial reefs in Coastal Resource Management in the ASEAN region. It discusses the considerations necessary to maximize the effectiveness of artificial reefs as a means for ...
A quantitative approach for assessing the productive performance and ecological contributions of smallholder farms
Type: Journal Article
A pragmatic framework for monitoring, modelling, analysing, and comparing the state and performance of integrated agroecosystems is proposed. Four smallholder rice farms (1.36€“2.76 hectares) €” including monoculture rice ...
Resources ecology of the Bolinao coral reef system
Type: Journal Article
The book describes an intensive four-year program of monitoring the community ecology and harvest patterns of a large fringing coral reef system in northeastern Philippines. Reef harvest methods included principally ...
Bulletin of the Institute of Marine Biology and Oceanography: special edition
Type: Book
This special edition of the Bulletin of the Institute of Marine Biology and Oceanography is dedicated to Professor Daniel Emanuel Babatunji Chaytor who has been Director of this Institute for two decades before he was ...
Life cycle and biological parameters of several Brazilian Amazon fish species
Type: Journal Article
This contribution summarizes knowledge on the biology (population dynamics, reproduction, ecology) of 25 fish species from the Lower Amazon, Brazil, based on data from a Brazilian-German field project (IARA) and a review ...
Structuring dynamic models of exploited ecosystems from trophic mass-balance assessment
Type: Journal Article
The linear equations that describe trophic fluxes in mass-balance, equilibrium assessments of ecosystems (such as in the ECOPATH approach) can be re-expressed as differential equations defining trophic interactions as ...
