Measuring ecological stress: variations on a theme by R.M. Warwick
Type: Journal Article
Two new indices are presented which reflect quantitatively the changes to be expected in an ecological community under stress, as previously described by R. M. Warwick. The indices summarize information which he presented ...
The climate and eastern ocean systems project
Type: Journal Article
A brief description of the NMFS/ORSTOM/ILCARM climate and Eastern Ocean systems (CEOS) project is given. CEOS will study the four major eastern boundary current regions (Peru/Chile, California, Northwest and Southwest ...
On holism, reductionism and working from 9 to 5
Type: Journal Article
A discussion is presented on the 2 approaches - holism and reductionism - in the study of environmental sciences, making reference to various projects presently being conducted by ICLARM and its collaborators using the ...
Changes in models of aquatic ecosystems approaching carrying capacity
Type: Journal Article
Using a top-down modeling approach, published mass-balance models of trophic interactions and state variables in the western central Pacific Ocean and the northern Gulf of Mexico shelf were used to explore how large increases ...
The South China Sea: analyzing fisheries catch data in an ecosystem context
Type: Journal Article
The South China Sea is an important fishing area with an annual harvest of some 5 million tonnes, or 10% of the catches jointly taken by the developing nations of the world. Details are given of a model of the area describing ...
Fish production, catches and the carrying capacity of the world oceans
Type: Journal Article
A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH ...
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 ...
