The present knowledge base and stressor status of 48 large (450 km 2 or greater in area) Arctic lakes in Canada are reviewed. The lakes occur from the southern territorial boundaries to the northern-most extent of land in the Archipelago, and range i

Action in theoretical physics is an abstract quantity describing the overall motion of a system; action has the dimensions of energy X time (in joule-seconds). The Principle of Least Action states that physical systems follow that path for which the

The dominant fish populations in undisturbed arctic lakes are characterized as being in a state of "least specific dissipation": the greatest biomass attainable for a given energy input. A survey of autonomous ecosystems in various parts of the world

Previous research indicated that fish populations in arctic lakes maintain a constant size distribution and abundance in the face of the environmental variability experienced over their recent history. Such stability was tested over 15 seasons in Lit

The general attributes of ecosystems are examined and a naturally occurring “reference ecosystem” is established, comparable with the “isolated” system of classical thermodynamics. Such an autonomous system with a stable, periodic input of en

The fundamental problem in ecology is the relationship between organisms and the physical world. This question is approached through the study of ecosystems as wholes. Pristine, autonomous Arctic lakes provide an invaluable starting point for such in

Eight sexually mature sockeye ( Oncorhynchus nerka ) and one sexually mature pink salmon ( O. gorbuscha ) were captured in the subsistence fishery in the Sachs River estuary at Sachs Harbour, Banks Island, Northwest Territories (NT) in August 1993. W

The properties of autonomous Arctic lake ecosystems, within the context of the whole living World, provide the basis for y development of a thermodynamic theory of the biosystem. The biosystem is now undergoing a process of internal reordering. Energ

The available data on the fish populations of 35 lakes in the Northwest Territories are examined. The lakes range in size from Great Bear Lake (31, 156 km2) to Keyhole Lake (46 ha); they are situated between lat. 60 and 75° N, east from the Mackenzi
