Distinguishing random environmental fluctuations from ecological catastrophes for the North Pacific Ocean

Article Abstract:

A study was conducted to show that time series observations of key variables for the North Pacific Ocean are not deterministically nonlinear, and are best described as linear stochastic. The results addressed a continuing debate over the origin of rapid shifts in certain key marine observation and the measurements suggested that large-scale marine eco-systems are dynamically nonlinear, and have the capacity for dramatic change in response to stochastic fluctuations in basin-scale physical states.

Fishing elevates variability in the abundance of exploited species

Article Abstract:

Evidence is presented from the marine environment that exploited species exhibiting higher temporal variability in abundance than unexploited species. The increased variability of exploited populations is probably caused by fishery-induced truncation of the age structure and the double jeopardy of fishing to potentially deplete stock sizes and, more immediately, to amplify the peaks and valleys of population variability, calls for a precautionary management approach.
