Instability of stream salmonid population dynamics under strong environmental limitations- A reply
Article Abstract:
A test was conducted to search for significant departures from linearity in the stock-recruitment relationships where the parental stock was the abundance of female spawners and recruitment, the subsequent abundance of 4-month old juveniles. It was found that positive relationships between recruitment and the subsequent abundance of adult females revealed a strong temporal synchrony where the effects of discharge on recruitment were reflected in the abundance of females about to spawn two years later.

Two-phase self-thinning in stream-living juveniles of lake-migratory brown trout Salmo trutta L. Compatibility between linear and non-linear patterns across populations?
Article Abstract:
The occurrence and shape of density-body mass relationships vis-a-vis density-dependent growth and mortality in a stream brown trout population is investigated based on the analysis of a high resolution dataset that encompassed 15 successive cohorts quantified monthly throughout their lifetime. Results permit the development of a conceptual framework of self-thinning for stream-living brown tout that may be applicable to other populations.

Environmental determinants of recruitment and their influence on the population dynamics of stream-living brown trout Salmo trutta
Article Abstract:
The dynamics of a stream-resident population of Salmo trutta in a northwestern Spain stream were examined. The study exemplifies the way an environmentally driven animal population may persist on time with little or no operation of endogenous regulatory mechanisms.
