Evaluation of the temporal development of three introduced populations of brook trout, Salvelinus fontinalis, in Jizerské mountains, Czech Republic [PDF]
Archives of Biological Sciences, 2015 Three populations of brook trout, Salvelinus fontinalis, established in streams and reservoirs in the Jizerské Mountains, Czech Republic, were studied between 1995 and 2006. The maximum age was usually 3+ to 4+, but the age 7+ was also recorded.

Density-dependent regulation of brook trout population dynamics along a core-periphery distribution gradient in a central Appalachian watershed. [PDF]
PLoS ONE, 2014 Spatial population models predict strong density-dependence and relatively stable population dynamics near the core of a species' distribution with increasing variance and importance of density-independent processes operating towards the population ...
