Fisheries-induced evolution of body size and other life history traits: the impact of gear selectivity
Boukal, David S.; Dunlop, Erin S.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents;2008/F:07, Working paper, 2008) -
How does stochasticity affect evolutionary regime shifts in age and size at maturation?
Boukal, David S.; Roos, Andre M. de; Persson, Lennart (ICES CM documents, Working paper, 2006)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. We have shown ... -
Length structure of deep-pelagic fishes sheds new light to their life histories
Heino, Mikko; Boukal, David S.; Falkenhaug, Tone; Piatkowski, Uwe; Porteiro, Filipe M.; Sutton, Tracey T. (ICES CM documents;2008/C:14, Working paper, 2008)Here we use a new technique to study life history variation in deep-pelagic fishes from a midocean ridge system. Shape of length distribution in a population is to a significant extent determined by the degree to which ... -
On the interplay of environmental changes and fishing pressure in exploited fish stocks
Boukal, David S.; de Roos, Andre M.; Persson, Lennart; Heino, Mikko (ICES CM documents;2010/M:15, Working paper, 2010)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. At the same ... -
Size structure, age-size dynamics and life history variation
Heino, Mikko; Boukal, David S.; Falkenhaug, Tone; Piatkowski, Uwe; Porteiro, Filipe M.; Sutton, Tracey T. (ICES CM documents;2008/F:13, Working paper, 2008)Here we present a new technique to study life history variation when only length distributions of populations are known. Shape of length distribution in a population is to a significant extent determined by the degree ...
