Climate and the match or mismatch between predator requirements and resource availability (2007, background): “In the case of many commercially exploited fish stocks, fisheries-induced selection pressure has decreased the genetic and age variation, which often leads to spawning becoming more restricted in time and space, thus increasing the risk for a total year class failure (Ottersen et al. 2006).”
Projected impacts of climate change on marine fish and fisheries (2013, background): “…andﬁshingevenwithacenturyofdata(Engelhard et al. , 2011; Hofstede and Rijnsdorp, 2011), whereas others note that ﬁsheries can amplify or moderate climate signals (Ottersen et al ., 2006).”
Climate change and the future for coral reef fishes (2008, background): “Numerous studies have demonstrated a strong link between climatic fluctuations, such as El Niño and La Niña events, and the distribution or productivity of exploited fish populations (Lehodey et al. 1997; O’Brien et al. 2000; Worm et al. 2005; Ottersen et al. 2006).”
Fishing effects on age and spatial structures undermine population stability of fishes (2009, background): “…responsible for the collapse of Atlantic cod stock off Newfoundland (Olsen et al. 2004, 2005), recruitment failure of the Arcto-Norwegian cod stock (Ottersen et al. 2006), declined lifetime egg production for rockfishes (O’Farrell and Botsford 2006a, 2006b), and reduced reproductive output of…”
Synergistic effects of fishing-induced demographic changes and climate variation on fish population dynamics (2011, background): “In consequence, fishing might alter the ability of populations to buffer the effects of external forces through the sizeselective harvesting of larger and older individuals (Ottersen et al. 2006, Anderson et al. 2008, Ottersen 2008, Stenseth & Rouyer 2008).”
Environmental variability and fisheries: what can models do? (2008, background): “…ways to environmental changes but also populations of the same species do so in different localities (Skud 1982; Alheit and Bernal 1993; Francis et al. 1998; Hare and Mantua 2000; Alheit and Ñiquen 2004) as do the different age-classes of populations (Coulson et al. 2001; Ottersen et al. 2006).”
Resolving the effect of climate change on fish populations (2009, background): “Fishing will reduce the size and age structure of a population and reduce its bet-hedging capabilities that would allow it to track conditions suitable for the survival of eggs and larvae (Rothschild, 1986; Ottersen et al., 2006).”
Cod and climate in a latitudinal cline: physiological analyses of climate effects in marine fishes (2008, background): “…and for commercial fish species like cod Gadus morhua many studies focus on the relationship between climate condition and stock or population size and structure (e.g. Pepin et al. 1997, Otterlei et al. 1999, Brander & Mohn 2004, Ottersen et al. 2006, Stige et al. 2006, Takasuka et al. 2007, 2008).”
Fisheries-induced evolution: present status and future directions (2007, background): “In the short term of population dynamics, concentrating just on the protection of small, young fish leads to truncation of the size and age distributions (e.g. Ottersen et al. 2006).”
