    • A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery 

      Eikeset, Anne Marie; Richter, Andries Peter; Dankel, Dorothy; Dunlop, Erin; Heino, Mikko; Dieckmann, Ulf; Stenseth, Nils Christian (Journal article; Peer reviewed, 2012-12-12)
      Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ...
    • Assessing changes in age and size at maturation in collapsing populations of Atlantic cod (Gadus morhua) 

      Olsen, Esben Moland; Lilly, George R.; Heino, Mikko; Morgan, M. Joanne; Brattey, John; Dieckmann, Ulf (Journal article; Peer reviewed, 2005)
      By estimating probabilistic reaction norms for age and size at maturation, we show that maturation schedules of Atlantic cod (Gadus morhua) off Labrador and Newfoundland shifted toward earlier ages and smaller sizes ...
    • Body condition and evolution of maturation of Atlantic cod in Newfoundland 

      Baulier, Loïc; Heino, Mikko; Lilly, George R.; Dieckmann, Ulf (ICES CM documents, Working paper, 2006)
      Atlantic cod (Gadus morhua, L.) stocks off Newfoundland and Labrador underwent severe depletions that started in the late 1980s and led to moratoria in the early 1990s. Fisheries closures are still applied in most of the ...
    • Can integrated assessments reconcile stakeholder conflicts in marine fisheries management? 

      Dankel, Dorothy Jane; Heino, Mikko; Dieckmann, Ulf (Conference object, 2009)
    • Eco-genetic models: a new framework for understanding fisheries-induced evolution 

      Dieckmann, Ulf; Dunlop, Erin S.; Heino, Mikko (ICES CM documents, Working paper, 2006)
    • Ecological and Evolutionary Recovery of Exploited Fish Stocks 

      Enberg, Katja; Dunlop, Erin S.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2006)
    • Economic repercussions of fisheries-induced evolution 

      Eikeset, Anne Maria; Richter, Andries; Dunlop, Erin S.; Dieckmann, Ulf; Stenseth, Nils Christian (Journal article; Peer reviewed, 2013-07-23)
      Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic ...
    • Evolution of age and length at maturation of Alaskan salmon under size-selective harvest 

      Kendall, Neala W.; Dieckmann, Ulf; Heino, Mikko; Punt, André E.; Quinn, Thomas P. (Journal article; Peer reviewed, 2013-11-12)
      Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning ...
    • Evolution of reproduction periods in seasonal environments 

      Sun, Zepeng; Parvinen, Kalle; Heino, Mikko Petteri; Metz, Johan A.J.; de Roos, André M.; Dieckmann, Ulf (Peer reviewed; Journal article, 2020)
      Many species are subject to seasonal cycles in resource availability, affecting the timing of their reproduction. Using a stage-structured consumer-resource model in which juvenile development and maturation are resource ...
    • An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L. 

      Mollet, Fabian M.; Enberg, Katja Susanna; Boukal, David; Rijnsdorp, Adriaan D.; Dieckmann, Ulf (Peer reviewed; Journal article, 2023)
      Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ...
    • Exploitation as a driving force of life history evolution: methods and empirical analyses 

      Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2004)
      Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ...
    • Fisheries-Induced Changes in Age and Size at Maturation and Understanding the Potential for Selection-Induced Stock Collapse 

      Ernande, Bruno; Dieckmann, Ulf; Heino, Mikko (ICES CM documents, Working paper, 2002)
      Fishing is very likely to create selective pressures inducing adaptive changes in the life histories of harvested stocks. Using field data and adequate statistical methods, such alterations can be demonstrated. However, ...
    • Fisheries-induced evolution 

      Heino, Mikko Petteri; Diaz Pauli, Beatriz; Dieckmann, Ulf (Peer reviewed; Journal article, 2015)
    • Fisheries-induced evolution in cod 

      Heino, Mikko; Godø, Olav Rune; Dieckmann, Ulf (ICES CM documents;2010/M:24, Working paper, 2010)
      Over the last eight decades, northeast Arctic cod has shown a marked change towards earlier maturation at smaller sizes. At the same time, harvesting shifted from primarily targeting mature cod in the spawning grounds to ...
    • Fisheries-induced evolution in cod 

      Heino, Mikko; Godø, Olav Rune; Dieckmann, Ulf (ICES CM documents;2010/M:24, Working paper, 2010)
      Over the last eight decades, northeast Arctic cod has shown a marked change towards earlier maturation at smaller sizes. At the same time, harvesting shifted from primarily targeting mature cod in the spawning grounds to ...
    • Fisheries-induced evolution in Northeast Arctic cod 

      Eikeset, Anne Maria; Dunlop, Erin S.; Dieckmann, Ulf (ICES CM documents;2005/AA:16, Working paper, 2005)
      We explore the evolutionary effects of fisheries on North-East Arctic (NEA) cod. It has earlier been shown that fisheries can change the cod’s age and size at maturation in two ways: first, by reducing the biomass, which ...
    • 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)
    • Fisheries-induced trends in reaction norms for maturation in North Sea plaice 

      Grift, R.E.; Rijnsdorp, A.D.; Barot, S.; Heino, Mikko; Dieckmann, Ulf (Journal article; Peer reviewed, 2003-08-07)
      We analyse how intensive exploitation may have caused evolutionary changes in the age and length at maturation in North Sea plaice Pleuronectes platessa. Such evolutionary change in the onset of maturation is expected, ...
    • Fisheries-induced trends in reaction norms for maturation in North Sea plaice 

      Grift, R.E.; Rijnsdorp, A.D.; Barot, S.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents, Working paper, 2002)
      We analyse the potential of intensive exploitation to have caused evolutionary changes in the age and length at maturation in North Sea plaice Pleuronectes platessa. Such evolutionary change in the onset of maturation ...

      Soudijn, Floor H.; van Denderen, P. D.; Heino, Mikko Petteri; Dieckmann, Ulf; de Roos, André M. (Peer reviewed; Journal article, 2021)
