Genetic introgression of farmed salmon in native populations: quantifying the relative influence of population size and frequency of escapees
Heino, Mikko Petteri; Svåsand, Terje; Wennevik, Vidar; Glover, Kevin (Peer reviewed; Journal article, 2015-02-11)Farmed escapees may threaten the genetic integrity of native salmon populations through interbreeding. However, introgression requires survival until maturation, successful reproduction and successful early development. ... -
A global biogeographic classification of the mesopelagic zone
Sutton, Tracey T.; Clark, Malcolm R.; Dunn, Daniel C.; Halpin, Patrick N.; Rogers, Alex D.; Guinotte, John; Bograd, Steven J.; Angel, Martin V; Perez, Jose Angel A; Wishner, Karen F.; Haedrich, R.L.; Lindsay, Dhugal J.; Drazen, Jeffrey C; Vereshchaka, A.; Piatkowski, Uwe; Morato, Telmo; Błachowiak-Samołyk, Katarzyna; Robison, Bruce H.; Gjerde, Kristina M.; Pierrot-Bults, Annelies; Bernal, Patricio; Reygondeau, Gabriel; Heino, Mikko Petteri (Peer reviewed; Journal article, 2017-08)We have developed a global biogeographic classification of the mesopelagic zone to reflect the regional scales over which the ocean interior varies in terms of biodiversity and function. An integrated approach was necessary, ... -
Harvesting forage fish can prevent fishing-induced population collapses of large piscivorous fish
Soudijn, Floor H.; van Denderen, P. D.; Heino, Mikko Petteri; Dieckmann, Ulf; de Roos, André M. (Journal article; Peer reviewed, 2021)Fisheries have reduced the abundances of large piscivores—such as gadids (cod, pollock, etc.) and tunas—in ecosystems around the world. Fisheries also target smaller species—such as herring, capelin, and sprat—that are ... -
The importance of social dimension and maturation stage for the probabilistic maturation reaction norm in Poecilia reticulata
Diaz Pauli, Beatriz; Heino, Mikko Petteri (Peer reviewed; Journal article, 2013-10-01)Maturation is an important event in an organism's life history, with important implications on dynamics of both wild and captive populations. The probabilistic maturation reaction norm (PMRN) has emerged as an important ... -
The importance of social dimension and maturation stage for the probabilistic maturation reaction norm in Poecilia reticulata
Diaz Pauli, Beatriz; Heino, Mikko Petteri (Peer reviewed; Journal article, 2013-10)Maturation is an important event in an organism's life history, with important implications on dynamics of both wild and captive populations. The probabilistic maturation reaction norm (PMRN) has emerged as an important ... -
Latitudinal differences in early growth of largehead hairtail (Trichiurus japonicus) in relation to environmental variables
Sun, Peng; Chen, Qi; Fu, Caihong; Xu, Yi; Sun, Runlong; Li, Jianchao; Yu, Haiqing; Zhang, Chi; Liu, Yang; Ye, Zhenjiang; Tian, Yongjun; Heino, Mikko Petteri (Journal article; Peer reviewed, 2020)Largehead hairtail (Trichiurus japonicus) in the China Seas shows an increasing catch trend, despite continued overexploitation, which could be attributed to improved recruitment as a result of strengthened early growth. ... -
Life histories determine divergent population trends for fishes under climate warming
Wang, Hui-Yu; Shen, Sheng-Feng; Chen, Ying-Shiuan; Kiang, Yun-Kae; Heino, Mikko Petteri (Journal article; Peer reviewed, 2020-08-14)Most marine fish species express life-history changes across temperature gradients, such as faster growth, earlier maturation, and higher mortality at higher temperature. However, such climate-driven effects on life histories ... -
Life-history implications of the allometric scaling of growth
Boukal, David S.; Dieckmann, Ulf; Enberg, Katja; Heino, Mikko Petteri; Jørgensen, Christian (Peer reviewed; Journal article, 2014-10-21)Several phenomenological descriptions, such as the von Bertalanffy growth model, have been widely used to describe size-at-age and individual growth across a diverse range of organisms. However, for modelling life histories, ... -
Modeling fitness changes in wild Atlantic salmon populations faced by spawning intrusion of domesticated escapees
Castellani, Marco; Heino, Mikko Petteri; Gilbey, John; Araki, Hitoshi; Svåsand, Terje; Glover, Kevin (Peer reviewed; Journal article, 2018-07)Genetic interaction between domesticated escapees and wild conspecifics represents a persistent challenge to an environmentally sustainable Atlantic salmon aquaculture industry. We used a recently developed eco‐genetic ... -
Modern cities modelled as “super-cells” rather than multicellular organisms: Implications for industry, goods and services
Chang, Jie; Ge, Ying; Wu, Zhaoping; Du, Yuanyuan; Pan, Kaixuan; Yang, Guofu; Ren, Yuan; Heino, Mikko Petteri; Mao, Feng; Cheong, Kang Hao; Qu, Zelong; Fan, Xing; Min, Yong; Peng, Changhui; Meyerson, Laura A. (Journal article; Peer reviewed, 2021)The structure and “metabolism” (movement and conversion of goods and energy) of urban areas has caused cities to be identified as “super-organisms”, placed between ecosystems and the biosphere, in the hierarchy of living ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
Diaz Pauli, Beatriz; Wiech, Martin; Heino, Mikko Petteri; Utne-Palm, Anne Christine (Peer reviewed; Journal article, 2015-03)This study assessed whether fishing gear was selective on behavioural traits, such as boldness and activity, and how this was related with a productivity trait, growth. Female guppies Poecilia reticulata were screened for ... -
Rapid life‑history evolution in a wild Daphnia pulex population in response to novel size‑dependent predation
Wathne, Ingrid; Enberg, Katja; Jensen, Knut Helge; Heino, Mikko Petteri (Journal article; Peer reviewed, 2020)The effect of size-selective predation on prey communities and their traits is well documented, but the relative roles of genetic adaptation and phenotypic plasticity continue to be debated. We looked for evidence of genetic ... -
Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
Gíslason, Davíð; Heino, Mikko Petteri; Robinson, Beren W.; McLaughlin, Robert B.; Dunlop, Erin S. (Peer reviewed; Journal article, 2019-01-06)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation.

Baulier, Loic; Morgan, M. Joanne; Lilly, George R.; Dieckmann, Ulf; Heino, Mikko Petteri (Peer reviewed; Journal article, 2017-08-31)Life history theory predicts selection for higher reproductive investment in response to increased mortality among mature individuals.

Size-selective harvesting affects the immunocompetence of guppies exposed to the parasite Gyrodactylus
Bartuseviciute, Vitalija; Pauli, Beatriz Diaz; Salvanes, Anne Gro Vea; Heino, Mikko Petteri (Journal article; Peer reviewed, 2022)Harvesting is typically size-selective, targeting large individuals. This is expected to lead to reduced average body size and earlier maturation (i.e. faster life histories). Such changes can also affect traits seemingly ... -
What can selection experiments teach us about fisheries-induced evolution?
Diaz Pauli, Beatriz; Heino, Mikko Petteri (Peer reviewed; Journal article, 2014-03)There is evidence that fisheries are altering the phenotypic composition of fish populations, often in ways that may reduce the value of fish stocks for the exploiters. Despite the increasing number of theoretical and field ...
