    • Behavioural responses to human-induced change: Why fishing should not be ignored 

      Diaz Pauli, Beatriz; Sih, Andrew (Peer reviewed; Journal article, 2017-03)
      Change in behaviour is usually the first response to human-induced environmental change and key for determining whether a species adapts to environmental change or becomes maladapted. Thus, understanding the behavioural ...
    • Contemporary evolution caused by fisheries: Contributions from experimental studies 

      Diaz Pauli, Beatriz (Doctoral thesis; Peer reviewed, 2012-11-06)
      Evolutionary change is occurring within tens of generations or fewer in nature. This contemporary evolution is commonly caused by human activities, as they alter the selective pressures that the populations experience. ...
    • Density-dependent consequences of size-selective induced life-history changes to population fitness in medaka (Oryzias latipes) 

      Evangelista, Charlotte; Vøllestad, Leif Asbjørn; Diaz Pauli, Beatriz; Edeline, Eric (Journal article; Peer reviewed, 2020)
      There is an increasing concern about the potential for size-selective harvest to impair population persistence. Yet little is known about the relative contribution of the evolutionary (shifts in life history) and demographic ...
    • Ecological and evolutionary effects of harvesting: lessons from the candy-fish experiment 

      Diaz Pauli, Beatriz; Heino, Mikko Petteri (Peer reviewed; Journal article, 2013-11)
      Understanding the challenges of sustainable fisheries management is not easy for non-specialists, and even many specialists fail to appreciate the potential evolutionary consequences of harvest. We propose candy-fish ...
    • Ecosystem consequences of multi-trait response to environmental changes in Japanese medaka, Oryzias latipes 

      Diaz Pauli, Beatriz; Edeline, Eric; Evangelista, Charlotte (Journal article; Peer reviewed, 2020)
      Intraspecific trait variation has large effects on the ecosystem and is greatly affected by human activities. To date, most studies focused on single-trait analyses, while considering multiple traits is expected to better ...
    • Effects of ambient oxygen and size-selective mortality on maturation and growth in guppies 

      Diaz Pauli, Beatriz; Kolding, Jeppe; Jeyakanth, Geetha; Heino, Mikko Petteri (Peer reviewed; Journal article, 2017)
      Growth, onset of maturity and investment in reproduction are key traits for understanding variation in life-history strategies. Many environmental factors affect variation in these traits, but for fish, hypoxia and ...
    • Fisheries-induced evolution 

      Heino, Mikko Petteri; Diaz Pauli, Beatriz; Dieckmann, Ulf (Peer reviewed; Journal article, 2015-12)
      Increased mortality from fishing is expected to favor faster life histories, realized through earlier maturation, increased reproductive investment, and reduced postmaturation growth. There is also direct and indirect ...
    • 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 ...
    • 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 ...
    • Stoichiometric consequences of size-selective mortality: An experimental test using the Japanese medaka (Oryzias latipes) 

      Evangelista, Charlotte; Diaz Pauli, Beatriz; Vøllestad, Leif Asbjørn; Edeline, Eric (Journal article; Peer reviewed, 2020-07-01)
      The determinants of intraspecific stoichiometric variation remain difficult to elucidate due to their multiple ori- gins (e.g. genetic vs. environmental) and potential interactive effects. We evaluated whether two size-selected ...
    • Trade-off between mate choice speed and decision accuracy under mating competition in female sand gobies 

      Diaz Pauli, Beatriz; Lindström, Kai (Journal article; Peer reviewed, 2020)
      Variation in female mating performance can affect the direction and rate of evolution through sexual selection. The social environment determines the availability of mates and the competitive situation, and hence can ...
    • 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 ...
