• Artificial selection on allometry: change in elevation but not slope 

      Egset, Camilla Kalvatn; Hansen, Thomas F; Le Rouzic, Arnaud; Bolstad, Geir Hysing; Rosenqvist, Gunilla; Pelabon, Christophe (Journal article; Peer reviewed, 2012)
      To what extent within-species (static) allometries constitute a constraint on evolution is the subject of a long-standing debate in evolutionary biology. A prerequisite for the constraint hypothesis is that static allometries ...
    • Complex constraints on allometry revealed by artificial selection on the wing of Drosophila melanogaster 

      Bolstad, Geir Hysing; Cassara, Jason A.; Marquez, Eladio; Hansen, Thomas F; van der Linde, Kim; Houle, David; Pelabon, Christophe (Journal article, 2015)
      Precise exponential scaling with size is a fundamental aspect of phenotypic variation. These allometric power laws are often invariant across taxa and have long been hypothesized to reflect developmental constraints. Here ...
    • Demographic measures of an individual's "pace of life": fecundity rate, lifespan, generation time, or a composite variable? 

      Araya-Ajoy, Yimen; Bolstad, Geir Hysing; Brommer, Jon; Careau, Vincent; Dingemanse, Niels J.; Wright, Jonathan (Journal article; Peer reviewed, 2018)
      Comparative analyses have demonstrated the existence of a ^pace-of-life^ (POL) continuum of life-history strategies, from fastreproducing short-lived species to slow-reproducing long-lived species. This idea has been ...
    • Evolution of morphological allometry 

      Pelabon, Christophe; Firmat, Cyril Joel Patrick; Bolstad, Geir Hysing; Voje, Kjetil L.; Houle, David; Cassara, Jason; Le Rouzic, Arnaud; Hansen, Thomas F (Journal article, 2014)
      Morphological allometry refers to patterns of covariance between body parts resulting from variation in body size. Whether measured during growth (ontogenetic allometry), among individuals at similar developmental stage ...
    • Evolution of Signals: Genetic Architecture, Natural Selection and Adaptive Accuracy 

      Bolstad, Geir Hysing (Doktoravhandlinger ved NTNU, 1503-8181; 2011:55, Doctoral thesis, 2011)
    • Geographical variation in allometry in the guppy (Poecilia reticulata) 

      Egset, Camilla Kalvatn; Bolstad, Geir Hysing; Rosenqvist, Gunilla; Endler, John A; Pelabon, Christophe (Journal article; Peer reviewed, 2011)
      Variation in static allometry, the power relationship between character size and body size among individuals at similar developmental stages, remains poorly understood. We tested whether predation or other ecological factors ...
    • Intersexual conflict over seed size is stronger in more outcrossed populations of a mixed-mating plant 

      Raunsgard, Astrid; Opedal, Øystein Hjorthol; Ekrem, Runa K; Wright, Jonathan; Bolstad, Geir Hysing; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2018)
      In polyandrous species, fathers benefit from attracting greater maternal investment toward their offspring at the expense of the offspring of other males, while mothers should usually allocate resources equally among ...
    • Life-history evolution under fluctuating density-dependent selection and the adaptive alignment of pace-of-life syndromes 

      Wright, Jonathan; Bolstad, Geir Hysing; Araya-Ajoy, Yimen; Dingemanse, Niels J. (Journal article; Peer reviewed, 2018)
      We present a novel perspective on life-history evolution that combines recent theoretical advances in fluctuating density-dependent selection with the notion of pace-of-life syndromes (POLSs) in behavioural ecology. These ...
    • Novel microsatellite markers for Dalechampia scandens(Euphorbiaceae) and closely related taxa:application to studying a species complex 

      Falahati-Anbaran, Mohsen; Stenøien, Hans K.; Bolstad, Geir Hysing; Hansen, Thomas F; Pérez‐Barrales, Rocio; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2016)
      We developed novel microsatellite markers for D alechampia scandens L. (Euphorbiaceae). The target plants belong to a distinct, but undescribed, species in the D . scandens species complex, characterized by small resin-producing ...
    • On the relationship between ontogenetic and static allometry 

      Pelabon, Christophe; Bolstad, Geir Hysing; Egset, Camilla Kalvatn; Cheverud, James M.; Pavlicev, Mihaela; Rosenqvist, Gunilla (Journal article; Peer reviewed, 2013)
      Ontogenetic and static allometries describe how a character changes in size when the size of the organism changes during ontogeny and among individuals measured at the same developmental stage, respectively. Understanding ...
    • The effect of purging on sexually selected traits through antagonistic pleiotropy with survival 

      Bolstad, Geir Hysing; Pelabon, Christophe; Larsen, Line-Kristin; Fleming, Ian A.; Viken, Åslaug; Rosenqvist, Gunilla (Journal article; Peer reviewed, 2012)
      Sexually selected traits are expected to evolve to a point where their positive effect on reproductive success is counterbalanced by their negative effect on survival. At the genetic level, such a trade-off implies ...
    • The measure and mismeasure of reciprocity in heterostylous flowers 

      Armbruster, W. Scott; Bolstad, Geir Hysing; Hansen, Thomas F; Keller, Barbara; Conti, Elena; Pelabon, Christophe (Journal article; Peer reviewed, 2017)
      The goal of biological measurement is to capture underlying biological phenomena in numerical form. The reciprocity index applied to heterostylous flowers is meant to measure the degree of correspondence between fertile ...
