  • Behavioural adjustment in response to increased predation risk : a study in three duck species 

    Zimmer, Cedric; Boos, Mathieu; Bertrand, Frederic; Robin, Jean-Patrice; Petit, Odile (2011-04-20) - Journal article
    Predation directly triggers behavioural decisions designed to increase immediate survival. However, these behavioural modifications can have long term costs. There is therefore a trade-off between antipredator behaviours ...
  • Evidence of the trade-off between starvation and predation risks in ducks 

    Zimmer, Cedric; Boos, Mathieu; Poulin, Nicolas; Gosler, Andrew; Petit, Odile; Robin, Jean-Patrice (2011-07-18) - Journal article
    The theory of trade-off between starvation and predation risks predicts a decrease in body mass in order to improve flight performance when facing high predation risk. To date, this trade-off has mainly been validated in ...
  • Fecundity and the demographic strategies of coral morphologies 

    Álvarez-Noriega, Mariana; Baird, Andrew H.; Dornelas, Maria; Madin, Joshua S.; Cumbo, Vivian R.; Connolly, Sean R. (2016-09-07) - Journal article
    Understanding species differences in demographic strategies is a fundamental goal of ecology. In scleractinian corals, colony morphology is tightly linked with many demographic traits, such as size-specific growth and ...
  • Matters of scale : positive allometry and the evolution of male dimorphisms 

    Tomkins, JL; Kotiaho, JS; LeBas, NR (2005-03) - Journal article
    The developmental independence of alternative phenotypes is key to evolutionary theories of phenotypic plasticity and the origins of diversity. Male dimorphisms associated with alternative reproductive tactics are widely ...
  • The trade-off between starvation and predation risk in overwintering redshanks (Tringa totanus) 

    Sansom, Alex (University of St Andrews, 2010-06-23) - Thesis
    In order to meet their energy budget animals must often increase their risk of predation, either through their choice of foraging location or by decreasing anti-predation behaviours, which are incompatible with foraging. ...
