    Evolutionary History and Not Heterochronic Modifications Associated with Viviparity Drive Head Shape Differentiation in a Reproductive Polymorphic Species, Salamandra salamandra

    Identifying the evolutionary processes that underlie morphological variation at the intraspecific level is cornerstone for understanding the drivers of phenotypic diversity at higher macro-evolutionary scales....

    Map** of quantitative trait loci for life history traits segregating within common frog populations

    The evolution of complex traits is often shaped by adaptive divergence. However, very little is known about the number, effect size, and location of the genomic regions influencing the variation of these trait...

    Constrained plasticity in switching across life stages: pre- and post-switch predators elicit early hatching

    The timing of many life history events shows phenotypic plasticity in response to the risk of predation. Theory predicts that increased risk of mortality in an early stage should select for switching earlier, ...

    Trade-offs across life stages: does predator–induced hatching plasticity reduce anuran post-metamorphic performance?

    In species with complex life cycles hatching plasticity can provide an effective escape from egg predators, but theoretical studies predict a predation-risk trade-off across egg and larval stages. In this stud...

    Factors determining tadpole vulnerability to predators: can prior experience compensate for a suboptimal shape?

    We investigated the role of constitutive morphology and previous experience in predator avoidance in two anuran species associated with different larval habitats. In Rana temporaria, deeper tails and larger body ...

    Microgeographic variation in metabolic rate and energy storage of brown trout: countergradient selection or thermal sensitivity?

    We examined the influence of habitat size, growth opportunity, and the thermal conditions experienced during early development on the standard metabolic rate (SMR) of juvenile brown trout (Salmo trutta) from six ...
