We are pleased to announce a PhD position in Evolutionary Biology at Lund University in Sweden. The preferred starting date is between 1 July and 1 September 2024, for a duration of four years. Project: Ecology and evolution of phenotypic plasticity in Trinidadian guppies The overall goal of the PhD project is to better understand how the environment affects genetic and phenotypic variation, and how these insights can be used to improve predictions of evolution. Evolutionary change happens constantly all around us. This contemporary evolution can allow populations to adapt and persist, or contribute to their decline and extinction. Which of the two it will be is often unclear because current methods to predict microevolution work poorly in natural populations. Considering the global environmental crisis, this is particularly alarming. A key cause of the predictive inaccuracy is environmental variation. This PhD project will investigate environmental effects on additive genetic (co)variances, narrow-sense heritabilities, and evolvabilities. Additionally, as resource availability is a crucial aspect of the environment in many species, it will evaluate to what extent including information on individual resource accrual can reduce environmental bias. The project will combine quantitative genetic experiments in a newly established, state-of-the-art fish research laboratory with analyses of long-term field data, using the well-known Trinidadian guppy system. The successful candidate will have a keen interest in evolutionary biology, quantitative genetics, or related fields. A curious mind, a sense of responsibility, and excellent organisational skills are strong additional merits for the position. Note that, while there may be a possibility for conducting fieldwork in Trinidad, the project neither requires nor guarantees it. The application deadline is 26 April 2024.
