Selección sexual y dinámica de poblaciones en ácaros: post-doc de tres años en Polonia

Oferta compartida por Nuria

Post-doc position in evolutionary biology is available for three years, preferably starting October-December 2021 but subject to negotiations, in a project “Sex, aggression and ecology – how sexual selection alters population dynamics?”. This collaborative project is led by Jacek Radwan (Adam Mickiewicz University, Poznan), Rob Knell (Queen Mary University, London) and Tom Cameron (University of Essed), and is funded by Polish Science Centre (NCN).

Project summary: 
In recent years an increasing awareness that sexual selection may play a crucial role in larger scale processes such as adaptation to altered environments and population persistence has developed, but empirical support for this role is extremely inconsistent. The aim of the proposed project is to resolve this inconsistencies by using a combination of simulation modelling and laboratory experiments. Laboratory experiments investigate the effects of sexual selection on a variety of ecologically important variables and on population dynamic behaviour. We will use an experimental system that is uniquely suited for this purpose, the soil mite Sancassania berlesei, which can be readily cultured and manipulated in the lab and is male-dimorphic with respect to sexually selected weapon. The proportion of armoured, aggressive males in the population can be easily manipulated experimentally, which allows varying the strength of sexual selection. We will test whether (i) sexual selection interacts with population size in determining population dynamics and persistence in face of environmental population and (ii) whether sexual selection affect carrying capacity and if it interacts in this respect with environmental complexity. Theoretical work will examine how the effects of different mating systems impact on the overall effects of strong sexual selection, and will explore the ecological effects of sexual selection in a wide range of scenarios.

The post-doc will be will be responsible for the experimental evolution part, but will also contribute to model development. The candidate should hold PhD degree in biological sciences and should have significant achievements in evolutionary biology or ecology as documented by publications in international scientific journals. S/he should be able to work well as part of a team, have good planning, analytical, statistical and writing skills. and should be ready to work hard in the field.
