Project Description

Project Overview

This four-year PhD project funded by an ERC grant explores rapid evolution's impact on host-parasite dynamics and community stability. Using wild Drosophila species and their parasitoids from tropical Australia as a novel experimental model, the project studies multigenerational eco-evolutionary dynamics through laboratory microcosms.

What You Will Do

The candidate will conduct experimental community evolution studies, apply population genomics techniques, and build eco-evolutionary models to address how rapid evolution affects the maintenance of diversity in communities and genetic variation in populations. Specific project details will be tailored together with the supervisor.

Expected Outcomes

The research will improve understanding of eco-evolutionary processes that connect population genetics and community ecology, revealing how rapid trait changes influence ecological interactions and diversity maintenance.

Why This Matters

This work addresses fundamental questions in evolutionary ecology relevant for predicting biological responses to environmental change. It also enhances knowledge about genetic and ecological stability in natural communities, providing insights valuable for conservation and biodiversity management.

Entry Requirements

A MSc degree is required to enter PhD in Czech Republic. Advantageous qualifications include research experience with laboratory experiments, population genetics or molecular ecology, and eco-evolutionary dynamics or population genetic modelling.

Research Contributions

Research on the diet breadth distribution of insect herbivores globally provides insights into ecological specialization.
This understanding aids in predicting ecosystem responses to environmental changes and biodiversity conservation.
Development and application of DNA barcoding techniques have advanced the taxonomy and phylogeny of parasitic wasps and other insects.
These methods enable more accurate species identification, improving ecological and evolutionary studies.
Molecular detection has been used to elucidate trophic links within complex insect host–parasitoid food webs.
This improves knowledge of species interactions and ecosystem functioning, which is crucial for biological control and conservation.
Studies on symbionts in food webs reveal their role in modifying interactions between insects and their natural enemies.
Understanding these interactions informs pest management and the ecological role of symbiosis.
