Výzkumné zaměření

I am a freshwater ecologist focusing on insects, using Odonata as a model group to understand patterns of diversity, species’ vulnerability, and responses to global change, with conservation implications. Drawing on functional traits and next-generation sequencing, I study what shapes species’ capacity to adapt, from genetic variation to the role of microbial symbionts.

2026–2028: Anticipating freshwater biota responses to climate-driven habitat shifts based on the evolutionary history of lotic and lentic odonates (Lotic2Lentic; funded by UP Young Researcher Grant Competition, JG_2026_006; Consultant: Dr Cesc Múrria, University of Barcelona), role: Principal Investigator Description: Freshwater habitats sit along a spectrum: from fast-flowing rivers and streams (lotic habitats) to calmer lakes, ponds and wetlands (lentic habitats). Lotic2Lentic asks a simple question: does where a species falls on that spectrum affect how well it will cope with climate change? We expect the answer is yes. Species from flowing waters tend to be specialists (i.e., closely adapted to local conditions), but poor dispersers. Species from still waters tend to be generalists (i.e., more mobile and flexible), able to adjust to new conditions more easily. If that’s true, running water species should be more vulnerable to climate change, while stagnant water species should be more resilient. Using dragonflies as our model group, we’re studying the genetic and functional diversity of species across this running-to-stagnant water gradient, to understand what shapes their capacity to adapt. Our ultimate goal is to pinpoint the genes involved in this adaptation, which will let us predict which species are most at risk, and which are likely to cope well, as the climate continues to change.
2025–2027: Maladaptive behavior and species turnover as a key to understanding the vulnerability of freshwater communities to rapid environmental changes (funded by Grant Agency of the Czech Republic, 25-16274S), role: Co-Principal Investigator (Co-Principal Investigator: Dr Filip Harabiš, Czech University of Life Sciences Prague) Description: Human activities are changing environments much faster than species can adapt, exposing animals to novel conditions and decoupling the cues they use to select habitats from the habitats’ true quality, which can create ecological traps. Using freshwater model organisms (amphibians, beetles, bugs, and dragonflies) and restored post-mining sites, we investigate how animals select habitats, why they sometimes prefer habitats that cannot sustain their populations, what makes those habitats poor, and how these choices affect the offspring fitness and survival of future generations. Our aim is not only to understand these processes but also to apply the findings in restoration, so that restored habitats are of genuinely high quality and not just attractive to animals.
2025–2028: Odonates as barometers for global change: understanding the evolution of latitudinal ranges to anticipate response mechanisms to climate warming (EvoLatitude; funded by Ministerio de Cinecia, Innivación y Universidades, Spain, PID2024-162136NB-I00; Principal Investigator: Dr Cesc Múrria, University of Barcelona), role: External Collaborator Description: As the climate warms, species must shift, adapt, or decline. EvoLatitude uses seven closely related dragonfly species (Onychogomphus, Ophiogomphus, Paragomphus), spanning North Africa to Scandinavia, as a natural experiment in coping with heat and drought. By combining distribution data, traits, and genetics, we ask how these species came to occupy their ranges, how flexible individuals are across environments, and which genes underlie adaptation to hotter, drier conditions. The results will help predict how dragonflies, and potentially other species, respond to climate change and inform conservation of those most at risk.
