Current PhD students

Accepted PhD students within the ClimBEco graduate research school are enrolled during two years of their PhD studies. Recruitment to the program is open during spring and accepted PhD students begin their programes in August every year.

There are two groups of PhD students enrolled simultaneously, with PhD students from both Lund university and the University of Gothenburg. 

Group 9 (2019–2021)

Alexandra Pongracz (INES, Lund University)

My PhD project WINTERGAP aims at improving physical winter process representation in the LPJ-GUESS dynamic vegetation model. The development phase consists of three sub-projects that will enhance the performance of LPJ-GUESS in simulating arctic conditions:

  1. Snow insulation
  2. Vegetation damage due to extreme events
  3. Cold season fluxes

By implementing proposed developments, we will be able to assess how the warming winter season may affect arctic ecosystems, evaluate regional permafrost-climate feedbacks and discuss the role of the Arctic in the global carbon cycle.

I investigate carbon cycling in global forest ecosystems with a focus on the decomposition of dead wood using a dynamic global vegetation model. Dead wood accumulation and decomposition are heavily affected by climate, climate change and management decisions. It has important, potentially conflicting, functions for carbon storage, biodiversity and may also increase the frequency and intensity of forest fires. Therefore, we are developing the first individual based decomposition model for a global dynamic vegetation model to provide the first estimate of dead wood in potential natural vegetation and to test the effect of dead wood management options on carbon storage and fire hazard.

My research focuses on the impacts of extreme winter events on Arctic ecology. I am interested in a community of organisms made up of cyanobacteria, mosses, lichen, bacteria and fungi called the biological soil crust (BSC). I am studying the structure and function of these BSC communities to determine their contribution to key ecosystem processes (i.e. carbon and nutrient cycling), and assess their stability under climatic change.

Within my PhD project, I try to assess the ability of ship exhaust particles to form liquid droplets and ice crystals in the atmosphere with regards to ship fuel regulations limiting the sulphur content in marine fuels as well as the observed Arctic sea-ice decline due to climate warming. I investigate these effects using different marine fuels as well as a seawater scrubber under laboratory conditions. Future work will consist of modelling studies, which will try to investigate the potential impact on mixed-phase clouds.

For my PhD research topic, I study the ecosystem-scale fluxes of Biogenic Volatile Compounds (BVOCs) from boreal forests. These BVOCs have significant impacts on global climate, and can influence regional air quality by interacting with anthropogenic pollution. Thus, by studying these BVOC fluxes, we hope to improve the current understanding of these processes.

My doctoral research project concerns policy promoting the use of agricultural biomass for energy in Sweden, to stimulate replacement of fossil fuels. Selecting a policy requires making trade-offs between societal goals that are sometimes conflicting, including energy demand, agricultural production/food security and environmental impacts. I use economic and environmental modelling to study farm production decisions and land use changes in response to policy change, to evaluate policy options.

I seek to improve the representation of tree migration and incorporate the feedbacks with additional species in the LPJ-GM model. Will migration lags slow down the spatial adaptation of vegetation to climate/land use change? Can the new model (LPJ-GMINT) be successfully applied in case studies of different interaction and dispersal types, e.g. invasive tree pests, symbionts?

Aerosol can act as cloud condensation nuclei (CCN) or ice nuclei (IN) and affects cloud microphysical properties and precipitation. Present study investigates the effect of CCN and IN on cloud microphysical characteristics and precipitation using our Aerosol-Cloud (ACM) model. Properties such as liquid water content, droplet mean size, ice concentration, and radar reflectivity from simulations are studied and compared them with aircraft and radar observations. Sensitivity tests will be performed by changing CCN and IN number concentrations.

My PhD project focuses on the impact of urbanization on organismal health and biodiversity. The aim is to investigate the interactions taking place in the cities, e.g. how avian health is affected by local prey diversity, or how the well-being of school children is impacted by contact with nature. Much of my work focuses on the complex relationship between trophic levels and diet, together with a broader perspective where urban nature is evaluated as an ecosystem service.

I am a part of the multidisciplinary research project Land4Biomass that focus on the potential of producing biomass for bioenergy on marginal land and abandoned farmland in Sweden and the ensuing consequences for biodiversity and ecosystem services in doing so. My contribution to the project involves i) an integrated analysis of the available marginal land using databases, remote sensing, GIS, and field work, and ii) an assessment of ecosystem services and biodiversity impact from the potential bioenergy-related land use change through empirical and literature studies.

In my doctoral project I focus on policy tools used to compensate for the loss of biodiversity, caused by development projects. I am mainly looking at how this policy is applied and how it have been implemented at the Swedish (national and municipal) level by tracing the transfer of the policy from the international context. In combination with a narrative analysis, I am interested in understanding the influence of norms on the non-linear, complex processes involved in the movement and implementation of the policy.

I do research on how inhaled ultrafine particles are transported and deposited in our lungs with the goal to understand how ambient air affects humans, and to explore if we can use this information to diagnose lung disease. I also study the emission factors and spread of atmospheric biological aerosol particles. I measure fluorescent aerosol particles of biological origin at Hyltemossa, an atmosphere and ecosystem research station in Skåne, with the aim to understand which factors that are crucial for the generation and spread of bioaerosols.

My PhD project aims to investigate how the soil microorganisms are affected by the presence of different types of micro(nano)plastics. To achieve this goal, I will use micro-engineered chips that contain microstructures simulating the soil pore space. These chips will be filled with several combinations of soil microbes and micro(nano)plastics and their interactions will be analyzed under a microscope.

Biological control of pests in agricultural landscapes relies in ecological interactions between the pest and its natural enemies (e.g., predators, paraistoids). Many are the processes that affect these interactions across different spatio-temporal scales. Nevertheless, this scaling has not been properly taken into consideration when studying biological control. My PhD aims to understand biological control better across different spatial (local and landscape) and temporal (ecological and evolutionary) scales.

My research focuses on the growing movement in Sweden to reduce air travel because of its climate impacts, and the potential shift in social and cultural norms it represents. In particular, I investigate how narratives associated with avoiding flying have emerged, evolved, and spread in Swedish news media and social media, and analyze the power of these narratives in fostering collective action and transformational change towards more sustainable air travel behaviours.

For my PhD I am investigating changes in the silica composition of the global ocean through geological time using silicon stable isotopes ratios on sponge spicules. A major goal of my PhD is to understand the interactions between biosilicification in organisms and how these interactions have evolved through Earth’s history. I am particularly interested in how the cycling of silica changed across the Cretaceous-Paleogene boundary 66 Ma ago after a large meteorite struck the Earth causing mass extinction of life.

In my project, I study how a landscape approach can be used to balance ecosystem services provided by Swedish production forests. I use models to plan forest management strategies and predict their outcome for several ecosystem services. I am interested in the effects of management strategies on levels of carbon stocks, soil and water quality, biodiversity and economic value and the sensitivity of these services to spatial scale.
